Problems solved by technology

[0004] Currently used voice codecs are usually implemented using relatively expensive high-speed semiconductor devices, such as DSP (Digital Signal Processor), so the cost of realizing the playback function of prompt tone and signal tone is very high
Using the existing technology to realize 1000-channel prompt tone / signal tone playback equipment requires the use of 1000-channel voice codec and corresponding packet processing system. The cost of the voice codec is $10 / channel, and the cost of the packet processing system is $100, so the traditional implementation costs $10100
Moreover, when the existing technology is used to play prompt tones / signal tones to multiple endpoints, especially when the prompt tones / signal tones of multiple endpoints are different, it is usually necessary to allocate multiple voice codec channels, resource allocation management is relatively cumbersome, and greatly increased implementation complexity

Embodiment Construction

[0029] The specific embodiment of the method for realizing the function of playing prompt tone and signal tone in the communication network of the present invention is described as follows in conjunction with the accompanying drawings:

[0030] When user information needs to be played to users in mobile and fixed packet voice networks, refer to figure 1 , compress the prompt tone and signal tone information carried by the file to be played according to different speech coding types or different speech coding rates into corresponding speech frame files of prompt tone and signal tone; the speech coding frame length of the speech frame file Can be the same or different, see step 1.

[0031] Then, according to the same time interval, the voice frame files of all prompt tones and signal tones obtained in step 1 are segmented, see step 2; the time interval between the voice frame file segments can be set to the speech coding frame length An integral multiple of the least common mul...

Abstract

This invention relates to a method for realizing functions of playing prompt and signal voices including compacting the needed playing prompt voice and signal voice information according to differentphonetic coding kinds of different rates to generate related phonetic frame files, then segmenting all the phonetic frame files in terms of same time intervals and identifying each assigned segment sequential number, and therefore, when the prompt and signal voices are played, the switching can be done between different phonetic frame files to ensure the playing continuity. This invention omits the phonetic coder in the present technology and need not the sources of assigned phonetic coders.

Description

technical field [0001] The invention relates to a method for playing prompt tone and signal tone mainly applied in mobile and fixed communication networks. Background technique [0002] In mobile communication and fixed communication network telephone services, operators often need to provide users with signal tone and prompt tone playing services; moreover, with the development of intelligent services, they will also need to provide more complex intelligent prompt tone playback functions. At present, in mobile and fixed packet voice networks, voice signals are transmitted and exchanged in the form of packets after voice coding. [0003] In the mobile and fixed packet voice telephone services, you can choose to use multiple voice coding formats, that is, choose different coding types, and there may be multiple rates for the same type of voice coding, for example, fixed packet voice services Usually support G.711, G.729, G.723.1 voice coding, G.723.1 voice coding includes tw...
