Description

TECHNICAL FIELD The present invention relates to the field of next generation communication networks, and in particular to a media gateway and a media resource detecting method. BACKGROUND OF THE INVENTION Next Generation Network (NGN) is a full-service network that supports IP services, intelligent, converged, manageable and operable, with IP (Internet Protocol) as the core. The next-generation network uses a separate architecture of bearer and control. Combined with the openness of IP networks and the controllability of traditional communication networks, it provides a unified architecture for inter-network convergence and provides customers with quality of service (QoS, Quality of Service) Guaranteed multimedia services. As a part of the NGN, the Media Gateway (MG) is mainly responsible for the control and management of media resources and the PSTN (Public Switched Telephone Network) to access the IP core network through trunks to complete the PSTN trunk side. Voice/fax and IP network side voice/fax conversion. The media resource functions include voice playback, MFC/DTMF/MF transceiving number, CID (Calling Index Display), and conferences. These functions mainly rely on the digital signal processor (DSP) for the analysis and processing of frequency signals, and can perform media resource functions for multiple time slots, ie, voice channels, simultaneously after multi-channel processing. However, when the user perceives that the media function is abnormal (such as broadcast voice distortion or error in sending and receiving errors) or self-checking the media resources, the maintenance personnel generally perform media function detection at the source of the media resource. FIG. 1 is a schematic structural diagram of a media gateway according to the related art. As can be seen from the figure, in the conventional method, to test each channel of the media resource unit 4, it is necessary to take the path of "media resource module - relay module external tester". The method of using the media gateway shown in FIG. 1 is as follows: Step A. The background 1 provides a human-machine dialog interface to input the media resource that needs to be detected, and the relay module 7 disconnects the service of the existing network, and the relay module 7 A special device capable of processing media functions, that is, an external tester 8 (such as a frequency analysis function or a recording function) is connected to the trunk; Step B. The control module 2 controls the DSP media to be detected by controlling the switching module 5 in the media gateway. The channel of the resource module 4 is switched to the channel corresponding to the relay module 7; Step C. Through the operation of step B, the media resource has been transmitted to the external tester 8 capable of processing the media function through the relay module 7. At this time, the maintenance personnel can read the media resource information on the specific channel on the device. And judge whether the media resource channel is abnormal or not. This traditional method of detecting media resources is necessary in the PSTN network, but it is somewhat inconvenient. In the process of detecting media resources, you need to disconnect the services of the existing network (at least temporarily disconnected), which will have certain impact on network operations. At the same time, this method to detect media resources also requires the installation of specific devices at specific locations (near the trunk), which can be difficult to detect media resources or locate faults in a complex environment. And no matter what media resources are being tested, the final stage of this method requires manual judgment. In view of the related technology, it is necessary to use external devices to detect DSP media resources, which affects the operation of the existing network services. Currently, no effective solution has been proposed.
