A base station includes a receiving unit that receives terminal capability from a terminal before a security procedure, and a control unit that eliminates the terminal capability acquired before the security procedure in response to a release of a terminal context related to the terminal.

Provided are a cell switching method and apparatus, a device, and a storage medium. The method includes the following. A first interface message is sent to a second network element, where the first interface message carries UE related information; a user context modification instruction triggered by the second network element is received, where the user context modification instruction is determined and triggered according to the first interface message, and the user context modification instruction is configured for triggering the handover of a target UE from a source cell to a target cell.

A second base station sends, to a wireless device, an indication of a data radio bearer (DRB) configured for a small data transmission (SDT) procedure of the wireless device. The second base station receives, from a first base station, a request for a context of the wireless device. The second base station sends, to the first base station, in response to the request, a response message indicating not to relocate the context of the wireless device, and the DRB configured for the SDT procedure. The second base station receives, from the first base station, downlink data forwarding information associated with the DRB configured for the SDT procedure. Based on the downlink data forwarding information, the second base station sends, to the first base station, downlink data of the SDT procedure received from a core network node.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a source master eNodeB (MeNB) may transmit, to a target Next Generation radio access network (NG-RAN) node, a handover required message to initiate an inter-system handover from an evolved-Universal Mobile Telecommunications System (UMTS) terrestrial radio access network (E-UTRAN) New Radio (NR) dual connectivity (EN-DC) system associated with the source MeNB to an NR standalone (SA) system associated with the target NG-RAN node. The source MeNB may have an indirect path to the target NG-RAN node and a source secondary gNodeB (SgNB) may have a direct path to the target NG-RAN node. The source MeNB may transmit, to the target NG-RAN node and based at least in part on the handover required message, forwarded data via the indirect path between the source MeNB and the target NG-RAN node through a core network. Numerous other aspects are described.

This disclosure describes a user equipment device (UE). The UE includes one or more antennas; one or more radios, where each of the radios is configured to perform cellular communication using a plurality of radio access technologies (RATs) that support voice over an Internet protocol (IP) multimedia subsystem (IMS); one or more processors coupled to the one or more radios, where the one or more processors are configured to cause the UE to perform operations including: sending, via a first RAT, a first request for IMS registration to an IMS server; receiving, from the IMS server, an IMS rejection message indicating failure of the IMS registration; determining, based on the IMS rejection message, that the IMS registration failure is temporary; responsively re-attempting IMS registration with the IMS server; and determining to camp on the first RAT in response to receiving an IMS acceptance message from the IMS server.

Systems, apparatuses, and methods are described for wireless communications. A base station and wireless device may communicate capability information associated with a wireless device. The capability information may include information indicating support for an Ethernet type packet data unit session or header parameter compression. An Ethernet type packet data unit session may be instantiated based on the capability information.

Provided is an information processing method and apparatus, a device and a storage medium. The information processing method includes: radio capability information is sent to a next generation NodeB (gNB); where the radio capability information includes user equipment (UE) capability information.

The present disclosure concerns managing mobility and emergency handling by receiving a mobility message from a second entity for managing access and mobility, wherein the mobility message carries a data network identifier for an IP connectivity; determining that the data network identifier in the received mobility message is an emergency data network identifier, based on emergency data network identifiers contained in emergency configuration data with which the first entity for managing access and mobility is configured; and determining that the IP connectivity is established for an emergency service.

The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting a higher data transmission rate. A method and a device for configuring data transmission are provided. The method includes transmitting a first message to a second node, the first message being used for the first node to provide configuration information for a user to the second node, or used for the first node to request the configuration information for the user from the second node, and/or receiving a second message from the second node, the second message being used for the second node to provide the configuration information for the user to the first node, or used for the second node to request the configuration information for the user from the first node, to avoid unnecessary signaling overhead.

A method in a network node includes receiving a radio resource control (RRC) connection reestablishment request from a user equipment (UE). The method includes generating a new Long identifier, ID, for the UE. The method includes determining whether a UE Context Fetch is successful. The method includes responsive to determining that the UE Context Fetch is not successful, determining whether a Long ID has been fetched. The method includes responsive to determining that the Long ID has been fetched, placing the Long ID that has been fetched in a UE Context Fetch Failure event.
