An access and mobility management function (AMF) receives from a first wireless device a non-access stratum (NAS) message comprising an identifier (ID) of a group communication session. The AMF receives from a session management function (SMF) a message comprising a list of one or more second wireless devices associated with the group communication session and a list of one or more packet data unit (PDU) sessions. The AMF determines, based on a state of the one or more second wireless devices, to page the one or more second wireless devices. The AMF receives from the one or more second wireless devices one or more service request messages.

Group communication service request

A second base station sends to a first base station, a request for a context of a wireless device, wherein the request comprises assistance information for a small data transmission (SDT) procedure of the wireless device. The assistance information indicates whether single data associated with the SDT procedure is expected, or more than single data associated with the SDT procedure is expected.

Small data transmission assistance information

Wireless communications for network access configuration are described. A base station may configure a monitoring gap for a wireless device, based on information received from the wireless device. The wireless device may use the monitoring gap to communicate with another base station associated with another wireless network.

Wireless communications for network access configuration

A communication procedure may be used for multiple access. A wireless device may be capable of simultaneously accessing a plurality of networks that are associated with a visited network. The visited network may or may not allow the wireless device to simultaneously access the plurality of networks, for example, based on a status of the visited network. Prior to a wireless device requesting access to a plurality of networks, a visited network may indicate whether the visited network supports, for the wireless device, simultaneous access to a plurality of networks.

Multiple access

Embodiments provide novel approaches to handling network slice groups in access stratum and non-access stratum communications in a cellular communication network. Novel slice identification schema can support group-level identification of groups of network slices without individually listing the network slices. Some embodiments implement a slice identifier that supports wildcard slice/service type (SST) options and/or wildcard slice differentiator (SD) options to support wildcard-enabled slice groups. Some embodiments enable use of such wildcard-enabled slice groups in context of unified access control. Some embodiments introduce a novel criteria type to unified access control to expressly support flexible slice grouping.

Network slicing group
