A signal conflict detection method, detection method and device

Abstract

The embodiment of the invention provides a signal collision detection method, a detection method and a detection device, which relate to the field of communication and have the advantages of increasing the accuracy of the signal collision detection and having good timeliness. The signal collision detection method comprises the following steps of: obtaining at least two load fan marks which are suspected to be signal collision and a medium load fan mark; obtaining first PN (Pseudo-Noise) codes of at least two load fans and a medium PN code of a medium load fan; receiving a soft handoff request from UE (User Equipment); sending a detection request to the at least two load fans when a PN code carried in the soft handoff request comprising the first PN codes and the medium PN code is judged, and thus respectively capturing reverse leading signals of the UE in reverse business links of the at least two load fans after the reverse business links between the at least two load fans and the UE are created by the at least two load fans; and determining that the signal collision exists between the load fans corresponding to the at least two reverse leading signals if the at least two reverse leading signals are received within a preset period.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to a signal conflict detection method, detection method and device. Background technique [0002] In the communication network, the user equipment distinguishes different carrier fans according to the PN (Pseudo-Noise) code and frequency. According to the agreement, a maximum of 512 PN codes can be used in the same communication network. According to the existing communication network In terms of the actual situation, fewer PN codes can be used. [0003] With the growth of business traffic and the number of user equipment year by year, on the one hand, the site sites are becoming more and more dense, which leads to more and more serious PN code multiplexing. The existing communication network has been expanded many times after adding stations, especially flower arrangement expansion. , The entire network PN code configuration is rather chaotic; on the other hand, the geomorphology of ...

Problems solved by technology

[0003] With the increase of business traffic and the number of user equipments year by year, on the one hand, the site sites are becoming more and more dense, which leads to more and more serious PN code reuse. , the PN code configuration of the whole network is relatively chaotic; on the other hand, the landforms of each area of ​​the city are very different, and with the change of civil construction year by year, the propagation path of the wireless signal in the air is complex and changeable, and the coverage conflict of the carrier fans using the same PN code The probability of occurrence is greatly increased

[0004] However, most of the existing technologies use network planning means to prevent coverage conflicts of carriers using the same PN code, which inevitably results in low accuracy and poor timeliness of signal conflict detection
