Abstract: A method of enhanced manual network selection mode for access localized services in NPN is proposed. If an SNPN is available and included in the UE-stored configuration for SNPN selection, the UE presents to the user whether the SNPN is associated with validity information and whether the corresponding validity criteria are met. If a CAG cell in a PLMN broadcasting a CAG-ID is available and included in the (Allowed) CAG list of the UE-stored CAG related configuration of the PLMN, the UE presents to the user whether the CAG-ID is associated with validity information and whether the corresponding validity criteria are met, e.g., whether the CAG-ID is authorized based on the (Allowed) CAG list.

Abstract: A method of handling (alternative) IMSI value for MUSIM UEs supporting paging timing collision control in an EPS network is proposed. For a MUSIM UE and EPS supporting paging timing collision control, the MUSIM UE and the network can request and negotiate an IMSI offset for the IMSI value on one of the USIM card through a TAU or ATTACH procedure. When lower layer failure occurs, the network may not successfully receive a TRACKING AREA UPDATE COMPLETE (or ATTACH COMPLETE) message from the UE, and therefore the network may not know which IMSI value UE will use. Accordingly, the network needs to use both possible (alternative) IMSI values when deriving paging timing for the UE until one of the (alternative) IMSI values is considered invalid.
