Stage 3 work may be needed for CT1 at a later stage.

3GPP TSG GERAN would like to inform 3GPP TSG CT WG1 and 3GPP TSG SA WG2 that it has approved a work item to manage MOCN supporting MSs/UEs in GERAN. See attached work item description in GP-110332.
3GPP TSG GERAN has already introduced support for network sharing for non-supporting MSs/UEs (i.e. only a Common PLMN is broadcast on the Radio Interface – a PLMN list is not broadcast). However, 3GPP TSG SA WG1 has asked 3GPP TSG GERAN to “ensure support for manual PLMN selection in GERAN network sharing scenarios”, which means that there is a requirement on the network to supply the terminals with information about the PLMN IDs of the different operators sharing the GERAN network. It also puts a requirement on terminals to be able to read this information, select one PLMN ID and inform the network about the selected PLMN ID. It is the understanding of TSG GERAN that such a requirement mandates the management of MOCN supporting MSs/UEs.
It has been realized during 3GPP TSG GERAN’s discussion that standardization of management of MOCN supporting MSs/UEs in GERAN includes stage 3 work for TS 24.008 under 3GPP TSG CT WG1’s responsibility as well as stage 2 work for TS 23.251 under 3GPP TSG SA WG2’s responsibility.
3GPP TSG GERAN would like to accomplish the good level of cooperation between the different working groups involved in the standardisation of management of MOCN supporting MSs/UEs in GERAN during the normative work in order to achieve complete alignment. In this respect and to allow 3GPP TSG CT WG1 and 3GPP TSG SA WG2 to achieve their own normative work, 3GPP TSG GERAN will update these groups on the progress of the normative work within 3GPP TSG GERAN.
