Method and device for determining antenna feeder parameters

Abstract

The invention discloses a method and device for determining antenna feeder parameters, and relates to the technical field of information. The method and device can determine the accuracy of antenna feeder parameters. The method comprises the steps: correcting a wireless transmission model and determining an antenna feeder parameter of a 4G community sharing an antenna feeder with a 3G community according to the antenna feeder parameter of the 3G community in a present network; determining the antenna feeder parameter of the 4G community sharing the antenna feeder with the 3G community according to a soft handover ratio of the 3G community and a repeated recovery level, so as to achieve the control of the interference level of the 4G community; taking an independent 3G antenna feeder base station as a circle center, forming an antenna feeder cluster, and adjusting the antenna feeder parameter of the 3G community or the 4G community, so as to enable the coverage radiuses of the 3G and 4G communities in the antenna feeder cluster to be consistent. The method and device is suitable for the determining of the antenna feeder parameter of the 4G community sharing the antenna feeder with the 3G community according to the antenna feeder parameter of the 3G community.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a method and device for determining antenna feeder parameters. Background technique [0002] With the development of the third-generation mobile communication technology (English full name: Third-Generation, English abbreviation: 3G) network and the fourth-generation mobile communication technology (English full name: Fourth-Generation, English abbreviation: 4G) network development, there are Many 3G networks and 4G networks share base stations and antenna feeders. However, due to the great differences in the working standards, working frequency bands, and switching methods of 3G and 4G networks, the signal coverage of 3G networks and 4G networks will be inconsistent. , and because the coverage of the 3G network and the 4G network are inconsistent, CSFB may fail to fall back, call drops, and fail to switch. Therefore, it is necessary to determine the parameters of th...

Problems solved by technology

[0004] However, when the antenna feeder parameters are determined by simulation software and manual experience, due to the complexity of wireless signals and application scenarios, the simulation software and manual experience cannot truly reflect the actual situation of the 3G network and 4G network in the network, resulting in the determination of antenna parameters. Feedback parameters are less accurate
