Single Pass Detection Method

With the development and popularization of mobile communication, mobile communication has become an indispensable way of communication in the life. However, communication network faces increasing pressure, and more and more communication quality problem emerges in the communication process as the increasing of the people who use mobile communication.From the whole of mobile communication system, there are many reasons to cause the crosstalk and single pass phenomenon including: terminal, wireless network, transmission network, core network, and so on. Problems of any link in the network may lead to the appearance of crosstalk and single-pass.In the process of TD-SCDMA network maintenance, the maintenance personnel leans about the single-pass occurring in the network only through user complaints. Since the complaints habit of ordinary users is not positive, once the VIP customer complaint, this means a negative impact on the network has been occurring.Nowadays, voice single-pass in mobile communication is a very common and difficult to solve problem. Voice single-pass is a systemic problem, related to four net element including core network, transmission network, wireless network and terminal. Each net element hopes to reduce the probability of single-pass occurring.In the modern network, the customer complaints often occur. In case of complaints, single-pass phenomenon has happened a few hours, or even more than one day. However, maintenance personnel can only passively wait for complaints. Therefore, the fault already very serious when complaints occur because the ordinary users have no complains habits. It is harmful for the fault predicting and fast recovery, and has negative impact on the quality of network. So the demand of detection of speech single-pass is very appropriate for the users. With the increase of TD-SCDMA network users and the further expansion of TD network, network quality is becoming more and more attention by operators. The operators in the GSM network management also attach great importance to and at the same time have no good solution.As a result, the technical personnel urgently needs to solve one problem is that proposing a method for voice business single-pass detection, which is used to discover the single-pass phenomenon, reduce the fault handling recovery time, improve the security and stability of the voice business, improve the user experience.
