The terminal device sequentially sends the protocol data unit set 2, the protocol data unit set 5 and the protocol data unit in the protocol data unit set 7 to the network device according to the sequence number sequence from small to large. Correspondingly, the network device receives according to the timer and reorders the received PDU sets.
