  The operation of each part of the positioning system according to the embodiment of the present invention configured as described above will be described with reference to FIGS.

  First, the operation of each part of the mobile communication device MS will be described with reference to FIG. 1 and FIG. The mobile communication network communication unit 12 outputs a high-frequency signal transmitted from the base station and received by the antenna 12a to the mobile communication network transmission / reception unit 13, and outputs a high-frequency signal output from the mobile communication network transmission / reception unit 13 to the antenna 12a. To the base station.

  The mobile communication network transmission / reception unit 13 amplifies, converts and demodulates the high frequency signal from the mobile communication network communication unit 12, and converts the digital audio signal in the channel signal according to the setting of the domestic / international mode setting function 11-1. A control signal is sent to the communication unit 14 to the control unit 11. Further, based on the quality of the high-frequency signal from the mobile communication network communication unit 12, it is determined whether the mobile communication device MS is within or outside the service area of the mobile communication network, and notifies the control unit 11.

  The mobile communication network transmission / reception unit 13 further converts the digital voice signal output from the communication unit 14 and the control signal output from the control unit 11 into a channel signal according to the setting of the domestic / overseas mode setting function 11-1. To obtain a high-frequency signal and send it to the mobile communication network communication unit 12.

  The calling unit 14 converts the digital audio signal output from the mobile communication network transmitting / receiving unit 13 into an analog audio signal, amplifies it, and sends it to the speaker 14a. Further, the analog audio signal output from the microphone 14 b is amplified, converted into a digital audio signal, and transmitted to the mobile communication network transmitting / receiving unit 13.

  The display unit 15 is an organic EL display used for a display prompting the user to operate, a display of contents operated by the user, a display of an operation state of the apparatus, or a backlit LCD. 11, image data including characters, numbers, and icons is displayed, and the displayed data is instructed from the control unit 11 in response to an input operation from the input unit 16 or an incoming signal. Switch by receiving.

  The input unit 16 is composed of a plurality of key switches, designates the telephone number of the communication partner, etc., and numeric keys for inputting hiragana characters, alphabetic characters and symbol characters by a toggle type input method, and a mobile communication device And a plurality of function keys used for inputting operation instructions such as power on and off of the MS. When the key of the input unit 16 is pressed, the identifier of the key is notified to the control unit 11.

  The positioning unit 21 first requests the positioning auxiliary information update control function 11-2 to update the positioning auxiliary information stored in the positioning auxiliary information storage unit 22. Regardless of whether or not the update is successful, the positioning unit 21 performs positioning next. That is, with reference to the positioning auxiliary information stored in the positioning auxiliary information storage unit 22, the movement from the satellite is determined based on the difference between the time when the radio wave is transmitted from the positioning satellite and the time when the radio wave is received by the antenna 21a. The distance to the communication device MS is calculated.

  The positioning unit 21 calculates the latitude, longitude, altitude of the mobile communication device MS and the clock error in the control unit 11 by calculating the distance between at least four satellites, and displays the positioning result on the display unit 15. To display. Further, the display unit 15 is caused to display a portion including the obtained latitude and longitude positions in the map stored in the map storage unit (not shown).

  The infrared communication unit 31 communicates by emitting infrared rays from the light emitting unit 31a and infrared rays received by the light receiving unit 31b, and transmits positioning assistance information or receives positioning assistance information.

  The NFC communication unit 32 performs communication by the NFC method using radio waves transmitted and received by the antenna 32a, transmits positioning assistance information, or receives positioning assistance information. Note that the NFC communication unit 32 does not consume power when placed in a standby state, that is, in a state where it is detected that a radio wave has been received by the antenna 32a.

  Based on a predetermined key operation of the input unit 16, the domestic / overseas mode setting function 11-1 sets whether the mobile communication device MS is used in the main country or in other countries. Based on this setting, the channel used by the mobile communication network transmitting / receiving unit 13 is selected. In addition, the communication method used for communication with the base station (for example, the CDMA method or the GSM method), A frequency may be selected. Further, the domestic / overseas mode setting function 11-1 is not limited to setting whether or not to be used in other countries, and may set the country to be used based on a predetermined key operation of the input unit 16. good. Here, the country means an area that requires a change in the channel, communication method, and frequency described above for communication with the base station.

  The positioning auxiliary information update control function 11-2 updates and stores the positioning auxiliary information stored in the positioning auxiliary information storage unit 22 in a predetermined case. This update storage is performed by receiving positioning auxiliary information from the positioning auxiliary information server device SV via the mobile communication network transmitting / receiving unit 13, or via the infrared communication unit 31, the NFC communication unit 32, or the connector 33. This is performed by receiving positioning assistance information from the second mobile communication device MS-2.

  Next, the operation of each part of the positioning auxiliary information server device SV will be described with reference to FIGS. The wide area network communication unit 42 transmits the high frequency signal received from the hub of the wide area network WN to the wide area network transmitter / receiver 43. In addition, the high-frequency signal transmitted from the wide area communication network transceiver 43 is transmitted to the hub of the wide area network WN.

  The wide area network transmission / reception unit 43 amplifies, frequency converts and demodulates the high frequency signal transmitted from the wide area network communication unit 42, and transmits the demodulated control signal to the control unit 41. The positioning auxiliary information transmission request is transmitted to the positioning auxiliary information management unit 52. Furthermore, the control signal transmitted from the control unit 41 is transmitted to the wide area network communication unit 42. In addition, the positioning auxiliary information transmitted from the positioning auxiliary information management unit 52 is transmitted.

  The positioning unit 51 repeats positioning. This positioning operation is the same as the positioning operation of the positioning unit 21 except that the radio wave received by the antenna 51a is used, but is not necessarily the same. This is because the positioning unit 51 is required to obtain more accurate positioning and a correction value to be added to the positioning result, so that even if positioning is performed using radio waves transmitted from all captureable satellites. good. In addition, the necessity of the power consumption reduction of the positioning auxiliary information server device SV is low, and the necessity of performing the positioning of the positioning unit 51 in a short time is low.

  The positioning unit 51 should be added to the measured latitude, longitude, and altitude by referring to the latitude, longitude, and altitude of the position where the pre-stored positioning auxiliary information server SV is installed. Calculate the correction value. This correction value depends on, for example, weather conditions. Each time positioning is performed, information used for positioning included in the radio wave transmitted from the positioning satellite, such as satellite orbit information, clock error of the satellite, and information for identifying the satellite used for positioning Then, positioning auxiliary information in which the correction value is associated with the time at which positioning is performed is updated and stored in the positioning auxiliary information storage unit 53.

  When the positioning auxiliary information management unit 52 receives the positioning auxiliary information transmission request via the wide area communication network transmission / reception unit 43, the positioning auxiliary information management unit 52 transmits the positioning auxiliary information stored in the positioning auxiliary information storage unit 53 via the wide area network transmission / reception unit 43. To send.

  Here, further explanation will be added to the positioning assistance information. The positioning auxiliary information is information having the same configuration for both the information stored in the positioning auxiliary information storage unit 22 and the information stored in the positioning auxiliary information storage unit 53. The positioning assistance information is less useful for the mobile communication device MS as the distance between the position of the mobile communication device MS and the position where the positioning assistance information is obtained is larger.

  Next, the operation of updating and storing the positioning auxiliary information stored in the positioning auxiliary information storage unit 22 by the positioning auxiliary information update control function 11-2 of the mobile communication device MS having the above configuration will be described in detail. First, with reference to the flowchart shown in FIG. 4, the operation | movement which receives the positioning assistance information from the positioning assistance information server device SV, and updates and stores it is demonstrated.

  In the following four cases, the positioning auxiliary information update control function 11-2 starts an operation of receiving and updating the positioning auxiliary information from the positioning auxiliary information server device SV (step S101). The four cases are as follows. First, it is a case where a request from the positioning unit 21 is received. Second, the mobile communication device MS is powered on. Third, it is determined that the mobile communication device MS has moved from outside the service area of the mobile communication network to the service area based on the notification from the mobile communication network transmitting / receiving unit 13. Fourth, the setting is changed by the domestic / foreign mode setting function 11-1.

  In the second to fourth cases, there is a high possibility that the position of the mobile communication device MS has changed since the positioning auxiliary information was stored in the previous positioning auxiliary information storage unit 22, and the positioning auxiliary information is updated and stored. Is deemed appropriate. Note that the position of the mobile communication device MS can be approximated by the position of the base station received from the base station with which the mobile communication network communication unit 12 communicates. Further, it can be obtained by positioning by the positioning unit 21. Therefore, the positioning auxiliary information update control function 11-2 starts the above operation assuming that the position of the mobile communication device MS has changed when the position obtained by these methods has a predetermined change. Also good.

  Subsequently, the positioning auxiliary information update control function 11-2 requests the positioning auxiliary information server SV to transmit positioning auxiliary information via the mobile communication network transmission / reception unit 13 (step S102). In response to this request, it is determined whether or not the positioning auxiliary information transmitted from the positioning auxiliary information server device SV is received (step S103), and if received, the received positioning auxiliary information is used as the positioning auxiliary information storage unit 22. (Step S104), the positioning auxiliary information is received from the positioning auxiliary information server device SV, and the operation of updating and storing is terminated (step S105).

  When it is not received in step S103, the positioning operation information is received from the positioning assistance information server SV, and the operation is immediately terminated without updating and storing (step S105). If this is not received, it means that the mobile communication device MS is outside the service area of the mobile communication network, and the operation start of the positioning auxiliary information update control function 11-2 is the first, second, and first Case 4 is possible. However, even if the operation is completed without storing the positioning auxiliary information, the above operation is performed when it is determined that the mobile communication device MS has moved into the service area of the mobile communication network, and there is no problem. There is no.

  Next, with reference to the flowchart shown in FIG. 5, the operation of the positioning assistance information update control function 11-2 receiving and updating the positioning assistance information from the second mobile communication device MS-2 will be described. The positioning auxiliary information update control function 11-2 is configured so that the second mobile communication device MS is in accordance with a predetermined key operation of the input unit 16 and when a predetermined signal is received by the NFC communication unit 32 via the antenna 32a. -2 starts the operation of receiving and updating the positioning auxiliary information from step -2 (step S201).

  Here, when the operation is started in accordance with a predetermined key operation of the input unit 16, a key operation is performed in combination with whether it is received by the infrared communication unit 31, received by the NFC communication unit 32, or received through the connector 33. Specified by. Further, when a predetermined signal is received by the NFC system communication unit 32, it is considered that the NFC system communication unit 32 designates reception. In this case, the key operation of the input unit 16 of the mobile communication device MS is unnecessary, and the operability is excellent.

  Subsequently, the positioning auxiliary information update control function 11-2 controls the designated processing unit to establish a communication link with the second mobile communication device MS-2 or through the connector 33. A communication link with the second mobile communication device MS-2 is established (step S202), and the time in the positioning auxiliary information stored in the positioning auxiliary information storage unit 22 is transmitted via the link, and the second The time is received from the mobile communication device MS-2 (step S203). This time is the time in the positioning auxiliary information stored in the second mobile communication device MS-2.

  It is determined whether the time in the two positioning auxiliary information is new or old (step S204), and the time in the positioning auxiliary information stored in the positioning auxiliary information storage unit 22 is older (it is a past time). The auxiliary information update control function 11-2 receives the positioning auxiliary information from the second mobile communication device MS-2 via the link (step S205), and the received positioning auxiliary information is stored in the positioning auxiliary information storage unit 22. The update storage is performed (step S206), and the operation of receiving the positioning assistance information from the second mobile communication device MS-2 and updating the storage is ended (step S207).

  In step S204, when the time is newer (or more recent), the positioning auxiliary information update control function 11-2 stores the positioning auxiliary information stored in the positioning auxiliary information storage unit 22 via the link. The transmission to the second mobile communication device MS-2 is performed (step S208), and the operation for receiving and updating the positioning auxiliary information from the second mobile communication device MS-2 is ended (step S207).

  Obviously, the above operation not only updates and stores the positioning auxiliary information stored in the positioning auxiliary information storage unit 22, but also updates and stores the positioning auxiliary information stored in the second mobile communication device MS-2. Including. Therefore, the positioning auxiliary information stored in the second mobile communication device MS-2 may be updated and stored. That is, it is useful for both the user of the mobile communication device MS and the user of the second mobile communication device MS-2.

  In the operation of receiving and updating the positioning assistance information from the second mobile communication device MS-2 described above, before the start of this operation, the infrared communication unit 31 and the NFC system communication unit 32 do not supply any power. Excellent power consumption reduction without consumption. In this operation, the possibility that the communication is intercepted without any setting of confidentiality or an operation for performing communication while maintaining confidentiality can be ignored. That is, since the possibility of leakage of positioning assistance information and the possibility of leakage of positioning assistance information being communicated can be ignored, the confidentiality is excellent.

  The positioning auxiliary information update control function 11-2 is configured to perform communication when any communication by the infrared communication unit 31, any communication by the NFC communication unit 32, and any communication via the connector 33 are performed. In addition, the positioning auxiliary information may be received from the second mobile communication apparatus MS-2 described above and updated and stored.

  According to this operation, the positioning assistance information is automatically updated without the awareness of the user of the apparatus. The communication includes, for example, communication of address information stored in an address book (not shown), communication of schedule information stored in a schedule management unit (not shown), and game information by a game unit (not shown). Communication is optional and is not limited at all.

  In the above description, the second mobile communication device MS-2 is a device that performs the same operation with the same configuration as the mobile communication device MS, but is not limited thereto. It is an arbitrary device that stores positioning auxiliary information, has a function corresponding to the positioning auxiliary information update control function 11-2, and is connected to the mobile communication device MS via the short-range communication line LL, for example, a personal computer. Also good.

  In the above description, the mobile communication device MS receives the positioning assistance information from one positioning assistance information server device SV and updates and stores it. However, the present invention is not limited to this. When a plurality of positioning auxiliary information server devices SV are installed at geographically distant positions, the most useful positioning is obtained by requesting the positioning auxiliary information server device SV installed at a position closest to the mobile communication device MS. Auxiliary information can be received and updated and stored.

  The position of the mobile communication device MS can be approximated by the position of the base station received from the base station with which the mobile communication network communication unit 12 communicates, for example. Alternatively, it is obtained by positioning by the positioning unit 21. Each position of the plurality of positioning auxiliary information server devices SV is stored in, for example, an arbitrary positioning auxiliary information server device SV, and each position is answered in response to an inquiry from the mobile communication device MS.

  In the above description, the positioning assistance information server device SV stores the positioning assistance information obtained by the device itself, but is not limited thereto. For example, the antenna 51a and the positioning unit 51 are installed at a plurality of geographically separated positions, and positioning auxiliary information at each position is calculated. The positioning auxiliary information request from the mobile communication device MS is accompanied by the position of the mobile communication device MS, and the positioning auxiliary information server device SV transmits positioning auxiliary information obtained by positioning at a position closest to the position. You may do that. The position of the mobile communication device MS can be obtained by the method as described above.
