Network planning method and apparatus

Abstract

The invention, which relates to the communication network field, provides a network planning method and apparatus. The method comprises the following steps that: a wireless utilization rate and telephone traffic of each cell are obtained; when the wireless utilization rate of a target cell is larger than a wireless utilization rate threshold and the telephone traffic of the target cell is larger than a telephone traffic threshold, if the carrier frequency number of the base station where the target cell is located does not reach a carrier frequency upper limit, the carrier waves of the base station where the target cell is located are increased; and when the wireless utilization rate of the target cell is larger than the wireless utilization rate threshold and the telephone traffic of the target cell is larger than the telephone traffic threshold, if the carrier frequency number of the base station where the target cell is located reaches the carrier frequency upper limit, a new base station is added. With the method and apparatus, problems existing in the cell can be diagnosed and reasonable planning can be carried out, thereby improving the service quality of the cell. In addition, the whole scheme can be implemented automatically without the need to invest manpower, thereby improving the network planning efficiency.

Description

technical field [0001] The invention relates to the field of communication networks, in particular to a network planning method and device. Background technique [0002] During the construction of wireless mobile communication networks (such as GSM, TD-SCDMA, WCDMA, CDMA2000, etc.), due to the differences between the actual situation and the plan, the regular flow of population caused by urban construction, and the relocation and adjustment of site sites, the traffic There are changes in the traffic hotspots in the network. Traffic refers to the voice traffic in the CS domain of circuit switching and the data traffic (or equivalent traffic) in the PS domain of packet switching. Traffic is an important factor to be considered in network planning and construction. Therefore, how to plan a site that can absorb traffic and how to evaluate the traffic absorption effect of the site and the impact on the existing network are the key and difficult points in the current network plan...

AI Technical Summary

Problems solved by technology

[0004] 1. The planners have no quantitative evaluation method for the traffic absorption after the planning station is completed. They only rely on personal experience and intuition to judge, and cannot accurately give how much traffic can be absorbed after the planning station is completed and how many blocks need to be configured in the community. Carrier frequency, so the traffic absorption after the planned station is built is not ideal, which leads to the re-planning of the new station, resulting in waste of resources;

[0005] 2. After the site is opened, the background performance index monitoring method has obvious lag, which is of little significance for the guidance and reference of site planning, and has a large demand for manpower and material resources;

[0006] 3. High-traffic areas are often densely populated areas, so there are common problems such as dense sites, diverse terrain and buildings, and complex wireless environments. Planning stations to solve traffic absorption will lead to deterioration of the network structure in this area, which cannot be predicted in advance and evaluate
