External Session Tracking Performance Scenarios

This scenario mimics a simple SCC call. SRVCC is disabled, so no external session tracking occurs.

This scenario is identical to SCC-Simple - No SRVCC, except SRVCC is enabled, so external session tracking occurs when the call set-up is complete (message 7).

This scenario mimics a SCC call with provisional responses. SRVCC is disabled, so no external session tracking occurs.

This scenario is identical to SCC-Provisional - No SRVCC, except SRVCC is enabled, so external session tracking occurs twice; firstly when the 183 is received (Message 5/6) and again when the call set-up is complete (message 23).
