Frequency point scrambling code collocation method, system and central arbitration node

Abstract

The embodiment of the invention provides a frequency point scrambling code collocation method, a frequency point scrambling code collocation system and a central arbitration node. The frequency point scrambling code collocation method comprises the following steps of: receiving a measuring report which is reported by a first femto base station and comprises measuring information, position information and priority level information of the first femto base station; and determining a frequency point and a scrambling code of the first femto base station according to the measuring information, the position information and the priority level information, wherein the measuring information comprises received signal quality information of the frequency point after the first femto base station measures according to a collocated frequency point list. According to the frequency point scrambling code collocation method, the frequency point scrambling code collocation system and the central arbitration node, adjacent femto base stations select different frequency points and scrambling codes to establish cells, so network quality degradation due to the mutual interference of the cells is avoided, and QoS of the network is ensured.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a frequency point scrambling code configuration method, system and central arbitration node. Background technique [0002] Femto base station is the mainstream technology for indoor coverage of the third generation mobile communication technology (Third Generation; 3G) network. business needs. The coverage area of ​​Femto base stations is very small, and the cell radius is generally between 20 and 50 meters. In order to meet the requirements of coverage continuity and capacity, the deployment density of Femto base stations is very high. Femto base stations generally have the ability to perceive the wireless environment, and realize the self-organizing network through the perception of the wireless environment. [0003] When Femto base stations are used for networking, each Femto base station will be configured with a frequency point list an...

AI Technical Summary

Problems solved by technology

[0006] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: the time when the Femto base stations of the same group periodically rebuild the Femto cell is consistent, so there will be multiple base stations that select the same frequency point and scrambling code The establishment of a cell affects the quality of the network
