Method and device for detecting antenna feeder assembly reversely connected cell

Abstract

The embodiment of the invention discloses a method for detecting an antenna feeder assembly reversely connected cell, belonging to the field of wireless communication. The method comprises the following steps: in a time period to be detected, acquiring common frequency neighbor cell data and soft handover information of each cell of a base station, wherein the same frequency neighbor cell data comprises event 1A reporting frequency, event 1A reporting time, active set cell identification ID and detected set cell ID, and the soft handover information comprises time of a soft handover event, active set cell ID and target cell ID; according to the event 1A reporting frequency and a preset acquisition threshold, acquiring the current cell in optimal cells; and according to the frequency of soft handover between the current cell and all the cells of a self forward neighbor cell set and the frequency of soft handover between the current cell and all the cells of a forward neighbor cell set of a self same frequency co-base station cell, determining a cell reversely connected with the current cell, thus automatically realizing detection of antenna feeder assembly reverse connection, reducing drive test cost and improving working efficiency.

Description

[0001] This application is a divisional application of an invention patent application filed by Huawei Technologies Co., Ltd. on December 19, 2008, with the application number 200810186426.5, and the title of the invention is "A Method and Device for Detecting Cells with Inverted Antenna Feed Equipment". technical field [0002] The invention relates to the field of wireless communication, in particular to a method and a device for detecting a cell where an antenna feeder device is reversely connected. Background technique [0003] In the base station site construction and network optimization process of WCDMA (Wideband Code Division Multiple Access) mobile communication network, it is necessary to detect and optimize the radio frequency hardware equipment of a single base station site to ensure that each base station site Services such as access and calls in each cell are running normally. [0004] Among them, the reverse connection detection of antenna feeder equipment in ...

Problems solved by technology

[0006] The method provided by the prior art to transmit signals through the test terminal to observe the change of the RTWP of the cell under test and the adjacent cell, so as to detect whether the antenna feeder device of the cell under test is reversed. First, the test terminal has high requirements and requires The test terminal must transmit signals at a fixed frequency and continuously at the maximum power, and it is difficult to find a test terminal that meets the requirements at the actual test site (such as the site construction site); in addition, testers must perform a comprehensive drive test on the network, and then Carrying out special analysis on drive test data RTWP is time-consuming and labor-intensive, with high economic costs and low work efficiency; and due to the methods provided by the existing technology, there are bound to be errors due to manual detection, and some base station antenna feeder equipment may be reversed. Not detected, resulting in the coverage of the uplink being lower than the planned coverage or the relationship between adjacent cells is wrong, resulting in a decrease in the handover success rate
