Abstract: A method for transmitting the SUA signaling network management message is provided, the situation of the network signaling point state changing is denoted by the said SUA signaling network management message. The method includes: when the received signaling network management message is confirmed to the SUA signaling network management message and the signaling point whose state has changed is judged to an IP signaling point according to the address information in the said SUA signaling network management message, the state information of the IP signaling point having changed is stored locally in the first SUA relay; when at least one traditional telecommunication signaling network included in the sub-network connecting with the said first SUA relay is confirmed, the said SUA signaling network management message is converted into the SCCP signaling network management message and the SCCP signaling network management message is transmitted to the said at least one traditional telecommunication signaling network. By using the method, after the state of the IP signaling point in the IP signaling network side of the SUA relay having changed, the traditional telecommunication signaling network can acquire the state information of the IP signaling point having changed. A SUA relay is also provided.

Abstract: A fast convergence method of point to point services and the provider edge device thereof. The method comprises: a. setting the route information of at least two tunnels whose start node is the PE the farend CE dual-attached to and the end node is the PE the farend CE connected with in the PE the farend CE dual-attached to; b. detecting the status of the tunnel to obtain the tunnel status information; c. the PE the farend CE dual-attached to obtains available route information according to the tunnel status information and the preset route information of the at least two tunnels and forwards the services according to the available route information. The PE the farend CE dual-attached to of present invention can forward the services directly according to the preset route information of other tunnels when the tunnel is unavailable such as the end node of the tunnel occurs abnormal, so that the route reselection is avoided, the convergence speed of the point to point services is increased and the reliability of the services is improved.
