Study Notes

GSM System Subsystems

The three major subsystems in a GSM system are:
- Base Station Subsystem (BSS)
- Network and Switching Subsystem (NSS)
- Operation and Support Subsystem (OSS)

Dominant Interfaces in GSM

The dominant interfaces in the GSM system are:
- Abis interface (between BSS and NSS)
- A interface (between NSS and NSS)

PLMN Service Area

The PLMN (Public Land Mobile Network) service area in the GSM system is the area covered by a single network operator.

Mobile Network Structure

The structure in a mobile network is significant because it allows for efficient communication between different components and enables the provision of various services to subscribers.

Call Routing

All incoming calls for a GSM/PLMN network are routed to the Mobile Switching Center (MSC).
