Question: In a dual USIM device (MUSIM) in RRC_IDLE/RRC_INACTIVE state, connected to both Network A and Network B, what is the primary goal of the mechanism invoked when the device detects overlapping paging occasions on both networks?
Option 1: To prioritize one network's paging over the other based on predefined UE implementation rules.
Option 2: To simultaneously process paging from both networks without conflict resolution.
Option 3: To switch to RRC_CONNECTED state on both networks to avoid collisions.
Option 4: To ignore paging from one network until the other's paging cycle is complete.
Explanation: The primary goal of paging collision avoidance in a dual USIM device scenario is to prevent conflicts when both associated networks (Network A and Network B) have overlapping paging occasions. Since it's left to UE implementation to decide how to select one of the two RATs/networks for this purpose, the most logical approach among the given options is to prioritize one network's paging over the other based on rules defined within the UE's implementation. This ensures that at least one network's paging is successfully processed without conflict, aligning with the purpose of avoiding paging collisions as described.
