A method, a system and a short message services center for sending short messages are disclosed in the present invention, belonging to the technical field of communications. The method for sending short messages includes: receiving and storing location information of a user sent by a signaling detection server, wherein, the above user is a user in a Mobile Switching Center (MSC) connected with the signaling detection server; receiving a short message sent by a calling user; determining whether the location information of a called user is stored, wherein, the location information includes the address of a first MSC in which the called user locates currently; and if the determination result is positive, sending the short message to the first MSC according to the location information of the called user. With the method provided in the present invention, when a short massage is sent, the Short Message Services Center (SMSC) can query in itself the location information of the called user and send the short message via corresponding MSC without the process of sending a Send-Routing-Information (SRI) message to query the location information of the user, and thereby considerable signaling resources are saved. |
