[0029] Wherein, the neighbor cell interference information includes the identifier of each base station, the neighbor cell identifier of each base station, and the interference degree value of each base station being interfered by the neighbor cell corresponding to the neighbor cell identifier.

[0030] Specifically, in step 101, the manner of obtaining the interference information of the neighboring cell of the base station includes but is not limited to:

[0031] The first way: receiving the neighbor cell interference information reported by the base station, wherein the neighbor cell interference information includes the base station identity, the neighbor cell identity, and the int...

Embodiment 2

[0076] Such as image 3 As shown, it is a schematic flowchart of a method for coordinating and controlling interference of base stations in a cluster cell according to Embodiment 2 of the present invention. The solution of Embodiment 2 of the present invention is based on Embodiment 1 of the present invention. The method include:

[0077] Step 201: When the set time period for interference coordination arrives, select a base station in the cluster cell.

[0078] Specifically, in step 201, the method for selecting a base station in the cluster cell includes:

[0079] First, load information reported by each base station in the cluster cell is received.

[0080] Specifically, each base station in the cluster cell reports load information in real time, or periodically reports load information, which is not limited here.

[0081] It should be noted that the period for the base station to periodically report the load information is shorter than the set time period for interferen...

Abstract

The invention discloses a method for performing interference coordination control on a cell, and equipment thereof. The method comprises the steps of: acquiring adjacent-cell interference information of a plurality of base stations, wherein the adjacent-cell interference information comprises a mark of each base station, an adjacent-cell mark of each base station, and an interference degree value of each base station by the adjacent-cell interference which corresponds with the adjacent-cell interference; performing clustering processing on the base stations which acquire the adjacent-cell interference information according to the interference degree value of each base station by the adjacent-cell interference which corresponds with the adjacent-cell interference by means of a clustering algorithm; and performing interference coordination control on obtained cluster cells. Thus the base stations with relatively high interference degrees are divided into cluster cells, and interference coordination control is performed on the obtained cluster cells, thereby ensuring resource distribution optimization in the cluster cells, improving interference coordination efficiency, reducing signaling transmission frequency and number between network elements in the system, and saving network signaling cost.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and equipment for coordinating and controlling interference of a cell. Background technique [0002] LTE (Long Term Evolution, long-term evolution), as the wireless access system of the next-generation mobile communication network, has the advantages of large bandwidth, high speed, and low delay, and brings excellent mobile Internet experience to users. [0003] In order to improve spectrum utilization, the LTE system adopts the same-frequency networking method, but this same-frequency networking method causes serious interference between users in adjacent cells, resulting in poor performance of cell edge users. In order to suppress user interference between adjacent cells, the LTE system adopts Inter-Cell Interference Coordination (ICIC, Inter-Cell Interference Coordination) technology. [0004] Such as figure 1 Shown is a schematic structural diagram of ...
