Description

Interface method between mobile communication system and content provider server {Method for Interface Between Mobile Communication System and Contents Provider}

The present invention relates to a communication method between a mobile communication system and a content provider server, and more particularly, to an interface method between a mobile communication system and a content provider server based on a simple object access protocol (SOAP), which is a web service technology element. It is about.

As the use of wireless Internet is becoming more common, various wireless Internet services have been provided. The wireless Internet service may be produced and serviced by a mobile communication system provider or may be produced and serviced by an operator independent of the mobile communication provider, and a mobile operator and an independent operator are generally referred to as a content provider.

At present, in order to provide a wireless Internet service produced by a content provider, it must be interworked with a platform of a mobile communication system for providing a service, and an interface specification for this is required. To this end, the mobile communication system creates a unique interface specification whenever a new service (content) is developed (or whenever a service development is needed), distributes it to a content provider, and then develops a service conforming to the standard. To work with

However, the current interface between the content provider server and the mobile communication system platform has a disadvantage in that it cannot be extended for a new service. Therefore, if the same content provider needs to interwork with the platform of the same mobile communication system for different purposes, the existing interface cannot be used and a new interface standard must be developed.

As a result, every time a content provider develops a new service, a new interface specification must be distributed and the service must be developed accordingly. Therefore, the cost and time required for service development are increased, and the service cannot be released in a timely manner. have.

The present invention has been made to solve the above problems, by introducing an interface method that can be flexibly connected to the platform of the mobile communication system and the content provider server can reduce the time and cost required for service development The technical challenge is to present the interface method.

The present invention for achieving the above technical problem is a plurality of platforms for providing a wireless Internet service to the mobile communication terminal, a platform register and content provider server for storing and managing information related to the wireless Internet service provided through the platform and the platform An interface method between a mobile communication system including a content broker serving as a gateway between a content provider and a content provider, wherein the platform defines a SOAP-based interface and classifies message descriptors required to use each interface by service type. Storing in the platform register; After the content provider server checks the type of the interface registered in the platform register, selects one of the SOAP-based interfaces registered in the platform register, composes a service request message, and sends the service request message to the platform broker. A platform broker performing service logic according to the service request message; And transmitting, by the platform broker, a service logic execution result to the content provider server.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a conceptual diagram illustrating a relationship between a mobile communication system and a content provider server according to the present invention.

The mobile communication system includes a platform 10-1 to 10-n for providing various services to a mobile communication terminal, and a platform register for managing various information about services provided through the platforms 10-1 to 10-n. And the platform broker 30 serving as a gateway between the content provider servers 40-1 to 40-m and the platforms 10-1 to 10-n. In addition, the content provider server (40-1 ~ 40-m) it is preferable to precede the process of registering as an affiliate in the mobile communication system to provide a service through the mobile communication system.

In the present invention, an application program interface (API) based on SOAP, which is an international standard transport protocol, is used to facilitate interworking between a mobile communication system and a content provider server. SOAP is an XML-based web service technology element for supporting data exchange between client and server. Detailed descriptions of SOAP-based interfaces are provided through the Web Service Description Language, a kind of XML. SOAP has protocol independence, language independence, platform and operating system independence, and is easily extensible because it is written in XML.

Therefore, using a SOAP-based interface that conforms to the XML grammar makes it easy to extend the service field, reducing the cost and time required to build the interface required for new services. In addition, the SOAP protocol is free, which further reduces costs. It can be increased.

2 is a flowchart illustrating an interface method of a mobile communication system and a content provider server according to the present invention.

The platform of mobile communication system (10-1 ~ 10-n) defines the interface based on SOAP, and classifies the message descriptor (API name, NS, data type, etc.) required to use each interface by service type. Stored in the register 20 (S101). Here, the message descriptor is generated in compliance with the WSDL grammar.

In order to use the interface provided by the platform, the content provider server (40-1 ~ 40-m) must perform the process of registering as an affiliate and authenticated on the platform (S102), the interface registered in the platform register 20 Check the type of (S103).

In addition, the content provider servers 40-1 to 40-m select one of the SOAP-based interfaces registered in the platform register 20, modify the service field if necessary, and construct a service request message (S104). ), And transmits it to the platform broker 30 to request a service (S105).

Upon receiving the service request, the platform broker 30 performs the corresponding service logic (S106), and transmits the result to the content provider servers 40-1 to 40-m (S107). In this case, the platform broker 30 may perform a process for handling an exceptional situation.

3 is a diagram illustrating a construction environment of a complex composite service providing system.

The complex service providing system 100 was developed to provide future integrated services between the information, communication, and broadcasting industries. The complex service providing system 100 combines each function necessary to provide a wireless Internet service with a platform service capability feature (PSCF). It is a system that allows to create a composite service by using, and provide it through the composite service provider server.

As shown in FIG. 3, the complex service providing system 100 interoperates with an application service platform 200, a customer management system 300, a mobile communication system 400, and a complex service provider server 500, and has a unit function. It manages information and information, and allows a complex service developer to easily create a complex service 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.

FIG. 4 is a detailed configuration diagram of the complex service providing system illustrated in FIG. 3. The framework unit 110 is responsible for authentication, authority, registration, etc. necessary for providing a complex service, and supports interworking with an application service platform. , A state management unit 120 for integrating and managing various service data and customer data, and allowing a customer to view and change his or her favorite information, and a complex service production unit 130 for supporting a complex service developer to develop a complex service. do.

The framework unit 110 is responsible for authentication, authority, registration, and subscription functions for the complex service provider server 500 required for producing a complex service, and registers and changes each unit function in connection with the application service platform 200. , Delete, and store and manage various control information such as unit function related information, complex service provider server related information, and complex service related information. It also has a workflow management function that automates and effectively manages the combination of unit functions to form a specific composite service.

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. Here, the status information may include customer identification value, group, mobility information (location, power status, etc.), qualification information (terminal information, etc.), personal information (location information disclosure, short message reception, personal information disclosure, etc.). ), Symbolic information (interests, access lists, etc.) and is stored in the control information repository. In addition, when the state information is changed in the application service platform, the application service platform should reflect this to the state manager 120 in real time.

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.

As services through the wireless Internet are diversified, as described above, there is a strong demand for the development of a complex service implemented by a combination of unit functions, and the server for providing the complex service providing system and the complex service (500). ), There is a need for a guaranteed interface for connection with the application service platform 200 including the unit functionality.

5 is a diagram illustrating a case where the interface method according to the present invention is applied to a complex service providing system.

The API adapter of the framework unit 110 and the composite service provider server 500 are connected using an open API, and the API adapter of the framework unit 110 and the application service platform 200 may be a middleware API, an open API, or an existing API. Can be accessed by the API. The middleware API method is a method of wrapping and delivering an open API to a middleware-based API when the application service platform 200 provides the middleware API, and the SOAP-based open API method is a SOAP application protocol platform. When providing an open API based on, the API adapter transfers a request to the application service platform 200 as it is, and the method of using an existing API uses the API used by the existing application service platform 200 as it is. In this case, the API adapter simply provides a wrapper.

As such, by using a SOAP-based interface for accessing a content provider server and a mobile communication system for providing a content or complex service, the interface specification can be extended only by changing a field of an XML document. It is possible to provide various services without defining them.
