Question: In a 3GPP network, what determines which inter-system mobility policy to apply when multiple policies have overlapping validity areas for a User Equipment (UE)?
Option 1: The type of access technology prioritized by the UE
Option 2: The time of day the UE is accessing the network
Option 3: The specific location within the overlapping area based on cell ID
Option 4: The Rule Priority assigned to each inter-system mobility policy
Explanation: According to telecom standards, when multiple policies overlap, the network uses the 'Rule Priority' as a discriminator to determine which policy to apply, ensuring enforcement in line with operator preferences and providing a clear hierarchy for policy application.
