A multi-system anti-interference filtering method based on digital system transmission

Abstract

The invention discloses a multisystem anti-interference filtering method based on digital system transmission. The multisystem anti-interference filtering method comprises the following specific step:S1, firstly, building a convergence layer network transmission system, an access layer network transmission system and a core layer network transmission between a core layer and a convergence layer,between the convergence layer and an access layer in an LTE transmission system, as well as between core machine rooms in a core machine room unit of the core layer respectively. The invention relatesto the technical field of network transmission. Through adoption of the multisystem anti-interference filtering method based on digital system transmission, the same anti-interference filtering system can be built among a plurality of transmission systems in order to perform integral classification control on the filtering condition among the systems, thereby reducing the data network transmission noise greatly, and preventing data chaos and disordering under severe interference. Thus, the LTE data transmission stability is ensured, and the building time of filtering instruments between LTE transmission systems is saved well, so that people can use the LTE network transmission normally.

Description

technical field [0001] The invention relates to the technical field of network transmission, in particular to a multi-system anti-interference filtering method based on digital system transmission. Background technique [0002] The LTE mobile transmission network is generally divided into three layers: the core layer, the aggregation layer and the access layer. The core layer node: refers to the mobile network service local core network equipment and the equipment room where the backbone equipment is located. The main business equipment includes various switches, core routers, and trunk lines. transmission equipment, etc. The transmission system between the core equipment rooms is defined as the core layer network, and the aggregation layer node: the aggregation equipment room dedicated to converging the access layer services. The main business equipment includes transmission network aggregation layer equipment, IP metropolitan area network aggregation node equipment, etc. ...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a multi-system anti-interference filtering method based on digital system transmission, which solves the problem of simultaneous transmission of data between multiple systems in the existing LTE system. The occurrence of signal interference between various systems will easily make the transmitted data noisy. When the interference is severe, data disorder and distortion will occur, which greatly affects the stability of LTE data transmission and cannot be established between multiple transmission systems. The same anti-jamming filtering system is used to perform overall classification control of the filtering conditions between various systems, which cannot achieve the purpose of reducing the construction cost of filtering equipment, and cannot realize the problem of saving the construction time of filtering facilities between LTE transmission systems
