Question: Upon receiving a Handover Complete message, what action does the MSC-A server take towards the MSC-B server regarding the call?
Option 1: Initiates Call Setup to re-establish the connection
Option 2: Initiates Call Clearing as per specified call clearing procedures
Option 3: Sends a Handover Request to attempt another handover
Option 4: Waits for further instructions from MSC-B server before proceeding
Explanation: Upon successful handover, the source MSC (MSC-A) would typically release its resources related to the call, which is achieved by initiating call clearing towards the target MSC (MSC-B). This ensures a clean release of resources at the source end after the handover is completed, aligning with efficient network resource management principles in telecom networks.
