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.
