Notification Detecting System In Mobile Network

At present, a time when the peak of the development of mobile communications, expanding network capacity, more frequent changes in the network, the requirements of network maintenance higher and higher. Frequent changes in network notification sounds as if there are problems of network resources, not only brought risks to the call quality and may cause various types of emergency failures, effect the use of sound to the user and the company's revenue. How the quality of the whole Netcom Concert rapid assessment found that the existing network problems, and how to improve maintenance staff to handle notification The efficiency of audio failure, as needed to solve the problem at the present stage.During routine maintenance work, often need to inform the tone of the exchange bureau to monitor the test, to assess the performance of the notification quality. Monitoring instructions through the manual input, low efficiency and there are subjective, are increasingly unable to meet the relay circuit quality assessment work requirements. There is not good automatic notification sound quality assessment tools at home and abroad.PESQ is the most widely used and is has been considered the most accurate and reliable method of measuring voice quality, as measured by PESQ voice quality is a result of the output value in [-0.5 to 4.5] between the scores, the higher the scoreshows Better voice quality.As a project engineer, I companies in a number of technical personnel within the organization for the Ericsson core network switches, design and construction of a set of automatic verification system notification sound, PESQ technology will mature to the notification tone detection, greatly reduce the maintenance workload and improve work efficiency.
