摘要： A control plane (CP) function for mobility management may receive, from a user equipment (UE), a message which indicates a registration request for registration to a network slice. The CP function may select, as an allowed slice ID, a first slice ID of a first network slice in which to register the UE. The first slice ID has a slice/service type (SST) value indicating an SST and a first slice differentiator (SD) value associated with a first level of service to be provided. The CP function may alternatively select, as the allowed slice ID, a second slice ID of a second network slice in which to register the UE based on unavailability of the slice type associated with the first level of service. The second slice ID has the SST value indicating the slice type and a second SD value associated with a second level of service to be provided.

摘要： Presented herein are techniques to provide data session continuity for parallel data sessions involving a multiple Universal Subscriber Identity Module (MUSIM) user equipment (UE). In one example, a method may include obtaining an indication that session continuity for a first session associated with a first data network and a first USIM of a UE is allowed with respect to a second USIM in which the UE communicates first traffic for the first session via the first USIM. The method may further include determining that second traffic for a second session is to be communicated via the second USIM of the UE and, based on the indication that session continuity for the first session is allowed with respect to the second USIM, providing service information to the UE for the first session to enable the UE to communicate both the first traffic and the second traffic via the second USIM.

摘要： Provided herein are techniques to facilitate location-specific wireless local area network (WLAN) offload restrictions for user equipment based on wireless wide area network (WWAN) radio band(s). In at least one example, a method performed by an authentication server of a WLAN may include, for a user equipment (UE) that is connected to an NR radio band of a WWAN and is seeking to connect to the WLAN, querying a subscription element of the WWAN to obtain a location indicator and an NR radio band indicator for the UE; determining, based on the location indicator and the NR radio band indicator, whether the UE is allowed or required to offload to the WLAN; and based on determining that the UE is allowed to offload from the WWAN to the WLAN, facilitating a WLAN association response message to be sent to the UE for offloading the UE to the WLAN.
