Abstract
In a system for controlling a radio base station, an out-of-band emergency channel based on a power cable is established between a baseband unit (BBU) and a remote radio unit (RRU) such that even when a unique communications interface common public radio interface (CPRI) between the BBU and the RRU is abnormal, the BBU can still effectively control the RRU using the out-of-band emergency channel. In another system for controlling a radio base station, out-of-band emergency channels based on power cables are established among multiple RRUs such that even when a unique communications interface CPRI between a BBU and a target RRU is abnormal, the BBU can still effectively control the target RRU using an out-of-band emergency channel between any RRU (a unique communications interface CPRI of the RRU is normal) and the target RRU, and the BBU can effectively control the RRU.
