Definitions

• the present invention relates to a data transmission system using radio transceivers and, more particularly, to a innovative data transmission system without dedicated communication lines using radio transceivers so that the cost of operation and maintenance of the system can be reduced and the security of transmitted informations can be guaranteed.
• character transmission services that enable character data to be transmitted between cellular phones have been available.
• characters input to a cellular phone by a user are encoded into character data in the processor of the cellular phone and then transmitted to another user's cellular phone through a relay center of a cellular phone company.
• the received character data are decoded into characters in the processor of another user's cellular phone and the characters are displayed on a display portion of the cellular phone.
• Fig. 1. represents a block diagram of a conventional data transmission system for the character services, and is illustrative of an example of a data transmission system transmitting internet e-mail to a user' s cellular phone.
• the data transmission system consists of carrier 2 such as cellular phone company, relay company 4 connected to carrier 2, and server 6 operated by information provider (IP) 8.
• IP information provider
• the server 6 serves as a E-mail server when users or client transmit e-mail through internet.
• the relay company 4 is connected to respective carrier 2 through dedicated communication line in order to connect each other at any time, and the IP 8 is connected to the relay company 4 through internet.
• the server 6 transmits the e-mail to relay company 4. And then the relay company classifies the received e-mail transmitted by the server 6 and transmits the e-mail in the form of character data to the corresponding carrier 2.
• each carrier 2 encodes the received character data and transmits the data to each user's cellular phone 10 through his owned relay center. Finally, the data which are transmitted to user's cellular phone 10 are decoded and displayed in the form of characters.
• the above mentioned data transmission system can be broadly used to applications such as transmissions of bank account details, stock information service of security company, credit transaction details of credit card company, work orders of transportation company as well as e-mail transmission.
• the above mentioned data transmission system has problems.
• One of the problems is that the construction of the above mentioned data transmission system is not only complicated and also increases cost for dedicated communication line 11 because the relay company 4 and the carrier 2 are always connected with the dedicated communication line 11.
• Another problem is security problem, that is, the content of e-mail is exposed to the relay company 4 and the carrier 2 because the e-mail are supplied in the form of characters.
• an object of the present invention is to provide a innovative data transmission system using radio transceivers with which cost can be reduced without any dedicated communication lines and which can maintain secrete for transmitted information.
• a data transmission system for transmitting a predetermined data being provided by IP 8 to a first radio transceiver 10 of a receiving user side
• the data transmission system comprising: a server 6 operated by the IP 8; and a second radio transceiver 16 of a sending user side connected to the server 6 , wherein the server 6 being provided with a control program to control the second radio transceiver 16, and data of the server 6 input to the radio transceiver 10 being transmitted to the radio transceiver 16 through a relay center 9 of a carrier.
• FIG. 1 is a view illustrating the conventional data transmission system
• FIG. 2 is a view illustrating the conventional data transmission system using a radio transceiver according to the embodiment of the present invention.
• radio transceiver in the specification refers to a wireless or radio telecommunication terminal such as cellular phone, CDMA and TDMA handsets, Iridium handset, pager, international mobile telecommunication 2000(IMT-2000) handset so on.
• Fig. 2 is a view illustrating the conventional data transmission system using a radio transceiver such as cellular phone according to the embodiment of the present invention.
• the e-mail data transmission system using a radio transceiver 16 for transmitting character data to the receiver through the relay center of carrier includes server 6 operated by IP 8 and a plurality of radio transceivers 16 parallel -connected to serial ports of the server 6.
• the server 6 which functions as a server of receiving e-mail and then classifying and identifying it, and it is provided with a control software for controlling the radio transceiver 16.
• the control software functions as inputting whether a e-mail is received, the information of e-mail, for example, the content of e-mail and the number of e-mail or likes, and the receiver's phone number to the radio transceiver 16.
• user transmits the e-mail including the receiver's phone number to the server 6 using his own internet terminal through internet, and then the server 6 receives the e-mail and classifies and identifies it to construct database. And then the server 6 transmits the e-mail information and the phone number written in the database by inputting them to the radio transceiver 16.
• the e-mail information input to the radio transceiver 16 is encoded and transmitted to the receiver's radio transceiver 10 through the relay center of carrier 2.
• the e-mail information is received and decoded at the receiver's radio transceiver 10 and then displayed in the form of characters.
• the radio transceivers 16 may be connected to other ports of the server 6, or only- one radio transceiver 16 may be connected.
• the data transmission system of the present invention since the data transmission system can transmit the predetermined information to the receiver with the radio transceivers 16 and 10, any additional dedicated transmission line is not required and so the cost of maintaining the system is reduced. And Also, since the information supplied to the receiver is transmitted after being encoded, apart from the conventional data transmission system in which the data in the form of characters may be revealed by the relay company 4 and/or carrier 2, the data transmission system according to the present invention makes sure of security of the information.
