Abstract
The gateway is composed of regular hardware voice plate card/voice modem, network card, dedicated software, and computer platform (PC or industrial controller etc. and operation system for computer). Voice plate card / voice modem is in use for processing, receiving and transferring signaling and signal of telephone network. The network card is in use for transferring signaling in IP network and signal. The dedicated software realizes communication protocol, transport protocols, channel control and voice encoding etc. Running on computer platform, the said three parts implement function of media gateway between telephone network and IP network so as to reach target of media communication between IP network and telephone network.
Description
Technical field
The present invention relates to the implementation method of media gateway, particularly relate to the gateway implementation method of communication between the voice transmission technology (VoIP) of internet protocol-based and PSTN network
Background technology
Existing media gateway all is embedded, the can minor, therefore just produces following problem:
1, port, the slot back of dispatching from the factory just can not be changed, so capacity also immobilized, and this has just brought trouble, dilatation inconvenience to the capacity requirement of increase day by day;
2, embedded software is solidificated in the hardware when producing, bug and software originally are twin sisters, problem can exist, agreement, standard, method for designing are all being improved, upgrading is just very difficult behind the new edition software publishing, even some can be upgraded, also need the professional just can carry out, be very much inconvenient;
3, new function, new application such as IVR, telephonograph, monitoring all are difficult to merge;
Summary of the invention
The objective of the invention is to be difficult for upgrading, new function and the implementation method that a kind of software gateway that is difficult to merge and provides is provided in order to solve media gateway capacity limit, dilatation inconvenience, software.Consider present media gateway problems, we adopt software and hardware to separate and the technology that combines, and adopt hardware commonly used to finish the processing of physical layer signal, and software is realized core protocol and application.
The technical solution used in the present invention has:
1, computer (PC, industrial computer etc.) and run on the basic platform (computer platform) that operating system (Windows, Linux etc.) on the computer constitutes gateway provides other hardware interface and computing ability;
2, voice plate card/voice Modem links to each other with the hardware interface of computer platform, and telephony port links to each other with telephone network, is used for accepting and transmission pstn signaling and signal;
3, network interface card links to each other with the computer platform hardware interface, and network interface is connected with IP network, is used for accepting and transmission voip signaling and signal;
4, realize VoIP agreement etc. with software, software control voice plate card/voice Modem is accepted the pstn signaling signal, and the control network interface card is accepted the IP data, explains exchange VoIP and pstn signaling signal, gives the other side then respectively and transmits.
Description of drawings
Fig. 1 is a media gateway configuration diagram of the present invention
Specific embodiments
(equipment function and to handle thing similar in the present invention, below described only be example) with the voice plate card because voice plate card, voice Modem are expected someone's call
Be illustrated in figure 1 as media gateway Organization Chart of the present invention, computer platform is computer electronic products such as common PC/industrial computer and runs on operating system Windows, Linux on this computer or other, we install electronic equipments such as network interface card, voice plate card or voice Modem on this computer platform simultaneously, and these products all are common, software is only the core place of native system, we develop a cover software, it has realized the necessary agreement of VoIP communication and gateway communication, passage control or the like function, finishes following thing:
1, under the control of software, voice plate card is monitored the call signal of telephone network, and software determines whether initiating voip call and sets up voip conversation by network interface card according to the signal that captures when calling out generation, the control session;
2, software receives packet by network interface card from IP network, extracts the required data of called telephone network users, and whether decision makes a call, selects sound card telephone channel and telephone net user to set up session and control session;
3, under the control of software, telephone speech signal is converted to data-signal by voice plate card, and software is sent to IP network with this data-signal coding back by network interface card, makes voice arrive the VoIP end subscriber;
4, software is by the VoP of network interface card reception from IP network, and decoding arrives telephone net user at last after voice plate card is converted into analog voice signal.
Claims (1)
1, a kind of implementation method of media gateway, the media gateway that adopts this method to realize, purpose is to realize medium (as the voice) communication between telephone network (PSTN) and IP network, 1), computer platform (PC/industrial computer etc. and run on operating system (as Windows, Linux) on the computer) is its basic platform as telephonic communication, it is characterized in that:; 2), voice plate card/voice Modem links to each other with computer platform, its telephony interface is used to connect PSTN, transmits and receives various signalings of PSTN and signal; 3), network interface card (network adapter) links to each other with computer platform, its network interface connects IP network, is used to transmit and receive the signaling and the signal of VoIP communication; 4), the running software of having realized the VoIP agreement on computer platform, control voice plate card/voice Modem and communication, passage control and the VoIP of network interface card exchange with pstn signaling, signal interpretation, the realization IP network is communicated by letter with telephone network.
