Patent ID: 8914486

Claim:
A method for implementing identity identifier and location separation, comprising: an ID-loc-split Control Functions entity sending a mapping response to an ID-loc-split Mapping Functions entity after receiving a location change request, wherein the mapping response contains a location where a terminal host is currently located and an identity identifier; the ID-loc-split Mapping Functions entity updating a mapping relationship between the terminal host identity identifier and the terminal host location according to the mapping response; and the ID-loc-split Control Functions entity selecting an address corresponding to the location where the terminal host is currently located from the updated mapping relationship between the terminal host identity identifier and the terminal host location, wherein after selecting the address, the method further comprises: the ID-loc-split Control Functions entity returning the selected address to a network access control component; the network access control component sending a response message of the location change request to a resource control component, wherein the response message contains the selected address; the resource control component receiving the response message, releasing the resource allocated for the location change, and sending a switch status notice to a transport functions component, wherein the switch status notice contains the selected address; and the transport functions component sending switch information notice to a terminal, and the terminal transmitting information using the address, wherein each of the ID-loc-split Control Functions entity, the ID-loc-split Mapping Functions entity, the network access control component, the resource control component, and the transport functions component comprising a computer processor and respective memory, the respective memory storing computer-readable instructions which when executed by the computer processor implement the functions of the said components.
