Embodiment Construction

[0013] Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the present invention is described in further detail:

[0014] The flow of a method for detecting pilot pollution in an embodiment of the present invention is as follows: figure 1 As shown, firstly, according to the RSCP of each cell, it is judged whether there is pilot pollution in the network; if there is, then according to the primary scrambling code of the cell, and the configuration information and geographic information of each cell, the pilot pollution group information is obtained; then according to the base station The power difference between the transmitting power of the user equipment and the receiving power of the user equipment is used to obtain the position of the pilot pollution point. refer to figure 1 After setting the absolute threshold value ABSOLUTE_THRESHOLD, the relative threshold value RELATIVE_THRESHOLD and the cell number threshold value NUMBER_THRESHOLD ...

Abstract

This invention discloses a method for testing pollution of pilot frequency including the following steps: first of all judging if there is pilot pollution in a network according to RSCP of local areas, if so, obtaining pilot pollution set information based on primary harass codes, configured information and geographical information of the areas, then obtaining positions of pilot pollution points based on the difference of the emission frequency of the base station and receiving power of user equipment. This invention also discloses a device for testing pilot pollution.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and device for detecting pilot pollution. Background technique [0002] With the rapid development of wireless communication technology, CDMA (Code Division Multiple Access, Code Division Multiple Access) technology is widely used. CDMA is a mobile communication technology designed for the requirements of large capacity, high quality, integrated services, soft handover, and international roaming required by modern mobile communication networks. A high-speed pseudo-random code with a bandwidth much larger than the signal bandwidth is used for modulation, so that the bandwidth of the original data signal is expanded, and then modulated by the carrier and sent out. The receiving end uses the same pseudo-random code to perform correlation processing with the received bandwidth signal, and converts the broadband signal into a narrowband signal of the original ...
