Operation Maintenance Center (OMC) is used to monitor and maintain the performance of each Mobile Station (MS), Base Station (BS), Base Station Controller (BSC) and Mobile Switching Center (MSC) within a GSM system. The OMC has three main functions which are:
- To maintain all telecommunications hardware and network operations with a particular market.
- Manage all charging and billing procedures.
- Manage all mobile equipment in the system.
The OMC is dedicated to each of these tasks and has provisions for adjusting all base station parameters and billing procedures, as well as for providing system operators with the ability to determine the performance and integrity of each piece of subscriber equipment in the system.
