8.1 Application plane

8.1.1 IOPS MC user identity (IOPS MC ID)

8.1.1.1 General

The IOPS MC ID is used for identifying an MC user in the IOPS mode of operation. The IOPS MC ID uniquely identifies an MC user on the IOPS MC system.

The IOPS MC ID can be used for the user authentication with the IOPS MC system.

NOTE: The specific security and authentication mechanisms required in order to use the IOPS MC user identity need to be specified by SA3.

Editor’s Note: Adding reference to the IOPS user authentication procedure in SA3 TS is FFS.

8.1.2 IOPS MC service user identity (IOPS MC service ID)

8.1.2.1 General

The IOPS MC service ID is a unique identifier within the MC service that represents the MC service user in the IOPS mode of operation. The IOPS MC service ID is the IOPS MCPTT ID for the MCPTT service as defined in 3GPP TS 23.379 [5], and is the IOPS MCData ID for the MCData service as defined in 3GPP TS 23.282 [6].

NOTE: MCVideo service as defined in 3GPP TS 23.281 [10] is not supported in the current release.

8.1.3 IOPS MC service group identity (IOPS MC service group ID)

8.1.3.1 General

An IOPS MC service group ID is used for identifying an MC service group in the IOPS mode of operation. The MC service UE is able to make one or more MC service communications (as per the group configuration) with other member UEs whose users are within the same IOPS MC service group ID.

The general description of an MC service group ID is provided in 3GPP TS 23.280 [3].

8.1.3.2 IOPS MC service group ID management (IP connectivity functionality)

Figure 8.1.3.2-1 illustrates how the IOPS MC service group ID and the IOPS group IP multicast address are mapped to each other for the support of the IP connectivity functionality. The IOPS group IP multicast address is pre-configured in the MC service UEs supporting the IOPS mode of operation in accordance with the IOPS MC service group ID.

NOTE: The association between the IOPS MC service group ID and the IOPS group IP multicast address may be pre-defined in the MC services UEs.
