Method for processing videophone calling failure based on mobile communication network

Abstract

The invention relates to a method for processing the calling failure of video telephone, based on mobile communication network, which comprises: when the video telephone calling generated by the calling terminal fails, the mobile communication network, based on the reason, feeds back the calling failure message to the calling terminal, while said message contains the calling failure reason value and the detach command; said calling terminal receives the calling failure message, based on the reason value to inquire and extract the calling failure prompt message data, to display the calling failure prompt message locally. The invention presets calling failure prompt message at the video calling terminal, to send the calling failure command at the network, to make the video calling terminal obtain failure reason on time, to utilize the system resource fully.

Description

technical field [0001] The invention relates to a method for processing videophone call failure based on a mobile communication network, in particular, in a mobile communication system, when the caller sends a videophone call request to the called party but fails to link successfully, the The method for the calling party to play the call failure prompt voice. Background technique [0002] With the putting into use of the mobile communication network (such as 3G network) supporting the videophone, mobile users can conduct mutual video calls through the video mobile terminal. [0003] In the above-mentioned mobile communication network supporting videophone, the signal transmission between the two parties is different from the data stream transmission method in the previous 2G network, but uses the method of sending data packets to realize massive video and audio data transmission. The visual call information of the mobile switches of the called parties and the entire communi...

Problems solved by technology

[0005] Since the information transmission method of the mobile communication network supporting videophone is different from that of the 2G network, when a calling terminal in the network initiates a call request to another called terminal, if the called terminal is in an unavailable state, according to the current international norms, when the call fails, the network side does not perform any announcement process, even if the network side plays the call prompt tone, but because the call prompt tone is not a data package that adopts data encapsulation and compression processing, therefore, The calling user cannot get any prompt information about the call failure, and has no way of knowing the reason for the call failure. At the same time, the calling user waits when he does not know whether the call fails, which also causes a waste of system resources.
