16.10.6.1 Session Management

For delivery of location dependent contents of a broadcast session, Area Session ID is included in the NGAP broadcast session resource setup procedure associated with MBS service area information and per Area Session ID NG-U tunnels are established.

If the 5GC detects shared NG-U path failure, it may notify the gNB and the gNB may allocate new shared NG-U resources to replace old ones as specified in TS 23.527 [69].

The 5GC may also provide information to the NG-RAN node whether the broadcast session is intended to be received by only (e)RedCap UEs, only UEs that are neither RedCap UEs nor eRedCap UEs or any kind of UEs. The NG-RAN may take this into account when configuring MBS session resources.
