Title: METHOD AND SYSTEM FOR SENDING SHORT MESSAGE
Abstract:
The present invention provides a method and system for sending a short message. The method comprises: a short messaging service - service center (SMS-SC) sending a short message to a short messaging service - gateway mobile switching center (SMS-GMSC), and after the SMS-GMSC sends the short message to a mobile management entity (MME), the MME sending a failure report to the SMS-GMSC when the MME detects that a terminal is unreachable (S202); the SMS-GMSC receiving the sent failure report and sending a short-message sending status message to a home subscriber server (HSS), and the HSS setting waiting data according to the short-message sending status message (S204); upon detecting that the terminal switches from unreachable to reachable, the MME notifying the HSS that the terminal is reachable (S206); upon knowing that the terminal is reachable, the HSS sending, according to the waiting data, a warning message to notify the SMS-SC that the terminal is reachable, and upon knowing that the terminal is reachable again, the SMS-SC sending the short message again (S208). By means of the solution, a short message service can also be received in an area covered only by a packet switched network.
