This TS provides the protocol details for the Flexible Alerting supplementary service in the IP Multimedia (IM) Core Network (CN) subsystem based on the requirements from TS 22.173.

Flexible Alerting (FA) causes a call to a pilot identity to branch the call into several legs to alert several termination addresses (group members) simultaneously. The first leg to be answered is connected to the calling party. The other call legs are abandoned.

This TS is applicable to User Equipment (UE) and Application Servers (AS) which are intended to support the FA supplementary service.
