Main Controller Function
The main processor of the Indoor Pico Cell takes the highest role, and performs the
communication path setup between UE and EPC, system operation and maintenance, etc.
It also manages the status for all hardware/software in the Indoor Pico Cell, allocates and
manages resources, collects alarms, and reports all status information to the LSM.
