Abstract: This application provides a communication method and a communications device. The method includes: A first device receives a first message sent by a second device. The first message is used to indicate a bearer configuration of a bearer of the first device and an initial status of the bearer configuration, and the bearer configuration includes a first bearer configuration and/or a second bearer configuration. The first device determines the bearer configuration and the initial status of the bearer configuration based on the first message. According to the technical solutions in embodiments of this application, a bearer configuration of a terminal device and an initial status of the bearer configuration of the terminal can be indicated. Because both the bearer configuration of a bearer of the terminal and the initial status of the bearer configuration of the terminal are indicated, communication efficiency is improved.

Abstract: This application provides a data processing method and apparatus, and a computer storage medium. When a PDCP entity over a UM DRB is re-established, or when a cell handover occurs and the PDCP entity over a UM DRB uses a key used before the handover, the PDCP entity determines a first SDU, where the first SDU is an SDU that is associated with a sequence number by the PDCP entity but whose corresponding data has not been transmitted through an air interface; and delivers a PDU corresponding to the first SDU to an RLC entity. Data corresponding to the first SDU is redelivered, to avoid a data packet loss caused by preprocessing of the PDCP entity.

Abstract: A route update method relating to a communications field includes: sending a medium access control protocol data unit (MAC PDU), wherein the MAC PDU comprises a first buffer status report (BSR); and canceling, in response to the sending of the MAC PDU, a scheduling request triggered prior to the MAC PDU assembly. The first BSR comprises a buffer status up to the last event that triggers a BSR prior to the MAC PDU assembly.

Abstract: The method is applied to a communications system including a first network device, a second network device, and a terminal device. The terminal device is communicatively connected to the first network device and the second network device respectively. The method includes: sending, by a network device, a first message to the terminal device, where the first message is used to determine that the terminal device stops communication with the first network device, or the first message is used to determine that the terminal device releases a protocol stack and a data radio bearer that are corresponding to the first network device; and the network device is the first network device or the second network device. Therefore, power consumption of the terminal device or the first network device and waste of air interface resources can be reduced, and flexibility can effectively be improved in a communication process.
