Method for generating adjacent cells

Abstract

The present invention discloses a method of generating adjacent district, the method is as follows: Load the digital map of planning district that need generate the list of adjacent district, then calculate the power of the receiving signal with the use of region geographic data and the data of base stations, and then generate the covering map of service district according to the power of the receiving signal; Generate the adjacent district list of each service district grid by grid, in the covering map of the service district; Determine the signal intensity and telephone traffic of each adjacent district in the switching band; Sort each adjacent district by the weighting value of the signal intensity and telephone traffic in the switching band, and then determine the priority of this service area in the list of adjacent districts; choose adjacent district for each service area, in accordance with the number of adjacent districts required by each service district. With the use of this invention, the relationship of adjacent area could be relatively accurate achieved in the network planning, so precise district would be chosen and network quality would be optimized.

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
