Abstract: A base station may communicate with at least one other base station to perform a handover of a wireless device. Predictions of a signal quality may be used for the handover of the wireless device. Predictions of signal quality may be included in a handover request message and/or in a handover response message. A determination of whether to proceed with a handover of the wireless device to a target base station may be based on the predictions of signal quality.

Abstract: A wireless device receives, from a first network via a second network, a first message comprising a first quality of service (QoS) parameter for a first protocol data unit (PDU) session of the wireless device with the first network, and an alternative QoS parameter for the first PDU session. The wireless device sends, to the second network and based on the first message, a second message comprising at least one of a second QoS parameter for the second PDU session based on the first QoS parameter and the alternative QoS parameter.

Abstract: A mobility management entity (MME) receives, from a wireless device, an attach request message indicating that the wireless device supports a first number of bearers. The MME selects a network gateway from a plurality of network gateways, based on a second number of bearers supported by the network gateway. The MME sends, to the network gateway, a create session request message for creating a session for the wireless device. The MME receives, from the network gateway, a create session response message confirming creation of the session.

Abstract: 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.

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.

The wireless device receives, from the base station, based on the indication of priority access, an RRC response message indicating an acceptance associated with the RRC request message.

Abstract: A base station of a first public land mobile network (PLMN) transmits, to a wireless device, an indication of a failure of a second PLMN comprising a PLMN identifier of the second PLMN. The base station receives, from the wireless device, a registration request indicating the failure of the second PLMN. The registration request comprises one or more of a subscriber concealed identifier (SUCI) or a permanent equipment identifier (PEI) of the wireless device. The registration request comprises the PLMN identifier of the second PLMN.

The base station transmits, to the wireless device, at least one second RRC parameter indicating that the wireless device is allowed to access a CAG of the one or more CAGs, wherein the at least one second RRC parameter comprises an identifier of the CAG. The base station receives a random access preamble via a cell associated with the CAG that the wireless device is allowed to access.

Abstract: A base station central unit, of a base station, comprises one or more processors and memory storing instructions. When executed by the one or more processors, the instructions cause the base station central unit to receive, from a base station distributed unit of the base station, height information of a cell; receive, from a wireless device, height information of the wireless device; send, to the base station distributed unit, based on the height information of the cell, an indication to configure the cell for the wireless device; receive, from the base station distributed unit, configuration parameters of the cell for the wireless device; and send, to the wireless device, the configuration parameters of the cell for the wireless device.

Abstract: A wireless device receives, from a base station, access network information. The wireless device determines, based on the access network information, an access network type. The wireless device selects, based on the access network type, a non-access stratum (NAS) period value from between a first NAS period value associated with a terrestrial network (TN) access network type; and a second NAS period value associated with a geostationary earth orbit (GEO) access network type. The wireless device sends, to an access and mobility management function (AMF), a first NAS request message. The wireless device starts, based on the sending the first NAS request message, a NAS period using the NAS period value.

Abstract: Systems, apparatuses, and methods are described for wireless communications. A base station and wireless device may communicate capability information associated with a wireless device.

Abstract: A session management function (SMF) sends a first message for user plane activation of a wireless device to an access and mobility management function (AMF), where the first message includes an identifier of a packet data unit (PDU) session of the wireless device and a subscriber permanent identifier (SUPI). The SMF receives a second message from the AMF in response to the wireless device being unreachable and determines an extended buffering time according to the second message. The SMF also sends a third message to a user plane function (UPF), where the third message includes the extended buffering time and an indication to buffer downlink data of the wireless device.

Abstract: Base station cell activation/deactivation may be based on energy cost. A base station may communicate with at least one other base station to coordinate deactivation of a cell and/or offloading one or more wireless devices in the cell to at least one other cell. Determination of additional energy cost and/or capability for serving the offloaded wireless device(s) may be made to calculate overall energy saving and/or to ensure uninterrupted connectivity in view of the deactivation. Base station communication may improve energy efficiency by performing deactivation/activation of one or more cells based on energy usage.

Abstract: A method may include receiving, by an access and mobility management function (AMF) from a core network node, a request message.

The method may also include sending, by the AMF to a base station, a location reporting request associated with altitude of the wireless device. The method may further include receiving, by the AMF, a location report associated with the altitude of the wireless device. The method may additionally include sending, by the AMF to the core network node, a report message notifying the altitude change of the wireless device.
