Specifically, the distributed unit sends a control plane message (referred to as a third message) to the centralized unit, where the third message includes the RRC connection request. Optionally, the RRC connection request may be carried into a container, and then the container is carried in the third message for sending.
Further, the third message may further include at least one of the following information:
a first terminal identifier corresponding to the terminal, an identifier of a cell accessed by the terminal, and a second terminal identifier corresponding to the terminal.
The first terminal identifier is used to identify the terminal on the air interface, and the second terminal identifier is an identifier allocated by the distributed unit for the terminal on a control plane interface between the distributed unit and the centralized unit.
Optionally, all of the foregoing three pieces of information may be sent in the third message, or some of the foregoing three pieces of information may be sent in the third message, and the others are sent through another control plane message, or all of the foregoing three pieces of information may be sent through another control plane message.
