Section: 8.72 MBMS Flow Identifier
Content: The MBMS Flow Identifier is defined in 3GPP TS 23.246[ Multimedia Broadcast/Multicast Service (MBMS); Architecture and functional description ]  [37]. In broadcast mode, the MBMS Flow Identifier information element is included in MBMS Session Management messages to differentiate the different sub-sessions of an MBMS user service (identified by the TMGI) providing location-dependent content. The payload shall be encoded as per the MBMS-Flow-Identifier AVP defined in 3GPP TS 29.061[ Interworking between the Public Land Mobile Network (PLMN) supporting packet based services and Packet Data Networks (PDN) ]  [38], excluding the AVP Header fields (as defined in IETF RFC 3588 [39], clause 4.1).
