Home base station interference management system and method

Abstract

The invention discloses a home base station interference management system relating to the technical field of home base stations and comprising a home base station security gateway and a plurality of home base stations. The home base station interference management system also comprises a home base station management device, wherein the home base stations are connected with the home base station management device through the home base station security gateway and used for uploading base station information to the home base station management device, the home base station management device is used for distributing configuration information to the home base stations according to the base station information to ensure that the interference of the home base stations with adjacent cells is minimized during working, and the configuration information comprises resources required by the operation of the home base stations and relevant control signalings. The invention also discloses a home base station interference management method. According to the invention, the problem of interference between a macro cell and the home base stations and among the base stations is solved.

Description

technical field [0001] The present invention relates to the technical field of home base stations, in particular to a home base station interference management system and method. Background technique [0002] While the femtocell provides effective coverage for clients, it also radiates to adjacent houses and outdoors, causing interference. Therefore, considering that femtocells are deployed within the coverage area of ​​existing macrocells, they may cause strong degradation of macrocell performance. In addition, the deployment of new femtocells also disrupts the normal operation of existing femtocells. Therefore, in order to introduce the macro cell dead zone (dead zone, which refers to the geographical area where the home base station interferes too much, making it impossible for macro cellular network users to receive signals correctly) area after the introduction of the femtocell, and to successfully deploy the femtocell network, it is necessary to introduce interference...

AI Technical Summary

Problems solved by technology

[0010] First of all, it either only provides a solution for the interference between femtocells and macrocell base stations, or only provides a solution for the interference between femtocells, and fails to combine the two forms of interference for consideration

[0011] Secondly, the method that can comprehensively consider the above two solutions often requires the home base station to have positioning or sensing functions, does not have enough flexibility, and requires completely different planning of resources on the uplink and downlink

[0012] Again, the current resource allocation schemes rarely take into account the special user behavior characteristics of the home base station. Since each home base station serves a limited number of users, the It is possible to track and summarize user behavior within a short period of time, and it can be integrated into the resource management framework to better support the service quality requirements of femtocell users
