Abstract: A policy control function (PCF) receives from a session management function (SMF) a first message requesting policy establishment of a first packet data unit (PDU) session for a wireless device. The first message comprises a first single-network slice selection assistance information (S-NSSAI) and a first network slice instance identifier (NSI ID) for the first S-NSSAI. The PCF also receives a second message comprising an identifier of a communication service provider (CSP ID). The PCF maps the first NSI ID to the CSP ID and further selects a charging function (CHF) for the first PDU session per CSP based on the mapping.

The base station receives, from a wireless device, a connection request to access the first network via the second network. The base station sends, based on the indication, a rejection of the connection request.

Abstract: A wireless device may receive, from a base station of a network, an indication of whether the network performs time traceability to coordinated universal time (UTC). For example, the indication may indicate that the network does not perform time traceability to UTC. Based on the network not performing time traceability to UTC, the wireless device may implement time traceability to UTC.

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 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.

Abstract: A network repository function (NRF) receives, from an access and mobility management function (AMF), a discovery request for an address of a session management function (SMF), the discovery request comprising network slice isolation information for at least one network slice. The NRF sends, to the AMF and based on the discovery request, a discovery response comprising the address of the SMF.

Abstract: A wireless device sends, to a network, a message indicating an enhanced steering of roaming (SOR) capability for network access information for one or more non-public networks (NPN). The wireless device receives, from the network, network access information comprising an identifier of a first NPN and a condition for whether the wireless device is allowed to access the first NPN. The wireless device sends, to the first NPN and based on the condition being met, a registration request message.

Abstract: A wireless device may communicate with a base station via a cell. A cell may be selected for wireless communications based on having a configuration that is capable of serving certain wireless resources associated with a wireless device. A wireless device may select a cell that comprises a communication link supporting certain wireless resources that may be required for use by the wireless device.

Abstract: A base station central unit receives, from a base station distributed unit, configuration parameters of at least one periodic radio resource for packet transmissions of a wireless device in a radio resource control (RRC) inactive state or RRC idle state. The base station central unit sends, to the base station distributed unit, a wireless device context release message comprising an RRC release message and an indication that the base station distributed unit maintains the at least one periodic radio resource after the wireless device transitions to the RRC idle state or the RRC inactive state. The base station central unit receives, via the base station distributed unit, data from the wireless device while the wireless device is in the RRC inactive state or the RRC idle state.

Abstract: A base station may communicate with other base stations for handover decisions. Information about energy consumption of other base stations may be used by the base station for efficient handover decisions. Predictions of energy consumption may be exchanged before making a handover decision so that handover decisions may be based on energy usage.

Abstract: A base station may communicate with one or more other base stations. A first base station may hand over one or more wireless devices served by its cell to a second base station (e.g., a neighboring base station), for example, to save overall energy consumption in the network. Feedback information (e.g., one or more messages) associated with performance of the second base station after the handover may be provided by the second base station to the first base station help further decision-making related to handing over other wireless device(s).
