Symmetricom Helps to Resolve Revenue Leakage Issues for Mobile Service Providers : With Carrier Class NTP Services, Finance/Operations Can Improve Compliance with Revenue Assurance Targets and Reduce Revenue Leakage due to Internet Protocol/Call Detail Record Mismatches

Share Article

Symmetricom, Inc. (NASDAQ: SYMM), a worldwide leader in precise time and frequency technologies that accelerate the deployment and enable the management of next generation networks, today released a comprehensive suite of resource materials that explain issues related to revenue assurance processes and address the costly problem of revenue leakage. The information details how to improve IP/Call Detail Record (IPDR/CDR) reconciliation and thus potentially increase Average Revenue per User (APRU) by deploying high availability carrier class Network Time Protocol (NTP) for billing and logging services.

Revenue leakage is a major issue for mobile operators who typically put considerable effort into assuring service revenues

"Revenue leakage is a major issue for mobile operators who typically put considerable effort into assuring service revenues," said Danny Dicks, analyst at Innovation Observatory and a specialist on network billing and operations support system markets. "Addressing the root causes of incorrect detail records will improve charging and billing accuracy for all types of billable events, not just voice calls, and will reduce the volume of records that need to be dealt with as exceptions by the operator's billing team."

Mobile service providers can fail to capture all minutes from subscriber calls because their internal IP or Call Detail Record reconciliation process, or the arbitration/reconciliation between providers, is not optimized. This may impact the revenue assurance process and result in unpredictable revenue leakage with associated cost, ARPU, operational and tax implications. Little known to the service provider finance and marketing teams, one of the fundamental functions at the heart of logging, charging and billing architectures is a simple time service known as Network Time Protocol or NTP. Poor NTP architectures or poor installation of NTP services may be a direct cause of revenue leakage due to poor IPDR/CDR collection and collation. Correcting the problem is relatively simple and may have a positive ROI – measured in days – for many service providers.

NTP, designed to synchronize computer clocks over a network, is used to distribute and manage time services that control back office servers. A well engineered billing and logging system depends on accurate IPDR/CDR generation and reconciliation and, in turn, relies on a well structured time distribution model provided by a robust NTP service. Poorly architected or installed NTP services can interfere with the ability to deliver a reliable and accurate timestamp and the generation of consistent metrics over time. This can potentially lead to mismatches in logging chargeable network events and thus inaccurate logging and billing.

Deploying Symmetricom's carrier class NTP modules, designed to plug into ultra reliable and precise synchronization platforms (SSU/BITS) delivering hardware time-stamped carrier class NTP services, can significantly mitigate this problem. This may lead to reduced operational costs, improved profitability, fewer grounds for conflict with partners or customers, reduced time spent on manual back office reengineering, and ultimately, improved operational efficiencies.
