GSM Inter MSC Handover Call Flow
Handing over a GSM call is a complicated procedure. It is even more so when the source and target GSM cells are controlled by different MSCs. The following call flows analyze the different steps involved in a inter-MSC handover:
- The source BSC analyzes the signal quality measurement reports and initiates a handover.
- The source MSC finds that the call needs to be handed over to a cell controlled by a different MSC.
- The source MSC and target MSC interact and then command the UT to move to the new cell.
- The target MSC informs the source MSC when the call has been successfully handed over.
- The source MSC releases the radio resources for the call. Note that the call is still routed via the source MSC.
