Description
Technical field
The present invention relates to video conference call field more particularly to a kind of bases applied on mobile phone terminal and conference terminal
Video phone conference system in VoLTE and the method using system progress video conference call.Following mobile phone terminal and
Conference terminal is referred to as terminal.
Background technique
With the continuous development of society, requirement of the various circles of society for communication is also higher and higher, especially smart phone
Appearance so that visual telephone, video conference call become a kind of more more and more universal communication mode.How by existing logical
Letter transmission channel and existing computer network are that society provides that easy to operate, cost is relatively low, quality is guaranteed and leads to existing
The video phone conference system being applied in terminal that letter system organically combines, becomes the project that must be solved.
Current video phone conference system is many kinds of, but the video data in most of video phone conference systems and
Voice signal is to realize in a network.What it is due to video phone conference system transmission is multi-medium data, to reach high quality
Data transmission need Bandwidth guaranteed, in the case where current operator still not can guarantee bandwidth, easily cause the disconnected of voice
Discontinuously continuous and image Caton.In addition, terminal can temporarily break when making a phone call under the existing communication system architecture of operator
Net synchronous in call can not receive and dispatch vision signal, can not solve to converse simultaneously particularly across the terminal of operator and video passes
Defeated problem.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide one kind to can be realized at the terminal
Call simultaneously and video data transmission, structure be simple, the guaranteed video conference call system based on VoLTE function of voice quality
System and the method for carrying out video conference call using the system.
Technical solution used by video phone conference system of the present invention based on VoLTE is: the system includes extremely
Few two terminals, video management server and MCU,

The VoLTE function and Public Switched Telephone Network of terminal have fully ensured that the quality of voice, will not generate the interrupted phenomenon of voice,
It admirably ensure that video speech quality, and framework is simple, it is at low cost.
Further, the video management server includes but is not limited to DDNS server and PS server, the DDNS
Server is connect with the terminal and the PS server respectively by internet, at least two ends that record management is attended a meeting
End carries out address resolution to the terminal, receives the Conference Calling information and video of the terminal requested from initiating conference
Information, and Conference Calling is forwarded to each terminal attended a meeting；The PS server by internet respectively with the terminal
And the DDNS server connection, the vision signal from each terminal attended a meeting is received, and be transmitted in need
The terminal attended a meeting.
Above scheme is therein as it can be seen that video management server includes but is not limited to DDNS server and PS server
DDNS server is connect with the terminal and the PS server respectively by internet, at least two institutes that record management is attended a meeting
State terminal, address resolution carried out to the terminal, receive the Conference Calling information of terminal request from initiating conference with
Video information, and Conference Calling is forwarded to each terminal attended a meeting；And PS server then pass through internet respectively with it is described
Terminal and DDNS server connection, receive the vision signal from each terminal attended a meeting, and being transmitted to need to
The terminal attended a meeting wanted；In brief, DDNS server is responsible for data processing, and PS server is responsible for data transmission and is turned
Hair, function is separated into and is each responsible for by two servers, data-handling efficiency is improved, also avoid error probability, more after
Continuous maintenance is provided convenience.
Further, the terminal includes mobile phone terminal and conference terminal with VoLTE function.It can be seen that having
The mobile phone terminal and conference terminal of VoLTE function are able to achieve video conference call of the present invention, to reduce equipment
It is required that.
Using above system carry out video-conference phone method the following steps are included:
(1) terminal through internet of initiating conference initiates video conference request to the video management server；
(2) after the video management server verifying initiating terminal information, each terminal attended a meeting by internet notification,
And record the relevant information of attend a meeting terminal and initiating terminal；
(3) terminal that each of has notice establishes language by Public Switched Telephone Network and the MCU using VoLTE function
Sound connection, and current video data is sent to the video management server by internet；
(4) MCU receives the voice from the terminal attended a meeting, and carries out stereo process to voice, and by treated
Voice sends the terminal attended a meeting back to；
(5) video management server receives the video data that the terminal of each of attending a meeting transmits by internet, and will
Video data is sent to the terminal in need attended a meeting；
(6) hanging up terminal exits meeting.
As it can be seen that video management server of the present invention formerly records the information of each terminal of meeting, receiving comes above scheme
From the request for conference of the terminal of initiating conference, after being verified to initiating conference terminal, before notifying each terminal attended a meeting
Video conference call is participated in, notified each terminal built using VoLTE function by Public Switched Telephone Network and MCU
Vertical voice connection, and send itself current video and arrive Video Manager, MCU to the voice progress stereo process received, and
Treated voice signal by VoLTE function is sent back into each terminal of attending a meeting, to utilize the functional characteristics guarantee of VoLTE
The continuity of voice, at the same by video management server by video be transmitted to it is in need attend a meeting in terminal, realize video
Videoconference, to realize that the voice signal and video data that will have mobile phone terminal, conference terminal of VoLTE function etc. are realized
Simultaneous transmission, VoLTE function therein have fully ensured that the quality of voice, will not generate voice disconnection phenomenon, admirably guarantee
Video speech quality, and method is simple, it is easy to operate.
