System and method for convergence access of intelligent terminal

Abstract

The invention discloses an IP voice intelligent terminal accessing system and method including network communication interface, data base model, register, certification model, protocol analyzing and processing model, voice and message processing model; the intelligent terminal is connected to the access system through network communication interface; the register and certification models are connected to the network communication interface through protocol analyzing and processing model, the register and certification model, protocol analyzing and processing model, and the voice and message processing mode are connected to data base, the protocol processing model is connected to the voice and message processing model. The intelligent terminal integrating system in the invention does not communicate with MGC directly, realizes the separation of operation core network and access network. The real MGC is transparent to the intelligent terminal.

Description

technical field [0001] The invention relates to an IP voice intelligent terminal convergence access system and an access method. Background technique [0002] IP voice access devices include MGCP (Media Gateway Control Protocol, Media Gateway Control Protocol) terminals, SIP (Session Initiation Protocol, Session Initiation Protocol) phones, H.323 (H.323 is one of the important standards of ITU multimedia communication series standards , the aspects concerned are video conferencing) terminals, H.248 terminals, etc. are collectively referred to as intelligent terminals (Intelligence Terminal IT). [0003] Although the traditional Public Switched Telephone Network (PSTN) based on Time Division Multiplexer TDM can provide 64kbit / s (based on 2M link) service, the service and control are all completed by the switch. PSTN can guarantee excellent voice quality, but the provision of new services is relatively complicated and requires a long response cycle, which makes operators feel...

AI Technical Summary

Problems solved by technology

[0011] 1. Authentication and authorization of access equipment, the current VoIP access lacks the necessary identity authentication and authorization for IP voice access equipment;

[0012] 2. Security issues of core network equipment. Since IP voice access equipment directly communicates with core network equipment such as soft switches, IP voice access equipment is distributed in a complex network, which is likely to cause security issues, and once a security issue occurs, it may cause The whole network fails;

[0013] 3. Communication security issues. Signaling and voice are transmitted in clear text, and the network nodes passing through are complex and loose, which makes signaling and voice easy to be intercepted and tampered with;

[0014] 4. Signaling and voice cannot penetrate NAT and firewall devices. When there are NAT and firewall devices between the IP voice access device and MGC, the current VoIP solution cannot communicate normally;

[0015] 5. The software upgrade of a large number of access devices. Since VoIP is in its infancy, many technologies and functions are still in the exploratory stage. In addition, the software itself needs to ...
