Wireless connection control method, distributed unit, centralized unit, and base station system
摘要
說明書
sending, by the centralized unit, a second message to the distributed unit, where the second message is used to instruct to establish the air interface control plane connection between the terminal and the distributed unit.
In a possible design, the first message is included in a third message for transmission, and the third message is transmitted through a control plane connection between the distributed unit and the centralized unit; and the third message further includes 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, where 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.
In a possible design, the second message is transmitted through the control plane connection; correspondingly, the second message includes a third terminal identifier; and the third terminal identifier is an identifier allocated by the centralized unit for the terminal on the control plane interface between the distributed unit and the centralized unit.
In a possible design, the method further includes:
sending, by the centralized unit, first signaling bearer configuration information to the distributed unit.
In a possible design, the first signaling bearer configuration information includes at least one of the following information:
