Abstract

A method, system, mapping forwarding server and access router for mobile communication control are provided in the present invention. The method includes a flow of sending a data message from a source mobile terminal to a destination mobile terminal, including the following steps: A, a source access router receiving a first data message sent by the source mobile terminal, and executing step B; B, encapsulating a location identifier according to an identity identifier in the first data message, and acquiring a second data message; forwarding the second data message to a destination access router connected to the destination mobile terminal according to the location identifier in the second data message; and C, the destination access router stripping out the location identifier encapsulation in the second data message to return the second data message to the first data message, and forwarding the first data message to the destination mobile terminal.

First claim

What is claimed is:

1. A system for mobile communication control, comprising an access router, which comprises a mapping manager, a message forwarding processor, and a message encapsulation processor connected with the mapping manager and the message forwarding processor, wherein:
when the access router acts as a source access router connected with a source mobile terminal through a wireless link, in the source access router, the mapping manager is configured to manage a mapping relationship between an identity identification and a location identification of the mobile terminal; the message encapsulation processor is configured to encapsulate the location identification according to the identity identification in a first data message sent out by the source mobile terminal to obtain a second data message; the message forwarding processor is configured to transmit the second data message to a destination access router connected to a destination mobile terminal according to the location identification encapsulated in the second data message;
when the access router acts as the destination access router connected with the destination mobile terminal through a wireless link, in the destination access router, the mapping manager is configured to manage the mapping relationship between the identity identification and the location identification of the mobile terminal; the message encapsulation processor is configured to strip the location identification in the second data message and de-encapsulate the second data message into the first data message; the message forwarding processor is configured to transmit the first data message to the destination mobile terminal according to the identity identification in the first data message which is obtained by de-encapsulating the second data message;
wherein, the system for mobile communication control divides a network into an access network and a backbone network, the access router is connected with the access network and the backbone network, the identity identification is only used in the access network, the location identification is only used in the backbone network, and the identity identification is unique for each user in the access network and keeps unchanged during movement; and
wherein the backbone network forms two logically independent functional planes: a mapping forwarding plane and a general forwarding plane, the mapping forwarding plane is configured to store identity identification-location identification mapping information of all mobile terminals in the whole network.

2. The system according to claim 1 , wherein, the system further comprises a mapping forwarding server, which comprises the mapping manager configured to manage the location identification and the identity identification of the mobile terminal, where the location identification and the identity identification of the mobile terminal are related with each other; and the system further comprises an instructor configured to perform instruction cooperation with the access router, and query, maintain, update and delete the mapping relationship between the location identification and the identity identification of the mobile terminal.

3. The system according to claim 2 , wherein,
the source access router further comprises a querier connected with the mapping manager and a message buffer connected with the message encapsulation processor; when the mapping manager of the source access router does not store the mapping relationship between the identity identification and the location identification of the destination mobile terminal:
the message buffer is configured to cache the first data message which is transmitted by the source mobile terminal firstly and whose destination address is the identity identification of the destination mobile terminal;
the querier is configured to query the mapping relationship between the identity identification and the location identification of the destination mobile terminal from the forwarding mapping server;
the mapping manager is configured to newly add the mapping relationship between the identity identification and the location identification of the destination mobile terminal according to a query result;
the message encapsulation processor is further configured to perform encapsulation processing on the first data message in the message buffer according to the newly added mapping relationship.

4. The system according to claim 2 , wherein,
the mapping forwarding server further comprises a message encapsulating and forwarding unit connected with the mapping manager, and the source access router further comprises the querier connected with the mapping manager, and when the mapping manager in the source access router does not store the mapping relationship between the identity identification and the location identification of the destination mobile terminal:
the message forwarding processor of the source access router is further configured to forward the first data message which is transmitted by the source mobile terminal firstly and whose destination address is the identity identification of the destination mobile terminal to the mapping forwarding server;
the message encapsulating and forwarding unit of the mapping forwarding server is configured to encapsulate the location identification according to the identity identification in the first data message to obtain the second data message, and route the second data message to the destination access router connected with the destination mobile terminal;
the querier of the source access router is configured to query the mapping relationship between the identity identification and the location identification of the destination mobile terminal from the mapping forwarding server; the mapping manager of the source access router is configured to newly add the mapping relationship between the identity identification and the location identification of the destination mobile terminal according to the query result.

5. The system according to claim 2 , wherein, the access router further comprises a status notifier connected with the mapping manager, and the status notifier is configured to allocate the location identification to the mobile terminal when the mobile terminal moves to a predetermined area or the status of the mobile terminal changes; inform the mapping forwarding server of the allocated location identification of the mobile terminal; the instructor of the mapping forwarding server is configured to update the mapping relationship between the identity identification and the location identification of the mobile terminal according to the informed location identification.

6. The system according to claim 2 , wherein, the access router further comprises an access manager connected with the status notifier and a mobility manager connected with the access manager and the message forwarding processor, and the access manager is configured to manage access information of the mobile terminal connected to the access router, and provide an access service of the mobile terminal; the mobility manager is configured to process a switching flow of the mobile terminal when the location of the mobile terminal changes, maintain a connecting relationship between the mobile terminal and the correspondent node, and initiates a routing optimization flow to the access router connected with the correspondent node when the mobile terminal switches to access.

7. The system according to claim 1 , wherein, the access router further comprises an access manager connected with the status notifier and a mobility manager connected with the access manager and the message forwarding processor, and the access manager is configured to manage access information of the mobile terminal connected to the access router, and pro
