Abstract: PURPOSE: A method for reducing delay of a voice transmission in a digital voice communication system is provided to abandon data whose packet data rate in a wireless terminal is less than a predetermined rate, when voice delay occurs, thereby reducing the voice delay. CONSTITUTION: A wireless terminal measures a recovery time whenever a voice block is generated(10). The wireless terminal compares the recovery time with a reference value(12). If the recovery time exceeds the reference value, the wireless terminal stores packet data only whose data rate is more than a predetermined rate among packet data generated from a vocoder, and generates the voice block(16). If the recovery time is less than the reference value, the wireless terminal stores all the packet data, and generates the voice block(14). The wireless terminal transmits the generated voice block to a TCP layer(18).

Abstract: PURPOSE: A security wireless telephone having Bluetooth is provided to install Bluetooth in a body of a wireless telephone and a portable device, in order to enable a voice or a data speech mode, and to transmit digital code data up to a body of a wireless telephone and a portable device of the other party, thereby securing a call from wiretapping. CONSTITUTION: A wireless connection section between a portable device(102) and a wireless telephone body(106) is connected by Bluetooth units(100,103). The portable device(102) has an encoding function. The telephone body(106) has a data communication mode(105) except a telephone mode(104). When a user talks with a microphone of a handset(116) of the portable device(102), a voice is transmitted to the Bluetooth unit(103) of the body(106) through a voice channel. A voice signal received through the telephone mode(104) is transmitted to a circuit I/F(108) of a wireless telephone body(112) of the other party through a circuit I/F(107) and a network. The received voice is transmitted to a Bluetooth unit(113) through a voice channel of a Bluetooth unit(111), and is transmitted through a speaker of a handset(119).

Abstract: PURPOSE: A circuit for controlling a data transmission is provided to control a wait inter-exclusively upon transmitting data between two CPUs driven individually. CONSTITUTION: In a circuit for controlling a data transmission, the first signal comparing section(310) compares the write signal(WR_a) of the first CPU with the read signal(RD_b) of the second CPU to determine whether an error is generated or not upon transmitting data from the first CPU to the second CPU. The second signal comparing section(320) compares the write signal(WR_b) of the second CPU with the read signal(RD_a) of the first CPU to determine whether an error is generated or not upon transmitting data from the second CPU to the first CPU. A signal operation section(330) outputs a ready signal for controlling the continuous writing and reading operations in the first and second CPUs by operating the output signals of the first and second signal comparing sections.

Abstract: PURPOSE: An authentication method of a network system is provided to reduce authentication fail ratio by additionally transmitting a separate bit for displaying a fail period by a time deviation. CONSTITUTION: A bit flag is set when a difference between a client time and a representative value or a between a sum of an effective period and the representative value and the client time is smaller than a maximum time deviation. A subtracted value of the maximum time deviation from the client time is set as a client time. A client recognizing name, a password and the representative value are coded with a hash function. The coded value is transmitted with a recognizing name and the bit flag. A server time is set and a representative value is calculated by subtracting doubled value of the maximum time deviation from a server time. The coding is performed again by reading the password in the transmitted data. In conforming the coded values, an authentication is succeeded.

Abstract: PURPOSE: A tamper resistance device and a method for operating the same are provided to prevent data stored in a memory of an electronic device from being flowed out by an attack from an exterior or an illegal treatment. CONSTITUTION: An electronic device has a processor(114) which stores data in a memory(115) or reads/processes stored data. The electronic device is covered by an instrument(101). A luminous element(103) for emitting a light to an internal surface is included in the instrument(101). A light(109) emitted from the luminous element(103) is contacted with an internal surface(102) of the instrument(101) and the electronic device and dispersed to two-dimensional space or three-dimensional space. A partial portion of the dispersed light is collected in a light receiving element(111). An amount of a light collected to the light receiving element(111) is measured by a measuring device(112) and compared with a critical value in a comparator(113). In the case that the measured light amount is beyond tolerance, the comparator(113) outputs a predetermined signal to the processor(114). The processor(114) deletes data stored in the memory(115) in accordance with a signal from the comparator(113). The luminous element(103) is operated by a voltage being applied from an external power(107) or an internal power(106). If a level of the voltage become low or the power is stopped, a voltage comparison circuit(108) senses the variation and supplies a power from the internal power(106). A variable resistor(104) applies a power being supplied from the external power(107) or the internal power(106) to the luminous element(103) fixedly. The variable resistor(104) is controlled by a signal generated from a variable generator(105).
