The route of voice SMS and handshaking procedure divide following two kinds of situations:
If MS1 user sends voice SMS for strange land MS2 user, MS2 user listens to this voice SMS at its ownership place, and handshaking procedure as shown in Figure 4.
Steps A 1, MS1 inserts A ground VAG-A nearby by communication network;
Steps A 2, VAG-A is routed to A ground speech business platform A, and the speech business platform A provide voice suggestion, and the MS2 number is analyzed in guides user recording, the on-hook then of input called subscriber's MS2 number, and determining MS2 is the strange land user;
Steps A 3, will leave a message information and MS2 Subscriber Number of speech business platform A sends to A ground VAG-A;
Steps A 4, VAG-A analyzes the VAG-B that the MS2 Subscriber Number is searched route and is routed to the MS2 ownership;
Steps A 5 will be left a message and the MS2 Subscriber Number sends to MS2 ownership place B ground speech business platform 2 through VAG-B;
Steps A 6, speech business platform 2 notify other increment service systems (being short messaging gateway in the present embodiment the inside) to send the Wordn short message notice to MS2.
It is as follows that MS2 receives the voice SMS handshaking procedure at ownership place:
Step B1, MS2 user inserts B ground VAG-B nearby by the mobile network;
Step B2, B ground VAG-B are routed to B ground speech business platform B, and the speech business platform B provide voice suggestion, and guides user selects to listen to voice SMS, and analyze the MS2 number, and determining MS2 is the local user; Speech business platform 2 provides authentication and plays the tone information service for MS2.
If MS1 user sends voice SMS for strange land MS2 user, MS1 and MS2 user roam into the other side's ownership place, and handshaking procedure as shown in Figure 5.
MS1 sends the voice SMS handshaking procedure in the roaming place:
Step C1, MS1 inserts B ground VAG-B nearby by communication network;
Step C2, VAG-B is routed to B ground speech business platform B, the speech business platform B provide voice suggestion, guides user recording, the on-hook then of input called subscriber's MS2 number, speech business platform B analyzes the MS2 number, determine MS2 and be local user (if MS2 is the strange land user, then follow-up transmission handshaking procedure with step A3 to A6);
Step C2, speech business platform B informing message gateway sends the Wordn short message notice to MS2.
MS2 receives the voice SMS handshaking procedure in the roaming place as follows:
Step D1, MS2 user inserts A ground VAG-A nearby by communication network;
Step D2, VAG-A are routed to A ground speech business platform A, and the speech business platform A provide voice suggestion, and guides user selects to listen to voice SMS, and analyze the MS2 number, and determining MS2 is the strange land user;
Step D3, speech business platform A analyzes the MS2 Subscriber Number, and is routed to VAG-A;
Step D4 is routed to MS2 ownership place B ground VAG-B by VAG-A;
Step D5, VAG-B are routed to B ground speech business platform B, and speech business platform B provides authentication and plays the tone information service for MS2.
According to above operation flow, if getting the called subscriber, the calling subscriber belongs to different speech business platforms, listen to the principle of finishing at ownership place according to tone information, require tone information to be inserted the speech business platform and send to called subscriber place speech business platform, listen at dialed field by the called subscriber by the calling subscriber.Therefore require the speech business platform will be stored as voice document after the user speech digitlization, and send voice document to strange land speech business platform by data network or special line.Below the form of the voice document after the digitlization and file packing form and method are described.
It is varied to use ripe compress speech modulation algorithm at present, and the voice document form of recording has files such as " * .vox ", " * .wav ", and its digitlization parameter is as shown in the table.

In note and playing speech on demand value-added service, need after interconnected information transmitted to comprise main following two kinds between the VAG:
A kind of is voice play-on-demand program data file, when certain user when the strange land user sends the playing speech on demand program, voice play-on-demand program data file is sent to dialed field, outgoing call then, called answering, or text SMS is notified the called program of listening to.When directly sending the speech play-on-demand program,, need to consume more Internet resources, therefore need transmit after by the certain format compression the tone information in the voice play-on-demand program because voice file is bigger.The transmission of voice play-on-demand program packet compressed file bag is adopted and set up data channel between VAG, transmits by various protocols such as TCP/IP.According to the situation of network, can pass through transferring voice play-on-demand program packet files such as special line, the Internet.
Another kind is a speech, as user during,, just need between its roaming place and ownership place VAG, set up speech channel if listen to the playing speech on demand program that is kept at ownership place at roaming state, thereby listen to the speech message, adopt the mode of setting up IP phone or special line to transmit.
After note and voice no demand service platform disperse to build, in order to guarantee the consistency of business service, require on the one hand that the voice programme content must keep synchronous renewal in each business platform, on the other hand, must accomplish that at the customization number of each program in voice and the Short-Message-on-Demand library of programmes whole nation is unified.Voice and short message on-demand service Content Management node are responsible for specially provides the voice SMS of all service nodes program integrated management function.
The voice document form of selecting for use is as shown in the table.
| File format | Sample frequency | Modulation algorithm | The companding rate | Coding |
| *.vox | 8KHz | ADPCM | ALaw | 4bit |
| *.vox | 6KHz | ADPCM | muLaw | 4bit |
| *.wav | 8KHz | PCM | ALaw | 8bit |
| *.wav | 6KHz | PCM | muLaw | 8bit |
The filename of voice document will embody the information of document content feature, some broadcast mode, voice document source, voice document form.According to above principle, the filename called after of voice document: ABBBBQQQQQ.vox, use 10 bit representations, wherein the 1st A is information category, value is 0～9, temporary transient at present use 5,6,7,8,9, other values keep, wherein A is 5,8 or 9 o'clock, expression this document is the voice document that is applicable to all service nodes, and the user is all customizable or be other these programs of user's program request under roaming or non-roaming situation, when A is 6 or 7, expression this document is the region voice document, and the user can only be at the customization of voice document location voice platform or this program of program request; Middle 4 numberings that BBBB is an on-demand content, value is 0000～9999; The note program code that ABBBB need import when constituting customization or program request voice program jointly; Next 5 is the SPID of information source, is mainly used in operator's management and waits other users.
After adopting dispersion that the speech business platform is set, in order to realize the unified business that is applicable to all service nodes, each service node information content must keep synchronous renewal, when the user uses service at trans-regional speech business platform, do not need to transmit the voice packet file between the platform yet, the service number information that only needs to transmit customization get final product, and the user can adopt the principle that service is provided by business platform nearby to the visit of business platform, thus the quality that assurance is listened to.
According to above communication process as can be seen, the user may relate to the transmission of user customized information in both cases when using the service of voice and Short-Message-on-Demand:
Be strange land customization voice and Short-Message-on-Demand;
When certain user was strange land customization or program request voice and Short-Message-on-Demand, according to above flow process, customization or IP Information On Demand can at first need to send to the dialed field voice platform, so that the user listens to.Transmit between the strange land of customized information at this moment and adopt File Transfer Protocol, the password or the fire compartment wall of different stage can be set for guaranteeing system safety.The content of transmission is a binary file, below is a kind of naming method.
Filename form: 3AAAAQQQQQYYYYMMDDNNNNNNN.VMI
Wherein: 3AAAAQQQQQ represents the voice platform node serial number, and YYYYMMDD is the date, and NNNNNNN is the sequence number (7) of every day, and what span 0000000-9999999, VMI represented to send is the speech message index file, and its file format as shown in Figure 9.
Another situation is: when the user listens to the playing speech on demand program under roaming state, employing is provided the principle of service by voice platform nearby, the roaming place voice platform provides the service of listening to, because the roaming place voice platform does not directly save as the information of strange land user's program request or customization, therefore require to dial special-purpose Number for access request when listening to the roamer, the roaming place voice platform obtains this user's customization or IP Information On Demand from this user ascription area voice platform.
In order to improve the message transmission efficiency, reduce the time delay of strange land when listening to as far as possible, this moment, information interaction adopted the mode that message is transmitted.
Note and voice no demand service can adopt information charge, communication expense or mode that both combine to charge.
