Question: What happens to Circuit Switched (CS) domain services like SMS during General Packet Radio Service (GPRS) mobility management procedures?
Option 1: They continue uninterrupted.
Option 2: They are prioritized over GPRS services.
Option 3: They are suspended.
Option 4: They are terminated.
Explanation: During GPRS mobility management procedures, Circuit Switched (CS) domain services like SMS are suspended to ensure seamless execution of the mobility management functions. This is necessary because these procedures require exclusive control over the radio interface and cannot be executed concurrently with CS domain services.
