CSCtn15437, CSCuo37725 - InTracer Support of SGSN - New requirement
Feature Changes
Intracer Support For 2G Calls
The IPMS (Intelligent Packet Monitoring System) solution provides a framework for operators to analyze and
investigate call related events for various platforms. The signaling messages related to 2G calls on SGSN are traced
through the IPMS. These include the message exchanges between SGSN and other peer entities like GGSN, HLR, EIR
and BSC.

and BSC.
A client server mechanism is implemented, where the IPMS client runs on the SGSN and copies the signaling packets
related to a 2G subscriber and then ships them to the IPMS server. This data can be used by operators in numerous ways
including debugging. Some identities like the IMSI, MSISDN, IMEI, APN, PDP addresses that are sent to the IPMS
server as and when they are learnt by the SGSN as standalone messages (TLVs) without any PDU. For example, during
a PTMSI attach procedure after the identity response from MS, the SGSN learns about the subscriber's IMSI and
