Problems solved by technology

[0008] The existing RRU cascading technology requires that the optical port rates of all levels of RRUs on the same link be consistent, which on the one hand causes a huge waste of module optical port resources; When connecting, the low optical port rate RRU ultimately limits the improvement of the entire link rate

Abstract

The invention provides an optical port resource configuration method and apparatus of cascading devices in a base station, the base station, and a communication system. The method includes: determining optical port resource configuration information of each stage of cascading device through the optical port rate based on each stage of the cascading device and data volume information born by each stage of the cascading device; and configuring the optical port resource configuration information to each stage of the cascading device so that optical port resources are configured by corresponding cascading devices according to the optical port resource configuration information. According to the method and apparatus, reasonable and effective configuration of the optical port resources in cascaded RRU links can be realized, the waste of the optical port resources is avoided, and the cost of base station equipment is effectively reduced.

Description

technical field [0001] The present invention relates to BBU (Baseband Unit, indoor baseband processing unit) and RRU (RadioRemote Unit, radio frequency remote unit) interface technology in the field of communication technology, in particular to a method and device for configuring optical port resources of cascaded devices in a base station, a base station, and a communication device. system. Background technique [0002] In a wireless communication system, a wireless access network is composed of NodeBs (base stations). NodeB is composed of BBU (Baseband Unit, indoor baseband processing unit) and RRU (Radio Remote Unit, remote radio unit). figure 1 shown. The BBU and RRU are generally connected through optical fibers or cables to realize signaling and data interaction between the BBU and RRU. [0003] The most common networking modes between the BBU and RRU are star networking and cascade networking. [0004] The star networking method is shown in 2. There are n RRU modu...
