摘要： A SMF receives from a first UPF, first message(s) indicating a status of the first UPF. The SMF determines, based on the status, to transfer sessions for a group of wireless devices from the first UPF to a second UPF. The SMF sends to the second UPF, a second message indicating an establishment request of sessions for the group of wireless devices. The second message comprises session identifiers of the sessions. The SMF receives from the second UPF, a third message indicating a result of the establishment request. The SMF sends to the first UPF, based on the result, a fourth message indicating release of session(s) of the sessions. The fourth message comprises session identifier(s) of the session(s).

摘要： A wireless device in an RRC connected state receives a radio resource control (RRC) message from a base station. The wireless device transitions from the RRC connected state to an RRC inactive station in response to the RRC message. The RRC message indicates an active time period in which the wireless device is reachable by paging. The wireless device monitors to receive a paging message during the active time period after the transitioning. The wireless device activates a mobile initiated communication only (MICO) mode in response to an expiration of the active time period. The wireless stops monitoring for the paging message in response to the expiration of the active time period.

摘要： A first base station receives, from a second base station, a message comprising a network slice configuration parameter associated with a closed access group that one or more cells of the second base station support. The first base station determines based on the network slice configuration parameter, a handover for the wireless device to a cell of the one or more cells. The first base station sends, to the second base station, a request message for the handover, the request message comprising an identifier of the closed access group of the wireless device.

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 session management function (SMF) receives a message from a network exposure function (NEF). The message comprises downlink data and a release assistance indicator (RAI). The RAI indicates that transmission of uplink data by a wireless device is expected subsequent to transmission of the downlink data. The RAI indicates a release of a connection associated with the wireless device after the transmission of uplink data. The SMF receives an indication that the uplink data is transmitted. The SMF upon receiving the indication, sends a release message to an access and mobility management function (AMF). The release message indicates release of a non-access stratum message associated with the wireless device. The release message comprises the release assistance indicator.

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