Problems solved by technology

But the core problem of this method is how to accurately determine whether the users in the community belong to the inner ring area or the outer ring area, especially when the user moves between the inner and outer ring areas, the user will switch back and forth between the inner and outer ring types , resulting in a ping-pong effect that seriously affects user and network performance

Embodiment Construction

[0034] Figure 5 is a flow chart of the user type determination method of the inner and outer rings according to an embodiment of the present invention. It should be noted that the steps described in the following method can be executed in a computer system such as a set of computer-executable instructions, and, although in Figure 5 Although a logical order is shown, in some cases the steps shown or described may be performed in an order different from that shown or described herein. Such as Figure 5 As shown, the method includes the following processing:

[0035] Step S502, after each adjacent cell base station is initialized, the division of the inner and outer ring areas and the negotiation of the outer ring frequency band resources are completed. It should be noted that it must be ensured that the frequency bands used by the outer ring areas of each adjacent cell do not interfere with each other, so that In order to effectively eliminate the interference existing betwe...

Abstract

The invention discloses a method and a system for eliminating neighbor cell interference. The method comprises the following steps of: separating an inner ring area and an outer ring area from a base station coverage area; mutually negotiating occupied frequency bands by neighbor base stations so that occupied frequency bands of respective outer ring areas are mutually different; transmitting a detecting signal to a terminal in the coverage area by the base station; judging the type of the user which corresponds to the terminal on the basis of a feedback signal generated by responding the detecting signal through the terminal, wherein the user is an inner ring user or an outer ring user; and applying the frequency band which corresponds to the type of the user by the base station on the basis of a judging result of the user type. Due to the adoption of the technical scheme of the invention, the type of a user in a cell in a WiMAX (Worldwide Interoperability for Microwave Access) common-frequency networking system can be accurately judged, particularly the ping-pong effect which is probably generated by a user positioned on an inner and outer ring boundary can be avoided and the performance of the whole network can be improved by a self-adapting threshold value adjusting algorithm.

Description

technical field [0001] The present invention relates to the field of communication, and more specifically, to a method and system for eliminating interference of adjacent cells in a WiMAX (Worldwide Interoperability for Microwave Access) network system. Background technique [0002] With the rapid development of network technology, Worldwide Interoperability for Microwave Access (referred to as WiMAX) wireless network is gradually recognized by people and has become a new 3rd generation (referred to as 3G) standard. [0003] In the WiMAX system, a terminal located in an overlapping coverage area between cells can receive downlink frame signals sent by each cell overlapping in the area. If these cells use the same frequency band for signal transmission, for the terminal, the signal sent by the base station of the cell that it does not access constitutes interference to the terminal. [0004] figure 1 It is a schematic diagram of overlapping coverage of multiple cells in the...
