Method of detecting identical scrambling code interference and detection device

Abstract

The invention relates to a method of detecting identical scrambling code interference. The method comprises steps of: acquiring multiple pieces of identical frequency measurement information from a terminal, wherein the identical frequency measurement information comprises main scrambling codes of two adjacent cells and clock offset of two adjacent cells, and the main scrambling codes of two adjacent cells in the identical frequency measurement information are a main scrambling code pair; selecting two pieces of identical frequency measurement information from multiple pieces of identical frequency measurement information; when the two pieces of identical frequency measurement information have identical main scrambling code pair and a difference of clock offsets included in the two piecesof identical frequency measurement information is greater than or equal to a preset threshold, determining the main scrambling code pairs of the two pieces of identical frequency measurement information as to-be-processed main scrambling code pairs; and when at least two to-be-processed main scrambling code pairs comprise a target main scrambling code, determining that identical scrambling code interference exists in a cell corresponding to the target main scrambling code. According to the method, the cell with identical scrambling code interference can be detected rapidly and accurately. Theinvention further provides a detection device implementing the method.

Description

technical field [0001] The present application relates to the communication field, and in particular to a method and a detection device for detecting co-scrambling code interference. Background technique [0002] In a mobile communication system, the primary scrambling code is an identifier used to distinguish cells. The number of primary scrambling codes is limited. When cells are densely populated, some cells have the same primary scrambling code. The signals of cells with the same primary scrambling code interfere with each other, which is called co-scrambling code interference. [0003] In the prior art, the method for detecting co-scrambling code interference is roughly as follows: obtain the same-frequency neighbor cell list of A cell, and select a neighboring cell, such as B cell, from the same-frequency neighbor cell list. If the primary scrambling code of cell C is the same as the primary scrambling code of cell A in the same-frequency neighbor cell list of cell B,...

AI Technical Summary

Problems solved by technology

[0004] In practical applications, the cell that triggers co-scrambling code interference may not be recorded in the current co-frequency neighboring cell list due to reasons such as false base stations or the list of co-frequency neighboring cells is not updated in time, so it is difficult to determine the existence of co-scrambling code interfering cell
