Channel protection method of looped network system with IP RAN (Internet Protocol-Radio Access Network) forward compatible with MSTP (Multi-Service Transport Platform)

Abstract

The invention relates to a channel protection method of a looped network system with IP RAN (Internet Protocol-Radio Access Network) forward compatible with MSTP (Multi-Service Transport Platform). If a fault occurs in an IP RAN network, the bidirectional forwarding detection conversation of an IP RAN equipment host node stays in a failure state, IP RAN equipment compatible with MSTP businesses converts the failure state of the PW (Pseudo-Wire) layer bidirectional forwarding detection conversation into a channel alarm indication signal of MSTP at a butting position, and MSTP equipment carries out concurrent transmitting and selective receiving protection switch on channels. If the fault occurs in an MSTP network, the MSTP equipment at both ends of a fault point respectively insert the channel alarm indication signal to the downstream till the butting position between the MSTP network and the IP RAN network; and at the butting position, the IP RAN equipment compatible with the MSTP businesses stops sending pseudo-wire bidirectional forwarding detection conversation frames, and the IP RAN equipment host node carries out the concurrent transmitting and selective receiving protection switch on the channels. The invention realizes the channel protection of the looped network system with IP RAN forward compatible with MSTP.

AI Technical Summary

Benefits of technology

This technology allows for compatibility between two networks by converting signals from one into another based on certain criteria like protocols or ports used during communication sessions. When there's an issue where this happens, it sends out warning messages indicating potential issues before they affect any connected devices being served over these networks. These warnings help prevent damage caused by failures such as faulty connections or poor performance due to congestion.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the performance and reliability of Internet Protocol Radio Service Base Stations (IPRSAs) when upgraded from one mode to another mode due to their unique characteristics such as being able to support both voice over internet protocol (VoIPI)-Mobile Spanning Tree Partnership Group-2 (MSCT2) and General Packet Exchange Carrier Grade-3 (GECC)) signals without compromising its original function. Additionally, there may exist other types of telecom Services like Private Line Trunkings (PTT) which require higher levels of redundancy than what they were initially designed for.
