In general, wireless Internet services do not provide only one service, but various services are provided in a complex form. For example, in case of location-based services, location-based services should be provided as a main service and provide authentication and settlement functions while providing additional mobile commerce and messaging services. In the case of mobile commerce and messaging services, user authentication and settlement functions should be provided. Must be provided.

As such, at present, functions such as authentication and settlement required to provide one service are separately constructed because the interface interworking structure between the respective application programs is different. This leads to redundant application development and higher costs.

On the other hand, user demand for wireless Internet service is sensitive to the trend and diversified, and in particular, the demand for personalized service is increasing. In addition, as the industries such as information, communication, and broadcasting are gradually integrated, an environment capable of providing various and high value-added services is being formed, and a platform for this is required. Providing differentiated new services based on the current platform has to address challenges such as market timeliness and load on commercial platforms.

By the way, the platform that provides the wireless Internet service currently provides the internal / external interface standard suitable for each service scenario, but it is not standardized and uses different protocols and messages for each service. However, it is difficult to develop a new concept of service that combines unit functions.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and manages each function required to provide a wireless Internet service as a unit function, simplifies the dependencies inside and outside the platform, and simplifies and standardizes the internal and external services.

The complex service providing system 10 according to the present invention has been developed to provide future integrated services between the information, communication, and broadcasting industries. In this sense, the complex service providing system 10 may be defined as a next generation convergence platform (NGcP). Hereinafter, each function required to provide a wireless Internet service will be referred to as a Platform Service Capability Feature (PSCF), and this unit function is configured in an open API format, which is an open application program interface.

Here, the open API refers to a standard interface that is compatible with international standard specifications that composite services use to use unit functions and information of an application service platform. Open API should be designed using XML and should be designed to be scalable in consideration of services to be supported in the future. The protocol that transmits API should basically support SOAP in consideration of the introduction of web service in the future, and other transport protocols conforming to international standards can be applied. Simple Object Access Protocol (SOAP) refers to a text-based and XML-based protocol for exchanging information for distributed objects in a distributed environment. SOAP uses low-level protocols such as IP or HTTP, but the application decides which high-level protocol to use between a particular client and a particular server. There are several ways to specify these protocols, but using Web Service Description Language (WSDL) is the most useful.

The API category required in the complex service providing system of the present invention includes an API set for authentication, authorization, registration, and subscription, an API set for obtaining control information, an API set for obtaining status information, and a composite service for producing.

It allows service providers to easily create complex services using unit functions. Here, the composite service means a service generated by combining a plurality of unit functions and information, and does not mean a combination or bundle of information (content) itself, but a combination of unit functions constituting services of different categories. Means another type of service that is created by In addition, the composite service provider may be a mobile network operator or a content provider independent of the mobile network operator.

The composite service generated by the composite service providing system 10 is configured by using various functions and data provided by the application service platform 20, and the application service platform 20 is a composite service providing system 10. You can request registration, change or deletion. Various information (customer, terminal, service profile, etc.) and subscriber mobility information (Presence information) possessed by the application service platform 20 are integrated and managed as status information in the composite service providing system 10 (Presence and Availability Management (PAM). When the information of the application service platform 20 is changed, the complex service providing system 10 should update the stored state information to reflect the changed information.

The composite service providing system 10 may request a unit function to the application service platform 20 according to a request of the composite service provider server 50, and the request is transmitted by an open API method, which is an open service interface. . To this end, the complex service providing system 10 analyzes the request of the complex service provider server 50, changes the request message into a request message that can be accommodated by the application service platform 20, and delivers the request message. In addition, the composite service provider server 50 may request various state information to the composite service providing system 10, and in some cases, the composite service providing system 10 may apply such a request to the application service platform 20 in accordance with an open API. To pass. In addition, when the state information stored in the complex service providing system 10 is changed, the complex service providing system transmits it to the application service platform 20 to reflect the changed state information.

The customer management system 30 is a system for managing basic information and additional information of a mobile communication service subscriber, and the customer, terminal, service profile information, and mobility information of the customer management system 30 are combined in the complex service providing system 10. Integrated management with status information. In addition, when the customer information is changed in the customer management system 30, it is transmitted to the complex service providing system 10 so that the change information is reflected in the state information.

When the composite service provider server 50 requests status information in an open API format, the composite service providing system 10 may request status information from the customer management system 30 in some cases. In addition, when the state information managed in the complex service providing system 10 is changed, it is transmitted to the customer management system 30 to reflect the change information.

The composite service provider server 50 may utilize a specific function provided by the mobile communication system 40, which is referred to as a network unit function (NSCF) separately from the unit function (PSCF). The composite service provider server 50 may request the composite service providing system 10 to register, change, or delete a network unit function. The composite service providing system 10 manages various customer, terminal, service profile information, and mobility information that can be provided by the mobile communication system 40 as state information. In addition, when the customer information managed by the mobile communication system 40 is changed, the composite service providing system 10 reflects this to update the status information.

When the complex service provider server 50 requests a network unit function in an open API format, the complex service providing system 10 changes the information into a request message in a form that can be accommodated in the mobile communication system 40, thereby providing a mobile communication system ( 40). In addition, when the composite service provider server 50 requests status information in an open API format, the composite service providing system 10 may transfer the request to the mobile communication system 40 in some cases.

Meanwhile, the complex service provider server 50 utilizes various unit functions and state information by using an open API, and must have a proper authority for this. To this end, the composite service provider server 50 may request an application, change, or deletion of authority from the composite service providing system 10. In addition, when the composite service provider server 50 requests unit function and status information, the composite service providing system 10 must precede authority verification for the composite service provider server 50.

The unit function related information includes the descriptor of the unit function (creator, creation / modification date, category information, etc.), the system information (system name, IP, OS, etc.) that registered / modified / deleted the unit function, the complex service using the unit function. List, category descriptor (unit function list, creation / modification date, etc.), category-specific usage authority information, and unit function list.

In addition, the complex service provider server-related information includes a descriptor (company name / department name, contact person, contact information, etc.), the list of complex services registered by the provider, the group information of the provider (authority information), and the provider list. It includes service descriptor (creator, creation / modification date, etc.), unit function list, provider information that registered composite service, and composite service list.

Next, the framework unit 110 has an interface environment that is easy to use and a notification function when an event occurs so that an administrator can easily handle a complex service related request. Using the framework management function, the framework manager can handle the subscription request of the composite service provider server, handle the unit function use request, handle the registration / change / delete request of the unit function, and handle the version management and exception handling according to the unit function change / delete Do this. When changing / deleting a unit function, the process of checking whether there is a composite service using the unit function must be preceded, and changing / deleting is possible only when there is no compound service using the unit function. Do. If there is a composite service using the unit function requested for change / delete, rejecting such a request also becomes a role of the framework manager. In addition, the administrator may forcibly change / delete the unit function.

For a guaranteed connection between the composite service providing system 10, the composite service provider server 50, and the application service platform 20, the framework unit 110 may support various connection schemes, which are illustrated in FIG. 4. .

Can be. The middleware API method is a method of wrapping and delivering an open API to a middleware-based API when the application service platform 20 provides the middleware API, and the SOAP-based open API method is an application service platform 20 SOAP. When providing an open API based on, the API adapter transfers a request to the application service platform 20 as it is, and the method of using an existing API uses the API used by the existing application service platform 20 as it is. In this case, the API adapter simply provides a wrapper.

State management unit 120

Next, the state manager 120 of the complex service providing system 10 of the present invention will be described. The state management unit 120 manages various service data and customer data interspersed in the mobile communication system as status information (Presence and Availability Management (PAM)), and allows customers to inquire and change their information. Includes collection and analysis, control information storage, and event management.

Status information includes customer identity, group, mobility information (location, power status, etc.), entitlement information (terminal information, etc.), personal information (whether location information disclosure, short message reception, personal information disclosure, etc.), symbol Contains information (interests, access lists, etc.) and is stored in the control information repository.

The complex service provider server 50 may use state information managed by the state manager 120. In this case, the framework unit 110 inquires the state manager 120 and provides the result, which is illustrated in FIG. 5. Shown in

The method (2) uses state information through an existing system, wherein the composite service provider server 50 requests the state information from an existing system such as a location based service system (LBS), a mobile commerce system, a multimedia messaging system (2 -1), the existing system queries the state manager 120 to obtain information (2-2) and transmits the information to the composite service provider server. In addition, the method (3) represents a case where the composite service provider server 50 directly queries the state manager 120 to obtain desired state information.

On the other hand, when the state information is changed in the individual application service platform, the application service platform should reflect this in real time to the state management unit 120. The data collection and analysis functions of the state management unit 120 will be described as follows. same.

6 is a view for explaining a data collection method in a complex service providing system according to the present invention. As shown, when the database managed by each layer (service layer, application layer, access layer, service management layer) of the application service platform is changed, the changed information is transmitted to the message processing unit 100 through the interface adapter, The message processor transmits the transmitted message to the state manager 120 using a queue method.

In addition, even if the information managed by the head management system 30 is changed to pass it to the state management unit 120 through the message processing unit so that the changed information can be reflected in real time.

Next, the event management function of the state manager 120 will be described. The event management function refers to a function of notifying the complex service using the changed state information when the state information change occurs. To this end, the composite service provider server may register the type of event to be notified in the state manager 120, and notify the corresponding composite service provider server when a registered event occurs.

Complex service production unit (130)

The composite service production unit 130 includes an editing function, a simulation function, a testing function, and a service request / management / analysis function necessary to support a complex service developer to easily develop and commercialize a complex service and a workflow.

The composite service developer designs a service by checking a list of unit functions available through the composite service production unit 130 and collecting unit functions in a drag / drop manner. After that, the collected unit functions are accumulated to create a new complex service, and the developed complex service is tested in the same environment as the actual commercial environment.

In addition, if there is a service request for a complex service that has been developed and tested, it is determined whether to approve it. If there is a problem in the test result, the service request may be impossible to implement.

When the service request is approved and the service is started, it continuously manages the complex service such as checking statistics and service abnormalities, and provides the tool to analyze the service type. Presentation to improve and adjust the service.

In the above, the composite service providing system 10 according to the present invention has been described. The composite service providing system 10 interworks with the application service platform 20 as described above, and the application service platform includes various layers and a plurality of unit functions, and each unit function is executed in the unit platform (see FIG. 3). ).

As shown, it can be seen that the service layer, the application layer, the access layer, and the service management layer of the application service platform each have a plurality of unit platforms, and each unit platform is connected through a middleware adapter.

Interworking between each layer should be interworked with loosely coupled middleware to ensure independence as much as possible, and interworking between modules within the layer is also flexibly combined. However, components inside the module are tightly coupled with each other, so they need tightly coupled middleware integration.

In order to integrate the platform based on middleware, it is necessary to guarantee the messaging performance close to the data transmission speed between systems, to simplify the existing interworking interface as much as possible, and to reuse the load without deleting the transmitted message once. It is desirable to design so that it can be reduced.

In addition, it is possible to modularize and use the required unit functions for the designated system in the application layer and the service management layer. For this purpose, the external interface, the access point, and the internal business logic must be independently constructed.

As such, interworking between application service platforms required for complex service development is implemented using an open API in the same manner, and a complex service developer can query a desired API through a framework of the complex service providing system. In addition, by utilizing the workflow function, it is possible to reuse not only the unit functions provided by the application service platform but also a combination of the developed unit functions. In addition, the service data can be used in the same way as the unit function can be used in the same form using the open API.

Those skilled in the art to which the present invention described above belongs will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential features. Therefore, the above-described embodiments are to be understood as illustrative in all respects and not as restrictive. The scope of the present invention is shown by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.

As described above, the present invention can quickly and easily implement a complex service by combining unit functions, which are repetitive and core service functions required for providing a wireless Internet service, and recycle a combination of unit functions by using a workflow management function. Service can be implemented to minimize the cost of service development and ensure the stability of service provision.

In addition, it is possible to generate added value by integrated management and analysis of distributed service-related information and personal information, through which it can be used for various interpersonal services.
