Method for eliminating interference between self-organized network base station nodes

Abstract

The invention relates to the field of mobile communication, in particular to a method for eliminating interference between self-organized network base station nodes. Each base station node detects the signal intensity of an adjacent base station node and broadcasts the signal intensity in system message, and the adjacent base station node acquires own interference degree to the base station node from the monitored system message so as to adjust own transmitting power to achieve the aim of reducing mutual interference between the base station nodes. The method does not need to establish a special physical channel between the adjacent base station nodes, and does not need to change a self-organized network architecture much, thereby simplifying the complexity of the self-organized network design and saving wireless resources of air interfaces at the same time.

Description

field of invention [0001] The invention relates to the field of mobile communication, in particular to an interference elimination method between base station nodes of an ad hoc network. Background technique [0002] In the development process of mobile communication, there have been two networking methods, one is the fixed base station networking method, which has been widely applied to the second generation mobile communication system (abbreviation: GSM) and the third generation mobile communication system. In the communication network (referred to as: 3G). Its characteristics require careful base station site selection, wireless signal coverage planning, and wireless signal interference analysis in the early stage of mobile communication network deployment, which is conducive to the improvement of the wireless performance of the entire system, but the biggest drawback of this method is the long networking cycle , the networking process is complicated, and after the base ...

Problems solved by technology

[0007] In order to solve the problems that there is interference between the various nodes of the current ad hoc network and dedicated physical channels are used between the base station nodes, the signaling control is complicated, and a large amount of air interface wireless resources are wasted, the present invention proposes an ad hoc network between base station nodes Interference elimination method, this method is mainly applicable to ad hoc networks where broadcast system messages exist, each base station node detects the signal strength of its adjacent base station nodes and broadcasts it in the system message, and the adjacent base station nodes obtain the signal strength from the monitored system message In order to reduce the mutual interference between base station nodes, adjust the transmission power of the base station itself.
