Description
Technical field
The present invention relates to communication fields, are specifically a kind of method for realizing video communication PTT functions.
Background technology
China has been proposed PTT mobile phones on the market at present, and the function of PTT mobile phones is using packet switching network, and one presses
It can converse, " one-to-one " or " one-to-many " call can be quickly carried out in whole network, without call establishment,
Just as using intercommunication message register.It is real as long as clicking the corresponding button i.e. PTT keys of mobile phone after mobile phone opens PTT service
The call of " one-to-one " or " one-to-many " is now realized with selected group.
PTT functions are also common technology in intercom, the occasions such as police or army are widely used in, using packet switch
Mode realizes the transmission of voice or voice short message, but intercom can only transmit voice after all, and the information content of transmission is very little, far
The information content that video and image transfer is can not show a candle to, current PTT mobile phones can only also hear the sound of partner when being conversed
Sound, but cannot see that the video image in the region where partner or other side, and user can not judge the ring where partner
The inconvenience used on sense organ is brought in border region to user.
The content of the invention
It is an object of the invention to provide it is a kind of it is at low cost, it is easy to use realize video communication PTT functions method, with
Solve the problems mentioned above in the background art.
To achieve the above object, the present invention provides following technical solution：
A kind of method for realizing video communication PTT functions, is as follows：
（1）After terminal device start, user's registration is carried out under the instruction of user, terminal device sends login request message
To server, Subscriber Number and the binding relationship of IP address are registered in server side, authenticating user identification is carried out, and obtains correlation
Information；
（2）After authenticating user identification success, configuration information of the server side for the user is allocated to terminal by server
Equipment；
（3）Terminal device periodically sends heartbeat data packets to keep online to central server, the note of performance period
Volume function, server determine the audio and video data streams sent according to the online situation of the terminal device detected, and IP variations is avoided to lead
The abnormal conditions of cause；
（4）After user completes to register and obtains configuration information, terminal device initiates the base of calling group system to server
This function, terminal device open transmission audio/video flow udp port after initiating call request；
（5）Server initiates call request after call request is received, for each called terminal device；
（6）Called terminal device receives call request, is opened after call setup and receives audio/video flow udp port stand by tone
Video flowing, server carry out confirming call.
As further embodiment of the present invention：The multicast group that the configuration information includes the default group of user, user adds in
With the other configurations of current multicast group.
As further scheme of the invention：The terminal device is equipped with camera, microphone and buffer area.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention realizes the extension to traditional PTT functions, and video PTT is integrated in video conferencing system, passes through words
The mode that power is transferred realizes video communication PTT functions, when carrying out PTT intercommunications, can not only transmit voice, moreover it is possible to carry out video
Transmission, increase the information content of transmission, it is at low cost, be user-friendly.
Description of the drawings
Fig. 1 is the flow chart of user's registration in the present invention.
Fig. 2 is the flow chart that individual calling two-way call is carried out in the present invention.
Fig. 3 is the flow chart that the multidirectional call of individual calling is carried out in the present invention.
Specific embodiment
The technical solution of this patent is described in more detail With reference to embodiment.
- 3 are please referred to Fig.1, a kind of method for realizing video communication PTT functions is as follows：
（1）After terminal device start, user's registration is carried out under the instruction of user, terminal device sends login request message
To server, Subscriber Number and the binding relationship of IP address are registered in server side, authenticating user identification is carried out, and obtains correlation
Information；
（2）After authenticating user identification success, configuration information of the server side for the user is allocated to terminal by server
Equipment, configuration information include the other configurations of the default group of user, the multicast group that user adds in and current multicast group；
（3）Terminal device periodically sends heartbeat data packets to keep online to central server, the note of performance period
Volume function, server determine the audio and video data streams sent according to the online situation of the terminal device detected, and IP variations is avoided to lead
The abnormal conditions of cause；
（4）After user completes to register and obtains configuration information, terminal device initiates the base of calling group system to server
This function, terminal device open transmission audio/video flow udp port after initiating call request；
（5）Server initiates call request after call request is received, for each called terminal device；
（6）Called terminal device receives call request, is opened after call setup and receives audio/video flow udp port stand by tone
Using Session Initiation Protocol or H.323 video flowing, server carries out confirming call, and in calling procedure, agreement is exhaled in call setup
It is the information carrying capacity of ability and port negotiation.
The terminal device is equipped with camera, microphone and buffer area, and server is by receiving camera and microphone
Data, and the audio/video flow for being encoded into H.264 form is compressed it, it is sent by IP network and interactive, when light is bad, adopted
Solve the problems, such as that camera imaging is not known with the camera sensing device and light compensating lamp of low-light (level)；The buffer area caches several sounds
Video data can be good at ensureing the stability that terminal device shows video in certain network delay jitter range.
Video PTT is integrated in video conferencing system by the present invention, and video communication PTT is realized by way of right of speech transfer
Function, PTT keys are equivalent to the speech application key in video conferencing system, video conferencing system according to the speech received apply when
Between, earliest application terminal device is selected to authorize its competence of speech, while the speech application of other-end equipment is emptied, it obtains
The terminal device of competence of speech, which can just send audio, video data and pass through server broadcast, gives other-end equipment, avoids simultaneously
There are two or more than two terminal devices send audio and video situation occur.
The present invention realizes the extension to traditional PTT functions, when carrying out PTT intercommunications, can not only transmit voice, moreover it is possible into
The transmission of row video increases the information content of transmission, at low cost, is user-friendly.
The better embodiment of this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
Formula, can also be on the premise of this patent objective not be departed from the knowledge that one skilled in the relevant art possesses
Various changes can be made.
