If ring exists such RRU, no matter carrier number above it divides on which light mouth at looped network two ends, all there is problem (the IQ capacity needed for the carrier number of this RRU that carrier wave all can not distribute to single light mouth, IQ capacity sum needed for the carrier number adding RRU before this side, exceed the maximum IQ capacity that this sidelight module can carry, needed for the carrier number of i.e. home cell, RRU1 and RRU2 place, IQ capacity sum has exceeded the IQ capacity of main light port), another sidelight mouth optical module also has vacant capacity simultaneously, so, this RRU can be allowed to be operated in load sharing mode, namely two light mouths of this RRU all work in first line of a couplet light mouth pattern, user face data is carried on two light mouths, make the IQ capacity of the light mouth optical module of RRU both sides all divide as far as possible, there is no IQ waste of capacity, the ownership light mouth of this RRU, can select at main light port or standby light mouth.Generally, this RRU is the RRU of afterbody.
Step 502, RRU be link setup on its ownership light mouth;
In this step, according to the result of step 501 decision-making, the mode of operation of each RRU on ring is set respectively; When the mode of operation of RRU is cascade mode, described RRU is by self working in ownership light mouth and the BBU link setup of this RRU on the light mouth of first line of a couplet light mouth pattern and described BBU.
After step 503, RRU are working properly, home cell can be used, and NodeB reports RNC by audit;
Step 504, RNC initiate community and set up request;
Step 505, NodeB receive community and set up request, if the RRU belonging to this community works in cascade mode, then carrier wave is all based upon on its ownership light mouth; If the RRU belonging to this community works in load sharing pattern, then its portion of carriers is distributed in main light port, and remaining allocation of carriers is on standby light mouth.
