Embodiment 1

[0039] This preferred embodiment provides a kind of method that the VOIP gateway equipment under NGN network carries out media capture bag, this method is by preset certain media flow information as filter condition, finds the VOIP media flow that meets the condition in the large-capacity VOIP gateway And automatically capture packets. Through this method, the media stream of a specific call can be effectively captured, and the media packet capture requirement in the practical application of the VOIP gateway can be effectively solved. The method flow of this preferred embodiment is as follows figure 2 As shown, steps S202 to S210 are included.

[0040] Step S202, setting a preset packet capture condition. After the setting is complete, the packet capture condition can be sent.

[0041] Step S204, according to the preset condition, search for media streams meeting the preset condition in all VOIP resources of the system.

[0042] Step S206, judging whether a media stream m...

Embodiment 2

[0060] This preferred embodiment provides a device for capturing packets in a VOIP gateway device according to certain preset conditions. The structural block diagram of the device is as follows Figure 5 As shown, it includes VOIP resource management module, configuration management module and packet capture module. In this preferred embodiment, the naming of each module in the device is slightly different from the above embodiment, but the same effect as the above embodiment can be obtained.

[0061] In the packet capture device of this preferred embodiment, in the process of executing the above packet capture method, each module performs different functions respectively, and each function module and process are as follows:

[0062] (1) Set certain packet capture preset conditions through the configuration management module. After the setting is completed, the configuration management module notifies the VOIP resource management module.

[0063] (2) The VOIP resource manag...

Abstract

The invention discloses a packet capture method and a packet capture device. The packet capture method comprises the following steps that: a voice over Internet protocol (VOIP) gateway device detects media streams which accord with preset packet capture conditions; and the voice over Internet protocol (VOIP) gateway device performs packet capture on detected media streams. By means of the packet capture method and the packet capture device of the invention, a problem of incapability of performing corresponding packet capture which is caused by incapability to acquire specific voice over Internet protocol (VOIP) resource information through relay information when calling does not occupy the relay information can be solved, and therefore, the packet capture can be accurately performed on the media streams when the calling does not occupy the relay information, and system performance can be improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a packet capture method and device. Background technique [0002] The Voice Over Internet Protocol (VOIP) application has developed rapidly in recent years, and has become the development direction of the telecommunications industry because of its advantages such as low price and easy and flexible implementation of value-added services. VOIP service can not only replace all the services that can be provided by the traditional Public Switched Telephone Network (PSTN) network, but also can provide many services that circuit switching cannot provide, and has a new service concept. The development of VOIP technology is revolutionary to the telecommunications industry. The traditional PSTN network is gradually being replaced by the Next Generation Network (NGN) based on the Internet Protocol (Internet Protocol, referred to as IP). In order to complete the access of PSTN equipment t...
