TD S2 160200 LS from CT WG1: LS on ProSe Group Management Parameters. (CT WG1)
Abstract: CT WG1 has been defining the content of the MCPTT Group Document in TS 24.381 and the MCPTT Group Management Object (MO) in TS 24.383 and has been considering the MCPTT Group configuration data defined in subclause 10.1.5.4 and in Annex B.4 of TS 23.179v13.0.0 and the interaction with ProSe for off network operation. Subclause 10.1.5.4 and table B.4-3 of TS 23.179 define the following ProSe related parameters: - associated relay service code (as specified in 3GPP TS 23.303 [8]); - ProSe Layer-2 Group ID (optional) (as specified in 3GPP TS 23.303 [8]); - ProSe Group IP multicast address (optional) (as specified in 3GPP TS 23.303 [8]); - indication whether the UE should use IPv4 or IPv6 for that MCPTT group (optional) (as specified in 3GPP TS 23.303 [8]). (This is not included in Annex B). - User Info Id (as specified in 3GPP TS 23.303 [8]); (This is called 'ProSe user info id' in table B.4-3) Based on this CT WG1 intend to define elements for these in the MCPTT Group Document in TS 24.381 for online configuration and in a corresponding MCPTT Group MO in TS 24.383 for offline configuration. In addition to the ProSe Layer-2 Group ID CT WG1 also intend to include 'ProSe Discovery Group-ID' within the MCPTT Group Document and MCPTT Group MO as this is understood to also be required. During discussion it was pointed out that the above parameters already exist in the ProSe MO in TS 24.333. CT WG1 make the assumption that duplication of these ProSe parameters in the MCPTT Group Document and MCPTT Group MO as well as in the ProSe MO is intended by SA WG6. This requires that the MCPTT service provider ensure that the parameters in these documents are all configured with the same values in order to ensure correct operation.
Convenors comment: Proposed to be noted as CC for SA WG2.
