Embodiment 1
[0056] Such as image 3 As shown, in this embodiment, the initiator (or responder) in the communication process moves to a new location LOC 1 , does not have an ID / LOC in its mapped server mapping table 1 Mapping information. In the figure, ILMS-FE1 / ILMU-FE1 is the ID / LOC mapping server of UE1, and ILMS-FE2 / ILMU-FE2 is the ID / LOC mapping server of UE2.
[0057] ID / LOC mapping registration / update steps:
[0058] During communication, when UE1 moves, that is, a handover occurs, and UE1 obtains a new IP address (the step for UE1 to obtain a new IP address can be realized by using existing technologies), that is, obtains a new LOC 1 , but there is no ID / LOC in the mapping table of UE1's mapping server 1 Mapping information, ID / LOC to be registered by UE1 in its mapping server 1 mapping:
[0059] Step 101, UE1 sends an identity and location mapping update query (mapping update query) to its mapping server ILMS-FE1 / ILMU-FE1, requesting to update the LOC mapped with the identit...
Embodiment 2
[0069] Such as Figure 4 As shown, in this embodiment, the initiator (or responder) in the communication process moves to a new location LOC 1 , with ID / LOC stored in its mapping server mapping table 1 Mapping information, that is, the initiator has previously used the LOC 1 .
[0070] ID / LOC mapping registration / update steps:
[0071] During communication, when the position of UE1 moves, that is, a handover occurs, and UE1 obtains a new IP address, that is, obtains a new LOC 1 , and there is ID / LOC in the mapping table of UE1's mapping server 1 Mapping information, UE1 needs to update its registration ID / LOC in the mapping server 1 mapping:
[0072] Step 401, UE1 sends the ID and location mapping update query to its mapping server ILMS-FE1 / ILMU-FE1, requesting to update the LOC mapped with the ID Node ID to the current location LOC 1 ;
[0073] Step 402, after ILMS-FE1 / ILMU-FE1 receives the identity and location mapping updatequery, it uses the Node ID of UE1 to perfo...
