Abstract
The invention discloses a method, device and system for realizing the audio transcoding of TTS (Text To Speech), wherein the method comprises the following steps: a media server receives an access request from an application (APP) server and determines a coding and decoding type set which is supported by the media server; the media server receives a TTS service request which is applied by the APP and applies a media service data packet which meets the service type to a TTS server according to the service type of the TTS; and the media server consults with the TTS server according to the coding and decoding type set so as to obtain the consulted audio coding and decoding type, transcodes the media service data packet according to the audio coding and decoding type and then sends the transcoded media service data packet to a terminal. According to the invention, the success rate of accessing the data of the media service data packet by the terminal can be improved.
Description
Technical field
The present invention relates to the communications field, particularly, relate in particular to a kind of audio frequency code-transferring method, Apparatus and system of realizing from Text To Speech TTS.
Background technology
Media server is used for all medium relevant with audio frequency and video to be handled, and comprises that video and audio frequency RTP data flow to the mutual conversion of looking audio file.Simultaneously, also be responsible for to receive the DTMF input of user by terminal, play service the guiding voice, show dynamic guide picture.Mutual with the user that Session Initiation Protocol that it has and MSML/MOML ability make that it can finish the whole session process under the control of application server APP.
Media control unit (MSCU) is a significant element in the media server, mainly finishes with other entities and carries out capability negotiation, management, the maintenance of resource itself is provided and controls the function that complicated business is finished in other service resources unit.
Media store transmission of audio unit (MSTU-audio) is the service resources unit in the media server, finishes the voice data storage of magnanimity, comprises and realizes the audio file playing function.External network interface is arranged on the media storage unit, can be directly by the external network interface transmitting-receiving on the unit.
Media store transmission of video unit (MSTU-video) is the service resources unit in the media server, finishes the multimedia audio-video storage of magnanimity, comprises realizing the video file playing function.External network interface is arranged on the media storage unit, can be directly by the external network interface transmitting-receiving on the unit.
Now, the use broadcast of media server is very wide.Mainly can reduce audio frequency and video and play, collect the digits and function such as meeting.
From the function of Text To Speech (Text To Speech abbreviates TTS as) is that the text message that will import identifies, and is converted into voice messaging, and voice medium is sent to the user.At field of telecommunications, the application of TTS is special TTS server of configuration substantially at present, specifies TTS that voice are sent to the user by signaling and brings in the once business of finishing.
Fig. 1 is the system configuration schematic diagram according to the realization TTS audio frequency transcoding of correlation technique.As shown in Figure 1, the workflow of this system comprises the steps:
Step 101: terminal is initiated call, activates the business of APP.APP initiates operation flow to media server;
Step 102:APP passes through the SIP signaling to media server request TTS business;
Step 103: media server passes through the SIP signaling to TTS server requests TTS resource, and finishes business function by MRCP agreement control TTS server;
Step 104:TTS server sends medium to terminal
More than be at present typical networking and operation flow.The TTS server uses as the external device of media server.APP just initiates to media server in requested service, media server is judged type of service, when type of service is the TTS application, media server is initiated request to the TTS server again, the application resource, and the behavior of control TTS server, the TTS server sends to medium the terminal in a distant place automatically after receiving signaling.
Above flow process can be finished a basic TTS business.But some problems have appearred in the Application Expansion along with business.Such as, the audio capability collection of TTS server causes service fail with the unmatched problem of media server capability set.Because APP is in media server agreement SDP, media server does not also know whether type of service is TTS, so can consult audio frequency parameter with terminal according to the limit of power of oneself.When APP issues INFO when instruction to media server, media server just can identify the TTS type of service, this moment media server by terminal SDP information to TTS server application resource.If the audio capability scope of TTS server does not satisfy the result that media server negotiates with terminal, cause service fail exactly.Such as: it is the G726 form that media server negotiates code/decode type with terminal, but the TTS server is only supported the audio format of G711.。
At satisfying under the situation of business demand of media server at the audio capability collection of TTS server in the above-mentioned prior art, the problem of terminal access media business packet data failure does not also have effective solution at present.
Summary of the invention

Preferably, in the foregoing description, terminal can send the request of multimedia service data bag to APP; APP sends the signaling of access request according to the request of multimedia service data bag to media server, and with the outer port address of MSTU as with the address of terminal interaction.
Concrete, as shown in Figure 2, the detailed operation flow process of this system comprises the steps:
Step S10, terminal is to APP request multimedia service data bag, APP sends the INVITE signaling to media server and carries out media negotiation, media server is by the selected code/decode type of the capability set of self, and with the outer port address of MSTU as with the address of terminal interaction.
Step S20, the APP server sends the INFO request to media server, and the content among the INFO is application TTS business, simultaneously, transfers after the media server identification services type to TTS server application media business packet data;
Step S30, media server and TTS server are held consultation, and control TTS server to carry out text-converted be voice.As shown in Figure 3, this step S30 specifically can comprise the steps:
Step S301, media control unit MSCU consult code/decode type to TTS server initiation session initiation protocol SIP signaling.The audio coding decoding capability set that consult this moment in the INVITE signaling is what media server had, is all code/decode types that MRU supports, and requires the TTS server that the medium bag is sent to media server, and received by MRU.
Step S302, MSCU issues the order of opening the NAT passage to MSTU, and indication will send to terminal (user side) from the data that MRU receives.
Step S303, MSCU issues the transcoding order to MRU.Specify MRU to receive the medium bag that sends over from TTS, and MRU is appointed as the result that negotiations obtains from step S301 with the port audio coding decoding type that TTS connects, and the medium code/decode type exported of MRU is set to the terminal actual needs and receives code/decode type.
Step S304, MSCU sets up the TCP/IP link with TTS.And send instruction to the TTS server by the MRCP agreement, indication TTS server identification text, and the media business packet after will change sends to MRU and holds.
Step S305, TTS server send to the media business packet receiving port of MRU.
Step S306, MRU will carry out transcoding from the medium that the TTS termination is received, and the audio frequency media behind the transcoding is sent to media store transmission of audio unit MSTU receiving port;
After step S307, MSTU receive the audio pack of MRU, directly audio pack is carried out sending to terminal behind the NAT.
By above several steps, terminal just can receive the audio stream that is by text-converted.
At last, media server reports the INFO execution result to APP, and APP sends the BYE signaling to media server simultaneously, discharges resource.Discharge resource at media server to the TTS server requests, the success back is to the APP return results, this moment end of conversation.
