Description

Apparatus for adaption of XML in local area wireless communication data}

The present invention relates to an apparatus for applying XML (eXtensive Markup Language) of short-range wireless communication data. In particular, the XML format of the data used for short-range wireless communication enables data integration in short-range wireless communication and communication between heterogeneous protocols. And an XML application device for short-range wireless communication data suitable for controlling hardware consistently.

In general, short-range wireless communication technology refers to performing signal transmission between two terminals wirelessly in a proximity area.

Hereinafter, the conventional technology will be described in the order of Bluetooth, Home RF, WLAN, WPAN, IrDA.

<Bluetooth>

Bluetooth refers to technologies, standards, and products of short-range wireless communication to implement bidirectional short-range communication between information device devices such as mobile phones, PDAs (Personal Digital Assistants), and notebook computers at low cost without complicated wires. The standards mentioned were actually drafted by the Bluetooth Special Interest Group (SIG), a partnership of leading companies in telecommunications, computers, and networks, which were developed for Bluetooth technology development and market formation.

The SIG was launched by Ericsson, IBM, Intel, Nokia and Toshiba as promoters, with more than 1,800 members from 200 member companies at the end of October, 1998, and it is still on the rise. . In December '99, three companies, Microsoft, Motorola and Lucent, participated as promoters.

The version 1.0 Bluetooth specification was released by the SIG in July '99, up to version 1.0B in December '99, and work is currently underway on version 1.1.

Therefore, the company is planning to release products such as software development kits and other key components.

<Home RF>

At the same time as Bluetooth, Compaq, Ericsson, HP, MS, Motorola, Philips, Proxim and Symbionix formed the HomeRF working group (www.homerf.org), using 2.4GHz band carrier frequency. Data rates of 1 Mbps (actual data is 0.8 or 1.6 Mbps) are driving wireless interconnection of consumer electronics within a radius of up to 50 m.

<Wireless LAN>

The WLAN is based on the standards for the physical layer and the data access layer defined in IEEE802.11. Since the WLAN is an asynchronous packet exchange protocol, it is difficult to support voice communication.

In the method using 2.4 GHz frequency hopping, the number of channels and frequency bands are the same as those of Bluetooth in terms of radio standards, and 4FSK (Frequency Shift Keying) can be used in the modulation method. There are some differences in the multiple access method, including support for Direct Sequence Spread Spectrum (DSSS).

<WPAN (Wireless Personal Area Network)>

With the proliferation of companies that support the Bluetooth standard, compatibility issues with WLANs based on the existing IEEE standards have emerged.

WPAN was officially launched in March '99 to establish a standard for short-range personal wireless communication within the range of 10m and supports at least 16 devices from the IEEE802.15 Commission since 1998. After reviewing various standards such as Bluetooth and HomeRF, Bluetooth is finally being established as the 802.15.1 standard.

<IrDA>

IrDA is a near field communication method using infrared (www.irda.org), and the physical layer is completely different from Bluetooth and WPAN using radio waves.

On the other hand, the conventional Bluetooth short-range wireless communication operation method will be described in detail as follows.

1 is a conceptual diagram illustrating an example of a communication method according to a conventional media type.

Thus, in the conventional case, when performing short-range wireless communication, mobile phones perform wireless communication between mobile phones, and remote controllers perform wireless communication with respective control sets and TVs using an existing access network.

As a result, in the related art, communication methods are implemented and implemented according to the types of media.

So what if you want to communicate between different devices?

2 is a conceptual diagram illustrating a conventional use environment of Bluetooth.

Here, reference numeral 1 denotes a headphone stereo corresponding to the MP3, and may transmit and receive music data conforming to the MP3 in a Bluetooth manner. In addition, reference numeral 2 is a headphone for transmitting and receiving music data conforming to the Bluetooth method, and 3 and 4 are a portable terminal and a portable information terminal for transmitting and receiving information data about a song or artist by the Bluetooth method.

In addition, reference numeral 5 is a mobile phone operator for transmitting and receiving data in the IMT-2000 system, 6 is the Internet, and 7 is a storage medium that stores music content such as MP3.

Thus, the network created by Bluetooth that supports communication between multiple devices is called WPAN. In an environment built by WPAN, an information device that a user carries is wirelessly connected to another nearby information device through Bluetooth.

Then, the mobile terminal 3 can be used as a gateway to transmit and receive information content with an external network.

As a result, the portable information terminal (3) (4), which previously functioned alone, cooperates with a peripheral device or a device connected to an external network to provide a convenient function to the user, and to realize an advanced function that has been difficult to realize until now. It is possible.

However, such a conventional technology has many protocols and provides good query data transmission and safety in its own way, but there has been a problem that standardization and publicization of data transmitted and received for communication using such protocols have not been achieved. In other words, the communication between different protocols does not work, and even if a product is implemented using the same protocol, the communication methods that each product controls each other are different and different from each company, so those protocols implemented by a specific company cannot be used. In the case of the used product, although there may be communication with other products of the company, there are problems in that communication with other company products that implement the same protocol is impossible.

In this regard, the present invention is proposed to solve the above-mentioned conventional problems, and an object of the present invention is to perform data integration in short-range wireless communication by XML documenting the format of data used for short-range wireless communication and between heterogeneous protocols. An object of the present invention is to provide an XML application apparatus for short-range wireless communication data that performs communication and can control hardware consistently.

A short range wireless communication adapter for performing short range wireless communication with a short range wireless communication adapter in another product; The technical configuration is characterized by comprising a data / signal analysis unit for configuring the data transmitted and received between the short-range wireless communication adapter in XML, and processing the received XML data / signal.

Hereinafter, an embodiment according to the technical idea of the present invention configured as described above, the apparatus for applying XML of short-range wireless communication data will be described in detail with reference to the accompanying drawings.

3 is a block diagram of an apparatus for applying XML to short-range wireless communication data according to the present invention.

As shown therein, a short range wireless communication adapter 11 performing short range wireless communication with a short range wireless communication adapter 21 in another product; The data is transmitted and received between the short range wireless communication adapters 11 and 21 in XML and includes a data / signal analyzing unit 12 for processing the received XML data / signal.

In the above, the data / signal analyzer 12 refers to a document type definition (DTD) when performing data transmission in XML format.

In the above, the data / signal analysis unit 12 searches for a behavior that can be performed on a product by referring to a DTD, and then configures a predetermined behavior of the product in a standardized XML document, The short-range wireless communication adapter (11) (21) is transmitted through, and the received XML document is analyzed so that the remote control is performed.

The operation of the apparatus for applying XML of short-range wireless communication data according to the present invention configured as described above will be described in detail with reference to the accompanying drawings.

First, the present invention performs XML documenting of data and control signals for standardized data transmission and consistent control signal transmission and processing in one short range wireless communication scheme. In addition, when different short-range wireless communication methods provide a common interface for receiving data transmission between each other, the method provided by the present invention enables consistent equipment control and data transmission and reception between different products and protocols.

In this design, there is no need to mention the protocol. This is because it includes many existing protocols and provides communication methods therein. Therefore, in terms of structure, there is no big change in the protocol related part.

However, according to the present invention, when the pure data and control data are transmitted and received through the protocol, there is only an XML parser so that the contents of the XML document can be grasped in the part of finally analyzing the data.

Therefore, when making a product capable of short-range wireless communication, the data / signal analysis unit 12, 22 is placed in the product, and data transmitted and received between the two short-range wireless communication adapters 11, 21 is transmitted in an XML form. . On the other side of the wireless connection, you can analyze the XML data or control signal received and process the action or data indicated in the content in a predefined format.

Referring to the operation of the present invention in more detail as follows.

When adopting the XML application apparatus of the short-range wireless communication data proposed in the present invention, the communication between the products 10, 20 equipped with two short-range wireless communication adapters 11, 21 is performed as follows. An example of such a method will be described by using a mobile phone equipped with Bluetooth (hereinafter referred to as reference numeral 10) for controlling a refrigerator equipped with Bluetooth (hereinafter referred to as reference numeral 20) as an example.

First, the user wants to control a specific home appliance through Bluetooth mounted on his mobile phone 10. Suppose that the user knows that he wants to control the refrigerator 20, which is a specific household appliance, and tries to turn on the power of the refrigerator 20.

1) Step 1: Search for actions that can be performed on the home appliance.

When transferring data in XML format, DTD (Document Type Definition) is referred to. The DTD is another document that represents the grammar of the XML document you want to send. It can be assumed that the contents are as follows.

<DTD for Consumer Electronics :: Designated by Korea Electronics and Communication Council since 2002.9.10>

[POWER] = 0 (on) 1 (off)

[TIME] = YYYYMMDD HH: mm: SS

[REQUEST] = 100 (system information) 200 (time information) 300 (current status) ......

......

When the user wants to turn on the power for one household appliance, for example, press 3 to select the household appliance, and press 9 to select 0 of the power state. At this time, the intention of the user is made into an XML document.

2) The second step: The confirmed behavior for the home appliance is made in the form of a standardized XML document.

An XML document containing all of the actions specified in the first step is created in the form of a control signal.

<? xml version = "1.0">

<control>

<POWER> 0 </ POWER>

</ control>

These tags are the tags that make up an XML document. This example makes up an XML document. The meaning of this document is that the document was written based on XML version 1.0, has data for control, and instructs POWER to take an action of "0".

In the meaning that POWER defined in the first step can have, it can be seen that if 0, it plays a role of turning on the system, and if 1, a command of turning off the system is shown.

3) Third step: sending and receiving XML documents

Through the second step, an XML document of the desired behavior is created, and this document, that is, data for short-range wireless communication, is transmitted to the target product (system) through protocols provided by each company and standard. Of course, the transmitted data is also received by the short range wireless communication adapter 11 that implements the same (to date) protocol and is transmitted to the data / signal analysis unit 12 that analyzes the data.

4) Step 4: Analysis of XML Document

The data / signal analyzer 12 on the receiving side starts analyzing the received XML document.

Of course, the standard for analysis is based on the DTD mentioned in the first step.

The data / signal analyzer 12 on the receiving side first recognizes that the data received through the tag <control> is externally received to control the system, not merely image or video data for display.

Also, by setting "0" in the <POWER> tag therein, it can be recognized that it is a control signal for turning on the system.

5) 5th step: remote control

Through this series of routines, the user can turn on or off the refrigerator 20 through the mobile phone 10 and control the temperature of the refrigerator 20 or turn on or off the TV.

In addition, through the XML data defined in this way, the user can receive all the information of the home appliances in advance to his mobile phone (10).

<? xml version = "1.0">

<control>

<REQUEST> 100 </ REQUEST>

<RECEIVER> 3Y342DFY25D </ RECEIVER>

</ control>

The document is an XML document requesting the system information for all appliances within a radius of 15M in the mobile phone (10).

<control> transmits 100, which is a control signal and a setting value of <REQUEST>, and requests system information when referring to the DTD of the first step. At this time, the requester's ID is transmitted together. Currently, the unique ID of this mobile phone is designated as 3Y342DFY25D.

All household appliances that have received this (broadcasted) control signal can send their information to <RECEIVER> as follows:

<? xml version = "1.0">

<control> <INFO>

<VENDOR> LGe </ VENDOR>

<PDATE> 2002.09.03 </ PDATA>

<ID> 311949KJD34523 </ ID>

</ INFO> </ control>

Through the data collected by the mobile phone 10, the user can alternatively transmit the desired command and data among the currently searched home appliances.

As such, the present invention is to perform data integration in short-range wireless communication, perform communication between heterogeneous protocols, and control hardware consistently by documenting the format of data used for short-range wireless communication.

While the preferred embodiment of the present invention has been described above, the present invention may use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Therefore, the above description does not limit the scope of the present invention as defined by the limitations of the following claims.

As described above, the apparatus for applying XML of short-range wireless communication data according to the present invention performs data integration in short-range wireless communication by performing XML document format of data used for short-range wireless communication, and performs communication between heterogeneous protocols, and provides hardware. The effect is to have a consistent control.

In addition, the present invention has the effect of controlling several different products (manufacturers of different manufacturers or different manufacturing times) from one controller.

In addition, if the present invention is able to control all home appliances in the network through IP6, and can control it, it is possible to control general electric TV products of General Electric Co., Ltd. in Washington, USA in Seoul, USA through the Internet as well as control through short-range communication. .
