Telecom operators face constant challenges in ensuring accurate reconciliation between core and intelligent network elements for preventing revenue leakage and ensuring seamless service delivery. During our recent webinar, Preventing Revenue Leakage: Core vs. Intelligent Network Reconciliation, we explored:
- The importance of reconciling data between core network elements (MSC, SMS-C, GGSN, SGSN) for revenue assurance.
- Common challenges encountered in Voice, SMS, and Data reconciliation.
- Practical demonstrations on reconciling data effectively between core network elements and the Intelligent Network (IN) to prevent revenue leakage and ensure data accuracy.
We also engaged in a vibrant Q&A session, addressing critical questions from participants. Here’s a recap of the key questions and our expert responses:
1. Why Don’t Postpaid Accounts Show on OCS in MSC vs OCS Reconciliation?
Answer: There are two scenarios:
- OCS manages both prepaid and postpaid accounts: In this case, OCS generates Call Detail Records (CDRs) for all accounts (prepaid, hybrid, postpaid), and these CDRs are reconciled with MSC data.
- OCS manages only prepaid and hybrid accounts: In this scenario, OCS doesn’t generate CDRs for postpaid accounts. Instead, another system (Offline Billing) collects postpaid CDRs directly from MSC for rating. The reconciliation process must include these rated records from Offline Billing to complete the reconciliation.
2. How to Handle Pay-As-You-Go (PAYG) and Bundles for Prepaid Accounts?
Answer: Prepaid subscribers their voice, SMS, and data usage can be charged as follows:
- PAYG (Pay-As-You-Go) charges are deducted from the main account for airtime.
- Free resources purchased via main account airtime or mobile money wallet.
For both scenarios the reconciliation process traces the sms, voice and data usages in both MSC and OCS. However, reconciling free resource usage vs. bundle purchased at the OCS level accuracy depends on how operators manage balances:
- If operators use separate balances for each bundle, the reconciliation process is straightforward and can verify the accuracy of the consumption of the bundle.
- If operators accumulate free resources from different bundles into a single balance, reconciliation becomes more complex.
3. How Do You Manage Different Operator File Structures in CDR Analysis Tools (e.g., Ericsson vs Huawei)?
Answer: The reconciliation process is designed to be scalable and vendor-agnostic. All vendor CDRs are mapped into a unified schema, ensuring compatibility and streamlined analysis across different systems.
4. How Can VoLTE Reconciliation Be Effectively Done?
Answer: VoLTE reconciliation involves challenges related to both voice and data portions of traffic. While a deep dive into this topic is planned for a dedicated webinar, initial considerations include correlating VoLTE data and voice records across network elements and billing systems.
5.Est-il possible d’identifier les numéros qui peuvent émettre des appels mais pas identifiés sur IN (ENG:Is It Possible to Identify Numbers That Can Make Calls but Are Not Registered on the IN?
Answer: Yes, it is possible. The reconciliation process must access Know Your Customer (KYC) data from CRM to enrich CDRs from both MSC and OCS. This enables filtering for non-identified subscribers engaging in traffic (voice, SMS, or data).
6. Comment détecter des numéros créés sur HLR et non sur IN (ENG:How Can We Detect Numbers Created on HLR but Not on IN?)
Answer: This can be achieved by reconciling dumps from HLR and OCS. By comparing these datasets, it’s possible to identify MSISDNs enabled on the HLR but not on the OCS.
7.Please can you guide us on how to effectively reconcile PGW vs OCS
Answer: The PGW usually generates a lot of intermediate CDRs with a unique correlation ID called the Charging ID, which is also reported in data charging CDRs from OCS. Effective reconciliation involves:
- Aggregating CDRs from PGW.
- Joining aggregated data with OCS records using MSISDN and Charging ID.
Key Takeaways from the Webinar
- Data reconciliation is essential for ensuring revenue assurance and preventing revenue leakage.
- Challenges vary across network elements, but scalable, vendor-agnostic solutions simplify the process.
- Accurate reconciliation requires enriching datasets with external information like KYC data.

The Importance of CDR Reconciliation between MSC and IN for Voice and SMS
Call Detail Records (CDRs) serve as a fundamental building block for tracking, billing, and analyzing various communication services like voice calls and SMS. These records are generated by different network elements such as the Mobile Switching Center (MSC) and the Intelligent Network (IN). However, discrepancies between these records can lead to serious issues, including revenue leakage, fraud, and data inconsistencies. This blog post explores why CDR reconciliation between MSC and IN is crucial. it outlines how to perform reconciliation for voice and SMS services, highlights common challenges, and shows how big data tools like Apache Spark can streamline the process.
Why CDR Reconciliation is Important?
CDR reconciliation is not just a technical exercise; it is a crucial component of an effective revenue assurance process. Ensuring that all CDRs from different network nodes match perfectly is essential for several reasons. From maximizing revenue capture to ensuring compliance, a reliable reconciliation process can prevent numerous issues that telecom operators face on a daily basis. Let’s delve into the key reasons why this process is indispensable:
- Revenue Assurance: Reconciliation ensures that all billable events are captured and billed correctly. Discrepancies between MSC and IN CDRs can lead to revenue leakage, where services are provided but not billed accurately.
- Financial Integrity: Reconciliation validates the consistency of call records across different network elements, ensuring that the data used for billing, analysis, and reporting is accurate, thereby safeguarding financial integrity.
- Operational Efficiency: Identifying missing or duplicate records during reconciliation helps in detecting errors in the network, such as incomplete calls or unbilled events, which could lead to potential revenue loss and operational inefficiencies.
- Regulatory Compliance: Telecom operators must often report accurate traffic data to regulatory authorities. CDR reconciliation helps in ensuring the accuracy of these reports, thereby meeting regulatory requirements and avoiding penalties.
Achieving CDR Reconciliation for Voice (MO) and SMS (MO)
Implementing an effective CDR reconciliation process requires a systematic approach to match records from MSC and IN. While the goal is to ensure that both sets of records align perfectly, the actual process involves several steps and considerations, especially when dealing with multiple fields like msisdn, imsi, caller, called, timestamp, and sometimes a unique correlation ID. Here’s how you can achieve a robust reconciliation process for voice and SMS services:
Reconciliation Process for Voice (MO) between MSC and IN:
- Identify Key Fields: The main fields to consider for reconciliation are msisdn, imsi, caller, called, timestamp, and a unique correlation ID.
- Intermediate CDRs Aggregation: MSC often generates intermediate CDRs for the same call, especially for long-duration calls that are split into smaller segments. These intermediate CDRs must be aggregated based on caller, called, and timestamp to create a complete call record before reconciling with IN CDRs.
- Unique Correlation ID: Ideally, there should be a unique identifier that links the CDRs from MSC and IN for the same call. This ID ensures that the call records can be matched accurately across the two systems.
- Timestamp Matching: In cases where a unique correlation ID is not available, we can use a combination of fields like caller, called, and timestamp to identify matching records. However, time differences between MSC and IN systems can pose challenges.
Reconciliation Process for SMS (MO) between MSC and IN:
- Identify Key Fields: Similar to voice, important fields for SMS reconciliation include msisdn, imsi, sender, receiver, timestamp, and a unique correlation ID (if available).
- Aggregation of Long SMS Messages: For SMS, particularly long messages that are split into multiple segments (e.g., concatenated SMS), it is important to aggregate these segments into a single CDR based on sender, receiver, and timestamp before proceeding with reconciliation. This ensures that the entire message is accounted for correctly, avoiding partial billing or data discrepancies.
- Matching Criteria: After aggregation, it is crucial to match the sender and receiver numbers along with the timestamp to accurately reconcile the SMS records between MSC and IN.
Challenges in CDR Reconciliation
Despite the critical need for CDR reconciliation, the process is often challenging. From the absence of a unique correlation ID to time discrepancies between different network elements, telecom operators often face significant obstacles in achieving accurate and consistent CDR reconciliation. Understanding these challenges is essential to developing strategies to mitigate them. Here are some of the most common issues faced during the reconciliation process:
- Lack of Unique Correlation ID: Many times, there is no unique correlation ID between MSC and IN, making it difficult to directly match the records. In such cases, using a combination of msisdn, caller, called, and timestamp becomes necessary.
- Intermediate CDRs for Voice Calls: For long-duration calls, MSC generates multiple intermediate CDRs. These need to be aggregated to form a single complete call record before any reconciliation can be performed with IN CDRs. Failure to do so can result in mismatches and inaccuracies.
- Segmented SMS Messages: Long SMS messages that are split into multiple segments must be aggregated before reconciliation. Missing or incomplete segments can lead to discrepancies between MSC and IN records.
- Time Difference Between MSC and IN: Even a slight time difference between the CDR generation in MSC and IN can cause mismatches. For instance, if the MSC and IN systems are not synchronized to the same time source, the same event may appear at slightly different times, complicating the reconciliation process.
- Handling Duplicate Records: Sometimes, multiple CDRs are generated for the same event, especially in cases of call setup failures or retries. These duplicates must be filtered out to avoid false discrepancies.
- High Data Volume: The large volume of CDRs generated daily in a telecom network can make reconciliation a resource-intensive and time-consuming process.
How Big Data Tools Like Apache Spark Can Help
With the rise of Big Data technologies, the telecom industry now has powerful tools to handle large-scale data reconciliation more efficiently. Apache Spark, in particular, stands out for its ability to process massive datasets in parallel, making it an excellent choice for CDR reconciliation. Leveraging Spark can not only speed up the reconciliation process but also provide additional capabilities like anomaly detection and real-time analytics. Here’s how Spark can transform the reconciliation process:
- Scalability and Speed: Spark can handle large volumes of data efficiently with its in-memory processing capabilities, making it ideal for processing millions of CDRs quickly.
- Distributed Processing: Spark’s distributed architecture allows it to parallelize the reconciliation process across multiple nodes, significantly speeding up the comparison of records from MSC and IN.

Ensuring Accuracy in Data Reconciliation between CGSN and IN for 2G/3G and 4G Networks
Introduction
Data usage records are logged by various network nodes, such as SGSN/GGSN in 2G/3G networks and SGW/PGW in 4G networks. These records, known as data session EDRs (Event Detail Records), capture critical information about data sessions, including the volume of data used, session duration, and charging details. Meanwhile, the Intelligent Network (IN) records the billing details associated with these data sessions. Reconciliation between between CGSN and IN sources is essential to ensure accuracy in billing, revenue assurance, and network management. In this blog post, we will explore the importance of reconciling these data records, the challenges involved, and how Big Data tools like Apache Spark can streamline this process.
Why Data Records Reconciliation is Important
- Accuracy in Data Billing: Each data session, whether in a 2G/3G or 4G network, must be accurately billed to the customer. Discrepancies between the volume of data recorded by the CGSN and the charges recorded by the IN can lead to billing errors, causing revenue loss and customer dissatisfaction.
- Revenue Assurance: Ensuring that all data usage is correctly captured and billed is crucial for preventing revenue leakage. Reconciliation helps identify missing, duplicated, or incorrect records, allowing operators to correct discrepancies proactively.
- Network Performance Monitoring: Reconciliation can also provide insights into network performance by comparing the expected usage (as recorded by SGSN/GGSN or SGW/PGW) with the actual charges. This helps operators in network planning and optimization.
How to Achieve Data Records Reconciliation between CGSN and IN?
- Matching Using MSISDN, IMSI, and Timestamp:
- MSISDN and IMSI are unique subscriber identifiers that link data sessions across network and billing systems.
- The timestamp is a crucial attribute that captures the start and end times of a session. Matching records based on MSISDN, IMSI, and timestamp helps in accurately linking data usage records from CGSN and IN.
- Using a Unique Correlation ID:
- Some systems generate a unique correlation ID for each data session, linking records between the network and billing nodes seamlessly. This ID makes reconciliation straightforward by directly associating each data session with its corresponding billing record.
- However, in many instances, this unique ID is not available, complicating the reconciliation process.
Challenges in Data Records Reconciliation?
- Absence of a Unique Correlation ID:
- When there is no unique ID linking records between CGSN and IN, operators must rely on MSISDN, IMSI, and timestamp for matching. This approach is prone to errors, especially when dealing with sessions that start and stop frequently or overlap.
- Time Synchronization Issues:
- Even a minor time discrepancy between SGSN/GGSN (or SGW/PGW) and IN can lead to unmatched records. These discrepancies can arise due to differences in system clocks, network delays, or processing times.
- To address this, operators often use a time window to match records, where sessions are considered correlated if their timestamps fall within a predefined range, such as ±10 seconds.
- Handling High Volumes of Intermediate Records:
- Data sessions often generate multiple intermediate records, especially during long or fragmented sessions. These records need to be consolidated into a single session record before reconciliation.
- For 4G networks, SGW/PGW may generate separate records for different parts of a session, further complicating the consolidation process.
Leveraging Big Data Tools for Efficient Reconciliation?
- Using Apache Spark:
- Apache Spark’s distributed processing capabilities are ideal for handling large volumes of data records from both CGSN and IN. It allows for efficient matching of records based on multiple keys like MSISDN, IMSI, and timestamp.
- Spark’s in-memory processing reduces latency, enabling near real-time reconciliation, which is critical for maintaining billing accuracy and revenue assurance.
- Consolidating Intermediate Records:
- Spark can aggregate multiple intermediate records into a single session based on MSISDN and IMSI, while applying business rules to filter out duplicates and handle overlaps.
- For example, all records with the same MSISDN and IMSI within a session can be grouped together, and their data volume and duration summed to create a consolidated record.
- Handling Time Differences:
- Spark’s window functions allow for flexible time-based grouping and aggregation. A time window can be defined to match records with slight timestamp differences, accounting for system clock discrepancies between CGSN and IN.
- This helps in accurately correlating records, even when exact timestamps do not match.
- Scaling with Data Growth:
- As data usage continues to grow, the volume of EDRs from SGSN/GGSN and SGW/PGW increases exponentially. Spark’s ability to scale horizontally by adding more nodes to the cluster ensures that reconciliation processes can keep pace with the growing data volumes without compromising performance.

Despite the challenges such as the absence of a unique correlation ID, time synchronization issues, and high volumes of intermediate records, big data tools like Apache Spark provide a robust solution. Spark’s distributed processing, in-memory computation, and advanced aggregation capabilities enable efficient and scalable reconciliation, ensuring data integrity and billing accuracy.
In the next blog post, we will provide a step-by-step guide on implementing a Spark-based data records reconciliation pipeline, complete with code examples and best practices. Stay tuned.
