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.

Abstract: A data transmission method, a device, and a communications system are described. The method includes generating, by a terminal device, first indication information. The first indication information is used to indicate logical channel groups having to-be-sent data and amount of to-be-sent data on part of the logical channel groups having to-be-sent data. The method includes sending, by the terminal device, the first indication information. According to the data transmission method, the device, and the communications system provided in the described embodiments, when a current quantity idle bits in a MAC PDU is insufficient, the terminal device may indicate, to a network device by using the first indication information, the LCGs having to-be-sent data on the terminal device. In this way, uplink transmission resource allocation improved efficiency.

Abstract: A counting method and a communications apparatus are provided. The method includes: determining to retransmit a first protocol layer data packet; and if the retransmission is retransmission for the first time, initializing a retransmission counter associated with the first protocol layer data packet; or if the retransmission is not retransmission for the first time and the first protocol layer data packet is not pending for retransmission, updating the retransmission counter or keeping a value of the retransmission counter unchanged. In this way, RLF can be correctly triggered, to reduce a quantity of times of unnecessary RLF triggering and reduce overheads.

Abstract: A data integrity protection method and apparatus in a network environment are described. A terminal device obtains an integrity protection algorithm and a key corresponding to a session or a flow, and a DRB corresponding to the session. The terminal device performs, by using the integrity protection algorithm and the key corresponding to the session, integrity protection on data of the DRB corresponding to the session or the flow, where one session includes a plurality of flows. Different integrity protection algorithms and keys can be used for different sessions, and different integrity protection algorithms and keys can also be used for different flows. In this way, integrity protection is more flexible and meets security requirements of a same user for different services.
