- NDR-Flags, Unsigned32, code 4508, section 7.3.17
- NDA-Flags, Unsigned32, code 4509, section 7.3.18
- User-Data-Id, Unsigned32, code 4510, section 7.3.19
- MC-Service-User-Profile-Data, Grouped, code 4511, section 7.3.20
- Sequence-Number-29.283, Unsigned32, code 4512, section 7.3.21
- Data, Grouped, code 4513, section 7.3.22
- MCVideo-ID, UTF8String, code 4514, section 7.3.24
- MCData-ID, UTF8String, code 4515, section 7.3.25
Note: Name conflict with 3GPP TS 29.140 Sequence-Number (1107).
and 3GPP TS 29.329 Sequence-Number (716).
3GPP TS 29.140 V6.1.0 (2005-06) allocated Sequence-Number (1107).
3GPP TS 29.329 V10.0.0 (2010-09) CR 0163 added Sequence-Number (716).
3GPP TS 29.283 V13.1.0 (2016-06) allocated Sequence-Number (4512).
Fix: Sequence-Number (4512) renamed to Sequence-Number-29.283 (4512).
