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...

Abstract

A method, a system and a device for realizing mobile handoff in an IPSPLIT network are disclosed in the present invention, and realize the seamless handoff of UE (User Equipment) and guarantee the continuity of service. The method for realizing mobile handoff in the IPSPLIT network comprises the steps that in the process of communication, when the position of a terminal (UE) changes, the UE requests an Id-loc-mapping control functions (ILMCF) entity to update the mapping relation of a UE identifier (Node ID) and a location (LOC); and the UE updates the connection of the UE with a communication opposite terminal and establishes a channel and communicates.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, system and device for realizing mobile handover in an Identity and Location Separation (IPSPLIT) network. Background technique [0002] In the current Internet layer structure, except for the physical layer, each layer protocol entity has its own name space, which are the MAC address of the link layer, the IP address of the network layer, the IP address and port number of the transport layer, and the application layer. domain name. In these namespaces, the MAC address is only required to be unique within the subnet, and the port number is only required to be unique within the host. Therefore, there are two important global namespaces in the Internet—IP address and domain name. The domain name and IP address are resolved through DNS (DomainName Server, domain name server). In such a name space structure, the IP address has dual functions, it is not only ...
