Abstract:
1. A method for reducing service loss in interworking between a Signaling System 7 (SS7) signaling network and an Internet Protocol (IP) domain of Message Transfer Part 3 User Adaptation Layer (M3UA), comprising: determining, by a Signaling Gateway (SG), whether there is a state change of a M3UA signaling point, wherein the SG is coupled between the SS7 signaling network and the IP domain of M3UA; analyzing and obtaining, by the SG, a content of the state change of the M3UA signaling point, wherein the content of the state change of the M3UA signaling point includes an Application Server Process (ASP)-related signaling point having a failure or being unavailable, the ASP-related signaling point being recovered from a failure or being available, the ASP-related signaling point being congested, or an upper layer service user of the ASP-related signaling point having a failure or being unavailable; and sending, by the SG, a message indicating the content of the state change of the M3UA signaling point to the SS7 signaling network in accordance with the content of the state change of the M3UA signaling point, to enable a SS7 signaling point of the SS7 signaling network to determine whether to perform service interaction with the ASP-related signaling point according to the message.
