Abstract: An access and mobility management function receives, from a session management function, a request to set up a communication with a wireless device for transmitting downlink data. The access and mobility management function sends, based on the request, to the base station, a first paging message for a closed access group (CAG) wireless device that is allowed to access CAG cells. The first paging message indicates transitioning the CAG wireless device from an idle state to a connected state. The first paging message comprises a parameter indicating whether the wireless device is allowed to access non-CAG cells.

Abstract: A policy and charging control function (PCF) receives, from a session management function (SMF), a request for policy information of a wireless device, the request comprising a parameter of a time sensitive networking (TSN) bridge, wherein the parameter comprises port information of the TSN bridge. The PCF sends, to the SMF, a response to the request, the response comprising the policy information of the wireless device.

Abstract: A base station transmits, to a wireless device, at least one first radio resource control message comprising configuration parameters for a first session associated with a first session identifier between the wireless device and a user plane function and a second session associated with a second session identifier different from the first session identifier, for packet duplication of the first session, between the wireless device and the user plane function. The base station transmits, to the wireless device, at least one second radio resource control message indicating activation of the packet duplication. Based on the activation of the packet duplication, the base station receives original packets via the first session associated with the user plane function and duplicated packets of the first session via the second session.

Abstract: A session management function (SMF) receives, from a wireless device, an indication that an always-on packet data unit (PDU) session is requested. The SMF determines to establish the PDU session as an always-on PDU session based on: the indication that the always-on PDU session is requested; and the PDU session being for an ultra-reliable low-latency communication (URLLC) service. The SMF sends, to the wireless device, an indication that the PDU session is to be established as the always-on PDU session.

Abstract: A home session management function (SMF) of a home public land mobile network (PLMN) receives, from a visited SMF of a visited PLMN from a visited SMF of a visited PLMN, a request for creation of a packet data unit (PDU) session of a wireless device. The request comprises first charging policy information determined based on a first policy of the visited PLMN. The home SMF sends, to the visited SMF and based on the request, a second charging policy information comprising: a charging method for the PDU session; and a charging parameter indicating a charging level for the PDU session.

Abstract: A session management function (SMF) receives, from a wireless device, a first message requesting establishment of a PDU session for a network slice associated with a service of a communication service provider (CSP). The first message comprises a single network slice selection assistance information (S-NSSAI) of the network slice and a CSP identifier (ID). The SMF sends, to the wireless device, a second message accepting the establishment of the PDU session for the network slice associated with the service of the CSP.

Abstract: A multiple universal subscriber identity module (multi-USIM) wireless device sends, to a mobility management function, a registration request message comprising an indication for a paging cause value in a paging message. The wireless device receives a first paging message comprising the paging cause value. The wireless device sends, based on the first paging message, a radio resource control (RRC) message requesting a connection setup.

Abstract: 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.

Abstract: A wireless device may receive to a message requesting a connection setup (e.g., a paging message) via a first access technology (e.g., a 3GPP access technology) from a first wireless network. The wireless device may respond to the message by sending a response message via a second access technology (e.g., a non-3GPP access technology). The wireless device may send the response message to indicate that the wireless device does not accept the connection setup request.

Abstract: A device may include a processor configured to maintain a plurality of session management entities (SMEs) for a core network associated with a radio access network (RAN). The processor may be further configured to establish a communication session using a first SME, of the plurality of SMEs; store session data for the communication session in a communication session database accessible by each of the plurality of SMEs; receive, using a second SME of the plurality of SMEs, a message associated with the communication session; retrieve, using the second SME, session data for the communication session from the communication session database, based on receiving the message; and process, using the second SME, the message using the retrieved session data.

Abstract: Wireless communications are described for network assisted connection. A wireless device may send an indication of a multi-access packet data unit (PDU) session capability. A computing device may send (e.g., based on the indication) an indication to the wireless device to modify a single-access PDU session to a multi-access PDU session.

Abstract: A method can include transmitting, by a base station to a wireless device, a radio resource control (RRC) message to transition the wireless device from an RRC connected state to an RRC inactive state. The RRC message can indicate a time period in which the wireless device is reachable by paging. The RRC message can be configured to trigger the wireless device to transition from the RRC connected state to the RRC inactive state while remaining in a connection management (CM) connected state. The RRC message can also trigger the wireless device to monitor, in the RRC inactive state, to receive a paging message during the time period after the transitioning. The RRC message can further trigger the wireless device to, in response to an expiration of the time period, stop the monitoring to receive the paging message.

Abstract: A session management function (SMF) receives, from a wireless device, an indication that an always-on packet data unit (PDU) session is requested. The SMF determines to establish the PDU session as an always-on PDU session based on: the indication that the always-on PDU session is requested; and the PDU session being for an ultra-reliable low-latency communication (URLLC) service. The SMF sends, to the wireless device, an indication that the PDU session is to be established as the always-on PDU session.

Abstract: An access and mobility management function (AMF) receives from a session management function (SMF) a first session configuration request message for a packet duplication of a first session between a user plane function (UPF) and a wireless device.

Abstract: 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 wireless device monitors to receive a paging message during the active time period after the transitioning. The wireless stops monitoring for the paging message in response to the expiration of the active time period.
