The present invention relates to a method and system for combining static services in an open network, and more particularly, to a method and system for combining static services providing a service to a service user by combining services of a plurality of service providers.

Due to the spread of internet usage and the development of high speed information and communication technology, users' demand for high speed multimedia service is increasing day by day. In addition, users are pursuing customized services that allow the functions of the service to be customized according to their needs and tastes. As a result, service providers' investments and efforts for the rapid provision of new services by service providers and the efficient maintenance of network operators are increasing day by day.

However, these efforts are carried out independently by each service provider, which not only ensures structural homogeneity, but also the structure of services provided in the same service provider domain.

This structural difference does not facilitate the unmodified recycling of existing components in the development of new services. Therefore, in order to improve the recyclability of components and to facilitate the rapid development of new services by service providers, a common service structure that can be applied to various services, that is, an open service structure, should be established first. In addition, in order to meet the user's request for a customized service, a standardized specification for a service combination function that allows each service function to be combined with each other should be prepared.

The open information network structure defines the concepts and principles related to the design, construction and operation of the open information network structure in the communication network as standardized documents. With the recent development of services, researches on service combinations that provide new application services constructed using individual services provided in such an open information communication network environment are being actively conducted.

The open information communication network structure is structured into a hierarchical structure of software based on the hardware of the network device. In each network configuration device, based on the distributed processing environment, a function structure for controlling services, network management resources, and actual network configuration devices was established. These are composed of application services as application objects, and object connections provided by distributed processing environments. The open information communication network structure has a structure of distributed processing environment layer, service structure, network resource structure, and application service object according to network configuration device control.

Research on open service structures and retailer services is being conducted by various domestic and overseas research institutes and organizations, and TINA-C (TINA-C) is one of the most prominent organizations.

TINA-C presents a software hierarchical structure for the various functions provided on the network. The service structure proposed by TINA-C provides service objects that interact in a segmentation processing environment. Thus, the service structure defines how components interact with each other, which is a combination of service objects needed to create a service.

The technical problem to be achieved by the present invention is to provide a static service combination method and system that can easily provide a new service using existing services through a service combination through the connection between the objects of the service provider area and the service user area. There is.

Another technical problem to be solved by the present invention is to execute a static service combination method on a computer that can easily provide a new service using existing services through a service combination through connection between objects of a service provider area and a service user area. The present invention provides a computer-readable recording medium having recorded thereon a program.

One embodiment of the static service combination method according to the present invention for achieving the above technical problem, receiving a request for a service provided from at least one or more service providers; Requesting each service provider to create a service session object through a service constructor object managing a connection relationship with at least one service provider; Receiving, through the service constructor object, interface reference information of each service session object created on each service provider side; And providing a service through a service session object created at each service provider based on the interface reference information.

Another embodiment of the static service combination method according to the present invention for achieving the above technical problem, in the method of combining a new service while providing a predetermined service through the already established access session and service session, receiving a service request step; Delivering the service request to a service provider providing a service corresponding to the service request through a service constructor managing a connection relationship with at least one service provider; Receiving interface reference information of a service session object created at the service provider side in response to the service request through the service constructor; Combining services of the service provider based on the interface reference information.

One embodiment of the static service combination system according to the present invention for achieving the above technical problem, manages the connection relationship with at least one service provider, to at least one service provider corresponding to the service combination request of the service user A service constructor for requesting creation of a service session object and receiving interface reference information of the generated service session object; A service configurator managing unit managing at least one service configurator and delivering the service combination request to a predetermined service configurator; And a session object unit generating a service session with the service session object based on the interface reference information and providing a service corresponding to the service combination request.

Thus, a new service combining existing services can be easily provided through the connection between the objects of the service provider area and the service user area.

Hereinafter, a method and system for combining static services according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating an embodiment of a service providing method using a static service combining method according to the present invention.

Referring to FIG. 1, user A 100 and user B 140 are provided with a combination of virtual conferencing 110 and video content 120 services.

The user A 100 and the user B 140 access the system 110 that provides the virtual conference service, create a virtual conference service session 115, and receive the virtual conference service. When the user A 100 or the user B 140 requests the video content service 125 of the virtual conference service, the virtual conference service system 110 that receives the video content service request receives the video content service system 120. Pass service request to Then, the video content service system 120 receives the video content from the system 130 storing the requested video content and provides the video content to the user.

The composition of the service combination is largely divided into the static service combination method and the dynamic service combination method. The dynamic service combining method is generally performed by a user's request. When a user requests a service combination online and the user's service objects recognize it, the newly created service session objects in the service provider area perform the service. to be. In contrast, the static service combination method according to the present invention requires a service combination by a service provider and a retailer, and provides a more economical service in which service providers create a new service using an existing service object. How to provide.

Therefore, the static service combination method according to the present invention emphasizes the application service provider's viewpoint rather than the user's request, and the service objects of the service constructors for the newly created service or the service constructor of the integrated application service object are managed. How to provide.

2A is a diagram illustrating a connection relationship between a service user and a static service object in a service provider area in the static service combination method according to the present invention.

Specifically, FIG. 2 illustrates a service object and a process in which a video conferencing (VCS) service provider 230 provides a service to a user using another VOD service provider 270 using a static service combination method. 2, there is a service user area 200 and two service provider areas 230 and 270. One of the service provider areas 230 and 270 serves as a broker 230.

Service combination refers to the creation of a new service or service object instance through a service component or a service composer. Therefore, to create a new application service, there must be an instance of the service objects corresponding to the new service. In order to perform a service combination, a service combination manager object 240 managing a service combination and a service composer object 250 operating a service object generated by the service combination are required.

The service constructor object 250 is similar to a provider agent object (hereinafter referred to as a 'PA') object that provides transparency to the interaction between the service user and the service provider. Establish a session and perform service provision management. Thus, important service management messages are delivered to the service session object via the service constructor object 250.

The service constructor object 250 manages a connection relationship with at least one service provider and allows a service user to establish a service session with the service provider. The service constructor object 250 divides service providers into predetermined groups in order to efficiently manage a plurality of service providers, and each service constructor object manages each service provider group.

The signaling method for providing a service in a service structure is called a session. A session is a temporary relationship between components assigned to provide a service for a certain period of time. A session can have several states during its lifetime, and hides the complexity of resource management and usage to present a simple perspective. Doing.

An access session is a relationship that exists between a service user and a service provider and is a session that must be established before the service user can use the service.

A service session shows information and functions related to performing, controlling and managing a service. A user service session and a number of users have a common function of showing the functions necessary for each user to hide the complexity of the service. It is divided into provider service sessions that provide the ability to use them.

The communication session functions to control the stream connection while providing an independent view of the resources required for the actual connection between the terminals.

For example, if a service user requests a combined service of virtual conferencing (hereinafter referred to as 'VCS') 230 and Video on Demand (VOD) 270, the service configurator managed object 240 requests the service request. Deliver to service constructor 250. The service user 200 may make a VoD service request while receiving the virtual conference service 250, 255, and may simultaneously request two services from the beginning.

Accordingly, the service constructor management object 240 transmits a service request to the service constructor object 250 that manages the connection relationship with the VCS service provider 230 and the VoD service provider 270. Referring to FIG. 2, since the VCS service provider 230 serves as an intermediary for service combinations, it is not necessary to request a separate service request from the service constructor object for providing a VCS service, and the VoD service through the service constructor object 250. The service request may be forwarded to the provider 270.

The VoD service provider 270 that receives the service request creates service session objects 280 and 285 for establishing a service session. As described above, the service session object includes a user service session object 280 and a provider service session object 285. The VoD service provider 270 delivers the interface reference information of the generated service session object to the service constructor object 250.

The service constructor object 250 provides the service user with service sessions 260 and 265 for the VoD service based on the received interface reference information.

2B is a diagram illustrating an embodiment of a static service combination system according to the present invention.

Referring to FIG. 2B, the static service combination system 291 is composed of a provider agent object unit 292, a service constructor manager 293, a service constructor 294, and a session object unit 295. The static service combination system 291 is connected to at least one service user 290 and service providers 296 and 297.

The provider agent object portion 292 initiates an access session with the service user 290 and receives a service combination request from the service user 290. The provider agent object unit 292 may receive a service combination request for providing another service while already providing a service.

The service constructor managing unit 293 forwards the service combination request received through the provider agent object unit 292 to the service constructor 294. The service constructor manager 293 manages at least one service constructor 294.

The service constructor 294 transfers the service request received from the service constructor manager 293 to the corresponding service provider 290. The service provider 290 creates a service session object in response to the service request, and delivers interface reference information of the generated service session object to the service constructor 294.

The session object unit 295 forms a service session with a service session object created at each service provider side 296 and 297 based on the interface reference information, and then provides the combined service to the service user 295.

3 is a diagram illustrating an embodiment of a static service combination attribute representation diagram according to the present invention.

Referring to FIG. 3, the attribute expression diagram 300 includes a service unique identifier (Svc_Name) 310, a service provider unique identifier (Svc_Provider) 320, a service factory interface reference (IR_of_SF) 330, and a maximum. The number of service users (Max_usr_Num) 340, a list of service names (Comp_Svc_Lst) 350, and a stream service request (Stream_Svc) 360 are included.

4 is a diagram illustrating an operation object configuration diagram of the static service combination method according to the present invention.

The functions that make up an open service are provided as a combination of one or more compute objects and compute object groups. The design and implementation of these open service operation objects has a service dependent characteristic. Therefore, a service operation modeling technique using a calculation object as a base unit cannot be applied to various services, which causes inconvenience and waste of new modeling for each service.

The service component is a basic unit of computational modeling designed to solve such problems in modeling of computational object units. An open service is composed of several objects that are in charge of accessing and providing a service. These objects perform service access and service provision between service users and services through mutual interfaces. A service component is a service construct that abstracts and abstracts the objects that make up a service by considering the commonalities of designs for a specific service.

 Service structure components are divided into access sessions, service sessions, and related object components according to the session concept.

As an access session component, a user application object (hereinafter referred to as 'UAP') is a component that directly interfaces with a service user.

The provider agent object (hereinafter referred to as 'PA') 402 transfers a message between the service users 400 and 410 and the service provider 420 and initiates an access session, at the request of the UAP 404. It requests the user's authentication to the service provider 420 and performs a function of transmitting and receiving a message related to establishing a service session and a invitation.

The initial agent object (hereinafter referred to as 'IA') 422 receives the user's ID and password to determine whether to establish an access relationship between the service user and the service provider, and at the request of the PA 402. A user agent object (UA) 424 for initializing an access session is performed.

The user agent object (hereinafter referred to as 'UA') 424 relays the service provider area with respect to all request contents of the service user transmitted through the access session, and serves the service user in the service provider area. It takes the place of the role of.

The service factory object (Service Factory, hereinafter referred to as SF) 432 is a session component, and performs a function of creating service session components for a service. The SF 432 creates a service creation request for a specific service and initializes one or more service components according to service characteristics.

The provider service session management object (Service Session Manager, hereinafter referred to as SSM) 436 is a service object that implements general session control and service specific control specific to a specific service in terms of the service provider 420. Supports the addition, invitation, and deletion of users through interworking with the associated UA 424.

The user service session manager object (hereinafter referred to as “USM”) 434 is a service object that implements session information and service characteristic control related to the service user 400. State management and support the various roles of service parties.

The service type manager (Service Type Manager, hereinafter referred to as 'STM') 430 is an object that stores and manages service-related information such as features and limitations of the service and an interface reference (IR) of the SF 432. It manages service provision type information for service combination with detailed functions and receives IR (Interface Reference) transmission request of SF 432 or SCF 438 from SubAgt (Subscription Agent) 428 for the requested service. Return the IR of the SF 432 or the SCF 438.

The service composer (SC) 440 is an object that operates a service object created by a combination of services. As a detailed function, the service composer (SC) 440 is responsible for the connection function between the respective areas when the service combination is performed. ) Transmits the IR of USM 434 to SCF 438.

The service composer factory object (hereinafter referred to as 'SCF') 438 is an object that creates and manages multiple SCs according to a service combination request of the SSM. The detailed functions of the SSM of each individual multimedia service object are as follows. And the IR of the USM to the SSM 436 of the new application composition service.

Specifically, FIG. 5 illustrates interaction of service objects corresponding to a part of forming a service combination session through the service constructor 588 based on the objects described with reference to FIG. 4. In particular, FIG. 5 illustrates a VoD service 594 during VCS service provision. Shows a detailed procedure of connection between operation objects of the static service combination method to combine the.

The service user 580 starts a service combination (S500). In other words, the service user 580 starts the service combination through the UAP (581). Then, the UAP 581 requests the service combination to the PA 582 (S505). At this time, the UAP 581 transfers ID, Password, and service-specific identifier (Svc_Name) information of the service user 580 to the PA 582.

The PA 582 requests the UA 583 to establish a service combination session (S510). The UA 583 requests the SF 584 to generate the USM 585 and SSM 586 for the service combination (S515). At this time, the SF 584 knows the interface reference information of the USM 585 and the SSM 586 (Initialize).

The SF 584 generates a USM 585 and an SSM 586 (S520). The generated SSM 586 requests the VF service from the SCF 587 (S587). The SCF 587 requests the VOD service to the SC 588 (S530). The SC 588 requests a VOD service session from the PA 589 of the VoD service provider side (S535). At this time, the SC 588 transfers the ID of the service combination provider to the PA 589.

The next five steps S540 to S560 are VOD service start procedures.

The PA 589 requests a service from the UA 590 (S540). The UA 590 requests the SF 591 to generate the SSM 592 and the USM 593 for the VOD (S545). The SF 591 generates the SSM 592 and the USM 593 (S550). The SF 591 transmits the addresses of the SSM 592 and the USM 593 to the UA 590 (S555). The UA 590 notifies the PA 589 of the creation of the service session (S560).

The PA 589 transmits interface reference information of the SSM 592 and the USM 593 to the SC 588 (S565). The SC 588 transfers interface reference information of the SSM 592 and the USM 593 to the SCF 587 (S570).

6 is a flow chart showing the flow of one embodiment of a static service combination method according to the present invention.

Referring to FIG. 6, the service constructor management object receives a combined service request from a service user (S600). The combination service request is a request for a combination of a new service among predetermined services as described above in FIG. 5 or a request of a combination of two or more services from the beginning.

If it is a service combination request for more than one service, the service constructor managed object delivers the combined service request to the service constructor. If the service constructor managing the connection with the service provider providing each service is different, the service constructor management object receives the combined service request from each service constructor. The service provider may simultaneously play the role of an intermediary that performs a combination of services, in which case it delivers the combined service request to other service providers only for services that are not provided by the broker.

The service constructor delivers the received combined service request to the corresponding service provider (S610). The service provider then creates a service session object for creating a service session. The service session object includes a user service session object and a provider service session object.

The service constructor obtains interface reference information of the service session object generated at the service provider (S620). The service constructor forms a service session between the service user and the service provider based on the interface reference information to provide a service (S630).

 The invention can also be embodied as computer readable code on a computer readable recording medium. The computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and may also be implemented in the form of a carrier wave (for example, transmission over the Internet).
