  Next, operations of the communication system and the communication device apparatus of the present invention having the above configuration will be described. In the communication system and the communication device of the present embodiment, at the time of outgoing call or incoming call, whether or not the mobile phone of the other party of the call destination is located in the vicinity, or whether the mobile phone sent to the own device is located in the vicinity The operation to judge is performed. This operation is largely divided into an operation when a call is made from one person (one communication device), an action when an incoming call is received, and an operation when a call is sent from a plurality of persons (multiple communication devices). Separated. Hereinafter, operations in each of these cases will be described in order.

[Operation when making a call with one person]
FIG. 3 is a flowchart showing a process performed when a mobile phone is used to make a call to one partner, and FIG. 4 shows a transition of display contents on the display unit of the mobile phone at the time of making a call to one partner. FIG. In the following description, a case where a call is made to the mobile phone 20 using the mobile phone 10 as shown in FIG. 1 will be described as an example. Further, it is assumed that the mobile phone 20 is located around the mobile phone 10 (about several meters to several tens of meters).

  When the user operates the numeric keypad provided on the operation unit 16 of the mobile phone 10 to input the phone number of the mobile phone 20 or specifies the user (phone number) of the mobile phone 20 using the address book function, As shown in FIG. 4A, the display unit 17 of the mobile phone 10 displays the user name “UserA” of the mobile phone 20 and a call button B1. Next, when the user presses a call key provided in the operation unit 16 or operates a soft key or the like to press the call button B1, a call operation from the mobile phone 10 to the base station B is usually performed. However, in this embodiment, the transmission operation is temporarily restricted.

  In a state where the outgoing call operation is temporarily restricted, the control unit 13 searches the storage unit 15 using the destination telephone number as a key, and acquires ID information (communication device specific information) corresponding to the telephone number. (Step S11). The ID information acquired here is referred to as “ID information A” for convenience. When acquiring the ID information A, the control unit 13 controls the RFID unit 19 to transmit an interrogation radio wave to the surroundings via the antenna 18, so that the cellular phone (peripheral communication device) located around the cellular phone 10 is ID information (peripheral device specific information) is received (step S12).

  Since other mobile phones may be located in the vicinity of the mobile phone 10 in addition to the plurality of mobile phones 20, a plurality of ID information may be received. For this reason, the ID information received here is referred to as “ID information B group” for convenience. During the process of step S12, as shown in FIG. 4B, the display unit 17 displays “UserA being received” indicating that the ID information from the mobile phone 20 is received. The

  When the process of step S12 ends, the control unit 13 determines whether or not the ID information A acquired in step S11 is included in the ID information B group received in step S12 (step S13). When the determination result is “NO” (when the ID information A is not included in the ID information B group (including the case where the ID information of the mobile phone 20 is not received)), the ID information A is sent to the user. The fact that it was not found is notified (step S14). For example, as shown in FIG. 4D, the display unit 17 displays “User A was not found” as the ID information reception result.

  When such display is performed for a certain time (for example, several seconds), the control unit 13 automatically cancels the transmission operation temporarily restricted before Step S11 and starts the transmission operation (Step S15). When the transmission operation is performed, a display “Calling UserA ...” is displayed on the display unit 17 of the mobile phone 10 as shown in FIG. 4F, for example. After the transmission operation is performed, the same processing as the conventional mobile phone (processing such as call processing and disconnection processing) is performed. Note that the result of whether or not the callee ID information has been received may be added to the call history after the call process and the call process are completed.

  On the other hand, when the determination result of step S13 is “YES”, that is, when the mobile phone 20 is located in the vicinity of the mobile phone 10 (ID information receivable region R) and the ID information of the mobile phone 20 is received. The control unit 13 notifies the user that the ID information A has been found (step S16). For example, as shown in FIG. 4C, “User A was found” is displayed on the display unit 17 as a reception result of the ID information to notify that the mobile phone 20 as the communication partner is located in the vicinity. In addition to such a display, a display “Do you want to make a call” confirming whether or not to make a call to the other party, and a “Yes” button B2 and a “No” button B3 are displayed.

  When such a display is performed, the control unit 13 determines whether any of the “Yes” button B2 and the “No” button B3 is pressed by the user, that is, whether to make a call to the mobile phone 20 having the ID information A. Judgment is made (step S17). When the “Yes” button B2 is pressed by the user, the determination result in Step S17 is “YES”, and the control unit 13 automatically cancels the transmission operation temporarily restricted before Step S11, and performs the transmission operation. Is started (step S15).

  When the transmission operation is performed, a display “Calling UserA ...” is displayed on the display unit 17 of the mobile phone 10 as shown in FIG. 4F, for example. After the transmission operation is performed, the same processing as the conventional mobile phone (processing such as call processing and disconnection processing) is performed. Note that the result of whether or not the callee ID information has been received may be added to the call history after the call process and the call process are completed. On the other hand, when the “NO” button B3 is pressed by the user, the temporarily restricted outgoing operation is stopped, and a normal standby screen is displayed on the display unit 17 of the mobile phone 10 as shown in FIG. Is displayed.

  As described above, when the determination result in step S13 is “YES” and the mobile phone 10 and the mobile phone 20 are located in the vicinity of each other, temporary restriction of the outgoing call operation performed before step S11 is performed. , The transmission from the mobile phone 10 to the mobile phone 20 located in the vicinity is restricted, the determination result in step S13 is “NO”, and the mobile phone 10 and the mobile phone 20 are located in the vicinity of each other. If not, the temporary restriction on the call operation performed before step S11 is released, and the call from the mobile phone 10 to the mobile phone 20 located in the vicinity is permitted.

  When the mobile phone 10 and the mobile phone 20 are located in the vicinity of each other and transmission from the mobile phone 10 to the mobile phone 20 located in the vicinity is restricted, the display unit 17 of the mobile phone 10 displays “ When the message “Do you want to make a call?” Is displayed, the user of the mobile phone 10 is notified that the call restriction (communication restriction) is being performed. In addition, when “Do you want to make a call?” Is displayed on the display unit 17 of the mobile phone 10 and the outgoing call is restricted, either the “Yes” button B2 or the “No” button B3 is pressed. Therefore, it is possible to select whether or not to perform (continue) transmission restriction (communication restriction).

[Operation when there is an incoming call]
FIG. 5 is a flowchart showing processing performed when an incoming call is made to the mobile phone, and FIG. 6 is a diagram showing transition of display contents on the display unit of the mobile phone when the incoming call is received. In the following description, the case where there is an incoming call from the mobile phone 20 to the mobile phone 10 as shown in FIG. 1 will be described as an example. Further, it is assumed that the mobile phone 20 is located around the mobile phone 10 (about several meters to several tens of meters).

  Before an incoming call from the mobile phone 20 to the mobile phone 10, a normal standby screen is displayed on the display unit 17 of the mobile phone 10 as shown in FIG. When there is an incoming call from the mobile phone 20 to the mobile phone 10, the control unit 13 of the mobile phone 10 acquires the telephone number of the caller (mobile phone 20) (step S21). Next, the storage unit 15 is searched using the telephone number acquired in step S21 as a key, and ID information corresponding to the telephone number is acquired (step S22). The ID information acquired here is referred to as “ID information A” for convenience.

  When acquiring the ID information A, the control unit 13 controls the RFID unit 19 to transmit an interrogation radio wave to the periphery via the antenna 18 and receive the ID information of the mobile phone located around the mobile phone 10 ( Step S23). During this process, the display unit 17 of the mobile phone 10 displays “From UserA” indicating that there is an incoming call from the user (UserA) of the mobile phone 20 as shown in FIG. A message “Incoming call” is displayed, and a message “ID information searching” indicating that ID information is being received from a mobile phone located in the vicinity is displayed. Since other mobile phones may be located in the vicinity of the mobile phone 10 in addition to the plurality of mobile phones 20, a plurality of ID information may be received. For this reason, the ID information received here is referred to as “ID information B group” for convenience.

  When the process of step S23 ends, the control unit 13 determines whether or not the ID information A acquired in step S22 is included in the ID information B group received in step S23 (step S24). When the determination result is “NO” (when the ID information A is not included in the ID information B group (including the case where the ID information of the mobile phone 20 is not received)), the ID information A is sent to the user. The fact that it was not found is notified (step S25). For example, as shown in FIG. 6D, the display unit 17 displays “Incoming from User A” and displays “User A was not found” as the ID information reception result. In addition to these displays, a “response” button B4 and a “no response” button B5 for instructing whether or not to respond to an incoming call from the other party are displayed.

  When such a display is performed, the control unit 13 determines whether the “response” button B4 or the “do not respond” button B5 is pressed by the user, that is, whether to respond to the incoming call (step S26). When the “response” button B4 is pressed by the user, the determination result in step S26 is “YES”, and the control unit 13 displays on the display unit 17 a “busy with UserA” as shown in FIG. And a control to start a call operation. On the other hand, when the “do not respond” button B5 is pressed by the user, the control unit 13 does not respond to the incoming call or cuts off the incoming call, and displays a normal standby screen on the display unit as shown in FIG. . Note that the result of whether or not the callee ID information has been received may be added to the incoming call history after the incoming call process or the call process ends.

  On the other hand, if the determination result in step S24 is "YES", the user is notified that ID information A has been found (step S27). For example, as shown in FIG. 6C, a message “User A is found” is displayed on the display unit 17 as well as “User A was found” as a reception result of the ID information. Is in the vicinity. In addition to these displays, a “response” button B4 and a “no response” button B5 for instructing whether or not to respond to an incoming call from the other party are displayed.

  When such a display is performed, the control unit 13 determines whether the “response” button B4 or the “do not respond” button B5 is pressed by the user, that is, whether to respond to the incoming call (step S26). When the “response” button B4 is pressed by the user, the determination result in step S26 is “YES”, and the control unit 13 displays on the display unit 17 a “busy with UserA” as shown in FIG. And a control to start a call operation. On the other hand, when the “do not respond” button B5 is pressed by the user, the control unit 13 does not respond to the incoming call or cuts off the incoming call, and displays a normal standby screen on the display unit as shown in FIG. . Note that the result of whether or not the callee ID information has been received may be added to the incoming call history after the incoming call process or the call process ends.

[Operation when calling multiple people]
FIG. 7 is a flowchart showing a process performed when a mobile phone is used to make a call to a plurality of persons, and FIG. 8 shows a transition of display contents on the display unit of the mobile phone when a call is made to a plurality of persons. FIG. In the following description, a case where a call is made to a plurality of mobile phones (not shown) using the mobile phone 10 shown in FIG. 1 will be described as an example.

  When the user operates a numeric keypad provided on the operation unit 16 of the mobile phone 10 to input a plurality of telephone numbers of the mobile phone of the other party or specifies a plurality of other parties using the address book function, FIG. As shown in a), the display unit 17 of the mobile phone 10 displays a plurality of user names (here, “UserA” to “UserE”) specified by the user and a call button B6. Next, when the user presses a call key provided on the operation unit 16 or operates a soft key or the like to press the call button B6, the call operation is temporarily restricted.

  In a state where the outgoing operation is temporarily restricted, the control unit 13 searches the storage unit 15 using the destination telephone number as a key, and acquires ID information corresponding to the plurality of outgoing telephone numbers (step S31). ). The plurality of ID information acquired here is referred to as “ID information A group” for convenience. When the ID information A group is acquired, the control unit 13 controls the RFID unit 19 and transmits the interrogation radio wave to the surroundings via the antenna 18 in the same manner as [operation when transmitting one person as an opponent] ID information of mobile phones located around the mobile phone 10 is received (step S32). The ID information received here is referred to as “ID information B group” for convenience.

  During the process of step S32, as shown in FIG. 8B, “ID information from a mobile phone possessed by each of a plurality of partners specified by the user is received”. The display unit 17 displays “UserA being received” to “UserE being received”. When the process of step S32 ends, the control unit 13 determines whether or not the ID information A group acquired in step S31 is all included in the ID information B group received in step S32 (step S33). When this determination result is “NO” (when there is an ID information A group that is not included in the ID information B group), a list of search results of the ID information A group is notified to the user (step). S34).

  For example, when only the ID information from the mobile phones possessed by “UserB” and “UserD” among “UserA” to “UserE” cannot be received, as shown in FIG. In the list of search results of ID information A group, “UserB was not found” and “UserD was not found” are displayed. On the other hand, “UserA was found”, “UserC was found”, “UserE was found” is displayed for “UserA”, “UserC”, and “UserE” for which ID information was received. Each done. When displaying a list of search results, as shown in FIG. 8 (d), items that are not included in the ID information B group of the ID information A group ("UserB", "UserD") and those that are included ("UserA", "UserC", and "UserE") are displayed together, and the display of the ID information A group is prior to the one that is not included in the ID information B group (display). It is desirable to display it above (upper part 17).

  When the above display is performed, the control unit 13 can preferentially transmit to the ID information A group (“UserB” and “UserD” in the example shown in FIG. 8) not included in the ID information B group. (Step S35). For example, as shown in FIG. 8 (f), at least one of the portions where “not found” is displayed is highlighted or highlighted, and “is not found” is displayed. Control is performed so that only the displayed part can be selected. As a result, the transmission to the user displayed in the portion where the display of “cannot be found” is permitted. In addition, here, we will explain the case where only the part that is displayed as "~ was not found" can be selected as an example, but the part that is displayed as "~ was found" It is also possible to select this.

  When the user operates the operation unit 16 and selects any one of the portions where “-” was not found ”is displayed, a transmission operation for the selected user is performed. When the transmission operation is performed, a display “calling” is displayed on the display unit 17 of the mobile phone 10 as shown in FIG. When the selected partner answers the phone, the mobile phone 10 and the mobile phone possessed by the partner are busy (step S36).

  While the call is being made, it is determined whether or not the call with the other party currently on the call has ended (step S37). If this determination is “NO”, the call is continued (step S36). On the other hand, when the determination result of step S37 is “YES”, the control unit 13 performs a process of updating the ID information A group (step S38). Specifically, a process of excluding the ID information of the mobile phone held by the user who made the call in step S36 from the ID information A group is performed. Next, the control unit 13 of the mobile phone 10 determines whether or not ID information is included in the ID information A group (step S39). When the determination result is “NO”, the series of processing ends. On the other hand, if the decision result in the step S39 is “YES”, the process returns to the step S32, and the process of receiving the ID information of the mobile phone located around the mobile phone 10 is performed again.

  On the other hand, if the determination result in step S33 is “YES”, that is, if the ID information A group acquired in step S31 is all included in the ID information B group received in step S32, the user is searched for the ID information A group. A list of results is notified (step S40). At this time, as shown in FIG. 8C, for example, “UserA was found” to “UserE was found” are displayed on the display unit 17 as a list of search results of the ID information A group. A message “Do you want to make a call?” For confirming whether or not to make a call to the other party, and a “Yes” button B7 and a “No” button B8 are displayed.

  In a state where such a display is made, the control unit 13 determines whether the “Yes” button B7 or “No” has been pressed by the user, that is, whether to transmit to any of the ID information A group. (Step S41). When the user presses the “Yes” button B7, the determination result in Step S41 is “YES”, and the control unit 13 displays “Yes” on the display unit 17 of the mobile phone 10 as shown in FIG. "B7" and "No" button B8 are erased and "Transmission start" button B9 is displayed, and at least one of the parts where "-" is found "is highlighted or highlighted. Control the display. As a result, any one of “UserA” to “UserE” can be selected to place a call.

  In a state where the display shown in FIG. 8E is made, the user operates the operation unit 16 to select at least one of the parts where “~ is found” is displayed. The outgoing call operation is performed for the selected user. When the transmission operation is performed, a display “calling” is displayed on the display unit 17 of the mobile phone 10 as shown in FIG. When the selected partner answers the phone, the mobile phone 10 and the mobile phone possessed by the partner are busy (step S36).

  If the “NO” button B8 is pressed by the user while the display shown in FIG. 8C is displayed on the display unit 17 of the mobile phone 10, the determination result in step S41 is “NO”. As a result, the temporarily restricted outgoing call operation is stopped, and a normal standby screen is displayed on the display unit 17 of the mobile phone 10 as shown in FIG. 8G, and a series of processing ends.

  As described above, in both cases of making a call to one person and making a call to a plurality of persons, the call operation is temporarily stopped when the user operates the call key, and the other party's mobile phone is located in the vicinity. It is possible to select whether or not to make a call to the mobile phone when it is determined that the mobile phone is located in the vicinity. For this reason, for example, when it is determined that the other party's mobile phone is located nearby, the transmission operation can be stopped by the user's selection, thereby wasteful consumption of communication system resources and communication cost. Can be saved. In addition, when a plurality of persons are transmitted as a partner, since a call can be preferentially made to the mobile phone of the partner that has not been searched, it is possible to efficiently communicate.

  When there is an incoming call, it is determined whether or not the caller (mobile phone 20) is located in the vicinity, and it is possible to select whether or not the user responds to the incoming call based on the determination result. As a result, when it is determined that the other party's mobile phone is located nearby, the user is not responding to the incoming call, so that the incoming call is restricted, and wasteful consumption of communication system resources and waste of communication cost are suppressed. be able to.

  As described above, the operation of the communication system and the communication device according to the embodiment of the present invention has been described. Next, the operation of searching for the peripheral mobile phone by receiving the ID information of the mobile phone located in the vicinity (hereinafter referred to as ID) Information reception operation) will be described in detail. The ID information receiving operation is an operation performed in step S12 in FIG. 3, step S23 in FIG. 5, and step S32 in FIG. The ID information receiving operation is roughly classified into an operation for searching with a fixed search range (fixed operation) and an operation for searching with a variable search range (automatic operation). In the fixed operation, the radio wave intensity of the interrogation radio wave is fixed, and in the automatic operation, the radio wave intensity of the interrogation radio wave is varied. Hereinafter, each of these operations will be described.

  FIG. 9 is a flowchart showing details of the ID information receiving operation. As described above, the ID information receiving operation is an operation performed in step S12 in FIG. 3, step S23 in FIG. 5, and step S32 in FIG. The reception operation, that is, the ID information reception operation performed in step S12 in FIG. 3 and step S32 in FIG. 7 will be described as an example.

  The flowchart shown in FIG. 9 is roughly divided into a case where the user selects a fixed operation and a case where an automatic operation is selected. When it is preset that the user performs the fixed operation, the control unit 13 selects the fixed operation (step S51). Then, various initial settings for the fixed operation are performed (step S52). The initial setting performed here is, for example, a search range setting (interrogation radio wave intensity setting), a reception time for receiving ID information, and the like. These are set in advance by the user, and in step S52, processing for setting the user's setting contents as initial values is performed.

  When the above initial setting is completed, the control unit 13 controls the RFID unit 19 to transmit the interrogation radio wave from the antenna 18 and starts counting the reception time (step S53). Next, the control unit 13 determines whether or not the count value of the reception time exceeds the reception time set in step S52 (step S54). When the determination result is “NO”, when the received ID information includes the destination partner, the information of the destination partner is updated (step S55). For example, the information of the other party of the call destination is updated to information including that the ID information has been received. On the other hand, when the determination result of step S54 is “YES”, the control unit 13 ends the ID information receiving process.

  On the other hand, when it is set in advance that the automatic operation is performed by the user, the control unit 13 selects the automatic operation (step S61). Then, various initial settings for automatic operation are performed (step S62). The initial setting performed here is, for example, setting of the search range (setting of the maximum radio wave intensity Smax of the interrogation radio wave, step value d for changing the transmission intensity), reception time for receiving the ID information, and the like. These are set in advance by the user, and in step S62, processing for setting the user's setting content as an initial value is performed.

  When the above initial setting is completed, the control unit 13 controls the RFID unit 19 to transmit the inquiry radio wave from the antenna 18 and starts counting the reception time (step S63). It is assumed that the initial value of the transmission intensity Ssend of the interrogation radio wave is set to the maximum intensity Smax. Next, the control unit 13 determines whether or not the count value of the reception time exceeds the reception time set in step S62 (step S64). If the determination result is “NO”, it is determined whether or not the radio wave intensity Ssend of the transmitted inquiry radio wave is greater than “0” (step S65).

  If the determination result in step S65 is “YES”, ID information is received from the surrounding mobile phones (step S66). Next, the control unit 13 determines whether or not the ID information received in step S66 includes the ID information of the destination mobile phone (step S67). If the determination result is “YES”, the information of the other party of the ID information is updated (step S68). For example, the information of the other party of the call destination is updated to information including that the ID information has been received. Next, the control unit 13 performs control to update the radio wave intensity of the transmitted inquiry radio wave (step S69). Specifically, the transmission intensity Ssend of the interrogation radio wave is updated to the intensity obtained by subtracting the step value d from the transmission intensity Ssend of the current interrogation radio wave. When the above process ends, the process returns to step S64.

  On the other hand, when the determination result at step S65 is “NO” (when the radio wave intensity Send of the interrogation radio wave to be transmitted is “0” or less), or when the determination result at step S67 is “NO” (received at step S66). If the ID information does not include the ID information of the destination mobile phone, the radio wave intensity of the interrogation radio wave to be transmitted is initialized (step S70). Specifically, the radio wave intensity Ssend of the interrogation radio wave to be transmitted is set to the maximum intensity Smax. When this process ends, the process proceeds to step S66. On the other hand, if the determination result in step S64 is “YES”, that is, if the count value of the reception time exceeds the reception time set in step S62, the ID information reception operation process ends.

  Next, a specific example of the automatic operation in the flowchart shown in FIG. 9 will be described. FIG. 10 is a diagram for explaining a first example of the automatic operation. Now, it is assumed that the mobile phone 10 in FIG. 1 is arranged at the position of an asterisk indicated by the symbol A in FIG. Further, it is assumed that the other five mobile phones to which the call is made are arranged around the mobile phone 10 and at the positions of the asterisks marked with symbols B to F in FIG. Here, the radio wave intensity of the interrogation radio wave of the mobile phone 10 changes in the range of S1, S2, S3 (S1 <S2 <S3) as shown in FIG. The search range is assumed to be a range indicated by circles denoted by reference signs s1, s2, and s3 in FIG.

  When the automatic operation of the flowchart shown in FIG. 9 is started, the radio wave intensity of the interrogation radio wave of the mobile phone 10 is set to the maximum intensity Smax (S3) in step S62, and in step S66, the symbol s3 in FIG. Is searched (time t0 to t1 in FIG. 10B). As a result of this search, the mobile phone 10 at the position of the star marked with the symbol A in FIG. 10A receives ID information from the mobile phone located within the search range attached with the symbol s3. In other words, ID information is received from the mobile phone at the position of the star marked with the symbols B, D, E, and F, and the ID information from the mobile phone at the position of the star marked with the reference C is received. Can not.

  When the ID information is received, the processing at steps S67 and S68 is sequentially performed, and the radio wave intensity of the interrogation radio wave of the mobile phone 10 is set to S2 at step S69. After this setting, steps S64 and S65 are passed through in order, and in step S66, the search range to which reference numeral s2 in FIG. 10A is attached is searched (time t1 to t2 in FIG. 10B). As a result of this search, the mobile phone 10 at the position of the star marked with the symbol A in FIG. 10A is the mobile phone located within the search range marked with the symbol s2, that is, the symbols B, E, F. ID information is received from the mobile phone at the position of the star marked with. From the above search results, the control unit 13 of the mobile phone 10 indicates that the mobile phone with the symbol D is located within the search range with the symbol s3 and outside the search range with the symbol s2. Judgment can be made.

  When the above processing is completed, the radio wave intensity of the interrogation radio wave of the mobile phone 10 is updated again in step S69 and set to S1. Then, in step S66, the search range indicated by the symbol s1 in FIG. 10A is searched (time t2 to t3 in FIG. 10B). As a result of this search, the mobile phone 10 at the position of the star marked with the symbol A in FIG. 10A is given the mobile phone located within the search range marked with the symbol s1, ie, the symbol E. ID information is received only from the mobile phone at the position of the star. From the above search results, the control unit 13 of the mobile phone 10 indicates that the mobile phone with the symbols D and F is located within the search range with the symbol s2 and outside the search range with the symbol s1, It can be determined that the mobile phone with the symbol E is located within the search range with the symbol s1.

  Next, in step S69, the radio wave intensity of the interrogation radio wave of the mobile phone 10 is updated, but the interrogation radio wave intensity becomes “0” or less. As a result, the determination result in step S65 becomes “NO”, the radio wave intensity of the interrogation radio wave transmitted in step S70 is initialized, and then the search range indicated by the symbol s3 is searched in step S66 (FIG. 10 (b), times t3 to t4). The above processing is performed until the specified reception time is exceeded (until the determination result in step S64 becomes “YES”). As a result of the above processing, as shown in FIG. 10C, a table indicating the distance range of the destination mobile phone can be obtained. As for the order of the tables, the table in which the ID information could not be received is arranged at the top, and then arranged in the order of the next largest distance.

  FIG. 11 is a diagram for explaining a second example of the automatic operation. In FIG. 11, as in FIG. 10, it is assumed that the mobile phone 10 in FIG. 1 is arranged at the position of an asterisk marked with the symbol A in FIG. Further, it is assumed that the other five mobile phones of the call destination are arranged around the mobile phone 10 and at the positions of the asterisks marked with symbols B to F in FIG. Further, the radio wave intensity of the interrogation radio wave of the mobile phone 10 changes in the range of S1, S2, S3 (S1 <S2 <S3) as shown in FIG. 11B, and the radio wave intensity at each of the radio wave intensity S1, S2, S3. The search range is assumed to be a range indicated by circles denoted by reference signs s1, s2, and s3 in FIG.

  When the automatic operation of the flowchart shown in FIG. 9 is started, the radio wave intensity of the interrogation radio wave of the mobile phone 10 is set to the maximum intensity Smax (S3) in step S62, and in step S66, the symbol s3 in FIG. Is searched (time t0 to t1 in FIG. 11B). As a result of this search, the mobile phone 10 at the position of the star marked with the symbol A in FIG. 11A receives ID information from the mobile phone located within the search range attached with the symbol s3. In other words, ID information is received from the mobile phone at the star positions labeled D, E, and F, and ID information is received from the mobile phone at the star positions labeled B and C. Can not.

  When the ID information is received, the processing at steps S67 and S68 is sequentially performed, and the radio wave intensity of the interrogation radio wave of the mobile phone 10 is set to S2 at step S69. After this setting, steps S64 and S65 are passed through in order, and in step S66, the search range indicated by the symbol s2 in FIG. 11A is searched (time t1 to t2 in FIG. 11B). As shown in FIG. 11A, the mobile phone 10 cannot receive the ID information because no other mobile phone is located within the search range labeled s2. As a result of the above processing, the control unit 13 of the mobile phone 10 searches the control unit 13 for the mobile phone to which the reference signs D, E, and F are attached within the search range to which the reference sign s3 is attached. It can be determined that the mobile phone that is located outside the range and that is assigned with the symbols B and C is located outside the search range that is assigned the symbol s3.

  Since the ID information is not received in step S66, the determination result in step S67 is “NO”. As a result, the radio wave intensity of the interrogation radio wave transmitted in step S70 is initialized, and then the search range to which the code s3 is attached is searched in step S66 (time t2 to t3 in FIG. 11B). Thereafter, the ID reception operation in which the intensity signal of the interrogation radio wave to be transmitted is set to S3 or S2 is performed until the specified reception time is exceeded (until the determination result in step S64 becomes “YES”). By the above processing, as shown in FIG. 11 (c), a table indicating how far the destination mobile phone is located can be obtained. As for the order of the tables, the table in which the ID information could not be received is arranged at the top, and then arranged in the order of the next largest distance.

  FIG. 12 is a diagram for explaining a third example of the automatic operation. Also in FIG. 12, similarly to FIGS. 10 and 11, it is assumed that the mobile phone 10 in FIG. 1 is arranged at the position of the star marked with the symbol A in FIG. Further, it is assumed that the other five mobile phones to which the call is to be made are arranged around the mobile phone 10 and at the positions of the asterisks marked with symbols B to F in FIG. Further, the radio wave intensity of the interrogation radio wave of the mobile phone 10 changes in the range of S1, S2, S3 (S1 <S2 <S3) as shown in FIG. 12B, and the radio wave intensity at each radio wave intensity S1, S2, S3. The search range is assumed to be a range indicated by circles denoted by reference signs s1, s2, and s3 in FIG.

  When the automatic operation of the flowchart shown in FIG. 9 is started, the radio wave intensity of the interrogation radio wave of the mobile phone 10 is set to the maximum intensity Smax (S3) in step S62, and in step S66, the symbol s3 in FIG. Is searched (time t0 to t1 in FIG. 12B). As a result of this search, the mobile phone 10 at the position of the star marked with the symbol A in FIG. 12A receives ID information from the mobile phone located within the search range attached with the symbol s3.

  However, in the example shown in FIG. 12 (a), none of the other mobile phones is located within the search range indicated by the symbol s3, and therefore ID information cannot be received. Therefore, the determination result in step S67 is “NO”, and thereafter, the processes in steps S70, S66, and S67 are performed until the designated reception time is exceeded (until the determination result in step S64 becomes “YES”). By the above processing, as shown in FIG. 12C, it is possible to obtain a table indicating that all the destination mobile phones are out of service area.

  In the automatic operation described above, it is possible to obtain a rough distance between the mobile phone 10 and another mobile phone as well as whether or not another mobile phone has been searched. For this reason. When the ID reception results shown in FIGS. 8C and 8D are displayed on the display unit 17 of the mobile phone 10, it is desirable to display the distance for each mobile phone. FIG. 13 is a diagram illustrating a display example indicating the distance for each mobile phone.

  First, as shown in FIG. 13A, the user of the mobile phone 10 selects “UserA” to “UserE” as the other party, and the call button on the operation unit 16 or the “call” button shown in FIG. When B6 is pressed, an automatic operation is performed in step S32 in FIG. It is assumed that a search result as shown in FIG. 13B is obtained as a result of this automatic reception. As a search result at this time, as shown in FIG. 13C, the expression “found in the distance”, “found in the vicinity”, or “found in the vicinity” is used between the mobile phone of the transmission destination. It is desirable to display the distance. In this way, not only whether or not the mobile phone that is the communication partner is located in the vicinity, but also the location information of the mobile phone is notified.

  The communication system and the communication device according to the embodiment of the present invention have been described above, but the present invention is not limited to the above embodiment and can be freely changed within the scope of the present invention. For example, in the above-described embodiment, it is determined whether or not a mobile phone is located in the vicinity by receiving ID information. However, information obtained from GPS (Global Positioning System) is used for each mobile phone. The position may be determined, the distance between mobile phones with which communication is performed may be detected, or position information may be notified.

  Further, in the above-described embodiment, the case where the mobile phone that has received the ID information regulates the call operation by itself when the call destination mobile phone is located in the vicinity has been described as an example. However, a function for determining whether or not a plurality of mobile phones performing communication are located in the vicinity of each other, a function for restricting communication between them when it is determined that they are located in the vicinity of each other, and between mobile phones Various functions such as a function for detecting a distance may be provided in a server device connected to the base station B or the network N, and these may regulate communication between mobile phones.

  Further, when communication is restricted at the time of outgoing call or incoming call, it is preferable to display on the display unit of the mobile phone that the communication restriction is performed or notify the user by voice notification. In addition, many current mobile phones can send and receive e-mails in addition to calls. However, communication may be restricted only for calls or for all communications including e-mail transmission and reception. The communication between the communication device apparatuses may be classified, and the communication restriction may be controlled according to the classified communication. In addition, the present invention is not limited to a mobile phone, but can be applied to a PHS (Personal Handyphone System), a car phone, and other communication device apparatuses.

  Further, in the above-described embodiment, the case has been described as an example in which it is determined whether or not a plurality of mobile phones that perform communication at the time of outgoing call or incoming call are located around each other. However, communication may be restricted by determining whether or not they are located around each other not only at the time of outgoing or incoming calls but also during a call.
