Message transmission method and system

Abstract

The invention discloses message transmission method and system. The method comprises the steps of encapsulating a GTPU head and a tunnel head for an uplink message through a relay base station device; sending the uplink message to a CPE (Central Processing Element); modifying the source IP address of the tunnel head into the public network IP address of the relay base station device through the CPE; sending the uplink message to DeNB; encapsulating corresponding IP+UDP+GTPU head for the uplink message through the DeNB; sending the uplink message to an SGW (Signal Gate Way); de-encapsulating the IP+UDP+GTPU head encapsulated in the uplink message through the SGW; sending the uplink message to a tunnel server through the relay base station device according to the target IP address of the tunnel head, encapsulated in the uplink message; de-encapsulating the tunnel head encapsulated in the uplink message by the relay base station device through the tunnel server; sending the uplink message to the SGW; sending the uplink message to a target device through the SGW according to the target IP address of the uplink message. According to the method and system, the difficulty at deployment for wired transmission can be solved through the wireless transmission environment, and therefore, the problem of limitation on communication in some regions is avoided, the system coverage range is expanded, and the cell throughput is increased.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and system for message transmission. Background technique [0002] Such as figure 1 As shown, it is a schematic diagram of networking of an LTE (Long Term Evolution, long-term evolution) system, which is divided into a wired side and a wireless side. The wired side includes service servers, core network, three-layer switch, transmission PTN (Packet Transport Network, packet transport network), etc., and the wireless side includes L1 / L2 (layer 1 / layer 2) protocol processing, radio frequency unit processing, UE (User Equipment , user equipment) receive and so on. [0003] In the current networking form of the LTE system, for rural or remote mountainous areas, it is impossible to build a wired transmission environment for the base station equipment, resulting in the inability of the base station equipment to connect to the core network, hindering local comm...

Problems solved by technology

[0003] In the current networking form of the LTE system, for rural or remote mountainous areas, it is impossible to build a wired transmission environment for the base station equipment, resulting in the inability of the base station equipment to connect to the core network, hindering local communication, remote areas or shadow coverage areas, or even It is a blind area, and there is a problem of poor coverage

Furthermore, in some scenarios where optical fibers cannot reach or wired backhaul construction is difficult (such as urban micro-coverage scenarios without wired backhaul, indoor office environments without room distribution deployment, residential buildings where optical fibers cannot reach households, remote suburbs or rural areas) etc.), the coverage of the macro cell signal is weak, and the deployment is not flexible
