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.
