Problems solved by technology

When a mobile user makes a calling call, if a call failure occurs before the voice channel is established between the mobile station and the network side (for example, the voice channel assignment fails, there is no available ground circuit, etc.), because there is no voice channel at this time, for If the call fails, the error prompt tone cannot be played to the caller, and the network side will directly disconnect the call
And in the above case, the calling party just can't get any prompt of call failure. For the mobile station, the terminal returns to the idle state directly after dialing the number for a while. System friendliness

Embodiment Construction

[0016] Such as figure 1 as shown, figure 1 A flow chart of the method for realizing the present invention is provided, comprising the following steps:

[0017] Step 101: The mobile user initiates a call request.

[0018] Step 102: Analyze whether the call fails, if the call is successful, execute step 103 and perform other processing, otherwise execute step 104.

[0019] Step 104: The mobile switching center MSC rejects the call, and analyzes whether a voice channel is established between the network side and the mobile user, if a corresponding voice channel is established, then execute step 105, and perform other processing, otherwise execute step 106, start a timing device.

[0020] In order to ensure that the user can successfully receive the prompt information, if the call rejection is sent to the terminal together with the prompt information, the terminal will not process the prompt information before the release is completed, so it must be delayed until the user relea...

Abstract

The invention relates to a method for informing user about the call failure. Wherein, the mobile user sends call request, before building the voice signal channel, judge if there is call failure; if there is, starting the timer; in the preset time of timer, if receiving the message about the mobile user recall, the timer stops, execute the front step; or else, the MSC sends error prompt to the user. With said invention, when the mobile user calls, and there is no voice signal channel between the mobile station and the network, the network can use word, voice, word-voice, or message to give error prompt to the user.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for notifying a user when a call fails. Background technique [0002] Voice Channel (Voice Channel) is a channel for transmitting voice data between the mobile station and the network side. When a mobile user makes a calling call, if a call failure occurs before the voice channel is established between the mobile station and the network side (for example, the voice channel assignment fails, there is no available ground circuit, etc.), because there is no voice channel at this time, for If the call fails, the error prompt tone cannot be played to the caller, and the network side will directly disconnect the connection. And in the above case, the caller just can't get any prompt of call failure. For the mobile station, the terminal returns to the idle state directly after dialing the number for a while. System friendliness. Contents of the invention [0003] In view of this,...
