Embodiment Construction

[0094] figure 1 It is a flowchart of an embodiment of the power control method of the present invention, such as figure 1 As shown, the method of the present embodiment includes:

[0095] Step 101. According to the obtained level information and quality information in multiple measurement reports (Measurement Report; MR) of each cell under the base station controller (Base Station Controller; BSC for short), obtain the Level and quality distribution, and according to the level and quality distribution of each cell, obtain the level and quality relationship curve of each cell.

[0096] In this embodiment, the MR may further include a timing advance (Timing Advance; TA for short) and power.

[0097] Step 102 , according to the level-quality relationship curve of each cell, perform scene division for each cell, and obtain multiple scene categories and the level-quality relationship curve of each interference scene.

[0098] Step 103, according to the level and quality distribu...

Abstract

The invention provides a power control method and a device. The method comprises steps: a level and quality relationship curve of each community can be obtained according to the obtained level information and the quality information in multiple MRs of each community in BSC; according to the level and quality relationship curve of each community, scene partitioning is carried out on each community to obtain multiple scene types and a level and quality relationship curve of each interference scene; according to the level and quality relationship curve of each community, level and quality distribution of each interference scene can be obtained; according to the level and quality relationship curve of each interference scene and the level and quality distribution, a first power control parameter group of each interference scene can be obtained; and according to the first power control parameter group of each interference scene and the pre-configured second power control parameter group, power control is carried out on each community in each interference scene.

Description

technical field [0001] The present invention relates to communication technology, in particular to a power control method and device. Background technique [0002] The Global System of Mobile communication (GSM) communication system network structure is complex, and its structural characteristics are mainly: small station spacing, high frequency allocation and high business load, etc., and these characteristics lead to very serious interference in the network, especially The distribution cells with serious uplink / downlink interference in many areas account for a very large proportion, and the interference areas are concentrated. [0003] At present, the main method to reduce intra-network interference is: through uniform configuration of power parameters, power control is performed on cells to improve the increase in network noise floor caused by traffic, thereby reducing intra-network interference and improving network carrying capacity. However, for a cell with a relative...
