Problems solved by technology

[0007] The purpose of the present invention is to improve the overall performance of the wireless communication system in the heterogeneous network, make full use of the frequency band resources, and propose a low-complexity heterogeneous network cell clustering method based on the user experience rate. The increasing number of users and the distribution of network cells with ultra-dense coverage lead to more complex interference problems for users in the cell. In this environment, the cell distribution in the wireless communication system, that is, base station clustering, is optimized.

Embodiment 1

[0048] like figure 1 As shown, in this embodiment, by building a simulation scene that simulates the real environment as much as possible, a plurality of mobile communication cell models are established to form a complete cell topology, and according to the requirements of the simulation scene in the 3GPP protocol, a simulation is performed in the system. A macro cell composed of 7 cells, the base station of each cell is located in the center of the cell, the distance between stations is 500 meters, each cell is further expanded into 3 sectors, in each sector, according to Poisson distribution The principle of points, deploy small stations and users in the sector, the average number of small stations is 10, and the average number of users is 30; the location of users is evenly distributed in the network, but the distance between the location of users and the central base station is limited It is greater than 35 meters, and the distance between the user and the small station is...

Abstract

The invention relates to a heterogeneous network cell clustering method and device based on user experience speed and belongs to the technical field of radio communication. By means of K-means method, a plurality of base stations to be distributed are classified into several different types so as to meet transmission needs of different users, the base stations in the same type are high in similarity, and objects in different clusters are low in similarity; similarity is calculated by a 'central object' obtained by signal strength average of the base stations in various types. In the heterogeneous network cell clustering method, the above process is repeated until convergence, that is, until reasonable user distribution base station clusters are found. Compared with the prior art, the heterogeneous network cell clustering method has the advantages that interference to users in the intensive coverage environment is remarkably reduced, average network throughput and throughput of cell edge users are remarkably increased, and user experience quality is remarkably improved.

Description

technical field [0001] The present invention relates to a heterogeneous network cell clustering method and device, in particular to a heterogeneous network cell clustering method and device based on user experience rate, and belongs to the technical field of wireless communication. Background technique [0002] With the continuous improvement and progress of the mobile communication system, the ever-increasing user demands and business demands put forward higher requirements for the mobile network. With the commercial operation of 4G networks, users have put forward higher standards for service experience. Different from the requirements of traditional voice services and video services, users' experience in mobile services in the new environment has also risen to a new level. Such as real-time high-definition video transmission and high-speed data download and upload. To meet the ever-increasing user demand, it is necessary to increase the user peak rate on the basis of the...
