Question: In a Super-Charged network, during PS-domain Location Updating for a subscriber with retained subscription data, what action does the HLR take if the previous network entity supports Super-Charger functionality?
Option 1: The HLR always sends updated subscription data to the serving network entity.
Option 2: The HLR does not cancel the location information at the previous network entity unless specifically instructed otherwise.
Option 3: The HLR initiates a new attach procedure for the subscriber.
Option 4: The HLR automatically detaches the subscriber from the current serving network entity.
Explanation: According to the Super-Charger technical realization, if the previous network entity supports the Super-Charger functionality, the HLR shall not cancel the location information at the previous network entity unless there's an explicit instruction. This ensures seamless continuity of service for subscribers moving within the network while leveraging retained data efficiently.
