System and method for associating IP services to mobile subscribers

摘要

A system and method for subscriber tracking and creating subscriber records in a GPRS or UMTS network is disclosed. A local mapping record is created on a probe monitoring a Gi interface upon the detection of Access Start messages. Additional information is sent from a probe monitoring a Gn/Gp interface, and this information is added to the local mapping record. The processing of captured messages and the creation of local mapping record is prioritized to ensure that records for different subscribers who used the same IP address are not improperly combined. Finally, Gi traffic is tagged with unique subscriber information, such as the International Mobile Subscriber Identity (IMSI), not previously present on the Gi network.
