Apparatus and method for converting telegram in data communication}

The present invention relates to an apparatus and method for converting a communication message in a data communication process, and more particularly, data that can be converted into an XML form and can be suitably provided in a specialized format of a specific business service. An apparatus and method for converting a telegraph in a communication process.

In general, data communication refers to the exchange of data information through a communication network using an information processing device such as a computer or a terminal. In other words, the devices that perform the functions of collecting, processing, processing, storing, and distributing digital information displayed in binary numbers are connected to the telecommunication lines to communicate with each other. Since the device is mainly a computer, data communication is also referred to as computer communication, and in some cases, the data communication is defined by including not only data communication but also data processing by a computer.

In addition, the communication can be largely divided into voice communication and non-voice communication, there are cases where both non-voice communication is regarded as data communication. Data communication is a more advanced communication than the conventional communication that attempts to deliver an object to be transmitted, such as a telegram or a telephone, to a receiver without error, and may be referred to as a flexible communication including processing and deformation of an object. Basically, it consists of a data terminal device and a data line termination device.

In the case of such data communication, web service support, telephone (phone: wireless telephone including wired or various mobile phones), personal information terminal, and other mobile devices are generally supported according to specific business services. It is a reality that a separate system is built for each channel to support the script method of and support various channels such as VM, Brew, PDA application.

In the case of such a specific business service using the Internet, there is a problem in that it is not possible to provide differentiated services for each user because the integration of information scattered by each operating system is not made.

In addition, the existing data communication process requires the user to know the names, types, lengths, positions, etc. of all fields when analyzing and assembling the communication text regardless of the language used in the development. There is a problem that must be implemented through a specific development language (code).

The present invention is to solve the above problems of the prior art. That is, an object of the present invention is to provide an apparatus and method for converting a communication message in a data communication process that can provide an input communication message in accordance with a special format of a specific business service.

The present invention as a technical concept for achieving the above object, the input unit receives a telegram received from a remote (telegram) to extract information about the field from the communication message, and to analyze the information about the extracted field An analysis unit for separating fields according to the types of fields and creating a field list, an XML conversion unit for converting the field list into an XML (eXtensible Markup Language) format and creating the XML file, and a telegram format in any host ( If a format is provided, the data written in the XML file is loaded into a memory space through an XML parser, and the data of the loaded XML file is loaded in a designated location in accordance with a telegram format provided by the host. And a response object creation unit for creating a response object and providing the response object to the host. Professional communication emitter in communication process (telegram) provides a conversion apparatus.

According to the present invention, by converting the inputted communication text into XML format and providing it according to the specialized format of a specific business service, the cost reduction and program change task minimization, SW upgrade and The distribution risk due to the upgrade is reduced.

It also has the effect of reducing software bugs by separating data and code.

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

As shown, converting a telegram in a data communication process according to an embodiment of the present invention first receives the received telegram 10 from a remote location and separates it for each field.

The separated fields are analyzed by the analyzer 20, classified according to the type, and a field list is prepared.

The created field list is converted into an XML (eXtensible Markup Language) format to create an XML schema file 30.

If a telegram format is provided from any host, the XML schema file 30 is analyzed according to XML syntax order through the assembler 40 to obtain corresponding field values, and the obtained field values are host. Load and assemble in the designated location according to the professional format provided by.

Finally, the response message 50 assembled in the assembly machine 40 is provided to the host.

2 is a block diagram showing a communication specialized converter 100 in a data communication process according to an embodiment of the present invention.

As shown, in the data communication process according to an embodiment of the present invention, the communication conversion apparatus 100 receives an input of a telegram received from a remote place and extracts information about a field from a communication message ( 110), the analysis unit 120 for analyzing the information about the extracted field to separate according to the type of the field and to create a field list, converting the field list in the form of XML (eXtensible Markup Language) to create an XML file When the XML conversion unit 130 and a telegram format are provided from an arbitrary host, the XML file is loaded into a memory space through an XML parser, and the data of the loaded XML file is loaded. Creates a response object by loading it in a designated location in accordance with a telegram format provided by the host, and sends the response object to the response object creating unit 140 that provides the host. It is composed.

The extraction unit 110 first receives a telegram received from a remote site, and extracts information about a field from a communication message including the field, the field value, and the like.

The analysis unit 120 analyzes the information about the extracted fields, separates them according to the types of fields, and creates a field list.

The XML conversion unit 130 converts the field list into an XML form, and then validates it with an XML schema that is defined separately (where field attributes such as name, length, type, location, etc. are defined) and create the XML file. do. The XML schema will be described later in detail.

In addition, when the requirements necessary for customer business services are added or the technical specification is changed, the XML schema is re-defined to convert the field list into the XML format, and then verified by the redefined XML schema to be written as an XML file.

When the response object creation unit 140 requests data conforming to a professional format from any host 200 for use in a specific business service, an XML file is loaded into a memory space using an XML parser, The data of the loaded XML file is loaded at a designated position in accordance with a telegram format provided by the host 200 to create a response object and provide the response object to the host 200.

That is, the XML file is analyzed according to the XML syntax order to obtain the corresponding field values, and the response object is created by loading the obtained field values in a designated position in accordance with the specialized format provided by the host 200 and creating the response object. It provides to the host 200. The XML parser will be described in detail later.

3 is a flowchart illustrating a communication telegram conversion method in a data communication process according to an embodiment of the present invention.

As shown, in the data communication process according to an embodiment of the present invention, the communication message conversion method first receives a telegram received from a remote place (S100).

Thereafter, information about a field is extracted from the input communication message (S110). The communication message includes a field, a field value, and the like.

The information about the extracted field is analyzed, separated according to the types of fields, and a field list is created (S120).

In addition, the field list is converted into an XML (eXtensible Markup Language) format and created as an XML file (S130). That is, the field list is converted into an XML form, and then verified with a separately defined XML schema and stored as an XML file in a web server. In the XML schema, name, length, type, position, and the like which are attributes of a field are defined.

Schema defines the properties of the class of an object. In the case of XML, a schema is a definition of how a document is marked up.

From the application developer's point of view, a schema is a set of rules about what can be contained in an XML document. Because of the schema, programmers can create software that extracts and processes specific information placed in a specific way within a document without any ambiguity or confusion. The validity of the document is also determined based on the schema. If a document is valid based on a schema, validating the document based on that schema will increase the confidence that the information you want to communicate with will be properly understood and used by the other party.

Therefore, when using XML schema, all expressions such as inclusion relations between elements, order using connector, and occurrence indicator are expressed as XML schema, along with definition of element, attribute, etc. that is basically performed when modeling certain information into XML. It is possible to use data types defined in XML schema and user-defined data types defined by each element and attribute.

These XML schemas can be used for various purposes such as converting the contents of a database into XML or storing XML in a database, type-based validation, schema-based document editing, and reuse of XML schemas in a text editor.

On the other hand, when the requirements necessary for customer service services are added or the technical specification is changed, the XML schema is redefined, the field list is converted into an XML format, and then verified with the redefined XML schema and stored in the web server as an XML file.

In other words, by adding, modifying, and removing the requirements of the developed process through the XML file, only the modified XML file is distributed, thereby minimizing program change work and reducing the distribution risk due to SW upgrade and version upgrade.

It is determined whether a telegram format is provided from an arbitrary host (S140). When the telegram format is provided, data written in the XML file is loaded into a memory space through an XML parser (S150). That is, when a certain host requires data in a certain format for use in a specific business service, an XML file is loaded into a memory space using an XML parser.

 Reading an XML document and converting it into an internal representation that other programs or subroutines can use is called parsing. A parser is called a parser. Therefore, an XML parser is a module that interprets XML documents. Since an XML document is composed of tags that are arbitrarily defined, an XML parser, which is a module that wants to correctly read and extract the data, is required.

After the XML parser reads the XML document, it creates an XML parser tree structure, extracts the elements and attributes of the read XML document using the DOM API, SAX API, etc., and then manipulates the XML document. (Add, delete, update).

A response object is created by loading the data of the loaded XML file in a designated position according to a telegram format provided by the host (S160). In other words, the XML file is analyzed according to the XML syntax order to obtain the corresponding field values, and the response object is created by loading the acquired field values in the designated position according to the professional format provided by the host.

Thereafter, the response object is provided to the host (S170). That is, the response object is provided to the host so that the response object can be used for a specific business service.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and it is common in the art that various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be clear to those who have knowledge of God.
