摘要： A wireless device receives configuration parameters from a base station. The configuration parameters are for a first session and a second session. The second session is for a packet duplication of the first session. The wireless device receives an activation indication of the packet duplication. Based on the activation indication of the packet duplication, the wireless device sends packets of the first session to a user plane function and a duplication of the packets to the user plane function via the second session.

摘要： An SMF receives from an AMF a PDU session create request message requesting establishment of a PDU session for a wireless device. In response to the PDU session create request message, the SMF sends to a CHF a charging policy request message requesting charging policy information for the PDU session. The SMF receives from the CHF a response message comprising the charging policy information for the PDU session. The charging policy information comprises a first charging method. Based on the charging policy information, the SMF determines a charging control rule for the PDU session. The SMF enforces the charging control rule.

摘要： An access and mobility management function (AMF) receives, from a network function, an event exposure subscribe message requesting to notify a change of closed access group (CAG) area of a wireless device. The AMF sends, to a base station, a location reporting control message requesting to notify the change of the CAG area of the wireless device. The location reporting control message comprises a list of CAG identifiers. The AMF receives, from a second base station, a location report message notifying the change of the CAG area. The AMF sends, to the network function, an event exposure notify message indicating the change of the CAG area.

摘要： A user plane function receives from a session management function, a first message requesting at least one quality of service (QoS) report for a data flow of a wireless device. The first message comprising: a first information element indicating a QoS event; and a second information element indicates a latency value for the QoS event. A user plane function sends to the wireless device, monitoring packets for monitoring a packet transmission latency of the data flow. The user plane function determines an occurrence of the QoS event based on the packet transmission latency of the data flow and the latency value. The user plane function sends to the session management function, a second message comprising a third information element indicating the occurrence of the QoS event for the data flow.

摘要： A wireless device sends to an access and mobility management function (AMF), a message comprising a time sensitive networking (TSN) bridge capability support parameter that indicates that the wireless device supports a TSN bridge functionality. The wireless device receives, from the AMF and based on the TSN bridge capability support parameter, a configuration update message comprising at least one route configuration rule. The wireless device sends, to the AMF, a request to establish a protocol data unit (PDU) session, the request comprising one or more configuration parameters determined based on the at least one route configuration rule.

摘要： An access and mobility management function (AMF) receives from a wireless device, a first message indicating a request for a group communication session. The first message comprises a group communication session identifier. The AMF selects a session management function (SMF) for the group communication session of the wireless device. The AMF sends to a unified data management function (UDM), a second message to create a group context information. The second message comprises the group communication session identifier and an identifier of the SMF associated with the group communication session identifier.

摘要： An application server sends a request message to a subscriber server indicating a first query for terminating access domain selection (T-ADS) information for an Internet protocol multimedia subsystem (IMS) session of a wireless device. The application server receives from the subscriber server, the T-ADS information comprising: a first wireless device IP address and a first network name of a first RAT for the IMS session, and a second wireless device IP address and a second network name of a second RAT. The application server determines an access network for the IMS session based on the first network name, the first wireless device IP address, the second network name and the second wireless device IP address. The access network is one of the first RAT or the second RAT. The application server sends an IMS message to the wireless device to setup the IMS session over the access network.

摘要： A wireless device sends a PDU session establishment request message to an access and mobility management function (AMF). The PDU session establishment request message requests establishment of a packet data unit (PDU) session for an always-on PDU session. The wireless device receives a first message from the AMF. The first message indicates at least one service associated with the always-on PDU session. The wireless device sends at least one packet of an at least one allowed service of the at least one service via the always-on PDU session.

摘要： A policy control function (PCF) receives a first message from an application function (AF). The first message comprises: an always-on PDU session requested indication; an identity of a wireless device; and application service information. The PCF maps, based on the first message, the application service information to an always-on PDU Session for the wireless device. The PCF sends to a session management function (SMF), at least one policy and charging rule for the always-on PDU Session.

摘要： An AMF sends a first request message to an NSSF for at least one network slice information for a wireless device. The AMF receives from the NSSF, location based network slice coexistence rule(s) for location(s) of the wireless device. The location based network slice coexistence rule(s) are for allowed network slice information that is a subset of the network slice information. The AMF receives from the wireless device being at a first location, a second request message for a first network slice for the wireless device. The AMF determines to accept the first network slice based on the first location and the location based network slice coexistence rule(s). The AMF sends to the wireless device, a first response message indicating acceptance of the first network slice.
