Embodiment Construction

[0022] In order not to interrupt the original call when using the busy prompt function, connect the voice channel of the opposite end and the voice channel of the busy prompt tone to the voice channel synthesis module, and the voice channel synthesis module performs the voice channel of the opposite end and the voice channel of the busy prompt voice Audio mixing processing, which synthesizes a voice channel, and then plays the synthesized voice channel to the local voice channel, so that the user can not only hear the voice of the peer end, but also hear the busy prompt tone.

[0023] A specific embodiment of the present invention utilizes the software system already possessed by the main control module of the digital program-controlled exchange, and utilizes the existing functions of the exchange such as busy prompt service control processing and conference resource management, and then adds appropriate software processing to form a three-party The system that plays the busy p...

Abstract

The invention discloses a system for playing a busy tone during the digital program-control exchange, which is used to display the busy tone without interrupting the communication between a user at a local terminal and a user at an opposite terminal. The system comprises a busy tone hint processing module for triggering a busy tone hinting service. The system further comprises a speech path syntheses module for synthesizing a speech path from the opposite terminal speech path and the busy tone hinting path. The busy tone hint processing module is also used to join the opposite terminal speech path and the busy tone hinting path to the speech path syntheses module when the busy tone hinting service is triggered and play the speech path synthesized by the speech path syntheses module to the local terminal speech path. The invention can ensure the user's communication not to be interrupted when displaying the busy tone.

Description

technical field [0001] The invention relates to the technical field of digital program-controlled switching in communication technology, in particular to a system and method for playing a busy prompt tone in digital program-controlled switching. Background technique [0002] The busy notification service is a function that reminds the user that there is a new call if a new call comes in when the user is busy. At present, for the prompt tone of the busy prompt service provided by the digital program-controlled exchange, the prompt tone is directly connected to the user's voice channel, and the prompt tone is played to the user who registers the service. [0003] The shortcoming of this method of playing the prompt tone is that, in the process of playing the prompt tone, the calling channel of the original user needs to be temporarily cut off, thus affecting the original conversation, especially if the user has a lot of calls when busy It will be interrupted frequently, affec...
