Problems solved by technology

The SS maintains the corresponding relationship between CIC and TID, but the SS does not open the interface of the corresponding relationship between CIC and TID, so the external monitoring system cannot know the corresponding relationship between CIC and TID in each call process
And when the corresponding

Embodiment Construction

[0036] The present invention is applicable to the monitoring situation of PSTN user's call connection through NGN network, which can be the call connection between PSTN user and another PSTN user through NGN network, or the call connection between PSTN user and other non-PSTN users through NGN network.

[0037] In the present invention, the PSTN system and the NGN system monitored by the monitoring equipment have calls between a large number of users in the same time period, and the monitoring equipment cannot learn the real-time change information of the corresponding relationship between the CIC and the TID from the SS, and can only learn from the detected , according to the CIC or TID detected in the call flow message, and according to the time interval for the call flow message interaction between the PSTN device and the SS device, the relationship between the CIC and the TID is judged.

[0038] Such as image 3 As shown, the method for realizing the association between th...

Abstract

The invention discloses a method and monitoring equipment for realizing association of a calling control protocol and a media control protocol. the method comprises a calling process performed by soft exchanging equipment of a NGN network aiming at public switched telephone network (PSTN) equipment; when determining the used circuit identifying code in the current calling process does not determine the calling association relation, according to the time interval of calling process message interaction carried out by the PSTN equipment and the soft equipment before the current calling process and during the calling process using the circuit identifying code, a destination node identifier is determined in each destination node identifier which is not determined the calling association relation; the destination identifier and the circuit identifying code are determined to form the calling association relation when the destination node identifier is judged to be associated with the media gateway control protocol events; the invention automatically studies the corresponding relation of CIC and TID under the condition that SS does not provide the corresponding relation of CIC and TID to a monitoring system, thus improving monitoring performance.

Description

technical field [0001] The present invention relates to the monitoring technology field of Next Generation Network (NGN for short), in particular to a method and a monitoring device for realizing the association between a call control protocol and a media control protocol. Background technique [0002] The next generation network (NGN) voice network solution based on softswitch technology is mature, but the TDM-based telephone switching network will coexist with the packet-based next generation network for a long time, and gradually evolve to NGN. [0003] figure 1 Network element structure diagram when the Public Switched Telephone Network (PSTN) is connected to the NGN network, including the Softswitch (Software Switch, SS for short), Signal Gateway (SG for short) and media gateway (Media Gateway, MG for short). The SG communicates with the SS through an Integrated Services Digital Network User Part (ISUP) protocol, and the MG communicates with the SS through a media gat...
