AI Technical Summary
In a communication network, when a UE is reassigned from an initial core network element to a target core network element, existing technologies cannot guarantee the integrity protection of message exchange, making secure communication links unsuitable and potentially violating the isolation requirements of the core network.
Through the collaboration of access network elements and initial core network elements, a secure relocation process for the UE is executed from the initial core network element to the target core network element. This includes receiving and sending messages to ensure integrity protection and isolation during the secure relocation process and to prevent UE upgrades.
It achieves integrity protection without UE upgrade during UE reassignment, meets the isolation requirements of the core network, and ensures the continuity and integrity of secure communication links.
