Communication method of BBU (Building Base band Unit) and RRU (Radio Remote Unit) and base station

Bbu与rru的通信方法及基站

Abstract

The invention provides a communication method of a BBU (Building Base band Unit) and an RRU (Radio Remote Unit) and a base station. The communication method comprises the following steps of upgrading an old protocol installed on multiple RRUs, which are connected in series step by step and are connected with an auxiliary BBU based on the old protocol by the auxiliary BBU which is provided with the old protocol; disconnecting a first state RRU and the auxiliary BBU after the old protocol of the first state RRU is upgraded into a new protocol, and connecting the first state RRU to a main BBU which is provided with the new protocol; carrying out communication between the first stage RRU and the main BBU basing on the new protocol; and carrying out the communication between the main BBU and RRUs at different stages through the first RRU. According to the communication method and the base station, provided by the invention, through the upgrade, the interface compatibility problem between the main BBU and the RRUs is effectively solved, and the selectable range of the RRU is enlarged.
本发明提供一种BBU与RRU的通信方法及基站,其中方法包括:安装有旧协议的辅助BBU基于所述旧协议对与该辅助BBU相连的多个逐级串联的RRU上安装的旧协议进行升级;当第一级RRU的所述旧协议成功升级为新协议后,将所述第一级RRU与所述辅助BBU断开,并转接到安装有所述新协议的主用BBU上;所述第一级RRU基于所述新协议与所述主用BBU进行通信;所述主用BBU经由所述第一级RRU与各级所述RRU进行通信。本发明通过升级,有效解决了主用BBU与RRU之间的接口兼容问题,扩大了RRU的可选范围。
