  Another storage area (see FIG. 2) of the storage unit 170 will be described.

  In this embodiment, the notification pattern information storage area 172 defines information (hereinafter referred to as “notification pattern information”) for notifying the user of the terminal 100A of the positional relationship between the terminal 100A and the target terminal 100B. Stored).

  An example of the notification pattern information stored in the notification pattern information storage area 172 is shown in FIG. As illustrated, the notification pattern information is information that defines a plurality of types of notification patterns according to the separation distance between the target terminals (the own terminal 100A and the target terminal 100B).

  In the present embodiment, it is assumed that three types of notification patterns “pattern X”, “pattern Y”, and “pattern Z” are defined. The separation distance associated with each pattern is assumed that the pattern X is “within 15 meters”, the pattern Y is “15 to 30 meters”, and the pattern Z is “30 meters or more”. In the present embodiment, position notification is performed for the purpose of bringing the users closer together, so that a more severe warning is given as the separation distance increases.

  In the present embodiment, for example, a range up to a radius of 30 meters centered on the self is set as a range that can be sufficiently approached, and a warning notification is given when the distance is greater than this range. Therefore, the pattern Z associated with a separation distance of 30 meters or more is a notification pattern for such a warning notification. If the radius is within the range of 30 meters, a notice of caution is given. Accordingly, the pattern Y associated with the case where the separation distance is less than 30 meters and the distance from the closest distance of 15 meters is a notification pattern for such attention notification. Furthermore, since a range within a radius of 15 meters centered on the self is a close range that can be easily approached, a normal notification is made within this range. Therefore, the pattern X associated with the separation distance within 15 meters is such a notification pattern for normal notification. That is, a notification pattern is defined for each notification level corresponding to the separation distance.

  In each pattern, the display color and display pattern of the screen displayed on the display unit 141, the pattern of the notification sound (electronic sound) output from the notification sound generation unit 142, and the vibration operation by the motor drive unit 144 (motor 145) are displayed. Vibration patterns are specified.

  In the present embodiment, it is assumed that a radar screen is displayed as a screen showing a separation distance and a relative position between the terminal 100A and the target terminal 100B (another terminal) (details will be described later). Therefore, the “display color” defined by the notification pattern information indicates the display color when the radar screen is displayed. For example, “green” (normal color) in pattern X and “yellow” in pattern Y (caution) Color) and pattern Z are defined as “red” (warning color).

  This display color is defined according to, for example, the degree of attention to the user. That is, in the present embodiment, the mobile communication terminal 100 notifies the user of each other's position in order to bring the users closer together in a meeting or the like, so that the users (that is, the own terminal 100A and the target terminal 100B) are more separated from each other. Specify the display color that will alert you if you do this. Therefore, in this embodiment, as the separation distance increases, display colors (yellow and red) that have a more alerting effect are defined.

  Similarly, the specified items (display pattern, notification sound pattern, vibration pattern) other than the display color are also used when the users (the terminal 100A and the target terminal 100B) are further separated (when the separation distance is changed). An object is to alert the user by changing the display pattern of the radar screen, reporting an electronic sound, or performing a vibration function of a vibrator function. Therefore, the display pattern, the notification sound, and the vibrator operation are not defined in the pattern X corresponding to the closest separation distance. On the other hand, in the pattern Y corresponding to the separation distance that is separated from the separation distance associated with the pattern X, each of the notification sound and the vibrator operation is defined.

  In the pattern Z corresponding to the separation distance further apart from the separation distance corresponding to the pattern Y, the notification sound and the vibrator operation are defined similarly to the pattern Y. However, the notification sound pattern and the vibration pattern different from the pattern Y are defined. It is prescribed. In addition, display patterns that are not defined in other patterns are defined.

  That is, in the case of a report sound pattern, for example, “default ringing” (short ringing) is defined in pattern Y, whereas in pattern Z, “long ringing is longer than the default ringing” Is defined. In other words, a notification sound pattern is defined so that the user is more alerted when the distance is further away.

  In the case of the vibration pattern, for example, “default vibration” (short vibration) is defined in the pattern Y, whereas “long vibration” having a vibration period longer than the default vibration is defined in the pattern Z. That is, a vibration pattern is specified so as to alert the user more when the separation distance is further away.

  In the display pattern defined only for the pattern Z, screen blinking is defined. That is, a display pattern is specified that is more alert to the user when the separation distance is the longest.

  The own position information storage area 173 stores coordinate information (own position information) indicating the position of the mobile communication terminal 100 (own terminal 100A) acquired by the position information acquiring unit 111 from the GPS positioning unit 160.

  The target position information storage area 174 stores the position information (other terminal position information) of the target terminal 100B acquired by the position information acquisition unit 111 when the mobile communication terminal 100 operates as the own terminal 100A. An example of information recorded in the target position information storage area 174 is shown in FIG. As shown in the figure, in the target position information storage area 174, a record using a session ID assigned to each session with the target terminal 100B as a key is created, and each record includes, for example, the telephone number of the target terminal 100B, The identification information (terminal identification information) for identifying the terminal, such as an e-mail address, the position information ID assigned for each acquisition of the position information (other terminal position information) for the target terminal 100B, and the information acquired at that time Information indicating position information (position information of other terminals), acquisition date and time, and the like is recorded. Here, the location information ID indicates the number of receptions of location information of other terminals in the session.

  The relative position information storage area 175 stores information indicating the separation distance calculated by the separation distance calculation unit 112 and the relative position calculated by the relative position calculation unit 113. An example of information recorded in the relative position information storage area 175 is shown in FIG. As shown in the figure, in the relative position information storage area 175, a record is created using the session ID as a key for the other terminal position information of the target terminal 100B that is the basis of the calculation, and each record is used for the calculation. Information indicating the calculated relative position and separation distance is recorded for each position information ID assigned to the other terminal position information. Here, the relative position indicates the direction of the target terminal 100B viewed from the mobile communication terminal 100. That is, the relative position information and the separation distance information calculated each time the other terminal position information is received in the session are recorded.

  In addition, each said structure is a main structure required in order to implement | achieve this invention with the mobile communication terminal 100, About the other structure required as a mobile communication terminal, it is equipped as needed. And

  The operation executed by the mobile communication terminal 100 (the own terminal 100A and the target terminal 100B) having the above configuration will be described below. As described above, in the present embodiment, the own terminal 100A notifies the user of the positional relationship between the own terminal 100A and the target terminal 100B. In this case, a session performed between the own terminal 100A and the target terminal 100B will be described with reference to the flowchart shown in FIG.

  Here, the own terminal 100A, which is the own terminal, executes terminal position display processing for displaying the positional relationship with the target terminal 100B, and the target terminal 100B (another terminal) responds to a request from the own terminal 100A. By executing position information transmission processing for transmitting position information, a session between the terminal 100A and the target terminal 100B is performed. In FIG. 5, the terminal position display process executed by the terminal 100A is shown in the left flowchart, and the position information transmission process executed by the target terminal 100B (another terminal) is shown in the right flowchart.

  The session is started by a terminal position display process (left side in FIG. 5) on the own terminal 100A side. This terminal position display process is started when the user of the terminal 100A operates the operation unit 130 and instructs the start of the terminal position display operation.

  When the terminal position display process is started in the own terminal 100A that is the own terminal, the output control unit 115 of the own terminal 100A causes the user to designate the target terminal 100B that is the target of position recognition. Is generated and displayed on the display unit 141 (step S101).

  The user operates the operation unit 130 and inputs information specifying the desired target terminal 100B. Here, for example, information (terminal identification information) for specifying the target terminal 100B such as a telephone number or an e-mail address assigned to the target terminal 100B is input.

  When the terminal identification information is input to the control unit 110 by the operation unit 130, the position information acquisition unit 111 controls the data communication control unit 124 and starts communication with the target terminal 100B based on the input terminal identification information. Then, information (hereinafter referred to as “position notification request information”) requesting transmission of the position information of the target terminal 100B (other terminal position information) is transmitted to the target terminal 100B (step S102).

  In this case, in the target terminal 100B, the data communication control unit 124 receives the position notification request information transmitted by the terminal 100A by the position information transmission process shown on the right side of FIG. 5 (step S201). As a result, communication between the own terminal 100A and the target terminal 100B is started, and the position information acquisition unit 111 determines whether or not the automatic transmission setting is set for the target terminal 100B. To do.

  The automatic transmission setting is a setting as to whether or not the mobile communication terminal 100 automatically transmits position information in response to a position notification request from another mobile communication terminal 100. The mobile communication terminal Set by 100 users. In this embodiment, the automatic transmission setting is set by a flag (automatic transmission flag). In this case, the flag value “1” indicates the “automatic transmission” setting, and the flag value “0” indicates the “not automatic transmission” setting. Therefore, the position information acquisition unit 111 determines whether or not automatic transmission is set by determining whether or not the automatic transmission flag is 1 (step S202). It is assumed that the flag value of the automatic transmission flag is stored in the storage unit 170.

  Here, when the flag value is “0” (step S202: No), the output control unit 115 generates a “permission / rejection selection screen” for allowing the user to select whether to permit transmission of the position information, and displays it on the display unit 141. (Step S203). The permission / refusal selection screen includes a message inquiring whether or not the requesting mobile communication terminal 100 (in this case, the own terminal 100A) may be notified of the position information of itself (in this case, the target terminal 100B), and Answers to (for example, “Yes” and “No”) are displayed in a selectable manner. The user operates the operation unit 130 to select a desired answer.

  If the transmission of the position information is rejected by the user's operation (step S204: No), the process is terminated as it is.

  On the other hand, when transmission of position information is permitted by the user's operation (step S204: Yes), or when the flag value of the automatic transmission flag is “1” (step S202: Yes), position information acquisition The unit 111 controls the GPS positioning unit 160 to perform a position positioning operation, and acquires position information indicating the position of the target terminal 100B (own position information of the target terminal 100B) (step S205).

  The position information acquisition unit 111 cooperates with the data communication control unit 124 to transmit the own position information acquired by the positioning operation in step S205 to the own terminal 100A in communication (step S206). Thereby, the other terminal position information for the own terminal 100A is transmitted from the target terminal 100B to the own terminal 100A.

  In this case, in the terminal location display process shown on the left side of FIG. 5, in the own terminal 100 </ b> A, the data communication control unit 124 receives the position information transmitted by the target terminal 100 </ b> B and inputs it to the control unit 110. In this case, the position information acquisition unit 111 stores the input position information of the target terminal 100B in the target position information storage area 174. That is, the position information acquisition unit 111 acquires the position information (other terminal position information) of the target terminal 100B (other terminal) and stores it in the target position information storage area 174 (step S103).

  When the position information (the other terminal position information) of the target terminal 100B is acquired, the own terminal 100A executes a notification process for notifying the user of the position of the target terminal 100B (step S150). This notification process will be described with reference to the flowchart shown in FIG.

  When the processing is started, the position information acquisition unit 111 of the own terminal 100A controls the GPS positioning unit 160, acquires own position information indicating the position of the own terminal 100A, and stores it in the own position information storage area 173 ( Step S151).

  When the own position information is stored, the position information (other terminal position information) of the target terminal 100B stored in the target position information storage area 174 in step S103, and the self (own terminal 100A) stored in the own position information storage area 173 in step S151. ) Position information (own position information), the relative position calculation unit 113 calculates the relative position between the own terminal 100A and the target terminal 100B and stores it in the relative position information storage area 175 (step S152). .

  Here, the direction of the target terminal 100B viewed from the own terminal 100A is calculated as a relative position. That is, since both the position information of the target terminal 100B (the other terminal position information) and the own position information of the own terminal 100A are indicated by the coordinate information acquired by the GPS function, the relative position calculation unit 113 From the coordinates, the direction of the target terminal 100B viewed from the own terminal 100A is calculated.

  When the relative position with respect to the target terminal 100B is calculated, the position information (the other terminal position information) of the target terminal 100B stored in the target position information storage area 174 in step S103 and the own position information storage area 173 in step S151. Based on the position information (own position information) of the terminal 100A, the separation distance calculation unit 112 calculates the separation distance between the terminal 100A and the target terminal 100B and stores it in the relative position information storage area 175. (Step S153). Here, based on the coordinate information constituting each of the own position information and the other terminal position information, the separation distance between the own terminal 100A and the target terminal 100B (hereinafter referred to as “calculated separation distance D”) is calculated.

  When the separation distance is calculated, the notification pattern selection unit 114 compares the reference separation distance defined by the notification pattern information stored in the notification pattern information storage area 172 with the calculated separation distance D, and the comparison result. Select a notification pattern according to. Here, it is assumed that the reference separation distance and the calculated separation distance D of each pattern are compared in the order of the pattern X, the pattern Y, and the pattern Z.

  The notification pattern selection unit 114 first compares the reference separation distance of the pattern X (hereinafter referred to as “reference separation distance X”) with the calculated separation distance D. As shown in FIG. 4A, in this embodiment, the separation distance within 15 meters and the pattern X are associated with each other. Therefore, the reference separation distance X of the pattern X is 15 meters. Then, the notification pattern selection unit 114 compares the calculated separation distance D with the reference separation distance X, and determines whether or not “D ≦ X” is satisfied (step S154). That is, it is determined whether or not the calculated separation distance D is within 15 meters.

  Here, when the calculated separation distance D is within the specified range for the pattern X (that is, D ≦ X) (step S154: Yes), the notification pattern selection unit 114 selects the pattern X as a notification pattern (step S154). S155). On the other hand, if D> X and the pattern X is not within the specified range (step S154: No), the notification pattern selection unit 114 compares the reference separation distance and the calculated separation distance D for the next pattern Y.

  Since the separation distance corresponding to the pattern Y is “15 to 30 meters” (see FIG. 4A), 15 meters and 30 meters are compared as the reference separation distance. Here, a reference separation distance indicating 15 meters is defined as a reference separation distance Y1, and a reference separation distance indicating 30 meters is defined as a reference separation distance Y2. The notification pattern selection unit 114 compares these with the calculated separation distance D, and determines whether or not “Y1 <D <Y2” is satisfied (step S156).

  When the calculated separation distance D is within the specified range for the pattern Y (that is, Y1 <D <Y2) (step S156: Yes), the notification pattern selection unit 114 selects the pattern Y as the notification pattern (step S157). ). On the other hand, if D ≧ Y2 and it is not within the prescribed range of the pattern X and the pattern Y (step S156: No), the notification pattern selection unit 114 corresponds to the pattern Z and selects the pattern Z as the notification pattern ( Step S158).

  In this way, when a notification pattern is selected, notification processing corresponding to the selected pattern is executed by the output control unit 115 or the like. That is, when the pattern X is selected in step S155, the pattern X notification process is executed (step S300), and when the pattern Y is selected in step S157, the pattern Y notification process is executed (step S400). ) When the pattern Z is selected in step S158, the pattern Z notification process is executed (step S500). Each process will be described below.

  First, the pattern X notification process will be described with reference to the flowchart shown in FIG. In the present embodiment, the positional relationship between the own terminal 100A and the target terminal 100B is displayed on the radar screen. Therefore, when the process is started, the output control unit 115 controls the display unit 141 to display a concentric radar screen as a guide for the separation distance on the display unit 141 as shown in FIG. S301). On the concentric circles of the radar screen, for example, a cross line as shown in FIG. 10A is superimposed, and thereby directions of east, west, south, and north are indicated. In the example of FIG. 10A, it is assumed that the upper side of the screen indicates north (N), the lower side of the screen indicates south (S), the right side of the screen indicates east (E), and the left side of the screen indicates west (W). .

  The output control unit 115 further controls the display unit 141, and as shown in FIG. 10B, the radar screen in which an object image (hereinafter referred to as “object A”) indicating the terminal 100A is displayed in step S301. It displays on the center position of a concentric circle (step S302).

  Next, the output control unit 115 accesses the relative position information storage area 175, the relative position information of the target terminal 100B with respect to the own terminal 100A calculated in step S152, and the own terminal 100A and the target calculated in step S153. Information on the distance from the terminal 100B is acquired (step S303).

  Then, an object image (hereinafter referred to as “object B”) showing the target terminal 100B as shown in FIG. 11 is displayed on the radar screen (step S304). Here, the object B is displayed on the radar screen so as to be in the direction of the target terminal 100B as viewed from the actual terminal 100A.

  In this case, as illustrated in FIG. 11, the output control unit 115 displays an arrow line indicating the direction from the object A to the object B on the radar screen. This arrow straight line has, for example, a drawing attribute corresponding to the separation distance. For example, a thicker arrow straight line is displayed as the separation distance increases.

  Next, the output control unit 115 accesses the notification pattern information storage area 172 and acquires pattern information of the currently selected notification pattern. Here, since the pattern X is selected, pattern information defining the pattern X is acquired (step S305). Since only the display color is defined in the pattern X, the output control unit 115 controls the display unit 141 to control the display color of the radar screen displayed in step S301. Here, for example, as shown in FIG. 11, the concentric circles on the radar screen are displayed in green display color (step S306), and the process is terminated. In this case, as shown in FIG. 11, a separation distance indicated by the acquired separation distance information, a message indicating that the distance is close, and the like are displayed on the display unit 141.

  That is, when the separation distance is 15 meters or less, the radar screen is displayed in the normal green color according to the regulation of the pattern X, and the normal notification without the output of the notification sound or the vibration operation is performed.

  Next, the pattern Y notification process executed when the pattern Y is selected will be described with reference to the flowchart shown in FIG.

  First, as in the case of the pattern X notification process, the output control unit 115 displays a concentric circle radar screen serving as a guide for the separation distance and direction on the display unit 141 (see step S401 (see FIG. 10A)). The object A is displayed at the center (step S402 (see FIG. 10B)). When the relative position information and the separation distance information are acquired from the relative position information storage area 175 (step S403), the object B is displayed on the radar screen of the display unit 141 based on the acquired relative position information and the separation distance information. (Step S404). In this case, the output control unit 115 displays an arrow line indicating the direction from the object A to the object B on the radar screen, but displays a thicker arrow line than the pattern X, and the separation distance is relatively large. Is expressed by an intuitive visual display.

  Next, the output control unit 115 accesses the notification pattern information storage area 172, and acquires pattern information of the pattern Y (step S405). The output control unit 115 performs display color control based on the acquired pattern information. In the pattern Y, the attention color yellow is defined as the display color, so the output control unit 115 controls the display unit 141 to display the concentric circles of the radar screen in the yellow display color as shown in FIG. (Step S406). Here, as shown in FIG. 12, the display unit 141 displays a separation distance indicated by the acquired separation distance information, a message indicating that it is close to a non-displayable area (details will be described later), and the like.

  Unlike the pattern X, the pattern Y also defines a notification sound and a vibration operation. Therefore, the output control unit 115 first performs notification sound output control (voice control). In this case, the output control unit 115 controls the notification sound generating unit 142 based on the notification pattern of the notification sound defined by the pattern Y, and outputs the notification sound from the notification sound speaker 143. That is, an electronic sound having the sounding cycle of the default sounding sound (short sounding sound) defined by the pattern Y is generated and output to the notification sound generating unit 142 (step S407).

  Further, the output control unit 115 performs vibration control (vibrator control) of the vibrator function based on the definition of the pattern Y. In this case, the output control unit 115 controls the motor driving unit 144 based on the vibration pattern of the vibration operation defined in the pattern Y to cause the motor 145 to perform the vibration operation. Here, the motor 145 is caused to generate a vibration operation having a vibration period of the default vibration (short vibration) defined by the pattern Y (step S408), and the process ends.

  Next, the pattern Z notification process will be described with reference to the flowchart shown in FIG. Here, as in the pattern Y notification process, the concentric radar screen and the object A are displayed on the display unit 141 by the display control of the output control unit 115 (step S501).

  Here, the upper limit of the maximum separation distance that can be displayed on the concentric radar screen displayed in the present embodiment is 30 meters (displayable range). Accordingly, the object B can be displayed on the radar screen at the separation distance in which the pattern X or the pattern Y is selected (displayable range), but in the case of the separation distance in which the pattern Z is selected, an accurate separation is possible. The object B indicating the distance cannot be displayed on the radar screen (out of displayable range). Therefore, when the pattern Z is selected, when the output control unit 115 acquires the relative position information and the separation distance information from the relative position information storage area 175 (step S502), the radar edge of the direction based on the relative position information The object B is displayed on (Step S503).

  Next, the output control unit 115 acquires pattern information defined in the pattern Z from the notification pattern information storage area 172 (step S504), and performs display color control. In the pattern Z, the warning color red is defined as the display color. Therefore, the output control unit 115 controls the display unit 141 to display the red display color within the concentric circles of the displayed radar screen as shown in FIG. Is displayed (step S505). Further, as shown in FIG. 13, a separation distance indicated by the acquired separation distance information, a message indicating that it is out of the displayable range, and the like are displayed on the display unit 141.

  Here, unlike the other patterns, the pattern Z defines a display pattern, so the output control unit 115 performs display pattern control. In the pattern Z, blinking display is defined as a display pattern, so the output control unit 115 blinks the screen by controlling the backlight of the display unit 141, for example (step S506).

  Further, the output control unit 115 performs voice control and vibrator control based on the pattern information of the pattern Z. That is, based on the notification sound pattern defined in the pattern Z, the notification sound generator 142 is controlled to output a notification sound that becomes a long sound from the notification sound speaker 143 (step S507). Further, based on the vibration pattern defined in the pattern Z, the motor driving unit 144 is controlled to generate a long vibration from the motor 145 (step S508). That is, a notification sound or vibration different from the case where the pattern Y is selected is output.

  Here, the output control unit 115 of the own terminal 100A performs a display operation based on only the position information acquired for the first time in the session with the target terminal 100B based on the position information ID of the relative position information acquired in step S502. It is determined whether or not there is (step S509). That is, in the present embodiment, the position information may be acquired a plurality of times in a session with the target terminal 100B by a process described later. Therefore, whether or not position information has been acquired a plurality of times in the same session is determined based on the determination in step S509.

  When the process is based on the position information acquired for the first time in the same session (step S509: Yes), the output control unit 115 displays an arrow line indicating the direction based on the relative position information acquired in step S502 on the radar screen. (Step S510). That is, an arrow straight line indicating the direction of the target terminal 100B at the current time is displayed on the radar screen.

  On the other hand, when the position information acquisition in the same session has been performed a plurality of times (step S509: No), the relative position calculation unit 113 is requested to estimate the movement direction of the target terminal 100B. The relative position calculation unit 113 calculates a movement trajectory of the target terminal 100B based on the position information acquired a plurality of times in response to a request from the output control unit 115, and calculates an estimated movement direction vector of the target terminal 100B. Then, the estimated movement position of the target terminal 100B is calculated. The relative position calculation unit 113 generates relative position information indicating the calculated estimated movement position as a relative position when viewed from the terminal 100A, and notifies the output control unit 115 of the relative position information (step S511).

  The output control unit 115 displays an arrow line indicating the direction of the relative position indicating the estimated movement position calculated by the relative position calculation unit 113 on the radar screen (step S512), and ends the process. That is, when the target terminal 100B is out of the displayable range, the object B is displayed at the outermost edge of the radar concentric circle, and the direction of the estimated moving position is displayed by an arrow straight line. Note that the arrow straight line displayed when the pattern Z is selected is displayed thicker than the arrow straight line displayed when the pattern Y is selected. To express.

  When the notification process corresponding to the selected notification pattern is executed, the process returns to the notification process flow shown in FIG.

  Here, as shown in FIGS. 10 to 13, a “return” button, a “map display” button, and an “end” button are displayed on each notification screen. Each button is associated with a predetermined button constituting the operation unit 130, and when the user operates the button, execution of the contents indicated by the button is instructed.

  When the position display of the target terminal 100B is further continued, the user operates the operation unit 130 corresponding to the “return” button. When it is desired to display a map showing the route from the target terminal 100B currently displayed on the radar screen to the own terminal 100A, the operation unit 130 corresponding to the “map display” button is operated. On the other hand, when the position display of the target terminal 100B is to be ended, the operation unit 130 corresponding to the “END” button is operated.

  When the user operates the operation unit 130, an input signal indicating which button has been operated is input from the operation unit 130 to the control unit 110. The control unit 110 determines a user instruction based on the input signal.

  When “map display” is instructed (step S159: Yes), a map screen display process for displaying a map screen is executed by the map information acquisition unit 116 or the like (step S600). Details of this map screen display processing will be described later.

  On the other hand, when an instruction other than “map display” is given (step S159: No), the process returns to the flow of the terminal position display process shown in FIG. Here, when the user's instruction is “end” (step S104: Yes), the position information acquisition unit 111 requests the target terminal 100B to end the position information transmission operation (step S105). Here, in cooperation with the data communication control unit 124, transmission end request information for requesting the end of the transmission operation is transmitted to the target terminal 100B in communication. Thereby, the end of the position information transmission operation is requested to the target terminal 100B, and the process is ended.

  When “return” is instructed (step S104: No), the process returns to step S103 of the terminal position display process and the above-described process is repeated. That is, in the same session, the position information of the target terminal 100B is acquired a plurality of times, and the position of the terminal 100A and the target terminal 100B is output as needed by detecting the position of the terminal as needed.

  The operation of the target terminal 100B when the continuation of position display is instructed on the own terminal 100A side will be described with reference back to FIG. Here, the operation of the target terminal 100B will be described with reference to the flowchart of the position information transmission process shown on the right side of FIG.

  In the target terminal 100B, when the position information is transmitted to the terminal 100A in step S206, the position information acquisition unit 111 cooperates with the data communication control unit 124 to determine whether transmission end request information is transmitted from the terminal 100A. It discriminate | determines (step S207). When the terminal 100A transmits the transmission end request information in step S106 shown on the left side of FIG. 5, it is received by the data communication control unit 124 of the target terminal 100B and input to the control unit 110 (step S207: Yes). In this case, since the end of the position information transmission operation is requested by the terminal 100A, the position information acquisition unit 111 of the target terminal 100B ends the position information transmission process as it is.

  On the other hand, when the transmission end request information is not transmitted from the own terminal 100A (step S207: No), the position information acquisition unit 111 determines whether a predetermined time has elapsed since the previous position information transmission (step S208). When the predetermined time has elapsed (step S207: Yes), the process returns to step S205, and position information indicating the current position of the target terminal 100B is transmitted to the own terminal 100A.

  That is, the target terminal 100B transmits position information indicating its own position to the own terminal 100A every predetermined time until there is a transmission end request from the own terminal 100A.

  That is, until the user of the own terminal 100A instructs the end, the own terminal 100A acquires the position information (other terminal position information) of the target terminal 100B and the own position information (own position information) at any time, and the acquired position information The corresponding notification process is performed. Therefore, when each mobile communication terminal 100 is moving, the movement is reflected on the radar screen as needed. Then, when the separation distance changes due to the movement, the corresponding notification pattern changes accordingly. In the present embodiment, when the separation distance is greater than or equal to the predetermined range, the notification is switched to alerting for more attention.

  Here, in the notification process shown in FIG. 6, the map display process executed when the user of the terminal 100A instructs “map display” (step S159: Yes) will be described with reference to the flowchart shown in FIG. To do. This map display process is executed by the map information acquisition unit 116 of the terminal 100A.

  When the process is started, the map information acquisition unit 116 accesses the own position information storage area 173, and acquires the position information (own position information) of the own terminal 100A acquired most recently (step S601).

  Next, the map information acquisition unit 116 accesses the target position information storage area 174, and acquires the position information (other terminal position information) of the target terminal 100B acquired most recently (step S602).

  When the position information of each mobile communication terminal 100 is acquired, the map information acquisition unit 116 accesses a website (map service site) that provides map information in cooperation with the data communication control unit 124 (step S603). Here, it is assumed that address information (for example, URL (Uniform Resource Locator)) indicating such a website is stored in the storage unit 170 in advance, and the map information acquisition unit 116 designates such an address. Thus, access is made by the data communication function (Internet access function) of the terminal 100A.

  When accessing the map service site, the map information acquisition unit 116 starts from the own position indicated by the own position information acquired in step S601, and the position of the target terminal 100B indicated by the position information (other terminal position information) acquired in step S602. Is sent to the map service site as a destination (step S604).

  The map service site receives the location information transmitted by the terminal 100A, creates map information indicating the route from the designated departure point to the destination, and transmits the map information to the terminal 100A. The creation of map information in this case is assumed to be realized using a known route search method or the like.

  In the own terminal 100A, the data communication control unit 124 receives the map information transmitted from the map service site (step S605) and inputs it to the control unit 110. The map information acquisition unit 116 instructs the output control unit 115 to display the input map information. The output control unit 115 controls the display unit 141 in accordance with an instruction from the map information acquisition unit 116, and displays a map screen as shown in FIG. 15 (step S606).

  As shown in the figure, in addition to displaying the acquired map information, a “return” button, an “end” button, and the like associated with a predetermined button of the operation unit 130 are displayed on the map screen. When returning from the map screen display to the radar screen display, the operation unit 130 corresponding to the “return” button is operated, and when ending the position display, the “end” button is operated. When the user selects a button for designating a desired operation, execution of the operation is instructed. The control unit 110 determines a user instruction based on an input signal from the operation unit 130.

  Here, when “end” is designated (step S607: Yes), the control unit 110 ends all the processes related to position display. On the other hand, when “return” is instructed (step S607: No, S608: Yes), the control unit 110 ends the map display process and returns to the notification process flow shown in FIG. In this case, the process returns to the terminal position display processing flow shown in FIG. 5 as it is, and the position display operation by radar display is continued.

  As described above, by applying the present invention as in the above-described embodiment, it is possible to notify the user of the desired partner's position at any time using a terminal device such as a mobile communication terminal. In this case, since a different notification method is selected depending on the distance from the opponent, for example, when the user is further away in a scene where the opponent must be approached, the user can be notified by a method of alerting it can. That is, since the notification pattern is changed according to the change in the separation distance, it is possible to effectively alert the user. In this case, since the user can be alerted with the display color and display pattern of the display screen, the user can easily know that the user has been separated. In addition, since attention is also given by means other than the display, even if the user is not always gazing at the display screen, the user can be alerted by a notification sound, vibrator vibration, or the like.

  Moreover, since the map information on which the route is displayed can be acquired using the acquired position information, the route for reaching the opponent position can be easily known.

  The said embodiment is an example and the application range of this invention is not restricted to this. That is, various applications are possible, and all embodiments are included in the scope of the present invention.

  For example, the notification pattern information shown in the above embodiment is an example, and the setting contents are arbitrary. That is, the types of notification patterns are not limited to three, and are arbitrary, and the operation of the set mobile communication terminal 100 is also arbitrary. For example, in the above embodiment, the sounding cycle of the notification sound and the vibration cycle of the vibrator vibration are defined, but the volume of the notification sound, the vibration intensity of the vibrator, and the like may be set.

  Further, these operations may be selectively executed. In this case, for example, a notification operation may be performed according to a call mode set in the mobile communication terminal 100. For example, when the manner mode is set, even if the notification sound pattern is set, the notification mode may be operated without outputting the notification sound.

  Moreover, in the said embodiment, although the positional relationship of the mobile communication terminal 100 shall be displayed on a radar screen, as long as it can alert | report a positional relationship, you may alert | report on arbitrary screens. Also, the displayable range on the radar screen can be set arbitrarily. In the above embodiment, the direction of the other terminal with respect to itself is indicated by an arrow straight line.
