Abstract
The invention provides a method and a device for individually playing an audio for a user in an audio conference. The method for individually playing the audio for the user in the audio conference comprises the following steps that: a media service control unit adds a switching media resource unit into a conference group according to a received instruction for individually playing the audio for a designated user terminal in the conference group, and the switching media resource unit is set to only transmit audio data to a media resource unit which corresponds to the user terminal; the media service control unit reads the audio data according to the received instruction and sends the audio data to the switching media resource unit; the switching media resource unit sends the received audio data to the media resource unit which corresponds to the user terminal; and the media resource unit transmits the received audio data to the user terminal. By adoption of the invention, the individual playing of the audio for the user in the audio conference can be realized.
Description
Technical field
The present invention relates to data communication field, relate in particular to a kind of method and apparatus of the independent audio plays of user in audio conferencing.
Background technology
Fig. 1 is the existing structural representation that comprises the soft exchanging system of media server, comprise: application server (Application Server, abbreviation App), media server (Media Server is called for short MS), soft switch (Softswitch is called for short SS) and media gateway.
The logic that application server is responsible for various value-added services and IN service produces and management, and provide API (the Application Programming Interface of various openings, application programming interface), the exploitation for third party's business provides authoring platform.Application server is an independently assembly, and is irrelevant with the soft switch of key-course, thereby realized business and called out separating of control, helps the introducing of new business.
Media server is the autonomous device that the specialized media resource function is provided in the soft exchanging system, it also is the visual plant in the packet network, medium processing capacity in the fundamental sum enhancing business is provided, comprise various resource functions and communication function and management maintenance functions such as conversion between the transmission, meeting, different code decode algorithm of DTMF (Dual Tone Multi Frequency, the dual-tone multifrequency) collection of signal and the generation of decoding, signal tone and transmission, recorded announcement.Media server provides on the IP network and to realize the required specialized resource function of miscellaneous service under the control of application server, and it has resource function, the function that communicates with other entities and the Operations, Administration and Maintenance function that resource itself is provided.
Soft switch is the nucleus equipment of Circuit Switching Network to Packet Based Network evolution, it also is one of visual plant of Next Generation Telecommunication Networks network, it is independent of the bottom bearing protocol, mainly finish major functions such as calling out control, media gateway access control, resource allocation, protocol processes, route, authentication, charging, and business and diversified third party's business that can provide the available circuit switch to provide to the user.
Media gateway becomes the desired media formats of another kind of network with the media conversion in a kind of network.For example: media gateway can be changed between the Media Stream of the bearer path of Circuit Switching Network and Packet Based Network, can handle sound, video data or protocol data T.120, the ability that also can possess the combination in any of handling this three, can carry out the media translation of full duplex, can demonstration video/audio message, realize other IVR function, also can carry out media conference etc.
Existing media server comprises: signaling retransmission unit, media services control unit (Media Service Control Unit, abbreviation MSCU), media resource unit (Media Resource Unit, be called for short MRU) and media store transmission unit (Media Storage Transmit Unit is called for short MSTU).
SIP (the Session Initiation Protocol that the acceptance of signaling retransmission unit sends over from application server, the session layer signaling control protocol) signaling, transmit rule according to certain, to trigger the signaling that application server sends over by different user and be forwarded on the different media services control units, to realize load balancing.
The media services control unit is mainly finished management, the maintenance function of carrying out the function of capability negotiation and resource itself is provided with other entities.The media services control unit is handled Resource Unit, and functions such as playback, recording, meeting are provided.
The media resource unit is resource veneer in the media server, mainly bears audio coding decoding conversion, DTMF collects the digits and the meeting sound mixing function.
The media store transmission unit is mainly born the storage and the transformation task of voice data.
At present, in the prior art, each user terminal in the conference group respectively and media resource unit correspondence separately, for example, user terminal A and media resource unit MRUA correspondence, user terminal B and media resource unit MRUB correspondence, user terminal C and media resource unit MRUC correspondence.Intercom mutually between media resource unit MRUA, media resource unit MRUB and the media resource unit MRUC.
Application server sends the instruction to the user terminal A audio plays in the conference group, the media services control unit of media server is according to the instruction that receives, voice data is directly sent to the media store transmission unit, transmit this voice data by the media store transmission unit and give user terminal A.
The audio frequency that user terminal A is play can be transferred to other media resource unit by its corresponding resource unit, each media resource unit sends voice data to each corresponding user terminal by the media store transmission unit again, and each user terminal is play this voice data simultaneously.
Adopt prior art can not make a certain user in the conference group can hear audio frequency, and other users in the conference group can't hear this audio frequency, promptly can not be to the independent audio plays of the user in the audio conferencing, and can only be to user's audio plays all in the audio conferencing.
If only wish that certain user hears audio frequency separately, can only notify this user to withdraw from audio conferencing, treat that this user withdraws from behind the audio conferencing again to the independent audio plays of this user, but so just make this user just can not normally participate in audio conferencing.
