Abstract

The invention provides a control method of a wireless access network, network equipment and a system. The method comprises the following steps: sending a management request to a remote radio unit (RRU) / active antenna unit (AAU); and receiving a management request response corresponding to the management request from the RRU / AAU side, wherein the management request response carries first state information and / or second state information, the first state information is used for indicating the state of the RRU / AAU, and the second state information is used for indicating the state of a color lightmodule on the RRU / AAU. The active WDM equipment provided by the embodiment of the invention can manage the color light module and the link in the RRU / AAU. Through the joint management of the RRU / AAUby the wireless and transmission system, the management problem of the optical fiber network in the forward transmission network of the mobile communication system and the color light module in the RRU / AAU is solved with low cost, and the operation and maintenance capability of the network is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a control method, network equipment and system of a wireless access network. Background technique [0002] With the development of mobile communication technology, radio access network (Radio Access Network, RAN) functions are segmented, the fifth generation (5 th Generation, 5G) mobile communication system, RAN is reconfigured as Remote Radio Unit (RRU) or Active Antenna Unit (Active Antenna Unit, AAU), Distributed Unit (Distributed Unit, DU), Centralized Unit (Centralized Unit, CU) multi-level architecture, the network deployment of the transport network can be divided into fronthaul, midhaul, and backhaul. Among them, the proportion of centralized base stations in the centralized radio access network (Centralized-Radio Access Network, C-RAN) is increasing day by day. A single computer room may cover 6-10 RRU / AAU locally and remotely, and even 11- 30 RRU / AAU. ...
