The present invention distributes and distributes the information concentrated in the relay server of the wired Internet to the wireless communication device, and enables direct data transmission and reception between the wireless communication devices without the support of the relay management server on the Internet. It is to provide a wireless communication device that overcomes the limitations and limitations of server-based wired Internet and enables more active and smooth multilateral information provision and sharing.

The wireless Internet was developed to use the wired Internet in a wireless environment, and includes the advantages and disadvantages of the wired internet with the limitations of the wireless environment. Existing wired Internet is offline in terms of increased interaction between company and customer (B2C), active access of time-independent information, and multi-party information provision and sharing based on client / server technology. It has advantages that it did not have. However, because all the information is concentrated on the server, if the number of concurrent users increases, the performance of the server is drastically deteriorated, and the confidentiality, integrity, user authentication, and non-repudiation for security or protection of the concentrated information are incomplete. The serious problem that arises is that it is one of the major drawbacks of the existing wired Internet. Mobility and portability that the wireless Internet can include the advantages and disadvantages of the wired Internet as it is, and can be used more freely in the constraints of time and space than the wired Internet due to the light weight of the wireless Internet terminal device. ), And on the contrary, system performance is lower than that of a desktop computer.

Wireless Internet has not yet been stabilized due to the advantages and disadvantages of the existing wired Internet and compatibility problems of wired and wireless environments. At present, various organizations including domestic and overseas are presenting technologies for each system. Prior to the detailed description of the present invention to discuss the wireless Internet technology that is being carried out to date, so far, the applicable technology in the country so far, WAP (Wireless Application Protocol) Forum WAP, Microsoft's MME (Microsoft Mobile Explorer), Japan NTT DoCoMo i-mode, and Samsung's AnyWeb, are compressed into four types.

The wireless Internet technology basically has a structure as shown in FIG. WAP is an application protocol defined for efficiently providing Internet services in wireless networks. It is a standard guideline for providing information suitable for wireless networks and controlling wireless network services. It has started to be designed as a global open standard for wireless network applications. . WAP plays a wired / wireless buffer role by using a gateway assigned a fixed IP address at the point where wired and wireless meet to use a server of a wireless communication device and a wired Internet. By this gateway, the wireless Internet communicates between the user's terminal and the gateway using the protocol defined in the WAP, and the Internet server is connected to the existing wired Internet network. Therefore, in the WAP-based wireless Internet, the gateway automatically converts WML (Wireless Markup Language) and HDML (Handheld Device Markup Language) from the WAP-based wireless Internet to HTML of the HyperText Transfer Protocol (HTTP) -based wired Internet.

WAP basically provides functionality similar to the OSI 7 layer of wired Internet, so it has an architecture that can be easily applied from the wireless environment to the wired environment. The WAP structure is shown in Figure 2, and the WSP (Wireless Session Protocol), which performs the same function as HTTP of the wired Internet, overcomes the limitation of low bandwidth, and the WTP (Wireless Transaction Protocol) ensures stable data transmission. Wireless Transport Layer Security (WTLS) acts like Secure Socket Layer (SSL), responsible for the security of the wireless Internet. Currently, SK Telecom plans to implement or employ WAP services based on WML, while Shinseon Telecom and LG Telecom will implement or implement WAP services based on HDML.

MME of the wireless Internet is a wireless Internet technology that allows the mobile explorer (ME) of the mobile communication terminal to perform some functions performed by the gateway to compensate for the WAP, which is dependent on the gateway that plays a wired / wireless buffer role. MME uses m-HTML as a base language that reduces the HTML of the wired Internet to a form optimized for a wireless environment, instead of a WAP-specific language such as WML or HDML, so there is no need for wired / wireless protocol conversion at the gateway level. However, the gateway of the MME only needs to play a role of controlling large data transmission and modifying it for a wireless environment for smooth wired and wireless Internet communication. However, some functions of the gateway are embedded in the wireless communication terminal, thereby affecting the terminal system performance more than the WAP. Currently, Korea Telecom M.com provides MME solution among domestic operators.

I-mode of wireless internet is a wireless internet service developed by NTT DoCoMo, a Japanese mobile operator. Currently, Japan has a significant amount of subscribers and is the only successful wireless Internet technology to date. i-mode uses c-HTML (compact-HTML), which is a miniature version of wired Internet HTTP, and i-mode gateway, like MME, controls wired and wireless Internet communications.

AnyWeb of Wireless Internet is a wireless internet solution jointly developed by Samsung Electronics and AI-net. It uses s-HTML (small-HTML), which is a miniature version of wired Internet HTML. AnyWeb also uses a gateway called Mproxy server to act as a wireless and wireless buffer.

The common point of the wireless internet service presented in the above four cases is that the data file transfer is all provided from a relay server on the internet, and thus has limitations and limitations in exchanging various information among a plurality of clients using the wireless internet. Degradation of file transfer rate due to the overload is also a problem.

The present invention for overcoming the above problems, by overcoming the limitations and limitations of the relay server-based wired Internet from the viewpoint of the wireless Internet, by distributing the information concentrated on the server of the wired Internet to the wireless communication device It is an object of the present invention to provide a wireless communication device that can realize more active and smooth multi-party information provision and sharing.

In addition, the present invention is compatible with all the various wireless Internet technologies described above, and can be easily upgraded even after the completion of the wireless Internet standards in the future, as well as for the roaming service between different communication service systems as shown in Figure 1 The purpose is to implement direct data communication between wireless communication devices using only software technology on the wireless Internet system.

It is also an object of the present invention to implement direct data communication between wireless communication devices without the support of a relay management server on the Internet.

The present invention distributes and distributes the information concentrated in the relay server of the wired Internet to the wireless communication device, and wireless communication devices (mobile communication terminals, PDAs with CDMA functions, smart phones, all communication capable of wireless communication such as IMT 2000). By enabling direct data transmission and reception between devices without the support of a relay management server on the Internet, it overcomes the limitations and limitations of the client server-based wired Internet in terms of wireless Internet, and provides more active and smooth multi-party information. It is to provide a wireless communication device capable of providing and sharing.

In addition, the present invention serves as a wireless network connection path between a wireless communication device using a wired and wireless Internet network and the wireless communication device, and includes a gateway for assigning a fixed address or a dynamic address when the wireless communication device accesses the wireless Internet network. A server performing unit configured to extract shared file data information from an internal data base (DB) of the wireless communication device and deliver the shared file data information to a distributed network connection unit; A distributed network connection unit which receives the shared file data information from the server performing unit, stores the shared file data information in a shared file data information DB, and exchanges shared file information between wireless communication devices through a wireless Internet network; And generating a query for the data data to be searched and transmitted to a distributed network connection in another person's wireless communication device through a wireless Internet network, and receiving the shared file data information DB search result connected to the distributed network connection, and receiving the received result. When the file data for communication connection is selected based on the above, the client establishes a network path to the wireless communication device to which the file data is shared through the gateway, and downloads data directly from the wireless communication device to which the file data is shared. Performing unit; characterized in that comprises a.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the following examples are one of several methods for most appropriately explaining the present invention, and the present invention is not limited to the following examples. In addition, for convenience of reference numerals, a wireless communication device is referred to as M2M (Mobile-To-Mobile).

3 is a basic configuration diagram for direct data communication between wireless communication devices, and FIG. 4 is an internal block diagram of a wireless communication device application program for direct data communication between wireless communication devices.

The present invention provides a method of accessing a server of a wired internet by assuming a wireless communication device as a simple client, whereas the existing wireless internet (Fig. 1) has an independent address having a unique address in a wired / wireless integrated internet network. It is assumed that the host, and the internal data communication between the wireless communication device is implemented by installing a wireless communication device application program including a server execution unit and a client execution unit internally.

After booting, the wireless communication device connects to the wireless Internet network and simultaneously allocates a static address set internally or a dynamic address from the gateway 16. The gateway 16 confirming the address of the wireless communication device updates the network information of the device.

Referring to the operation process of the server performing unit 11 of the wireless communication device application program 10, file information, network environment information, user information, etc. for the shared data in the internal data base (DB) 15 of the wireless communication device. It extracts the indirect information of the same shared file data and delivers it to the distributed network connection unit 13 below.

The distributed network connection unit 13 that receives the information on the shared data from the wireless communication device stores the shared file data information in the shared file data information DB 14 and receives a request for information from the client performing unit of the wireless communication device. After searching the shared file data information DB 14, the result is returned to the client execution unit 12.

In the operation process of the client execution unit 12 of the wireless communication device application program 10, the client execution unit 12 generates a query for the data data to be searched to download the desired data, and then the others through the wireless Internet network. It transmits to the distributed network connection unit 13 in the wireless communication device, and retrieves the shared file data information DB 14 connected to the distributed network connection unit 13 as shown in FIG.

 The distributed network connection unit 13 that receives the information retrieval request from the wireless communication device client performing unit 12 searches for the shared file data information DB 14 and includes various contents about the address and the sharing information of the wireless communication device. Return the Embeded Object to the client execution unit 12.

When the wireless communication device client performing unit 12 receives information on data to be downloaded from the distributed network connection unit 13, the wireless communication device client performing unit 12 outputs the result to the screen as shown in FIG. 6. And part or all of the data can be downloaded as shown in FIG.

8 is a diagram illustrating a process of transmitting data from the server performing unit 11 of the wireless communication device to the client performing unit 12 of the other wireless communication device.

The server of the wireless communication device in which shared data is stored by the client performing unit 12 of the wireless communication device application program 10 based on information received from the distributed network connection unit 13 in the third party wireless communication device on the wireless Internet. Referring to the process of visiting the performing unit 11, the wireless communication device application 10 operating in the client mode (20A) is a gateway by referring to the information received from the distributed network connection unit 13 in the third party wireless communication device Request 16 to establish a route to the corresponding wireless communication device application 10 operating in server mode 20B.

The gateway 16 checks whether the wireless communication device is in a communicable state by a request of the wireless communication device application 10 operating in the client mode 20A, and performs a server of the wireless communication device application 10. Set the path to section 11 and return the result.

When the path to the server mode 20B wireless communication device application 10 is established, the client mode 20A wireless communication device application 10 may execute the server execution unit 11 of the corresponding wireless communication device application 10. Ask to send the desired data from the shared data.

The server mode 20B wireless communication device application 10 that has received the data transmission request transmits data along the path to the client mode 20A wireless communication device application 10.

At this time, the gateway 16, like the existing wireless Internet, controls data transmission and checks the communication status to ensure stable communication.

9 is a block diagram of an existing wireless network based on a voice call, and FIG. 10 is a system configuration diagram for direct data communication of a radio communication period with different mobile communication systems, and FIG. A digital data flow chart illustrating the data transfer process.

All mobile communication systems are connected by wire except for the base station and the wireless communication device as shown in FIG. 9, and roaming communication between different operators is also connected by wired network.

The wired network can be connected directly by a strategic alliance between operators, or by using a wired system of a public payphone network.

For the same reason, the gateway 16 of the wireless Internet network for digital data communication also uses a wired network to connect different mobile communication providers.

In addition, as described above with reference to FIG. 1, since all wireless Internet networks use the gateway 16 to perform a wired / wireless buffering role, the gateway 16 of each mobile carrier is directly connected to a wired Internet network or directly. It communicates using a high speed dedicated line.

For this reason, even if a wireless Internet user using different mobile communication networks share the same wireless communication device management server, direct data communication between wireless communication devices is possible as shown in FIG. 11 based on the above description.

A more detailed description of a direct data communication method between wireless communication devices between a single wireless Internet network and different mobile communication systems will be described with reference to a flowchart.

12 is a flowchart illustrating a process of allocating a wireless Internet address and accessing the gateway 16 after the wireless communication device is booted.

After the wireless communication device is booted 1201, when the wireless communication device application 10 is executed, the wireless communication device application 10 checks whether a fixed wireless Internet address exists (1202).

If it is confirmed that a fixed wireless Internet address exists, the wireless communication device application 10 assigns a wireless Internet address of the wireless device to that address (1203).

After checking whether the connection to the gateway 16 is possible (1204), the controller 16 accesses the gateway 16 (1205).

On the contrary, if there is no fixed address currently assigned to the wireless communication device, after confirming that the gateway 16 can be connected (1206), the gateway 16 is connected (1207), and the dynamic address is allocated from the gateway 16. (1208).

When the address of the wireless communication device is assigned and the wireless communication device application 10 accesses the gateway 16, the gateway 16 stores the network settings of the wireless communication device, and then connects the wired / wireless network path to the management server. Set (1209).

When the network setting of the wireless communication device is stored and the path between the wireless communication devices is secured, the gateway 16 checks whether the mobile communication service is roaming support with another mobile communication service (1210). If roaming with another mobile communication service, the gateway 16 shares the network environment of the wireless communication device stored in the mobile communication system (1211), thereby ensuring a direct data communication system between wireless communication devices between different communication systems. .

FIG. 13 is a flowchart illustrating a process of searching for and downloading desired data by using the client execution unit 12 of the wireless communication device application program 10.

The client execution unit 12 of the wireless communication device application 10 generates 1301 a query of the material to be searched and transmits this query to the distributed network connection unit 13 in the third party wireless communication device on the wireless Internet. In operation 1302, the shared file information DB is retrieved (1303).

If the shared file information DB search result exists, the distributed network connection unit 13 generates a search result (1304) and returns it to the client execution unit 12 of the corresponding wireless communication device application program (1305).

On the contrary, if the search result does not exist, the distributed network connection unit 13 transmits an error message to the client execution unit 12 and terminates (1306).

The client execution unit 12 receiving the search result from the distributed network connection unit 13 selects a user's input or data to be automatically downloaded (1307), and wireless communication in which the shared data exists through the gateway 16. The server requests a path setting to the server execution unit 11 of the device (1308).

The gateway 16, which has requested a route setting from the client execution unit 12 of the wireless communication device application program 10 to the server execution unit 11 where the shared data exists, is assigned to a gateway managed by the corresponding wireless communication device. 16) Check whether it exists inside or outside the mobile communication system (1309).

If the server execution unit 11 is present in the gateway 16, it is determined whether the connection with the corresponding wireless communication device is possible (1310) and set to download the shared data (1311). On the contrary, if the server execution unit 11 of the wireless communication device does not secure the connection, the gateway 16 waits for a predetermined time until the connection state is secured (1312).

If the connection is reestablished in the given time (1313), reset to download the shared data, and if the connection is not secured after a certain time, an error message to the client execution unit 12 confirming that the connection is disconnected Transmit (1314).

If the wireless communication device does not exist inside the gateway 16, the gateway 16 may transmit to another gateway 16 managing the wireless communication device or the gateway 16 of another mobile communication system capable of roaming service. A connection is made (1315).

If the other gateway 16 is successfully connected, referring to the corresponding gateway 16, after confirming that the connection with the server performing unit 11 of the wireless communication device is possible, the shared data is set to be downloaded.

If the data download is completed from the wireless communication device server performing unit 11 to the wireless communication device client performing unit 12 of the other wireless communication device through the gateway 16 (1316), the operation ends.

On the contrary, if it is still being downloaded or if the download is not finished, the wireless communication device client execution unit 12 or the gateway 16 checks whether the connection with the corresponding server execution unit 11 is possible (1310). Repeat the information.

By performing the above operations, the wireless communication device server performing unit 11 directly from the wireless communication device server performing unit 11 to the other wireless communication device client performing unit 12 extends the advantages of mobility and portability of the wireless Internet. Data communication is secured.

According to the present invention, by distributing the information concentrated in the server of the wired Internet to the wireless communication device, it overcomes the limitations and limitations of the relay server-based wired Internet from the viewpoint of the wireless Internet, more active and smooth multi-party information It has the advantage of providing and sharing, and by directly implementing data communication between wireless communication devices using only software technology on the basic wireless internet system, it is compatible with all existing wireless internet technologies, Not only can this be easily upgraded after completion, but also has the advantage of enabling roaming services between different communication service systems.

In addition, there is an advantage to implement direct data communication between wireless communication devices without the support of the relay management server on the Internet.
