  • COMMUNICATIONS METHOD AND APPARATUS
    Publication number: 20210218817
    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.
