Embodiment Construction

[0054] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0055] Based on the above problems, the present invention provides a call playback control method.

[0056] refer to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the call announcement control method of the present invention.

[0057] In this embodiment, the call playback control method includes:

[0058] Step S10, the media gateway receives the call playback request carrying the sound packet information;

[0059] In this embodiment, the media gateway receives the call announcement request carrying the audio package information sent by the server, and requests the media gateway to play the announcement to the announcement listener. The sound packet information includes sound playing service parameters, such as a URL address.

[0060] Step S20, obtaining the phoneme list information, cod...

Abstract

The invention discloses a calling playback control method comprising the steps as follows: a media gateway receives a calling playback request carrying voice package information; voice element list information, encoding and decoding information and voice element number information associated with the voice package information are acquired according to the calling playback request; a corresponding voice element file is selected according to the voice element list information, the encoding and decoding information and the voice element number information, and thus the media gateway plays the voice element file to a playback listening terminal after performing calling TC resource analysis and continuing treatment. The invention also discloses a calling playback control device. According to the method and the device provided by the invention, when the media gateway playback business of a cloud computing platform is in use, the media gateway directly sends a code pattern data flow needed by playback to RTP, code pattern conversion treatment is not performed in a virtual machine, encoding and decoding conversion resources are saved, playback efficiency is sped up, occupancy of CPU and other hardware resources by the virtual machine is reduced, and thus a resource utilization rate of a physical hardware platform is improved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a call playback control method and device. Background technique [0002] With the development of mobile communication technology and the increase of telephone penetration rate, users have higher and higher requirements for telecommunication services, and the call playback service has become an important telecommunication service. At present, in the cloud computing platform, when the media gateway plays the call, it has the function of TC (Transcoder) codec conversion for the interactive code pattern of the media stream, including the management call playback using the G.711 single decoding format file The phoneme file, and directly use the connection mode of RTP (Real-time Transport Protocol)-TC-TONE in the virtual machine to play the call. That is, on a virtualized hardware platform, the TC processing of audio files is directly performed in the virtual mach...
