Abstract:
A performance monitoring system and method is based on a Detailed Call Record (DCR). A DCR contains records of events occurring in different network domains ( 14, 20, 40 ) that are related to a single, specific VoLTE call. The DCR events for each VoLTE call cover all legs of the call, and for each call leg, the relevant events are ordered by time. A DCR also contains basic information to identify the call: the IMS Charging Identifier (ICID), the International Mobile Subscriber Identity (IMSI) of all involved subscribers, and the start and stop timestamps of the call. A DCR has all the relevant user plane measurement, radio measurement, and control plane data from all the involved domains ( 14, 20, 40 ) for all call legs of a VoLTE call, in contrast to prior art systems that focus only on a single subscriber's activities for a given call. The DCR thus provides a complete view of the call, allowing more complete analytics and troubleshooting. Furthermore, the data are collected and assembled automatically, with results available real-time, or with a few seconds delay.

Claim (Index 40):
The method of  claim 26  wherein correlating the data across all legs of the call, using the common identifier, to generate a DCR comprises:\n extracting events related to voice calls by determining the start and end timestamp of the call for each leg, and selecting every event between the timestamps; \n assigning an IMS Charging Identifier (ICID) to voice call events; and \n after detecting a termination message for the last leg of the call, assembling the extracted and identified events for each leg into a DCR.
