In addition, optionally, when the first request message is a request message for querying location information, the processing module 504 may be further specifically configured to send a user location providing request message to the MSC according to the route information after the location of the terminal device is updated, according to the trigger of the timer.
It should be noted that, when the processing module 504 is specifically configured to send a user location providing request message to the MSC according to the route information after the location of the terminal device is updated according to the trigger of the timer, the receiving module 501 is further configured to receive a response message returned by the MSC, where the response message carries the location information of the terminal device;
the sending module 502 is further configured to return a response message to the service entity, where the response message carries the location information of the terminal device, so as to ensure that the service for obtaining the location information of the terminal device is normally implemented.
Optionally, furthermore, when the first request message is an unstructured supplementary data USSD message,
the processing module 504 may be further specifically configured to send the USSD message to the MSC according to the route information updated by the location of the terminal device according to the trigger of the timer, so that the MSC sends the USSD message to the terminal device, and normal implementation of a USSD message service is ensured.
In addition, optionally, the timer starting module 503 is specifically configured to start a timer, where the timer is used to trigger processing of the first request message after a mobile switching center MSC to which a cell where the terminal device currently resides receives a location update response message.
The method comprises the steps that after a Mobile Switching Center (MSC) to which a cell where the terminal equipment resides currently belongs receives a position updating response message, processing of the first request message is triggered, and the problem that when the MSC does not receive the position updating response message and fails to activate user subscription information of the terminal equipment, a service processing request for the terminal equipment is received, so that service failure is caused is avoided.
