Question: What mechanism is utilized in MAP (Mobile Application Part) to negotiate the protocol version between two entities for a MAP-user signalling procedure?
Option 1: Application-Context-Name based version negotiation
Option 2: SCCP (Signalling Connection Control Part) protocol version auto-detection
Option 3: Static protocol version configuration in Gateway Location Register (GLR)
Option 4: Dynamic protocol version synchronization via ITU-T Recommendations
Explanation: In the context of Mobile Application Part (MAP), negotiating the correct protocol version between entities is crucial for successful signalling procedures. The use of an application-context-name provides a flexible and standardized method to achieve this, ensuring compatibility across different versions of the protocol. This approach allows for efficient adaptation to evolving network requirements without disrupting existing infrastructure.
