Figure 8.102-1: MBMS Flags
The following bits within Octet 5 indicate:
– Bit 1 – MSRI (MBMS Session Re-establishment Indication): if set to 1, this flag indicates that the MBMS Session Start Request message is used to re-establish an MBMS session (see 3GPP TS 23.007 [13])
– Bit 2 – LMRI (Local MBMS Bearer Context Release Indication): if set to 1, this flag indicates that the MBMS Session Stop Request message is used to release the MBMS Bearer Context locally in the MME/SGSN (see 3GPP TS 23.007 [13]);
– Bit 3 to 8 – Spare, for future use and set to zero.
