An access and mobility management function (AMF) receives, from a base station, a non-access stratum (NAS) request message of a wireless device comprising one or more single network slice selection assistance information(s) (S-NSSAIs) corresponding to one or more network slices. The AMF determines to perform network slice specific authentication and authorization (NSSAA) for a first network slice of the one or more network slices. The AMF sends, to the base station, based on the determining, an N2 setup message comprising an indication that the first network slice is pending.

Network slice specific authentication and authorization

A system may include a base station central unit and a base station distributed unit. The base station central unit may include one or more processors and memory storing instructions that, when executed by the one or more processors, cause the base station central unit to send, to the base station distributed unit, an indication that a cell is associated with a first non-public network (NPN); and to send, to the base station distributed unit, a request for configuration of the cell for a wireless device that supports the first NPN. The base station distributed unit may include one or more processors and memory storing instructions that, when executed by the one or more processors, cause the base station distributed unit to receive the indication and the request for configuration of the cell.

Non-public network indication and configuration of cell thereof

A user plane function (UPF) receives, from a control plane function (CPF), a request to establish a layer 2 tunneling protocol (L2TP) tunnel for a first protocol data unit (PDU) session of a wireless device. The UPF sends, to the CPF, a message comprising a tunnel failure cause for the establishment of the L2TP tunnel for the first PDU session. The message indicating at least one of a L2TP tunnel failure of the L2TP tunnel, or a L2TP session failure associated with the L2TP tunnel.

Tunnel failure signaling procedures

A wireless device receives, from a first network, one or more messages comprising an authentication and/or authorization (AA) status of the wireless device indicating whether the wireless device is authenticated and/or authorized for an aerial service, and a parameter indicating that an interface between the first network and a second network is not supported. The wireless device sends, to a network function of the second network, a message, wherein the message comprises the AA status based on the parameter indicating that there is no interface.

Aerial service

A method can include sending, by a wireless device to an access and mobility management function (AMF) a non-access stratum (NAS) message indicating a request to establish a packet data unit (PDU) session to join a group communication session. The NAS message can include an identifier of the group communication session, an identifier of a network slice, and a protocol configuration option information. The method can also include receiving, by the wireless device from the AMF, a response message indicating acceptance of the request.

Wireless device request for protocol data unit session

A first wireless device transmits, to a second wireless device, a discovery message comprising a non-public network (NPN) identifier of an NPN to which the first wireless device can provide access.

Relay node selection

Providing expandable network slices that may increase in geographic coverage area on-demand include includes enabling a user equipment device (UE) to operate on a network slice instance on a first Next Generation Node B (gNB) associated with a first cell in a 5G NR cellular network. While the UE is operating on the network slice instance, the system detects mobility of the UE that may require handover from the first gNB associated with the first cell on which the UE is operating to a second gNB associated with a second cell, in which the first gNB and second gNB belong to different tracking areas. While the UE is operating on the network slice instance, the system deploys and activates the same network slice instance on the second gNB that is associated with the second cell based on the detection of mobility of the UE.

Systems and methods for expandable network slices in a wireless telecommunication network

A first base station receives a first request to notify a change of a closed access group (CAG) area of a wireless device. The first base station sends, to an access and mobility management function (AMF), a location report message indicating the change of the CAG area of the wireless device.

Location reporting handling

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

A wireless device may be configured to perform a method including receiving, from a time sensitive network (TSN) translator device, a TSN parameter. The wireless device may also send, to an access and mobility management function (AMF), a non-access stratum (NAS) message indicating a request to establish a protocol data unit (PDU) session comprising the one or more TSN parameters. The wireless device may receive, from the AMF, a message indicating acceptance of the PDU session.

Wireless device related to time sensitive network for protocol data unit session establishment with access management function

A wireless device sends a first request to a mobility management function via a base station. The first request includes a paging cause indication in a paging message. A first paging message is received by the wireless device and comprises a first paging cause indication. Based on the first paging message, a second request for a connection setup is sent.
