Abstract

The embodiment of the invention provides a method and device for determining the uplink interference contribution degree of an interference source cell. The method for determining the uplink interference contribution degree of the interference source cell comprises the following steps: determining the interference source cell of an interfered cell and the uplink interference sampling point proportion of each interference source cell according to original data of a measurement report; and determining the uplink interference contribution degree of each interference source cell to the interferedcell according to the uplink interference sampling point proportion of each interference source cell. According to the method and the device for determining the uplink interference contribution degreeof the interference source cell provided by the embodiment of the invention, the interference source cell of the interfered cell and the uplink interference contribution degree of each interference source cell to the interfered cell are determined based on the original data of the measurement report, so that the accuracy is higher, the benefit is higher, the operation is simpler, and the user experience is not worsened.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a method and a device for determining an uplink interference contribution degree of an interference source cell. Background technique [0002] With the gradual increase of the LTE network load, the interference within the LTE network is gradually apparent. How to accurately judge that the uplink interference is generated by users in the network and determine the information of neighboring cells that cause the interference has become an urgent problem to be solved in the current network development. Problems such as unreasonable power setting, unreasonable base station coverage area, and high network load will all lead to an increase in the intensity of uplink interference in the network. Therefore, the cell needs to be optimized. [0003] In the prior art, before performing cell optimization, the interfering source cell is sorted out throu...

AI Technical Summary

Problems solved by technology

Affected by the cell handover request and the configuration relationship information of the adjacent cells of the cell and it is impossible to determine the degree of overlapping coverage of the cell caused by the handover cell, the determination of the interference source cell is not accurate and effective, and the difference is accurately determined; only based on the handover request existing in the edge area of ​​​​the cell handover and the measurement report to determine the interference source cell, but for other areas covered by the cell and the cell that has not received the measurement report, it is impossible to judge whether it is the interference source cell, which has great limitations; after combing the interference information of the neighboring cells and determining the interference source cell It is necessary to close the station (power reduction) of the interference source cell to determine the uplink interference contribution of the interference source cell to the disturbed cell, which has a great impact on the existing network, easily leads to poor user experience, and easily causes user complaints
