The present disclosure discloses a method for short message signaling intercommunication and a short message service center (SMSC), relating to the field of mobile number portability (MNP) service in mobile communications technology, and applying to solve the problem in the prior art that the process of the short message signaling intercommunication cannot be applied to the MNP service. The method includes: step, the SMSC of a sending network receives a mobile original (MO) message from a mobile switching center (MSC) of the sending network, wherein the MO message includes the mobile directory number (MDN) of a receiving terminal (); step, according to the MDN of the receiving terminal, the SMSC of the sending network inquires of the number portability data base (NPDB) about the current home network of the receiving terminal, and acquires the information of the current home network of the receiving terminal (); and step, according to the information of the current home network of the receiving terminal, the SMSC of the sending network transmits the mobile terminal (MT) message () generated according to the MO message to the MSC of the current home network of the receiving terminal. The present disclosure is applied to the short message signaling intercommunication in the mobile number portability service.

Method for short message signaling intercommunication and short message service center

The present invention discloses a method for controlling short message terminated flow, including: a process that a SMS message center setting a terminated flow control threshold of a mobile switching center and controlling the terminated flow according to the threshold; the process including a step of the SMS message center dynamically setting the terminated flow control threshold according to the operation blocking level of short message service of the mobile switching center. The present invention also discloses a system for controlling short message terminated flow. With the SMS message center dynamically adjusting the terminated flow control threshold according to the load condition of the short message service of the mobile switching center, the present invention achieves adaptive terminated flow control of the mobile switching center and improves effectiveness of the flow control.
