Abstract: A network capable of M3UA-based networking, an apparatus, and a message transfer method are disclosed herein. The network includes: an IPSTP, configured to: perform signaling interworking with an IPSEP and/or other IPSTPs in the network, and maintain routes dynamically; and an IPSEP, configured to perform signaling interworking with the IPSTP.

Abstract: The invention discloses a method for reducing service loss in interworking between SS7 signaling network and M3UA. In the method, when state of an M3UA ASP-related signaling point changes, the SS7 signaling network may be notified by using messages defined in existing protocols or other messages. Thus, when performing service interworking with M3UA, the SS7 signaling network determines whether service interaction may be performed with M3UA in accordance with the state of current ASP-related signaling point. If the current ASP-related signaling point is unavailable, the SS7 signaling network will not perform service interaction. As a result, the service loss in interworking between SS7 signaling network and M3UA may be reduced without any affect on the normal service interworking between SS7 signaling network and M3UA. In addition, the method may conform to existing protocol standards, and implemented in a simple and easy way.

Abstract: A method for transmitting an SUA signaling network management message includes: upon the determination that the received signaling network management message is an SUA signaling network management message and the signaling point with a changed state is an IP signaling point according to the address information in the SUA signaling network management message, storing the changed state information of the IP signaling point locally at the first SUA relay; converting the SUA signaling network management message into an SCCP signaling network management message upon the determination that the sub-networks connected with the first SUA relay include at least one traditional telecommunication signaling network, and transmitting the SCCP signaling network management message to the at least one traditional telecommunication signaling network.
