  • Publication number: 20220225465
    Abstract: Embodiments of this application provide a configuration method and apparatus. When indicating, by using an RRC connection release message, a terminal to enter an inactive state from a connected state, a network device may include, in the RRC connection release message, a configuration parameter allocated to the terminal in the inactive state. That is, the terminal receives the radio resource control RRC connection release message sent by the network device, where the RRC connection release message includes first information used to indicate a target configuration parameter. In this way, the terminal may enter the inactive state based on the RRC connection release message, and determine a context parameter of the inactive state based on the first information, so that the configuration parameter is properly allocated to the terminal in the inactive state.

  • Publication number: 20220225254
    Abstract: This application provides a method for processing timing advance TA of a terminal, and an apparatus. A terminal obtains a correspondence between first TA and a beam, determines, based on the correspondence, the beam corresponding to the first TA, and further determines, based on the beam corresponding to the first TA, whether the first TA is invalid. In other words, in embodiments of this application, the terminal may determine, by using a finer granularity, whether the first TA is invalid, and this helps trigger selection of more appropriate TA. Therefore, compared with a conventional solution, embodiments of this application can further reduce interference between uplink transmission.

  • Patent number: 11375025
    Abstract: A communications method and apparatus are provided. The method includes: A first access network device sends a first message to a core network device, where the first message is used to indicate to suspend one or both of a first PDU session and a second PDU session. The first PDU session and the second PDU session are PDU sessions that are established as requested by a same terminal, and are used to transmit a duplicated data packet. According to the method, when a condition for implementing reliable transmission is not met, the core network device can be indicated to suspend the PDU session. In this way, a PDU session does not need to be re-established, and signaling overheads for establishing the PDU session are saved.
