Main Control Functions
The main processor of SOL230 takes the highest role of the system, and performs
the communication path setup between the UE and the EPC, system operation and
maintenance, and so on.
It also manages the status for all hardware and software in SOL230, allocates and
manages resources, collects alarms, and reports all status information to the EMS.
