Description

Apparatus and method for extended markup language based service customization in an intelligent network}

The present invention relates to an intelligent network service ordering apparatus and method using XML, and more particularly, to an apparatus and method for an intelligent network service subscriber expressing his service in XML (eXtended Markup Language) and graph in an intelligent network.

In general, the intelligent network includes an SSP 10 for processing basic calls, a Service Control Point (SCP) 20 for controlling an intelligent network service, and an IP (Intelligent Peripheral) for supporting a client access to a service. (11), a service management system (SMS) 40 for managing service data, and a web browser 70 for ordering an intelligent network service through the Internet.

When the customer orders the service through the web browser 70 and the SMS 40 operated by the service provider, the service order information is downloaded to the SCP 20 through the SMS 40 so that the customer can use the service.

In an intelligent network, a service order allows a customer to design and manipulate his or her own service, adding to the SCP 20 their own logic that controls the behavior of each of the network elements, such as the SSP 10 and the IP 11. will be.

In order for such a service order to be possible, a means of quickly designing, developing and deploying a service has emerged as an important factor. The flexible service logic (FSL) concept described in Belcoa's GR1280 Recommendation provides a means to control supplementary services through data. Here, the SLP (Service Logic Program), which is a logic mounted on the SCP 20 to control a service, is composed of a part that a service executes in common and an FSL that controls a service order logic specific to a customer. In FSL, the decision tree is used to construct the message processing logic. Such logic may be specifically defined for the contractor himself or herself who subscribes to the service, or may be common to the contractor and specific to the service.

The decision tree consists of interconnected decision, action, and assignment primitives. These decisions and actions are organized into a directed acyclic graph (DAG) and represent the customized service desired by the service contractor. In these customized services, control begins at a single root node and each node can have multiple outputs depending on the decisions or actions on that node.

Currently, the ordering method for most intelligent network services is to connect to the customer service center of the telecommunication service provider by telephone, or to transfer the desired service data to the web browser by HTML (Hypertext Transfer Markup Language) method when using the Internet. Taking a way to order.

However, when using the service order method using the Internet, there is a problem in that it is not possible to create a dynamic web document due to the characteristics of HTML, there is no extensibility to add a tag suitable for a service order environment, and a tag that is unique according to a company that provides a web browser. The problem is that it is not standardized by support.

Accordingly, when a new intelligent network service is developed to allow a customer to operate his or her own service through the Internet, the customer service data is converted into a string according to the existing tag, delivered to the web browser of the customer, and displayed on the screen, where the customer inputs data. After converting it to the existing tag and delivering it to SMS and SCP, it is reflected in service control.

In particular, when the service data structure is changed, the code itself that implements the verification rule for the service data must be changed, and it is not scalable because service data cannot be represented by the structural method.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, the intelligent network service ordering device by XML to express the customer order service using the XML so that all the order content desired by the customer in one document And to provide a method.

In addition, another object of the present invention is to specify the rules that the service data should have in the Document Type Declaration (DTD) of the service order document, and determine whether the inputted customer data is valid or set by the XML processor for intelligent network service verification. It is to provide the intelligent network service ordering device and method by XML that can be checked in the contractor's own web browser.

In order to achieve the above objects, an intelligent network service ordering device based on XML according to a preferred embodiment of the present invention includes a service management system for managing service data, and a web browser for accessing the service management system through the Internet to order the intelligent network service. And, an intelligent network service ordering device in an intelligent network having a service control system for controlling the intelligent network service.

The web browser is a service graph editor for expressing service control logic desired by a customer, a service graph-XML interpreter for converting a service graph edited from the service graph editor into XML, and communication management for communication with the service management system. With means,

The service management system is a service order manager for managing a service order in the service management system while communicating with the communication management means, an XML-FSL interpreter for converting service XML data received from the web browser into an FSL, required for service orders. And a metadata manager for managing GUI information and an SMS FSL converter for controlling the download of the converted FSL data to the service control system.

The intelligent network service ordering method using XML according to an embodiment of the present invention includes a service management system for managing service data, a web browser accessing the service management system through the Internet, and ordering an intelligent network service, and the intelligent network service. An intelligent network service ordering method in an intelligent network having a service control system for controlling the same,

2 is a schematic representation of an intelligent network service ordering device based on XML according to an embodiment of the present invention.

The device is a service graph editor 44 for expressing service control logic desired by a customer, a service graph-XML interpreter 47 for converting an edited service graph into XML, and an SMS communication manager 45 for communicating with SMS. A web browser 49 of the customer side provided with; A service order manager 48 for managing a service order at a service management system (SMS) side while communicating with the web browser 49, and an XML-FSL for converting service XML data received from the web browser 49 into FSL. A service management system having an interpreter 41, a metadata manager 43 for managing GUI information required for service orders, and an SMS FSL converter 46 for controlling the download of the converted FSL data into a service control system (SCP). It consists of 51.

The XML-FSL interpreter 41 determines whether the order of determination and call processing in the decision tree is correctly described in the service order data, or whether an incoming call number used for the service is correctly input. The call processing describes the rules for how a call should be handled under a given condition. These rules are expressed in the decision criteria and call processing generated when the service is created. The FSL interpreter on the SCP can interpret this decision graph, where control logic for all contractor order services is stored as data at the decision, action, or assignment node.

Service Logic Program (SLP) in SCP can execute actions stored in each node on this FSL and has a decision graph search function to address the need for logic stored in decision graphs on specific points in customized services specified by the customer. It can be decided to provide the service desired by the customer.

Using XML, the web browser 70 can graphically represent individual nodes and node connections by identifying decision conditions and call processing. There is an XML tag that opens and closes, so that a script representing the entire call processing can be included in this XML, as well as indicating where to execute it. Each node and its output are both represented as XML tags, and parameters are represented by tag attributes. Most node tags have output tags and represent below the decision tree.

The decision tree data on the service management system 51 instructs the service logic on the SCP what to do next.

3A and 3B are XML representations of UPT (Universal Personal Communication Service), which is an intelligent network service according to an embodiment of the present invention. PCDATA represents analyzed character data or text, and the * symbol indicates that an item can be repeated. Because XML is freeform, it depends on how you interpret it. Your web browser won't know what to do even if you read this document. This part is executed by the service graph-XML interpreter downloaded from the intelligent network service management system (SMS) and displayed on the screen.

4 is an example of FSL expression for a time-based routing function of an intelligent network service according to an embodiment of the present invention. If node 0 (203) is a weekday (Mon..Fri), node 1 (205), otherwise proceeds to node 3. Node 1 determines time zone again and proceeds to node 2 if 09: 00-18: 00 and connects to 025266134, otherwise proceeds to node 3 and dials 03312212233.

5 is a metadata structure diagram of a metadata manager employed in an embodiment of the present invention. The metadata manager 43 has information about the GUI required for the service order. The GUI information on the DB is interpreted by the service graph-XML interpreter, converted into HTML, and displayed on the web browser. The service ordering session 113 represents an ordering program of a service currently in operation, and the service ordering GUI 111 includes a menu 103 and a form 105. Form 105 again consists of fields 107 and 109, and service order rule 101 validates upon entry of service order data.

6 is a diagram illustrating an intelligent network service order screen employed in an embodiment of the present invention. In the service order form in the window, when the customer clicks the intelligent network service order part in the system menu, the corresponding javascript is activated to call the SMS communication manager 307 Java applet, find the XML metadata corresponding to the UPT GUI, and then use the service order form. Generate HTML

When the customer edits the service through the main frame, the service graph-XML interpreter goes through the XML DTD verification and XML conversion process. Complex data verification is done on the SMS side using the database's stored procedure (SP). Simple checking rules such as data type and length checking are converted to JavaScript and inserted into HTML.

When the converted HTML is delivered to a web browser, a service menu frame 301 representing a service order menu, a main frame 303 for editing a service, a control frame 305 for communicating with an SMS and XML conversion are activated.

7 is a flowchart illustrating an intelligent network service order according to an embodiment of the present invention.

When the customer who subscribes to the UPT service enters the SMS address 401 in order to access the SMS 51, which is the intelligent network service management device, in the web browser 49, the client accesses the service order manager 48 of the SMS (402). The service order manager 48 of the SMS 51 requests the metadata manager 43 to extract metadata having GUI information for the UPT service order editor and then send the metadata to the calling web browser 49.

The web browser 49 starts the service graph editor 44 by using the GUI information downloaded from the SMS 51 (403). When the customer presses the service edit button in the service menu frame 301 of FIG. 6, the service graph editor 44 converts the received GUI XML data into a graph form 405 and displays it in the main frame of 303 of FIG. 6. When the customer completes editing the order data for the UPT service shown in FIG. 4 (406), XML data (see FIG. 3) representing the service order is generated after verification by the service graph-XML interpreter 47 (407). . The generated XML data is transmitted to the SMS server by the SMS communication manager 45 (408) and then converted into FSL data by the XML-FSL interpreter 41 (409). The converted FSL data is transmitted to the SCP by the SMS FSL converter 46 (410) and the FSL interpreter in the SCP controls the service according to the FSL data ordered by the customer (411).

According to the present invention as described above, in order to express the customer order service using XML in the service data and service control logic representation of the service control of the customer, it is possible to express all the order contents desired by the customer in one document In the web browser (not the SMS server), the rule that the service data should have is specified in the Document Type Declaration (DTD) of the service order document. There is an advantage to this.

On the other hand, the present invention is not limited to the above-described embodiment, but can be modified and modified within the scope not departing from the gist of the present invention, such modifications and changes should be regarded as belonging to the following claims. will be.
