BEST MODE OF CARRYING OUT THE INVENTION With reference to the drawings, preferred embodiments of the present invention will be described. A. FIRST EMBODIMENT
Fig. 1 shows a configuration of a mobile telephone system 10 of first embodiment of the present invention. The service of this mobile telephone system is available to a number of mobile telephones. But, in order to simplify explanations, only mobile telephones 11 and. 13 are shown in Fig. 1, and explanations will be given of the service that the two mobile telephones receive. Also, term watch is used for wristwatch in this specification, claims, and drawings.
The mobile telephone system 10 includes a watch-shaped information processing device 12 that is used together with the mobile telephone 11. The watch-shaped information processing device 12 is one example of the radio communication devices of the present invention, and the mobile telephone 11 is one example of mobile telephones of the present invention. The watch-shaped information processmg device 12 performs bidirectional and local radio communication with the mobile telephone 11. The mobile telephone system 10 also has a mobile network 17 and a plurality of radio base stations 14 that are connected with the mobile network 17. The radio base station 14 estabfished a radio communication line with the mobile telephone 11 or 13. The mobile network 17 is connected with a public switched telephone network (PSTN) 16. Fixed telephones 15 and other equipment are connected with the PSTN 16. The mobile telephones 11 and 13 are able to communicate with each other via the mobile network 17. Also, the mobile telephones 11 and 13 are able to communicate with the fixed telephone 15 via the mobile network 17 and the PSTN 16.
Fig. 2 shows a configuration of a watch-shaped information processmg device 12 of the first embodiment. A transmitter circuit 24 in Fig. 2 conducts signal transmitting operation to the mobile telephone 11. A receiver circuit 23 in Fig. 2 conducts signal receiving operation from the mobile telephone 11. The transmitter circuit 24 (described later) has a circuit for generating oscillation signal SVCO. The oscillation signal SVCO is used for signal transnfitting operation in the transmitter circuit 24 and also is provided to the receiver circuit 23 for receiving operation. The frequency of the oscillation signal SVCO is defined by synthesizer control signal SSY output from a central control circuit 25. A switching circuit 22 switches an antenna unit 21 between to an input terminal of the receiver circuit 23 and to an output terminal of the transmitter circuit 24. In order for the watch-shaped information processmg device 12 to receive signals, the antenna unit 21 is connected to the input terminal of the receiver circuit 23 by the switching circuit 22. Then the receiver circuit 23 receives signals from the mobile telephone 11 via the antenna unit 21. Then, the receiver circuit 23 demodulates these signals into a received data DRX by using the oscillation signal SVCO to output to the central control circuit 25.
On the other hand, in order for the watch-shaped information processing device 12 to transmit signals, the antenna unit 21 is connected to the output terminal of the transmitter circuit 24. Then the transmitter circuit 24 receives a transmission data DTX from the central control circuit 25. The transmitter circuit 24 produces high frequency signal with a frequency designated by the synthesizer control signal SSY. The modulation of the high frequency signal is done based on the transmission data DTX. The transmitter circuit 24 sends the high frequency signal to the mobile telephone 11 via the antenna unit 21. The central control circuit 25 controls components of the watch-shaped information processing device 12, but detailed description of these controls will be given later.
Under the control of the central control unit 25, an electronic sound unit 26 produces electronic sound or buzzer sound to notify the user of states of the mobile telephone 11 or the watch-shaped information processing device 12. These states may be, for example, a device state such as calling state, call-receiving state, or error state. A vibrator 27 vibrates also under the control of the central control circuit 25 to notify the user of states of the mobile telephone 11 or the watch-shaped information processing device 12. A light emitting unit 28 has an LED or other light emitting device, and emits light under the control of the central control circuit 25 to notify the user of states of the mobile telephone 11 or the watch-shaped information processmg device 12. A display unit 29 is equipped with a liquid crystal display or an organic electroluminescence display, and displays information on states of the mobile telephone 11 or the watch-shaped information processing device 12 under the control of the central control circuit 25.
An external input unit 30 is equipped with buttons, a touch panel, and so on. Operating state of the external input unit 30 is checked by the central control circuit 25. A reference signal generator circuit 32 is connected with an oscillator 31, which generates a source oscillation signal having a reference frequency. The reference signal generator circuit 32 generates various reference signals to output to the central control circuit 25.
A nonvolatile memory 33 stores various data and programs. These data and programs are not lost even when power to the nonvolatile memory 33 is lost. The data stored in the nonvolatile memory 33 include a unique ID number NID for the watch-shaped information processing device 12 and another unique ID number NIDT for the mobile telephone 11 that is associated with the watch-shaped information processing device 12. The programs stored in the nonvolatile memory 33 include a control program that controls the watch-shaped information processing device 12 when, for example, there is an mcoming call to the mobile telephone 11. A central processing unit (CPU) in the central control circuit 25 functions as a controller unit of the radio communication devices of the present invention by executing the control programs stored in the nonvolatile memory 33.
A battery 34 supplies power to components of the watch-shaped information processing device 12.
A voice codec 38 decodes output signals of the central control circuit 25 to output voice data to a voice interface unit (voice I/F unit) 39. Also, the voice codec 38 encodes voice data from the voice interface unit 39 to output to the central control circuit 25.
The voice interface unit 39 performs digital-to-analog conversion on the voice data that is output by the voice codec 38 to output analog voice signal, then a speaker 35 outputs it. Also, the voice interface unit 39 performs analog-to-digital conversion on analog voice signals that are input via a microphone 36 to output voice data to the voice codec 38.
In this configuration, the receiver circuit 23 and the transmitter circuit 24 function as a transmitter-receiver unit of the radio communication device of the present invention. The central control circuit 25, the electronic sound unit 26, the vibrator 27, the fight emitter unit 28, and the display unit 29 function as an ήicoming-call-notification unit of the radio communication device of the present invention.
Fig. 3 shows a configuration of the antenna unit 21, the switching circuit 22, the receiver circuit 23, and the transmitter circuit 24 of the watch-shaped information processing device 12. As shown in Fig. 3, the antenna unit 21 is equipped with an antenna 21A and an antenna filter 21B. The antenna filter 21B eliminates unnecessary signal that may exist on the incoming signal and outputs only necessary signal to the receiver cfrcuit 23. The antenna filter 23 B also eliminates unnecessary signal that may exist on the output signal of the transmitter circuit 24 and outputs only necessary signal to the antenna 21A.
In the receiver circuit 23, an RF amplifier 23A amplifies the received signal of the antenna unit 21 to output to a mixer 23C. The mixer 23C is also provided with the oscillation signal SVCO from the transmitter circuit 24 via a buffer amplifier 23B. The mixer 23C then mixes these two signals and outputs to a bandpass filter 23D.
The bandpass filter 23D selects signal which has Intermediate Frequency (IF) from the output signals of the mixer 23C to output to an IF amplifier 23E. The IF amplifier 23E amplifies the signal with the IF to output to a demodulator cfrcuit 23F. While outputting the signal with the IF, the IF amplifier 23E outputs to the central control circuit 25 a signal strength signal SSS that indicates intensity of the received signal. The demodulator circuit 23F demodulates the signal with the IF into the received data DRX to the central control circuit 25.
In the transmitter circuit 24, a PLL circuit 24A, a low pass filter 24B, and a voltage controlled oscillator (VCO) 24E cooperate to generate the oscillation signal SVCO. The frequency of the oscillation signal SVCO is defined by the synthesizer control signal SSY. A modulator cfrcuit 24H modulates carrier using the transmission data
DTX to output signal which has IF. The signal with the IF is provided to a mixer 24G via an IF amplifier 24C and a low pass filter 24D. The mixer 24G mixes the signal with the IF and the oscillation signal SVCO to output high frequency signal. The high frequency signal is amplified by a power amplifier 24F and then provided to the antenna unit 21 via the switehing circuit 22.
Description of the antenna unit, the switehing circuit, the receiver circuit, and the transmitter circuit of the watch-shaped information processing device 12 was given above. The mobile telephone 11 also has the similar components in it. The antenna unit, the switehing cfrcuit, the receiver circuit, and the transmitter circuit of the mobile telephone 11 correspond to a transmitter-receiver unit of the mobile telephone of the present invention. Also, the central control cfrcuit (not shown in the figure) of the mobile telephone 11 that performs data communication using the above transmitter-receiver unit corresponds to a control unit of the mobile telephone of the present invention.
Fig. 4 is a sequence chart showing an operation of the first embodiment. With reference to the figure, the operation of the first embodiment will be described. At the initial state SI, the mobile telephone 11 periodically transmits an identification signal (which corresponds to the ID number NIND of the mobile telephone ll) having a synchronization signal using a carrier of 430 MHz or 2.45 GHz. On the other hand, the watch-shaped information processmg device 12 performs carrier sensing operation. As long as the watch-shaped information processing device 12 is receiving the identification signal from the mobile telephone 11, a synchronization of bidirectional communication exists between the watch- shaped information device 12 and the mobile telephone 11. When there is this synchronization and the watch-shaped information processing device 12 received from the mobile telephone 11 the identification signal that corresponds to the ID number NIND stored in the nonvolatile memory 33, the watch-shaped information processing device 12 can communicate with the mobile telephone 11. By this communication, the watch-shaped information processing device 12 can recognize the operating state of the mobile telephone 11.
Also at the initial state Si, as shown in Fig. 5, a date, day of the week, and a current time are shown on the display unit 29 of the watch-shaped information processing device 12. Also shown on the display unit 29 is a signal strength indicator SSI that tells strength of the received signal from the mobile telephone 11. The signal strength indicator SSI is displayed depending on the signal strength signal SSS output from the IF amplifier 23E of the receiver circuit 23. The reason to display the signal strength indicator SSI is to notify the user of quality deterioration or loss of radio corrimunication between the mobile telephone 11 and the watch-shaped information processing device 12.
There is an mcoming call to the mobile telephone 11 as shown in Fig. 4 (step S2). The incoming call may be, for example, from the fixed telephone 15 via the PSTN, the mobile network 17, and the radio base station 14, or from another mobile telephone 13 via the radio base station 14 and the mobile network 17. The mobile telephone 11 pages the watch-shaped information processing device 12 and sends information about the incoming call (step S5). In more detail, the mobile telephone 11 generates a send data DTXT that includes information to the effect that there is an incoming call, an ID number NID of the watch-shaped information processing device 12, and a telephone number of the caller. Then the mobile telephone 11 modulates carrier using the send data DTXT to output to the watch-shaped information processing device 12 an inrøming call notification signal which is a high frequency signal. As a circuit to generate a high frequency signal in the mobile telephone 11, a similar circuit to the transmitter circuit 24 in Fig. 3 is used.
In the watch-shaped information processing device 12, the incoming call notification signal is received in the antenna unit 21 and the receiver circuit 23 demodulates the incoming call notification signal to the received data DRX (step S6). This received data DRX includes information to the effect that there is an incoming call, an ID number NID of the watch-shaped information processing device 12, and a telephone number of the caller.
On receiving the received data DRX, the central control circuit 25 determines that there is an mcoming call to the mobile telephone 11, and then notifies user of mcoming call and displays information (step S7). In more detail, in order to notify the user of mcoming call, the central control cfrcuit 25 controls the electronic sound unit 26 to produce a buzzer sound or an electronic sound, the vibrator 27 to produce a vibration, or the light emitting unit 28 to blink light emitting device such as an LED. The central control circuit 25 also extracts the telephone number of the caller from the received data DRX, and displays on the display unit 29 the telephone number and other related information, if any information such as name of the caller is registered in advance. Fig. 6 shows the information for this case. Shown on the display unit 29 in Fig. 6 are the telephone number of the caller and a phrase meaning call incoming.
When the user notices an incoming call, s/he takes the mobile telephone 11 from the bag and makes a conversation. However, there is a case when the user cannot answer the incoming call. In that case, by the following operation, the user can send information telling that the user cannot answer the phone at the moment. The operation can be that the user operates buttons 30A, 30B, and 30C of the external input unit 30 to send instruction from the watch-shaped information processing device 12 to the mobile telephone 11 (steps S8 and S9). The instruction may be for sending a voice message that asks the caller to wait for a moment. When the mobile telephone 11 receives the instruction (step SlO), it answers the call automatically and makes a communication link. Then, the mobile telephone 11 reads an encoded data of voice message from an unshown nonvolatile memory. The voice message may be like "I am not able to answer the phone at the moment, please wait for a moment." Then the mobile telephone 11 sends the encoded data to the caller (step Sll).
By the first embodiment, when there is an incoming call to the mobile telephone, because the watch-shaped information processing device is notified of the incoming call, its user can recognize the incoming call and see caller's phone number without taking the mobile telephone from the bag. Also, when there is an incoming call, the user can ask the caller to wait for a moment by using the watch-shaped inform.ati.on processing device. It is also possible to configure the system to send text messages instead of voice messages. B. SECOND EMBODIMENT Fig. 7 shows a configuration of a mobile telephone HA of a mobile telephone system of the second embodiment.
The mobile telephone system of the second embodiment has similar configuration to that shown h Fig. 1. But the mobile telephone 11 is replaced with the mobile telephone HA and the watch-shaped information processing device 12 with the watch-shaped information processing device 12A.
In this mobile telephone system, when there is an mcoming call to the mobile telephone HA, the mobile telephone HA sends an incoming call notification signal to the watch-shaped information processing device 12A. Based on the incoming call notification signal, the watch-shaped information processing device 12A notifies the user of the incoming call. Also, the wateh-shaped information processmg device 12A sends an instruction signal to the mobile telephone HA based on user's instruction. In response to the instruction signal, the mobile telephone HA sends voice message to the caller via the mobile network 17. Next, with reference to Fig. 7, a configuration of the mobile telephone HA will be described.
As shown in Fig. 7, a bluetooth module 42 performs bidirectional communication with the watch-shaped information processing device 12A via an antenna 41 for bluetooth. A microprocessor 43 has a read only memory (ROM) and a random access memory (RAM) for storing various data. The microprocessor 43 controls communication, application, and entire units of the mobile telephone HA. Main control operation conducted by the microprocessor 43 are as follows; a control for sending an incoming call notification signal to the watch-shaped information processing device 12A when there is an incoming call, and a control for processing for inrønnng call.
An LCD driver 45 drives a liquid crystal display (LCD) 44 under a control of the microprocessor 43. An RF unit 47 conducts a high frequency signal processing such as am.plifying high frequency signal, and conducts a radio communication with mobile network via an antenna 46.
A W-CDMAbaseband processing unit 48 conducts baseband processing that is modulation/demodulation of the baseband signal for wide-band code division multiple access (W-CDMA).
A voice codec 49 decodes the output of the W-CDMA baseband processing unit 48 to output voice data and encodes voice data from a voice interface (IF) unit 52 to output to the W-CDMAbase band processing unit 48. The voice interface (IF) unit 52 conducts a digital-to-analog conversion on the voice data output from the voice codec 49 into analog voice signal, and voice sound is output from a speaker 50. The voice interface unit 52 also conducts a digital-to-analog conversion on analog signal input from a microphone 51 into a voice data, and the voice data is output to the voice codec 49. The external input unit 56 is equipped with various operation keys, an operation stick, a touch panel, and a jog dial, and operated by the user.
Next, configuration of the bluetooth module 42 will be described. An RF unit 54 of the bluetooth module 42 performs high frequency signal processing such as amplifying high frequency signal and performs bidirectional communication with the watch-shaped information processing device 12A.
A baseband processmg unit 55 modulates/demodulates baseband signals based on bluetooth technique.
Also, the bluetooth module 42 has a flash memory, a voltage regulator, a quartz oscillator, and other peripherals (all not shown). The configuration of this bluetooth module is already known.
The flash memory of the bluetooth module 42 stores various necessary information for bluetooth radio communication such as a bluetooth device address, a link key, and an encryption key. The bluetooth device address is used for identifying other bluetooth devices. The link key is used for authorizing radio communication when starting it. The encryption key is used for encrypted communication.
The bluetooth module 42 with the above configuration transmits, based on instructions from the microprocessor 43, to the watch-shaped information processing device 12A control data such as mcoming call notification signal that indicates there is an incoming call. This bluetooth module 42 also sends to the watch-shaped information processing device 12A voice data that is sent from other telephone via the mobile network 17. Also, the bluetooth module 42 receives various control data that are sent from the watch-shaped information processing device 12A, and outputs the received data to the microprocessor 43 and the W-CDMA base band processing unit 48 via a bus 53.
The wateh-shaped information processing device 12A carries out a synchronization establishment phase.
In this embodiment, either the watch-shaped information processing device 12A or the mobile telephone HA can be a master unit or a slave unit. The foUowing explanation is given with the assumption that the mobile telephone HA is a master unit and the watch-shaped information processing device 12Ais a slave unit.
At this time, a date, the day of the week, and a current time are displayed as shown in Fig. 5 on the display unit 29 of the watch-shaped information processing device 12A. Displayed also on the displayed unit 29 is the signal strength indicator SSI that shows an intensity of the received beacon signal periodically sent from the mobile telephone HA. This indicator is based on the above mentioned signal strength signal SSS.
The reason to display the signal strength indicator SSI is to tell the user of quality deterioration or loss of radio communication between the mobile telephone HA and the watch-shaped information processing device 12A.
When the user (referred to as a caller in this explanation) of the mobile telephone 13 in Fig. 1 calls the user of the mobile telephone HA, the mobile network 17 sends a teπ inating call signal via the radio base station 14. This terminating call signal includes telephone numbers of the mobile telephone HA and 13.
When the mobile telephone HA in a service area of the radio base station 14 receives the terminating call signal, the mobile telephone 11A conducts an communication connection with the wateh-shaped information processmg device 12A, a slave unit.
Then, the mobile telephone HA sends the incoming call notification signal in order to notify the incoming call. The mcoming call notification signal includes the caller's telephone number of the mobile telephone 13 and information to the effect that there is an incoming call.
When the watch-shaped ]tnformation processing device 12A receives the incoming call notification signal, it finds that there is an incoming call to the mobile telephone HA and displays information and notifies the user of incoming call. To illustrate, the watch-shaped information processing device 12A extracts the caller's telephone number from the ACL packets. Then the watch-shaped information processing device 12A displays on the display unit 29 telephone number or information corresponding to the telephone number to notify the user of the mcoming call. One example what is displayed on the display unit 29 in this case is shown in Fig.6. The watch-shaped information processing device 12A also performs the mcoming call notification.
When the user notices the mcoming call notification, the user has to take the mobile telephone HA from the bag to answer the call. However, there are some cases where the user cannot answer the call or the user cannot open the bag. In these cases, the user uses the external input unit 30 on the watch-shaped information processing device 12Afor instruction for "please wait message".
The watch-shaped information processing device 12A receives these inputs and sends to the mobile telephone 11 the instruction for "please wait message". When the mobile telephone HA receives the instruction for "please wait message", the mobile telephone HA orders the radio base station 14 to make a communication link with the caller's mobile telephone 13.
The radio base station 14 carries out a predetermined process such as for allocating a communication channel, and makes a commmiication fine between the mobile telephone HA and the mobile telephone 13.
When the mobile telephone HA receives an instruction for "please wait message" using the bluetooth module 42, the mobile telephone HA sends a pre- stored data for "please wait message" to the radio base station 14 using the W- CDMA base band processing unit 48, the RF unit 47, and the antenna 46.
The data for "please wait message" is received by the radio base station 14, and then is sent to the caller's mobile telephone 13 via the mobile network 17. Then the message is output from the speaker of the mobile telephone 13. The user of the mobile telephone 13 hears the message and waits for a moment or hangs up the phone.
Also, according to this embodiment, by using the watch-shaped information processing device 12A, the user can request the "please wait message" and a "call response message".
So, the watch-shaped information processing device 12A becomes an interesting gadget to its user.
