Abstract: This application discloses a communications method. The method may include: receiving, by a receiving party, indication information sent by a first device, where the indication information is used to indicate at least one intermediate sequence number; receiving a data packet of the bearer sent by the first device; and skipping the at least one intermediate sequence number based on the indication information, deciphering, by using the old key, a data packet that is located on the bearer and whose sequence number is followed by the at least one intermediate sequence number, and deciphering, by using the new key, a data packet that is located on the bearer and whose sequence number follows the at least one intermediate sequence number.
