Embodiment Construction

[0041] The embodiment of the present invention provides an automatic fallback solution from a video call to a voice call in a 3G network through a mobile phone, so as to solve the problem that the user wants to use a voice call in some scenarios, but manually chooses to use a video call for connection by mistake , and the automatic fallback function avoids the occurrence of such human errors. At the same time, through the automatic Vioce answering function and any key Voice answering function, it greatly facilitates the user's operation of answering calls.

[0042] Wrong manual selection to use video call to continue the situation includes the user's surrounding environment is not convenient for video video, the power of the user's mobile phone is not enough to continue the video and manual selection to continue the video may lead to the sudden end of the call, the user's personal misoperation leads to a video call, etc. , and some other unexpected situations lead to the wrong...

Abstract

The embodiment of the invention discloses a method, a device and a system which are used for leading video call to be fallen back to voice call. The method of the invention comprises the steps as follows: whether current video call meets a condition by which the pre-arranged video call is fallen back to the voice call is judged; if so, the indicating information in which the video call is fallen back to the voice call is sent to network side equipment and the current video call is received in the form of voice call. The technical proposal of the invention realizes the automatic balling-back of the current video call to the voice call when the terminal meets the condition by which the pre-arranged video call is fallen back to the voice call, thus achieving the effects of facilitating the user to receive the phone and reducing the error call caused by the misoperation.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method, device and system for video call fallback to voice call. Background technique [0002] 3G (The Third Generation, third-generation mobile communication) is a network bearer technology that can provide all voice and data services of a 2G (The second Generation, second-generation mobile communication) network. Typical services that can be provided in the 3G network include video phone or video phone (Video Phone) service, PoC (Push to talk over Cellular, Push to Talk) service, IM (Instant Message, instant messaging) service, and streaming service. Among them, Video (video) call is a 3G-specific service, and 3G MSC (Mobile Service Center, Mobile Service Switching Center) can support this service, and MSC can also realize the multi-party visual call function of 3 to 5 parties. [0003] On a 3G network, calling user A initiates a video video call to B, and user...
