Problems solved by technology

The H.323 protocol message packet generally embeds the IP address and port number in a specific section, rather than placing it in the IP packet header. Therefore, when the H.323 data packet passes through the NAT device, the IP address and port number will have may not point to the correct place
[0006] To sum up, on the one hand, H.323 multimedia communication services can penetrate firewalls and NAT devices without reducing the security of the network system, which is a problem that must be solved for the widespread application of multimedia; The working principle of the address converter is different, and the security mechanism and the security level achieved are also different. At present, they cannot support the multimedia communication based on the H.323 protocol well.

Embodiment Construction

[0032] like figure 1 As shown, the IP multimedia communication service processing system of the present invention is used to transmit signaling and media streams based on the H.323 protocol through a firewall or a network address translation device, wherein:

[0033] The H.323 terminal 10 is set in the private network and is a terminal device for receiving and sending H.323 calls.

[0034] The network detection client 20 is set in the private network, receives and sends network environment detection messages, and is used in cooperation with the network detection server 30 .

[0035] The network detection server 30 is set in the public network, receives and sends network environment detection messages, and is used in conjunction with the network detection client 20 .

[0036] The traversal client 40 is set in the private network, and establishes a data channel with the traversal server 60 according to the result of network detection; receives signaling and media streams from t...

Abstract

This invention discloses one IP multi-media communication business process system and its method to send the signals and media flow pass firewall or NAT network, wherein, the IP multi-media communication business process system comprises the following parts: H. 323 terminal, network address conversion or firewall, H. 323 network gate, network test customer end, network test servo, pass customer end and pass servo.

Description

technical field [0001] The invention relates to H.323 multimedia communication technology, in particular to a system and method for H.323 signaling and media flow passing through firewall and network address translation (NAT). Background technique [0002] With the rapid development of Internet, VoIP (Voice Call via Internet or IP Network) technology has attracted many users with its low price and good call quality. Using Internet-based Internet telephony (that is, using IP calls) can greatly save long-distance charges. Taking international long-distance calls as an example, the cost can save up to 95% compared with traditional international long-distance charges. Video telephony is a new communication mode developed based on VOIP technology. On the basis of voice communication, it also provides interactive transmission of video images to realize real visual communication. The H.323 protocol family is one of the main protocols that can maturely realize multimedia communicat...
