For example, just wanting to show the own article of being purchased, wanting to hear the other side's suggestion simultaneously for one to another user in strange land the user of market shopping.If the user utilizes video calling, can be real-time transmitted to the other side to the image of article, can also converse with the other side simultaneously; , if the user utilizes MMS (Multimedia Message Service) (MMS),,, therefore has the shortcoming that needs to wait for certain hour so can only after confirming to receive information, just can converse because it is to transmit data with the mail form.
Accompanying drawing 1 is the flow chart corresponding to the real-time video call method of servicing of existing communication terminal.In order to carry out video calling, the user by input the other side telephone number and click the video calling dedicated button, can connect with the other side.If when the other side has response, utilize RTP (Real-Time TransportProtocol-RTP), transmit animation and voice, begin to converse.Certainly, also be included in the function of selecting one to transmit in described two kinds of information during video calling.
On communication terminal, realize aforesaid video calling service, need a large amount of Radio Resources (channel width).This is because this service is different with voice-frequency telephony, and information content of image is excessive causes.So, present mobile communcations system, not only its Radio Resource is restricted, and compares with wire communication, and its bandwidth is nowhere near.
Simultaneously, utilize present mobile communcations system to accept to be similar to the service of video calling, exist the problem that needs expense as the payment astronomical figure, but during as if this class non real-time service of usefulness MMS (Multimedia Message Service), they are different with video calling, have the drawback of conversing when can not be implemented in the real-time Transmission image information.
Summary of the invention
In order to solve the described problem that prior art exists in actual mechanical process, the invention provides the video call method of communication terminal, its purpose is: can carry out on the mobile communication terminal machine of video calling, only transmit necessary rest image in the conversation in real time, therefore the video calling expense can be reduced, user convenience can also be improved simultaneously.
In order to realize aforesaid purpose, the present invention is made up of following step, it is characterized in that:
Step 1 by menu, is set the rest image conversation;
Step 2, finish described step after, input the other side telephone number, and click the video calling key carries out the rest image conversation and invites;
Step 3 is invited by described video calling, and if the other side is when having response, only open RTP (Real-Time Transport Protocol, voice-grade channel RTP) is finished voice-frequency telephony;
Step 4 in described voice-frequency telephony, when clicking the Still Image Transmission key by the user, is caught the image by the camera input, and is compressed with the rest image compression algorithm;
Step 5 is opened the video channel of RTP, described compression back rest image is sent to the other side's communication terminal.
The difference of described still video transmission conversation menu and existing video calling menu is: can not take video channel always, but only when needs transmit rest image, just can open video channel transmits, and after transmitting end, video channel is closed, and when clicking the rest image transfer key, all can carry out described step repeatedly at every turn.
After described recipient's communication terminal recovers compressing image, output in the LCDs picture, and this image is stayed on the picture of LCDs always, up to receiving next rest image, can also press storage key in addition, the image of receiving is stored in the internal storage of communication terminal.
As the explanation of carrying out above, video call method corresponding to communication terminal of the present invention, has following effect: can carry out on the communication terminal of video calling, necessary rest image during only real-time Transmission is conversed, therefore the video calling expense can be reduced, user convenience can also be improved simultaneously.
