(Operation) In the present invention, by directly activating the service element execution processing means from each service element execution processing means, the structure of the program of the communication processing device that controls and executes the service elements is not complicated. You can do it like this.

〔Example〕

FIG. 1 is a block diagram showing an outline of the configuration of an information communication network including a communication processing device as an embodiment of the present invention. Here, the present invention will be explained by taking as an example a configuration in which attribute information regarding communication services and environment information are temporarily set in memory.

In FIG. 1, 7 is a data transfer memory, which is a memory area for transferring data necessary for communication system <III, such as attribute information and environment information, between service element execution control devices;
8 is an initial data setting device that sets initial data regarding the communication service in the data transfer memory 7 at the time of making a call; 9-0
determines a first service element based on initial data;
A first service element starting device 9-1 to 9-n that starts the corresponding service element execution control device executes processing corresponding to the service element, determines the next service element, and starts the corresponding execution control device. This is a service element execution control device.

When a call is made from the information input/output terminal 1, the exchange 3 connects the terminal to the communication processing device 4. In the communication processing device 4, the initial data setting device 8 stores attribute information (for example, promptness, confidentiality, etc.) regarding the communication service specified by the caller or receiver at the same time as the call or prior to the call, the date and time of the call, the location, etc. Write incidental environmental information to the data transfer memory 7,
The first service element activation device 9-0 is activated.

Next, the first service element starting device 9-0 refers to the information written in the data transfer memory 7, determines the service element to be executed first in the communication service, and controls the execution of the corresponding service element. Activate devices 9-1 to 9-n. When the first service element cannot necessarily be identified from the information written in the data transfer memory 7, service element execution control devices 9-1 to 9-n are candidates for the first service element.
Start. Activated service element execution control device 9-
1 to 9-n execute the processing of the service element they are in charge of if processing is necessary, and after the processing is completed, the processing result,
Alternatively, it determines the service element to be executed next based on the information in the data transfer memory 7 or the service element execution control device from which it was activated, and activates the corresponding service element execution control device. Further, if no processing is required under the conditions of the communication service, the next service element is immediately determined and the corresponding service element execution control device is activated.

Similarly, the service element execution control device started by the previous service element execution control device determines whether processing is necessary, executes the process if necessary, and then starts the next service element execution control device. . In this way, communication is performed by activating and executing the service elements, which are the functional units of the service, one after another.

Note that in this example, the first service element activation device 9-0,
Alternatively, in consideration of the case where the service element execution control devices 9-1 to 9-n cannot specify a single service element to be executed next, each of the service element execution control devices 9-1 to 9-n is activated. When doing so, the user first refers to the data in the data transfer memory 7 and determines whether or not it is necessary to execute the process of the service element that the user is in charge of in the communication service.

FIG. 3 shows an example of the structure of information in the data transfer memory 7. This is an example in which an area is configured to manage attribute information of the communication service instructed by the caller and receiver, and an area to manage incidental environmental information such as call time and destination number.

As the attribute information, attributes such as promptness and confidentiality regarding the communication service are set. The first service element activation device 9-0 determines the first service element or its candidate in the communication service from these attributes or environment information, and activates the corresponding service element execution control device. For example, as shown in Figure 3, promptness is required,
If the call must arrive at the terminal within 5 minutes from the outgoing time, the first service element activation device 9-0 issues service requests related to recordability such as various message generation and display processing, and confidentiality requests such as password specification. Service elements related to quality, such as high-quality mode communication, may be skipped, and the service element execution control device in charge of transfer processing to the terminal may be immediately activated.

Please refer to FIG. 4, which shows an example of the operation of the service element execution control device. Here, each service element execution control device is provided with a service bus management table for managing the flow of service elements in the communication service shown in FIG.

When the service request execution control devices 9-1 to 9-n are activated by the first service element activation device 9-0 or the service element execution control devices 9-1 to 9-n other than themselves, the data transfer memory 7 If the attributes related to the communication service written in are satisfied, it is determined that processing of the service element is necessary, and the processing is executed. After processing is completed,
The processing result, information in the data transfer memory 7, or the activated original service element execution control device is checked against the service bus management table, the next service element is determined, and the corresponding service element execution control device is activated. do.

For example, the service element execution control device equipped with the service bus management table shown in FIG. 5 is started by the service element execution control device in charge of service element A, executes processing,
If the result is normal and attribute 1 is required as the attribute of the communication service, service element a is determined as the next service element (candidate), and the service element execution control device in charge of this is activated. If no processing is required,
Immediately, when environmental condition 1 is present, the service environment C is activated, and when environmental condition 2 is, the service element execution control device in charge of the service element is activated.

[Effects of the Invention] As explained above, according to the present invention, each service element execution control device manages the flow of the communication service of the part related to itself, so that the execution control device of the service element directly Since it is possible to start the next execution control device, complicated sequence management, which was conventionally performed by the central control device all at once, becomes unnecessary, and the program structure does not become complicated. In addition, when adding or changing a service element, it is only necessary to change the service path management table of the service element execution control device that corresponds to the part where the service flow changes, so recompilation, relinkage, etc. There is no need for complicated file updates.
