Embodiment Construction

[0040] The core idea of ​​the present invention is: before the call starts, the signaling tracking task is initiated by the TG, and the telephone number in the tracking task is reported to the MGC through the Notify command carrying the extension package. When the phone numbers in the TG are the same, the description of the ADD command (call establishment) issued by the MGC carries an extension packet, and the number is issued and marked as the caller (called) The phone number in the extension package is compared with the phone number of the tracking task. If they are consistent, the TRUNK and the RTP in the same context will be tracked; when the tracking task ends, it will also be initiated from the TG and reported to the MGC through the Notify command, and the MGC will cancel the tracking task. The number-related TRUNK / RTP description extension package saves signaling text resources. At the same time, this scheme also applies to AG.

Abstract

The invention discloses a method for processing signaling tracing on a media gateway according to numbers and a system thereof. The system comprises MG and MGC. The corresponding method comprises the following steps:1) MG establishes a tracing task according to the number, and reports the number in the task to the MGC; 2) MGC initiates a calling service and issues a command of establishing calling to the MG, if a calling / called telephone number which is called currently accords with the number in the tracing task, the number is carried in a destination node description of the command; 3) the MG determines whether or not the number is carried in the destination node description establishing the calling command, and the number accords with the number in the tracing task, if so, the destination node and context thereof are brought into a tracing range and are traced. By adopting the method, the MG can actively initiate / delete the signaling tracing flow; unnecessary expansion pack can be deleted in related signaling when no signaling tracing task is executed, thereby reducing redundant description; meanwhile, calling and called telephone numbers in the same gateway can be traced at the same time.

Description

technical field [0001] The invention relates to a next-generation network media gateway, in particular to a method and system for the media gateway to track signaling by number. Background technique [0002] The next generation network (Next Generation Network, NGN) adopts the SoftSwitch technology that separates service control and bearer media, and the SoftSwitch equipment operates through control protocols such as H.248 / Media Gateway Control Protocol (MGCP) Media Gateway (Medium Gateway, MG). [0003] When an exception occurs during the call, such as establishment failure, it is necessary to track the H.248 signaling process of the call, so as to help locate and solve the problem through the analysis of its interaction process and resource operation. In practical applications, the number of simultaneous calls on each MG is huge, and it is difficult to separate them. It is necessary to set filter conditions to track the corresponding resources of individual numbers. [0...
