Description
Technical field
The present invention relates to the multi-media communication technical field, particularly a kind of network-building method of video communication network and DHCP (DHCP, Dynamic Host Configuration Protocol) server.
Background technology
Popularizing and, become a kind of common exchange way gradually along with the internet based on the video conference of video communication network based on the continuous development of TCP/IP network technology.Video communication network is made up of video terminal, registrar, transmission channel and multipoint control unit (MCU) etc. usually.Each video terminal is gathered local picture and voice data, is transferred to MCU through after the encoding compression; MCU reintegrates and allocates above-mentioned data, according to conference creation person's demand the multichannel audio-video frequency data flow is integrated into an audio/video flow, is issued to each video terminal; Each video terminal decoding playback, thus make each video terminal obtain unified image and sound.Video terminal can carry out video communication with other video terminal as a desktop intelligent terminal.Usually, video terminal needs to register to a registrar earlier, in order to the sign-on ID of announcing this video terminal and the corresponding relation of IP address.Can carry out call conversation according to IP address or corresponding sign-on ID between the video terminal.Above-mentioned registrar is called the gatekeeper in the video conferencing system based on the H.323 standard of ITU-T (GK Gatekeeper), is called registration (Register) server in the SIP system.
Figure 1 shows that as shown in Figure 1, this network comprises video terminal A and B, Dynamic Host Configuration Protocol server, registrar GK and multipoint control unit MCU based on the structural representation of the video communication network of standard H.323.This meeting is given with video terminal IP address or with the formal definition of this corresponding sign-on ID in IP address in each meeting-place (being video terminal) that MCU sets up a video conference to be needed to participate in this meeting in advance.In the time of the needs holding video conference, thereby MCU calls out each video terminal to holding multi-point video conference.In the prior art, each video terminal of participating in video conference is formed a video communication network, normally carry out in accordance with the following methods: dispose the registrar address of this video terminal and the information such as sign-on ID of this video terminal in advance at the video terminal place, and each video terminal of participating in video conference in the definition of MCU place; Each video terminal carries the sign-on ID of self and registers to registrar GK, thereby the binding relationship of its own IP address and sign-on ID is announced to GK, so that other video terminals can be called out this video terminal by this sign-on ID after starting; MCU calls out each video terminal of participating in this video conference, and each video terminal is formed a video communication network, is used to set up video conference.Because on behalf of a meeting-place, a common video terminal participate in video conference, therefore can also be in advance in information such as video terminal place configuration meeting place name and address lists, video terminal is called out other video terminals according to above-mentioned address list, thereby need not communicating by letter of point-to-point that MCU participates in other video terminals.
From foregoing description as can be seen, set up a video communication network in the prior art and set up video conference, the configuration effort that need repeat in a large number at video terminal and MCU place, thereby the workload that administers and maintains is bigger, and the situation of configuration error takes place easily; And because each video terminal of conference participation is distributed in different physical locations, often can only be by the own configuring video terminal of meeting participant, obviously, this requires too high for common meeting participant.
