     DETAILED DESCRIPTION 
     The following description is of the best presently contemplated mode of carrying out the present invention. This description is not to be taken in a limiting sense but is made merely for the purpose of describing the general principles of the invention. For example, each description of random access memory in this specification illustrates only one function or mode in order to avoid complexity in its explanation, however, such description does not mean that only one function or mode can be implemented at a time. In other words, more than one function or mode can be implemented simultaneously by way of utilizing the same random access memory. In addition, the figure numbers are cited after the elements in parenthesis in a manner for example ‘RAM  206  (FIG.  1 )’. It is done so merely to assist the readers to have a better understanding of this specification, and must not be used to limit the scope of the claims in any manner since the figure numbers cited are not exclusive. There are only few data stored in each storage area described in this specification. This is done so merely to simplify the explanation and, thereby, to enable the reader of this specification to understand the content of each function with less confusion. Therefore, more than few data (hundreds and thousands of data, if necessary) of the same kind, not to mention, are preferred to be stored in each storage area to fully implement each function described herein. The scope of the invention should be determined by referencing the appended claims.

     When Communication Device  200  is in the voice communication mode, the analog audio data input to Microphone  215  is converted to a digital format by A/D  213  and transmitted to another device via Antenna  218  in a wireless fashion after being processed by Signal Processor  208 , and the wireless signal representing audio data which is received via Antenna  218  is output from Speaker  216  after being processed by Signal Processor  208  and converted to analog signal by D/A  204 . For the avoidance of doubt, the definition of Communication Device  200  in this specification includes so-called ‘PDA’. The definition of Communication Device  200  also includes in this specification any device which is mobile and/or portable and which is capable to send and/or receive audio data, text data, image data, video data, and/or other types of data in a wireless fashion via Antenna  218 . The definition of Communication Device  200  further includes any micro device embedded or installed into devices and equipments (e.g., VCR, TV, tape recorder, heater, air conditioner, fan, clock, micro wave oven, dish washer, refrigerator, oven, washing machine, dryer, door, window, automobile, motorcycle, and modem) to remotely control these devices and equipments. The size of Communication Device  200  is irrelevant. Communication Device  200  may be installed in houses, buildings, bridges, boats, ships, submarines, airplanes, and spaceships, and firmly fixed therein.

The voice recognition function can be performed in terms of software by using Area  261 , the voice recognition working area, of RAM  206  ( FIG. 1 ) which is specifically allocated to perform such function as described in  FIG. 3 , or can also be performed in terms of hardware circuit where such space is specifically allocated in Area  282  of Sound Processor  205  ( FIG. 1 ) for the voice recognition system as described in  FIG. 4 . 
       FIG. 5  illustrates how the voice recognition function is activated. CPU  211  ( FIG. 1 ) periodically checks the input status of Input Device  210  ( FIG. 1 ) (S 1 ). If the CPU  211  detects a specific signal input from Input Device  210  (S 2 ) the voice recognition system which is described in  FIG. 2  and/or  FIG. 3  is activated. As another embodiment, the voice recognition system can also be activated by entering predetermined phrase, such as ‘start voice recognition system’ via Microphone  215  ( FIG. 1 ). 
     &lt;&lt;Voice Recognition—Dialing/Auto-Off During Call Function&gt;&gt; 
       FIG. 6   a  and  FIG. 6   b  illustrate the operation of the voice recognition in the present invention. Once the voice recognition system is activated (S 1 ) the analog audio data is input from Microphone  215  ( FIG. 1 ) (S 2 ). The analog audio data is converted into digital data by A/D  213  ( FIG. 1 ) (S 3 ). The digital audio data is processed by Sound Processor  205  ( FIG. 1 ) to retrieve the text and numeric information therefrom (S 4 ). Then the numeric information is retrieved (S 5 ) and displayed on LCD  201  ( FIG. 1 ) (S 6 ). If the retrieved numeric information is not correct (S 7 ), the user can input the correct numeric information manually by using Input Device  210  ( FIG. 1 ) (S 8 ). Once the sequence of inputting the numeric information is completed and after the confirmation process is over (S 9 ), the entire numeric information is displayed on LCD  201  and the sound is output from Speaker  216  under control of CPU  211  (S 10 ). If the numeric information is correct (S 11 ), Communication Device  200  ( FIG. 1 ) initiates the dialing process by utilizing the numeric information (S 12 ). The dialing process continues until Communication Device  200  is connected to another device (S 13 ). Once CPU  211  detects that the line is connected it automatically deactivates the voice recognition system (S 14 ). 
     As described in  FIG. 7 , CPU  211  ( FIG. 1 ) checks the status of Communication Device  200  periodically (S 1 ) and remains the voice recognition system offline during call (S 2 ). If the connection is severed, i.e., user hangs up, then CPU  211  reactivates the voice recognition system (S 3 ). 
     &lt;&lt;Voice Recognition Tag Function&gt;&gt; 
       FIGS. 8 through 12  describes the method of inputting the numeric information in a convenient manner. 
     As described in  FIG. 8 , RAM  206  includes Table # 1  ( FIG. 8 ) and Table # 2  ( FIG. 9 ). In  FIG. 8 , audio information # 1  corresponds to tag ‘Scott.’ Namely audio information, such as wave data, which represents the sound of ‘Scott’ (sounds like ‘S-ko-t’) is registered in Table # 1 , which corresponds to tag ‘Scott’. In the same manner audio information # 2  corresponds to tag ‘Carol’; audio information # 3  corresponds to tag ‘Peter’; audio information # 4  corresponds to tag ‘Amy’; and audio information # 5  corresponds to tag ‘Brian.’ In  FIG. 9 , tag ‘Scott’ corresponds to numeric information ‘(916) 411-2526’; tag ‘Carol’ corresponds to numeric information ‘(418) 675-6566’; tag ‘Peter’ corresponds to numeric information ‘(220) 890-1567’; tag ‘Amy’ corresponds to numeric information ‘(615) 125-3411’; and tag ‘Brian’ corresponds to numeric information ‘(042) 645-2097.’ FIG. 11  illustrates how CPU  211  ( FIG. 1 ) operates by utilizing both Table # 1  and Table # 2 . Once the audio data is processed as described in S 4  of  FIG. 6 , CPU  211  scans Table # 1  (S 1 ). If the retrieved audio data matches with one of the audio information registered in Table # 1  (S 2 ), CPU  211  scans Table # 2  (S 3 ) and retrieves the corresponding numeric information from Table # 2  (S 4 ). 
       FIG. 10  illustrates another embodiment of the present invention. Here, RAM  206  includes Table #A instead of Table # 1  and Table # 2  described above. In this embodiment, audio info # 1  (i.e., wave data which represents the sound of ‘Scot’) directly corresponds to numeric information ‘(916) 411-2526.’ In the same manner audio info # 2  corresponds to numeric information ‘(410) 675-6566’; audio info # 3  corresponds to numeric information ‘(220) 890-1567’; audio info # 4  corresponds to numeric information ‘(615) 125-3411’; and audio info # 5  corresponds to numeric information ‘(042) 645-2097.’ FIG. 12  illustrates how CPU  211  ( FIG. 1 ) operates by utilizing Table #A. Once the audio data is processed as described in S 4  of  FIG. 6 , CPU  211  scans Table #A (S 1 ). If the retrieved audio data matches with one of the audio information registered in Table #A (S 2 ), it retrieves the corresponding numeric information therefrom (S 3 ). 
     As another embodiment, RAM  206  may contain only Table # 2  and tag can be retrieved from the voice recognition system explained in  FIGS. 3 through 7 . Namely, once the audio data is processed by CPU  211  ( FIG. 1 ) as described in S 4  of  FIG. 6  and retrieves the text data therefrom and detects one of the tags registered in Table # 2  (e.g., ‘Scot’), CPU  211  retrieves the corresponding numeric information (e.g., ‘(916) 411-2526’) from the same table. 
     &lt;&lt;Voice Recognition Noise Filtering Function&gt;&gt; 
       FIGS. 13 through 15  describes the method of minimizing the undesired effect of the background noise when utilizing the voice recognition system. 
     As described in  FIG. 13 , RAM  206  ( FIG. 1 ) includes Area  255  and Area  256 . Sound audio data which represents background noise is stored in Area  255 , and sound audio data which represents the beep, ringing sound and other sounds which are emitted from the Communication Device  200  are stored in Area  256 . 
       FIG. 14  describes the method to utilize the data stored in Area  255  and Area  256  described in  FIG. 13 . When the voice recognition system is activated as described in  FIG. 5 , the analog audio data is input from Microphone  215  ( FIG. 1 ) (S 1 ). The analog audio data is converted into digital data by A/D  213  ( FIG. 1 ) (S 2 ). The digital audio data is processed by Sound Processor  205  ( FIG. 1 ) (S 3 ) and compared to the data stored in Area  255  and Area  256  (S 4 ). Such comparison can be done by either Sound Processor  205  or CPU  211  ( FIG. 1 ). If the digital audio data matches to the data stored in Area  255  and/or Area  256 , the filtering process is initiated and the matched portion of the digital audio data is deleted as background noise. Such sequence of process is done before retrieving text and numeric information from the digital audio data. 
       FIG. 14   a  describes the method of updating Area  255 . When the voice recognition system is activated as described in  FIG. 5 , the analog audio data is input from Microphone  215  ( FIG. 1 ) (S 1 ). The analog audio data is converted into digital data by A/D  213  ( FIG. 1 ) (S 2 ). The digital audio data is processed by Sound Processor  205  ( FIG. 1 ) or CPU  211  ( FIG. 1 ) (S 3 ) and the background noise is captured (S 4 ). CPU  211  ( FIG. 1 ) scans Area  255  and if the captured background noise is not registered in Area  255 , it updates the sound audio data stored therein (S 5 ). 
       FIG. 15  describes another embodiment of the present invention. CPU  211  ( FIG. 1 ) routinely checks whether the voice recognition system is activated (S 1 ). If the system is activated (S 2 ), the beep, ringing sound, and other sounds which are emitted from Communication Device  200  are automatically turned off in order to minimize the miss recognition process of the voice recognition system (S 3 ). 
     &lt;&lt;Voice Recognition Auto-Off Function&gt;&gt; 
     The voice recognition system can be automatically turned off to avoid glitch as described in  FIG. 16 . When the voice recognition system is activated (S 1 ), CPU  211  ( FIG. 1 ) automatically sets a timer (S 2 ). The value of timer (i.e., the length of time until the system is deactivated) can be set manually by the user. The timer is incremented periodically (S 3 ), and if the incremented time equals to the predetermined value of time as set in S 2  (S 4 ), the voice recognition system is automatically deactivated (S 5 ). 
     &lt;&lt;Voice Recognition Email Function (1)&gt;&gt; 
       FIGS. 17   a  and  17   b  illustrate the first embodiment of the function of typing and sending e-mails by utilizing the voice recognition system. Once the voice recognition system is activated (S 1 ), the analog audio data is input from Microphone  215  ( FIG. 1 ) (S 2 ). The analog audio data is converted into digital data by A/D  213  ( FIG. 1 ) (S 3 ). The digital audio data is processed by Sound Processor  205  ( FIG. 1 ) or CPU  211  ( FIG. 1 ) to retrieve the text and numeric information therefrom (S 4 ). The text and numeric information are retrieved (S 5 ) and are displayed on LCD  201  ( FIG. 1 ) (S 6 ). If the retrieved information is not correct (S 7 ), the user can input the correct text and/or numeric information manually by using the Input Device  210  ( FIG. 1 ) (S 8 ). If inputting the text and numeric information is completed (S 9 ) and CPU  211  detects input signal from Input Device  210  to send the e-mail (S 10 ), the dialing process is initiated (S 11 ). The dialing process is repeated until Communication Device  200  is connected to Host H (S 12 ), and the e-mail is sent to the designated address (S 13 ). 
     &lt;&lt;Voice Recognition—Speech-to-Text Function&gt;&gt; 
       FIG. 18  illustrates the speech-to-text function of Communication Device  200  ( FIG. 1 ). 
     Once Communication Device  200  receives a transmitted data from another device via Antenna  218  ( FIG. 1 ) (S 1 ), Signal Processor  208  ( FIG. 1 ) processes the data (e.g., wireless signal error check and decompression) (S 2 ), and the transmitted data is converted into digital audio data (S 3 ). Such conversion can be rendered by either CPU  211  ( FIG. 1 ) or Signal Processor  208 . The digital audio data is transferred to Sound Processor  205  ( FIG. 1 ) via Data Bus  203  and text and numeric information are retrieved therefrom (S 4 ). CPU  211  designates the predetermined font and color to the text and numeric information (S 5 ) and also designates a tag to such information (S 6 ). After these tasks are completed the tag and the text and numeric information are stored in RAM  206  and displayed on LCD  201  (S 7 ). 
       FIG. 19  illustrates how the text and numeric information as well as the tag are displayed. On LCD  201  the text and numeric information  702  (‘XXXXXXXXX’) are displayed with the predetermined font and color as well as with the tag  701  (‘John’).

Relays R 1  through R 20  are preferably located on ground, however, are also permitted to be installed in artificial satellites as described in the foregoing patents and the references cited thereof in order to cover wider geographical range. The Relays may also be installed in houses, buildings, bridges, boats, ships, submarines, airplanes, and spaceships. In addition, Host H may be carried by houses, buildings, bridges, boats, ships, submarines, airplanes, and spaceships. In stead of utilizing Cables C 1  through C 5 , Relays R 1  through R 20  (and other relays described in this specification) may be connected to Transmitter T in a wireless fashion, and Transmitter T may be connected to Host H in a wireless fashion. 
       FIGS. 21 through 26  illustrate how the positioning system is performed. Assuming that Device A, Communication Device  200 , seeks to detect the position of Device B, another Communication Device  200 , which is located somewhere in the matrix of Relays illustrated in  FIG. 20   b.    
     As described in  FIG. 21 , first of all the device ID of Device B is entered by utilizing Input Device  210  ( FIG. 1 ) or the voice recognition system of Device A installed therein (S 1 ). The device ID may be its corresponding phone number. A request data including the device ID is sent to Host H ( FIG. 20   a ) from Device A (S 2 ). 
     As illustrated in  FIG. 22 , Host H ( FIG. 20   a ) periodically receives data from Device A (S 1 ). If the received data is a request data (S 2 ), Host H, first of all, searches its communication log which records the location of Device B when it last communicated with Host H (S 3 ). Then Host H sends search signal from the Relays described in  FIG. 20   b  which are located within 100-meter radius from the location registered in the communication log. If there is no response from Device B (S 5 ), Host H sends a search signal from all Relays (from R 1  to R 20  in  FIG. 20   b ) (S 6 ). 
     As illustrated in  FIG. 23 , Device B periodically receives data from Host H ( FIG. 20   a ) (S 1 ). If the data received is a search signal (S 2 ), Device B sends a response signal to Host H (S 3 ). 
     As illustrated in  FIG. 24  Host H ( FIG. 20   a ) periodically receives data from Device B (S 1 ). If the data received is a response signal (S 2 ), Host H locates the geographic position of Device B by utilizing the method described in  FIGS. 20   a  and  20   b  (S 3 ), and sends the location data and the relevant map data of the area where Device B is located to Device A (S 4 ). 
     As illustrated in  FIG. 25 , Device A periodically receives data from Host H ( FIG. 20   a ) (S 1 ). If the data received is the location data and the relevant map data mentioned above (S 2 ), Device A displays the map based on the relevant map data and indicates the current location of Device B thereon based on the location data received (S 3 ). 
     Device A can continuously track down the current location of Device B as illustrated in  FIG. 26 . First, Device A sends a request data to Host H ( FIG. 20   a ) (S 1 ). As soon as Host H receives the request data (S 2 ), it sends a search signal in the manner illustrated in  FIG. 22  (S 3 ). As soon as Device B receives the search signal (S 4 ), it sends a response signal to Host H (S 5 ). Based on the response signal, Host H locates the geographic location of Device B with the method described in  FIGS. 20   a  and  20   b  (S 6 ). Then Host H sends to Device A a renewed location data and a relevant map data of the area where Device B is currently located (S 7 ). As soon as these data are received (S 8 ), Device A displays the map based on the relevant map data and indicates the updated location based on the renewed location data (S 9 ). If Device B is still within the specified area Device A may use the original relevant map data. As another embodiment of the present invention, S 1  through S 4  may be omitted and make Device B send a response signal continuously to Host H until Host H sends a command signal to Device B to cease sending the response signal. 
     &lt;&lt;Positioning System—Automatic Silent Mode&gt;&gt; 
       FIGS. 27   a  through  32   g  illustrate the automatic silent mode of Communication Device  200  ( FIG. 1 ). 
     In  FIG. 27   a , Relay R 1  is connected to Cable C 1 , Relay R 2  is connected to Cable C 2 , Relay R 3  is connected to Cable C 3 , and Relay R 4  is connected to Cable C 4 . Cables C 1 , C 2 , C 3 , and C 4  are connected to Transmitter T, which is connected to Host H by Cable C 5 . The Relays (R 1  through R  20 ) are located throughout the predetermined area in the pattern illustrated in  FIG. 27   b . The system illustrated in  FIGS. 27   a  and  27   b  is designed to pinpoint the position of Communication Device  200  by using the method so-called ‘global positioning system’ or ‘GPS.’ As stated hereinbefore, such function can be enabled by the technologies primarily introduced in the inventions in the foregoing patents and the references cited thereof. The Relays R 1  through R 20  are preferably located on ground, however, are also permitted to be installed in artificial satellites as described in the foregoing patents and the references cited thereof in order to cover wider geographical range. In addition, Host H may be carried by an artificial satellite and utilize the formation as described in  FIGS. 2   a ,  2   b , and  2   c.    
     As illustrated in  FIG. 28 , the user of Communication Device  200  may set the silent mode by Input Device  210  ( FIG. 1 ) or by utilizing the voice recognition system installed therein. When Communication Device  200  is in the silent mode, (a) the ringing sound is turned off, (b) Vibrator  217  ( FIG. 1 ) activates when Communication Device  200  receives call, and/or (c) Communication Device  200  sends an automatic response to the caller device when a call is received (S 1 ). The user may, at his discretion, select any of these predetermined functions of the automatic silent mode. 
       FIG. 29  illustrates how the automatic silent mode is activated. Communication Device  200  periodically checks its present location with the method so-called ‘global positioning system’ or ‘GPS’ by using the system illustrated in  FIGS. 27   a  and  27   b  (S 1 ). Communication Device  200  then compares the present location and the previous location (S 2 ). If the difference of the two values is more than the specified amount X, i.e., when the moving velocity of Communication Device  200  exceeds the predetermined value (S 3 ), the silent mode is activated and (a) the ringing sound is automatically turned off, (b) Vibrator  217  ( FIG. 1 ) activates, and/or (c) Communication Device  200  sends an automatic response to the caller device according to the user&#39;s setting (S 4 ). Here, the silent mode is automatically activated because the user of Communication Device  200  is presumed to be on an automobile and is not in a situation to freely answer the phone, or the user is presumed to be riding a train and does not want to disturb other passengers. 
     As another embodiment of the present invention, the automatic silent mode may be administered by Host H ( FIG. 27   a ). As illustrated in  FIG. 30 , the silent mode is set in the manner described in  FIG. 28  (S 1 ) and Communication Device  200  sends to Host H a request signal indicating that it is in the silent mode (S 2 ). 
     As described in  FIG. 31 , when Host H ( FIG. 27   a ) detects a call to Communication Device  200  after receiving the request signal, it checks the current location of Communication Device  200  (S 1 ) and compares it with the previous location (S 2 ). If the difference of the two values is more than the specified amount X, i.e., when the moving velocity of Communication Device  200  exceeds the predetermined value (S 3 ), Host H sends a notice signal to Communication Device  200  indicating that it has received an incoming call (S 4 ). 
     As illustrated in  FIG. 32 , Communication Device  200  receives data periodically from Host H ( FIG. 27   a ) (S 1 ). If the received data is a notice signal (S 2 ), Communication Device  200  activates the silent mode (S 3 ) and (a) the ringing sound is automatically turned off, (b) Vibrator  217  ( FIG. 1 ) activates, and/or (c) Communication Device  200  sends an automatic response to the caller device according to the user&#39;s setting. The automatic response may be sent from Host H instead. 
     As another embodiment of the present invention, a train route data may be utilized. As illustrated in  FIG. 32   a , a train route data is stored in Area  263  of RAM  206 . The train route data contains three-dimensional train route map including the location data of the train route.  FIG. 32   b  illustrates how the train route data is utilized. CPU  211  ( FIG. 1 ) periodically checks the present location of Communication Device  200  by the method described in  FIGS. 27   a  and  27   b  (S 1 ). Then CPU  211  compares with the train route data stored in Area  263  of RAM  206  (S 2 ). If the present location of Communication Device  200  matches the train route data (i.e., if Communication Device  200  is located on the train route) (S 3 ), the silent mode is activated in the manner described above (S 4 ). The silent mode is activated because the user of Communication Device  200  is presumed to be currently on a train and may not want to disturb the other passengers on the same train. 
     As another embodiment of the present invention, such function can be delegated to Host H ( FIG. 27   a ) as described in  FIG. 32   c . Namely, Host H ( FIG. 27   a ) periodically checks the present location of Communication Device  200  by the method described in  FIGS. 27   a  and  27   b  (S 1 ). Then Host H compares the present location with the train route data stored in its own storage (not shown) (S 2 ). If the present location of communication  200  matches the train route data (i.e., if Communication Device  200  is located on the train route) (S 3 ) Host H sends a notice signal to Communication Device  200  thereby activating the silent mode in the manner described above (S 4 ). 
     Another embodiment is illustrated in  FIGS. 32   f  and  32   g . As illustrated in  FIG. 32   f , Relays R  101 , R  102 , R  103 , R  104 , R  105 , R  106 , which perform the same function to the Relays described in  FIG. 27   a  and  FIG. 27   b , are installed in Train Tr. The signals from these Relays are sent to Host H illustrated in  FIG. 27   a . Relays R  101  through R  106  emit inside-the-train signals which are emitted only inside Train Tr.  FIG. 32   g  illustrates how Communication Device  200  operates inside Train Tr. Communication Device  200  periodically checks the signal received in Train Tr (S 1 ). If Communication Device  200  determines that the signal received is an inside-the-train signal (S 2 ), it activates the silent mode in the manner described above (S 3 ). 
     &lt;&lt;Positioning System—Auto Response Mode&gt;&gt; 
       FIG. 32   d  and  FIG. 32   e  illustrates the method to send an automatic response to a caller device when the silent mode is activated. 
     Assume that the caller device, a Communication Device  200 , intends to call a callee device, another Communication Device  200  via Host H ( FIG. 27   a ). As illustrated in  FIG. 32   d , the caller device dials the callee device and the dialing signal is sent to Host H (S 1 ). Host H checks whether the callee device is in the silent mode (S 2 ). If Host H detects that the callee device is in the silent mode, it sends a predetermined auto response which indicates that the callee is probably on a train and may currently not be available, which is received by the caller device (S 3 ). If the user of the caller device still desires to request for connection and certain code is input from Input Device  210  ( FIG. 1 ) or by the voice recognition system (S 4 ), a request signal for connection is sent and received by Host H (S 5 ), and the line is connected between the caller device and the callee device via Host H (S 6 ). 
     As another embodiment of the present invention, the task of Host H ( FIG. 27   a ) which is described in  FIG. 32   d  may be delegated to the callee device as illustrated in  FIG. 32   e . The caller device dials the callee device and the dialing signal is sent to the callee device via Host H (S 1 ). The callee device checks whether it is in the silent mode (S 2 ). If the callee device detects that it is in the silent mode, it sends an predetermined auto response which indicates that the callee is probably on a train and may currently not be available, which is sent to the caller device via Host H (S 3 ). If the user of the caller device still desires to request for connection and certain code is input from Input Device  210  ( FIG. 1 ) or by the voice recognition system (S 4 ), a request signal for connection is sent to the callee device via Host H (S 5 ), and the line is connected between the caller device and the callee device via Host H (S 6 ).

First of all, a timer (not shown) is set by a specific input signal produced by Input Device  210  ( FIG. 1 ) or by the voice recognition system (S 1 ). The timer is incremented periodically (S 2 ) and when the incremented value equals the predetermined value (S 3 ), CPU  211  ( FIG. 1 ) initiates the dialing process (S 4 ). The dialing process continues until Communication Device  200  is connected to Host H explained in  FIG. 37  (S 5 ). Once the line is connected, CPU  211  reads the information stored in Area  264  (S 6 ) and based on such information it initiates to transfer the selected data from RAM  206  to Host H (S 7 ). The transfer continues until all of the selected data are transferred to Host H (S 8 ), and the line is disconnected thereafter (S 9 ). This backup sequence can be initiated automatically and periodically by using a timer or manually.

     &lt;&lt;Timer Email Function&gt;&gt; 
       FIGS. 53   a  and  53   b  illustrate the method of sending emails from Communication Device  200  ( FIG. 1 ) by utilizing a timer. 
     Address data, i.e., email address is input by utilizing Input Device  210  ( FIG. 1 ) or via voice recognition system explained in  FIG. 3 ,  FIG. 4 ,  FIG. 5 ,  FIG. 13 ,  FIG. 14 ,  FIG. 14   a ,  FIG. 15 ,  FIG. 16  and/or  FIG. 17  (S 1 ) and the text data, the text of the email message is input by the same manner (S 2 ). The address data and the text data are automatically saved in RAM  206  ( FIG. 1 ) (S 3 ). The sequence of S 1  through S 3  is repeated (i.e., writing more than one email) until a specified input signal is input from Input Device  210  ( FIG. 1 ) or by utilizing the voice recognition system explained above. Once inputting both the address data and the text data (which also includes numeric data, images and programs) are completed a timer (not shown) is set by Input Device  210  or by utilizing the voice recognition system (S 5 ), and the timer is incremented periodically (S 6 ) until the timer value equals the predetermined value specified in S 5  (S 7 ). A dialing process is continued (S 8 ) until the line is connected (S 9 ) and the text data are sent thereafter to email addresses specified in S 1  (S 10 ). All of the emails are sent (S 11 ) and the line is disconnected thereafter (S 12 ). 
     As another embodiment of the present invention a specific time may be input by Input Device  210  and send the text data on the specific time (i.e., a broad meaning of ‘timer’).

     A communication device comprising a text data input means which inputs one or more text data, a storage means which stores said text data, a sending means which sends said text data which is input by said input means, and a timer means which activates said sending means at a predetermined time wherein said text data input means input said text data, said storage means stores said text data input by said text data input means, said timer means activates said sending means at said predetermined time, and said sending means sends said text data at said predetermined time thereby enabling the user of said communication device to send said text data at said predetermined time at which said user is not able to send said text data. 
     &lt;&lt;Call Blocking Function&gt;&gt; 
       FIGS. 54 through 56  illustrates the so-called ‘call blocking’ function of Communication Device  200  ( FIG. 1 ). 
     As illustrated in  FIG. 54 , RAM  206  ( FIG. 1 ) includes Area  273  and Area  274 . Area  273  stores phone numbers that should be blocked. In the example illustrated in  FIG. 54 , Phone # 1 , Phone # 2 , and Phone # 3  are blocked. Area  274  stores a message data, preferably a wave data, stating that the phone can not be connected. 
       FIG. 55  illustrates the operation of Communication Device  200 . When Communication Device  200  receives a call (S 1 ), CPU  211  ( FIG. 1 ) scans Area  273  ( FIG. 54 ) of RAM  206  (S 2 ). If the phone number of the incoming call matches one of the phone numbers stored in Area  273  (S 3 ), CPU  211  sends the message data stored in Area  274  ( FIG. 54 ) of RAM  206  to the caller device (S 4 ) and disconnects the line (S 5 ). 
       FIG. 56  illustrates the method of updating Area  273  ( FIG. 54 ) of RAM  206 . Assuming that the phone number of the incoming call does not match any of the phone numbers stored in Area  273  of RAM  206  (see S 3  of  FIG. 55 ). In that case, Communication Device  200  is connected to the caller device. However, the user of Communication Device  200  may decide to have such number ‘blocked’ after all. If that is the case, the user dials ‘999’ while the line is connected. Technically CPU  211  ( FIG. 1 ) periodically checks the signals input from Input Device  210  ( FIG. 1 ) (S 1 ). If the input signal represents a numerical data ‘999’ from Input Device  210  (S 2 ), CPU  211  adds the phone number of the pending call to Area  273  (S 3 ) and sends the message data stored in Area  274  ( FIG. 54 ) of RAM  206  to the caller device (S 4 ). The line is disconnected thereafter (S 5 ). 
       FIGS. 57 through 59  illustrate another embodiment of the present invention. 
     As illustrated in  FIG. 57 , Host H (not shown) includes Area  403  and Area  404 . Area  403  stores phone numbers that should be blocked to be connected to Communication Device  200 . In the example illustrated in  FIG. 57 , Phone # 1 , Phone # 2 , and Phone # 3  are blocked for Device A; Phone # 4 , Phone # 5 , and Phone # 6  are blocked for Device B; and Phone # 7 , Phone # 8 , and Phone # 9  are blocked for Device C. Area  404  stores a message data stating that the phone can not be connected. 
       FIG. 58  illustrates the operation of Host H (not shown). Assuming that the caller device is attempting to connect to Device B, Communication Device  200 . Host H periodically checks the signals from all Communication Device  200  (S 1 ). If Host H detects a call for Device B (S 2 ), it scans Area  403  ( FIG. 57 ) (S 3 ) and checks whether the phone number of the incoming call matches one of the phone numbers stored therein for Device B (S 4 ). If the phone number of the incoming call does not match any of the phone numbers stored in Area  403 , the line is connected to Device B (S 5   b ). On the other hand, if the phone number of the incoming call matches one of the phone numbers stored in Area  403 , the line is ‘blocked,’ i.e., not connected to Device B (S 5   a ) and Host H sends the massage data stored in Area  404  ( FIG. 57 ) to the caller device (S 6 ). 
       FIG. 59  illustrates the method of updating Area  403  ( FIG. 57 ) of Host H. Assuming that the phone number of the incoming call does not match any of the phone numbers stored in Area  403  (see S 4  of  FIG. 58 ). In that case, Host H allows the connection between the caller device and Communication Device  200 , however, the user of Communication Device  200  may decide to have such number ‘blocked’ after all. If that is the case, the user simply dials ‘999’ while the line is connected. Technically Host H ( FIG. 57 ) periodically checks the signals input from Input Device  210  ( FIG. 1 ) (S 1 ). If the input signal represents ‘999’ from Input Device  210  ( FIG. 1 ) (S 2 ), Host H adds the phone number of the pending call to Area  403  (S 3 ) and sends the message data stored in Area  404  ( FIG. 57 ) to the caller device (S 4 ). The line is disconnected thereafter (S 5 ). 
     As another embodiment of the method illustrated in  FIG. 59 , Host H ( FIG. 57 ) may delegate some of its tasks to Communication Device  200  (this embodiment is not shown in drawings). Namely, Communication Device  200  periodically checks the signals input from Input Device  210  ( FIG. 1 ). If the input signal represents a numeric data ‘999’ from Input Device  210 , Communication Device  200  sends to Host H a block request signal as well as with the phone number of the pending call. Host H, upon receiving the block request signal from Communication Device  200 , adds the phone number of the pending call to Area  403  ( FIG. 57 ) and sends the message data stored in Area  404  ( FIG. 57 ) to the caller device. The line is disconnected thereafter. 
     &lt;&lt;Call Blocking—Summary&gt;&gt; 
     The foregoing invention may be summarized as the following. 
     (1) A communication system comprising a communication device and a blocked number storage means wherein an incoming call is prevented from being connected to said communication device if the phone number of said incoming call is included in said blocked number storage means thereby preventing the user of said communication device from being disturbed from unnecessary calls. 
     (2) A communication system comprising a communication device and a blocked number storage means wherein a pending call is disconnected from said communication device if a predetermined signal is input to said communication device and the phone number of said pending call is included in said blocked number storage means thereby preventing the user of said communication device from being disturbed from unnecessary calls. 
     &lt;&lt;Online Payment Function&gt;&gt; 
       FIGS. 60 through 64  illustrate the method of online payment by utilizing Communication Device  200  ( FIG. 1 ). 
     As illustrated in  FIG. 60 , Host H includes account data storage Area  405 .

In the example described in  FIG. 60 , Account A stores the relevant account data of the user using Device A; Account B stores the relevant account data of the user using Device B; Account C stores the relevant account data of the user using Device C; and Account D stores the relevant account data of the user using device D. Here, Devices A, B, C, and D are Communication Device  200 . 
       FIGS. 61   a  and  61   b  illustrate the operation of the payer device, Communication Device  200 . Assuming that Device A is the payer device and Device B is the payee device. Account A explained in  FIG. 60  stores the account data of the user of Device A, and Account B explained in the same drawing stores the account data of the user of Device B. As illustrated in  FIG. 61   a , LCD  201  ( FIG. 1 ) of Device A displays the balance of Account A by receiving the relevant data from Host H ( FIG. 60 ) (S 1 ). From the signal input from Input Device  210  ( FIG. 1 ), the payer&#39;s account and the payee&#39;s account are selected (in the present example, Account A as the payer&#39;s account and Account B as the payee&#39;s account are selected), and the amount of payment and the device ID (in the present example, Device A as the payer&#39;s device and Device B as the payee&#39;s device) are input via Input Device  210  (S 2 ). If the data input from Input Device  210  is correct (S 3 ), CPU  211  ( FIG. 1 ) of Device A prompts for other payments. If there are other payments to make, the sequence of S 1  through S 3  is repeated until all of the payments are made (S 4 ). The dialing process is initiated and repeated thereafter (S 5 ) until the line is connected to Host H ( FIG. 60 ) (S 6 ). Once the line is connected, Device A sends the payment data to Host H (S 7 ). The line is disconnected when all of the payment data including the data produced in S 2  are sent to Host H (S 8  and S 9 ). 
       FIG. 62  illustrates the payment data described in S 7  of  FIG. 61   b . Payment data  620  is composed of Header  621 , Payer&#39;s Account Information  622 , Payee&#39;s Account Information  623 , amount data  624 , device ID data  625 , and Footer  615 . Payer&#39;s Account Information  622  represents the information regarding the payer&#39;s account data stored in Host H ( FIG. 60 ) which is, in the present example, Account A. Payee&#39;s Account Information  623  represents the information regarding the payee&#39;s account data stored in Host H which is, in the present example, Account B. Amount Data  624  represents the amount of monetary value either in the U.S. dollars or in other currencies which is to be transferred from the payer&#39;s account to the payee&#39;s account. The device ID data represents the data of the payer&#39;s device and the payee&#39;s device, i.e., in the present example, Device A and Device B. 
       FIG. 63  illustrates the basic structure of the payment data described in S 7  of  FIG. 61   b  when multiple payments are made, i.e., when more than one payment is made in S 4  of  FIG. 61   a . Assuming that three payments are made in S 4  of  FIG. 61   a . In that case, Payment Data  630  is composed of Header  631 , Footer  635 , and three data sets, i.e., Data Set  632 , Data Set  633 , Data Set  634 . Each data set represents the data components described in  FIG. 62  excluding Header  621  and Footer  615 . 
       FIG. 64  illustrates the operation of Host H ( FIG. 60 ). After receiving payment data from Device A described in  FIGS. 62 and 63 , Host H retrieves therefrom the payer&#39;s account information (in the present example Account A), the payee&#39;s account information (in the present example Account B), the amount data which represents the monetary value, and the device IDs of both the payer&#39;s device and the payee&#39;s device (in the present example Device A and Device B) (S 1 ). Host H, based on such data, subtracts the monetary value represented by the amount data from the payer&#39;s account (in the present example Account A) (S 2 ), and adds the same amount to the payee&#39;s account (in the present example Account B) (S 3 ). If there are other payments to make, i.e., if Host H received a payment data which has a structure of the one described in  FIG. 63 , the sequence of S 2  and S 3  is repeated as many times as the amount of the data sets are included in such payment data. 
     &lt;&lt;Online Payment—Summary&gt;&gt;

     &lt;&lt;Navigation System&gt;&gt; 
       FIGS. 65 through 74  illustrate the navigation system of Communication Device  200  ( FIG. 1 ). 
     As illustrated in  FIG. 65 , RAM  206  ( FIG. 1 ) includes Area  275 , Area  276 , Area  277 , and Area  295 . Area  275  stores a plurality of map data, two-dimensional (2D) image data, which are designed to be displayed on LCD  201  ( FIG. 1 ). Area  276  stores a plurality of object data, three-dimensional (3D) image data, which are also designed to be displayed on LCD  201 . The object data are primarily displayed by a method so-called ‘texture mapping’ which is explained in details hereinafter. Here, the object data include the three-dimensional data of various types of objects that are displayed on LCD  201 , such as bridges, houses, hotels, motels, inns, gas stations, restaurants, streets, traffic lights, street signs, trees, etc. Area  277  stores a plurality of location data, i.e., data representing the locations of the objects stored in Area  276 . Area  277  also stores a plurality of data representing the street address of each object stored in Area  276 . In addition, Area  277  stores the current position data of Communication Device  200  and the Destination Data which are explained in details hereafter. The map data stored in Area  275  and the location data stored in Area  277  are linked each other. Area  295  stores a plurality of attribution data attributing to the map data stored in Area  275  and location data stored in Area  277 , such as road blocks, traffic accidents, and road constructions, and traffic jams.

     As illustrated in  FIG. 66 , Video Processor  202  ( FIG. 1 ) includes texture mapping processor  290 . Texture mapping processor  290  produces polygons in a three-dimensional space and ‘pastes’ textures to each polygon. The concept of such method is described in the following patents and the references cited thereof: U.S. Pat. No. 5,870,101, U.S. Pat. No. 6,157,384, U.S. Pat. No. 5,774,125, U.S. Pat. No. 5,375,206, and/or U.S. Pat. No. 5,925,127. 
     As illustrated in  FIG. 67 , the voice recognition system is activated when the CPU  211  ( FIG. 1 ) detects a specific signal input from Input Device  210  ( FIG. 1 ) (S 1 ). After the voice recognition system is activated, the input current position mode starts and the current position of Communication Device  200  is input by voice recognition system explained in  FIG. 3 ,  FIG. 4 ,  FIG. 5 ,  FIG. 13 ,  FIG. 14 ,  FIG. 14   a ,  FIG. 15 ,  FIG. 16  and/or  FIG. 17  (S 2 ). The current position can also be input from Input Device  210 . As another embodiment of the present invention, the current position can automatically be detected by the method so-called ‘global positioning system’ or ‘GPS’ as illustrated in  FIGS. 20   a  through  26  and input the current data therefrom. After the process of inputting the current data is completed, the input destination mode starts and the destination is input by the voice recognition system explained above or by the Input Device  210  (S 3 ), and the voice recognition system is deactivated after the process of inputting the Destination Data is completed by utilizing such system (S 4 ). 
       FIG. 68  illustrates the sequence of the input current position mode described in S 2  of  FIG. 67 . When analog audio data is input from Microphone  215  ( FIG. 1 ) (S 1 ), such data is converted into digital audio data by A/D  213  (FIG.  1 ) (S 2 ). The digital audio data is processed by Sound Processor  205  ( FIG. 1 ) to retrieve text and numeric data therefrom (S 3 ). The retrieved data is displayed on LCD  201  ( FIG. 1 ) (S 4 ). The data can be corrected by repeating the sequence of S 1  through S 4  until the correct data is displayed (S 5 ). If the correct data is displayed, such data is registered as current position data (S 6 ). As stated above, the current position data can be input manually by Input Device  210  ( FIG. 1 ) and/or can be automatically input by utilizing the method so-called ‘global positioning system’ or ‘GPS’ as described hereinbefore. 
       FIG. 69  illustrates the sequence of the input destination mode described in S 3  of  FIG. 67 . When analog audio data is input from Microphone  215  ( FIG. 1 ) (S 1 ), such data is converted into digital audio data by A/D  213  ( FIG. 1 ) (S 2 ). The digital audio data is processed by Sound Processor  205  ( FIG. 1 ) to retrieve text and numeric data therefrom (S 3 ). The retrieved data is displayed on LCD  201  ( FIG. 1 ) (S 4 ). The data can be corrected by repeating the sequence of S 1  through S 4  until the correct data is displayed on LCD  201  (S 5 ). If the correct data is displayed, such data is registered as Destination Data (S 6 ). 
       FIG. 70  illustrates the sequence of displaying the shortest route from the current position to the destination. CPU  211  ( FIG. 1 ) retrieves both the current position data and the Destination Data which are input by the method described in  FIGS. 67 through 69  from Area  277  ( FIG. 65 ) of RAM  206  ( FIG. 1 ). By utilizing the location data of streets, bridges, traffic lights and other relevant data, CPU  211  calculates the shortest route to the destination (S 1 ). CPU  211  then retrieves the relevant two-dimensional map data which should be displayed on LCD  201  from Area  275  ( FIG. 65 ) of RAM  206  (S 2 ). 
     As another embodiment of the present invention, by way of utilizing the location data stored in Area  277 , CPU  211  may produce a three-dimensional map by composing the three dimensional objects (by method so-called ‘texture mapping’ as described above) which are stored in Area  276  (FIG.  65 ) of RAM  206 . The two-dimensional map and/or the three dimensional map is displayed on LCD  201  ( FIG. 1 ) (S 3 ). 
     As another embodiment of the present invention, the attribution data stored in Area  295  ( FIG. 65 ) of RAM  206  may be utilized. Namely if any road block, traffic accident, road construction, and/or traffic jam is included in the shortest route calculated by the method mentioned above, CPU  211  ( FIG. 1 ) calculates the second shortest route to the destination. If the second shortest route still includes road block, traffic accident, road construction, and/or traffic jam, CPU  211  calculates the third shortest route to the destination. CPU  211  calculates repeatedly until the calculated route does not include any road block, traffic accident, road construction, and/or traffic jam. The shortest route to the destination is highlighted by a significant color (such as red) to enable the user of Communication Device  200  to easily recognize such route on LCD  201  ( FIG. 1 ). 
     As another embodiment of the present invention, an image which is similar to the one which is observed by the user in the real world may be displayed on LCD  201  ( FIG. 1 ) by utilizing the three-dimensional object data. In order to produce such image, CPU  211  ( FIG. 1 ) identifies the present location and retrieves the corresponding location data from Area  277  ( FIG. 65 ) of RAM  206 . Then CPU  211  retrieves a plurality of object data which correspond to such location data from Area  276  ( FIG. 65 ) of RAM  206  and displays a plurality of objects on LCD  201  based on such object data in a manner the user of Communication Device  200  may observe from the current location. 
       FIG. 71  illustrates the sequence of updating the shortest route to the destination while Communication Device  200  is moving. By way of periodically and automatically inputting the current position by the method so-called ‘global positioning system’ or ‘GPS’ as described hereinbefore, the current position is continuously updated (S 1 ). By utilizing the location data of streets and traffic lights and other relevant data, CPU  211  ( FIG. 1 ) recalculates the shortest route to the destination (S 2 ). CPU  211  then retrieves the relevant two-dimensional map data which should be displayed on LCD  201  from Area  275  ( FIG. 65 ) of RAM  206  (S 3 ). Instead, by way of utilizing the location data stored in Area  277  ( FIG. 65 ), CPU  211  may produce a three-dimensional map by composing the three dimensional objects by method so-called ‘texture mapping’ which are stored in Area  276  ( FIG. 65 ) of RAM  206 . The two-dimensional map and/or the three-dimensional map is displayed on LCD  201  ( FIG. 1 ) (S 4 ). The shortest route to the destination is re-highlighted by a significant color (such as red) to enable the user of Communication Device  200  to easily recognize the updated route on LCD  201 . 
       FIG. 72  illustrates the method of finding the shortest location of the desired facility, such as restaurant, hotel, gas station, etc. The voice recognition system is activated in the manner described in  FIG. 67  (S 1 ). By way of utilizing the voice recognition system, a certain type of facility is selected from the options displayed on LCD  201  ( FIG. 1 ). The prepared options can be a) restaurant, b) lodge, and c) gas station (S 2 ). Once one of the options is selected, CPU  211  ( FIG. 1 ) calculates and inputs the current position by the method described in  FIG. 68  and/or  FIG. 71  (S 3 ). From the data selected in S 2 , CPU  211  scans Area  277  ( FIG. 65 ) of RAM  206  and searches the location of the facilities of the selected category (such as restaurant) which is the closest to the current position (S 4 ). CPU  211  then retrieves the relevant two-dimensional map data which should be displayed on LCD  201  from Area  275  of RAM  206  ( FIG. 65 ) (S 5 ). Instead, by way of utilizing the location data stored in  277  ( FIG. 65 ), CPU  211  may produce a three-dimensional map by composing the three dimensional objects by method so-called ‘texture mapping’ which are stored in Area  276  ( FIG. 65 ) of RAM  206 . The two-dimensional map and/or the three dimensional map is displayed on LCD  201  ( FIG. 1 ) (S 6 ). The shortest route to the destination is re-highlighted by a significant color (such as red) to enable the user of Communication Device  200  to easily recognize the updated route on LCD  201 . The voice recognition system is deactivated thereafter (S 7 ). 
       FIG. 73  illustrates the method of displaying the time and distance to the destination. As illustrated in  FIG. 73 , CPU  211  ( FIG. 1 ) calculates the current position wherein the source data can be input from the method described in  FIG. 68  and/or  FIG. 71  (S 1 ). The distance is calculated from the method described in  FIG. 70  (S 2 ). The speed is calculated from the distance which Communication Device  200  has proceeded within specific period of time (S 3 ). The distance to the destination and the time left are displayed on LCD  201  ( FIG. 1 ) (S 4  and S 5 ). 
       FIG. 74  illustrates the method of warning and giving instructions when the user of Communication Device  200  deviates from the correct route. By way of periodically and automatically inputting the current position by the method so-called ‘global positioning system’ or ‘GPS’ as described hereinbefore, the current position is continuously updated (S 1 ). If the current position deviates from the correct route (S 2 ), a warning is given from Speaker  216  ( FIG. 1 ) and/or on LCD  201  ( FIG. 1 ) (S 3 ). The method described in  FIG. 74  is repeated for a certain period of time. If the deviation still exists after such period of time has passed, CPU  211  ( FIG. 1 ) initiates the sequence described in  FIG. 70  and calculates the shortest route to the destination and display it on LCD  201 . The details of such sequence is as same as the one explained in  FIG. 70 . 
       FIG. 74   a  illustrates the overall operation of Communication Device  200  regarding the navigation system and the communication system. When Communication Device  200  receives data from Antenna  218  ( FIG. 1 ) (S 1 ), CPU  211  ( FIG. 1 ) determines whether the data is navigation data, i.e., data necessary to operate the navigation system (S 2 ). If the data received is a navigation data, the navigation system described in  FIGS. 67 through 74  is performed (S 3 ). On the other hand, if the data received is a communication data (S 4 ), the communication system, i.e., the system necessary for wireless communication which is mainly described in  FIG. 1  is performed (S 5 ).
