Problems solved by technology
This is because the service is different from an audio call, and images are too informative
Therefore, the current mobile communication system not only has limited wireless resources, but also has far less bandwidth than wired communication.
[0007] At the same time, using the current mobile communication system to accept services similar to video calls has the problem of paying astronomical fees. However, when using non-real-time services such as multimedia information services, it is different from video calls and cannot be realized in real-time. Disadvantages of talking on the phone while transmitting image information in real time

Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0021] Accompanying drawing 2 is the flowchart corresponding to the real-time video call service method of the mobile communication terminal of the present invention, the user who needs to carry out the still image video call first utilizes the menu operation on the mobile communication terminal to set the still image video call.
[0022] The difference between the still image video call menu and the existing video call menu is that the video channel will not be occupied all the time, but only when the still image needs to be transmitted, the video channel will be opened for transmission, and will be closed after the transmission video channel, and each time the still image transfer button is clicked, the steps will be repeated.
[0023] Then, as mentioned above, after completing the setting of the still image video call, input the other party...

Video talking method of mobile communication terminal comprises: step 1, setting still image call through menu; step 2, inputting partner phone code and clicking video talking key to perform talking invitation of still image after accomplishing the above step1; step 3, openning voice channel of realtime transmission protocol to perform voice frequency telephony if the partner responses through video talking invitation; step 4, catching video imported by camera and compressing by still image compression algorithm when the user clicks still image transmission key in the said voice frequency telephony; step 5, openning voice channel of realtime transmission protocol and transferring the compressed still image to mobile communication terminal of partner. In mobile communication terminal for performing video talking, the required still image is transferred in real-time in conversation, thus the video frequency call charge is reduced and the user convenience is advanced.
Description
technical field [0001] The present invention relates to the field of mobile communication, in particular to a mobile communication terminal, specifically, a video call method for a mobile communication terminal. Background technique [0002] Usually, existing mobile communication terminals are mainly used for audio calls, but with the development of technology, a system that can realize video calls has emerged. At the same time, technologies related to mobile communication have also been developed rapidly, so video calls can now be realized . In addition, due to users' demand for new services of mobile communication terminals, everyone's attention to video calls has also increased. However, there are still many problems in the environment of the current mobile communication system. For example, when implementing video calls on the CDMA2001-1x or EVDO network, the communication speed is slow and the corresponding cost is also high. [0003] Similar to the uninterrupted real...
