The SCF sends the RequestReportBCSMEvents to the service switching entity, so that the service switching entity monitors the related event and reports it to the SCF when the event is triggered.

The process shown in Figure 2 omits some steps for the SCF to interact with the user through the service switching entity (including playback, playback, etc.). The above process is prior art and therefore will not be described in detail here.

Step 3: The SCF sends an AC message carrying the informationToSend to the service switching entity.

The SCF sets the prompt voice of the multi-lingual variable tone to be played by the user according to the scenario and service characteristics of the current intelligent service, and delivers the prompt voice ID of the multi-lingual variable tone to the service switching entity;

The prompt voice of the multi-lingual variable tone may also be preset, and the prompt voice of the multi-language variable tone to be played is set for various intelligent services according to the application scenarios of various intelligent services, and the application scenario of the smart service includes intelligence. The function to be implemented by the business, or the specific user or business control point. The set multi-lingual variable tone prompt voice includes but is not limited to: last minute play/balance reminder, call duration prompt (including duration of call duration and remaining call duration, etc.), play specified Tone alert tone ID, and other Prompt sounds related to business characteristics. When the specific intelligent service is executed, the corresponding prompt voice is selected from the preset prompt voice (can be selected according to the current smart service scenario and service characteristics).

Step 4: The SCF sends a connection message Connect to the service switching entity to connect the call.

Step 5: After the call is established, the service switching entity plays the prompt voice specified in informationToSend to the user during the call process, when the playback duration and playback conditions specified in the AC are reached.

The embodiment of the invention expands the AC, and sets the prompt voice of the multi-lingual variable tone for the smart service according to the application scenario and service characteristics of the intelligent service, which is more friendly and more intuitive to the user, and the prompt is more clear, and the original CAMEL protocol is avoided.
