Method, system and device for implementing identity identifier and location separation

A system for implementing identity identifier and location separation, comprising:

• a resource control component, arrange to send a location change request;
• a network access control component, arrange to receive the location change request, and send a mapping request to an ID-loc-split Mapping Functions entity;
• the ID-loc-split Mapping Functions entity, arrange to receive the mapping request, send a location update request to an ID-loc-split Control Functions entity, and update a mapping relationship between a terminal host identity identifier and a terminal host location according to a mapping response returned from the ID-loc-split Control Functions entity, wherein the mapping response contains the location where a terminal host is currently located and the identity identifier;
• and
• the ID-loc-split Control Functions entity, arrange to receive the location update request, return the mapping response message, and select 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 the system further comprises:
• a transport functions component, arrange to determine to implement a location change, and interact with the resource control component to apply for resource which is needed in the location change;
• wherein the ID-loc-split control functions entity is further arrange to return the selected address to the network access control component via the ID-loc-split mapping functions entity;
• the network access control component is further arrange to send a response message of the location change request to the resource control component, wherein the response message contains the selected address;
• the resource control component is further arrange to receive the response message, and send a switch status notice to the transport functions component, wherein the change status notice contains the selected address;
• and
• the transport functions component is further arrange to send a switch information notice to the terminal, wherein the switch information notice contains the selected location identifier, so as to make the terminal transmit information using the address identifier,
• 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.

A device for implementing identity identifier and location separation, comprising:

• an ID-loc-split Mapping Functions entity, arrange to store a mapping relationship between a terminal host identity identifier and a terminal host location, send a location update request to an ID-loc-split Control Functions entity after receiving a mapping request sent from a network access control component, and update the mapping relationship between the terminal host identity identifier and the terminal host location according to a mapping response sent from the ID-loc-split Control Functions entity, wherein the mapping response contains the location where the terminal host is currently located and the identity identifier;
• and
• the ID-loc-split Control Functions entity, arrange to receive the location update request, return the mapping response message, select 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, and return the selected address to the network access control component via the ID-loc-split Mapping Functions entity,
• wherein after receiving the selected address, the network access control component sending a response 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.
