摘要： PROBLEM TO BE SOLVED: To provide a digital European cordless telecommunications DECT fixed part that provides a communication link between a DECT portable part and a global system for mobile communications GSM mobile exchange center. SOLUTION: The DECT fixed part receives a 1st message to designate a compression form for data service from either of a portable part and a mobile exchange center and decides a 2nd message to be sent to the other of the portable part and the mobile exchange center to make a request of adoption of a provision form of the compression of the data service by using the 1st message. Thus, a compression negotiation means is provided to conduct the compression data service between the portable part and the mobile exchange center.

摘要： PROBLEM TO BE SOLVED: To provide a method which estimates the DC offset and/or the phase offset of a radio receiver which can be operated in a digital pass band transmission system. SOLUTION: This estimating method samples a reception radio signal at the symbol rate of a transmission system to generate a set of data samples and processes each data sample included in this set of data samples for the purpose of determining a reception signal point' of each data sample in a signal space. Related group points of each reception signal point are determined in the signal space, and such DC offset and phase offset are calculated that the sum total of squares of errors between respective reception signal points and their related group points with respect to this set of data samples are reduced to a minimum limit.

摘要： PROBLEM TO BE SOLVED: To use a radio frequency circuit used for the reception of ground signals also for the reception of satellite signals by performing the frequency lowering conversion of first or second output signals and making a succeeding composite processing possibly by a mixing circuit. SOLUTION: An UHF synthesizer 603 supplies the output signals of the frequency range of 1545-1555MHz at the interval of 41.67kHz under the control of a microcontroller 405. Resultant first intermediate frequency signal are passed through a mode switch 607 and the mode switch 607 is switched to an IRIDIUM front end RF stage indicated by a broken line in the case of an IRIDIUM mode. Then, a second mixer 608 supplied with the local oscillator signals of 58MHz lowering-converts the first intermediate frequency signals and outputs the second intermediate frequency signals of 13MHz. The second intermediate frequency signals generated as a result are supplied to the base band part of a radio telephony equipment and supplied to the succeeding composite processing.

摘要： PROBLEM TO BE SOLVED: To permit a user to easily carry a part of the user interface of a radio telephone set and to easily maintain it in a place within his grasp by dividing the set into a first part and a second part and providing a data transfer means for executing communication between the first part and the second part. SOLUTION: The radio telephone set is divided into the first part (telephone part) 2 and the second part (wrist part) 3. The telephone part 2 is constituted of a power source, a radio part (transceiver) executing communication with a base station and the other radio telephone set in a radio telephone system, for example, an antenna 5 and the data transfer means for executing communication with the wrist part 3. The telephone part 2 has a link module 10 generating data transfer communication between the wrist part 3 and the telephone part 2. The wrist part 3 is constituted of a key and the data transfer means for making communication with the telephone part 2. Thus, the user can easily correspond to a telephone call by the key of the wrist part 3. Furthermore, the whole call can be executed by using only the wrist part 3.

摘要： PROBLEM TO BE SOLVED: To make call re-transmission to a ground communication line telephone number enable or disable automatically depending on a location of a mobile telephone set by detecting the presence of the mobile telephone set at a location. SOLUTION: A plurality of ground communication line telephone sets 8 and a ground communication line telephone set 1 via a ground communication line 6 are connected to a private branch of exchange (PBX) 3. The telephone set 1 is connected also to a call re-transmission means 4 provided to a desk top charger stand 5 via a wire. In the case of mounting a mobile telephone set 2 onto the charger stand 5, a battery of the mobile telephone set 2 is charged. A change in the charging state of the charger stand 5 indicates the presence/ absence of the mobile telephone set for the location. The call re-transmission means 4 starts and/or cancel call re-transmission to the mobile telephone set 2 of a call made to a ground communication line telephone number of the telephone set 1 in response to the change.

摘要： PROBLEM TO BE SOLVED: To provide a low-frequency amplitude modulator or a low-frequency phase modulator by using a controllable BAW(bulk acoustic wave) resonator, which shifts the resonance frequency according to the applied voltage. SOLUTION: A BAW resonator 102 consisting of a piezoelectric layer and protective layer electrodes, etc., is constructed on a substrate by means of a prescribed material and process. Then the resonator 102 is built into an amplitude modulation circuit 91 as a modulator. When the modulating low-frequency signal, which is produced by an oscillator 96 is filtered by an LPF 98 and an RF choke 100 and applied between the electrodes 102a and 102b of the resonator 102, an electric field is generated on a piezoelectric layer 102c and vibration time-wise varying according to the signals is produced. A prescribed RF carrier signal that is produced by an oscillator 90 is filtered and applied to the resonator 102. The carrier signal is attenuated by the resonance frequency, as well as the impedance caused by the low-frequency signal of the resonator 102. Then the amplitude modulation is carried out. In a phase modulation mode, the oscillation frequency of the oscillator 90 is set almost equal to the parallel resonance frequency of the resonator 102. Then the phase shift is carried out.

摘要： PROBLEM TO BE SOLVED: To uniform the consumption of the memory of a flash memory by detecting an area used beyond a prescribed threshold value as a first memory area, and storing an electronic signal corresponding to an electronic signal indicating parameter data stored in the first memory area in a second memory area. SOLUTION: This device is provided with a stage for detecting plural used memory areas beyond a prescribed threshold value as a first memory area, a stage for deciding a second memory area which can be used for storing an electronic signal, and a stage for storing an electronic signal corresponding to the electronic signal indicating parameter data stored in the first memory area in the second memory area. For example, in a microcontroller 200 of a radio telephone 214, a flash memory manager applies a pair of instructions to a CPU 202 for applying a means for uniformly re-using the flash memory block. Then, all the memories can be uniformly consumed.

摘要： PROBLEM TO BE SOLVED: To transfer full duplex real time audio by the half duplex IR link of a low speed by using an appropriate system and switching the direction of a half duplex channel. SOLUTION: An IR link module 10 is provided with the combination of a plurality of functional blocks 11-15 and a medium driver as an IR block 16 and is provided with three link interfaces with it. The IR link module 10 is connected to the BB of a mobile telephone or the like through a BBIF and transmits signals from there through an MIF and an IRIF to the free space of the outside or a light guide. A multiplexer 13 is controlled by the state machine of a control block 12 and selects a bit correct number from FIFOs 14 and 15. At the high-speed bus mode, the multiplexer 13 specifies the route of a high-speed bus message so as to directly reach the IR block 16 from a high-speed data channel 19.
