Basic Work of MSC (Mobile Switching Centre)
- Exchange where calls are established, maintained and released
- Database for all subscribers and their associated features.
- Communicates with the BSCs on the A interface and with PSTN on fixed line.
- MSC is weighted on the number of subscribers it can support. For example, an MSC of 1 lakh subscribers means one MSC is enough till subscriber base increases up to 1 lakh, beyond which another MSC is required.
