Step S122, resolves the cell configuration mark in described Cell Configuration message, judges whether described cell configuration mark is that mark is set up in community.
In such as table one, if cell configuration is designated 0, so can judge that Cell Configuration message is the message of newly-built community.
Step 130, if the Cell Configuration message received is the message of newly-built community, then calculates the cell power sum of community yet to be built and built community, obtains gross power;
If the message of newly-built community, namely described indoor baseband processing unit requires the community of performance described in this Cell Configuration message newly-built, before so RRU Ce Zegai community is set up, calculate the cell power of this community yet to be built, with the summation of the cell power of other built communities under RRU.
