Abstract

The invention discloses a micro-cell construction planning method, which comprises: determining the first pilot frequency signal to noise ratio parameter of the micro-cell and the first foreign interference factor while the micro-cell does not perform pilot frequency emission; under the condition that the micro-cell performs pilot frequency emission, measuring the second foreign interference factor of the micro-cell, and comparing the first foreign interference factor and the second foreign interference factor; under the condition that the micro-cell does not perform pilot frequency emission, measuring the second pilot frequency signal to noise ratio parameter of the macro-cell, and comparing the first pilot frequency signal to noise ratio parameter and the second pilot frequency signal to noise ratio parameter; and judging whether the micro-cell meets the request of entering the network covered by the macro-cell according to the comparing result. Applying the invention can judge whether the current configuration of the micro-cell meets the predetermined interference requirement when planning to introduce a micro-cell into a macro-cell, thereby, facilitates network planning.

Description

technical field

[0001] The present invention relates to the communication field, and in particular, relates to a planning method for construction of a micro cell, which can be applied to the scenario of adding a micro cell to a network covered by a macro cell. Background technique

[0002] A traditional cellular network is composed of a macrocell (Macrocell), and the coverage radius of each cell is mostly 0.5km to 25km. Macro cells are generally used in the initial stage of network construction to solve the problem of wide coverage under small traffic.

[0003] The coverage radius of a Microcell is about 30m to 1000m, the transmission power is relatively small, and the transmission is mainly carried out along the line of sight of the street, and the signal leakage on the roof is relatively small. Therefore, microcells are often used to increase radio coverage and eliminate "blind spots" in macrocells. The picocell with lower transmission power also exists as a supplementar...
