Description

The present invention relates to a position measuring device and a position information service system .

An apparatus for periodically measuring the current position is, for example, a car navigation system. The car navigation system performs route guidance by periodically measuring the current position. In mobile terminal devices such as mobile phones, a service that uses GPS (Global Positioning System) etc. to periodically measure the current position of the mobile terminal device and use the obtained current position Is provided.
However, power is consumed by positioning the current position, and the usable time of the mobile terminal device is shortened. When performing regular positioning, since power is consumed regularly, the usable time of the mobile terminal device is particularly shortened.
On the other hand, in Patent Document 1, it is determined that the position detection device is in a stationary state when it is detected that the position detection device continues to be in the same base station, and power consumption is reduced by increasing the positioning interval. A method has been proposed. This position detection device shortens the positioning interval when it moves into the area of another base station.
Further, in the method proposed in Patent Document 2, the mobile body position reporting device includes a state input means, and the work state of whether the positioning target (carrying person of the mobile body position reporting device) is working or moving is determined. The positioning subject himself / herself inputs the information to the mobile body position reporting device using the state input means. The moving body position reporting device determines that frequent positioning is unnecessary when the work is input, and lengthens the positioning interval to reduce power consumption.

JP 2006-153695 A JP 2004-48473 A

As described above, when the current position is periodically measured by GPS or the like, power consumption increases depending on the frequency. In particular, in a portable terminal device having a battery capacity that is not so large, the increase in power consumption significantly reduces the usable time of the portable terminal device. Further, when the position information is transmitted to the server every time positioning is performed, the number of times the position information is transmitted increases as the positioning frequency increases, so that power consumption further increases.
In the method of Patent Document 1, when the position detection device moves within the same base station, the positioning interval becomes long despite the movement, and the position detection device may not perform positioning when positioning is required. is there. Further, when the position detection apparatus moves between areas of the base station, power consumption is not reduced. In particular, when the position detection device is in the vicinity of the area boundary of the base station, the base stations in the area are frequently switched, and the power consumption may not be reduced.
Further, in the method of Patent Document 2, the positioning interval is switched at the timing when the person to be measured inputs the work state. Therefore, if there is an operation error or forgetting operation, the power consumption is not reduced or positioning is required when positioning is required. The reporting device may not perform positioning.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a position measurement device that can reduce power consumption due to positioning without being based on the area of a base station or the timing of user operation. There is.

In the figure, a location information service system 1 includes a GPS satellite 2, a mobile terminal device 3, a base station device 4, and an information server device 5.
The GPS satellite 2 transmits a signal for the mobile terminal device 3 to perform positioning. The mobile terminal device 3 receives a signal from the GPS satellite 2 and periodically measures the current position. Hereinafter, the measurement of the current position is also referred to as positioning of the current position or simply positioning. The mobile terminal device 3 transmits a location-related service information request signal including information on the measured current location (hereinafter also referred to as location information) to the information server device 5 via the base station device 4.

  The information server device 5 reads the location information from the location related service information request signal transmitted by the mobile terminal device 3. The information server device 5 generates location-related service information based on the read location information, and transmits the location-related service information to the mobile terminal device 3 via the base station device 4. The location-related service information here is information related to the current position of the mobile terminal device 3, for example, information on a park or store near or in the moving direction of the mobile terminal device 3, or the mobile terminal device 3. Train operation information in the vicinity of the current position or in the moving direction. The user of the mobile terminal device 3 can determine and execute the next action based on the location-related service information. The location related service information is provided as a push type service. That is, since the mobile terminal device 3 periodically transmits a location-related service information request signal and receives location-related service information, the user can acquire location-related service information without performing any special operation.

FIG. 2 is a configuration diagram illustrating a schematic configuration of the mobile terminal device 3.
In the figure, the mobile terminal device 3 includes a route search unit 101, a position related information service unit 102, a positioning unit 14, a transmission unit 16, a receiving unit 17, and a positioning interval measurement timer unit (hereinafter also referred to as a positioning timer unit). 18, an operation unit 31, and a display unit 32. The route search unit 101 includes a destination setting unit 10, a destination arrival scheduled time setting unit 11, and a movement route determination unit 12. The location related information service unit 102 includes a waiting time timer unit 15, a positioning control unit 13, a waiting position storage unit 21, a movement route information storage unit 22, a positioning control mode storage unit 23, and a destination storage unit 24. .
The operation unit 31 includes key buttons such as 0 to 9 numeric keys, up / down / left / right direction keys, and an enter key. When the key button is pressed, the operation unit 31 inputs a signal corresponding to the pressed key button to the destination setting unit 10, the destination arrival scheduled time setting unit 11, and the positioning control unit 13.
In the route search unit 101, the destination setting unit 10 sets a route search destination based on a signal from the operation unit 31. The destination arrival scheduled time setting unit 11 sets the destination arrival scheduled time in the route search based on the signal from the operation unit 31. The movement route determination unit 12 performs a route search based on the destination set by the destination setting unit 10, the destination arrival scheduled time set by the destination arrival scheduled time setting unit 11, and the position information measured by the positioning unit 14. To determine the travel route. The movement route determination unit 12 inputs information on the determined movement route to the display unit 32. In addition, the travel route determination unit 12 writes the determined travel route information in the travel route information storage unit 22. The display unit 32 includes a liquid crystal panel, and displays the travel route determined by the travel route determination unit 12 according to the travel route information input from the travel route determination unit 12.
Thus, the route search unit 101 is based on the destination set by the destination setting unit 10, the destination arrival scheduled time set by the destination arrival time setting unit 11, and the current position measured by the positioning unit 14. A route search is performed by the movement route determination unit 12, a movement route that arrives at the destination by one or more movements is determined, and information on the movement route is generated.

The travel route information storage unit 22 stores the travel route information generated by the travel route determination unit 12. FIG. 3 is a data configuration diagram showing a data configuration of information on a movement route. The travel route information storage unit 22 stores travel route information as tabular data. The travel route information storage unit 22 generates travel route information composed of one or a plurality of stages, and each row of data in the travel route information corresponds to one stage of the travel route information. Hereinafter, the information for one step in the information on the movement route is also referred to as one-step movement information. For movement using a vehicle such as a train or a bus, the movement route determination unit 12 sets the movement performed from getting on the vehicle to getting off the vehicle as one stage of the movement route. In addition, for the movement by walking, the movement path determination unit 12 sets the movement from the start of the walking movement to the position where the next movement using the vehicle is started as one stage of the movement path. If there is no movement using the vehicle next to the walking movement, the movement path determination unit 12 sets the stage from the start of the walking movement to the arrival at the destination as one stage of the movement path.
In the figure, the information on the movement route includes a transportation means name, a movement start time, a movement start position name, a movement start position, an arrival time, and an arrival position name. The name of the moving means is the name of the moving means that moves, for example, the train route name and the destination of the train. The movement start time is a time at which movement starts, for example, a train departure time. The movement start position name is a name of a position where movement starts, for example, a station name. The movement start position is the latitude and longitude of the position where movement starts. The arrival time is the time when the movement ends, for example, the time when the train arrives at the transfer station or the destination. The arrival position name is the name of the position where the movement ends, for example, the name of the station.

Returning to FIG. 2, the positioning unit 14 measures the current position based on the signal received by the receiving unit 17 from the GPS satellite 2 (FIG. 1). The positioning unit 14 measures the current position that is the starting position of the route search when the movement route determination unit 12 performs a route search. In addition, the positioning unit 14 periodically measures the current position used for the position related service. The positioning unit 14 outputs the latitude and longitude of the measured current position.
The positioning control unit 13 determines a time interval at which the positioning unit 14 measures the current position. The waiting time timer unit 15 counts the remaining time until the movement start time. The waiting time timer unit 15 counts down the timer value as needed as time elapses.
The waiting position storage unit 21 stores a waiting position. The waiting position here is a movement start position of the next movement to be performed.
The positioning control mode storage unit 23 stores a positioning control mode. The positioning control mode storage unit 23 stores either the normal cycle mode or the long cycle mode as the positioning control mode. The normal cycle mode is a mode in which the positioning unit 14 performs positioning in a 5-minute cycle that is a normal positioning cycle, and the long cycle mode is a mode in which the positioning unit 14 performs positioning in a 10-minute cycle that is a standby positioning cycle. The destination storage unit 24 stores the destination set by the destination setting unit 10.

The transmission unit 16 transmits a location related service request signal for receiving location related service information. The location related service request signal includes location information measured by the positioning unit 14. The receiving unit 17 receives a signal for positioning from the GPS satellite 2 (FIG. 1). The receiving unit 17 receives location related service information. The positioning timer unit 18 counts the remaining time until the positioning unit 14 performs next positioning. The positioning timer unit 18 counts down the timer value as needed over time.
Note that the movement route determination unit 12 may display a plurality of movement routes on the display unit 32. In this case, the movement route determination unit 12 selects one of the displayed movement routes according to a user input operation.

FIG. 4 is a flowchart illustrating a processing procedure in which the mobile terminal device 3 controls the positioning interval based on the movement start time.
The mobile terminal device 3 starts processing for controlling the positioning interval by an input operation for setting route search conditions.
In step S301, the mobile terminal device 3 sets route search conditions. First, the destination setting unit 10 sets a destination for route search based on a user input operation. The destination arrival scheduled time setting unit 11 sets the destination arrival scheduled time based on the input operation of the user. In addition, the movement route determination unit 12 requests position information from the positioning unit 14. The positioning unit 14 measures the current position and inputs the position information to the movement route determination unit 12. The positioning control unit 13 writes the destination set by the destination setting unit 10 in the destination storage unit 24. The positioning control unit 13 sets the positioning timer unit 18 to the normal positioning cycle.

In step S <b> 302, the movement route determination unit 12 performs a route search based on the set destination and destination arrival scheduled time and the position information input from the positioning unit 14, and determines the movement route determined by the route search. Information is input to the display unit 32, and the display unit 32 displays the movement route. In addition, the travel route determination unit 12 writes travel route information in the travel route information storage unit 22.
In step S303, the positioning control unit 13 determines whether there is a waiting time around the current position. Specifically, the positioning control unit 13 reads the latest movement start position after the current time from the movement route information storage unit 22. The positioning control unit 13 calculates the distance between the read movement start position and the current position measured by the positioning unit 14, and compares the calculated distance with 1 km which is a predetermined movement start position stay determination distance. The positioning control unit 13 determines that there is a waiting time around the current position when the calculated distance is less than or equal to the movement start position stay determination distance, and waits around the current position when the calculated distance is greater than the movement start position stay determination distance. Judge that there is no. If it is determined in step S303 that there is a waiting time around the current position (step S303: YES), the process proceeds to step S304. If not (step S303: NO), the process proceeds to step S307.

In step S304, the positioning control unit 13 sets the waiting time timer unit 15 to the waiting time. Specifically, the positioning control unit 13 reads the latest movement start information after the current time from the movement route information storage unit 22. The positioning control unit 13 sets the difference between the read movement start time and the current time in the waiting time timer unit 15. In step S305, the positioning control unit 13 sets the positioning timer unit 18 to the standby positioning cycle. In step S306, the positioning control unit 13 writes the movement start position read in step S303 in the waiting position storage unit 21.
In step S307, the positioning control unit 13 determines whether or not the timer value of the positioning timer unit 18 is 0 or less. When it is determined that the value is 0 or less (step S307: YES), the process proceeds to step S308. When it is determined that the value is not 0 or less (step S307: NO), the process proceeds to step S316.

  In step S308, the positioning unit 14 measures the current position. In step S309, the transmission unit 16 transmits a location-related service request signal including the location information generated by the positioning unit 14. In step S310, the positioning control unit 13 determines whether the destination has been reached. Specifically, the positioning control unit 13 reads the destination from the destination storage unit 24. Then, the positioning control unit 13 calculates a distance between the read destination and the current position measured by the positioning unit 14, and compares the calculated distance with 1 km that is a predetermined destination arrival determination distance. The positioning control unit 13 determines that the destination has arrived when the calculated distance is equal to or less than the destination arrival determination distance, and determines that the destination has not arrived when the calculated distance is greater than the destination arrival determination distance. If it is determined in step S310 that the vehicle has arrived at the destination (step S310: YES), the mobile terminal device 3 ends the process for controlling the positioning interval. After the processing is completed, the mobile terminal device 3 performs positioning at every normal measurement cycle and transmits a location-related service request signal. In step S310, if the destination has not been reached (step S310: NO), the process proceeds to step S311.

In step S311, the positioning control unit 13 determines whether the user has left the waiting position. Specifically, the waiting position is read from the waiting position storage unit 21, and the distance between the current position measured by the positioning unit 14 and the waiting position is calculated. The positioning control unit 13 determines that the user has left the waiting position when the calculated distance is greater than the movement start position stay determination distance, and determines that the user has not left the waiting position when the distance is equal to or less than the movement start position stay determination distance. . If it is determined in step S311 that the user has left the waiting position (step S311: YES), the process proceeds to step S312. If it is determined that the user has not left (step S311: NO), the process proceeds to step S313.
In step S312, the positioning control unit 13 resets the waiting time timer unit 15 to zero. In step S313, the positioning control unit 13 reads the positioning control mode from the positioning control mode storage unit 23, and determines whether or not the read positioning control mode is the normal cycle mode. When it is determined that the normal cycle mode is selected (step S313: YES), the process proceeds to step S314, and when not (step S313: NO), the process proceeds to step S315.

In step S314, the positioning control unit 13 sets the positioning timer unit 18 to 5 minutes of the normal positioning cycle. Thereafter, the process proceeds to step S316. In step S315, the positioning control unit 13 sets the positioning timer unit 18 to 10 minutes of the standby positioning cycle.
In step S316, the positioning control unit 13 determines whether or not the timer value of the waiting time timer unit 15 is greater than zero. When it is larger than 0 (step S316: YES), the process proceeds to step S317, and when it is 0 or less (step S316: NO), the process proceeds to step S318.
In step S317, the positioning control unit 13 writes the long cycle mode in the positioning control mode storage unit 23. Thereafter, the process proceeds to step S307. In step S318, the positioning control unit 13 writes the normal cycle mode in the positioning mode storage unit 23. Thereafter, the process proceeds to step S303.

As described above, the mobile terminal device 3 determines the waiting time, which is a time during which the movement is small, from the information on the movement route obtained by the route search. The mobile terminal device 3 lengthens the positioning interval of the positioning unit 14 during the determined waiting time. Thereby, the power consumption by measuring the present position regularly can be reduced without being based on the area of the base station or the timing of the user's operation.
Note that when the positioning control mode is the long cycle mode, the positioning unit 14 may stop the positioning. For example, the positioning timer unit 18 has a function of temporarily stopping the countdown. The positioning control unit 13 stops the countdown of the positioning timer unit 18 in step S317. On the other hand, in step S318, the positioning control unit 13 restarts the countdown of the positioning timer unit 18. Thereby, the positioning control unit 13 controls the positioning unit 14 to stop positioning when the positioning control mode is the long cycle mode. Thereby, the power consumption by positioning can be further reduced.
Alternatively, the mobile terminal device 3 may transmit a route search request signal without performing route search by itself, and may receive the information on the travel route generated by the information server device 5. Thereby, the portable terminal device 3 does not need to include the movement route determination unit 12, and the circuit scale can be reduced.
In addition, when the mobile terminal device 3 is located at the movement start position even after the movement start time has passed, or when the mobile terminal device 3 is separated from the movement start position by a predetermined distance or more during the waiting time, the movement route is determined. The unit 12 may perform a route search again. Thereby, the mobile terminal device 3 controls the positioning interval of the positioning unit 14 after updating the movement start information to appropriate information suitable for the current situation, so that more appropriate control can be performed.

The time interval of positioning performed by the positioning unit 14 is not limited to 5 minutes and 10 minutes, and the time interval of the standby positioning cycle may be longer than the time interval of the normal positioning cycle.
Note that the mobile terminal device 3 may use three or more positioning control modes. For example, during the waiting time, positioning is performed at 10-minute intervals in the long cycle mode until 20 minutes before the movement start time, and when within 20 minutes before the movement start time, the side is stopped until the movement start time as the positioning stop mode. May be. Thereby, the portable terminal device 3 provides the user with information near the current position when the waiting time is long. The user can perform an activity using waiting time such as searching for a store near the current position by referring to the provided information. On the other hand, when the waiting time decreases, the mobile terminal device 3 can stop positioning and reduce power consumption.

The IC card unit 50 is an application unit that functions as a responder of a contactless ID (Identifier) system. The IC card unit 50 receives a signal indicating that it has entered the ticket gate or a signal indicating that it has gone out of the ticket gate from the automatic ticket gate device when passing through the automatic ticket gate at the railway station. When the IC card unit 50 receives a signal indicating that it has entered the ticket gate or a signal indicating that it has gone out of the ticket gate, the IC card unit 50 inputs the received signal to the specific movement detection unit 51.
The specific movement detection unit 51 determines that movement by the train starts when it detects a signal input from the IC card unit 50 and indicates that it has entered the ticket gate, and if it detects a signal that indicates that it has gone out of the ticket gate, It is determined that the movement has ended.
In addition, the specific movement detection unit 51 is connected to the external device 500. When the specific movement detection unit 51 detects a signal input from the external device 500 indicating that the vehicle has entered the highway, the specific movement detection unit 51 determines that the movement using the highway has started, and detects a signal indicating that the vehicle has exited the highway. It is determined that the movement using the expressway has ended.
The external device 500 is a device that outputs a signal indicating that the vehicle has entered an expressway or exited from an expressway through an interchange, such as a car navigation system or an ETC (registered trademark) device installed in an automobile. The external device 500 inputs the above signal to the specific movement detection unit 51 through Bluetooth (registered trademark) communication. Note that the external device 500 may input the above signal to the specific movement detection unit 51 by other communication means such as infrared communication or wired communication. Hereinafter, a signal indicating that the vehicle has entered the ticket gate or has exited the ticket gate and a signal indicating that the vehicle has entered or exited the highway are also referred to as a specific position signal.

The station flag storage unit 26 stores a station flag indicating whether or not the mobile terminal device 7 is moving using a railway. A station flag value of 1 indicates that the train is moving, and a station flag value of 0 indicates that the train is not moving. The expressway flag storage unit 27 stores an expressway flag indicating whether or not the mobile terminal device 7 is moving using the expressway. A highway flag value of 1 indicates that the vehicle is moving using a highway, and a highway flag value of 0 indicates that the vehicle is not moving using a highway.
While traveling using a transportation means that occupies an area distinguished from the outside, such as a railroad or a highway, the current position is only a passing point, and information around the current position is not considered important. In this case, frequent current location measurement and frequent location-related service information need not be provided. Therefore, when the mobile terminal device 7 detects movement using a transportation means that occupies an area distinguished from the outside, the mobile terminal device 7 lengthens the measurement time interval of the current position to reduce power consumption.

FIG. 8 is a flowchart illustrating a processing procedure in which the mobile terminal device 7 acquires the specific position signal and controls the positioning interval.
When the power is turned on, the mobile terminal device 7 acquires a specific position signal and starts processing for controlling the positioning interval. In addition, the mobile terminal device 7 receives a specific position signal and controls the positioning interval to obtain an instruction to start the processing in a state where the processing (FIG. 4) for controlling the positioning interval is not performed based on the movement start time. When input is made from 31, this process is started.
In step S <b> 601, the positioning control unit 53 writes 0 in the station flag storage unit 26 and 0 in the expressway flag storage unit 27. In addition, the positioning control unit 53 writes the normal cycle mode in the positioning control mode storage unit 23. When the user uses the external device 500, the mobile terminal device 7 starts communication with the external device 500 according to the user's operation.

In step S <b> 602, the specific movement detection unit 51 determines whether or not it is a movement start using a railway. Specifically, the specific movement detection unit 51 determines that the movement starts using the railroad when the signal indicating that the ticket has entered the ticket gate is input from the IC card unit 50, and otherwise uses the railroad. It is determined that the movement has not started. If it is determined that the movement starts using the railroad (step S602: YES), the process proceeds to step S603, and if not (step S602: NO), the process proceeds to step S604. In step S <b> 603, the specific movement detection unit 51 inputs a signal indicating that movement is started using a railroad to the positioning control unit 53, and the positioning control unit 53 sets the station flag 26 to 1.
In step S604, the specific movement detection unit 51 determines whether or not the movement using the railway has ended. Specifically, the specific movement detection unit 51 determines that the movement using the railroad has ended when a signal indicating that the vehicle has gone out of the ticket gate is input from the IC card unit 50, and otherwise uses the railroad. It is determined that the movement has not been completed. If it is determined that the movement using the railroad has ended (step S604: YES), the process proceeds to step S605. If not (step S604: NO), the process proceeds to step S606. In step S <b> 605, the specific movement detection unit 51 inputs a signal indicating that the movement using the railway has ended to the positioning control unit 53, and the positioning control unit 53 resets the station flag 26 to 0.

In step S606, the specific movement detection unit 51 determines whether or not to start moving on the expressway. Specifically, the specific movement detection unit 51 determines that the movement using the highway is started when the signal indicating that the vehicle has entered the highway is input from the external device 500, and if not, the specific movement detection unit 51 determines the highway. It is determined that the movement is not started. If it is determined that the movement starts using the expressway (step S606: YES), the process proceeds to step S607, and if not (step S606: NO), the process proceeds to step S608. In step S <b> 607, the specific movement detection unit 51 inputs a signal indicating that the movement is started using the highway to the positioning control unit 53, and the positioning control unit 53 sets the highway flag 27 to 1.
In step S608, the specific movement detection unit 51 determines whether or not the movement on the highway is finished. Specifically, the specific movement detection unit 51 determines that the movement using the highway has ended when a signal indicating that the vehicle has exited the highway is input from the external device 500, and if not, the specific movement detection unit 51 determines the highway. It is determined that the movement has not been completed. If it is determined that the movement using the highway has ended (step S608: YES), the process proceeds to step S609. If not (step S608: NO), the process proceeds to step S610. In step S <b> 609, the specific movement detection unit 51 inputs a signal indicating the end of movement on the highway to the positioning control unit 53, and the positioning control unit 53 resets the highway flag 27 to 0.

In step S610, the positioning control unit 53 determines whether or not the timer value of the positioning timer unit 18 is zero. If it is 0 (step S610: YES), the process moves to step S611. If it is not 0 (step S610: NO), the process moves to step S613.
In step S611, the positioning unit 14 measures the current position. In step S612, the transmission unit 16 transmits a location-related service request signal including the location information generated by the positioning unit 14.
In step S613, the positioning control unit 53 reads the railway flag from the railway flag storage unit 26, and determines whether the value of the read railway flag is 1. If it is determined to be 1 (step S613: YES), the process proceeds to step S614. If not (step S613: NO), the process proceeds to step S615. In step S614, the positioning control unit 53 sets the positioning timer unit 18 to 10 minutes of the railway moving positioning cycle.

In step S615, the positioning control unit 53 reads the highway flag from the highway flag storage unit 27, and determines whether the value of the read highway flag is 1. If it is determined to be 1 (step S615: YES), the process proceeds to step S616. If not (step S615: NO), the process proceeds to step S617. In step S616, the positioning control unit 53 sets the positioning timer unit 18 to 10 minutes of the positioning period during highway movement.
In step S617, the positioning control unit 53 sets the positioning timer unit 18 to 5 minutes of the normal positioning cycle.
In step S618, the positioning control unit 53 determines whether there is an operation input for ending the process. When it is determined that there is an operation input for ending the process (step S618: YES), the mobile terminal device 7 ends the process of acquiring the specific position signal and controlling the positioning interval. After the processing is completed, the mobile terminal device 7 performs positioning every 5 minutes, which is a normal positioning cycle, and transmits a position-related service request signal. On the other hand, if it is determined in step S618 that there is no operation input for ending the process (step S618: NO), the process proceeds to step S602.

As described above, the mobile terminal device 7 can reduce power consumption by increasing the positioning interval when detecting movement using a transportation means having an area distinguished from the outside.
Note that the information server device 5 (FIG. 1) may calculate the current location of the mobile terminal device 7 from location information received in the past and transmit location-related service information. For example, the information server device 5 reads the position of the portable terminal device 7 (hereinafter, also referred to as the latest position) from the position information received most recently, and also determines the position of the portable terminal device 7 from the position information received immediately before ( (Hereinafter also referred to as the previous position). The information server device 5 calculates the moving direction and moving speed of the mobile terminal device 7 by taking the difference between the latest position and the previous position. The information server device 5 calculates the current position when the mobile terminal device 7 continues to move at the calculated speed in the calculated direction every 5 minutes. Each time the information server device 5 calculates the current location of the mobile terminal device 7, the information server device 5 transmits location-related service information related to the calculated current location. Thereby, the portable terminal device 7 can receive the position related service information while extending the positioning interval to reduce the power consumption.
In the above case, the information server device 5 may calculate the location of the mobile terminal device 7 in the future, such as two minutes later, and transmit location-related service information related to the calculated location. Thereby, when the portable terminal device 7 continues to move in a certain direction, it is possible to receive the location-related service information of the destination to be moved.
In step S606, different times may be set depending on whether the positioning control mode is the station mode or the highway mode.
Instead of the station flag storage unit 26 and the highway flag storage unit 27, the position related information service unit 102 may include one specific position signal flag. In this case, the positioning control mode storage unit 23 stores the specific position mode as a mode common to the station mode and the expressway mode in step S613 or step S614. The positioning control unit 53 sets 10 minutes in the positioning timer unit 18 when the positioning control mode is the specific position mode in step S606. Thereby, a storage area can be reduced.

<Fourth Embodiment>
FIG. 9 is a configuration diagram showing a schematic configuration of the mobile terminal device 8 according to the fourth embodiment of the present invention.
In the figure, the mobile terminal device 8 includes a route search unit 101, a position related information service unit 702, a positioning unit 14, a transmission unit 76, a reception unit 17, a positioning timer unit 18, and a data transmission control unit 75. Is done. The route search unit 101 includes a destination setting unit 10, a destination arrival scheduled time setting unit 11, and a movement route determination unit 12. The position related information service unit 702 includes a waiting time timer unit 15, a positioning control unit 73, a waiting position storage unit 21, a movement route information storage unit 22, a positioning control mode storage unit 23, a destination storage unit 24, and a transmission position information flag storage. A unit 28 and a position history storage unit 29 are included.
In the figure, the same reference numerals (101, 10-12, 15, 21-24, 14, 17, 18) are assigned to portions corresponding to the respective portions of the mobile terminal device 3 of FIG.

The position history storage unit 29 stores the position information measured by the positioning unit 14 as the position history.
The transmission position information flag storage unit 28 stores a transmission position information flag. Here, the transmission position information flag is a flag indicating whether or not the position history storage unit 29 stores position information. When the position history storage unit 29 stores position information, the positioning control unit 73 writes 1 to the transmission position information flag storage unit 28, and otherwise writes 0.
The data transmission control unit 75 inputs the presence / absence of transmission data to the positioning control unit 73. In addition, the data transmission control unit 75 receives a position history input from the positioning control unit 73. The data transmission control unit 75 transmits the input position history together with other data to the base station device 4 (FIG. 1) via the transmission unit 76.

FIG. 10 is a flowchart illustrating a processing procedure in which the mobile terminal device 8 transmits the location information collectively. When the mobile terminal device 8 is turned on, the mobile terminal device 8 starts a process of transmitting the location information collectively. In the figure, steps corresponding to the steps in FIG. 4 are denoted by the same reference numerals (S301 to S318), and description thereof is omitted.
After step S308, the mobile terminal device 8 proceeds to step S801.
In step S801, the positioning control unit 73 writes the current position determined by the positioning unit 14 in step S308 in the position history storage unit 29 in association with the positioning time.
In step S802, the positioning control unit 73 determines whether the data transmission control unit 75 transmits data other than the position information. If the data transmission control unit 75 performs transmission (step S802: YES), the process proceeds to step S803, and if not (step S802: NO), the process proceeds to step S310.
In step S <b> 803, the positioning control unit 73 reads the position history from the position history storage unit 29 and inputs the position history to the data transmission control unit 75. The data transmission control unit 75 inputs the input position history to the transmission unit 76 together with other data. The transmission unit 76 transmits the input position history and other data. Thereafter, the process proceeds to step S310.

As described above, the mobile terminal device 8 transmits the position history together with other data. As a result, the mobile terminal device 8 can transmit the position information in a packet of other data to reduce power consumption. In particular, when the mobile terminal device 8 is moving, the location history is transmitted each time the base station area in which the mobile terminal device 8 is located changes, so that it is possible to receive location-related service information of the destination.
Similarly to the case of the second embodiment, the information server device 5 (FIG. 1) may calculate the current position by determining the moving direction of the mobile terminal device 8 from the received position history. Thereby, the information server device 5 can calculate the current location of the mobile terminal device 8 and transmit the location-related service information even at the timing when the location information or the location history is not received.
In step S805, if the number of location histories stored in the location history storage unit 29 is greater than a predetermined minimum transmission number, whether or not the data transmission control unit 75 transmits other data. Regardless, the process may move to step S806. In step S805, the positioning control unit 73 reads the position history from the position history storage unit 29 and inputs the position history to the data transmission control unit 75. The data transmission control unit 75 transmits the input position history via the transmission unit 76 regardless of the presence or absence of other data to be transmitted. Thereby, the portable terminal device 8 can transmit a location history and receive location-related service information at least in a cycle in which the positioning unit 14 performs positioning the minimum number of times of transmission.

A program for realizing all or part of the functions of the mobile terminal devices 3, 6, 7, and 8 is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read into a computer system. The processing of each unit may be performed by executing. Here, the “computer system” includes an OS and hardware such as peripheral devices.
Further, the “computer system” includes a homepage providing environment (or display environment) if a WWW system is used.
The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory in a computer system serving as a server or a client in that case, and a program that holds a program for a certain period of time are also included. The program may be a program for realizing a part of the functions described above, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system.
