摘要

This application provides a wireless connection control method relating to a base station system including a centralized unit and a distributed unit, wherein the centralized unit communicates with the distributed unit, and the distributed unit communicates with a terminal through an air interface. The method includes: first receiving, by the distributed unit, a first message sent by the terminal, where the first message is used to request to establish an air interface control plane connection for the terminal; then sending, by the distributed unit, the first message to the centralized unit; and then receiving, by the distributed unit, a second message sent by the centralized unit, where the second message is used to instruct to establish the air interface control plane connection between the terminal and the distributed unit. The method may implement wireless connection control in a 5G system when functions of a base station are separated.

說明書

A tenth aspect of this application provides a distributed unit, where the distributed unit has functions of implementing the distributed unit in the second aspect. These functions may be implemented by hardware, or may be implemented by hardware by executing corresponding software. The hardware or the software includes one or more modules corresponding to the foregoing functions.

In a possible design, the distributed unit may include a receiving module, a processing module, and a sending module. These modules may perform the corresponding functions in the foregoing method. For example, the receiving module is configured to receive a first message sent by a terminal; the processing module is configured to send an eighth message to the terminal based on the first message, where the eighth message is used to instruct to establish an air interface control plane connection for the terminal; and the sending module is configured to send a ninth message to a centralized unit, where the ninth message includes a connection parameter used to establish the air interface control plane connection.

An eleventh aspect of this application provides a distributed unit, where the distributed unit has functions of implementing the distributed unit in the third aspect. These functions may be implemented by hardware, or may be implemented by hardware by executing corresponding software. The hardware or the software includes one or more modules corresponding to the foregoing functions.
