<Configuration>
An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is a diagram showing the configuration of a system according to an embodiment of the present invention. This system includes a plurality of mobile communication terminals 100, a map server device 200, and a network NW. The mobile communication terminal 100 is a wireless terminal that can be carried by a user and performs wireless communication, such as a mobile phone, a communication terminal that can be connected to a wireless local area network (LAN), or a laptop computer having a wireless function. It is. The map server device 200 is a server device that accumulates map data representing a map. The network NW is a communication network including a mobile communication network such as a mobile phone network and a wireless LAN, and a fixed communication network such as the Internet. In this system, the mobile communication terminals 100 or the mobile communication terminal 100 and the map server device 200 communicate via the network NW.

  The mobile communication terminals 100 are owned by different users, and when these users meet at a destination, they guide to that destination. In the mobile communication terminal 100, there are two types of operation modes related to guidance to a destination: a guidance mode and another person guidance support mode. Specifically, in the guidance mode, the mobile communication terminal 100 displays the position and destination determined by the terminal on the map represented by the map data acquired from the map server device 200 via the network NW, Guidance to the destination is given to the user who owns the terminal. On the other hand, the other person guidance support mode is an operation mode that can be taken only by the mobile communication terminal 100 possessed by the user who has already arrived at the destination. The mobile communication terminal 100 in this other person guidance support mode provides support for guidance that the mobile communication terminal 100 possessed by another user who has not yet arrived at the destination has given to the user in the guidance mode (other party (Referred to as guidance assistance). The term “support” as used herein refers to providing information used for guidance to the mobile communication terminal 100 that provides guidance to the destination for other users.

  FIG. 2 is a block diagram showing a hardware configuration of mobile communication terminal 100. In addition to the control unit 11, the storage unit 12, the display unit 13, the operation unit 14, the network communication unit 15, the short-range wireless communication unit 16, the positioning unit 17, and the electronic compass 18, the mobile communication terminal 100 measures time and date. A vibration part (not shown) for notifying by means and vibration is provided, and these parts are connected to each other via a bus 19. The control unit 11 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), and a ROM (Read Only Memory). The CPU controls each unit of the mobile communication terminal 100 by reading a computer program stored in the ROM or the storage unit 12 and loading it into the RAM for execution.

  The display unit 13 includes a display body such as a liquid crystal display and a memory such as a VRAM (Video Random Access Memory), and displays various images under the control of the control unit 11. The operation unit 14 has a plurality of keys. When these keys are operated by the user, the operation unit 14 supplies a signal corresponding to the operation content to the control unit 11. The control unit 11 determines the operation content based on this signal and performs processing. The network communication unit 15 communicates with another mobile communication terminal 100 or the map server device 200 via a mobile communication network included in the network NW under the control of the control unit 11. The short-range wireless communication unit 16 performs short-range wireless communication with the short-range wireless communication unit 16 of another mobile communication terminal 100 under the control of the control unit 11 in the above-described other person guidance support mode. The short-range wireless communication method is, for example, Bluetooth, and the maximum communicable distance that indicates how far the mobile communication terminals 100 can communicate with each other at a maximum is 10 m. The positioning unit 17 performs positioning by the GPS method, and generates position information in which the position specified by the positioning is expressed by latitude and longitude. Hereinafter, when the current position is simply referred to, it represents the current position of the mobile communication terminal 100. Moreover, since the user possesses the mobile communication terminal 100 when performing destination guidance, this current position is synonymous with the current position of the user. The electronic compass 18 includes a magnetic sensor that detects geomagnetism, and supplies the detection result of the magnetic sensor to the control unit 11.

  The storage unit 12 is a non-volatile storage unit such as an EEPROM (Electrically Erasable and Programmable ROM) or flash memory, and stores mail address data 121, short-range wireless address data 122, waiting data 123, various threshold values, and programs. . The mail address data 121 is data in which a user ID that uniquely identifies each user of the mobile communication terminal 100 and a mail address assigned to each mobile communication terminal 100 are associated on a one-to-one basis. The short-range wireless address data 122 is data in which each user ID and the short-range wireless address assigned to each mobile communication terminal 100 are associated with each other on a one-to-one basis. The short-range wireless address is identification information assigned to the mobile communication terminal 100 for performing short-range wireless communication in short-range wireless communication. The waiting data 123 is data related to waiting between users.

  FIG. 3 is a diagram showing the contents of the mail address data 121. The mail address data 121 includes a plurality of items such as “user ID”, “user name”, “mail address”, and “waiting target flag”. As described above, the “user ID” is information that uniquely identifies each user of the mobile communication terminal 100, and is, for example, a combination of eight letters. The “user name” is a name that identifies each user of the mobile communication terminal 100. The “mail address” is a mail address assigned to each mobile communication terminal 100 as described above. The “waiting target flag” is a flag indicating whether or not each user is set as a waiting partner, “1” is a waiting target, and “0” is not a waiting target. . When the user performs setting for destination guidance through the operation unit 14 in the procedure described later, the control unit 11 sets “waiting” for the user who is set as the waiting partner according to the setting content. The “target flag” is set to “1”, and the “waiting target flag” is set to “0” for a user who is not set as the waiting partner. As shown in FIG. 3, the mail address data 121 includes a plurality of sets of “user ID”, “user name”, “mail address”, and “waiting target flag”.

  When waiting is performed, the control unit 11 causes the storage unit 12 to store the mail address by exchanging the mail address with the partner user who performs the waiting in advance by the following method. For example, the control unit 11 performs an infrared function (not shown) between the mobile communication terminal 100 that is its own terminal and the mobile communication terminal 100 possessed by the other user who is waiting according to a user operation using the operation unit 14. By performing infrared communication, the respective mail addresses are exchanged, and the “mail address” of the other user is stored in the storage unit 12. As another method, the control unit 11 stores the mail address in the storage unit 12 by directly inputting the mail address of the other user who is to wait for using the operation unit 14. The method for exchanging e-mail addresses may be a method other than the above as long as it can be exchanged in advance when waiting.

  FIG. 4 is a diagram showing the contents of the short-range wireless address data 122. The short-range wireless address data 122 includes a plurality of items such as “user ID”, “user name”, “short-range wireless address”, and “waiting target flag”. The “user ID”, “user name”, and “waiting target flag” are as described above. As described above, the “near field wireless address” is identification information assigned to each mobile communication terminal 100, and specifically, for example, a MAC (Media Access Control) address as shown in FIG. . As shown in FIG. 3, the short-range wireless address data 122 includes a plurality of sets of “user ID”, “user name”, “short-range wireless address”, and “waiting target flag”.

  The control unit 11 causes the storage unit 12 to store the short-range wireless address when the user exchanges the short-range wireless address in advance with the partner user who is to wait. Specifically, when the user performs setting for destination guidance using the operation unit 14 in a procedure as described later, the control unit 11 refers to the mail address data 121 and the other party to wait for The user's mail address is specified, and the short-range wireless address of the terminal is sent to the mail address. For example, when two users make a setting for destination guidance while meeting each other, short-range wireless addresses assigned to the respective mobile communication terminals 100 are exchanged with each other. The control unit 11 causes the storage unit 12 to store the short-range wireless address exchanged in this way. As another method, in accordance with a user operation using the operation unit 14, the control unit 11 is connected between the mobile communication terminal 100 that is its own terminal and the mobile communication terminal 100 possessed by the other user who is waiting. By causing the infrared function (not shown) to perform infrared communication, the short-range wireless addresses of each other user may be exchanged, and the short-range wireless address of the partner user may be stored in the storage unit 12. The method for exchanging the short-range wireless address may be a method other than the above as long as it can be exchanged in advance when the meeting is performed.

  FIG. 5 is a diagram showing the contents of the waiting data 123. The meeting data 123 includes a plurality of items such as “meeting ID”, “meeting user”, “destination”, “meeting date / time”, “arrived user”, and “arrival date / time”. The “waiting ID” is information for uniquely identifying each waiting performed using the mobile communication terminal 100, and is, for example, a combination of eight digits. The “meeting user” is a user name of a user who performs the meeting, and includes user names of at least two users. The “destination” is a place where the users meet and is the name of an actually existing building or station, or the address of the address. “Meeting date and time” represents the date and time of meeting. The “arrived user” is the user name of a user who has already arrived at the destination among the waiting users. “Arrival date and time” is the date and time when the arrived user arrives at the destination.

<Operation>
FIG. 6 is a schematic diagram for explaining an outline of destination guidance. The user 300 moves toward the destination 400 according to the destination guidance by the mobile communication terminal 100. The destination guidance by the mobile communication terminal 100 includes guidance for the user to the destination by different methods. Specifically, guidance by the positioning unit 17 and guidance by the electronic compass 18 are included. The relationship between the order of these guidances and the distance to the destination will be explained. First, guidance is provided by the positioning unit 17 when the destination is far away, and switching to guidance by the electronic compass 18 is made when the destination is approached to some extent. It is done. Hereinafter, the range in which guidance is provided by the positioning unit 17 is referred to as a GPS zone, and the range in which guidance is provided by the electronic compass 18 is referred to as an electronic compass zone, and the guidance from the positioning unit 17 is changed to guidance by the electronic compass 18. The switching timing is called switching timing. Within the GPS range, the control unit 11 causes the display unit 13 to display a map for notifying the user of the road from the current position specified by the positioning unit 17 to the destination 400, and the user 300 refers to the map image. However, it moves toward the destination 400. On the other hand, in the electronic compass area, the control unit 11 causes the display unit 13 to display an image simulating a so-called azimuth compass indicating the direction in which the destination 400 is located based on the detection result of the electronic compass 18. To the destination 400 while referring to FIG.

  There are the following two methods for determining the switching timing described above. The first method of determining the timing is that when the control unit 11 determines that the distance between the destination 400 and the current position is shorter than a predetermined distance (here, 10 m), the switching timing is used. is there. This method of determining the switching timing occurs when there is no user who has arrived at the destination 400. Here, the predetermined distance described above can be arbitrarily set by the user 300, but is preferably a distance that allows the user to visually confirm the destination. This is because even if the guidance is switched to the guidance by the electronic compass 18 at a point far away from the destination so that the destination cannot be visually confirmed, the guidance is merely a direction to the destination. This is because there is a high possibility that it does not play a role of guidance when there is an obstacle in the case. For example, if the distance is within the range of 10 m to 100 m, the destination can be visually confirmed even if there are some obstacles. Therefore, it is desirable to determine the predetermined distance described above within this range. This predetermined distance is stored in the storage unit 12 as the first threshold value. Thus, the guidance by the positioning unit 17 and the guidance by the electronic compass 18 are switched according to the distance from the own terminal to the destination.

  Next, the second method of determining the timing is to enable short-range wireless communication between the mobile communication terminal 100 of the own terminal and the mobile communication terminal 100 possessed by another user who has arrived at the destination first. This timing is referred to as a switching timing. This method of determining the switching timing occurs when there is a user who has arrived at the destination 400 first. As described above, since the maximum communicable distance of the short-range wireless communication unit 16 is 10 m, when the switching timing is determined in this way, the distance between the mobile communication terminal 100 and the destination is approximately 10 m. ing.

  FIG. 7 is a diagram showing a setting screen displayed on the display unit 13 when setting for destination guidance is performed. When the user starts a destination guidance program using the mobile communication terminal 100, the control unit 11 causes the display unit 13 to display a setting screen as shown in FIG. In this setting screen, the user uses the operation unit 14 to set a meeting partner, a destination serving as a meeting place, and a meeting date and time. As shown in FIG. 7, the user uses the operation unit 14 to select a meeting partner from user names displayed in a list format. At this time, the user name displayed in the list is the user name included in the mail address data 121. Note that the method of setting the waiting partner is not limited to the list format, and a plurality of waiting partners may be simultaneously selected and set using a check box format.

  In addition, the user sets the destination by directly inputting a character string corresponding to the destination into the text box using the operation unit 14. As shown in FIG. 7, this character string may be the name of an actually existing building such as “Sky Tree”, the name of a station, or the address of an address. In addition to the method of setting the destination, it is also possible to set the point selected by the user using the operation unit 14 as the destination from the map image displayed by pressing the “reference” button. It is. In addition, the user sets the waiting date and time by directly inputting the date and time for waiting in the text box using the operation unit 14. In this text box, the format of the character string representing the date and time is automatically displayed, and the user can set the waiting date and time by selecting the date and time using the operation unit 14. When the user presses the “OK” button after setting the meeting partner, the destination, and the meeting date and time as described above, the control unit 11 refers to the mail address data 121 and sets the waiting time set as described above. The short-range wireless address of the terminal is sent to the mail address of the user who is the other party. In this manner, short-range wireless addresses are exchanged between users who are waiting. Further, the control unit 11 causes the storage unit 12 to store the meeting partner, the destination, and the meeting date and time set as described above as the meeting data 123 described above.

  Next, after an overview of the overall processing flow in the destination guidance, the respective processing flows in the guidance mode and the other person guidance support mode will be described. FIG. 8 is a sequence diagram showing the overall processing flow in destination guidance. In FIG. 8, in order to simplify the explanation, a case where two mobile communication terminal 100 users wait is given as an example, but in actuality, three or more mobile communication terminal 100 user waits. May be performed. In this case, these mobile communication terminals 100 perform processing as described below.

  First, the user A uses the mobile communication terminal (referred to as the mobile communication terminal 100A) to set the destination guidance described above (step S101). Hereinafter, when describing each unit in the mobile communication terminal 100A, “A” is added to the end thereof. The same applies to the mobile communication terminal used by user B (referred to as mobile communication terminal 100B). In step S101, when the user A sets destination guidance, the control unit 11A transmits the short-range wireless address of the own terminal to the mail address of the user B who is the queuing partner via the network communication unit 15A. (Step S102). The control unit 11B stores the received short-range wireless address of the user A in the storage unit 12B.

  On the other hand, user B similarly uses the mobile communication terminal 100B to set the destination guidance described above (step S103). In step S103, when the user B sets the destination guidance, the control unit 11B transmits the short-range wireless address of the own terminal to the mail address of the user A who is the queuing partner via the network communication unit 15B. (Step S104). The control unit 11A stores the received short-range wireless address of the user B in the storage unit 12A. Here, since both the user A and the user B have completed the setting of the destination guidance, the control unit 11A starts the destination guidance in the guidance mode in the mobile communication terminal 100A (step S105). 11B also starts destination guidance in the guidance mode in the mobile communication terminal 100B (step S106). The user A moves toward the destination according to the guidance by the positioning unit 17A performed by the mobile communication terminal 100A in the guidance mode (step S107). On the other hand, the user B also moves toward the destination according to the guidance by the positioning unit 17B that the mobile communication terminal 100B performs in the guidance mode (step S108).

  When the distance between the current position of the mobile communication terminal 100A and the destination is less than 10 m, the control unit 11A switches from guidance by the positioning unit 17A to guidance by the electronic compass 18A according to the first method of determining the switching timing described above. (Step S109). Here, if the user A (that is, the mobile communication terminal 100A) arrives at the destination before the user B (step S110), the control unit 11A guides and assists the user who has not arrived with the operation mode. The user A is prompted to select whether to switch to the other person guidance support mode. When the user A selects to switch to the other person guidance support mode, the control unit 11A starts the operation in the other person guidance support mode (step S111). First, the control unit 11A polls the mobile communication terminal 100B at a predetermined cycle using the short-range wireless communication unit 16A (step S112). This period is, for example, 100 msec (milliseconds).

  When the short-range wireless communication unit 16B detects polling from the mobile communication terminal 100A (step S113), the control unit 11B transmits a response to the polling from the short-range wireless communication unit 16B to the mobile communication terminal 100A (step S114). . In response to this response, the control unit 11A and the control unit 11B perform pairing between the mobile communication terminal 100A and the mobile communication terminal 100B using the short-range wireless communication unit 16A and the short-range wireless communication unit 16B, respectively. (Step S115). A pass key is required for pairing with Bluetooth. Here, the control unit 11A and the control unit 11B may set a predetermined value such as “0000” in the pass key. When the pairing is completed, the control unit 11B switches from the guidance by the positioning unit 17B to the guidance by the electronic compass 18B according to the second method of determining the switching timing described above (step S116). On the other hand, the control unit 11A operating in the other person guidance support mode performs other person guidance support for the mobile communication terminal 100B using the short-range wireless communication unit 16A (step S117). On the other hand, the control unit 11B performs guidance using the electronic compass 18B while receiving support for others from the mobile communication terminal 100A. User B moves according to this guidance and arrives at the destination (step S118). When waiting for three or more users, the control unit 11A operating in the other person guidance support mode uses the short-range wireless communication unit 16A to have the user who approaches the destination next to the user B. The other person guidance support is performed for the mobile communication terminal 100.

Next, the process which the mobile communication terminal 100 performs in guidance mode is demonstrated using FIGS. 9-13.
FIG. 9 is a flowchart showing the flow of processing in the guidance mode. First, when the control unit 11 is connected to the map server device 200 using the network communication unit 15 (step S201), the map data around the destination including the location of the destination acquired from the map server device 200, and the positioning unit Based on the current position specified by 17, a map guidance image is displayed on the display unit 13 (step S 202). FIG. 10 is a diagram showing the display contents of the display unit 13 in the destination guidance by GPS. As shown in the figure, the display unit 13 displays a destination 400, a user's current position 500, and a map image. The user moves toward the destination 400 while referring to these images displayed on the display unit 13. When the control unit 11 communicates with the map server device 200 using the network communication unit 15, the image displayed on the display unit 13 is updated at a predetermined cycle as the user moves. For example, when the user who has the mobile communication terminal 100 moves 50 m to the north, the control unit 11 updates the map image with the content corresponding to the movement.

  After step S202, the control unit 11 determines whether polling from another mobile communication terminal 100 is detected using the short-range wireless communication unit 16 (step S203). When the polling is detected (step S203; YES), the control unit 11 performs pairing between the mobile communication terminal 100 of the own terminal and another mobile communication terminal 100 using the short-range wireless communication unit 16. (Step S204), the process proceeds to Step S206. On the other hand, when polling is not detected (step S203; NO), the control unit 11 determines whether or not the distance between the current position and the destination is shorter than the first threshold (here, 10 m) (step S205). ). When the distance is longer than the first threshold (step S205; NO), the control unit 11 returns the process to step S202. When the distance is shorter than the first threshold (step S205; YES), the control unit 11 performs the process. Advances to step S206.

  In step S206, the control unit 11 activates the electronic compass 18. Based on the information supplied from the electronic compass 18, the control unit 11 causes the display unit 13 to display an image imitating the azimuth compass (step S207). FIG. 11 is a diagram showing the display contents of the display unit 13 in the destination guidance by the electronic compass 18. As shown in the figure, the display unit 13 displays an image indicating the direction of east, west, south, and north, and an image of an arrow indicating the direction in which the destination exists with respect to the mobile communication terminal 100. Here, the display content of the image indicating the direction of east, west, north, and south is updated according to the detection result of the geomagnetic sensor included in the electronic compass 18. For example, when the user moves 45 degrees toward the east from a certain point, the image indicating the east, west, south, and north directions is displayed on the display unit by the control unit 11 so that the indicated directions are not different from those before the user moves. 13 is displayed. Further, in the electronic compass area, the control unit 11 includes the destination with respect to the current position based on the positional relationship between the current position and the destination specified by the positioning unit 17 and the detection result by the electronic compass 18. The direction to perform is determined at a predetermined cycle. Here, the predetermined period is, for example, 100 msec. And the control part 11 displays the image of the said arrow on the display part 13 so that the direction in the result of the said determination may be pointed out. Thereby, even if the user who owns the mobile communication terminal 100 moves, the image of the arrow is displayed on the display unit 13 so as to indicate the direction in which the destination exists with respect to the current position.

  The control unit 11 displays the display contents in the destination guidance by the electronic compass 18 on the display unit 13, and based on the map data, the current position specified by the positioning unit 17, and the position of the destination, the mobile communication terminal Whether or not 100 has arrived at the destination is determined at a predetermined cycle (step S208). Here, the predetermined period is, for example, 100 msec. In step S208, the control unit 11 specifically calculates the difference between the latitude / longitude of the destination and the latitude / longitude of the current position specified by the positioning unit 17 included in the map data acquired from the map server device 200. If it is within the predetermined range, it is determined that the mobile communication terminal 100 has arrived at the destination. If it is not within the predetermined range, it is determined that the mobile communication terminal 100 has not arrived at the destination. When it is determined that the mobile communication terminal 100 has not arrived at the destination (step S208; NO), the control unit 11 returns the process to step S207. On the other hand, when it is determined that the mobile communication terminal 100 has reached the destination (step S208; YES), the control unit 11 uses the network communication unit 15 to notify that the user of the terminal has arrived at the destination. Is transmitted to the mail address of the meeting partner stored in the mail address data 121 (step S209). FIG. 12 is a diagram showing the display content of a message notifying that the vehicle has arrived at the destination. As shown in the figure, the name of the user who has arrived at the destination is displayed on the display unit 13 of the mobile communication terminal 100 possessed by the user as the meeting partner. Upon receiving this message about arrival, the control unit 11 of the mobile communication terminal 100 adds the user included in the message to “arrived user” of the waiting data 123 in its own terminal, and sets the arrival time in “arrival date”. The date and time are added and stored in the storage unit 12.

  Next, the control unit 11 causes the display unit 13 to display an image that allows the user to select whether or not to switch the operation mode to the other person guidance support mode that supports the guidance to the destination to the other mobile communication terminals 100. It is displayed (step S210). FIG. 13 is a diagram showing an image for selecting whether to switch to the other person guidance support mode. As shown in the figure, the control unit 11 causes the display unit 13 to display an image of a button indicating an option of “Yes” and “No” together with a message “Do you want to switch to the other person guidance support mode?”. When the control unit 11 detects that the user has selected to switch to the other person guidance support mode using the operation unit 14 (step S210; YES), the control unit 11 switches the operation mode to the other person guidance support mode. Then, processing in the other person guidance support mode is performed (step S211). On the other hand, the control part 11 complete | finishes a process, when not switching to other person guidance assistance mode is selected (step S210; NO).

  Next, processing performed by the mobile communication terminal 100 in the other company guidance support mode will be described with reference to FIGS. FIG. 14 is a flowchart showing the flow of processing in the other person guidance support mode. In the other person guidance support mode, the control unit 11 performs polling at a predetermined cycle using the short-range wireless communication unit 16 (step S301). Specifically, this polling is included in the short-range wireless address data 122, and the control unit 11 sequentially sends the short-range wireless communication unit 16 to the short-range wireless address of the user set as a meeting partner. This is realized by transmitting a message asking whether communication is possible. As a result of polling, the control unit 11 receives a response from the mobile communication terminal 100 possessed by another user, and pairing is established between the mobile communication terminal 100 possessed by the other user and the mobile communication terminal 100 of the own terminal. It is determined whether or not it has been performed (step S302). As a result of polling, when there is no response from the mobile communication terminal 100 possessed by another user (step S302; NO), the control unit 11 returns the process to step S301.

  FIG. 15 is a schematic diagram for explaining polling and pairing. The black circle represents the user 300A who has arrived at the destination 400. White circles represent users 300B and 300C that have not arrived at the destination 400. A circle drawn with a broken line centering on the user 300A represents a short-range wireless communication range RC that is a range in which the mobile communication terminal 100 possessed by the user 300A can communicate using short-range wireless. As shown in the figure, the short-range wireless communication range RC has a communication range within a circle with a radius of 10 m centered on the user 300A. In the figure, after arriving at the destination 400, the user 300 </ b> A has already set the operation mode of the mobile communication terminal 100 to the other person guidance support mode using the operation unit 14.

  The control unit 11 of the mobile communication terminal 100 (referred to as the mobile communication terminal 100A) possessed by the user 300A performs the polling described above. Hereinafter, when describing each unit in the mobile communication terminal 100A, “A” is added to the end thereof. The same applies to the mobile communication terminal used by the user 300B (referred to as the mobile communication terminal 100B) and the mobile communication terminal used by the user 300C (referred to as the mobile communication terminal 100C). Here, it is assumed that the short-range wireless address data 122A stored in the storage unit 12A is as shown in FIG. Therefore, the control unit 11A performs short-range wireless communication with the mobile communication terminal 100B possessed by the user B (user 300B in FIG. 15) and the mobile communication terminal 100C possessed by the user C (user 300C in FIG. 15). Polling is performed using the unit 16A. In FIG. 15, an arrow drawn with a broken line indicates that the control unit 11 of the mobile communication terminal 100 possessed by the user at the starting point performs short-range wireless communication using the short-range wireless communication unit 16 in the direction indicated by the arrow. It represents what has been done. Of the short-range wireless communication represented by these arrows, the polling performed by the control unit 11A is P1 and P2. Polling P1 is performed toward the mobile communication terminal 100B. However, since the user 300B is not within the short-range wireless communication range RC, the control unit 11B polls using the short-range wireless communication unit 16B. P1 is never received. On the other hand, the polling P2 is performed toward the mobile communication terminal 100C, and the user 300C is within the short-range wireless communication range RC. Therefore, the control unit 11C uses the short-range wireless communication unit 16C. To receive polling P2. The control unit 11C transmits a response R to the polling P2 toward the mobile communication terminal 100A using the short-range wireless communication unit 16C. When the control unit 11A receives the response R to the polling P2 using the short-range wireless communication unit 16A, the control unit 11A performs pairing and establishes a connection by short-range wireless communication between the mobile communication terminal 100A and the mobile communication terminal 100C. .

  Returning to FIG. As a result of polling, when there is a response from the mobile communication terminal 100 of another user and pairing is performed between the mobile communication terminal 100 of the other user and the mobile communication terminal 100 of the own terminal (step S302; YES) Then, the control unit 11 of the mobile communication terminal 100 that is the own terminal transmits a connection notification to the mobile communication terminal 100 of another user using the short-range wireless communication unit 16 (step S303). In step S303, specifically, the control unit 11 of the mobile communication terminal 100 that is the own terminal has connected the short-range wireless communication to the mobile communication terminal 100 of another user that is the other party of pairing. The distance from the current position of the other user to the destination, the name of the user arriving at the destination, and the arrival date and time are transmitted as a connection notification using the short-range wireless communication unit 16.

  FIG. 16 is a diagram showing the contents of the connection notification displayed on the display unit 13 of the supported mobile communication terminal 100. As shown in the figure, the fact that the short-range wireless communication has been connected, the distance from the current position of the supported mobile communication terminal 100 to the destination, the user name arriving at the destination, and the arrival date and time, It is displayed on the display unit 13. The distance from the current position to the destination is the maximum communicable distance of the short-range wireless communication unit 16. The pairing performed in step S302 means that the mobile communication terminal 100 of the own terminal and the mobile communication terminal 100 on the connection notification receiving side are at least close to a distance at which short-range radio is possible. I mean. Therefore, the control unit 11 includes the maximum communicable distance (10 m) of the short-range wireless communication unit 16 in the connection notification as the distance from the current position of the supported mobile communication terminal 100 to the destination. Further, the control unit 11 of the mobile communication terminal 100 in the other person guidance support mode reads the arrived user and the arrival date and time from the waiting data 123 stored in the storage unit 12 of the own terminal, and arrives at the destination. The user name and arrival date / time are included in the connection notification. Such various information (especially that the short-range wireless communication is connected and the distance from the current position of the supported mobile communication terminal 100 to the destination) is provided to the mobile communication terminal 100 on the receiving side. This provides support for guidance provided by the mobile communication terminal 100.

  The control unit 11 of the mobile communication terminal 100 that has received the connection notification vibrates the vibration unit. The user who possesses the mobile communication terminal 100 that has received the connection notification can confirm that he / she is in a position close to the destination by this vibration notification. Furthermore, since the connection notification includes the distance from the current position to the destination, how close the user who owns the mobile communication terminal 100 that received the connection notification is to the destination. Can be known specifically. If the distance to the destination can be specifically known in this way, the user searches for other users who are waiting within the range of the distance, so that the destination can be easily reached. In particular, when the place where the user goes for the first time is the destination, knowing the distance to such a destination can greatly expect the effect of easily reaching the destination. Of course, it is possible to roughly predict the distance to the destination with the guidance on the map, but in this case, the calculation to replace the distance to the destination on the map with the actual distance in consideration of the map scale etc. However, in this embodiment, there is an advantage that such calculation is not necessary. In addition, since the connection notification includes the user name of the user who has arrived first and the arrival date and time, the user who sees them can check who has arrived at the destination and when. For example, when a user other than the user arrives at the destination considerably early, it is possible to take measures such as increasing the speed of walking so as to reach the destination as quickly as possible. In other words, by providing such information, it is possible to prompt a user who has not yet arrived at the destination to rush to the destination, and the waiting time is shortened for the user who has arrived at the destination first. Can be expected. On the other hand, if it is known that only one user other than himself / herself is in the middle of the destination, it is possible to take a countermeasure such as slowly moving to the destination.

  Returning again to FIG. After step S303, when the user instructs to end the other person guidance support mode using the operation unit 14 (step S304; YES), the control unit 11 ends the process. On the other hand, while the user is not instructed to end the other person guidance support mode (step S304; NO), the control unit 11 returns the process to step S301 and repeats the subsequent processes.

  FIG. 17 is a block diagram showing a functional configuration of the mobile communication terminal. The control unit 11 functions as a terminal specifying unit 111 that specifies another wireless terminal possessed by another user who waits at the destination with the user of the terminal. Further, the control unit 11 functions as a determination unit 112 that determines whether or not the user of the terminal itself has arrived at the destination using the positioning unit 17. Further, the control unit 11 functions as a plurality of guide means 113 that guides the user of the terminal to the destination by different methods using the positioning unit 17, the electronic compass 18, the network communication unit 15, the display unit 13, and the like. To do. Among these, the control unit 11 uses the network communication unit 15 to acquire the map on the display unit 13 based on the map data around the destination including the position of the destination and the current position specified by the positioning unit 17. The guidance function realized by displaying the image corresponds to the first guidance means 113a. Further, the control unit 11 causes the display unit 13 to display an image imitating the azimuth compass based on the positional relationship between the current position and the destination specified by the positioning unit 17 and the detection result by the electronic compass 18. The guidance function realized in (i) corresponds to the second guidance means 113b. Further, the control unit 11 determines, from the own terminal, the guide unit 113 that guides the user of the own terminal to the destination among the plurality of guide units 113 until it is determined that the user of the own terminal has arrived at the destination. It functions as switching means 114 that switches according to the distance to the destination. Further, the control unit 11 uses the short-range wireless communication unit 16 after it is determined that the user of the own terminal has arrived at the destination, and the other wireless terminal specified by the terminal specifying unit becomes the other wireless terminal. It functions as a support means 115 that supports the guidance to the destination to the user.

  Thus, according to the present embodiment, it is possible to provide guidance that makes it easy for each user to reach a destination where a plurality of users wait. At this time, when there is no user arriving at the destination, the mobile communication terminal 100 provides a plurality of guidance means 113 for guiding the user of the terminal to the destination by different methods, from the terminal to the destination. By switching according to the distance, each user is guided to the destination. When the user of the own terminal arrives at the destination before other users, the mobile communication terminal 100 supports guidance to the destination for the terminals possessed by the other users. Thus, the user who has not arrived at the destination can receive guidance from the mobile communication terminal 100 of the user who has arrived first to the destination in addition to the guidance by the guidance means 113 of the terminal. It becomes possible to easily reach the destination.

<Modification>
The above embodiment can be modified as follows. Note that the following modifications may be combined as appropriate.

<Modification 1>
Other person guidance support may be as follows in addition to the content of the embodiment. In the first modification, the control unit 11 of the mobile communication terminal 100 possessed by the user who has arrived at the destination first determines in advance the time required for the user to move a predetermined distance to the destination. When the threshold value is exceeded, the network communication unit 15 is used to make the timing for switching the guiding means 113 earlier than usual for the mobile communication terminal 100 of another user, that is, the user is at a point farther from the destination. When it arrives, it notifies that the guidance means 113 is switched.

  This is due to the following reasons. For example, when it takes time to move a user who has arrived at the destination earlier due to traffic jams or crowds around the destination, when an unarrived user arrives at the vicinity of the destination However, if the traffic congestion and the crowd are not yet resolved, it is difficult for the user to visually confirm the destination, and it is difficult to know which direction to proceed. Here, for example, the time required for movement in a normal time when congestion such as traffic congestion or crowding does not occur is, for example, generally about 4 km per hour on foot, so it is considered to be about 90 seconds per 100 m. Therefore, the state where congestion such as traffic jam or crowding occurs means that the time required for the movement of the user who has arrived at the destination first exceeds, for example, one and a half minutes for the last 100 m to the destination. Can be considered. Therefore, when it is considered that such a traffic jam or congestion has occurred based on the movement of the user who has arrived at the destination first until reaching the destination, the control unit 11 uses the network communication unit 15. For the mobile communication terminal 100 of the unarrived user, the timing of switching the guide means 113 from that by the positioning unit 17 to that by the electronic compass 18 is earlier than usual when there is no congestion (for example, 30 m to the destination) ). In this way, a non-arriving user who has received assistance from another person can clearly determine the direction to proceed with guidance by the electronic compass 18 even when the destination is difficult to see due to congestion in the surrounding area. Know and move to the destination without hesitation.

  In the first modification, the switching timing of the guiding means 113 includes a third timing in addition to the two types of timing in the embodiment. In the third timing, the control unit 11 uses the network communication unit 15 to send a notification indicating the distance to which the guide unit 113 should be switched from the mobile communication terminal 100 of another user who has arrived at the destination first. After receiving, it is a timing when the distance between the current position of the terminal and the destination is shorter than the distance received in the notification.

  Next, with reference to FIG. 18A, FIG. 18B, and FIG. 19, the flow of each process in the guidance mode which concerns on the modification 1, and others guidance assistance mode is demonstrated. In FIG. 18A and FIG. 18B, the processes denoted by the same reference numerals as those in FIG. 9 are the same as those in FIG. In FIG. 19, the processes denoted by the same reference numerals as those in FIG. 14 are the same as those in FIG. 18A and 18B are flowcharts showing a process flow in the guidance mode according to the first modification. In FIG. 18A, after step S202, the control unit 11 determines whether the distance between the current position of the mobile communication terminal 10 and the destination is shorter than a predetermined distance (step S202a). This predetermined distance is used when calculating the time required for the movement of the predetermined distance to the destination, and can be arbitrarily set by the user using the operation unit 14 (for example, 100 m). It is. This predetermined distance is stored in the storage unit 12 as the second threshold value. When the distance between the mobile communication terminal 10 and the destination is shorter than the second threshold (step S202a; YES), the control unit 11 starts the time measurement by the time measuring means (step S202b), and advances the process to step S202c. As described above, the longer the time required to move the predetermined distance to the destination, the higher the possibility that the destination area is congested. Therefore, it can be said that the time required for the movement of the predetermined distance to the destination represents the movement situation that is the situation when the user who has the mobile communication terminal 100 moves to the destination. That is, the control unit 11 functions as a situation specifying unit that specifies the movement status of the terminal until the user of the terminal determines that the user has arrived at the destination. On the other hand, when the distance between the current position of the mobile communication terminal 10 and the destination is longer than the predetermined distance (step S202a; NO), the control unit 11 advances the process to step S202c.

  Next, when the network communication unit 15 is used to receive a notification indicating the distance to which the guidance unit 113 should be switched from the mobile communication terminal 100 of another user (step S202c; YES), the control unit 11 It is determined whether the distance between the current position of 10 and the destination is shorter than the distance received by the notification (for example, 30 m) (step S202d). On the other hand, the control part 11 advances a process to step S203, when the said notification is not received (step S202c; NO). If it is determined in step S202d that the distance between the current position of the mobile communication terminal 10 and the destination is shorter than the distance received in the notification (step S202d; YES), the control unit 11 advances the process to step S206, and guides the means. 113 is switched from the one using GPS to the one using electronic compass 18. On the other hand, in the above determination, when the distance between the current position of the mobile communication terminal 10 and the destination is longer than the distance received in the notification (step S202d; NO), the control unit 11 advances the process to step S203. That is, when the process of step S203 is performed, that is, when the control unit 11 does not receive destination guidance support from another mobile communication terminal 100, the distance between the current position of the mobile communication terminal 100 of the own terminal and the destination However, when it becomes shorter than the 1st threshold value which is a predetermined distance, the guidance means 113 is switched. Thereafter, the control unit 11 performs processing along the flow, and when it is determined in FIG. 18B that the mobile communication terminal 100 has reached the destination (step S208; YES), the time measured is stored in the RAM, Timekeeping is terminated (step S208a). Thereafter, the control unit 11 performs processing along the flow.

  FIG. 19 is a flowchart showing a process flow in the other person guidance support mode according to the first modification. Next, the control unit 11 determines whether or not the time required to move the predetermined distance stored in the RAM in step S208a exceeds a third threshold (step S301a). The third threshold is a time (for example, 90 seconds) required for moving the predetermined distance in a normal state (here, walking at a speed of 4 km / h), and is stored in the storage unit 12 in advance. When the time required to move the predetermined distance does not exceed the third threshold value (step S301a; NO), the control unit 11 sets the normal distance (here, 10 m) as the distance to switch the guide means 113. ) Is specified (step S301b). On the other hand, when the time required to move the predetermined distance exceeds the third threshold value (step S301a; YES), the control unit 11 sets the guidance unit 113 as the distance to be switched in a normal case (that is, A longer distance (for example, 30 m) is specified (when the time is equal to or smaller than the third threshold) (step S301c). Such a longer distance than usual is stored in the storage unit 12 and can be arbitrarily set by the user using the operation unit 14. After step S301b or step S301c, the control unit 11 notifies the mobile communication terminal 100 of the user who has not yet arrived, using the network communication unit 15, the distance to which the specified guidance unit 113 should be switched (step S301d). ). By this notification, the control unit 11 functioning as a support unit instructs another mobile communication terminal 100 on the distance specified by the situation specifying unit. This notification becomes assistance for others in the second modification. At this time, the user to be notified is a user whose waiting target flag is “1” among the mail addresses included in the mail address data 121, and is not included in the arriving users in the waiting data 123. It is a user. Thereafter, the control unit 11 performs processing along the flow of FIG. The mobile communication terminal 100 on the side that has received the notification in step S301e is YES in the determination in step S202c of FIG. 18A. In this way, the control unit 11 functioning as a support unit provides support according to the movement status of the own terminal specified by the status specifying unit (here, the time required for moving a predetermined distance).

  As described above, according to the first modification, in the mobile communication terminal 100 of a user who has not arrived, for example, when congestion occurs near the destination, an earlier point in time than when congestion does not occur Thus, the guide means 113 is switched to one using the electronic compass 18. As a result, a user who has not arrived can move to the destination without hesitation according to the direction indicated by the image of the compass displayed on the display unit 13, even if there is congestion in the vicinity of the destination.

<Modification 2>
The other person guidance support performed by the mobile communication terminal 100 may include the following. For example, an event that obstructs traffic such as construction has occurred on a certain travel route through which a user who has arrived at the destination first passes. In such a case, it is more convenient for the user that the user who has not arrived is informed that it is better to go to the destination by a different travel route. Therefore, if the time required for the terminal to travel a predetermined distance through a certain travel route to the destination exceeds a predetermined threshold, the mobile communication terminal 100 uses the travel route. The information indicating that there is no data may be generated and transmitted to another mobile communication terminal 100.

  The flow of each process in the guidance mode and the other person guidance support mode according to the modification 2 is only partially different from FIGS. 18A, 18B, and 19, and different points will be described. In the guidance mode, when the distance between the current position of the mobile communication terminal 10 and the destination is shorter than a predetermined distance (step S202a; YES), the control unit 11 starts measuring time (step S202b). A process of storing the acquired transition of the current position of the mobile communication terminal 100 in the RAM is started, and the process proceeds to step S202c. The transition of the current position stored in the RAM becomes a movement route through which the mobile communication terminal 100 of the own terminal passes. If the control unit 11 determines that the mobile communication terminal 100 has reached the destination (step S208; YES), the control unit 11 stores the time measured by the time measuring function in the RAM and terminates the time counting (step S208a). The process of storing the transition of the current position of the mobile communication terminal 100 in the RAM is stopped.

  In addition, in the other person guidance support mode, when the time required to move the predetermined distance exceeds the second threshold (step S301b; YES), the control unit 11 should switch the guidance means 113. When the distance longer than usual is specified (step S301d), the network communication unit 15 uses the network communication unit 15 to store information indicating the travel route through which the terminal is stored stored in the RAM and to exclude the travel route. Notification is made to the mobile communication terminal 100 of the arriving user. This notification is information for another mobile communication terminal 100 to determine a travel route to the destination.

  FIG. 20 is a diagram showing the display content of the display unit 13 when a certain travel route is excluded in the destination guidance by GPS. As shown in the figure, the display unit 13 displays a destination 400, a user's current position 500, and a map image. Arrows indicated by broken lines represent excluded travel paths. An arrow indicated by a solid line is a movement route presented to the mobile communication terminal 100 instead of the excluded movement route. Upon receiving the above notification, the control unit 11 of the mobile communication terminal 100 stores information indicating the excluded movement route in the RAM, and displays the movement route as an arrow indicated by a broken line on the map image. To display. Then, the control unit 11 removes the excluded travel route from the plurality of route groups to the destination, and sets the route having the shortest travel distance from the remaining travel routes as the travel route until the user of the terminal reaches the destination. The movement path is determined and displayed on the display unit 13 as an arrow indicated by a solid line. As shown in the figure, the movement route indicated by the solid line is different from the movement route indicated by the broken line.

  As described above, the control unit 11 functioning as the support unit 115 allows other mobile communication terminals 100 to move to the destination based on the time required for the terminal to move to the destination and the movement route to the destination. Information for determining a route (exclusion of a specific moving route here) is generated, and the generated information is transmitted to the other mobile communication terminal 100.

  As described above, according to the second modification, when a travel route through which a user who has arrived at the destination first takes time, the travel route is excluded from the unarrived user. Notification is made. Thereby, in the mobile communication terminal 100, the guide means 113 that guides the user of the own terminal to the destination is based on the information transmitted from the other mobile communication terminal 100, so that the user of the own terminal moves to the destination. The travel route is determined, and the travel route is guided. As a result, a user who has not arrived travels to the destination while avoiding a travel route that requires time, and therefore travels to the destination without unnecessary time.

<Modification 3>
A method of selecting a meeting partner when setting for destination guidance is performed by the user using the operation unit 14 to select from a list box or a check box on the setting screen displayed on the display unit 13, It is good also as such. In the third modification, the storage unit 12 stores a telephone book in which names of acquaintances and friends are associated with telephone numbers, mail addresses, and the like. A button for referring to the telephone book is displayed on the setting screen displayed on the display unit 13 when setting for destination guidance is performed. When the user presses the button using the operation unit 14, an image representing the contents of the phone book is displayed on the display unit 13. When the user selects a specific user from the image representing the contents of the phone book, the control unit 11 sets the selected user as a meeting partner and refers to the mail address data 121 to check the mail of the user. The short-range wireless address of the terminal is sent to the address. Even if it does in this way, there can exist an effect similar to embodiment.

<Modification 4>
For example, there is a case where a user who has arrived at the destination first moves to a place away from the initially set destination and waits for another user because the vicinity of the destination is congested. In this case, if there is no communication, users who have not arrived will move toward the initially set destination, and will need to search each other even if they arrive at the destination. In this way, when a user who has arrived at the destination first waits at a place away from the initially set destination, the user may be notified of the away place by telephone or e-mail. Although it is possible, this communication may be troublesome when there are a plurality of meeting partners. Therefore, in such a case, when the control unit 11 of the mobile communication terminal 100 of the user who has arrived first is more than a predetermined distance from the destination, information indicating that the meeting place has been moved is generated. The information may be notified to the mobile communication terminal 100 of the arriving user. This also helps others.

  The flow of each process in the guidance mode and the other person guidance support mode according to the modified example 4 is only partially different from those in FIGS. 18A, 18B, and 19, and different points will be described. First, in the other person guidance support mode, the control unit 11 of the mobile communication terminal 100 possessed by the user who has arrived at the destination first is in a predetermined cycle between step S301e and step S301 in FIG. It is determined whether the terminal is more than a predetermined distance from the destination. This predetermined distance is stored in the storage unit 12 and can be changed by the user using the operation unit 14. In addition, the predetermined period here is, for example, 1 second. In the above determination, when the distance between the position of the destination and the current position is equal to or greater than a predetermined distance, the control unit 11 sets the current position as the destination and newly uses the network communication unit 15. The position information of the set destination (that is, the current position) is transmitted to the mobile communication terminal 100 of the user who has not arrived. On the other hand, the control unit 11 of the mobile communication terminal 100 in the guidance mode possessed by the user who has not arrived determines whether or not a notification that the destination has been changed has been received before step S202 in FIG. 18A. If the notification is received as a result of the determination, the control unit 11 updates the setting of the destination in the own terminal based on the position information included in the notification. Further, even before step S207 in FIG. 18B, the control unit 11 determines whether or not a notification that the destination has been changed has been received, and updates the destination setting based on the determination result.

  In this way, when the user who has arrived earlier is crowded in the vicinity of the destination, when moving to a place away from the initially set destination and waiting for another user, the new position is changed. By notifying the user who has not arrived as the destination, the meeting can be performed smoothly. Further, at this time, the user does not need to perform an operation using the operation unit 14 himself, so that the user does not feel bothered.

<Modification 5>
Further, the plurality of guide means 113 that guide the user of the terminal to the destination by different methods may fulfill the function of cooperating with a server device (not shown) connected to the network NW. For example, when a plurality of server devices having a positioning function by GPS are connected to the network NW, the plurality of server devices cooperate based on the current position specified by the positioning unit 17 included in the mobile communication terminal 100. By performing positioning, the current position is specified more precisely than when the positioning unit 17 performs positioning alone, and the specified result is transmitted to the mobile communication terminal 100. The control unit 11 causes the display unit 13 to display a map image based on the received current position and map data. In this way, since the current position displayed on the display unit 13 is more accurate, the user can more accurately confirm the position where the user is with respect to the destination.

<Modification 6>
In addition to the communication system using the mobile communication terminal 100, the present invention can be understood as a guide method using the mobile communication terminal 100 and a program for causing a computer to implement a guide function. Such a program may be provided in the form of a recording medium such as an optical disk storing the program, or may be provided in the form of being downloaded to a computer via the Internet or the like and installed and used.
