Research On Crosstalk And Mute Problems In GSM Network Level

Mobile communication has become a necessary communication style in common life along with the development and popularization of GSM mobile communication. At the same time, more and more speech quality problems in communication arise due to constantly increasing of consumer number. Crosstalk and mute in communication make consumers can not communicate normally. They are serious speech problems. Crosstalk is a kind of interference in communication. Consumers can hear a third party voice or some cacophony in communication. Mute always indicates that only one side can receive voice while another side can not receive. Crosstalk and mute bring bad influence to voice communication. Therefore, it is necessary to reduce this kind of problems for ensuring communication quality.There are a lot of causes to result crosstalk and mute according to the whole GSM Mobile communication system. Voice communication indicates process of voice data switch in networks. In this process, no mater which part of network switch abnormally can possibly result in crosstalk and mute. The article spreads from GSM network level and gives three point of view:1. The main reason to cause crosstalk is route failure in network, namely, switch failure in network.2. Mute always appears along with crosstalk.3. Another reason of mute is congestion of networks. Congestion of networks can result in block of the voice link and data lose.The article also introduces the development direction of voice communication - VOIP technology. According to transport protocol of VOIP, the article analyzes crosstalk and mute in VOIP voice communication, and expatiates network congestion, network delay and network security are possibly the causes of crosstalk and mute.At last, the article gives the way to reduce crosstalk and mute in the side of communication engineering. One way to reduce crosstalk and mute is network optimization. Another way to reduce crosstalk and mute is to detect crosstalk and mute across detect function of Base Station. It can find crosstalk and mute problems as early as possible. Then people can solve the problems as soon as possible.
