Mobile communication network stereo layered laying method based on 4/5G high frequency band

Abstract

The invention relates to a mobile communication network stereo layered laying method based on a 4/5G high frequency band and belongs to the mobile communication technology field. The method comprisessteps that according to modern city structure characteristics, a coverage area of a mobile communication base station system is decomposed into individually independent stereo grids from a horizontalplane and a vertical plane, based on wireless signal line-of-sight propagation characteristics of the 4/5G high frequency band, scene distinguishing of the stereo grids is carried out, continuous identical scenes are finally merged, a city wide coverage network configuration is established, customized coverage method design for non-continuous scenes is carried out on the basis, the integral coverage scheme can be accurate to fine grids in street blocks, network coverage cost is reduced to the maximum degree, interference caused by overlapped coverage is reduced to the minimum degree, and carrier-to-interference ratio performance of the whole city network is improved to the optimum level.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a three-dimensional layered layout method of a mobile communication network based on a 4 / 5G high frequency band. Background technique [0002] In recent years, the mobile communication network in the city has undergone tremendous changes both in terms of urban structure and communication network, which has resulted in the traditional cell planning theory of mobile communication network being no longer suitable. [0003] First, with the continuous acceleration of urbanization, the architectural composition and structure of modern cities have undergone great changes. With the background of fully considering the efficiency of various urban functions, the characteristics of modern city blocks have become increasingly prominent. [0004] Second, in the field of mobile communications, with the upgrading of technology and the continuous evolution of the network,...

Problems solved by technology

[0008] However, in the development process of modern cities, there are more and more high-rise buildings, urban blocks are becoming more and more obvious, and there are more and more local traffic hotspots. In addition, with the expansion of urban areas, the terrain of urban areas has greater fluctuations. , the traditional mobile communication network structure is becoming more and more difficult to guarantee, so that in order to meet the coverage requirements of the network, the setting of the base station site is forced to become an on-demand setting rather than a structured setting. The communication network has obvious defects in the following aspects:

[0009] 1. The increase of unstructured base stations has led to the emergence of high-overlapping coverage areas in many local areas. The interference in the network in these areas continues to increase, and the difficulty of network optimization continues to increase;

[0010] 2. The resource utilization efficienc...
