Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
The known VXML document definition that generates by the HTTP/SIP server broadcast logic of MRS when realizing voice interactive function such as PA and PAC, MRS by resolve the VXML file just can be informed in user's voice reciprocal process in how to notify and how to collect the information that the user imports for the user broadcasts.Described VXML file has comprised static and dynamic two parts, wherein, static part has defined the syntax and semantics of the VXML file that MRS need resolve, the voice play function of the corresponding same type of this part content is identical, for example the grammer of the VXML file of the PA of all same types calling use partly is identical, and the grammer that the PAC of all same types calls out employed PAC file partly is identical; The concrete parameter that dynamic part has then defined MRS when realizing voice interactive function such as PA and PAC, mainly comprise: the file that MRS broadcasts for the user in interactive voice processes such as PA and PAC, the parameter that in the PAC process, sets for MRS collection user's input information, and the required parameters of operation such as the processing of the retry in the above-mentioned voice interactive function, timeout treatment, therefore, though different callings uses the static part possibility of VXML file identical, its dynamic part should be different.
Based on the above-mentioned fact, a preferred embodiment of the present invention has provided a kind of method that realizes interactive voice in NGN, and as shown in Figure 2, this method mainly comprises following step:
A, AS are that the voice interactive function of each type generates a VXML file template in advance.
Wherein the voice interactive function of each type is corresponding with a VXML file template, and the VXML file template that is generated also comprises static part and dynamic part, the static part of the VXML file that the HTTP/SIP server is generated in its static part and the prior art is identical, is to have defined the VXML syntax and semantics part that need resolve when MRS realizes all kinds voice interactive function; Its dynamic part is the variable for replacing in the interactive voice process then.
B, after generating the VXML file template of corresponding all kinds voice interactive function, AS is loaded into the VXML file template that generates on the MRS.
In this step, described loading procedure can adopt the mode of HTTP also can adopt the mode of SIP to realize.
C, MRS at first resolve the VXML file template that is received after receiving the VXML file template of described corresponding all kinds voice interactive function in advance, and pre-analysis result buffer memory is got up.
In pre-process of resolving, MRS only needs to resolve the static part of VXML file template, promptly only resolves the syntax and semantics of each VXML file template, and the variable of its dynamic part is retained among the result of pre-parsing.
D, when AS is transferred to MRS with user's calling, AS can be simultaneously sends to MRS with the VXML file template title of corresponding this calling and each parameter of replacing dynamic part variable on this VXML file template; The parameter that the MRS use receives is replaced each variable in the corresponding pre-analysis result of VXML file template, obtains the mutual broadcast logic of this voice calls, and finishes the interactive voice process one time according to the broadcast logic of resulting voice interactive function.
Fig. 3 has shown the detailed process of a voice interactive function of the described realization of step D.As shown in Figure 3, this method mainly comprises following step:
Step 301: Client-initiated, the calling that need carry out interactive voice are forwarded to AS.
After step 302:AS judges these calling needs MRS support according to the relevant information of this calling, send Invite message to MRS, and in the URI of this Invite message, carry this and call out corresponding VXML file template title and each parameter of replacing this VXML file template dynamic part variable.
Step 303: after described MRS receives Invite message, set up RTP with the user terminal of initiating this calling and be connected.
Step 304:MRS reads the VXML file template pre-analysis result corresponding with the described VXML file template of step 302 title from the pre-analysis result of each VXML file template of self buffer memory, and use each parameter receive to replace each variable in the pre-analysis result of this VXML file template, obtain the complete broadcasting logic of corresponding this interactive voice.
The described order that replaces with according to each parameter of receive of this step is replaced each variable that keeps in the pre-analysis result of described VXML file template one by one.
Step 305:MRS connects by the RTP that sets up in step 303, broadcasts notice according to the interactive voice broadcasting logic that step 304 obtains for the user, finishes the interactive voice process one time.
If above-mentioned interactive voice process is PA, then when the notice broadcasting finished, this interactive voice process just was through with.And if above-mentioned interactive voice process is PAC, then after the notice broadcasting finished, MRS also needed further to receive the user by the user terminal feedack, for example, and numeral that the user transfers to by phone or the like.
Step 306: in above-mentioned broadcasting notice or after receiving information process and finishing, MRS will notify this interactive voice process of AS to finish.Described notice can be finished by information (INFO) message of SIP or (GET) message of obtaining of HTTP.
Step 307: if AS asks interactive voice process next time in this calling procedure, then AS can by piggybacking method (Piggybacking) will be next time the required VXML file template title of interactive voice process and each parameter of replacing variable in this VXML file template be carried in the response message of SIP INFO or HTTP GET and send to MRS, also can directly send to MRS by new SIP INFO.MRS will return above-mentioned steps 304 after receiving new VXML file template title and replacing each parameter of variable in this VXML file template, connect with user terminal by the RTP that has set up and carry out interactive voice process next time.
From said process as can be seen, the described method of the preferred embodiment of the present invention is by setting up a template for every type voice interactive function in advance, and in advance these templates are loaded on the MRS, make that AS only needs the parameter of variable in template name and the replacement template is sent to MRS in the interactive voice process, just can make MRS obtain complete VXML file, realize described interactive voice process, and not needing to carry out long VXML file acquisition process consuming time, this has reduced the time delay of interactive voice process widely.In addition, owing to MRS can resolve received VXML file template in advance in advance, thereby saved MRS and in the interactive voice process, resolved the process of VXML file, so can further reduce the time delay of interactive voice process.
