[Wireless] mobile communication terminals currently in use are designed to support one or a number of predefined communication systems so that various modes can be used by the user.

However, since the modes and functions supported by the [wireless] mobile communication terminal are predefined, it is possible to replace the terminal hardware itself in order to access a newly implemented communication system or a new communication system in another region.

Due to the inflexibility of such mobile terminals, SDR (Software Defined Radio) technology has been studied.

This SDR technology is a concept to implement a communication system by processing all parts other than antennas in principle, and changes operating characteristics such as operating frequency, modulation type, bandwidth, network protocols, etc. without changing or adding new hardware. It is a technology that can only be changed.

In terms of the current technology level of hardware, processing up to RF stages in software is not practical, and most of them implement communication systems by processing them in software after the IF stage.                         

If a mobile communication terminal (hereinafter, abbreviated as SDR terminal) that supports at least one mobile communication system is manufactured by using the SDR technology, the function and mode of the terminal can be reconfigured in software unlike a hardware-oriented terminal. have.

The SDR terminal reconfigures the operation mode through program download. For example, to change the terminal currently configured in the CDMA mode to the GSM mode, the GSM Waveform Application is downloaded to reconfigure the terminal.

However, in the related art, if the user's location is not supported by CDMA, the GSM Waveform Application cannot be downloaded through the CDMA wireless link currently supported by the terminal.

Of course, before going to the GSM region, the GSM program must be downloaded in advance using the CDMA radio link. In this case, two problems occur as follows.

First, since the user must know in advance which communication system is used in the place where he wants to move, and the program must be downloaded before the move, the user has a significant inconvenience due to this limitation.

Second, there is no way to verify the downloaded program. In other words, the downloaded program is not supported in the region and cannot be verified at the time of receiving it. Therefore, the downloaded program must be verified after moving to the region. If the verification program does not work, there is a problem that the program cannot be downloaded again.

delete

Therefore, a method for freely downloading a program in any region should be provided through a wireless channel irrespective of a communication mode supported by a terminal. Software download techniques applicable to such SDR terminals can be classified into three categories.

delete

First, there is a method using a subscriber identity module (SIM) or a universal identity module (UIM).

Second, there is a download method through connection with an existing network such as PSTN.

Third, there is a download method using wireless communication.

The operation of each download method is as follows.

1. A method of using a SIM or a UIM, which is a method of reconfiguring a system by transferring a software and control information regarding a part depending on a support mode by attaching and detaching a smart card having a large memory and a microcomputer.

In order to apply this method, among the specifications of the standards to be supported, a module that is implemented in advance in a system that is independent of a radio interface and changes according to a radio interface and parameter information for controlling the same Should be separated, modularized, or libraryized into a smart card.

2. A download method using an existing wired network such as a PSTN, and a method of downloading a system program using a software download service through a wired network.

This method may be the most common solution due to the fact that the wired network is installed in most areas, and that the existing infrastructure can be reused and the high speed data service can be reliably reduced to reduce errors in software download. In terms of convenience, there is a disadvantage in that it is inconvenient in connection with the terminal and the wired network.

3. This is a download method using a wireless method, which is similar in concept to a wired network, except that data and programs for system configuration are downloaded wirelessly.

This method requires a separate channel for program download and increases the download time when the software is large. However, this method is effective in terms of convenience and efficiency.

In particular, recently, due to the implementation of a Bluetooth communication system and the miniaturization and low cost of a wireless LAN, it is considered as a method that can be most efficiently implemented.

Therefore, in order to improve the conventional problem, the present invention searches for a terminal of another person using short-range wireless communication when the SDR terminal is not communicating in the current region, and selects an arbitrary terminal from any SDR server using the discovered terminal as a gateway. It is an object of the present invention to provide a software download system invented for downloading radio waveform applications.

That is, according to the present invention, the SDR terminal can be reconfigured to suit the new network by downloading the software from the server to the SDR terminal using a terminal of another person located around the radio waveform application that supports an arbitrary wireless communication system as a gateway. For the purpose of

And a gateway terminal for accessing and downloading software to the SDR terminal.

The SDR terminal and the gateway terminal are equipped with a Bluetooth module or a wireless LAN module, characterized in that configured to perform short-range wireless communication.

The SDR terminal is configured to search for a gateway terminal using short-range wireless communication and access the SDR server through the found gateway terminal when the call is not possible due to a communication mode that is different from the current region.

The gateway terminal is configured to perform a gateway function when a call is available in the current region and short-range wireless communication is possible.

The gateway terminal notifies the user when a gateway operation is requested from the SDR terminal, and attempts to connect to the SDR server when the user allows the gateway operation. When the gateway terminal is connected to the SDR server, the gateway terminal transmits a gateway operation permission message to the SDR terminal. Characterized in that configured to run.

The gateway terminal is configured to relay a message between the SDR terminal and the SDR server when operating as a gateway.

Terminal 110 downloads new software In this case, when the SDR terminal 110 is connected through the system base station 170, a test terminal 171 for verifying a new software operation state, and informs the user when a gateway operation is requested from the SDR terminal 110, When the user allows the gateway operation, the user accesses the SMS server 180 to receive the access IP of the SDR server 131 and 132 and attempts to connect to the SDR server 131 or 132 using the provided access IP. When connected to the SDR server 131 or 132, the gateway operation permission message is transmitted to the SDR terminal 110 and configured as a gateway terminal 120 executing the gateway operation.

The gateway terminal 120 is configured as an SDR terminal having a gateway function.

The SDR terminal 110 and the gateway terminal 120 is configured to enable short-range wireless communication by mounting the same type of Bluetooth or Wireless LAN.

The SDR terminal 110 checks whether communication is possible in the current region when the power is turned on, and displays if communication is impossible. If the user selects communication software download, the SDR terminal 110 searches for the gateway terminal 120 through short-range wireless communication to access the address and phone. Collects the number and transmits the user's gateway request to the gateway terminal 120, and if the gateway operation is allowed in the gateway terminal 120, the gateway terminal 120 accesses the SDR server 131 or 132 to communicate with the software. It is configured to check the operation of the downloaded communication software to download and access the test terminal 171.
The SDR terminal 110 includes a control unit for searching for at least one or more gateway terminals 120 when there is no software for a mobile communication system serving a current location; It may basically include hardware such as a display unit for displaying the list of the at least one searched gateway terminal 120. In addition, the controller connects to the SDR server 131 or 132 via any one of the gateway terminals 120 selected from the displayed list of the gateway terminal 120 and the software from the connected SDR server 131 or 132. It is possible to download the configuration of such hardware, so the detailed description is omitted.

The gateway terminal 120 checks whether a gateway operation request is made when a call is available in the current region and enables short-range wireless communication when the power is turned on, and notifies the user when a gateway operation is requested from the SDR terminal 110, and the user allows the gateway operation. When connected to the SMS server 180 receives the connection IP of the SDR server 131, 132 attempts to access the SDR server (131 or 132), and when connected to the SDR server (131 or 132) allows gateway operation After the message is transmitted to the SDR terminal 110, a gateway operation is performed to relay a message between the SDR terminal 110 and the SDR server 131 or 132.

The SDR servers 131 and 132 transmit their location information and access IP to the SMS server 180 when the system is booted, and when the gateway terminal 120 is connected, the SDR terminal 110 through the gateway terminal 120. To download the software.

The SMS server 180 searches for the SDR server 131 or 132 closest to the location of the gateway terminal 120 when the SDR server requests an access IP of the SDR server from the gateway terminal 120 and sends a message including the access IP to the gateway. It is configured to provide to the terminal 120.

Referring to the operation and effect of the embodiment of the present invention configured as described above are as follows.

First, the SDR terminal 110 does not have software for enabling wireless communication in the current region, and the gateway terminal 120 is equipped with the same short-range communication system as Bluetooth or WLAN provided in the SDR terminal 110. It is assumed that the SDR terminal is provided with software for enabling wireless communication in the current region.

In addition, the SDR server (131, 132) can be operated by each wireless communication service provider, as well as operating a number of regions by one company, and the software service content of all the servers operated by one communication service provider is the same Assume

When the SDR server 131 and 132 starts to boot the system, the SDR server 131 and 132 access the manganese access device 150 through the Internet 140 to the SMS server 180 through the mobile communication switching station 160 and the current IP address. Send location information (region, etc.)

The SMS server 180 stores the current region and the IP address list of the SDR servers 131 and 132 in the home registry 181, and when the gateway terminal 120 sends a short message to find the SDR server, the gateway terminal 120 After the current location of the gateway terminal 181 is searched for local information stored in the gateway terminal 120, the gateway IP of the closest SDR server 131 or 132 is connected to the gateway terminal in a short message format. Send to 120.

The SDR terminal 110 accesses the gateway terminal 120 to download the wireless communication system software in the current region and then accesses the SDR server 131 or 132 through the gateway terminal 120.

Here, the communication between the SDR terminal 110 and the gateway terminal 120 uses a short-range wireless communication method using Bluetooth or WLAN, and the communication between the gateway terminal 120 and the download server 131 or 132 is CDMA or GSM. Cellular wireless communication scheme, and the like.

The SDR server 131 or 132 selects a wireless communication system software suitable for the specification of the SDR terminal 110 and downloads it to the SDR terminal 110 through the gateway terminal 120.

The above process will be described with reference to the operations of the SDR terminal 110 and the gateway terminal 120 as follows.                     

First, the operation of the SDR terminal 110 will be described with reference to the flowchart of FIG. 2.

The SDR terminal 110 checks whether there is software for performing wireless communication in the current region while the power is turned on to start the system operation or periodically during the operation.

If there is no previously downloaded software or there is software, the SDR terminal 110 notifies the user by displaying it on the LCD panel when the communication method is not available in the current region.

Thereafter, when the user sets the software download, the SDR terminal 110 searches for a gateway terminal providing a gateway function to the SDR server 131 or 132 by performing short-range wireless communication, and then access addresses and telephones of the found gateway terminals. Collect the numbers.

Thereafter, the SDR terminal 110 displays the telephone number list of the collected gateway terminal on the LCD panel.

Thereafter, when the user selects one of the access address and the telephone number displayed on the LCD panel, the SDR terminal 110 accesses the selected gateway terminal ('120' in FIG. 2) and requests a gateway operation.

Accordingly, when the user having the gateway terminal 120 allows the gateway operation, the SDR terminal 110 requests the download of the software to the SDR server 131 or 132 through the gateway terminal 120.

If the user having the gateway terminal 120 does not allow the gateway operation or the connection with the SDR server 131 or 132 fails, the user has another gateway terminal in the list displayed on the LCD panel of the SDR terminal 110. Select to attempt a gateway operation request.

Thereafter, if the gateway operation is not allowed continuously and no further gateway terminal exists, the SDR terminal 110 notifies the user that the gateway terminal cannot be found and terminates the gateway operation request for connection.

Meanwhile, the operation of the gateway terminal 120 will be described with reference to the flowchart of FIG. 3.

The gateway terminal 120 checks whether there is software for performing wireless communication in the current region while the power is turned on to start the system operation or periodically during the operation.

Thereafter, when wireless communication is possible in the current region, the gateway terminal 120 performs short-range wireless communication to check whether there is a gateway operation request from another terminal.

At this time, if there is a request for access information for the gateway operation request from the SDR terminal 110, the gateway terminal 120 asks the user whether to allow the gateway operation.

Thereafter, when the user allows the gateway operation, the gateway terminal 120 transmits a short message to the SMS server 180 requesting an access IP of the SDR server through the system base station 170 and the mobile communication switching center 160.

At this time, the SMS server 180 transmits the IP address and the access port number of the SDR server 131 132 located closest to the gateway terminal 120 to the gateway terminal 120.

The gateway terminal 120 accesses an SDR server (assuming '131' in FIG. 1) using a cellular wireless communication scheme such as CDMA or GSM.

Subsequently, when the connection with the SDR server 131 is successful, the gateway terminal 120 notifies the SDR terminal 110 of the gateway operation using the short range wireless communication method.

Thereafter, when the gateway operation is started, the gateway terminal 120 transmits all messages of the SDR terminal 110 coming from the short range wireless communication link to the SDR server 131 via the cellular wireless communication link and vice versa, the SDR server 131. The message transmitted from the SDR terminal 110 is transmitted.

Thereafter, the SDR terminal 110 downloaded the software from the SDR server 131 is connected to the test terminal 171 through the system base station 170 to check whether the downloaded software is normally operated.

If the user of the gateway terminal 120 does not allow the gateway operation or the connection with the SDR server 131 continues to fail, a message indicating that the gateway operation is not allowed is transmitted to the SDR terminal 110.

That is, the present invention is to allow the SDR terminal that is not currently communicating in the local area to connect to the terminal of the other person using short-range wireless communication, and access the SDR server on the Internet through the terminal of the other person to download the necessary software for communication. .

Meanwhile, the above-described operation of downloading the wireless communication system software from the SDR server 131 or 132 to the SDR terminal 110 through the gateway terminal 120 has been described, but the SDR terminal 110 and the gateway terminal 120 are the same. In the case of a terminal of the type, the gateway terminal 120 may be configured to directly download the software stored in the SDR terminal 110.

In this case, the SDR terminal 110 stores a specific code indicating an operation characteristic, a communication mode, and the like, and transmits the specific code to the gateway terminal 120 when the software is downloaded, and the gateway terminal 120 transmits the specific code transmitted from the SDR terminal 110. You can configure your code to download your own software if it matches your specific code.

As described in detail above, the present invention enables downloading of any cellular wireless communication system software through an access point supporting public wireless communication in an SDR terminal equipped with a public wireless communication system such as a Bluetooth module or a wireless LAN. As a result, various problems of downloading from an existing cellular radio link such as CDMA or GSM can be improved.

In other words, the present invention is to download a program when reconfiguring the terminal when entering a cellular network area that is not supported by the current terminal in order to realize global roaming when there is a different type of cellular network in each region, even in a new cellular network It is effective to enable communication without changing hardware.
