2. Description of the Related Art The quality of a program affects the quality of a product to be mounted. Once a program failure occurs in a product on the market, not only does the user suffer much trouble, but also the manufacturer loses the user's trust. So the loss is immeasurable.

[0003] In addition, in order to supply products to the market in a timely manner in anticipation of market requirements, manufacturers need to develop programs efficiently.

In order to develop programs efficiently,
It is effective to divert an existing high-quality program asset, thereby improving productivity and providing a high-quality product to a user.

[0005] Against this background, for example, program specifications are divided into functions, a program component is created as a set of a processing purpose and a processing module in functional units, and stored in a database. Japanese Patent Application Laid-Open No. 6-214768 proposes a technique for searching a database using a processing purpose of a function division unit of a new specification as a search key during development and extracting necessary processing modules from a large number of processing modules and assembling them. ing.

Problems to be Solved by the Invention Japanese Patent Laid-Open No. 6-21476
In the program part creation method and the program automatic generation method disclosed in Japanese Patent Application Laid-Open No. 8-203, when a new program is developed, a database is searched using the processing purpose of the function division unit of the new specification as a search key, and the processing purpose of the function unit and the processing module are determined. The necessary processing modules are extracted from a number of existing program parts that make up a set, and assembled to complete a new program. Therefore, in the case of similar functions, similar programs are synthesized, and individual programs are included in each program. Parts of the same processing will be duplicated.

Therefore, a large number of similar programs are mounted in a limited storage area, and the storage area may be insufficient.

For example, in the case of an exchange providing a large number of additional services, it becomes difficult to add additional services, and it is necessary to change to a storage device having a large storage capacity.

In the case of the supplementary service of the exchange, if the program is divided into functional units, that is, the supplementary service unit, the processing part may be duplicated in each supplementary service program, and the storage device cannot be used effectively.

[0010] An object of the present invention is to make it possible to share a common processing part of a program having a similar function in a program for additional services of an exchange, and to describe a plurality of parts that cannot be shared by describing a difference processing of each. A similar program to be described can be described as one program, commonality in the program is achieved, and unnecessary similar processing portions of the synthesized program are reduced.

[0011]

SUMMARY OF THE INVENTION A method for generating an additional service program for an exchange according to the present invention is directed to processing for implementing the additional service when creating a program for an additional service of a certain exchange requested by a user. The method is characterized in that the processing is divided into units and made into components, and the processing of the processing target units made into components is combined into a processing order for realizing the additional service.

Further, processing for realizing the supplementary service is subdivided into processing target units to form components, and processing is performed from a plurality of existing similar additional service programs in which the processing of the component processing target units is synthesized in the processing order. The processing target unit is extracted in common with the processing target unit, and the processing target unitized in different processing target units is extracted. A common pattern number for each processing part, and a pattern number for uniquely identifying each processing to each processing part having a different processing target unit. Combining the processing part with a common target unit and the processing part with a different processing target unit into a processing order that realizes supplementary services, Characterized in that it formed.

An additional service program for an exchange for providing various services to a user is provided by subdividing a process for realizing the additional service into processing target units to form a component, and processing a processing part of the componentized processing target unit. In order to specify, a processing portion having one common processing target unit to which one common pattern number is assigned, and individual processing having different processing target units each having a pattern number uniquely identifying each process. To specify one or more sub-scenarios of an additional service unit whose parts are described in a processing order for implementing the additional service, and a sub-scenario corresponding to an arbitrary additional service from the sub-scenarios of the additional service unit Service identifier and the processing component described in the sub-scenario in which the processing target unit is different from each other. A plurality of sub-scenario identifiers comprising: a pattern number identifier; a sub-scenario number identifier for identifying one sub-scenario from the one or more sub-scenarios of the supplementary service specified by the service identifier; For each processing event that occurs when executing a service, the corresponding sub-scenario and the processing target unit described in this sub-scenario are different from the pattern number identifier and the sub-scenario number identifier of the sub-scenario identifier. The service scenario is characterized by comprising a service scenario in service units consisting of an analysis scenario for designating a pattern number of a processing portion.

[0014] Further, the present invention is characterized in that a plurality of the analysis scenarios are provided corresponding to each processing event that occurs when the additional service is realized.

The control method of the supplementary service program of the exchange according to the present invention includes a service scenario section for storing the supplementary service programs of the plurality of exchanges, and an analysis and transmission of the signal information received from the telephone terminal, a transmission path connection and the like. When a basic call process is performed and the analysis result of the signal information is an exchange supplementary service request, a basic call control unit that transfers the received signal information, and the signal information that is transferred from the basic call control unit are received. After identifying the supplementary service requested by the telephone terminal from the received signal information, identifying the presence or absence of the supplementary service subscription of the supplementary service-requested telephone terminal, and when the supplementary service subscription is registered, The service of the sub-scenario identifier of the supplementary service program stored in the service scenario section in plural types. When the identifier is searched to identify a service identifier corresponding to the supplementary service requested by the telephone terminal, selection of the sub-scenario of the supplementary service identified for the analysis scenario and supplementary service described in the selected sub-scenario And a service control unit that instructs execution of the processing.

Further, when the execution scenario of the supplementary service is received from the service control unit, the analysis scenario is based on the sub-scenario number identifier and the pattern number identifier described in the sub-scenario identifier together with the service identifier. A corresponding sub-scenario and a pattern number are identified, and the identified pattern number is notified to the identified sub-scenario, and the sub-scenario is a processing with a different processing target unit to which the notified pattern number is assigned. The part and the processing part having the same processing target unit are executed in the order described.

As described above, an identifier for identifying a sub-scenario is assigned to a program called a sub-scenario that is subdivided into processing units for each service for realizing the exchange supplementary service. The identifier consists of a number for identifying a supplementary service program of the exchange called a service scenario, a number for identifying a sub-scenario, and a pattern number for identifying a subdivided unit in the sub-scenario program. I do.

In the program of the sub-scenario, portions having common processes are shared, and processes of different portions are described by giving pattern numbers.

Thus, a program having a similar function can be described as one program. Only by changing the specified sub-scenario identifier, it is possible to execute a partially different program. Therefore, the number of programs to be created is reduced, and the programs can be mounted in a limited storage area of the exchange.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram of a service scenario that is an additional service program of the exchange according to the present invention. Service scenarios 10-1 to 10-n for additional service units
Are sub-scenario identifiers 20-1 to 20-n for specifying supplementary services, sub-scenarios 40-1 to 40-n which are programs for implementing supplementary services,
It is composed of analysis scenarios 30-1 to 30-n, which are programs for performing analysis processing for determining the sub-scenario.

The analysis scenarios 30-1 to 30-n are defined for each event that occurs in the exchange in order to determine which sub-scenario is to be activated. Here, each event refers to an event that occurs in the exchange in response to various operation information including a call, hold, call termination operation, and additional service selection of a telephone terminal accommodated in the exchange.

The sub-scenarios 40-1 to 40-n
Is composed of a componentized program that is executed when additional service designation information is received from a telephone terminal.

FIG. 2 is a diagram showing a configuration example of one sub-scenario shown in FIG. A sub-scenario of a certain additional service, for example, 40-1 includes a process A41, a process B42, a process C
43, a process D44, and a process E45, each of which is composed of a program that is made into a component, and each of the processes that are made into components is assigned a number, which is called a pattern number, that specifies a process in a sub-scenario.

The assignment of the pattern number is common among existing sub-scenarios when a new additional service program is created from a plurality of existing sub-scenarios that are programs for implementing the additional service. A pattern number 0 is assigned to a sub-scenario, and a unique pattern number 1, 2, or 3 other than the pattern number 0 can be identified for a process that is not common between existing target sub-scenarios.

For example, in sub-scenarios 1, 2, and 3, which are similar types of existing additional service programs as shown in FIG. 7, processing A exists only in sub-scenario 1.
Process B and process D exist in common in sub-scenarios 1, 2, and 3; process C exists in sub-scenarios 1 and 2; process E exists in sub-scenarios 2 and 3; Exists only in scenario 1.

Conventionally, programs (sub-scenarios 1, 2, and 3) are conventionally created in units of functions as described above. Therefore, each sub-scenario includes processes B and D common to each other, and a common process portion is included. It is not used effectively, and the storage area of the storage device is wasted.

Therefore, the sub-scenarios 1 and 3 which are similar types of existing supplementary service programs shown in FIG.
When a new supplementary service program is created by combining steps 2 and 3, if the newly created supplementary service program is configured in the order of processes A, B, C, D, and E,
As shown in FIG. 2, pattern number 1 for processing A, pattern number 0 for common processing B, pattern numbers 1 and 2 for processing C, pattern number 0 for processing D, and pattern number 2 for processing E By adding and combining
The common processing portion can be used effectively, and a limited storage area can be used effectively.

FIG. 3 is a diagram showing a configuration example of the sub-scenario identifier shown in FIG. Sub-scenario identifier assigned to uniquely identify a sub-scenario, for example, 20-1
Is composed of a service identifier 21 for identifying a service scenario, a sub-scenario number identifier 23 for identifying a sub-scenario, and a pattern number identifier 22 for specifying a process in the sub-scenario.

The service identifier 21 is assigned to each additional service unit of the exchange, and the sub-scenario identifier 23
Is provided for each sub-scenario constituting one service scenario.

Therefore, these three identifiers (21, 22,
23) Sub-scenario identifier 20-1
Is unique and the same identifier cannot exist, so that the sub-scenarios do not overlap.

FIG. 4 is a diagram showing a main configuration of an exchange for controlling a service scenario. The control configuration of the exchange shown in FIG. 4 includes a call control unit 50 and a service scenario unit 60.

The call control unit 50 includes a basic call control unit 51 that performs basic exchange processing such as signal information analysis, signal transmission, and communication path connection when receiving a signal from a telephone terminal, a service scenario activation determination, a contention determination, and the like. Service scenario 10-
The service control unit 52 performs the management processing of 1 to 10-n.

The management of the contention determination means, for example, rejecting the request for the call waiting service when the request for the additional service of the call waiting service is made during the execution of the additional service of the transfer service.

The service scenario section 60 includes a sub-scenario identifier 20- for specifying the supplementary service shown in FIG.
1 to 20-n, analysis scenarios 30-1 to 30-n for analyzing the service scenario to be activated, and sub-scenarios 40-1 for performing processing for realizing additional services.
40-n, a plurality of service scenarios 10-1 to 10-n.
10-n.

Next, the control procedure of the sub-scenario will be described with reference to FIGS.

First, the call control unit 50 receives various operation information from the telephone terminal at S101, and the basic call control unit 51 of the call control unit 50 identifies whether or not an additional service request is made by, for example, a service special number, and If the request is a service request, the operation information is transferred and the service control unit 52 is activated (S102).

The service control unit 52 specifies the requested additional service from the operation information transferred from the basic call control unit, searches the subscriber data (not shown), and identifies whether or not there is a contract for the specified additional service. I do. If the requested additional service contract has been registered, the service scenario 10-
Sub-scenario identifiers 20-1 to 20-n of 1 to 10-n
And analyzes whether there is a service identifier 21 corresponding to the received additional service request (S10).
3).

The service control unit 52 includes sub-scenario identifiers 20-1 to 20-2 of the service scenarios 10-1 to 10-n.
As a result of searching for 0-n, if there is a sub-scenario identifier, for example, 20-1, in which the corresponding service identifier 21 is described, the analysis scenario, for example, 30-1 is instructed to select a sub-scenario corresponding to the service identifier. . If there is no sub-scenario identifier corresponding to the received supplementary service request as a result of the analysis in step S103,
Without activating the analysis scenarios 30-1 to 30-n, the fact is notified to the basic call control 51 and the processing is terminated.

The analysis scenario 30-1 which has received the sub-scenario selection instruction analyzes the description contents of the sub-scenario number identifier 23 and the pattern number identifier 22 recorded together with the service identifier 21 in the sub-scenario identifier 20-1 ( (S104), it is determined whether or not there is a corresponding sub-scenario among the sub-scenarios 40-1 to 40-n (S10).
5).

When the analysis scenario 30-1 identifies the corresponding sub-scenario, for example, 40-1, the process of the sub-scenario 40-1 is executed by designating the sub-scenario number identifier 23 and the pattern number identifier 22 (S106). ). In step S105, the corresponding sub-scenario 20-1
Is not present, the sub-scenarios 40-1 to 40-n
Is not started, the service control unit 52 of the call control unit 50 is notified of the fact, and the process is terminated.

Next, processing of a sub-scenario in which a sub-scenario number identifier and a pattern number identifier are specified will be described with reference to FIG. FIG. 2 is a diagram illustrating a program configuration example of a sub-scenario. For example, a sub-scenario 40-1, which is a program of an additional service, includes a process A41 to which pattern number 1 is assigned, a process B42 to which pattern number 0 is assigned, a process C43 to which pattern numbers 1 and 2 are assigned, Process D with pattern number 0
44 and processing E4 to which pattern numbers 2 and 3 are assigned
And 5.

Here, the pattern number 1 indicates a process for, for example, an additional service request from the telephone terminal, the pattern number 2 indicates, for example, a process for a hold operation of the telephone terminal during the additional service, and the pattern number 3 indicates, for example, a telephone terminal. It is assumed that the processing is for the call termination operation.

The analysis scenarios 30-1 to 30-n
Corresponds to various events that occur inside the exchange according to the telephone terminal operation information.
It is assumed that 0-1 shares the processing for the supplementary service request, 30-2 analyzes the processing for the hold operation, and 30-3 analyzes the processing for the call termination operation.

The service control unit 52 of the call control unit 50 identifies a certain additional service request from the telephone terminal, identifies the corresponding additional service subscription registration, and searches the service scenario unit 60 for the sub-scenario identifier of the service scenario. Then, when the corresponding service identifier is identified, the analysis scenario 30-1 is instructed to select the sub-scenario corresponding to the identified sub-scenario identifier 20-1.

The analysis scenario 30-1 is composed of sub-scenario 2
0-1 identifies the description contents of the pattern number identifier 22 and the sub-scenario number identifier 23 described together with the service identifier 21 and processes the pattern number 1 of the sub-scenario 40-1 described in the sub-scenario number identifier 23 Instruct.

The sub-scenario 40-1 first executes the process A41 in which the pattern number 1 shown in FIG. 2 is described, and then executes the process B42 of the pattern number 0 described as a common process of the sub-scenario. Then, a process C43 in which the pattern number 1 and the pattern number 2 are described is executed, and finally, a process D44 of the pattern number 0, which is described as a common process of the sub-scenario, is executed. Terminates the processing of the supplementary service requested from.

When the telephone terminal performs a hold operation during the supplementary service, the service control unit 52 of the call control unit 50 instructs the analysis scenario 30-2 to execute a service hold process. The analysis scenario 30-2 includes the sub-scenario identifier 20
-2 identifies the description contents of the pattern number identifier 22 and the sub-scenario number identifier 23 described in the sub-scenario 40-
The processing of the putter number 2 of 1 is instructed.

The sub-scenario 40-1 first executes a process B42 of pattern number 0 described as a common process of the sub-scenario shown in FIG.
Is executed, then the process D44 of the pattern number 0 described as the common process of the sub-scenario is executed, and the process E45 in which the pattern number 2 is described is executed and the process is suspended. The process ends.

When the supplementary service is completed and the telephone terminal performs a call end operation, the service control unit 52 of the call control unit 50 instructs the analysis scenario 30-3 to execute a service hold process. The analysis scenario 30-3 identifies the description contents of the pattern number identifier 22 and the sub-scenario number identifier 23 described in the sub-scenario identifier 20-3, and the sub-scenario 4 described in the sub-scenario number identifier 23.
The processing of the pattern number 3 of 0-1 is instructed.

The sub-scenario 40-1 first executes the processing B42 of the pattern number 0 described as the common processing of the sub-scenario shown in FIG.
Is executed, and finally, a process E45 in which the pattern number 3 is described is executed to end the end-of-call process.

If no pattern number is specified, the processing is executed in the order of processing B42 and processing D44 in which pattern number 0 is described.

Next, another configuration example of the sub-scenario will be described with reference to FIG. In FIG. 6, a process for defining and executing a pattern number is described among the processes specified by the pattern number.

A sub-scenario, for example, 40-2 which is a program of an additional service shown in FIG.
, A common process B47 of pattern numbers 1 and 2 to which pattern numbers 1 and 2 are assigned, and a process B47 designated by pattern numbers 1 and 2, respectively. Processing C47-, which is a difference processing of pattern numbers 1 and 2 in which processing is defined as pattern number 1
1 and processing D48 to which pattern number 3 is assigned.

In this state, for example, analysis scenario 3
0-1 is, for example, the pattern number identifier 22 and the sub-scenario number identifier 2 described in the sub-scenario 20-1.
3 is identified, and processing of the pattern number 1 of the sub-scenario 40-2 described in the sub-scenario number identifier 23 is instructed.

The sub-scenario 40-2 receiving the processing instruction of the pattern number 1 is the processing A46 of the pattern number 0 described first as the common processing in this sub-scenario.
Is executed, and then a process B47 described as a common process of the pattern numbers 1 and 2 is executed.
7 is executed, the process C47-1 described as the process of only the pattern number 1 is executed, and the sub-scenario 40-2 is executed.
Is completed.

The analysis scenario 30-2 identifies the description contents of the pattern number identifier 22 and the sub scenario number identifier 23 described in the sub scenario 20-2 and is described in the sub scenario number identifier 23. When the processing of the putter number 2 of the sub-scenario 40-2 is instructed, the processing A46 to which the pattern number 0 is given is executed, and the processing B47 to which the pattern number 2 is given subsequently.
To end the processing of the sub-scenario 40-2.

Similarly, when the instruction of the process of the pattern number 3 is received, the process A46 is executed, then the process D48 is executed, and the process of this sub-scenario is ended.

If no pattern number is specified, only the process A42 for pattern number 0 is executed, and the sub-scenario process is completed.

[0059]

As described above, according to the present invention, the processing for realizing the supplementary service is subdivided into processing target units to be made into components, and the processing of the componentized processing target units is combined in the processing order to the existing similarity. From the plurality of additional programs, a processing part in which the processing target unit is common and a processing part in which the processing target unit is different are extracted, and the processing part of each extracted processing target unit is specified. Therefore, a common pattern number is assigned to a processing portion having the same processing target unit, and a pattern number capable of uniquely identifying each processing is assigned to each processing portion having the different processing target unit, A processing part having a common processing target unit and a processing part having a different processing target unit provided with the pattern number are combined into a processing order for realizing the additional service, and the additional service of the exchange is newly added.
