Patent number: 5528247Abstract: The present invention relates to a mobile satellite communication system. It is the object of the invention to provide a mobile satellite communication system capable of monitoring a location of a mobile station by data on its absolute location on the ground L, in lieu of relative monitoring thereof with respect to satellite base stations, to thereby ensure an effective location registration and suppress an increase of traffic in communication lines arising from location registrations. The satellite base stations are each equipped with a navigation signal generator for issuing navigation signals. The mobile station detects its absolute location on the ground L based on the navigation signals received from the satellite base stations, and executes its location registration procedure by use of identification data (communication zone ID) associated with the communication zone in which it lies and which is determined by the thus detected absolute location data.Type: GrantFiled: June 7, 1994Date of Patent: June 18, 1996Assignee: Mitsubishi Denki Kabushiki KaishaInventor: Takayuki Nonami

Patent number: 5278866Abstract: A radio communication apparatus for transmitting and receiving a digital signal using a radio line which includes a memory means for storing a plurality of signal procedures in which each procedure has different ratio of the information code bits and error correction code bits.A signal processing circuit executes one of the procedures stored in the memory means according to line quality. Accordingly, the radio communication apparatus of the present invention selects the optimum procedure according to the line quality, and then reduces the consumed power.Type: GrantFiled: October 11, 1991Date of Patent: January 11, 1994Assignee: Mitsubishi Denki Kabushiki KaishaInventor: Takayuki Nonami

Patent number: 5251232Abstract: A radio communication apparatus used for both digital communications and analog communications is disclosed which comprises a digital signal processor DSP (4) which processes many kinds of digital signals according to a plurality of signal procedures (55,56,57,58) stored in the ROM (5). In the present invention, since the radio communication apparatus processes many kinds of procedures (55,56,57,58) stored in the ROM (5), the size of the apparatus becomes small and weight becomes light.Type: GrantFiled: November 12, 1991Date of Patent: October 5, 1993Assignee: Mitsubishi Denki Kabushiki KaishaInventor: Takayuki Nonami

Patent number: 5237592Abstract: Disclosed herein is a control device which is suitable for use in a radio communication apparatus employed in a radio communication system using a TDMA method. A timer circuit for circulating a counted value in a period corresponding to a period of time required to transmit a TDMA frame supplies the counted value to a strobe signal generating circuit. The strobe signal generating circuit supplies a strobe signal to a radio unit of the radio communication apparatus when a preset value coincides with the counted value of the timer circuit. Thus, since the strobe signal is generated without the intervention by a control circuit made up of a CPU or the like, it can be outputted in strict timing.Type: GrantFiled: March 12, 1991Date of Patent: August 17, 1993Assignee: Mitsubishi Denki Kabushiki KaishaInventor: Takayuki Nonami

Patent number: 5054052Abstract: A mobile telephone device comprises a separate paging signal channel in addition to the conventional transceiver channels which process voice signals. The paging signal channel has a lower power consumption level than the transceiver channels. A power supply control device shuts off power to the conventional transceiver channels when in a standby mode, i.e. when waiting for an incoming call, and applies power to the paging signal channel instead. Therefore, power consumption is reduced in the standby mode and consequently, the operating time of the battery is extended. Power is applied to the transceiver channels during voice communication periods. A calling party's telephone number received in the paging signal channel is stored and displayed. A control unit has the capability of immediately returning the calling party's call from the telephone number so stored and displayed.Type: GrantFiled: July 6, 1989Date of Patent: October 1, 1991Assignee: Mitsubishi Denki Kabushiki KaishaInventor: Takayuki Nonami

Patent number: 4819174Abstract: A road navigation system comprises a plurality of guidance information transmitter systems disposed along a route, each transmitter system generating current location information in the form of extremely-low-powered electric waves, and a guidance signal generator system for providing guidance information for the benefit of a user. The guidance signal generator system comprises a receiver unit for receiving the current location information from the guidance information transmitter system, an input unit for inputting destination information, a memory unit for storing available map information and the inputted destination information which can be prepared as route information to be traced, a data processor unit for comparing the route information with the current location information received by the receiver unit and for producing the guidance information, and an output unit for communicating the guidance information to the user.Type: GrantFiled: January 29, 1987Date of Patent: April 4, 1989Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Kenichi Furuno, Yoshio Tooko, Takayuki Nonami
