Abstract

The invention provides a method and device for planning frequency and scrambling codes. The method comprises the following steps of: acquiring network parameter information and sweep frequency data in a planning region; constructing an interference matrix according to the network parameter information and the sweep frequency data, wherein the interference matrix comprises a same-frequency interference matrix and a scrambling code correlation matrix; distributing frequencies for each cell in the planning region according to the same-frequency interference matrix, and distributing scrambling codes for each cell in the planning region according to the scrambling code correlation matrix. By applying the scheme of the invention, the accuracy of frequency and scrambling code planning can be improved, namely, a frequency and scrambling code distribution mode with optimal overall interference level of the network can be acquired, so that the network quality and the user experience can be improved.

Description

technical field

[0001] The invention relates to mobile communication technology, in particular to a frequency and scrambling code planning method and device. Background technique

[0002] In a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA, Time Division-Synchronous Code Division Multiple Access) network, due to limited frequency resources, co-frequency networking is unavoidable. Specifically, in the TD-SCDMA network, the available frequency band is 15M bandwidth, and the available frequency points are only 9. Considering the indoor reserved frequency points, the current network frequency planning scheme mostly adopts multi-carrier same-frequency and different-frequency joint networking In this way, it is inevitable that the main carrier of the main serving cell and the surrounding neighboring cells will have the same frequency, which will lead to the same frequency interference between the cells. Therefore, reasonable frequency planning is required. [0...
