Option 1: To provide identity confidentiality and protect users against being identified and located by an intruder.
Option 2: To optimize routing area updates and reduce signaling overhead.
Option 3: To enable seamless handovers between different radio access technologies.
Option 4: To support law enforcement agencies in tracking user locations.
Explanation: The P-TMSI reallocation procedure is designed to provide identity confidentiality, which means protecting users against being identified and located by an intruder. This is a critical security feature in GPRS networks, as it helps prevent unauthorized parties from tracking user movements and activities.
