DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio transmitter / receiver, and more particularly, to a method for reprogramming a radio transmitter / receiver in a radio broadcast.

[0002]

2. Description of the Related Art Wireless transmitters / receivers (transceivers), such as wireless telephones, are designed to operate on a particular type of network, such as GSM900 or DCS1800.

However, the intended use of wireless telephones in a particular network in a restricted geographical area requires that the telephone configuration be capable of properly communicating in that particular network.

[0004] Wireless telephone users typically have telephones that are configured for communication with a so-called "home network." The home network is the local network typically used most by subscribers.

[0005] However, the area available to users, such as GSM radiotelephones, is rather large and is not limited to home networks, but can be used in many other networks worldwide. The use of wireless telephones outside the home network is referred to as "roaming.
ng) ".

When a wireless telephone is used for roaming, it is often necessary to provide the telephone with a configuration different from the configuration used in a home network. Therefore, a general wireless transmitter / receiver can be reconfigured by a signal received from the wireless communication interface. It is also convenient to be able to reconfigure the radio with a wireless communication interface to support various communications and user applications, such as adding an address book manager, whether or not the radio is in the home network.

[0007] Wireless communication reprogramming of wireless receivers is well known and is described, for example, in US Patent No. 5,381,138. The ability to obtain programming data from a network is particularly useful in roaming wireless transmitters / receivers.

[0008] Dual or multimode radio transceivers for multiple networks are known. These dual or multi-mode wireless transceivers may be manufactured to be used as one unit, or may be provided as separate units that are connected to each other or used in conjunction with one another.

[0009]

At present, reprogramming in radio broadcasting is limited to one network. That is, the cellular network reprograms only those portions of the transceiver that operate with the cellular network.

[0010] It is an object of the present invention to provide a method of downloading reprogramming data in wireless broadcasting, which enables reprogramming in wireless broadcasting for a plurality of networks to be used in a dual-mode or multi-mode transceiver. And

[0011]

According to the present invention, there is provided the following:
A method for downloading reprogramming data in a wireless broadcast for installation on a first wireless transceiver configured to operate on a second network, wherein the reprogramming data operates on the second network from a second network. The reprogramming data sent to the second wireless transceiver, which is sent to the second wireless transceiver, is sent to the first wireless transceiver, and then the reprogramming data is installed in the first wireless transceiver. , Thereby enabling the second wireless transceiver to communicate with the first network.
Network .

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram for explaining a method for downloading reprogramming data in wireless broadcasting according to the present invention.

As shown in FIG. 1, the dual mode transceiver 1 is provided with a "stand-alone" unit 2 which is a cellular telephone and a satellite unit 3. The satellite unit 3 operates on a satellite network 4. The cellular unit 2 can be detached from the satellite unit 3 and can operate separately from the cellular unit 2. However, these two units can be connected to take advantage of mutually beneficial functions and additional services available. For example, power supply from one unit may be used to assist or replace power supply from the other unit.

Further, both units can be connected by optical means such as IR. If there is a need or desire for reprogramming, a request to download a programming module is sent from the cellular unit 2 to the cellular network 5 or from the satellite unit 3 to the satellite network 4. It would be possible to request the necessary programming modules to reconfigure the phone for use in the area where the roaming occurred.

[0016] Alternatively, a request can be made to download another user application module, such as an address book manager.

However, the request in this embodiment is that the satellite unit 3 is reprogrammed and the satellite unit 3
And the cellular unit 2 so as to operate the cellular unit 2 in the satellite network 4.

Cellular unit 2 requests download from cellular network 5 and prepares for data reception and transmission. The transmission characteristics when transmitting the required module depend on the amount of data received by the cellular unit 2, the bandwidth of the communication channel and the amount of memory available in the receiving device.

The communication of data modules from the cellular unit 2 to the satellite unit 3 also depends on the link that exists between the two units. For example, when connected to each other via a plug-and-socket connection (wired connection), the transfer of the reprogramming module from one unit to the other unit can be at radio frequency (RF),
No conversion of the reprogramming module to the baseband frequency is required.

If both units are physically separated and an optical link exists between the units, it is necessary to convert the received RF signal from the network to a baseband frequency in order to carry out the reprogramming module transmission. is there.

Each of the cell type unit 2 and the satellite unit 3 has a memory portion such as a flash EPROM which can be written with received data. Received data for reprogramming is received and stored by the cellular unit 2.

Next, the reprogramming data in the memory of the cellular unit 2 is transferred to the memory of the satellite unit 3. Upon completion of receiving the reprogramming data in the memory of the satellite unit 3, the reprogramming data is installed in the satellite unit 3 at all levels. With proper buffering and control, both units 2 and 3 can share memory.

In the above example, the two units are separable, but some dual-mode designs build a single radiotelephone unit mode for use in two different networks.

Therefore, the dual mode telephone can be made as a single unit, and its design can have many functions common to both use modes. That is, many of the components of the telephone, such as the keypad, power supply and some memory, are effectively shared between the two use modes.

In the method for downloading reprogramming data by wireless broadcasting according to the present embodiment, the first wireless transceiver is a part of a wireless telephone operable on the first network, and the second wireless transceiver is the second wireless transceiver. It can also be used for a dual-mode wireless telephone, which is a part of a wireless telephone operable on the same network.

[0026]

As described above, the present invention is configured as described above, so that the reprogramming in the radio broadcasting for a plurality of networks can be used in a dual-mode or multi-mode transceiver.
