Embodiment Construction

[0014] The method for estimating the sector capacity of the mobile communication system provided by the invention is suitable for estimating the sector capacity in the mixed state of multiple services, and solves the problem of inaccurate estimation of the sector capacity of the mobile communication system in the prior art. The following embodiments are described by taking the TD-SCDMA system as an example. Of course, the embodiments of the present invention can be applied to network planning of other mobile communication systems.

[0015] Embodiment 1 of the present invention provides a method for estimating sector capacity of a TD-SCDMA system, specifically comprising steps:

[0016] S101. Obtain the total number of base stations in the area, where the number of base stations is determined by the link budget;

[0017] Link budget is the calculation of various losses and gains on a communication link. Through the investigation and analysis of various influencing factors in t...

Abstract

The invention discloses a method for estimating the sector capacity of a mobile communication system. The method comprises the steps as follows: the average business volume corresponding to each business in each sector in an area is determined; the blocking probability value of each business in the sector is determined; and when at least one business blocking probability value in the blocking probability value of each business in the sector is not smaller than a set specified value, a fixed amount of basic source units are added to the preset average sector capacity, the average sector capacity in which a fixed amount of basic source units are added returns to continuously execute treatment to determine the blocking probability value of each business, the execution is carried out until the blocking probability value of each business in the sector is smaller than the set specified value, and the sector capacity is determined according to the average sector capacity in which a fixed amount of basic source units are added. The invention solves the problem that the sector capacity of the mobile communication system is not estimated accurately in the prior art.

Description

technical field [0001] The invention relates to the technical field of mobile communication network planning, in particular to a method and device for estimating sector capacity of a mobile communication system. Background technique [0002] In the traditional voice-only wireless communication network, according to the uplink and downlink capacity of each cell in the wireless network, the maximum number of channels that each cell can support can be calculated, and the capacity of each cell can be easily estimated according to the erl-B model. traffic volume. [0003] However, in the TD-SCDMA system, due to the existence of various services including voice services, because the service rates of different services and the required Eb / No are different, the impact on the system load and the consumption of base station resources are also different. Estimates of cell capacity obviously cannot simply follow the estimation method in the pure voice network. The system capacity esti...
