1. A method for getting user equipment information through short messages, comprising:

receiving, by a short message service center, a request message for inquiring current state information of a user equipment from a third party service equipment;

sending, by the short message service center, a get routing message to a Home Location Register (HLR) to get the current state information of the user equipment;

receiving, by the short message service center, a get routing message response from the HLR, the get routing message response containing the current state information of the user equipment;

sending, by the short message service center, a delivery message to the user equipment via a Mobile Switching Center (MSC);

receiving, by the short message service center, a delivery message response containing the current state information of the user equipment from the user equipment via the MSC;

comparing, by the short message service center, the current state information contained in the get routing message response received from the HLR with the current state information contained in the delivery message response received from the user equipment to obtain the latest state information of the user equipment; and

responding, by the short message service center, to the third party service equipment with the latest state information of the user equipment.

2. The method for getting user equipment information through short messages according to claim 1 , wherein the request message for inquiring current state information of a user equipment is an interacting message, and the request message carries a field of get terminal routing.

3. The method for getting user equipment information through short messages according to claim 2 , wherein if the user equipment is in an abnormal state, the state information in the delivery message response of the user equipment is error code information; if the user equipment is in a normal state, the state information in the delivery message response of the user equipment is the latest state information.

4. The method for getting user equipment information through short messages according to claim 2 , wherein the getting routing message contains a field of priority level.

5. The method for getting user equipment information through short messages according to claim 1 , wherein the responding, by the short message service center, to the third party service equipment with the current state information of the user equipment in the delivery message response comprises:

the short message service center notifying the third party service equipment of the current state information of the user equipment by returning a request message response carrying the current state information of the user equipment to the third party service equipment.

6. The method for getting user equipment information through short messages according to claim 1 , wherein the short message service center notifies the third party service equipment of the current state information of the user equipment by sending a file carrying the current state information of the user equipment to the third party service equipment.

7. The method for getting user equipment information through short messages according to claim 1 , wherein the short message service center builds an information database in accordance with the current state information of the user equipment, and allows the third party service equipment to access the information database periodically, to notify the third party service equipment of the current state information of the user equipment.

8. The method for getting user equipment information through short messages according to claim 1 , wherein the current state information of the user equipment comprises at least one of information on position, information on power on and off state, and information on code error of the user equipment inquired.

9. The method for getting user equipment information through short messages according to claim 1 , wherein the short message service center receives the request message via a communication interface of the short message service center.

10. The method for getting user equipment information through short messages according to claim 9 , wherein the communication interface is a general service protocol interface of a signaling network, the service protocol comprising Short Message Peer to Peer protocol, UCP, Short Message Gateway Interface Protocol, Short Message Gateway Protocol, China Netcom Short Message Gateway Protocol, and China Mobile Peer to Peer protocol.

11. The method for getting user equipment information through short messages according to claim 1 , wherein the get routing message is sent with a get routing command in the form of voice.

12. A system for getting user equipment information through short messages, comprising: a short message service center, a home location register, and a third party service equipment for inquiring user equipment information,

wherein the short message service center is adapted to send a get routing message to the home location register (HLR) to get current state information of a user equipment, send a delivery message to the user equipment via a Mobile Switching Center (MSC) and receive a delivery message response containing the current state information of the user equipment from the MSC, compare the current state information contained in a get routing message response received from the HLR with the current state information contained in the delivery message response received from the user equipment to obtain the latest state information of the user equipment;

the home location register is adapted to return the get routing message response containing the current state information of the user equipment to the short message service center upon receiving the get routing message, wherein

the system further comprises: a communication interface arranged in the short message service center, adapted to receive a request message sent by the third party service equipment for inquiring the current state information of the user equipment and to send a response containing the latest state information of the user equipment to the third party service equipment.
