    摘要： A base station may include one or more processors and memory storing instructions that, when executed by the one or more processors, cause the base station to perform a process. The process may include sending, to a wireless device, a radio resource control (RRC) message comprising at least one packet data convergence protocol (PDCP) configuration parameter indicating Ethernet header compression for a data radio bearer. The method may also include sending, to the wireless device, information associated with the Ethernet header compression. The information may include a source medium access control (MAC) address and a destination MAC address, as well as a header compression index corresponding to the source MAC address and the destination MAC address. The process may further include sending, to the wireless device, a compressed Ethernet packet comprising a packet header being compressed and the corresponding header compression index.

    摘要： A session management function (SMF) sends, to a first user plane function (UPF), a request to establish a layer 2 tunneling protocol (L2TP) tunnel between the UPF and a L2TP server for a first protocol data unit (PDU) session of a wireless device. The SMF receives, from the first UPF, a message indicating a failure of the L2TP tunnel, the message comprising a tunnel failure cause information element indicating at least one of a L2TP tunnel failure of the L2TP tunnel or a L2TP session failure associated with the L2TP tunnel.

    摘要： 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.

    摘要： A first base station receives, from a second base station, a next generation radio access network (NG-RAN) configuration update message including a neighbor information evolved universal mobile telecommunications system terrestrial radio access (E-UTRA) information element (IE), a served cells new radio (NR) to add IE, a slice identifier of a first network slice supported by a cell of the second base station, and a second served cell information NR IE indicating that the cell of the second base station is in a second closed access group (CAG). The first base station sends, to the second base station, an NG-RAN configuration update acknowledge message including a first served cell information NR IE indicating that a cell of the first base station is in a first CAG. The first base station sends, to the second base station, a handover request message to the cell of the second base station.

    摘要： A central unit (CU) of a base station sends, to a distributed unit (DU) of the base station, a first message indicating that a wireless device supports a traceability to Coordinated Universal Time (UTC). The CU receives, from the DU, a second message indicating whether the DU provides the traceability to UTC. The CU sends, to the wireless device, an indication whether the base station provides traceability to UTC.
