Question: In an MSC (Mobile Switching Center) server, when a procedure with the Media Gateway (MGW) fails during a BSS internal handover, what action is taken regarding MGW resources that have already been allocated?
Option 1: The MGW resources are immediately reassigned to another call.
Option 2: The MSC server attempts to restart the failed procedure before taking any action on the MGW resources.
Option 3: The MGW resources are released using the Release Termination procedure.
Option 4: The MGW resources are put into a standby mode awaiting further instructions.
Explanation: When an MSC server encounters a failure during a procedure with the MGW, especially in the context of a BSS internal handover, it must efficiently manage allocated resources to maintain network stability. Releasing seized MGW resources via the Release Termination procedure ensures that these resources are made available for other calls or procedures, preventing resource bottlenecks and potential further failures. This approach aligns with efficient failure handling practices in telecommunications networks, prioritizing resource optimization and minimizing service disruptions.
