Crosstalk detecting method and device

Abstract

The invention relates to the core network technical field and provides a crosstalk detecting method and a crosstalk detecting device. The objective of the invention is to solve the problem of incapability of a crosstalk detecting method to detect crosstalk faults in an IP network, wherein the crosstalk detecting method adopts a relay dial testing mode. According to the embodiment of the invention, under a crosstalk situation in which one party of a calling party and a called party hear voice communication of other people while the other party cannot hear any sound in voice communication, after it is determined that voice signal energy received by one party of a calling terminal and a called terminal is zero, whether crosstalk occurs is determined through judging whether voice features of voice signals received by the other party of the a calling terminal and the called terminal change or not, and therefore, crosstalk in the IP network can be automatically detected, and either crosstalk generated on a wireless channel between a user terminal and a wireless network or crosstalk which is generated between the wireless network and a core network and is generated by equipment of the core network itself can be detected.

Description

technical field [0001] The present invention relates to the technical field of core network, in particular to a crosstalk detection method and device. Background technique [0002] In the current communication system, there is a situation that one of the calling party or the called party hears the conversation of someone other than the other party during the call, and this situation is called crosstalk. In a call where crosstalk occurs, it is most common for one party to hear the other party while the other party cannot hear the voice. [0003] In a traditional time division multiplexing (Time Division Multiplexing, TDM) network, it is possible to detect whether there is a line error that causes crosstalk through the method of dialing the relay. However, with the introduction of softswitch architectures such as core networks and the development of IP-based networks, TDM circuits in the network are gradually replaced by IP circuits. New method to detect crosstalk in IP netw...
