Embodiment Construction

[0024] As shown in the figure, the present invention selects a group of cdma20001X base stations (BSs) in a planning area i , where i is 1~9, and each base station is assumed to be divided into three sectors: BS i -1;BS i -2;BS i -3) The process of planning adjacent cells is a representative example to illustrate the method for planning adjacent cells for mobile cellular networks in the present invention.

[0025] The first step is to divide the selected sub-region into several grids of the same size on the electronic map;

[0026] The geographic location of each base station in the area corresponds to a point on the electronic map.

[0027] In the second step, the point analysis method based on coverage is carried out for each point grid to statistically analyze the candidate adjacent cell list of each sector in the area;

[0028] Monte Carlo simulation is carried out for the analysis area, and the pilot Ec / Io strength of all dot grids of each base station in its coverage...

Abstract

The invention discloses a planning method of an adjacent cell of a mobile honeycomb network: 1. A planning district is divided into a plurality of point lattices in an electric map; 2. according to each point lattice and based on the covered point analysis method, a statistic analysis of a candidate adjacent cell list of each sector in the district is done; 3. A triangulation with directions based on distance is made and the candidate adjacent cell list of each sector is got; 4. The two results of the candidate adjacent cell got from Step 2 and Step 3 are combined. According to the chosen priority, a proper cell in the candidate adjacent cells of each sector is chosen to be an adjacent cell of the cell. The invention is characterized in that the point analysis based on the coverage and the triangulation with directions based on distance are used to plan the adjacent cells at the same time, and while choosing the adjacent cells, the cells of prior strength or of prior distance can be chosen to be an objective adjacent subdistrcit, thus achieving the aim of improving the succeed ratio of the switch-in and improving the entire using efficiency of the system resources.

Description

technical field [0001] The invention relates to the field of wireless cellular networks in mobile communication, in particular to a planning method for neighboring cells used in mobile cellular networks. Background technique [0002] In a mobile cellular network, a cell that may be handed over is generally set as an adjacent cell, and the mobile station keeps measuring the power level of the adjacent cell for timely handover. Usually, there are two main factors to be considered in neighboring cell planning: one is the signal strength of the beacon channel received from other cells, and the other is the distance to the cell. For systems like cdma2000 1X and WCDMA (Wideband Code Division Multiple Access), neighboring cells are usually cells with stronger pilot frequency. However, strong pilot signals from other cells will definitely be received within the coverage of a cell. If these pilot signals are included in the list of neighboring cells as long as they are greater than ...
