Four or more (24 or more in total) of the GPS satellites 60 are arranged for each of six kinds of orbital planes whose ascending intersection longitude at an altitude of about 20,000 km on the earth is every 60 degrees for 12 hours. Around the earth in a cycle of. By this orbital movement, the same GPS satellites 60 arrive at the same time every day, and at least 4 (normally 5 to 6) GPS satellites 60 can always be seen from any point on the earth. The position information of the GPS satellite 60 is strictly managed by five monitoring stations on the ground. The GPS satellite 60 is equipped with an atomic clock (oscillator) such as cesium (Cs) or rubidium (Rb), and accurate time is recorded. The frequency of the oscillator is 10.23 MHz, the clock is obtained by dividing it by 1/10, and the time of each GPS satellite is also accurately synchronized.
From the GPS satellite 60, radio waves of two frequencies of 1575.42 MHz (L1) and 1227.60 MHz (L2) are repeatedly transmitted at intervals of about 1 ms. This radio wave is modulated by a random code called a pseudo random code (Pseudo Random Noise Code) with a predetermined code. When it is received by the mobile phone 10, the signal content is decoded by referring to a code corresponding to the random number table. Then, based on the code and the time data output from the clock unit of the mobile phone 10, the time difference of the signal between the time when the radio wave is emitted from the GPS satellite 60 and the time received by the mobile phone 10 is measured. Then, by multiplying this time difference by the propagation speed of radio waves, the distance from the GPS satellite 60 to the mobile phone 10 (= propagation speed × time difference) can be obtained. In addition, since accurate information on the orbit is sent from the GPS satellite 60, the current position of the GPS satellite 60 can be accurately known. Therefore, if the distance from the GPS satellite 60 is known, it can be seen that the mobile phone 10 is somewhere on the spherical surface with the radius determined from the GPS satellite 60 as the center. If radio waves from two GPS satellites 60 can be received, two spherical surfaces are obtained, and the position of the mobile phone 10 is somewhere on the circumference where the two spheres intersect. When radio waves from the three GPS satellites 60 can be received, one of the two points where the three spherical surfaces intersect is the position of the mobile phone 10. Since one of the two points is far from the position where it can be predicted, it can be discarded, so that one point is determined in principle.
However, in reality, the calculated answer (the intersection of the three surfaces) does not become two points due to the measurement error. Most of the measurement errors are due to the accuracy of the timepiece mounted on the mobile phone 10. The clock of the GPS satellite 60 is an atomic clock, but the accuracy of the clock mounted on the mobile phone 10 is far inferior to that of an atomic clock. For this reason, a large error occurs in the calculated value of the time difference.
Therefore, the GPS receives radio waves from another GPS satellite, that is, the fourth GPS satellite. This can be thought of as follows. That is, when three unknowns of XYZ were obtained from the information (equation) of three GPS satellites, calculation was not possible because there was another unknown amount of the clock error in the mobile phone 10 on the receiving side. Is to solve this problem by introducing new information (equation). By receiving radio waves from four GPS satellites, it is possible to obtain a substantially accurate position that converges to one point in GPS. Further, the remaining error is an error included in the information content from the GPS satellite and an atmospheric disturbance until the radio wave reaches the mobile phone 10 from the GPS satellite. Regarding the former information from GPS satellites, S / A (Selective Availability) was originally intended to add an error for private use, but it was canceled in May 2000. Can obtain information with little error. Further, the GPS satellite also sends data for correcting the delay amount due to the latter ionosphere, and can be corrected by receiving radio waves of two frequencies with the mobile phone 10 on the receiving side. This is because it is known that the radio wave propagation delay amount due to the ionosphere is inversely proportional to the frequency.
The GPS receiver 130 calculates and outputs the data of the mobile phone position information (latitude, longitude, altitude) corrected in this way.

The GPS positioning accuracy, which is accuracy information of the GPS position information, can be expressed by “DOP (Dilution of Presision)”, “2drms”, or the like.
The DOP is also called a “decrease rate of accuracy”, and is a numerical value that serves as an indicator of degradation of GPS positioning accuracy. A smaller DOP value means higher accuracy. As described above, GPS positioning is usually performed using four or more GPS satellites, but the positioning accuracy greatly depends on the arrangement state of the GPS satellites at that time. The value of DOP is determined by the arrangement state of the GPS satellites. For example, if the GPS satellites are evenly distributed, the value of the DOP decreases and the GPS positioning accuracy increases, and conversely, if the GPS satellites are biased to one place, the DOP The value increases and the GPS positioning accuracy decreases.
The value of DOP can be calculated by the following equation. Here, l, m, and n in the equation are cosines in the direction of the coordinate axes x, y, and z of the unit length vector from the measurement point on the earth toward the GPS satellite, respectively. k is the number of visible GPS satellites. 2σ is an error expansion coefficient in each subscript direction.

  In the case of 2drms (2 × distance root mean square), the smaller the value, the higher the accuracy. When a GPS receiver is installed at one fixed location and continuously positioned, a random ranging error is introduced, so that one positioning point is not determined. The random error multiplied by twice HDOP is 2 drms. Here, it is said that about 95% of all scattered positioning points fall within a circle with a radius of 2 drms centered on the true positioning points.

  In the present embodiment, the DOP value is used as accuracy information, the position accuracy notation when the DOP value is 3 or less is “A” (good), and the DOP value is greater than 3. The accuracy notation is [B] (normal).

  The GPS position measurement method described so far is called “single positioning” in which the position is independently determined by only one GPS receiver (mobile phone). In order to further improve the measurement accuracy, a correction value may be calculated by an external receiving device located at a position different from the measurement point, and the actual measurement value may be corrected based on the data. This correction method is called “relative positioning (D-GPS)” or the like for independent positioning. As specific correction methods, there are various methods such as obtaining the phase of a carrier wave from a GPS satellite. The accuracy of “single positioning” is 10 m or less, but if it is corrected by “relative positioning (D-GPS)”, the accuracy can be increased to about 1 cm at the maximum.

Therefore, even when complicated information analysis processing for obtaining movement prediction information of the mobile phone 10 is required, it is not necessary to execute the information analysis processing in the mobile phone 10 and increase the information processing load on the mobile phone 10. Can be suppressed.

  FIG. 9 is a flowchart illustrating an example of an operation of acquiring and transmitting position information in the mobile phone 10 having the above configuration. The service for transmitting and managing the location information of the user's mobile phone 10 to the movement history server 30 is provided in a state in which the user has previously received consent for the use of the service.

In FIG. 9, after the mobile phone 10 is turned on, when the position information acquisition / transmission mode is selected, the following operation is performed. First, it is preferentially determined whether or not there is communication with a communication terminal device such as the ticket gate device 70 fixedly arranged in various facilities (step S1). Here, when there is communication with the communication terminal device, the facility position information received from the communication terminal device by the communication is stored in the internal memory 112 and transmitted to the movement history server 30 (step S2).
Next, it is determined whether or not it is time to acquire GPS position information (step S3). For example, a predetermined time interval (for example, one minute interval) is set as the GPS position information acquisition timing, and it is determined whether or not the time data output from the clock unit 125 has reached the acquisition timing.
In the case of the acquisition timing of the GPS position information, it is determined whether or not the radio wave from the GPS satellite 60 can be received with a predetermined intensity based on the output of the GPS receiving unit 130 constituting the GPS position information means 102. (Step S4).
Here, when it is determined that the radio wave from the GPS satellite 60 can be received at a predetermined intensity, the GPS position information (latitude, longitude, altitude) is obtained based on the radio wave reception signal received from the GPS satellite 60. Calculated and acquired, stored in the internal memory 112 and transmitted to the movement history server 30 (step S5). Further, area position information (base station address) is acquired by the area position information receiving means 103, stored in the internal memory 112, and transmitted to the movement history server 30 (step S6).
On the other hand, if it is determined that the radio wave from the GPS satellite 60 is not receivable at a predetermined intensity, the area position information receiving unit 103 acquires the area position information (base station address) without acquiring the GPS position information. Then, it is stored in the internal memory 112 and transmitted to the movement history server 30 (step S7).

  In the example of FIG. 9, each time the position information is acquired and stored, each time the position information is transmitted to the movement history server 30. A plurality of pieces of position information may be collectively transmitted to the movement history server 30 after the acquisition and storage are continuously executed a plurality of times. In this case, an increase in communication load can be suppressed as compared with the case of transmitting each time position information is acquired and stored.

FIG. 10 is a sequence diagram illustrating an example of a processing procedure for inquiring from the mobile phone 10 to the movement history server 30 where the user of the mobile phone 10 has been in the past.
The service for searching and transmitting the movement history information, which is the history of the past location information of the mobile phone 10 of the user, in the movement history server 30 is the user who uses the service and the movement history information provided. It is provided in a state in which prior consent has been obtained from both users of mobile phones corresponding to the above.

  In FIG. 10, first, the user operates the mobile phone 10 to display an inquiry screen as shown in FIG. 11 on the screen 119 a of the display unit 119. In this inquiry screen, when the user inputs an inquiry condition for date and time and clicks the “Send button” 163, an inquiry request for requesting movement history information that matches the inquiry condition as well as the inquiry condition input by the user. Is transmitted to the movement history server 30.

  The movement history server 30 automatically creates an inquiry command sentence (for example, an SQL sentence) based on the inquiry condition received from the mobile phone 10, searches the location information storage means 301, and matches the inquiry condition received from the mobile phone 10. Extract movement history information. Next, the movement history server 30 transmits the extracted movement history information to the mobile phone 10 via the mobile phone communication network 20. Here, if the extracted movement history information is position information such as latitude and longitude, and is not a place name or facility name that is easy for the user to understand, the information is converted into a place name or facility name and then transmitted to the mobile phone 10.

The mobile phone 10 may receive the movement history information of the inquiry result transmitted from the movement history server 30 and display the inquiry result as shown in FIGS. 12A to 12D on the screen 119a of the display unit 119. it can. In FIG. 12, “IC information” is displayed because the facility location information is acquired using an IC card or an IC chip.
FIG. 12A shows an example of an inquiry result when the position accuracy of the GPS position information at the date and time of inquiry is “A” (good). In this case, the position information of the inquiry result is displayed in a complete format such as “Roppongi Hills”, and the address is also displayed in detail. When a “map” button 153 in the inquiry result screen 152 is clicked, a map image centered on the position information of the inquiry result can be displayed.
FIG. 12B shows an example of an inquiry result when the position accuracy of the GPS position information at the date and time of inquiry is “B” (normal). In this case, the position information of the inquiry result is displayed as “˜near” and the address of the address is omitted.
FIG. 12C shows an example of an inquiry result when there is IC information (facility location information) at the date of inquiry. In this case, there is IC information (facility location information) acquired from the ticket gate device at the station, and it is displayed that the station is moving between stations.
FIG. 12D shows an example of an inquiry result when neither GPS position information nor facility position information exists at the date and time of inquiry. In this case, since there is neither GPS position information nor IC information (facility position information) corresponding to the date and time of inquiry, the base station of the communication management area (cell) in which the mobile phone 10 was located at that date and time Information (base station address) is displayed.

  As described above, by storing the location information of the user's mobile phone in the movement history server 30 or by searching and using the movement history information in the movement history server 30, the user can save his / her past movement history. Can be saved and referenced. And if various other additional information is preserve | saved as needed with a positional information and date information, a user's detailed action | operation history can be referred. For example, “When and where did you eat?”, “When and where did you meet?”, “When and where did you buy what?”, “When and where did you talk with whom?” You can refer to "Where have you been?", "Why were you happy when and where?"

Note that the inquiry condition for the movement history information is not limited to the condition for inquiring where the user was at a specific date and time (for example, 14:00 on February 19, 2003) as in the above example. For example, the following inquiry conditions (1) to (3) may be used.
(1) Inquiry: What is the action on a specific day (for example, August 15, 2002)?
Sample results: time and location information list (2) When did you go to Kyoto in the past?
Example of results: “October 15-18, 2001, August 22-23, 2002”
(3) Have you ever met me and Mr. B?
Example of the result: “It seems that they were very close to each other in Roppongi 1-chome at 13:45 on April 5, 1998.”

  The movement history information of the inquiry result transmitted to the mobile phone 10 when the inquiry about the action on the specific day (1) (for example, August 15, 2002) is made is the time information at the point corresponding to the position information. It may be image information of a map attached with. For example, as shown in FIG. 13, the time data (“9:00”, “12:00”, “15:00”) that the user was at the location on the map image 154 where the location information exists. , “18:00”, “21:00”). In this case, it is possible to visually confirm how the user has moved over time on the map image 154.

As described above, according to the present embodiment, when the mobile phone 10 as a mobile communication terminal moves to a place where radio waves from the GPS satellite 60 can be received, the GPS satellite 60 is received by the GPS position information acquisition unit 102. GPS position information can be acquired based on the reception result of radio waves from. In addition, when the mobile phone 10 moves into the communication management area, the mobile phone 10 can acquire area position information related to the communication management area in which the mobile phone 10 is located by the area position information acquisition unit 102. . When the user of the mobile phone 10 passes through or stays at a facility where a communication terminal device such as the ticket gate device 70 capable of communicating with the mobile phone 10 is installed, the mobile phone 10 communicates with a communication terminal device such as the above-described ticket gate device 70, and acquires facility location information that can specify the location of the facility from the communication terminal device. As described above, even when the mobile phone 10 is moving in a place where the radio wave from the GPS satellite 60 cannot be received and is not within the communication management area, the communication terminal device such as the ticket gate device 70 is installed. The facility location information can be acquired when passing through or staying at a facility. The mobile phone 10 transmits a plurality of types of position information including at least the facility position information to the movement history server 30 as the information processing apparatus together with the date / time information when the information is acquired.
As described above, the ticket gate apparatus 70 is capable of receiving a radio wave from the GPS satellite 60 and moving in a place that is not within the communication management area of the cellular phone communication network 20 as a mobile communication network. It is possible to acquire and transmit facility location information that can specify the location of the facility when passing or staying at the facility where the communication terminal device is installed. Therefore, it is possible to increase the opportunity for acquiring the position information of the mobile phone 10 in a place where the GPS position information and the area position information cannot be acquired, and the movement history server 30 can use highly accurate movement history information regarding the user of the mobile phone 10. become.

  In addition, according to the present embodiment, the movement history server 30 associates each piece of position information received from the mobile phone 10 with the date / time information and user identification information when the information is acquired. It is stored in the movement history database (301). The movement history server 30 can manage a movement history indicating what point the user of the mobile phone 10 has moved with the passage of time based on the stored position information. The movement history information can be provided in response to a request from the user himself / herself or a third party. In addition, when moving history information is provided to a third party, the user himself / herself must consent to the provision of moving history information to the third party.

  In particular, according to the present embodiment, all of the three types of position information, that is, the GPS position information, the area position information, and the facility position information can be acquired and transmitted to the movement history server 30. In this case, it is possible to further increase the opportunity to acquire the position information of the mobile phone 10, provide highly accurate movement history information, and increase the degree of freedom of position information included in the movement history information provided from the movement history server 30. .

  Further, according to the present embodiment, when the mobile phone 10 acquires the GPS location information, the mobile phone 10 calculates accuracy information for the GPS location information and transmits the accuracy information to the movement history server 30 together with the GPS location information. Can do. The movement history server 30 can determine the accuracy of each GPS position information by storing the accuracy information for the GPS position information together with the GPS position information received from the mobile phone 10. In particular, when the movement history information is searched by accessing the movement history server 30 from a communication terminal, the accuracy information is displayed together with the GPS position information received from the movement history server 30, thereby performing the search. Can determine the reliability of the GPS position information.

  Further, according to the present embodiment, the acceleration information and the posture information of the mobile phone 10 can be acquired when moving in an area where the GPS position information, area position information, and facility position information cannot be acquired. The acceleration information and posture information acquired by the mobile phone 10 are transmitted to the movement history server 30 together with the date / time information when the information is acquired. The movement history server 30 stores the acceleration information and posture information received from the mobile phone 10 in the position information storage unit (movement history database) 301 in association with the date / time information and the user identification information. Since the movement history server 30 can determine how and in which direction the mobile phone 10 has moved based on the stored acceleration information and attitude information, the movement history server 30 can move between the movement points corresponding to the GPS position information and the like. The user's movement trajectory can be specified by interpolation.

  Further, according to the present embodiment, it is possible to perform control so that the GPS position information acquisition unit, the area position information acquisition unit, and the facility position information acquisition unit are selectively activated. By this selective activation control of the position information acquisition means, the position information can be acquired using the optimum position information means in accordance with the accuracy of the required position information. Moreover, the power consumption in a mobile communication terminal can be suppressed by not starting the location information acquisition means which is not used for acquisition of location information.

Further, the selective activation control of the position information acquisition means 102, 103, 104 may be executed according to the movement prediction information of the mobile phone 10.
Since the position change when the mobile phone 10 moves is generally continuous, the position of the mobile phone 10 at a certain point in time and the subsequent position change are often largely related to the previous movement history. For example, in the case of a movement history where the movement history of the mobile phone 10 before a certain point in time remains in a certain place, there is a high possibility that the mobile phone 10 is used at home, office, etc. You can expect to stay in place. In the case of a movement history in which the mobile phone 10 moves at the same speed as a car or a train, the user gets on the train with the mobile phone 10 or puts the mobile phone 10 in the car and moves the car. It can be predicted that there is a high possibility of driving.
On the other hand, depending on how and where the mobile phone 10 is moving, the position information is obtained by using any of the GPS position information acquisition means 102, the area position information acquisition means 103 and the facility position information acquisition means 104. It may be better to obtain it. For example, when the user is moving in a building, it is difficult to receive radio waves from the GPS satellite 60, and the GPS position information acquisition unit 102 is inappropriate. Further, when the user is walking in the communication management area outdoors, the communication management area in which the mobile phone 10 is located does not change, and the mobile phone 10 may move within the communication management area. . In this case, the area position information acquisition unit 103 is insufficient, and the GPS position information acquisition unit 102 is suitable. When the user places the mobile phone 10 at home, office, etc., the area position information acquisition means 103 is preferable because the position of the mobile phone 10 hardly changes and it is difficult to receive radio waves from the GPS satellite 60. It is.
Therefore, when the position information of the mobile phone 10 is to be acquired, the subsequent movement of the mobile phone 10 is predicted based on the movement history of the previous mobile phone 10, and the above-described movement prediction information The selective activation control of the position information acquisition means 102, 103, 104 may be executed. By the selective activation control of the position information acquisition means, the position information of the mobile phone 10 can be acquired using the optimum position information means according to the prediction of the movement of the mobile phone 10.

  Further, in order to obtain the movement prediction information of the mobile phone 10 from the movement history information including the GPS position information, area position information, and facility position information, complicated information analysis processing is required for these position information. There is. Therefore, the movement prediction information may be received from the movement history server 30, and each position information acquisition unit may be controlled to be selectively activated based on the received movement prediction information. In this case, it is not necessary to execute complicated information analysis processing for obtaining movement prediction information of the mobile phone 10 in the mobile phone 10, and an increase in information processing load on the mobile phone 10 can be suppressed.

In addition, the location where the mobile phone 10 is located may be greatly related to the day of the week or the time zone, and it is often predicted that the mobile phone 10 is always located at a specific location on a specific day of the week or time zone. For example, some users work at a specific workplace during the daytime on weekdays, and the user's mobile phone 10 is located at that workplace. Some users spend most of their holidays on Saturdays and Sundays at home, or move to certain locations for recreation during certain holidays. The mobile phone 10 is located.
Therefore, when the location information of the mobile phone 10 is to be acquired, each of the location information acquisition means may be selectively activated according to the day of the week information or the time zone information at that time. In this case, the position information of the mobile phone 10 can be acquired using the optimum position information means corresponding to the day of the week or the time zone.

  In addition, according to the present embodiment, the location information is acquired and stored in the mobile phone 10 a plurality of times in succession, and the location information that is continuously acquired and stored is collectively transmitted to the movement history server 30. You may do it. In this case, an increase in communication load can be suppressed as compared with the case of transmitting each time position information is acquired and stored.

  Further, according to the present embodiment, communication with a communication terminal device such as the ticket gate device 70 installed in the facility is performed by the facility position information acquisition unit 104 configured using an IC chip or an IC card in the mobile phone 10. And the facility location information that can identify the location of the facility can be acquired from the communication terminal device. The IC chip or IC card constituting the facility location information acquisition means 104 has a function of performing a prepaid process when a user uses a service at the facility, and a settlement when the service is used or a product is purchased. Various functions such as a function for processing can be provided.

  Further, according to the present embodiment, the movement history server 30 sends an inquiry request for requesting movement history information that matches a predetermined inquiry condition via the mobile phone communication network 20 as a mobile communication network. Receive from a communication terminal such as a personal computer. Receiving this inquiry request, the movement history server 30 searches the position information storage means (movement history database) 301 to extract movement history information that matches the inquiry condition, and sends it to the communication terminal via the mobile phone communication network 20. Send. The user of the communication terminal can receive the movement history information that meets the desired inquiry condition and output it on the communication terminal.
