Method for generating adjacent cells

Abstract

The invention discloses a method for generating adjacent cells. The method is as follows: loading the digital map of the planning area where the list of adjacent cells needs to be generated, and calculating the received signal levels of all cells in the area by using geographic data and base station data in the area, according to The received signal level generates the coverage map of the serving cell; in the coverage map of the serving cell, the neighbor cell list of each serving cell is generated grid by grid cycle; the signal strength and traffic volume of each neighbor cell in the handover zone are determined; The cells are sorted after the signal strength and traffic volume of the handover zone are weighted respectively, and the priority in the adjacent cell list of the serving cell is determined; according to the determined number of adjacent cells required by each serving cell, each serving A cell selects an adjacent cell. With the present invention, relatively accurate neighbor cell relations can be obtained in network planning, and then accurate cells can be selected to optimize network quality.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for generating adjacent cells. Background technique [0002] In the long-term development of mobile communication, with the continuous growth of users, the coverage area continues to expand, but the frequency resources are limited. Therefore, in order to solve the problem of the contradiction between frequency supply and demand, the concept of cellular splitting is proposed. Cell splitting refers to splitting the omnidirectional base station area into fan-shaped cells, or splitting the fan-shaped cells into several small cells. These cells are connected to each other in a honeycomb shape, and several cells form a cluster. [0003] During the call, when the mobile station enters another cell from one cell, the network can perform real-time control to switch the mobile station from the channel used by the original cell to a certain channel of the new cell, and ensu...

However, this method needs to increase the measurement information of the mobile station or the base station, resulting in a signaling burden between the mobile station and the base station

[0010] To sum up, in the current network optimization technology, there is no one that can comprehensively consider the geographical environment and signal strength to select adjacent cells, so the obtained adjacent cells are not accurate enough, so the channel of the cell may be overcrowded. When the mobile station is in the handover process, the call drop occurs due to the inaccuracy of the adjacent cell or the channel congestion of the cell, so the handover success rate is low
