Description

Open Service Creation Environment Device and Control Method for Intelligent Network Service Creation

An object of the present invention is to provide an apparatus and a control method of a service generation environment that can easily develop a service to a service developer when a new SIB is added, deleted or changed in a service development environment for generating an intelligent network service.

The technical field of the present invention is in the field of communication software for quickly and economically developing new services using a service generation environment technology of an intelligent network in creating a telecommunication service.

Communication software is implemented in a real-time distributed environment and has a complex structure, and is developed for a long time by skilled professionals, and it is difficult to add and change maintenance and functions. The intelligent network enables the external computer to perform the service processing function among the call processing function and the service processing function that was previously performed by the exchange, thereby quickly and economically creating and introducing a new service. The structure of the service creation environment in the intelligent network capability-1 of the past describes a service based on SIB, and converts the service logic code from the service description into the specification description language (SDL) to generate the service logic code, It was a structure that organizes tools by functions so that they can be created directly.

As such, the structure of the intelligent network service creation environment is mostly based on the International Telecommunication Union-Telecommunication standardization sector (ITU-T) Intelligent Network Capability-1. Not done. The structure of service creation environment in intelligent network capability-1 directly programs the parts necessary for service specification function, code generation function, and verification function of each tool constituting service creation environment when new SIB is added, deleted or changed. Since it requires a lot of time and effort, and the entire programming structure has to be changed, a lot of time and effort was required to create a service.

The open service creation environment apparatus and structure for creating an intelligent network service of the present invention introduces a framework-based concept.

A framework is a structure that allows new functions to be added in units of components for a specific range of applications to meet ever-changing user requirements and to reduce system maintenance costs. It's a good way. ACE (Application Construction Environment), Y.SCE, and PLATyPus, which are service creation environments for framework-based Distributed Processing Environment (DPE), enable the specification of Object Definition Language (ODL) to create components and define defined objects. Converts to SDL to automatically generate C ++ code templates, or does not use SDL, and directly generates C ++ code templates.

However, these studies have suggested the structure for creating components using IDL (Interface Definition Language) or ODL, but the structure and method of service creation environment for creating services by composition of developed objects. I'm not doing it.

The components of the framework conceptually applied in the present invention are based on the SIB operation defined in the intelligent network capability-2. Each SIB component includes all the features for service specification and code generation. However, since each SIB component itself does not have the meaning of overall service logic, the structure of service creation environment is presented to enable operation through interaction with service creation coordinator defining their relationship.

1 shows a service creation procedure diagram in an open service creation environment according to the present invention. The service creation procedure is largely composed of a service edit 11, a service verification 14, and a service introduction 15.

The service editing step 11 consists of a service description 12 and a service logic generation 13 function. The service description 12 describes the idea of a new service by combining a SIB in which the service designer abstractly expresses the target network capabilities. The service logic generation 13 automatically generates a service logic program that can be executed in the intelligent network platform from the service technology. The automatically generated service logic program is C ++ code. The service verification 14 verifies the service logic by simulating the generated service logic in a test bed having the same function as the intelligent network platform. Only the service logic verified through the service verification process 14 is introduced into the intelligent network platform, and the service logic program having an error returns to the service editing process 11 to correct the error. The service introduction 15 downloads the verified service logic to each physical entity constituting the intelligent network.

2 is a block diagram of an open service generation environment apparatus for generating an intelligent network service. The open environment for service component integration (OpenSCI) device 21 is largely composed of a service generation environment device 22 and a service verification device 29.

The service generation environment apparatus 21 is composed of a service generation coordinator 23 and an SIB component 24, which act as clients and servers. The client is a service creation coordinator 23 and the server is a SIB component 24. The SIB component 24 is a place for generating and storing SIBs necessary for describing an intelligent network service. The service generation coordinator 23 describes the service 25 by calling the interface for the service specification present in the SIB component 24 through the communication device 27 through the SIBs that have been developed through the SIB component 24.

The communication device 27 used in the present invention communicates through an object request broker, and in the present invention uses a Microsoft Common Object Model (COM). The service description 25 is based on the SIB operation. The SIB operation is a unit smaller than the SIB, and one SIB includes one or more SIB operations.

In order to generate (26) the service logic program from the overall service logic completed by the combination of the SIBs in the service generation coordinator (24), the SIBs that have been developed through the SIB component (24) through the communication device (27) The service logic program is automatically generated (26) by calling an interface for generating code existing in The automatically generated service logic program (SLP) 28 is in the form of C ++ code. The service logic program 28 automatically generated through the service generation environment device 22 is used for the service verification 30 of the service verification device 29. The service verification apparatus 29 has real-time SIB objects for executing the service logic program 28, and is distinguished from the SIB of the SIB component 24.

As shown in FIG. 3, the structure of the service generating apparatus is divided into a service generation coordinator portion that describes a general service logic (GSL) or generates a service code by combining each SIB component-related portion and each SIB component. do.

One SIB component 24 includes a SIB visual processing block 39 for outputting the selected SIB to the screen, a SIB save / read block 40 for storing the generated SIB and reading the stored SIB, and a SIB. SLP code generation block 41 for generating a service logic program code to be coded, a user event processing block 42 for processing the input event by defining an event input by the user using a mouse or keyboard, and the user event A SIB parameter processing block 43 for editing the SIB parameters by the SIB, a SIB registration / deletion block 44 for registering or deleting the developed SIB, and a SIB in charge of input / output with the respective blocks. It consists of a component communication management block 38.

In addition, the service generation coordinator 23 which manages a plurality of SIB components to generate a service description and a service logic program, calls and displays the SIB stored in the SIB component, and displays and edits the GSL editing block 31. And a GSL save / read block 32 for controlling the storage and reading of the newly generated SIB and the edited SIB, and a GSL code generation block 33 for controlling generation of code for the overall service logic currently displayed on the screen. A user event processing block 34 for controlling the processing of an event input by a user with a mouse or a keyboard, a SIB connection information management block 35 for managing logical termination information connecting the start SIB and the next SIB; A SIB management block 36 connected to each block to manage information transfer with the SIB component and information transfer with each block, and the SIB management block 36 and the SIB com It consists of a service creation coordinator communication control block 37 for managing communication with the imminent.

Referring to FIG. 3 configured as described above, the interaction between the SIB component and the service generation coordinator developed in the service generation apparatus in the open service generation environment will be described. When the development of the SIB is completed as a component, first, the SIB is registered / deleted in the SIB management block 36 through the SIB registration / deletion block 44. The SIB in the SIB management block 36 is registered / deleted as a proxy SIB. The SIB component communicates with the respective blocks of the SIB component through the service generation coordinator communication management block 37 and the SIB component communication management block 38. This is done. In order to edit the GSL, the service designer first checks whether the SIB to be edited is selected in the GSL editing block 31 and then checks whether the selected SIB is registered in the SIB management block 36, and then services creation coordinator communication management block 37. And through the SIB component communication management block 38 to the SIB time processing block 39.

The SIB time processing block 39 receives a message from the SIB component communication management block 38, processes the message, and writes a function for drawing the SIB on the screen, the SIB component communication management block 38, and the service generation coordinator communication management block. The SIB is displayed on the screen by the transfer to the GSL editing block 31 through the 37 and the SIB management block 36, and the state can be edited.

The GSL save / read block 32 stores / reads the overall service logic completed by the combination of SIBs in an external file. The information for managing the entire GSL is first stored / read in an external file, and the SIB storage / read blocks are stored through the SIB management block 36 and the service generation coordinator communication management block 37. This is done.

The GSL code generation block 33 is for generating codes for the overall service logic drawn on the current screen, and is provided through the SIB management block 36, the service generation coordinator communication management block 37, and the SIB component communication management block 38. The SLP code generation block 40 of all the SIBs drawn on the screen is repeatedly performed.

The user event processing block 34 performs an appropriate operation according to the type of event when the user generates an event using a mouse or a keyboard. This block checks the type of the defined event, and if it is not the event, determines that the event is related to the SIB and delivers it to the user event processing block 42. The user event processing block 42 defines a mouse double click event. When a mouse double click event occurs in this block, the SIB parameter processing block 43 is called to display a dialog box for editing the parameters of the SIB, and edit the parameters through interaction with the user. The SIB connection information management block 35 is for managing logical termination information connecting the start SIB and the next SIB.

FIG. 4 is a process flow diagram for describing or creating a service through an interaction between the service generation coordinator and the SIB component in the open service generation environment apparatus, assuming that the SIB component has already been developed. It develops and registers SIBs as components, deletes SIBs that are not necessary for the overall service logic technology, and when the registration / deletion process of registered SIB components is completed, the user selects various user menus provided by the open service development environment. And a GSL editing process of selecting a SIB, exchanging an SIB generation message with a SIB component, and generating and editing an SIB on a screen, if the selected menu is a GSL editing request; In the case of GSL read / store information of each SIB in the GSL drawn on the current screen and each SIB component performs its own read / store routine, and GSL code generation when the selected menu is GSL code generation. SIB used in SIB generates each SLP code and each SIB component performs GSL code generation process that executes its own code generation routine.

In the SIB registration / deletion process, in order to use the SIB component developed by the user, the SIB component must be registered or deleted 51 in the service generation coordinator. If the registration or deletion 52 of the SIB component is abnormal, the SIB component cannot be used. If the SIB component is normally registered, the SIB component may be used. If the SIB component is deleted, the SIB component is deleted when it is determined that the SIB component is no longer required for the overall service logic technology.

When the registration / deletion procedure of the SIB component is completed, the user selects 53 various user menus provided by the open service development environment. In the menu selection process, the general service logic may be edited (54), the general service logic having completed the description may be read / stored in an external file (67), or the service logic code may be generated (73).

First, when the user edits (54) the GSL, the user selects (55) the SIB to be edited from the SIB palette of the screen. After the user selects the SIB using the mouse and presses the left mouse button on the edit window, an object of the corresponding SIB is created and a proxy SIB is generated (57). When the SIB object is created and the proxy SIB is generated, the SIB generation message is delivered to the proxy SIB, and the service generation coordinator waits until the message is received from the SIB component (58). If the reception result 60 is normal by receiving the SIB generation message 59 from the SIB component 59, a picture representing the SIB is drawn on the screen (61). This is the result of calling the drawing function of the SIB component. When the SIB is drawn on the screen, the user may generate a double click event 62 in the SIB area. The double click event in the SIB area generates a parameter definition dialog of the SIB and receives a parameter value 63 from the user. Once the SIB parameter value input is complete, select the arrow from the SIB palette to associate the starting SIB with the next SIB (64). After connecting the start SIB and the next SIB by using the arrow, the arrow is selected and a double click event is generated (65). When the arrow is selected and a double-click event occurs, a logical end dialog is generated. When the processing is completed by receiving parameters 66 from the user, basic general service logic can be edited. In this way, even if the same double-click event occurs, it recognizes different objects and calls and processes different routines.

If the user requests to read / store the GSL (68), the location information and logical termination information of each SIB used in the GSL drawn on the current screen are read / stored (68). In order to read / store the parameter information of the SIB, the read / store routine of the SIB component is repeatedly called (69) for each read / store routine of each SIB used in the GSL drawn on the screen. It then forwards (70) and waits (71) the read / store message to the proxy SIB. While the service creation coordinator is waiting, the SIB component performs each SIB read / store routine under the control of the service generation coordinator.

When the description of the desired service is completed and the user wants to generate the service logic program (73), that is, the GSL code generation process calls the SLP code generation routine of each SIB used in the GSL drawn on the current screen (74). It then passes (75) and waits (76) a code generation message to the proxy SIB. While the service generation coordinator is waiting, each SIB component performs each SIB code generation routine under the control of the service generation coordinator.

The open service generation environment apparatus and control method for generating an intelligent network service proposed by the present invention includes a service specification and code generation in each SIB component, and defines a service generation coordinator defining relationships between SIB components. It was. Therefore, when the SIB is added, deleted, or changed, addition, deletion, or change is performed in units of SIB components, and since there is almost no change in the service creation coordinator, it is possible to quickly create a service and expand the service creation environment.
