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 implementing the present invention is given, including 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, perform step 103 to perform other processing; otherwise, perform 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 the corresponding voice channel is established, perform step 105 for other processing, otherwise perform step 106 to start timing Device.

[0020] In order to ensure that the user can successfully receive the prompt message, if the call rejection is sent to the terminal together with the prompt message, the terminal will not process the prompt message before the release is completed. Therefore, there must be a delay for the user to complete the release. C...

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 present invention relates to the field of communication, in particular to a method for notifying a user when a call fails. Background technique [0002] Voice Channel (Voice Channel) is a channel that transmits voice data between the mobile station and the network side. When a mobile user makes a call, if a call failure occurs before the voice channel is established between the mobile station and the network side (for example, voice channel assignment failure, no ground circuit available, etc.), at this time, because there is no voice channel, If the call fails, an error tone cannot be played to the caller, and the network side will disconnect the call directly. In the above situation, the caller will not get any call failure notification. For the mobile station, the terminal will go back to the idle state after dialing the number for a while. The user is not clear about what went wrong, which reduces The friendliness of the system. Summary of the inve...
