A method, terminal and system for e1 point-to-point communication

Abstract

The invention discloses a method, a terminal and a system for E1 point-to-point communication, which receive a first E1 message forwarded by a first CPE in a public network; and forward the first E1 message according to a preset E1 path forwarding table Forward to the corresponding second CPE, send the first E1 message to the corresponding second E1 through the second CPE; send the E1 message through the CPE, and forward it through the public network, because the CPE will A device that converts high-speed 4G or 5G signals into WiFi signals or wired network signals. Therefore, it can realize point-to-point communication of E1 messages through the wireless network. As long as there is wireless signal coverage, point-to-point communication of E1 can be realized, which is convenient for business development. 4G network or 5G network can be used instead of PSN to transmit E1 services, and the maintenance cost is low.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to an E1 point-to-point communication method, terminal and system. Background technique [0002] In 1999, RAD introduced TDM over IP technology to the market for the first time. TDM over IP technology can provide the transmission of E1 or T1 circuit services on the IP network. Compared with traditional telecommunication networks, TDM over IP technology gives full play to the bandwidth and cost advantages of data networks, and provides service providers with a simple and low-cost solution. The transition plan for the transformation from the traditional telecommunication network to the all-IP network. [0003] TDM (Time Division Multiplexing) circuit emulation gateway equipment is a product developed based on TDM over IP technology. This equipment generally has multiple E1 interfaces and is deployed on the edge of TDM network and PSN (Packet Switching Network) network. It ...

Problems solved by technology

However, these traditional applications have relatively limited requirements on the network environment. They can only rely on wired networks, and the maintenance cost is high. Once the network environment or connection requirements change, the configuration of the gateway devices at both ends must be modified accordingly.

[0004] At present, the coverage rate of 4G network in my country has reached more than 95%. The lower network delay and high peak network rate can also meet the needs of TDM circuit emulation gateway equipment intercommunication business, so 4G network is used to replace PSN to transmit E1 business It has become possible, but currently there is no effective and convenient way to realize the transmission of E1 services through 4G networks, so as to realize the transmission of E1 services through wireless networks
