2. Description of the Related Art Conventionally, a GPS (Global Positioning System) has been used as a mobile communication terminal capable of displaying its current position.
Stem) A mobile terminal such as a mobile phone having a position detecting means such as a receiver, a vehicle-mounted navigation device having a communication means, and the like are known.

A mobile communication terminal of this type generally has a G
It is equipped with a map display function that displays the position of the user who is received and positioned by the PS receiver together with its surrounding map, and displays a map of the area surrounding the area specified by the user. The position can be confirmed on the map.

Further, in particular, in a mobile communication terminal capable of searching for a route to a destination designated by the user, the user can display his / her own current position and destination on a map, and also an appropriate route to the destination. Since the user can confirm the route to the destination, the user can arrive at the destination without getting lost.

[0005]

However, in the mobile communication terminals mentioned in the above-mentioned prior art, there is only a function of displaying the position of the user himself or the route to the destination on the peripheral map. However, when trying to meet the other party who communicates with his / her mobile communication terminal, it is difficult to grasp the other party's position by using the map display function.

That is, in the conventional mobile communication terminal, the user can only confirm the position of himself / herself. Therefore, when he / she wants to know the position of the communication partner, he / she can find out the position of the partner by telephone or the like. I had to. However, in this case, of course, since the other party's position must be grasped from the content expressed by the other party, the user does not know the area name of the place where the other party is, or the other party is present. When there was no facility in place that could be used as a landmark for accurately expressing that place, it was sometimes difficult to find out the person's position from the other party.

Further, even if the user finds out the position of the other party, if the place is a place that the user does not know, the user searches for the position on the map using the map display function of the mobile communication terminal. I needed to check. In this case, of course, a person who is not familiar with the geography of the area will search for the position of the other party on the map, so it took a lot of effort to find the position on the map.

That is, although the conventional mobile communication terminal has a map display function, it cannot be effectively utilized for grasping the position of the other party. Therefore, even if the user tries to meet the other party, it may take a great deal of effort to actually meet the person.

Then, the MPU 31 at S320,
It is determined whether the user has selected one of the above access methods, and if the access method is selected (S3
If Yes (No in S20), the process proceeds to S330, and if not selected (No in S320), it is determined in S325 whether or not a command to interrupt this process is input from the user via the operation unit 17. If the suspension instruction has been issued (Yes in S325), the navigation processing is ended, and if the suspension instruction has not been issued (N in S325, N).
o) until the access means is selected (Yes in S320)
s) Wait.

When the processing shifts from S320 to S330, the MPU 31 determines whether or not the access means uses transportation, that is, "railroad &bus" on the selection screen.
If it is selected, and if the transportation is to be used, in S400, a transportation navigation process (described later) is executed.

On the other hand, when it is determined in S330 that the transportation is not used, that is, when "automobile" or "walking" is selected on the selection screen, the MPU 31 executes the process in S3.
In step S120 of the position confirmation processing, it is determined whether or not the position detecting unit 13 can detect the self-position,
If there is own position data (Yes in S340), the process proceeds to S350, and if there is no position data (N in S340, N
o), displaying a message on the screen to the effect that only access means using transportation can be selected,
Return to 320.

It should be noted that the difference between the case of using the transportation system and the case of not using the transportation system is that the user's position data is required or not. Even if the information cannot be obtained from the position detection unit 13, it is necessary to allow the user to manually input the departure station and the stop of the transportation so that the user can display the route to the destination thereafter. This is because it is more convenient. On the other hand, in "automobile" and "walk", if the user's position is not correctly grasped even if the user inputs the departure place, the route from the user's current position (self position) to the destination is displayed. Since it is not possible to guide the user to a sufficient destination, the user does not dare to request the input of the departure place, and the processes after S350 cannot be performed.

Subsequently, when the processing proceeds to S350, M
The PU 31 determines whether or not the position data has been acquired from the partner terminal. That is, if the position data of the other party is acquired in S200 of the position confirmation processing, it is determined that there is the position data of the other party (Yes in S350), S36.
At 0, the position of the other party is set as the destination.

On the other hand, if there is no position data of the other party, M
The PU 31 shifts to the point input mode in S355,
Ask the user to enter the destination. Note that this point input mode is similar to the mode in which the user sets the destination with a well-known car navigation device. For example, the destination fixed telephone number, the destination address, the postal code, etc. Allows the user to input, or allows the user to select a destination from a list of pre-registered buildings such as specific public facilities and transportation facilities (stations, etc.).

Then, in S355, when the user is prompted to input the destination, the MPU 31 sets the input point to
In S360, the destination is set. After this, MPU31
In step S370, a route setting process for a road is performed to search for a route using the Dijkstra method or a method similar to the known car navigation device, and from the current position of the mobile phone 1 (that is, the self position), A route along the road to the destination set in S360 is set.

When the access means "walking" is selected on the selection screen, the route is searched while ignoring the traffic rules such as one-way traffic that apply only to automobiles. Further, when calculating the time required to reach the destination as in the case of the conventional car navigation system, the user naturally calculates the average time required when walking to the destination at an average speed.

In addition, if a park or a passage map (link connection information regarding passages) in the building is stored in the data storage unit 15 as map data, the park or the public may be stored as needed. It is possible to search for routes that pass through the facility. When the route is set in this way, M
In S380, the PU 31 displays a map around its own position on the display unit 19 based on the map data stored in the data storage unit 15, and displays the route set on this map in color along the road. To do. At this time, the self position and the current position of the other party are displayed as marks on the map. At the same time, the MPU 31 estimates the arrival time at the destination by adding the calculated average required time to the current time, and displays this on the display unit 19 in characters (not shown).

Thereafter, the MPU 31 displays a message or the like asking the user whether or not to register the set route in S390, stands by, and indicates that the user will register the set route via the operation unit 17. Is input (S39
0, Yes), in S395 RAM in MPU31,
The route and the expected arrival time at the destination are stored.

The setting route is stored in this way so that the user can display and confirm the stored route anytime later. That is, the mobile phone 1 of the present embodiment is configured such that when the map within the range in which the stored route can be displayed is displayed, the set route is always displayed on the map.
In S134 of the position display processing described above, when displaying the peripheral map, the 31 determines whether the stored route can be displayed, and if the route can be displayed, displays the route overlaid on the map.

Next, a description will be given of the transportation navigation processing executed by the MPU 31 in S400 when it is determined in S330 that "railroad &bus" is selected as the access means. FIG. 6 is a flowchart showing this navigation processing for transportation.

As shown in FIG. 6, the MPU 31 first sets S
At 410, it is determined whether or not the own position data is present, that is, whether or not the own position is detected at S120. If there is the own position data, the process proceeds to S420 to set the own position as a route. Set as the starting point (starting point). On the other hand, if there is no own position data, the process proceeds to the transportation mode input mode in S415.

In this transportation mode input mode, the user can select or directly input the boarding station (stop) of the desired transportation system. For example, the MPU 31 is stored in the data storage unit 15 in advance. Railroad and bus company names ("JR", "Nagoya City Bus") based on transportation data
Etc.) on the screen, let the user select a railway (bus) company, and then list the route names (Tokaido Main Line, Chuo Line, etc.) of the selected company and use it for the user. Select a route, display a list of stations (stops) on the selected route, and select a boarding station (stop). For example, if the user directly inputs the boarding station name, MPU31
Searches the applicable station from the transportation data, displays the search result, asks the user to set it as the boarding station, and then ends this input mode, and returns to S420.
In, set the boarding station as the departure place.

When the departure place is set in this way, the MPU
31 determines whether or not the location data of the other party is present in S430, that is, whether or not the location data is acquired from the other party terminal in the previous process (S200), and the location of the other party is determined. If there is data (Yes in S430)
s), in S440, the user is asked whether to set the destination position as the destination, and when the user inputs a command to set the destination position as the destination (Yes in S440), S45
At 0, the destination position is set as the destination.

On the other hand, the MPU 31 determines in S430 that there is no other party's position data (No in S430), or that the user has input a command not to set the other party's position as the destination. When judged (No in S440),
In step S445, the mode is changed to the point input mode (described in step S355 described above), and the user is made to specify the destination. Incidentally, in the point input mode, the user can shift to the transportation input mode so that the user can set a station or a stop as a destination.

Then, in this point input mode, when the destination is specified by the user, the MPU 31 moves to S45.
At 0, the designated point is set as the destination.
After that, the MPU 31 executes the transportation route setting process (FIG. 7) in S460 to set the route from the set starting point to the destination. FIG. 7 is a flowchart showing a route setting process for transportation facilities.

In this process, the MPU 31 firstly returns to S46.
In 1, it is determined whether the set departure place is a station (or a stop) and it is determined that it is not a station (or a stop) (No in S461), and in S462, a station within a predetermined range from the departure place ( Or MPU31.
In S463, based on the search result, each route to the searched station (or stop) is searched, and the distance from the departure place to each station, the required time (walking), etc. are calculated. On the other hand, the departure place is the station, that is, Yes in S461.
If it is determined that the MPU31, S462 and S4 above.
The process proceeds to S465 without performing the process of 63.

Next, the MPU 31 determines in S465 whether the set destination is a station (or a stop), and if it is not the station (or a stop) (N in S465).
o), after finding a station (or a stop) within a predetermined range from the destination (S466), a travel distance and a required time are calculated by searching a route to each of the searched stations (or stops). (S467), the process proceeds to S468.
On the other hand, if it is determined Yes in S465, the process proceeds to S468 without performing the above process.

In S468, the MPU 31 determines in S461.
By connecting each line from the station (or stop) within the predetermined range based on the departure point searched in the steps up to S467 to the station (or stop) within the predetermined range based on the destination, Search for transportation routes that can move to the destination. At this time, the detour route that the user does not think to be selected at all is excluded from the transportation route that can move to the destination.

After that, in S470, the MPU 31 asks the user whether or not he / she wants to use the transportation immediately, and if he / she wants to use it (Yes in S470), the user trains at the station or stop searched in S471. Calculate the time when you can board the bus. In other words, if the departure place is not a station (or stop), the user will be at the set departure place, so the MPU 31 will make the user arrive at the station (stop) and enter the train (bus). Time when you can board (boarding time)
Is calculated from the current time and the time required to move to the boarding station (or stop), the process proceeds to S473, and the train that departs earliest from the boarding station (or stop) thereafter at that boardable time ( Bus) is searched for in each of the routes searched in S468.

On the other hand, when it is determined in S470 that the user does not use the transportation facility immediately, the MPU 31 determines that
In S472, the mode shifts to the time input mode, and the user is prompted to input the boarding time. After that, in S473, the input boarding time is set as the boarding available time, and a train (bus) departing from that time is searched.

When the train (bus) finishes searching, MPU3
In step S474, the result 1 is collected and a determination database (DB) is created. Note that FIG. 8 is an explanatory diagram showing this determination database. After this, the MPU 31 sets S47.
In step 5, based on the determination database, the most suitable transportation candidates are displayed in the order of priority. That is, MPU31
Is the distance from the place of departure to the boarding station (or stop), the distance from the getting-off station (or stop) to the destination, the departure time of the train departing at the boarding station (or stop) that is available, and the arrival at the getting-off station When evaluating each candidate with parameters such as the time to go, the time required from the boarding station (or stop) to the disembarking station (or stop), the fare, etc. and determining the priority order to display to the user, the user Each parameter is weighted and evaluated so that the preferred transportation system is preferentially displayed.

For example, taking the transportation shown in FIG. 8 as an example, when the user preferentially displays the transportation that can move to the disembarkation station in a short time, the MPU 31 causes the display unit 19 to display the searched transportation. The institutions are displayed in order of candidate 1, candidate 2, candidate 3, candidate 4. On the other hand, if the user wants to use a transportation system with a low fare, the transportation systems are displayed in the order of candidate 1, candidate 2, candidate 4, candidate 3, and the candidates are displayed in order of the transportation system with the lowest fare. indicate. In addition, in the mobile phone 1 of the present embodiment, the total distance from the departure place to the boarding station and from the getting off station to the destination is in the order of shortest, that is, candidate 4,
It is possible to display transportation means in order of candidate 3, candidate 1, and candidate 2, and it is possible to set an optimal transportation means for a person who does not like to walk for a long time.

At this time, various information as shown in FIG. 8 may be displayed all at once on the screen, but considering that the display screen of the mobile phone is relatively small, Information such as the line name, boarding station, alighting station, and departure time is displayed on the screen, and other various information can be displayed as needed (for example, in response to a user's command). It is preferable to construct the telephone 1.

Then, when it is judged in S476 that the transportation means displayed in this way is selected (Yes in S476).
s), in S477, the MPU 31 sets the route from the departure place to the destination when using the selected transportation as the set route. That is, the MPU 31 determines S46.
The route along the road from the point of departure to the boarding station searched in 3 and the boarding route of the train (bus) from the boarding station (stop) to the exit station (stop) selected in S468;
This processing is ended with the route connecting the route along the road from the exit station (stop) searched in 67 to the destination set as the set route, and the process proceeds to S480 of the navigation process for transportation shown in FIG. Then, the mode is changed to the route display mode and the set route is displayed. 9. FIG. 9 is an explanatory diagram showing the configuration of each screen displayed in the route display mode of S480.

In this route display mode, the MPU 31
According to the user's command, the route from the place of departure (marked with ● in Fig. 9) to the boarding station ("Nagoya station" in Fig. 9) is shown (thick line in Fig. 9 (a)) Map screen (Fig. 9 (a)),
A map screen (Fig. 9 (b)) showing the route (thick line shown in Fig. 9 (b)) from the exit station ("Kanayama Station" in Fig. 9) to the destination (marked with ▲ in Fig. 9). , The character display screen (FIG. 9 (c)) showing various kinds of information on the transportation facility selected in step S476 is switched and displayed on the screen. You can check all routes from the ground to the destination.

In this embodiment, the transportation included in the route from the place of departure to the destination is the route name (the characters "JR Tokaido Main Line" shown in FIG. 9) as shown in FIG. 9 (c). , Boarding station (character "Nagoya Station" shown in Fig. 9), departure time of the train (character "Departure 10:15" shown in Fig. 9), alighting station (character "Kanayama Station" shown in Fig. 9), arrival of train Time (character 10:18 in FIG. 9), standard boarding time (see FIG. 9)
Information such as the characters "standard 3 minutes" shown in FIG. In addition, when there is a transfer such as a train, the above information from the boarding station (nearest station of the departure place) to the transfer station is displayed on the screen, and the transfer station to the exit station (the nearest station of the destination). ) To display each of the above information. That is, the above-mentioned information is displayed for each train (bus) to be boarded.

When the route display mode is terminated by the user's instruction, the MPU 31 next asks at S490 whether or not to register these pieces of information. If processing is to be completed and registration is to be performed (Yes in S490), S4
After the information of the set route is stored in the RAM at 95, this processing is ended. Note that the information is stored here so that the user can call this route and redisplay the screen of FIG. 9 later, and in the mobile phone 1, the user operates the operation unit 17 to operate. When a route confirmation command is input, a redisplay function is provided on the screen of the display unit 19 to display the route again with the screen configuration of FIG.

The navigation processing has been described above. Since the MPU executes such a program,
By using the mobile phone 1 of the present embodiment, the user can set the destination position to the destination, and by using the navigation function,
You can move to the place of the other person without hesitation and easily meet the other person.

Further, the mobile phone 1 of this embodiment is similar to the above-mentioned destination terminal (mobile phone 1 ') in that the position data is transmitted from the destination terminal (mobile phone 1'). The data regarding the self-position acquired from the detection unit 13 can be transmitted to the partner terminal. Here, FIG. 10 is a flowchart showing a position data transmission process executed by the MPU 31 when a transmission request for position data is sent from the partner terminal.

When this position data transmission process is executed,
First, in S510, the MPU 31 confirms whether or not the other party who may transmit the position data. At this time, mobile phone 1
May ask the user whether or not to send it, or may check whether or not the user is a registered person by checking the registration list as if the user may send in advance.

And here, the position data is not transmitted,
That is, if it is determined that the position data transmission request is not satisfied (No in S510), the present process is terminated without performing the subsequent processes (S520-). On the other hand, if the MPU 31 responds to the position data transmission request, that is, if Yes in step S510, then in step S520, the position detection unit 13 is requested to detect the current position. And S530
Then, the position detecting unit 13 confirms whether or not the current position can be detected. If the current position is detected, the position data is transmitted to the partner terminal (S540), and then the present process is ended. On the other hand, when the position detection unit 13 cannot detect the current position even after the lapse of a predetermined time (S550), this processing ends. It should be noted that the connection with the destination terminal may be ended at the same time when this processing is ended.

Further, the mobile phone 1 of the present embodiment, in addition to transmitting its own position information to the other party, the other party, or the route information to reach the arbitrarily set destination It can be sent to the terminal. That is,
The mobile phone 1 performs the R of the MPU 31 in S395 of the navigation processing and S495 of the navigation processing for transportation.
The configuration is such that the information on the set route stored in the AM can be transmitted to the partner terminal, and the information on the set route transmitted from the partner terminal can be received and displayed. Here, FIG.
1 (a) is a flowchart showing a route transmission process, FIG.
1 (b) is a flowchart showing the route receiving process.

First, in the MPU 31, the user operates the operation unit 17
When a route transmission command is input from the operation unit 17 by operating, the route transmission process is executed, and in S610,
Route transmission mode that transmits both set route and arrival time,
It is determined which of the arrival time transmission modes for transmitting only the arrival time is selected, and if it is the route transmission mode, the set route and the arrival time stored in the RAM are read out at S620, and at S630. , And sends it to the destination terminal.

On the other hand, when the arrival time transmission mode is selected, the arrival time is read from the RAM in S640, and this information is transmitted to the destination terminal in S650. As a transmission method, the mobile phone 1 may directly connect to the destination terminal via the telephone line network and then transmit the information on the set route, or the information on the set route may be sent to an external service center. Alternatively, the information of the set route may be transmitted to the destination terminal via the service center.

Next, the destination terminal (mobile phone 1 ') having the same structure as the mobile phone 1 receives route information in S630 and S650.
When the arrival time information is sent, MP of the mobile phone 1
The route reception process executed by U31 will be described. Upon receiving these pieces of information, the MPU 31 first determines in step S710 whether the received information is the route information (that is, the information transmitted in step S630). If the information is the route information, in step S720. The information of the set route is displayed on the display unit 19 in the same manner as the display method shown in FIG. 9, and the information of the arrival time sent together with the information of the set route is displayed on the display unit 19. To do. That is, when the user moves on foot or by car, the MPU 31 displays the route along the road on the display unit 19, and when the user uses the transportation, the information on the transportation is displayed on the display unit 19. Display,
In addition to this, the arrival time is displayed in characters.

On the other hand, when it is determined in S710 that only the arrival time information has been received, the arrival time is displayed on the display unit 19 in S730. That is, for example, MPU31
Displays the message of arrival time such as “Mr. XX will arrive at about XX hour” on the display unit 19 in characters.

When these steps are completed,
In S740, the MPU 31 inquires of the user whether to register the received information, and if a registration command is input from the user, the MPU 31 stores the received information in its own RAM in S745. , The process ends. Also,
When the registration command is not input in S740, the process is finished as it is.

Therefore, according to the mobile phone 1 of this embodiment, the user can show the route to the other party to the other party without explaining to the other party in words, and at the same time, arrive at the other party. Can inform you. As a result of this,
Based on the received route, the other party can grasp the moving method of the transmitting person, and if he / she moves along the transmitted route, without passing through the transmitting user, You can meet on the way. In addition, once the arrival time is confirmed, it is not frustrating because the person who has been waiting does not come easily, and the stress of waiting as in the past is not felt.

Although the embodiment of the present invention has been described above, the self-position acquisition means of the present invention performs the process of the MPU 31 acquiring the position information from the position detecting unit 13 of the mobile phone 1 (S).
120 to S125), and the communication destination position acquisition means is
The MPU 31 of the mobile phone 1 performs steps S150 to S200.
This is equivalent to the operation of performing the processes up to and acquiring the position data of the other party via the transmission / reception unit 11. The display means of the present invention is the display unit 1 of the mobile phone 1 in the present embodiment.
The display control means of the present invention corresponds to each of the above-described processes (position display process and navigation process) executed by the MPU 31.

Particularly, the operation for the display control means to display the self position information and the communication destination position information on the display means is realized by the position display processing executed by the MPU 31 in this embodiment. The route setting means of the present invention is M
It is realized by the navigation process executed by PU31,
The operation for the route setting means to search for and set a route using transportation is realized by the transportation navigation processing of the present embodiment.

In addition to this, the position information transmitting means of the present invention is M

It is realized by transmitting the position data via.
Further, the route transmitting means and the arrival time transmitting means of the present invention are
This operation corresponds to the route transmission process executed by the MPU 31, and the operation of the communication destination position acquisition means of the present invention to acquire the received route is realized by the route reception process executed by the MPU 31.

Further, the mobile communication terminal of the present invention mainly acquires the position of the terminal from the external communication terminal owned by the other party so that the other party can easily meet with the communication partner, and displays the position indicating this position. Since the information is displayed to the user, the present invention is not limited to the above-mentioned embodiment as long as it does not violate this gist, and various modes can be adopted.

For example, in this embodiment, the map data is stored in the data storage unit 15 of the mobile phone 1, but this is stored in an external center and the mobile phone 1 uses its own communication function. Then, the necessary information may be acquired from the center. That is, for example, by causing the center to execute the position display processing and the navigation processing,
The mobile phone 1 may be configured to receive display control from the center, display a message to the user, a map, and the like, and directly transmit a command input by the user through the operation unit to the center. . In this way, the data storage unit 15 is not required in the mobile phone 1, so that the mobile phone having the above function can be provided to the user at low cost. In this case, S39 of the navigation processing
5 and S495 of the transportation navigation processing executed during this navigation processing, the set route is stored in the mobile phone 1. In this way, when the user reconfirms the route thereafter, there is no need to acquire the data necessary for displaying the route from the center, which is convenient.
