1. Introduction
What this service is
Telecom Subscriber Insights is a Google Cloud Industry solutions offering aimed at helping telecom organizations build a unified, analytics-ready view of subscribers by combining network, billing, CRM, and digital engagement data—then turning it into actionable insights (for example churn risk, experience issues, segmentation, and propensity).
Simple explanation (one paragraph)
If you work at a telecom operator, subscriber data is scattered across many systems (BSS/OSS, CDRs, CRM, app events, contact center, network telemetry). Telecom Subscriber Insights is a Google Cloud solution approach for bringing those datasets together, organizing them into consistent subscriber-centric data models, and enabling analytics and ML so business and operations teams can make faster, better decisions.
Technical explanation (one paragraph)
In practice, Telecom Subscriber Insights is typically implemented using Google Cloud data and AI building blocks—such as BigQuery for the analytics warehouse, Cloud Storage for landing zones, streaming/batch ingestion (often Pub/Sub + Dataflow or other ingestion tools), and BI/semantic layers (Looker or Looker Studio). You then apply governance and security (IAM, Cloud Logging, Dataplex, DLP, CMEK) and optionally ML (BigQuery ML and/or Vertex AI) to support production-grade subscriber analytics.
What problem it solves
Telecom organizations often struggle with:
– Fragmented subscriber identity and inconsistent IDs across systems
– Long lead times to produce “single view of customer” metrics
– Limited ability to correlate customer experience with network performance
– Manual reporting, duplicated data marts, and unclear data governance
– Difficulty operationalizing churn/upsell models into repeatable pipelines
Telecom Subscriber Insights focuses on solving these by providing a solution pattern on Google Cloud for subscriber-centric data integration, analytics, governance, and activation.
Important note on scope and naming: Telecom Subscriber Insights is presented by Google Cloud as an industry solution/solution offering rather than a single standalone “API service” in the way that BigQuery or Pub/Sub are. Capabilities and implementation details may vary by version, partner delivery, and engagement model. Verify the current official scope, reference architectures, and any packaged assets in the official Google Cloud documentation before committing to a production design.
2. What is Telecom Subscriber Insights?
Official purpose
Telecom Subscriber Insights is intended to help telecom providers build subscriber analytics that unify business, network, and digital signals to improve customer experience, reduce churn, and increase revenue through personalization and better operational decisions.
Because it is an Industry solutions offering, it is best understood as: – A reference approach (and sometimes packaged assets) for modeling and analyzing subscriber data on Google Cloud – A set of recommended Google Cloud services and architectural patterns
Core capabilities (typical for this solution pattern)
- Unified subscriber view by joining identities and attributes across CRM/BSS/OSS/app/network data
- Subscriber segmentation (prepaid/postpaid, ARPU bands, tenure cohorts, device types, region/coverage segments)
- Churn and propensity analytics using SQL-based features and ML models
- Experience correlation (linking complaints, dropped calls, latency, and ticket data to subscriber outcomes)
- Operational dashboards for care, marketing, and network ops stakeholders
- Governance and privacy controls for sensitive subscriber PII
Major components (implementation building blocks on Google Cloud)
Telecom Subscriber Insights commonly uses:
– BigQuery as the analytics warehouse and SQL engine
– Cloud Storage as the raw/landing zone (batch files, exports, archives)
– Ingestion and processing (commonly Pub/Sub + Dataflow for streaming and/or batch pipelines; other ingestion options may be used depending on your sources—verify in official docs)
– BI and semantic layer (often Looker; Looker Studio is a lightweight alternative for labs and small teams)
– Governance (Dataplex, Data Catalog capabilities, policy controls; verify current product integration paths)
– Security (IAM, Cloud KMS, VPC Service Controls for data exfiltration controls in higher-security environments)
– ML (BigQuery ML for in-warehouse modeling; Vertex AI for more advanced pipelines)
Service type
- Type: Industry solution (solution pattern composed of multiple Google Cloud services)
- Control plane: Managed by you through Google Cloud projects and service configurations
- Data plane: Runs across the data services you choose (BigQuery, Dataflow, etc.)
Scope (regional/global/zonal)
Because Telecom Subscriber Insights is built from underlying services, its scope depends on the resources you create:
– BigQuery datasets are created in a chosen location (US, EU, or a region).
– Cloud Storage buckets are regional/dual-region/multi-region.
– Pipelines (Dataflow, etc.) run in chosen regions.
– IAM and org policies are organization-wide but applied to projects/folders.
How it fits into the Google Cloud ecosystem
Telecom Subscriber Insights aligns with the Google Cloud “data-to-AI” stack: – Data ingestion → Pub/Sub / Dataflow / Storage Transfer / partner tools – Storage and analytics → BigQuery + Cloud Storage – Governance → Dataplex, IAM, Cloud Logging – BI → Looker / Looker Studio – ML/AI → BigQuery ML / Vertex AI – Operations → Cloud Monitoring, Logging, alerting, SLOs
3. Why use Telecom Subscriber Insights?
Business reasons
- Reduce churn by identifying high-risk cohorts earlier (tenure + complaints + poor experience signals).
- Improve ARPU and retention by targeting offers using behavior and usage patterns.
- Improve customer experience by correlating network performance and customer outcomes.
- Faster time to insight by standardizing how subscriber data is modeled and accessed.
Technical reasons
- Consolidation of analytics into a governed warehouse (often BigQuery) reduces duplicated marts.
- Scalable analytics: BigQuery supports very large datasets and many concurrent users.
- SQL-first: Many telecom analytics workloads can be expressed in SQL and automated.
Operational reasons
- Repeatable pipelines: ingestion + transformation + scheduled refresh supports consistent KPIs.
- Observability: central logging/monitoring supports operational reliability of data products.
- Self-service: business teams can explore governed datasets via BI tools.
Security/compliance reasons
- Subscriber datasets commonly include PII and sometimes regulated data. Google Cloud provides:
- Fine-grained access control (IAM, row/column-level security in BigQuery—verify the best current approach in docs)
- Audit logs (Cloud Audit Logs)
- Encryption at rest and in transit by default; CMEK options for many services
- DLP tooling to discover/classify sensitive data (Cloud DLP)
Scalability/performance reasons
- BigQuery is designed for large-scale analytics and can separate storage from compute.
- Partitioning/clustering and good modeling patterns can keep query costs and latency manageable.
When teams should choose it
Choose Telecom Subscriber Insights when you need: – A subscriber-centric analytics platform spanning multiple systems – A governed “single view” approach rather than siloed reporting – A path to integrate ML-driven churn/propensity into standard analytics workflows
When teams should not choose it
Avoid (or delay) this approach when: – You only need basic reporting and already have clean, unified datasets elsewhere – You lack data ownership/quality readiness (no stable subscriber IDs, poor event quality, missing data contracts) – You cannot meet compliance requirements for moving/exporting subscriber data into a cloud environment (consider hybrid patterns, data residency constraints, or confidential computing approaches; verify feasibility with compliance and Google Cloud guidance)
4. Where is Telecom Subscriber Insights used?

5. Top Use Cases and Scenarios
Below are realistic scenarios where Telecom Subscriber Insights patterns are applied. Each includes the problem, why it fits, and a short scenario.
-
Churn early warning dashboard – Problem: Retention teams learn about churn too late (after port-out or cancellation). – Why this fits: Aggregates usage, complaints, experience KPIs, and tenure into a churn risk view. – Example: Daily churn risk table in BigQuery plus Looker dashboard for “top at-risk subscribers by region and plan.”
-
Experience-to-outcome correlation – Problem: Network teams track KPIs (latency, drops) but can’t link them to churn or NPS. – Why this fits: Joins network telemetry/quality metrics to subscriber outcomes. – Example: Identify cells/regions where high dropped-call rate correlates with churn spikes in the following week.
-
Next-best-offer segmentation – Problem: Offers are generic and not personalized; campaigns underperform. – Why this fits: Uses subscriber usage patterns and plan/device info to segment. – Example: Heavy data users on capped plans receive targeted upgrade offers.
-
Customer care prioritization – Problem: Contact centers treat all tickets similarly; high-value customers churn after repeated issues. – Why this fits: Combines ARPU/value tiers with complaint history and experience signals. – Example: Automatically prioritize cases where a high-value subscriber had 3+ complaints and poor network experience.
-
Onboarding and early-life churn prevention – Problem: New subscribers churn in first 30–90 days due to setup issues or poor experience. – Why this fits: Tracks early usage, app activation, and first-week quality metrics. – Example: Trigger proactive support for subscribers who never complete app activation and show low usage.
-
Roaming and travel behavior insights – Problem: Roaming usage spikes create bill shock and dissatisfaction. – Why this fits: Aggregates roaming usage events and plan entitlements. – Example: Identify roaming-heavy segments and recommend travel add-ons before bill shock occurs.
-
Device and network capability analytics – Problem: Device mix affects network performance and feature adoption (5G, VoLTE). – Why this fits: Joins device attributes with network events and subscriber satisfaction. – Example: Determine which device models correlate with higher drop rates in certain bands/regions.
-
Fraud and anomalous usage patterns (supporting use case) – Problem: Unusual usage patterns may indicate SIM swap, account takeover, or abuse. – Why this fits: Centralized behavioral analytics can highlight anomalies (often combined with dedicated fraud systems). – Example: Alert on sudden usage spikes for a subscriber after SIM change plus multiple failed logins.
-
Revenue and ARPU cohort analysis – Problem: Finance and product teams can’t reliably measure ARPU trends by segment. – Why this fits: Builds consistent subscriber cohort and revenue metric tables. – Example: Monthly ARPU by tenure cohort and plan type with drill-down.
-
Marketing attribution and campaign measurement – Problem: Campaign impact is unclear because data is split across platforms. – Why this fits: Joins marketing exposures, subscriber actions, and outcomes. – Example: Measure churn reduction among subscribers exposed to retention offers vs control cohort.
-
SLA/experience reporting for enterprise accounts – Problem: Enterprise customers demand reliable reporting on service experience. – Why this fits: Creates account/subscriber rollups and consistent KPIs. – Example: Monthly experience summary for enterprise-managed lines with incident correlation.
-
Data product standardization across lines of business – Problem: Each team builds its own “subscriber table,” causing metric drift. – Why this fits: Promotes standardized curated datasets and governance. – Example: A single curated subscriber dimension and event model reused by care, marketing, and network teams.
6. Core Features
Because Telecom Subscriber Insights is an Industry solutions offering, “features” are best described as solution capabilities delivered through Google Cloud services and patterns. The exact packaged assets (schemas, dashboards, notebooks) may vary—verify in official docs.
1) Subscriber-centric data modeling
- What it does: Establishes a consistent subscriber entity (keys, attributes, relationships) and models key facts (usage, complaints, experience).
- Why it matters: Without consistent identity and dimensional modeling, every report redefines “subscriber” differently.
- Practical benefit: Faster analytics development and fewer KPI disputes.
- Caveats: Identity resolution is hard; you may need deterministic keys (account ID/MSISDN/IMSI) and rules for merges/splits.
2) Multi-source ingestion (batch and streaming)
- What it does: Brings data from OSS/BSS, CDRs, CRM, network telemetry, app events, and tickets into a cloud landing zone.
- Why it matters: Subscriber insights require joining signals across domains.
- Practical benefit: A single place to run analytics and build KPIs.
- Caveats: Source system constraints (file drops, CDC availability, latency) often define what is possible.
3) Scalable analytics warehouse (commonly BigQuery)
- What it does: Stores curated datasets and supports large-scale SQL analytics.
- Why it matters: Telecom datasets are large (events, CDRs, telemetry).
- Practical benefit: Interactive analytics and scheduled transformations.
- Caveats: Cost and performance depend on partitioning, clustering, and query design.
4) Near-real-time dashboards (optional)
- What it does: Enables dashboards updated on frequent intervals (minutes) when streaming pipelines are used.
- Why it matters: Some operational decisions need fast refresh (outages, campaign monitoring).
- Practical benefit: Faster detection of churn spikes or experience degradation.
- Caveats: Streaming adds operational complexity (late events, deduplication, backpressure).
5) BI and semantic layer (Looker / Looker Studio)
- What it does: Provides curated metrics, governed exploration, and dashboards.
- Why it matters: Subscriber insights must be consumable by non-engineering users.
- Practical benefit: Self-service exploration under governance.
- Caveats: Looker is typically licensed; Looker Studio is easier to start but has different governance/semantic capabilities.
6) ML-based churn/propensity modeling (BigQuery ML / Vertex AI)
- What it does: Builds predictive models using subscriber features.
- Why it matters: Predictive insights can prioritize retention actions.
- Practical benefit: Score subscribers daily/weekly and measure lift.
- Caveats: Models require careful feature engineering, bias checks, and monitoring; data leakage is a common risk.
7) Governance and data discovery (Dataplex/Data Catalog capabilities)
- What it does: Helps catalog datasets, manage data domains, and apply policies (implementation depends on your platform setup).
- Why it matters: Subscriber data is sensitive and shared across teams.
- Practical benefit: Better control, lineage understanding, and reuse.
- Caveats: Governance requires process adoption, not just tools.
8) Security controls for sensitive subscriber data
- What it does: Implements least privilege, audit logging, encryption controls, and optionally egress restrictions.
- Why it matters: Telecom data often includes PII and may be regulated.
- Practical benefit: Reduced breach risk and improved compliance posture.
- Caveats: Security is end-to-end; misconfigured exports, overly broad IAM, and unmanaged service accounts are common issues.
7. Architecture and How It Works
High-level architecture
A typical Telecom Subscriber Insights implementation on Google Cloud has these layers:
- Sources: BSS (billing), CRM, OSS, CDRs, network KPIs, trouble tickets, app events
- Ingestion: batch file loads and/or streaming ingestion
- Landing zone: Cloud Storage (raw files), BigQuery raw tables
- Processing/curation: transformations to curated subscriber-centric schemas
- Serving: BI dashboards, curated views, ML feature tables, prediction outputs
- Governance/security: IAM, audit logs, data classification, encryption keys, perimeters
- Operations: monitoring, alerting, cost controls, data quality checks
Request/data/control flow (typical)
- Data arrives from source systems (files, streams, CDC).
- Pipelines validate, standardize, and load into raw storage/tables.
- Transformations create curated dimensions/facts and aggregated features.
- BI tools query curated datasets; ML training and scoring jobs read curated feature tables.
- Governance and security policies restrict access and track audit logs.
Integrations with related Google Cloud services (common)
- BigQuery: analytics warehouse, scheduled queries, BI Engine (where applicable), BigQuery ML
- Cloud Storage: raw landing, archives, exports/imports
- Pub/Sub + Dataflow: streaming ingestion and transformation (optional)
- Dataplex: data governance and domain management (verify current recommended setup)
- Cloud DLP: PII discovery/masking workflows
- Vertex AI: model training/registry/prediction (optional)
- Cloud Logging/Monitoring: pipeline and platform observability
- Cloud KMS: customer-managed encryption keys (where required)
Dependency services
There is no single “Telecom Subscriber Insights runtime.” Your deployment depends on:
– BigQuery and any pipelines/tools you choose
– Storage and network controls
– IAM, org policy, and governance tooling
Security/authentication model
- Users authenticate via Google identity (Cloud Identity / Workspace / federated identity).
- Service-to-service access is handled via service accounts and IAM roles.
- Fine-grained data access is controlled through BigQuery permissions and dataset/table policies.
Networking model
- Many Google Cloud data services are accessed via Google APIs.
- For higher-security environments you may use:
- Private access patterns (for example, Private Google Access / PSC where applicable—verify per service)
- VPC Service Controls to reduce data exfiltration risk
Monitoring/logging/governance considerations
- Centralize audit and platform logs in a dedicated logging project.
- Track pipeline health (job failures, lag, SLAs).
- Track data quality (freshness, null rates, uniqueness of subscriber IDs).
- Use labels/tags for cost allocation by domain (marketing, care, network).

8. Prerequisites
Because Telecom Subscriber Insights is implemented using multiple Google Cloud services, prerequisites are the prerequisites of the underlying services you will deploy.
Account/project requirements
- A Google Cloud account and a Google Cloud project
- Billing enabled on the project (BigQuery and other services require billing)
Permissions / IAM roles (minimum for the lab in this tutorial)
For the hands-on lab (BigQuery-only implementation), you typically need:
– roles/bigquery.admin (or a combination of dataset create + job run permissions)
– roles/serviceusage.serviceUsageAdmin (to enable APIs)
– roles/resourcemanager.projectIamAdmin is not required for the lab, but is often used by admins
In a real production implementation, use least privilege (see Security and Best Practices).
Tools needed
- A modern browser for Google Cloud Console
- Cloud Shell (recommended) or local installation of:
gcloudCLIbqCLI (included with Cloud SDK)
APIs to enable (lab)
- BigQuery API: https://console.cloud.google.com/apis/library/bigquery.googleapis.com
Optional for broader implementations (not required in this lab): – Cloud Storage API – Dataflow API – Pub/Sub API – Vertex AI API – Cloud DLP API
Region availability
- BigQuery datasets have a location (US/EU/region).
- Choose a dataset location you can keep consistent with other resources.
Quotas/limits (high-level)
- BigQuery has quotas for query jobs, load jobs, and more.
- BigQuery ML has limits and costs tied to the queries/jobs executed.
- For official limits, verify: https://cloud.google.com/bigquery/quotas
Prerequisite services (conceptual)
For production Telecom Subscriber Insights you often need: – A data ingestion mechanism from each source system – Data governance and privacy controls appropriate to your regulatory environment
9. Pricing / Cost
Pricing model (what you actually pay for)
Telecom Subscriber Insights, as an Industry solutions offering, does not typically have a single public “per-hour” price in the way a standalone compute service does. Costs come from the Google Cloud services you use to implement it, plus potential licensing (for example Looker).
You should treat the pricing model as the sum of: – BigQuery (storage + queries + optional reservations) – Data ingestion/processing (Dataflow, Pub/Sub, etc., if used) – Storage (Cloud Storage) – BI (Looker licensing or Looker Studio usage) – ML (BigQuery ML/Vertex AI compute) – Monitoring/logging volumes (Cloud Logging ingestion/retention beyond free allotments)
Official pricing pages (start here)
- BigQuery pricing: https://cloud.google.com/bigquery/pricing
- BigQuery ML overview (costs follow BigQuery jobs/queries): https://cloud.google.com/bigquery/docs/bqml-introduction
- Cloud Storage pricing: https://cloud.google.com/storage/pricing
- Dataflow pricing (if used): https://cloud.google.com/dataflow/pricing
- Pub/Sub pricing (if used): https://cloud.google.com/pubsub/pricing
- Looker (licensing model varies; verify current details): https://cloud.google.com/looker
- Pricing Calculator: https://cloud.google.com/products/calculator
Pricing dimensions (typical)
BigQuery – Query processing (on-demand per data processed, or flat-rate/reservations) – Storage (active and long-term) – Streaming inserts (if you use streaming ingestion paths; verify latest pricing as it can change)
Dataflow (if used) – Worker compute time (vCPU, memory) – Persistent disk usage – Streaming engine (if used)
Pub/Sub (if used) – Message volume – Retention and egress patterns
Looker – Contract/license based (edition and users). Not a simple per-GB metric.
Major cost drivers
- Raw event volume (CDRs/telemetry/app events can be enormous)
- Frequency of refresh (hourly vs daily vs near-real-time)
- Number of BI users and dashboard query patterns
- Model training/scoring frequency and feature complexity
- Data retention duration (raw + curated + aggregates)
- Cross-region data movement and egress
Hidden or indirect costs
- Cloud Logging ingestion and retention for high-volume pipelines
- Data egress if you export results outside Google Cloud or across regions
- Duplicate storage (raw + curated + aggregates + backups)
- Development environments (multiple projects replicate baseline costs)
- Third-party ingestion tools (licenses)
Network/data transfer implications
- Keep data and compute in the same region/location where possible.
- Avoid exporting large datasets out of BigQuery; use authorized views or in-place sharing patterns where appropriate.
- If you must move data across regions for compliance or operations, estimate egress carefully.
How to optimize cost (practical checklist)
- Partition and cluster BigQuery tables (especially time-series events).
- Use scheduled aggregations and materialized views for commonly used KPIs.
- Restrict BI dashboards to curated aggregate tables, not raw events.
- Use BigQuery reservations (flat-rate) if you have predictable, high query volume.
- Use dataset-level access controls to reduce accidental “SELECT *” scans.
- Set budgets and alerts; consider BigQuery query cost controls and limits where appropriate (verify current admin options in BigQuery).
Example low-cost starter estimate (no fabricated prices)
A low-cost proof of concept usually includes: – A small BigQuery dataset (MBs to a few GB) – A few scheduled queries per day – Looker Studio dashboards (often no additional license cost) – Minimal logging
Cost is primarily driven by BigQuery query processing and storage. Use the Google Cloud Pricing Calculator and the BigQuery pricing page for your region and expected query volume.
Example production cost considerations
Production implementations often include: – Continuous ingestion of high-volume events (CDRs/network KPIs) – Multiple curated layers (raw/bronze, refined/silver, serving/gold) – Many BI users and frequent dashboard refresh – Several ML models retrained and scored regularly – Compliance-grade security controls and audit retention
In production, it is common to evaluate: – BigQuery on-demand vs reservations – Whether streaming is required or batch is sufficient – How long raw data must be retained online vs archived to cheaper storage
10. Step-by-Step Hands-On Tutorial
This lab does not assume a hidden “Telecom Subscriber Insights API.” Instead, it builds a minimal, realistic subscriber insights workflow using BigQuery (core to many Telecom Subscriber Insights implementations): unified subscriber table → feature engineering → churn model with BigQuery ML → a table ready for dashboards.
Objective
Build a small subscriber analytics dataset in BigQuery and train a churn prediction model using BigQuery ML—producing a churn_scores table you can visualize in Looker Studio.
Lab Overview
You will:
1. Create a BigQuery dataset for the lab
2. Generate synthetic subscriber and monthly usage/experience data directly in BigQuery
3. Build a curated “subscriber features” table
4. Train and evaluate a BigQuery ML logistic regression model for churn
5. Score subscribers and create a churn_scores table
6. (Optional) Connect Looker Studio to the scored table
7. Clean up resources
Expected outcome: At the end, you will have a working, low-cost example of the core analytics + ML loop behind Telecom Subscriber Insights patterns.
Step 1: Create or select a Google Cloud project and open Cloud Shell
- In Google Cloud Console, select (or create) a project.
- Open Cloud Shell.
Set environment variables:
export PROJECT_ID="$(gcloud config get-value project)"
export BQ_LOCATION="US" # Choose US or EU, keep consistent for the lab
export DATASET="tsi_lab"
Enable the BigQuery API:
gcloud services enable bigquery.googleapis.com
Expected outcome: BigQuery API is enabled for the project.
Verify:
gcloud services list --enabled --filter="name:bigquery.googleapis.com"
Step 2: Create a BigQuery dataset
Create the dataset in your chosen location:
bq --location="$BQ_LOCATION" mk -d \
--description "Telecom Subscriber Insights lab dataset" \
"$PROJECT_ID:$DATASET"
Expected outcome: A dataset named tsi_lab exists.
Verify:
bq ls --datasets
Step 3: Create and populate a synthetic subscribers table
Run the following SQL to create a subscriber dimension with basic attributes and a churn label.
bq query --location="$BQ_LOCATION" --use_legacy_sql=false "
CREATE OR REPLACE TABLE \`$PROJECT_ID.$DATASET.subscribers\` AS
WITH base AS (
SELECT
subscriber_id,
18 + CAST(FLOOR(RAND() * 55) AS INT64) AS age,
1 + CAST(FLOOR(RAND() * 72) AS INT64) AS tenure_months,
CASE
WHEN RAND() < 0.45 THEN 'prepaid'
WHEN RAND() < 0.90 THEN 'postpaid'
ELSE 'business'
END AS plan_type,
CASE
WHEN RAND() < 0.25 THEN 'north'
WHEN RAND() < 0.50 THEN 'south'
WHEN RAND() < 0.75 THEN 'east'
ELSE 'west'
END AS region
FROM UNNEST(GENERATE_ARRAY(1, 5000)) AS subscriber_id
),
labeled AS (
SELECT
*,
-- Synthetic churn label: higher churn tendency for low tenure, prepaid, and certain regions.
CASE
WHEN tenure_months < 6 AND plan_type = 'prepaid' AND RAND() < 0.30 THEN 1
WHEN tenure_months < 12 AND RAND() < 0.12 THEN 1
WHEN plan_type = 'business' AND RAND() < 0.03 THEN 1
ELSE 0
END AS is_churned
FROM base
)
SELECT * FROM labeled;
"
Expected outcome: subscribers table exists with 5,000 rows.
Verify:
bq query --location="$BQ_LOCATION" --use_legacy_sql=false "
SELECT
COUNT(*) AS subscribers,
AVG(is_churned) AS churn_rate
FROM \`$PROJECT_ID.$DATASET.subscribers\`;
"
Step 4: Create and populate a synthetic monthly usage + experience table
Create a table that resembles monthly subscriber usage and experience signals (data usage, voice minutes, dropped calls, complaints, latency).
bq query --location="$BQ_LOCATION" --use_legacy_sql=false "
CREATE OR REPLACE TABLE \`$PROJECT_ID.$DATASET.monthly_usage\` AS
WITH months AS (
SELECT month
FROM UNNEST(GENERATE_DATE_ARRAY(DATE_SUB(CURRENT_DATE(), INTERVAL 5 MONTH), CURRENT_DATE(), INTERVAL 1 MONTH)) AS month
),
grid AS (
SELECT s.subscriber_id, m.month, s.plan_type, s.region, s.tenure_months
FROM \`$PROJECT_ID.$DATASET.subscribers\` s
CROSS JOIN months m
),
signals AS (
SELECT
subscriber_id,
month,
-- Synthetic usage:
CASE
WHEN plan_type = 'business' THEN 25 + RAND() * 60
WHEN plan_type = 'postpaid' THEN 10 + RAND() * 40
ELSE 2 + RAND() * 15
END AS data_gb,
CASE
WHEN plan_type = 'business' THEN 400 + RAND() * 800
WHEN plan_type = 'postpaid' THEN 200 + RAND() * 500
ELSE 50 + RAND() * 250
END AS voice_minutes,
-- Experience signals:
CAST(FLOOR(RAND() * 12) AS INT64) AS dropped_calls,
CAST(FLOOR(RAND() * 3) AS INT64) AS complaints,
-- Latency varies by region:
CASE
WHEN region IN ('north','east') THEN 35 + RAND() * 60
ELSE 50 + RAND() * 90
END AS avg_latency_ms
FROM grid
)
SELECT * FROM signals;
"
Expected outcome: monthly_usage exists with roughly 5000 subscribers * 6 months = ~30000 rows.
Verify:
bq query --location="$BQ_LOCATION" --use_legacy_sql=false "
SELECT
COUNT(*) AS rows,
MIN(month) AS min_month,
MAX(month) AS max_month
FROM \`$PROJECT_ID.$DATASET.monthly_usage\`;
"
Step 5: Build a curated subscriber_features table
This table aggregates usage and experience signals into features you can use for churn modeling and dashboards.
bq query --location="$BQ_LOCATION" --use_legacy_sql=false "
CREATE OR REPLACE TABLE \`$PROJECT_ID.$DATASET.subscriber_features\` AS
WITH agg AS (
SELECT
subscriber_id,
AVG(data_gb) AS avg_data_gb,
AVG(voice_minutes) AS avg_voice_minutes,
AVG(dropped_calls) AS avg_dropped_calls,
AVG(complaints) AS avg_complaints,
AVG(avg_latency_ms) AS avg_latency_ms,
-- Recent month emphasis:
MAX_BY(data_gb, month) AS last_data_gb,
MAX_BY(dropped_calls, month) AS last_dropped_calls,
MAX_BY(complaints, month) AS last_complaints,
MAX_BY(avg_latency_ms, month) AS last_latency_ms
FROM \`$PROJECT_ID.$DATASET.monthly_usage\`
GROUP BY subscriber_id
)
SELECT
s.subscriber_id,
s.age,
s.tenure_months,
s.plan_type,
s.region,
agg.* EXCEPT (subscriber_id),
s.is_churned
FROM \`$PROJECT_ID.$DATASET.subscribers\` s
JOIN agg
USING (subscriber_id);
"
Expected outcome: A single feature table with one row per subscriber.
Verify:
bq query --location="$BQ_LOCATION" --use_legacy_sql=false "
SELECT
COUNT(*) AS rows,
COUNTIF(is_churned=1) AS churned
FROM \`$PROJECT_ID.$DATASET.subscriber_features\`;
"
Step 6: Train a churn model with BigQuery ML
Train a logistic regression model. This uses is_churned as the label.
bq query --location="$BQ_LOCATION" --use_legacy_sql=false "
CREATE OR REPLACE MODEL \`$PROJECT_ID.$DATASET.churn_model\`
OPTIONS(
model_type='logistic_reg',
input_label_cols=['is_churned'],
data_split_method='AUTO_SPLIT'
) AS
SELECT

avg_latency_ms,
last_data_gb,
last_dropped_calls,
last_complaints,
last_latency_ms,
is_churned
FROM \`$PROJECT_ID.$DATASET.subscriber_features\`;
"
Expected outcome: Model churn_model exists.
Verify model creation:
bq ls "$PROJECT_ID:$DATASET"
Evaluate the model:
bq query --location="$BQ_LOCATION" --use_legacy_sql=false "
SELECT *
FROM ML.EVALUATE(MODEL \`$PROJECT_ID.$DATASET.churn_model\`);
"
Expected outcome: Metrics such as accuracy, precision, recall, log_loss, roc_auc (availability depends on BigQuery ML’s evaluation output for your model and version).
Step 7: Score subscribers and create a churn_scores table
Create a table with churn probability for each subscriber.
bq query --location="$BQ_LOCATION" --use_legacy_sql=false "
CREATE OR REPLACE TABLE \`$PROJECT_ID.$DATASET.churn_scores\` AS
SELECT
subscriber_id,
predicted_is_churned,
predicted_is_churned_probs[OFFSET(1)].prob AS churn_probability

avg_latency_ms,
last_data_gb,
last_dropped_calls,
last_complaints,
last_latency_ms
FROM \`$PROJECT_ID.$DATASET.subscriber_features\`
)
);
"
Expected outcome: churn_scores table exists with one row per subscriber.
Verify:
bq query --location="$BQ_LOCATION" --use_legacy_sql=false "
SELECT *
FROM \`$PROJECT_ID.$DATASET.churn_scores\`
ORDER BY churn_probability DESC
LIMIT 20;
"
Step 8 (Optional): Visualize churn risk in Looker Studio
Looker Studio can connect directly to BigQuery.
- Open Looker Studio: https://lookerstudio.google.com/
- Create a new report → Add data → BigQuery
- Select your project → dataset
tsi_lab→ tablechurn_scores - Add a table chart showing:
–
subscriber_id–churn_probability– Sort descending - Optionally join/blend with
subscriber_featuresfor slicing byplan_typeandregion.
Expected outcome: A simple churn leaderboard and segmentation cuts by plan/region.
Validation
Run these checks:
- Row counts consistent
bq query --location="$BQ_LOCATION" --use_legacy_sql=false "
SELECT
(SELECT COUNT(*) FROM \`$PROJECT_ID.$DATASET.subscribers\`) AS subscribers,
(SELECT COUNT(*) FROM \`$PROJECT_ID.$DATASET.subscriber_features\`) AS feature_rows,
(SELECT COUNT(*) FROM \`$PROJECT_ID.$DATASET.churn_scores\`) AS score_rows;
"
- Churn probability within [0,1]
bq query --location="$BQ_LOCATION" --use_legacy_sql=false "
SELECT
MIN(churn_probability) AS min_p,
MAX(churn_probability) AS max_p
FROM \`$PROJECT_ID.$DATASET.churn_scores\`;
"
- Basic business cut
bq query --location="$BQ_LOCATION" --use_legacy_sql=false "
SELECT
f.plan_type,
f.region,
AVG(s.churn_probability) AS avg_churn_probability
FROM \`$PROJECT_ID.$DATASET.subscriber_features\` f
JOIN \`$PROJECT_ID.$DATASET.churn_scores\` s
USING (subscriber_id)
GROUP BY 1,2
ORDER BY avg_churn_probability DESC;
"
Troubleshooting
Issue: “Access Denied: BigQuery BigQuery: Permission denied” – Ensure your user has permissions to create datasets and run jobs. – Minimum for the lab: BigQuery admin or equivalent.
Issue: “Not found: Dataset … was not found in location …”
– BigQuery datasets have a location (US/EU/region).
– Always pass --location="$BQ_LOCATION" and keep it consistent.
Issue: Model training fails or is slow – Reduce data size (for example generate 1,000 subscribers instead of 5,000). – Avoid overly complex queries during training.
Issue: Costs higher than expected – Avoid repeatedly rerunning training queries. – Review bytes processed in query details. – Use smaller synthetic tables while learning.
Issue: Looker Studio can’t see the table – Confirm you are logged into the same Google account. – Confirm you selected the correct project. – Confirm BigQuery permissions include viewing the dataset/tables.
Cleanup
To delete everything created in this lab, delete the dataset (this removes tables and the model):
bq rm -r -f "$PROJECT_ID:$DATASET"
Optionally, disable the BigQuery API (usually not necessary):
gcloud services disable bigquery.googleapis.com
If you created a dedicated project for the lab, consider deleting the project to ensure complete cleanup.
11. Best Practices
Architecture best practices
- Design for domains: separate raw/curated/serving layers and document contracts between them.
- Use a canonical subscriber key strategy: define how you map identities (account ID, MSISDN, IMSI) and handle changes.
- Model facts and dimensions: subscriber dimension + event/usage facts; avoid “one giant table” for everything.
- Separate compute from storage: keep raw data in Cloud Storage and curated analytics in BigQuery where appropriate.
- Plan for late arriving data: especially with network telemetry and CDR pipelines.
IAM/security best practices
- Enforce least privilege: separate roles for ingestion, transformation, BI consumption, and administration.
- Prefer group-based access rather than granting users direct dataset access.
- Use service accounts per pipeline with narrowly scoped permissions.
- Consider row/column-level security for PII access patterns (verify current BigQuery recommended method).
- Use CMEK where policy requires it and ensure key rotation processes exist.
Cost best practices
- Partition time-series tables (for example by event_date or month).
- Cluster by high-cardinality fields used in filters/joins (subscriber_id, region, plan).
- Create aggregate “gold” tables for dashboards and limit BI access to them.
- Use scheduled queries to precompute expensive metrics.
- Monitor query bytes processed and set budgets/alerts.
Performance best practices
- Avoid
SELECT *on large event tables in dashboards. - Use approximate aggregations when exact counts are not required.
- Denormalize carefully: sometimes helpful for BI; avoid uncontrolled duplication.
Reliability best practices
- Treat data pipelines like production services:
- retries, idempotency, deduplication keys
- backfills and replay capability
- clear runbooks and on-call ownership
- Define data SLAs (freshness, completeness) and monitor them.
Operations best practices
- Centralize logs/metrics for pipelines and BigQuery jobs where possible.
- Implement data quality checks (nulls, uniqueness, referential integrity).
- Use consistent naming:
- datasets:
raw_*,curated_*,serving_* - tables:
dim_*,fact_*,agg_*,features_* - Label resources with cost center, environment, owner, and data domain.
Governance/tagging/naming best practices
- Maintain a data catalog with owners, descriptions, and classifications for every dataset/table.
- Classify PII fields and restrict exports.
- Establish a retention policy (raw vs curated) aligned with legal/compliance needs.
12. Security Considerations
Identity and access model
- Humans: authenticate via Google identity; access controlled via IAM and group membership.
- Workloads: use service accounts; avoid using user credentials in automation.
Recommended patterns: – Separate projects (or at least datasets) for: – raw ingestion – curated analytics – consumption/BI – Use dedicated service accounts for: – ingestion pipelines – transformations – ML training/scoring – exports/activation jobs
Encryption
- Google Cloud encrypts data at rest and in transit by default.
- If required, use Customer-Managed Encryption Keys (CMEK) via Cloud KMS for supported services.
- Ensure key access is restricted and audited.
Network exposure
- Many workflows use Google APIs; limit public exposure by:
- restricting who can create exports
- using org policy constraints
- using VPC Service Controls in sensitive environments (verify service compatibility)
Secrets handling
- Do not store database passwords or API keys in code or notebooks.
- Use Secret Manager for secrets (if you integrate external systems).
- Prefer workload identity / service account auth where possible.
Audit/logging
- Enable and retain Cloud Audit Logs appropriate for your compliance needs.
- Monitor:
- dataset permission changes
- unusual query patterns
- large exports
- creation of external connections
Compliance considerations
- Subscriber data often contains:
- PII (names, addresses, phone numbers)
- account identifiers
- location or usage metadata (potentially sensitive)
- Engage your compliance team early for:
- data residency requirements
- retention rules
- access logging requirements
- third-party sharing controls
Common security mistakes
- Granting
roles/bigquery.adminbroadly to analysts - Putting PII in “shared” datasets without row/column controls
- Allowing unrestricted export to Cloud Storage buckets with weak IAM
- Using one shared service account for all pipelines
- Not monitoring BigQuery job history for unexpected large scans/exports
Secure deployment recommendations
- Use least privilege roles and separate environments (dev/test/prod).
- Apply organization policies and standardized project templates.
- Use data classification and DLP scanning where appropriate.
- Implement egress controls when handling highly sensitive data.
13. Limitations and Gotchas
Because Telecom Subscriber Insights is a solution composed of multiple services, limitations are typically implementation limitations rather than a single product quota.
Known limitations (practical)
- Identity resolution complexity: subscriber identifiers can change; merges/splits are non-trivial.
- Data quality: inconsistent timestamps, missing fields, and duplicates can break KPIs and models.
- Streaming complexity: deduplication, late events, and ordering require careful design.
- BI performance: dashboards that query raw event tables can be slow and expensive.
Quotas and limits
- BigQuery quotas apply (queries, load jobs, concurrency). See: https://cloud.google.com/bigquery/quotas
- If you use Dataflow/Pub/Sub, their quotas apply too (verify per service).
Regional constraints
- BigQuery dataset location must align with your compliance and with other resources.
- Cross-region joins or frequent data movement increases cost and complexity.
Pricing surprises
- Dashboard refreshes can trigger frequent BigQuery scans.
- Re-training models repeatedly during experimentation can increase query costs.
- Raw retention can drive storage growth.
Compatibility issues
- Source systems may not support efficient CDC; batch file exports may be the only option.
- Some telco data formats (CDRs) require specialized parsing/normalization.
Operational gotchas
- Without data contracts and ownership, pipelines become fragile.
- Backfill strategy is often ignored until an outage occurs—define it early.
- Schema drift from source exports can break loads and transformations.
Migration challenges
- Migrating from legacy EDW/reporting can expose differences in KPI definitions.
- Reproducing “exactly the same” metrics may require careful reconciliation and stakeholder alignment.
Vendor-specific nuances
- Telecom Subscriber Insights is best treated as a Google Cloud solution pattern; verify which parts are productized vs reference-only in current official materials.
14. Comparison with Alternatives
Telecom Subscriber Insights is a subscriber analytics solution approach. Alternatives include using individual platform components directly, competing cloud solutions, or self-managed stacks.
| Option | Best For | Strengths | Weaknesses | When to Choose |
|---|---|---|---|---|
| Telecom Subscriber Insights (Google Cloud) | Telecom teams wanting a subscriber-centric analytics solution pattern on Google Cloud | Aligns architecture to telecom outcomes; leverages BigQuery/Looker/ML; strong governance/security options | Not a single turnkey API; requires integration work and data engineering | When you want a reference architecture and a coherent GCP-based approach to subscriber analytics |
| BigQuery + Looker (DIY on Google Cloud) | Teams that already know their data model and just need scalable analytics | Maximum flexibility; use best-fit services; can start small | More design effort; harder to standardize without a solution blueprint | When you have strong platform engineering capability and clear requirements |
| Vertex AI-centric custom ML platform | ML-heavy orgs prioritizing advanced modeling | Advanced ML ops and model lifecycle tools | More complexity; still requires curated data foundation | When churn/propensity is the primary deliverable and you can invest in MLOps |
| AWS analytics stack (Glue/Athena/Redshift/QuickSight) | Organizations standardized on AWS | Mature service ecosystem; many ingestion options | Different operational model; migration effort; governance differs | When existing enterprise strategy is AWS-first |
| Azure analytics stack (Data Factory/Synapse/Fabric/Power BI) | Organizations standardized on Microsoft | Strong BI integration with Power BI; broad enterprise adoption | Different cost/perf characteristics; migration effort | When Azure/Power BI is the enterprise standard |
| Self-managed (Kafka + Spark + Trino + Superset) | Teams needing full control or on-prem/hybrid constraints | Maximum control; portable; can run on-prem | High ops burden; scaling and security are harder; time-to-value slower | When cloud constraints exist or you need deep customization and accept operational overhead |
15. Real-World Example
Enterprise telecom example (large operator)
Problem
A national operator has separate teams for network performance, customer care, and marketing. Churn increased in specific regions, but teams cannot correlate churn with network experience and ticket patterns due to siloed data.
Proposed architecture
– Raw data landing in Cloud Storage for:
– billing extracts
– CRM snapshots
– CDR files
– ticket exports
– Network KPIs ingested more frequently (streaming or micro-batch) into BigQuery
– Curated BigQuery datasets:
– dim_subscriber, dim_device, dim_plan
– fact_usage, fact_network_experience, fact_tickets
– Feature tables in BigQuery for churn and experience models
– Looker semantic model for consistent KPIs across departments
– Governance via Dataplex, strict IAM, DLP classification for PII, and audit retention
– Activation exports (aggregates/scores) back to CRM/campaign tools
Why Telecom Subscriber Insights was chosen – Provides a telecom-focused blueprint and helps align stakeholders around subscriber-centric modeling. – Uses Google Cloud services that scale with telecom volumes.
Expected outcomes – Faster identification of churn drivers by region/device/plan – Standardized metrics across departments – Improved retention targeting and measurable churn reduction – Reduced time to produce weekly/monthly executive dashboards
Startup / small-team example (MVNO or digital-first provider)
Problem
A small MVNO has limited data engineering capacity. They want churn insights and basic segmentation using exports from their CRM and billing provider.
Proposed architecture – BigQuery as the central analytics store – Daily batch loads (CSV extracts) into BigQuery – Scheduled queries build curated subscriber and usage aggregates – BigQuery ML churn model trained weekly – Looker Studio dashboard for churn risk and segment performance
Why Telecom Subscriber Insights was chosen – Guides a pragmatic, staged approach: unify data first, then add ML and dashboards. – Keeps operations lightweight by using managed services and SQL-first workflows.
Expected outcomes – A small set of actionable churn cohorts – Better understanding of early-life churn – Low operational overhead compared to self-managed stacks
16. FAQ
-
Is Telecom Subscriber Insights a standalone Google Cloud product with its own API?
Telecom Subscriber Insights is typically positioned as an Industry solutions offering (a solution approach using multiple Google Cloud services). It may not have a single dedicated API like BigQuery does. Verify the current productization and assets in official Google Cloud materials. -
What Google Cloud services are most commonly used to implement Telecom Subscriber Insights?
Common building blocks include BigQuery, Cloud Storage, ingestion/processing services (often Pub/Sub and Dataflow), BI tools (Looker or Looker Studio), governance (Dataplex), and optionally BigQuery ML/Vertex AI. -
Can I implement this without streaming data?
Yes. Many subscriber analytics workloads work well with daily/hourly batch processing, especially for churn and segmentation. Streaming is useful for near-real-time operational dashboards and rapid anomaly detection. -
What’s the recommended place to store curated subscriber analytics tables?
BigQuery is a typical choice for curated analytics and feature tables due to its scalability and SQL support. -
How do I handle multiple subscriber identifiers (MSISDN/IMSI/account ID)?
Define a canonical subscriber key and maintain mapping tables. Document rules for merges/splits and effective dates. This is a foundational data modeling task. -
How do I protect PII in subscriber datasets?
Use least-privilege IAM, restrict dataset access, consider column-level protections, use DLP classification/masking workflows, and tightly control exports. For highly sensitive environments, consider VPC Service Controls (verify compatibility). -
Does BigQuery ML replace Vertex AI?
Not exactly. BigQuery ML is great for SQL-first modeling close to your data warehouse. Vertex AI is better for advanced ML workflows, custom training, and full MLOps. Many organizations use both. -
What is the fastest way to deliver value in a POC?
Start with a curated subscriber table + a small set of KPIs (churn rate, complaints, experience KPIs) and one model (simple churn risk). Avoid boiling the ocean with every source system. -
How do I keep dashboard costs under control?
Use aggregate serving tables, limit access to raw events, partition tables, and control refresh frequency. Monitor query bytes processed and set budgets/alerts. -
Can Looker Studio be used instead of Looker?
Looker Studio is good for lightweight dashboards and quick starts. Looker provides stronger governed semantics and enterprise capabilities, but licensing applies. Choose based on governance needs and scale. -
How do I measure whether churn modeling is actually helping?
Use proper experimentation: holdout/control groups, lift measurement, and time-based validation. Track not just model metrics but business outcomes. -
What are the biggest implementation risks?
Identity resolution, data quality, unclear KPI definitions, and insufficient security/governance for PII. -
How do I handle late-arriving CDRs or network events?
Use event-time partitioning where possible, define watermarking/backfill logic, and implement deduplication keys. -
Is there a “standard telecom data model” I can reuse?
Telecom data models vary by operator and systems. Some solutions may provide reference schemas; verify current official assets and adapt carefully to your environment. -
What should I do first: governance or dashboards?
Do both in parallel at a small scale: establish minimal governance (owners, access controls, classifications) while delivering a first dashboard. Governance that starts after broad sharing is much harder to retrofit. -
How do I operationalize churn scores into CRM actions?
Export scores/segments to your activation system (CRM/campaign tool) on a schedule, with strict access control and audit logging. Ensure consistent subscriber IDs and clear refresh semantics.

23. Summary
Telecom Subscriber Insights (Google Cloud, Industry solutions) is a solution approach for building subscriber-centric analytics—unifying telecom data sources, creating curated subscriber models, and enabling dashboards and ML-driven actions such as churn prevention.
It matters because telecom organizations need reliable, governed insights that connect subscriber behavior and experience with business outcomes. In Google Cloud, this is commonly implemented with BigQuery for analytics, optional ingestion and processing services for batch/streaming pipelines, BI tooling (Looker/Looker Studio), and ML options (BigQuery ML/Vertex AI), all wrapped with governance and security controls appropriate for sensitive subscriber data.
Key points to remember:
– Cost is driven mainly by BigQuery query patterns, data volume, refresh frequency, and BI usage—optimize with partitions, aggregates, and governance.
– Security must be end-to-end: least privilege IAM, PII controls, auditing, and careful export governance.
– When to use it: when you need a scalable subscriber analytics foundation and a clear path to operational insights and churn/propensity modeling on Google Cloud.
Next learning step: Take the lab in this tutorial and extend it into a multi-layer dataset (raw → curated → serving), then add governance controls and a scheduled scoring pipeline—mirroring a production Telecom Subscriber Insights implementation.
