The present invention relates to a retailer service method in a multi-communication service providing system, and more particularly, to a retailer service method for an open information communication network based service broker in various multi-communication service providing systems.

Developed countries are focusing on building their own information highways and application software to take the world leadership in the information society. As the international market changes and technology advances every day, it is predicted that multimedia services incorporating information such as video and audio will be the mainstream, and researches on the development of such services are being actively conducted at home and abroad. .

In addition, due to the spread of the Internet, human beings can receive or use desired information anytime, anywhere. In particular, the high-speed information network technology has enabled high-speed data transmission, and accordingly, various multimedia services such as video conferencing service and video on demand (VOD) have been provided or studied through the high-speed communication network.

In line with this trend, operators' investments and efforts for the provision of new services quickly and the effective maintenance of communication networks are increasing day by day. However, these efforts are performed independently by each service provider, and thus not only do not ensure structural homogeneity, but also the service structure provided in the same service provider area is not the same.

Such a structural difference has a problem in that the development of new services does not facilitate the unmodified recycling of existing components. Therefore, in order to facilitate the rapid development of new services by improving the reusability of components, 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 demand for high-performance services of the user, a standardized standard for a retailer (service broker) service function that allows each service function to be combined with each other should be prepared.

The retailer service provides the service to the service user by providing the service to the service user or by accessing a third party service provider. The requirements of the retailer service are to register and terminate service users using various services, to register and terminate service providers who want to provide various services, and to use services of service users.

Research on open service structures and retail services is carried out by various domestic and international research institutes and organizations, and the Telecommunication Information Networking Architecture-Consortium (TINA-C) (hereinafter simply referred to as "TINA-C") is the most active group. Is one of.
The research groups undertaken in connection with TINA include several project groups, including VITAL and ReTINA, each of which contains dozens or dozens of companies and research institutions. Among these groups, researches related to retailer services for service intermediation include Tina Open Service Creation Architeture (TOSCA), Service Creation Engineering Environment (SCREEN) and Service Creation in an Object-oriented Reuse Environment (SCORE). These groups are currently conducting researches on the extension of service functions through the combination of service functions and platform development to facilitate the development of new services. Looking at the research carried out by the group so far, the design and verification of the computer-aided software engineering (CASE) tool for the development of new services has been partially carried out, so that it can be used for the development of various services. The research on the supplementation of the tool for the future seems to be carried out.

TINA-C presents a software hierarchical structure for the various functions provided on the network. The service structure proposed by TINA-C is provided by service objects that interact in a distributed processing environment. Thus, the service structure defines how components are bundled and interact with components, which are combinations of service objects needed to create a service.

This service structure reflects the requirements for the retailer service functions, and the retailer service concept and functions are defined in the defined service structure. However, there is a problem in that the defined retailer service concept or functions are not detailed enough for practical service development.

Therefore, in order to specify the retailer service function, detailed standardization of the interface and connection procedure between components constituting the service is required.

The present invention has been proposed to meet the above-described requirements, and provides detailed standardization of the interface and connection procedure between components constituting a retailer service for an open information communication network based service intermediary in various multi-communication service providing systems. The purpose of the present invention is to provide a retailer service method in a multi-communication service providing system so that a new service can be easily configured.

The method of the present invention for achieving the above object is a retailer service (Retailer Service) method applied to a multi-communication service providing system, the service that enables a retailer service in response to a request of a user terminal the first service provider (Provider 1) A service list providing step of providing a list; When the first service provider receives a request for a retailer service from a user terminal provided with the service list, using the retailer service environment information, the first service provider determines whether the requested retailer service is available in the user terminal. Checking service availability; And after confirming the availability of the service, after accepting a retailer service request of the user terminal only when the requested retailer service is available in the user terminal, between the first service provider and the second service provider. A retailer service providing step of providing a retailer service to the user terminal by setting up a retailer service session and exchanging session information; and upon requesting termination of the retailer service, releases the retailer service session set in the retailer service providing step. It further comprises a retailer release step.
On the other hand, the present invention is a retailer service (Retailer Service) method applied to a multi-communication service providing system, the first service provider (Provider 1) provides a service list that provides a list of services available for retailer service at the request of the user terminal step; When the first service provider receives a request for any retailer service from the user terminal provided with the service list, whether or not the requested retailer service is available in the user terminal is used using retailer service environment information. Confirming service availability checking step; As a result of the checking in the service availability checking step, the first service provider accepts a retailer service request of the user terminal only after the requested retailer service is available in the user terminal, and then the requested retailer service. Service type determination step of determining the type of; As a result of the determination in the service type determination step, if the requested retailer service is a federation type, a feather for establishing a federation service session between the first service provider and the second service provider and exchanging respective session information Migration step; And a composition for establishing a composition service session between the first service provider and the second service provider and exchanging respective session information if the requested retailer service is in a composition form as a result of the determination in the service type determination step. Steps. In addition, the present invention, the termination service type determination step of determining the type of the re-requested retailer service in accordance with the request to cancel the retailer service; A federation release step of releasing the federation service session established in the federation step if the termination service retailer is in a federation form as a result of the determination of the termination service type determination step; And a composition releasing step of releasing the composition service session set in the composition step if the canceled retailer service is a composition form as a result of the determination of the termination service type determination step.
The research contents of most research groups that are currently conducting research on the structure of the next generation communication network include the study on the definition of the service structure to facilitate the service development and management. At present, TINA-C proposes the basic framework of the service structure, and is proceeding with detailed standardization based on the framework. The service structure proposed by TINA-C defines a retailer service as one of the ways to easily expand new service functions. However, the definition of retailers is also a framework only, and some small groups are conducting research for detailed standardization.

Accordingly, the present invention is to easily configure a new service through a detailed standardization of the interface and the connection procedure between the components constituting the service and research of the retailer technology for the service intermediary based on the open information communication network structure in various multi-communication service environment.
In other words, the present invention defines a function extension of existing service objects and an information flow between objects in a service design process for a retailer service, and defines a connection between a new retailer service object and a related object, thereby reusing the existing designed service objects. It suggests the possibility of creating a new application service.

In addition, the present invention proposes a retailer service configuration method in various open multi-communication service environment.

The signaling method for providing a service in a service structure is called a session. A session refers to a temporary relationship between components assigned to provide a service for a certain period of time. A session can have various states during its lifecycle, and provides a simple perspective by hiding the complexity of resource management and usage. .

Sessions presented by TINA are divided into access session, service session and communication session.

Here, the access session is a session that must exist before the service user uses the service because it exists between the service user and the service provider.

The service session shows the information and functions related to performing, controlling and managing the service. The service session can be used by several users and the user service session which functions to hide the complexity of the service to the user who shows only the functions necessary for each user. The sessions are divided into provider service sessions that represent their capabilities.

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.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, a preferred embodiment according to the present invention will be described in detail with reference to FIGS. 1A to 5. That is, the retailer service configuration method for service brokering based on open information communication network structure in various multi communication service environments will be described in detail.

4 is a flowchart illustrating an example of a retailer service method according to an embodiment of the present invention, and illustrates an information flow between arithmetic objects for session establishment through federation and composition.

As illustrated in FIG. 4, as_UAP1 201 requests a list of services that can be federated and composed from the PA1 202 (401). PA1 202 requests UA1 205 for a list of services. UA1 205 requests a list of services from Sub1 206. Sub1 206 returns a list of services to UA1 205. UA1 205 returns a list of services to PA1 202. PA1 202 returns a list of services to as_UAP1 201.

Subsequently, as_UAP1 201 forwards the service federation and composition request to PA1 202 (402). PA1 202 then forwards the federation and composition request to UA1 205.

The UA1 205 requests the federation and composition service environment information from the Sub1 206 (403). Sub1 206 returns service usage environment information to UA1205.

UA1 205 compares the current terminal and the service usage environment. In other words, it is determined whether the user terminal can use the federation and composition service using the service usage environment information (404).

As a result of the determination of "404", if the service is available, the federation and composition request is accepted (405). That is, UA1 205 forwards the federation and composition request to SSM1 210 (405). On the other hand, if the service is unavailable, the federation and composition will be terminated (412).
If the service is available. Subsequent processes are divided into two according to the type of retailer service requested (406).

First, in the case of federation, the SSM1 210 is federated by requesting the federation from the PeerA 208 and the PeerUSM 212 (407, 408, 409, 413). The service provider domain (eg, Provider Domain 2 in FIG. 2) is performed in the same manner as the above procedure (407, 408, 409, 413).
That is, by creating a federation agent and a federation USM in each service provider domain (407), by using it to establish (set up) a federation service session between the two service provider domains (408) by exchanging session information (409). The federation service is provided to a user terminal.

Second, in the case of a composition, the composition is made by requesting federation from SSM1 210 to CompA and CompUSM (410, 411, 409, 413).
In the service provider domain, a composition agent and a composition USM are created (407), and a composition service session is established (established) between the two service provider domains using the service provider domain (411), thereby exchanging session information (409). To provide composition services.
As can be seen from FIG. 2A and FIG. 2B, it is obvious that the federation service and the composition service may be independently performed.

FIG. 5 is a detailed flowchart of an embodiment of a retailer service canceling method according to the present invention.

As shown in FIG. 5, ssUAP2 sends USM2 a service federation and composition termination request 501 and a notification 502. By doing so, the relationship between the two sessions is terminated (503).

USM2 requests SSM2 to terminate the session. SSM2 sends USM2 a session termination request and notification. USM2 requests ssUAP2 for session termination and notification. Shut down ssUAP2.

In this case, if the retailer service type is a federation session type (504), the federation session is terminated (505) and the federation agent and USM are deleted (506).

If the retailer service type is a composition type (504), the composition service session is terminated (507) and the composition agent and the USM are deleted (508).
The method of the present invention as described above may be implemented as a program and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.). Since this process can be easily implemented by those skilled in the art will not be described in more detail.
The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

The present invention as described above has an excellent effect of effectively operating the retailer service through each object composed of object components on a distributed environment (DPE).

That is, the present invention proposes a retailer service configuration method for service mediation based on an open information communication network structure in various multi-communication service environments, thereby establishing a retailer service manager object function and defining a detailed service operation object for a retailer service and a mutual object. Access, information sharing procedure for accessing and retailer service between different distributed environments, retailer service connection method and interface, service object management plan for retailer, retailer service function provision scenario presentation, retailer service There is an excellent effect to establish an algorithm.
