[2. Configuration and function of the entire system of mobile phone device (mobile device)
Next, the configuration of the entire system of various mobile phone devices (hereinafter also simply referred to as “mobile phone”) including the mobile phone device (mobile device) 1 will be described.
A mobile phone (mobile device) is a portable phone using wireless communication. A relay point with a wired network called a base station and a mobile phone communicate wirelessly and can receive various communication services while moving.
Mobile phones are divided into generations according to the communication method with the base station, and mobile phones that have been marketed to date are roughly divided into three generations.

  The first generation mobile phone (1G) is a so-called “analog mobile phone” adopting an FDMA (Frequency Division Multiple Access) system. In the second generation mobile phone (2G), communication is digitized and TDMA (Time Division Multiple Access) is adopted, and PDC (Primary Domain Controller) and GSM (Global System) widely used in various European countries. for Mobile Communications). In addition, as a service called “2.5th generation (2.5G)”, which is one step ahead of the 2nd generation service, a cdmaOne service employing a CDMA (Code Division Multiple Access) method was started. In addition, cellular phone carriers in European countries have started a GPRS (General Packet Radio Service) service that enables high-speed communication of about 115 kbps on GSM networks, and the development of services that place emphasis on data communication rather than telephone calls has begun. It was.

  The 3rd generation mobile phone (3G) adopts the CDMA system, which enables conversations with less noise and interruptions, and enables high-speed communication that cannot be achieved with 2G, up to about 384 kbps even for data communication. Became. In the third generation mobile phone service, a broadband service using a mobile phone based on a wireless communication network with higher quality is provided.

Services using mobile phones tend to diversify.
The only service that was available in the first half of 1G and 2G was a pure call service such as making and receiving calls. However, in the second half of 2G and 2.5G, short message service (SMS) between mobile phone subscribers began.
The mobile phone has been rapidly becoming an Internet terminal, such as connecting to the Internet from a mobile phone to view websites and sending and receiving e-mails. The current mobile phone is a product that has become a more advanced internet terminal, and it supports mobile music and video distribution services, and some 3G services enable videophone functions. Continues to increase.

  In addition, mobile phones equipped with functions such as a digital camera function, application software execution function, or GPS function that are not directly related to telephone calls are also on the market. ) Is evolving into a device equipped with a function.

[2-1. base station〕
Next, the base station will be described.
This base station is a device at the end of the mobile phone network that directly communicates with the mobile phone. They are installed on telephone poles, building rooftops, telephone boxes, and subway platform ceilings.
Since the number of people who can make a call at one base station is limited, two or more base station facilities may be placed in the same place in a busy place such as a downtown area.

The range in which the mobile phone can communicate with the base station by radio waves is the so-called “call area”, and calls can only be made within this range.
In early PHS, when the user moved while talking, the radio wave of the base station in communication could not reach and the call was interrupted. In order to overcome this weakness, mobile phones and recent PHS have a “handover” function that switches the communication partner to the base station with the highest reception sensitivity as the terminal moves.
In a broad sense, it also includes a wireless LAN access point (AP).

[2-2. (Zone construction method)
Next, the zone construction method will be described.
In public mobile communications, it is generally necessary to cover a large service area and simultaneously accommodate a large number of subscribers. To achieve this within a limited frequency, the service area is divided into a number of zones (regions, cells). In general, a method is adopted in which each base station is installed in each divided zone, and the same frequency is reused in geographically distant zones to achieve effective use of the frequency.

  A method of covering a service area by dividing it into a plurality of zones in this way is called a small zone method or a cell method in contrast to a large zone method in which a single base station covers a wide service area. In the cell system, in addition to a method of configuring one zone using an omnidirectional antenna in one base station, a plurality of sector zones (sectors) are configured using a directional antenna in one base station. The method is also adopted. This has the advantage that the interference direction can be substantially limited to the directivity direction.

[2-3. (Multi-channel access method)
Next, the multi-channel access method will be described.
In order to reduce call loss and use radio frequencies more effectively, it is desirable to be able to use as many channels as possible without limiting the frequencies that can be used by the mobile device. A method of allowing each mobile station to commonly own a plurality of radio frequencies and allocating and using vacant channels at the time of arrival and departure is called a multi-channel access method. Currently, with the development of a frequency synthesizer using a PLL (Phase Locked Loop), it is possible to realize a mobile device capable of switching thousands of channels at a low cost.

[2-4. (Multiple access method)
Next, the multiple access method will be described.
Multiple access methods include FDMA (Frequency Division Multiple Access), TDMA (Time Division Multiple Access), and CDMA (Code Division Multiple Access).

[2-5. (Register location)
Next, location registration will be described.
Since it is inefficient to make a call from a base station nationwide to call one mobile device, the location of the mobile device is registered on the network side in a certain area unit (location registration area) and For incoming calls, a method of calling only within the area is used. For this reason, when the mobile device moves beyond the location registration area, it is necessary to perform location registration from the mobile device to the network side. This is done in the following procedure.

(1) The mobile device recognizes that the area has been exceeded by receiving the location registration broadcast from the base station through the common control channel.
(2) The mobile station issues a location registration request to the mobile switching center via the base station using the common control channel.
(3) The mobile communication switching center updates the location registration of the mobile device in the home memory station (location registration server) on the network side.
(4) The mobile communication switching center notifies the mobile device that the location registration has been accepted via the base station.

[2-6. Incoming connection)
Next, incoming connection will be described.
The mobile station normally receives the common control channel and waits for a paging signal for the mobile station itself. Connection control when a call is received from a general telephone to a mobile device is performed as follows.

(1) A line is connected from a calling general telephone to the nearest mobile communication switching center A in the mobile communication network through the general telephone network.
(2) The mobile communication switching center A makes an inquiry to the home memory station and knows the location registration area of the mobile device.
(3) The mobile communication switching center A connects a line to the mobile station up to the mobile communication switching center B in the area, and calls the mobile station from all base stations in the area.
(4) In response to the call, the mobile device returns a response to the mobile communication switching center A via the base station, and the base station where the mobile device exists on the network side is a special case.
(5) On the network side, a communication channel for the call is selected from unused communication channels, transmission from the base station side is started, and the mobile device is notified.
(6) The mobile station switches to the notified channel and establishes a communication channel, whereby the wireless line connection control is completed.

[2-7. (Outgoing connection)
Next, outgoing connection will be described.
A call from a mobile device to a general telephone is performed according to the following procedure.
(1) The mobile device issues a transmission request to the mobile communication switching center via the base station.
(2) On the network side, a communication channel for the call is selected from unused communication channels, transmission from the base station side is started, and the mobile device is notified.
(3) The mobile station switches to the notified channel and establishes a communication channel.
(4) The mobile communication switching center extends the line in the mobile communication network to the connection point with the nearest fixed telephone network of the other party's general telephone, enters the fixed network, and connects to the other party's general telephone through the fixed network.

[2-8. Handoff)
Next, handoff will be described.
When the mobile device moves beyond the zone during communication, it is necessary to switch the base station for communication to the base station in the destination zone in order to connect the communication. This switching control is called channel switching during communication or handoff.
There are several methods for detecting the zone shift of a mobile device. In the digital method adopting TDMA, the mobile device side uses a TDMA empty slot to measure and compare the reception level of signals from surrounding zones. The method is adopted.

After detecting the zone shift in the mobile device, handoff is performed according to the following procedure.
(1) Report to the network side that there is a candidate for the switching destination zone from the mobile device.
(2) On the network side, it is confirmed that there is an empty channel in the switching destination zone, and a channel to be allocated is selected from among them.
(3) The base station in the switching destination zone starts transmission of the channel and notifies the mobile device to switch to the channel via the communicating base station.
(4) The mobile device switches to the channel and establishes a communication channel with the base station in the switching destination zone.

[2-9. (Authentication function)
Next, the authentication function will be described.
In order to verify the legitimacy of the terminal, a cryptographic technique with increased confidentiality is used. A private encryption key is registered in the network and the terminal, and the network transmits a random number to the terminal. The terminal performs an operation using the random number and the encryption key, and returns the operation result to the network. The network verifies the validity of the terminal by comparing the result of the operation with the returned result. Only random numbers and calculation results are sent and received on the wireless section, ensuring safety. Authentication is performed at the time of outgoing call from the terminal, incoming call, location registration request, and handover request.

[2-10. Wireless LAN]
Next, the wireless LAN will be described.
A wireless LAN is a LAN that transmits and receives data by wireless communication. In particular, it often refers to a network composed of devices compliant with the IEEE 802.11 standards.
In an office with many layout changes, a lot of time and cost are spent each time the LAN cable is redrawn, but such a problem does not occur in the wireless LAN.
Compared to a wired LAN in which the 100 Mbps 100BASE-TX standard has permeated, the transmission speed is not as fast as about 11 Mbps (in the case of IEEE 802.11b).

[2-11. Internet
Next, the Internet will be described.
The Internet is a huge computer network that connects networks all over the world using a communication protocol TCP / IP (Transmission Control Protocol / Internet Protocol).
This Internet is a distributed network in which there is no computer that controls the whole, and is made up of server computers scattered throughout the world connected to each other and providing services little by little.

Most of the services and applications provided on the Internet (from WWW (World Wide Web), FTP (File Transfer Protocol), basic ones such as e-mail to advanced ones such as credit card payments) are mostly TCP / IP. A standardized protocol that does not depend on the model is used, and various computers can communicate over the Internet across models.
In order to participate in the Internet, it is necessary to connect to a network already participating in the Internet through a dedicated line. When connecting from a general household, it is necessary to make a contract with a provider called an Internet service provider that accepts communication from a public line (such as a telephone line, ISDN line, or ADSL line) and connects to the Internet.

[2-12. WWW]
Next, WWW will be described.
The WWW is a document system that is used as a standard on the Internet and Intranet. It is possible to describe the logical structure and appearance of a document in a language called HTML (HyperText Markup Language), and to embed data other than characters, such as images and sounds, and positions (hyperlinks) of other documents in the document. As an Internet standard document system, it has spread explosively since the mid-1990s, and a huge WWW network on a global scale has now been built. It is the most frequently used application on the Internet.

[2-13. hyperlink〕
Next, hyperlinks will be described.
The hyperlink is position information such as another document or an image embedded in the document. A system in which a plurality of documents and related objects such as images are associated using hyperlinks is called hypertext. WWW is a representative example of hypertext. When a document is displayed on a Web browser and a link location is clicked with a mouse, it jumps to an associated link destination.

[2-14. Hypertext)
Next, hypertext will be described.
Hypertext is one of document systems using a computer. It is a mechanism that allows multiple documents to be linked to each other by embedding position information (hyperlinks) of other documents at an arbitrary location in the document.
When a document is displayed using dedicated browsing software, the document can be displayed one after another by following links. There is also a system that can embed various information such as still images, moving images, audio, music, etc. in one document using the link function.
One of the hypertexts is WWW, which is a huge document system built on the Internet.

[3. Communication protocol used in mobile phone device 1]
Next, an example of a communication protocol used in the mobile phone device 1 will be described with reference to FIG.

First, the outgoing connection and disconnection sequence will be described.
As shown in FIG. 4 (a), the mobile phone device 1 that is a terminal on the transmission side transmits a call setup signal (SETUP) and a transmission radio state report signal to the base station after the off-hook and dialing. A call setting acceptance signal (CALL PROC) is received from the side. After performing the authentication procedure, the base station transmits a radio channel designation signal. The mobile phone device 1 on the caller side captures the designated channel and sets a wireless line. Next, a ringing signal (ALERT) is received from the base station, and a ringing tone (RBT) is sent to the handset. When there is a response from the incoming communication terminal device, a response signal (CONN) is transmitted from the base station to the mobile phone device 1 on the outgoing side. Next, a disconnection signal (DISC) is transmitted from the mobile phone device 1 on the transmission side to the base station. The base station transmits a release signal (REL) to the mobile phone device 1 on the transmission side, and the charging ends here. The mobile phone device 1 on the transmission side transmits a release completion signal (REL COMP) to the base station, and receives a radio channel disconnection signal from the base station. Finally, the mobile phone device 1 on the calling side releases the wireless channel used for communication and disconnects the wireless line.

Next, the incoming connection and disconnection sequence will be described.
As shown in FIG. 4B, when the mobile phone device 1 that is a terminal on the receiving side receives a call signal from the base station, it transmits an incoming radio state report signal and automatically responds to the signal. To the base station. In addition, the base station transmits a wireless channel designation signal to the mobile phone device 1 on the receiving side to set up a wireless line. After the wireless line is set up, a call setup signal (SETUP) is transmitted from the base station to the mobile phone device 1 on the receiving side, and the mobile phone device 1 on the receiving side generates a ringing tone (RGT) and then calls the base station. A signal (ALERT) is transmitted. A response signal (CONN) is transmitted to the base station by the off-hook of the mobile phone device 1 on the receiving side, communication (call) is started, and charging starts. Since the disconnection sequence is almost the same as the above-mentioned disconnection from the transmission side, the description thereof is omitted.

  In the above-described protocol, terminal identification information (telephone number, terminal number, ID number, machine number, mobile station number, mail address, URL, URI, etc.) and service identification information (phone number) Email address, URL, phone call, e-mail, internet access, data download, etc.). In addition, each device has a plurality of terminal identification information and service identification information of its own device or a partner device (stored in the storage unit of its own device), and by selecting and using them, a specific service can be identified as a specific terminal It is possible to enjoy various services such as using the information and charging the selected terminal identification information.

[4. Functions of mobile phone device 1]
Next, among the functions that the execution program stored in the ROM 3 of FIG. 1 built in the mobile phone device 1 causes the CPU 2 to execute, the characteristic functions provided in the mobile phone device 1 of this embodiment will be described below. . In order to realize the position information acquisition function (position information acquisition means), it is necessary to use the GPS means 20 of FIG.

[4-1. (Location information acquisition function)
Next, the position information acquisition function will be described.
The GPS (Global Positioning System) generally receives radio waves including various information from a plurality of artificial satellites (GPS satellites), and indicates the position on the earth where one is located from the difference in arrival time. It is a system that calculates information such as latitude and longitude. Information indicating the position is referred to as position information or position information data. The GPS satellite is equipped with a very accurate atomic clock of rubidium or cesium, and determines the position of the GPS receiver using the time when a signal generated based on the atomic clock reaches the GPS receiver.

  In a position confirmation system using GPS for realizing a position information acquisition function, it is common to determine the position of a GPS receiver using four GPS satellites. If a high-accuracy watch is installed and used together, the position can be measured with three GPS satellites. Also, radio waves from the base station may be used in combination. The radio wave transmitted by the GPS satellite is spread spectrum, and a signal is transmitted using a different spreading code for each GPS satellite.

FIG. 5 is a diagram illustrating a configuration example of a position confirmation system including the mobile phone device 1.
The mobile phone device 1 having a GPS receiver captures a satellite using a different spreading code for each GPS satellite while receiving a signal transmitted by the GPS satellite. This GPS receiver measures the position based on the arrival time of the signal received from each GPS satellite, and transmits the position information to the center station 102 through the base station 100 and the communication network 101. On the side of the center station 102 (actually, the internal communication terminal device), area information (address data, place name, area name, peripheral information, map data, location information where map data is stored, based on the position information, A URL or the like indicating a place where map data is stored is searched from the databases (DB) 102a and 102b in the storage unit.

  The location information transmitted from the mobile phone device 1 to the center station 102 includes location information (raw location information) that hardly processes information received from GPS satellites, or location information (calculated by the mobile phone device 1 side to some extent) Final position information) and intermediate position information (intermediate position information). There are various types of position information, but area information itself may be used. Note that it is not burdened to not process location information on the receiver side, but with recent advances in CPUs and peripheral LSIs, position calculation processing can be performed at high speed on the receiver side. A CPU and peripheral LSI may be incorporated in the mobile phone device 1.

Further, if the mobile phone device 1 performs all the position calculations and the mobile phone device 1 has a function corresponding to the database 102a, 102b of the center station 102 described above, the location is determined only on the mobile phone device 1 side. A confirmation system can be configured. In this case, since it is not necessary to download the map data from the center station 102 every time, the communication charge can be reduced. It goes without saying that the function sharing of which functions the mobile phone device 1 has can be changed as appropriate.
Further, the position can be measured by assuming that the base station 100 is a GPS satellite so that the position can be confirmed even indoors where the GPS satellite cannot be captured.

[4-2. (Location information transmission function)
Next, the position information transmission function (position information transmission means) will be described.
The mobile phone device 1 has a communication partner identification function and a position information transmission function in addition to a position information acquisition function and a wireless communication function (wireless communication means 12) for acquiring position information of the own device. The position information transmission function is a function of transmitting position information (or information related to position information) acquired using the GPS means 20 to the communication partner apparatus when communicating with a predetermined communication partner.

Specifically, the location information data is included in the call setup signal (SETUP) and transmitted to the communication partner device (in this example, the mobile phone device 103 in FIG. 5). Of course, the communication partner identification function is not essential, and may be transmitted to all partners. Since the position information includes errors depending on the state of measurement (when radio waves cannot be received from the satellite, etc.), the positioning level is displayed (for example, within 50 m, 100 m, 200 m, etc., and the number of symbols and marks) Display the positioning level). Further, one or more pieces of acquired position information and related information (date and time, positioning level, etc.) may be stored (history information).
When calling a predetermined telephone number, the cellular phone device 1 which is a calling side device (transmitting side device) uses the location information of the own device as a destination communication device (called side device, called side device, receiving side device). ).

  Based on the received location information, the mobile phone device 103 that is the counterpart communication device displays map information and location information that indicates the location of the mobile phone device 1 that is the counterpart communication device at a predetermined location of the map information. . Further, if the mobile phone device 103 also has a GPS function, it is possible to display its own location information together with the location information of the mobile phone device 1 that has transmitted the location information. In order to make the position information easy to recognize, a mark may be displayed on the map information instead of the position information itself (hereinafter, “position information” includes “position mark”). In this case, it is preferable to display a mark that can distinguish the opponent from the other person. Specifically, marks such as letters, numbers, alphabets, pictograms, pictures, diagrams, and figures can be considered.

  The map data is stored in advance in the memory units of the own device and the communication partner device, and this map data is used when normally displayed. Further, when necessary (when map data corresponding to position information or an area to be displayed is not stored in the memory unit, or when it is stored but old map data), the map data is transferred to another device (for example, FIG. 5 in the base station 100 or 104, a device connected to the base station 100 or 104, or the server device 40 in FIG. 3), and stored in the memory unit for display. Good.

  Further, the cellular phone device 1 may transmit the map data together with the position information. Furthermore, by exchanging position information with each other between the communication devices, the positions of the partner devices can be displayed on the display unit of their own devices. Furthermore, if both devices are equipped with a GPS function, the positions of the partner device and one's own device can be displayed on the display unit of one's own device. This is the same not only between two persons but also between many persons. Further, the mobile phone device 1 that is a calling side device can have the function of the mobile phone device 103 that is the called side device.

  In the cellular phone device 1, the position information transmission function includes a communication partner determination function for determining whether or not a predetermined communication partner to which position information is to be sent. As a specific example of the communication partner determination function, it may be possible to use a telephone directory function (identification information storage function) that stores identification information (partner identification information, terminal identification information) such as the telephone number or communication address of the other party. It is done. Taking a telephone number as an example, a telephone number for transmitting location information is registered in the telephone directory function. Specifically, a storage area corresponding to the phone number stored in the phone book function, that is, a location information transmission bit is prepared, and the location information transmission bit is activated for a phone number registered as a phone number to which location information is sent. Keep it.

  When a phone number with an active location information transmission bit is selected from the phone book function, or when a phone number is directly entered using the numeric keypad, the phone number is registered in the phone book function and is located. When the phone number check function that checks whether the information transmission bit is active determines that the entered phone number is registered in the phone book function and that the location information transmission bit is active For example, the position information acquired by the GPS means 20 is inserted into a communication protocol (for example, a call setup signal (SETUP)) and transmitted to the partner apparatus.

  The mobile phone device 103 that is the called device has a similar phone book function, and checks whether the identification information of the mobile phone device 1 received from the mobile phone device 1 is stored in the phone book function. If the position information transmission bit is further activated, the position information of the own apparatus (cellular phone apparatus 103) is transmitted to the cellular phone device 1 if it is activated.

  In addition to the telephone number, the other party identification information may be a mail address, an IP address, a URI, or the like. The position information is inserted into each protocol and transferred to the partner apparatus. Alternatively, instead of the communication partner determination function, the partner identification information is set (stored in the flash ROM 4) by selecting the communication partner from the telephone directory function, and the position information is transmitted to the set communication partner. Also good.

  In this way, during telephone communication or data communication, position information is transmitted to each other, and map data and its position are displayed based on the received position information. In addition, transmission / reception of location information and display of map data and location may be performed even during a telephone call or data communication. By doing so, it is possible to confirm the position of the user and the position of the opponent on the display unit.

  In addition, when dialing a so-called emergency telephone number represented by 110 or 119, the location information is transmitted regardless of whether the location information is set to be transmitted by the location information transmission function. You may do it. This is so-called automatic transmission of position information. The determination as to whether or not the dialing is an emergency call is made by comparing whether or not the telephone number input to the mobile phone device 1 by the operation input unit 10a is a predetermined telephone number stored in advance in the flash ROM 4. Do.

  Alternatively, when an emergency phone number is input or when it is determined that the phone number is an emergency phone number, a message as to whether or not to transmit position information may be displayed on the display unit 10b. In this case, if there is a positive input, the position information is transmitted. Alternatively, when there is an input of a telephone number or emergency telephone number and an input of a call instruction (so-called call button or pressing of the call button or an input corresponding thereto), a message asking whether to transmit location information is displayed. If there is an affirmative input, the position information may be transmitted. Further, when a predetermined button on the operation input unit 10a is pressed during a call or communication, the position information may be inserted into the control protocol and transmitted. Only when an emergency telephone number is connected, position information may be transmitted by pressing a predetermined button on the operation input unit 10a.

In addition, when a call is made to an emergency telephone number, the location information may be transmitted periodically (with a predetermined period) thereafter.
Further, an emergency button is provided on the operation input unit 10a of the mobile phone device 1, and when the button is operated, the location information of the own device is periodically transmitted to a predetermined communication device thereafter. Good.

The position information to be transmitted is the position information acquired by the position information acquisition function, and the position information described in other embodiments described later can be applied. Further, when the position information is the position information obtained by the GPS means 20, the method of transmitting the position information after receiving the calculation result of the position information in the external device takes time, so the data itself received from the satellite You may transmit directly, or you may transmit the positional information calculated based on the data received from the satellite.
The position information transmission function (position information transmission means) includes a mail function (mail means), a server connection function (server connection means), an FTP function (FTP means), an HTTP function (HTTP means), and the like.

For the mail function, so-called E-Mail using SMTP or POP3, or mail employing a unique protocol can be used. The position information is transmitted in the mail text or Subject column. The server connection function is a function of connecting the cellular phone device 1 to the server device 40 such as the so-called NTT Docomo i-mode (registered trademark), KDDI Ezweb (registered trademark), or the Internet. Data is exchanged between them, and position information is transmitted as data. The FTP function or the HTTP function uses FTP or HTTP as a protocol and includes position information in the data area of the protocol or transmits it as data itself.
As described above, since the position information is automatically transmitted, it is possible to specify the position of the communication apparatus that cannot normally specify the position.

[4-3. Map selection function (multi-person map information display function))
Next, the map selection function (map selection means) will be described.
As described above, when two or more pieces of position information are displayed on the display unit 10b of the mobile phone device 1 on the map data of a predetermined scale, one piece of position information (for example, the position of the mobile phone device 1) is displayed as map data. Even if it can be displayed within this area, it is outside the area of the map data displayed by the other position information (for example, the communication partner device), and both position information cannot be displayed simultaneously on the same map (map data). There are challenges. Therefore, in the mobile phone device 1 of this embodiment, a map that uses map data at a predetermined scale according to the positional relationship indicated by the plurality of position information so that a predetermined number of position information falls within the map data area. The mobile phone device 1 has a selection function.

Here, as a specific example of the map selection function, a case where two pieces of position information are displayed on a map will be described with reference to FIG.
FIG. 6 is a diagram for explaining processing when the mobile phone device 1 displays two pieces of position information on the map on the display unit 10b.

  A distance difference between the X direction and the Y direction of one position information and the other position information is set to x2 and y2, respectively, and the maximum horizontal distance x1 of the map data displayed on the display unit 10b of the mobile phone device 1 (own device) is When the maximum distance y1 in the vertical direction is set, and the map scale that satisfies “x1 ≧ x2 and y1 ≧ y2” is S, the map data is appropriately selected from map data having a scale larger than S. In this case, the scale S or a scale close thereto is usually selected, but the present invention is not limited to this. If one position information is to be displayed near the center of the map, map data having a scale more than twice that of S may be used.

In the example shown in FIG. 6, the map of s1 is initially displayed, and the position of one (mobile phone device 1) is displayed on the map ((a) of FIG. 6). Next, since “x2 ÷ x1> y2 ÷ y1”, a map with a scale of “s1 × x2 ÷ x1” is selected and displayed ((b) of FIG. 6). Next, in order to display the mobile phone device 1 in the center of the map, a map with a scale of “2 × s1 × x2 ÷ x1” is selected and displayed, and the mark of the mobile phone device 1 is displayed in the center of the map. Other devices and marks are also displayed at predetermined positions on the map ((c) of FIG. 6).
In addition, by applying the above processing example, a plurality of three or more devices can be arranged at predetermined positions on the map. Moreover, the map selection function which selects the map from which a reduced scale does not need to be limited to this, You may apply another well-known technique.

Further, as processing by the map selection function, processing for shifting original map data to be displayed according to a plurality of pieces of position information can be considered. This process will be described with reference to FIG.
FIG. 7 is a diagram for explaining another process when the mobile phone device 1 displays two pieces of position information on a map by the display unit 10b.

  One position is in the area of the map data, and the other position is outside the area in the left side direction of the map data. If the distance difference between one position and the right side of the map data is x5, and the distance difference between the other position and the left side of the map data is x6 ((a) of FIG. 7), if “x5−x6 ≧ 0”, Then, the map data moved by x6 to the left side is displayed ((b) of FIG. 7), and marks corresponding to the respective position information are displayed on the map. Since the other position is on the left side of the map as it is, if the map data is further shifted in the left side direction by “(x5−x6) / 2”, the distance from the side of each position is equally divided ( (C) of FIG. If applied to the vertical direction in the same manner, two pieces of position information can be displayed on the same map data area.

Furthermore, it goes without saying that the processing example in the case where there are two pieces of position information to be described, can be applied to the case where three or more pieces of position information are displayed. In this case, the map selection function may always display the position of the mobile phone device 1 on the map. It is also conceivable to give priority to terminal devices (for example, the order in which communication is started) and display them on a map.
In addition, when a plurality of pieces of position information are displayed on a map, not all position information may be displayed on the map. In that case, a mark (mark) indicating that it is outside the map area can be displayed on the map. Any mark may be used, but an arrow pointing from the mark position to the corresponding position is preferable. Further, information such as the name and identification information of the terminal device that cannot be displayed on the map and the number of terminal devices that cannot be displayed can be displayed on the display unit 10b of the mobile phone device 1 (own device). Moreover, you may display the distance information between terminal devices.

As a method of retransmitting position information (update of position information), a method of transmitting new position information to a partner apparatus when a movement of a predetermined distance is detected, and a method of periodically transmitting position information to a partner apparatus and so on.
In the above, the case where the control protocol carrying the position information is transmitted / received while performing data communication or a call has been described. However, the terminal device does not perform communication or call and only the control protocol (control information) is used for position. You may provide the GPS communication means which is a communication mode only for GPS which transmits / receives information sequentially.
According to this embodiment, the positions of a plurality of communication devices can be confirmed on the same screen.

[4-4. (Functions related to displaying map information)
Next, a function related to display of map information (hereinafter also simply referred to as “map information display function”) will be described.
The cellular phone device 1 is connected to a destination (place to be visited, place name of the desired location) or a target (desired or desired building, equipment such as XX department store, XX bank) by the operation input unit 10a. When the position information of (name) is input to the own apparatus, or the position information is retrieved from the place name or name and input to the own apparatus, the position information is transmitted to the base station 100 or the base station 100 by the position information transmission function. To the other side (or the communication line side). In addition, you may transmit the positional information on the own apparatus acquired by the GPS means 20. FIG.

The base station 100 or the base station 100 side (or the server device 40) analyzes the received position information using a map information selection function, selects map information of a predetermined area corresponding to the position information, and uses it as position information. Is sent back to the mobile phone device 1 of the transmission source.
The mobile phone device 1 that has received the map information displays the map information on the display unit 10b of the own device (or an externally connected display unit), and at the destination (or by the destination mark function of the own device). A mark indicating the location of the target object is displayed at a predetermined position in the map information. Further, the position information of the own apparatus is acquired by the GPS means 20, and a mark indicating the position of the own apparatus is displayed at a predetermined position of the map information by the own apparatus mark function (own apparatus mark means).

  The position information is usually expressed by latitude and longitude, but may be expressed by other expression methods (address information, telephone number, postal code, etc.). Further, in the case of normally used address information (XX prefecture XX city), a mobile phone device 1, an external device, or a base is provided with a location information conversion function (location information conversion means) for converting address data into location information. You may have a station. Further, an arbitrary place of the map information may be converted into position information or address information by specifying the input by the operation input unit 10a of the mobile phone device 1. The position information may be input from one or more words or words displayed in advance (may be displayed in a menu format such as a pop-up menu) or from the operation input unit 10a. Arbitrary phrases and words may be input. Further, a destination or destination object may be searched using free word search (keyword search), and the result may be used. The search engine may be used for the free word search, and the result may be acquired from the search engine to specify the position information. Further, position information centered on the gravity from the external device may be used. Further, the types of address information and position information need not be limited to those already described, and other known techniques can be applied. The phrases and search results used for the search are stored in the flash ROM 4 as a history. Then, since it is memorize | stored as a log | history, it can read, display later, and can be reused.

The destination mark function searches for position information on the map information that matches or approximates the position information of the destination or target object, and puts a predetermined mark indicating the position of the map information corresponding to the corresponding position information on the own device. It is displayed on the map data displayed on the display unit 10b.
The own apparatus mark function searches for position information on map information that matches or approximates the position information of the own apparatus, and displays a predetermined mark indicating the position of the map information corresponding to the corresponding position information on the display unit 10b of the own apparatus. Is displayed on the map data displayed on the screen.
The map information selection function selects map information including the location indicated by the position information from the flash ROM 4 that stores map information in advance. As a specific means for this selection, a currently known technique can be applied.

[4-5. (Functions related to storing map information)
Next, functions regarding storage of map information will be described. The mobile phone device 1 is assumed to include a plurality of storage units such as a memory card (IC card) and an HDD (not shown) in addition to the flash ROM 4 as a storage unit capable of storing map information.

  The cellular phone device 1 including the GPS means 20 having a GPS receiver also has a map data inspection function (map data inspection means), calculates position information based on radio waves received from GPS satellites, and the position information is It checks (investigates and searches) whether map data including the indicated position is stored in the storage unit of its own device. At this time, the storage unit (flash ROM 4 in this example) that is normally set (default setting) as the storage unit in which the map data is stored is first inspected, and if there is no corresponding map data, Inspect other storage units (memory cards, etc.) of the device itself. That is, each corresponding storage unit is inspected based on the priority order.

  If the map data is stored in the storage unit of the own device, the map data is displayed on the display unit 10b of the own device. On the other hand, if the map data is not stored in the storage unit of the own device, FIG. The position information is transmitted to the center station 102, the corresponding map data including the position information is downloaded to the own apparatus in the database 102a of the center station 102, and the map data is displayed on the display unit 10b.

At this time, the center station 102 searches the database 102a for the presence of the corresponding map data, and if there is no corresponding map data in the database 102a as a result of the inspection, the center station 102 searches the other database 102b. Then, the presence or absence of the corresponding map data is inspected, and if there is still no map data, the mobile phone device 1 is notified accordingly.
When receiving the notification, the cellular phone device 1 displays a message to that effect on the display unit 10b.

  Note that the cellular phone device 1 may delete the downloaded map data later, or it can be reused next time by storing it in the storage unit of its own device. Further, even when the map data is stored in the storage unit of the own device, if the map data is old, new map data may be downloaded from the database 102a or 102b of the center 102 station.

Here, a map data inspection function for inspecting whether or not the map data including the position indicated by the position information in the mobile phone device 1 is stored in the storage unit of the own device will be specifically described with reference to FIG. The map information is assumed to be composed of map data and metadata such as a file name of the map data. The position information is assumed to be composed of latitude information and longitude information. The acquired position information is assumed to be latitude 5 and longitude 5 (in Shinjuku 1-chome).
FIG. 8 is an explanatory diagram showing an example of the relationship between map data and position information (region).
The map data of Tokyo consists of 10 × 10 = 100 map data, and Shinjuku, which is one of the map data, further consists of 10 × 10 = 100 map data.

(0, 1000) (region information) means that latitude information is 0 and longitude information is 1000. The area can be represented by a plurality of pieces of position information (in this case, latitude information and longitude information). For example, when the area is a rectangle, the area can be represented by position information of four vertices. When the area is a square, it can be represented by position information of two vertices. Further, when the distance information of one side is determined in advance, the area can be represented by the position information of one vertex.
FIG. 8 (a) shows the map data of Tokyo and its area. If the area at the bottom left (0, 0, 100, 100) is Shinjuku, for example, the map data of Shinjuku and its area are shown. The area is as shown in FIG. 5B, and the map data can be enlarged and displayed. The black part in the figure indicates that there is no map data.

  Accordingly, when the mobile phone device 1 displays a wide area after acquiring the position information, the map data (level 1) of the entire Tokyo is displayed on the display unit 10b by the operation input of the operation input unit 10a according to the position information. In the case of displaying an area that is larger than that, the map data (level 2) of the entire Shinjuku is displayed on the display unit 10b by the operation input of the operation input unit 10a according to that, and further enlarged than that. When displaying an area, map data obtained by dividing Shinjuku (for example, Shinjuku 1-chome) (level 3) may be displayed by an operation input of the operation input unit 10a corresponding to the area.

FIG. 9 is a diagram showing an example of an information management table including position area information and map data file names corresponding thereto. This information management table is stored in the flash ROM 4.
Whether the mobile phone device 1 has position area information (corresponding position area information) including the position information in the information management table for the position information calculated and calculated based on the radio wave received from the GPS satellite. Inspect whether. If the corresponding position area information is in the information management table, the file name of the map data corresponding to the position area information is output.

Here, in FIG. 9, (0, 0, 100, 100), which is the area information of the file name: Shinjuku 20050620, 0, 0 is the latitude and longitude information of the lower left vertex of the square, and 100, 100 are respectively This is the latitude and longitude information of the top right vertex.
Now, considering that the acquired location information is latitude 5 and longitude 5 and the map data is displayed in the level 1 area, the mobile phone device 1 first sets the “level” for the management table of the entire file name: Japan 20050620. It is checked whether or not there is a map corresponding to latitude 5 and longitude 5 in 1 map data (47 prefectures such as Tokyo, Kanagawa, and Hokkaido).

  Since latitude 5 and longitude 5 correspond to position information in Tokyo, if there is map data for Tokyo, the file name of the map data (Tokyo 20050620) is output. The same applies when levels 2 and 3 are specified. Similarly, in the case of enlargement or reduction display in which level 2 or level 3 is instructed after level 1 is displayed, the map data is searched by searching the file. When the map data is vector data, it can be dealt with by enlarging or reducing the map data itself.

  In FIG. 9, the number in the number column represents link information between files. The date in the management table and the file name represent the update date and time of the map data. The old and new column is information indicating whether the map data is latest or old. The information in the memory area column indicates the location (memory address or the like) where map data corresponding to the file name is stored. It should be noted that the medium name (internal memory, internal HD, internal CD, external memory, etc.) in which the map data is stored may be stored.

The cellular phone device 1 also has a map data conversion function (map data conversion means) and a map data display function (map data display means).
The map data conversion function reads map data (stored in a format such as compressed data such as JPEG and JBIG, vector data, etc.) corresponding to the output file name from the storage unit and applies it to the display unit 10b. Convert to a data format (for example, bitmap data) and output.
The map data display function develops and stores the bitmap data in a display frame memory (video memory) 16 and reads the map data stored in the frame memory 16 and displays it on the display unit 10b.

On the other hand, the map data inspection function of the mobile phone device 1 outputs a signal indicating that it is not stored unless the position area information is in the information management table.
When receiving a signal indicating that map data is not stored, the location information transmission function of the cellular phone device 1 transmits the location information to the center station 102 via the base station 100 and the communication network 101. At this time, before transmission to the center station 102, in order to notify the user of "whether or not map data can be downloaded from the communication network", information to that effect is displayed on the display unit 10b, and there is an affirmative input. In this case, the operation of downloading from the communication network 101 may be continued.

The center station 102 searches the map data database 102a or 102b for the map data including the area indicated by the received position information, and transmits the corresponding map data to the mobile phone device 1. At this time, the center station 102 transmits map data in a data format (data format, compression method) that can be handled by the mobile phone device 1. The center station 102 acquires information in a data format that can be handled by the mobile phone device 1 by the initial negotiation of communication.
The map data conversion function of the mobile phone device 1 converts the received map data into bitmap data and outputs it.

The map data display function develops the bitmap data in the display frame memory 16, and reads the map data stored in the frame memory 16 and displays it on the display unit 10b.
Note that the cellular phone device 1 may delete the downloaded map data after it has been used, or may store it in the storage unit of its own device so that it can be used next time. At this time, the information management table is updated by adding a new map data file.

  Next, even if the corresponding position area information is in the information management table, if the map data corresponding to the position area information is old, a signal indicating that is output. After that, the same operation as when no map data is stored is performed. When storing the downloaded new map data in the storage unit, the old map data is deleted. The information management table is also updated with new and old information and changed information.

The cellular phone device 1 is also provided with a map data new / old judgment function (map data new / old judgment means), which judges whether the map data (map information) stored in the storage unit of the own device is old. . Several methods are conceivable as methods for the determination.
As a first method, the determination is made based on time stamp information (information indicating the latest date and time when the file is updated) added to the map data file. Specifically, the map data is compared with the date and time information to be used and the time stamp information, and if there is a predetermined time difference, it is determined that the data is old.

  As a second method, there is a method of adding information (old / old information, version information, etc.) indicating new / old for each map data file. This new / old information is used when a predetermined event occurs, such as when the communication device makes an inquiry to the center station 102 regularly or irregularly, or when the map data is updated regularly or from the center station 102. For example, it is conceivable to receive a notification of data change. The mobile phone device 1 updates the new and old information of the map data file based on this notification. Further, when the latest or new map data is downloaded, the downloaded map data may be replaced with old map data.

  Next, multiple map data files are gathered into one area (for example, a relatively large area such as Tokyo or Kanagawa Prefecture, a medium area such as a city or ward, or a town). Narrow area) may be supported. For example, when only the map data of Tokyo is stored in the storage unit of the mobile phone device 1, the mobile phone device 1 is used in Kanagawa Prefecture, and the map data of the location of the mobile phone device 1 is displayed. At this time, since the map data of Kanagawa Prefecture is stored in the storage unit of the mobile phone device 1, it is necessary to download the map data from the communication network 101. In this case, the map data of all areas in Kanagawa Prefecture, the map data of the area of the city, or only the map data of the town can be downloaded, so let the user choose which data to download. In addition, a message to that effect may be displayed on the display unit 10b. Alternatively, the selection may be made in units of files, not in units of regions.

  Whether only the data stored in the storage unit in the mobile phone device 1 is used as the location confirmation map data (memory mode), only the map data of the center station 102 is used (download mode), or As described above, whether to use both of them (hybrid mode) may be selectively set according to the operation input of the operation input unit 10a by the mode setting function (mode setting means) of the mobile phone device 1. .

Further, the cellular phone device 1 may include a map data history function (map data history means) so that the history of the map data displayed on the display unit 10b is stored in the storage unit and the history can be displayed. The history includes history information such as displayed date / time, file name, position information, data in the storage unit of the own device or information indicating downloaded data.
Further, each map data may be displayed with a history or a thumbnail image alone. In this case, when a history or thumbnail image is selected by an operation input of the operation input unit 10a, map data corresponding to the history or thumbnail image may be read from the storage unit and displayed on the display unit 10b.

  In the example of the function relating to the storage of the map information described above, the cellular phone device 1 uses the GPS means 20 to acquire the position information, but the GPS means 20 is not necessarily required. For example, when the position information is calculated by receiving radio waves from a plurality of base stations, the position information itself is, for example, the operation input unit 10a of the own apparatus, the external I / F unit 18, the wireless I / F unit 23, In some cases, it may be acquired from the communication network 101 side.

  The software for controlling the operation for handling the position information described above may be firmware created in a dedicated language. However, if importance is attached to versatility, it is better to create it in Java (registered trademark) language. This is often called a GPS app. This GPS application can be downloaded from the communication network 101 and installed. Further, when the version of the GPS application becomes old, it can be updated by downloading a data file used by the GPS application body or the GPS application from the communication network 101.

An example of the function relating to the storage of the map information described above can be expressed more generally. “If data related to the acquired information is in the storage unit of the mobile phone device 1, the data is used, but if there is no related data, , Receive related data from the server device 40 on the communication network 101.
Further, the map data downloaded based on the position information is stored in the flash ROM 4 or a memory dedicated to map data such as a memory card or a caching memory, and the position indicated by the next input position information and the previous position information are stored. When the distance to the indicated position is equal to or smaller than the predetermined distance, the map data stored before may be displayed without downloading new map data.

  In short, the technique described above downloads only map data that needs to be updated (including a case where there is no data and it is newly stored). Then, in order to minimize the update (reduce the amount of data to be downloaded), the map data that needs to be updated out of the map data necessary to display the map may be downloaded. That is, only the map data that needs to be updated is received from the server device 40 among the map data in the area based on the position information of the own device or the set position information, or the map data necessary for navigation.

[4-6. (Information acquisition function based on location information)
Next, an information acquisition function based on position information will be described.
As an information acquisition function based on position information, there are a function of acquiring information around the current location of the mobile phone device 1 and a function of acquiring information around a specified location (arbitrary location).
When a predetermined function is selected and executed by an input operation of the operation input unit 10a, the cellular phone device 1 transmits predetermined command information to the device on the base station 100 side or the server device 40. Hereinafter, the device on the base station 100 side and the server device 40 are collectively referred to as an external device.

When the external device receives the command information, the external device transmits predetermined information to the mobile phone device 1 based on the command information. For example, if the predetermined command information is a command (get command) that “receives information stored in a specified information storage location (for example, represented by a URL, URI, etc.)”, it is stored in that information storage location. Information is transmitted to the mobile phone device 1.
The mobile phone device 1 that has received the information displays predetermined information on the display unit 10b of the own device based on the information.

  The cellular phone device 1 selects and executes one command information by an input operation of the operation input unit 10a by the user based on the information displayed on the display unit 10b of the own device. At this time, one piece of information (URL, URI, etc.) based on the “command information” transmitted to the external device may be transmitted to another mobile phone device 103. Then, the other mobile phone device 103 that has received the information based on the “command information” receives the same information as the information received by the mobile phone device 1 from the external device by transmitting the command information to the external device. Therefore, even if the information received from the external device is large-capacity information, it is only necessary to receive information based on the “command information” itself, that is, information with a small capacity, from the mobile phone device 1.

In addition, when the mobile phone device 1 executes a function of “send location information of its own device to an external device and receive information based on the location information, or fixed information or menu information” When an operation that is selected and executed by the input operation of the input unit 10a is performed, first, the GPS unit 20 acquires the position information of the own device, and the position information, “information based on the position information, and other information” The command information “send information” is transmitted to the external device.
When the external device receives the position information and the command information, the external device transmits predetermined information to the mobile phone device 1 based on the information.
The mobile phone device 1 that has received the information displays predetermined information on the display unit 10b of the own device based on the information.

Instead of the position information of the mobile phone device 1, position information of a designated place (an arbitrary place designated by an instruction by an input operation) may be used.
The external device transmits map data, other information, or menu information to the mobile phone device 1 based on information (position information, date and time information, keyword information, search information, etc.) received from the mobile phone device 1. And repeat this.
Information provided by the external device to the mobile phone device 1 includes location information or date / time information, map information based on search information, weather forecast, traffic information, transit information for transportation, regional information, event information, category (or genre) ) Information (convenience store, bank, station, parking lot).

The menu information displayed by the mobile phone device 1 may be changed based on position information, date / time information, or search information. For example, “information on beaches” is displayed in summer, and “information on ski resorts” is displayed instead in winter.
Further, the location information is transmitted from the mobile phone device 1 to the external device, and the location indicated by the received location information is within a predetermined region (prefecture, city, town, local government, etc.) in the external device that has received the location information. If it is, information set in advance in association with the area is transmitted to the mobile phone device 1. At this time, if the received position information is the position information of the mobile phone device 1, special information (privilege information) is transmitted to the mobile phone device 1 as a different process.

  The cellular phone device 1 that has received the privilege information displays the information on the display unit 10b, and an input operation is performed on the operation input unit 10a by the user (operator) based on the information. For example, privilege information is music data (music information, ringtones, ringtones, ringtone data, etc.), games, software, shopping points, coupons, discount information, discounts on communication charges (free), etc. If so, the item selected by the input operation on the operation input unit 10a can be downloaded to the own device.

If the location information transmitted by the mobile phone device 1 is not the location information of the device itself but information input as arbitrary location information (other than the location information of the device itself), the external device transmits privilege information. However, for example, only the display data may be transmitted so that the information is actually displayed and cannot be downloaded. For this purpose, it is necessary to send information indicating whether the position information is the actual position information of the mobile phone device 1 or not to the external device.
Thus, for the purpose of attracting customers, a privilege can be given when the user of the mobile phone device 1 can reliably detect that he / she has actually visited the area.

[4-7. Information search function)
Next, the information search function will be described.
As an information search function, a function for searching and acquiring information around the current location where the mobile phone device 1 is (current location search function) and a method for searching and acquiring information around a specified location (arbitrary location) (periphery search) Function).

FIG. 10 is a flowchart illustrating an example of information search processing by the mobile phone device 1.
The cellular phone device 1 starts the processing routine of FIG. 10 according to a predetermined instruction by an input operation of the operation input unit 10a, and first performs the following processing in step S1. That is, within the predetermined area including the position information (or both) and the position (location) among the position information of the own device or the specified location (arbitrary location specified by the instruction by the input operation) Then, information (identification information, name, identification number, address information, area information, etc.) of the object whose position is desired to be transmitted is transmitted to the server device 40.

The server device 40 in this example is an information providing device constructed based on a storage unit that stores map information and destination (object) included in the map or address information of the destination. To do. In addition, similar information may be transmitted not to the server device 40 but to another external device on the base station 100 or center station 102 side, and the external device may perform the same processing as the server device 40 described later. Good. This is the same when each function to be described later is realized.
Based on the information received from the mobile phone device 1, the server device 40 transmits to the mobile phone device 1 map data and one or more location data (position information) corresponding to an object whose location is to be known.

  For example, in the place where the mobile phone device 1 is (or a place specified arbitrarily), if you want to look for a bank (for example, any bank that has an ATM because you want to withdraw money), it is obtained by the GPS means 20 Location information of the device and identification information (object information) representing the designated bank, that is, a category (for example, “bank” “cafe” “restaurant” “supermarket” “city bus” “convenience store” “toilet” “station” “Taxi”, “Department Store”, “Meals”, “French Cuisine”, “Italian”, “Shopping”, “Rest”, “Parking”, “Temple”, “Park”, etc.) are transmitted to the server device 40. The following processing is performed.

  That is, the map data including the received location information is selected from the storage unit of the own device, and further registered as a category of “bank”, and registered in the area of the map data (registered as included in the area) A plurality of target objects) from the database in the storage unit, and the map data and position information of one or more objects or information about the objects (name, address, contact information (phone number, e-mail address, URL) Etc.), the distance from the position based on the position information, etc.) is transmitted to the mobile phone device 1.

After transmitting the information to the server device 40 in step S1, the mobile phone device 1 waits for data reception from the server device 40 in step S2 and proceeds to step S3, and displays the received map data on the display unit 10b. In S4, a mark is displayed at the position of the own device or the designated place and the object on the map based on the position information of the own device or the designated place and the received position information of one or more objects (banks, etc.) or information about the object. To do.
11 and 12 are diagrams showing different display examples of a map on the display unit 10b of the mobile phone device 1 and marks indicating the positions of the own device and an object (a destination, etc.).

In addition, the server apparatus 40 may transmit the map data which displayed the mark which shows a position instead of transmitting the positional information on a target object.
When displaying the mark in step S4 of FIG. 10, the cellular phone device 1 uses highlighting (blinking display, display color different from other marks, etc.) to distinguish it from other marks on the map. ). A mark indicating a position is associated with position information (here, referred to as “URL”). When the mark is selected by an instruction by an operation input of the operation input unit 10a, the mark is displayed from the storage location indicated by the corresponding URL. Map information based on the position information can also be received. Further, when the corresponding URL is the home page of the object, the home page can be displayed. Furthermore, they may be displayed in a menu format and selected.

Further, not only the position information of the designated category but the position information of another category may be received and displayed. In this case, for example, the server device 40 may transmit the location information of the convenience store even if the bank is designated as the category.
The mobile phone device 1 may display information about the received object instead of displaying a map.
Alternatively, instead of displaying a map, a list of one or more received position information (name of object, related information, distance information, etc.) may be displayed. An example of the display is shown in FIG.

  At this time, the distance from the object may be displayed based on the position information of the device itself or the position information of an arbitrary place. The position information displayed in the list itself has link information (so-called URL), and when the position information is selected (clicked) by an instruction by the operation input of the operation input unit 10a and executed, the information of the link destination is displayed. Can be received and displayed. An example of the display is shown in FIG. Then, when one of the plurality of pieces of position information is selected by an instruction by an operation input of the operation input unit 10a and transmitted to the server device 40, the server device 40 transmits the received map data including the position information to the mobile phone device 1. Send to.

  The mobile phone device 1 that has received it displays a mark at a position based on the map data and position information and a position based on the position information of the object. An example of the display is shown in FIG. Then, when the cursor is moved to the mark by the operation input of the operation input unit 10a, information related to the object (including a telephone number, an address, position information, and a URL for displaying the home page of the object) is displayed. . When the mark is selected by an instruction by an operation input, the URL stored in the above-described information is transmitted to the server device 40, and the information stored therein is received from the server device 40.

  Alternatively, what is received from the server device 40 is not the position information itself, but may be information (such as a URL) that simply indicates position information or a location where map information corresponding to the position information is stored. Further, these “information indicating the storage location of predetermined information (URL, URI, etc.)” can be transmitted to other external devices (terminal devices) as text information at any time.

  Further, prior to the processing in step S1 in FIG. 1, a screen for inputting and specifying categories and subcategories as shown in FIG. 16 is displayed on the display unit 10b, and an instruction by operation input of the operation input unit 10a is displayed. It is also possible to specify the subcategory input together with the category input specification, and to narrow down the object by taking the logical product, for example. For example, when “convenience store” (category) and “sake” (subcategory) are input and transmitted, information on the location of a convenience store selling alcohol is sent from the server device 40.

Alternatively, in addition to the position information and the category, it is also possible to receive information based on the date and date information by inputting and transmitting date and date information.
Alternatively, input information (input information) such as position information, category, subcategory, date and date / time information may be stored in advance in a storage unit and displayed so as to be selected. At this time, menu display (pop-up menu display) may be performed like a pop-up menu. For example, as shown in FIG. 17, when “Restaurant”, “Bank”, and “Convenience store” are displayed as categories, and “Restaurant” is selected by an operation input by the operation input unit 10a, for example, as shown in FIG. “Italian”, “Ethnic”, and “French” are displayed as menus. That is, the display of the sub category type is changed according to the selected category type.

The object and its position information are stored in advance in a database in the storage unit of the server device 40. For example, GPS means is installed on the object, and the position information acquired by the GPS means is used using the communication network 101. May be periodically transmitted to the server device 40, and the server device 40 may update the database with the information. Then, even if the object moves (bus, taxi, train, mobile sales store, etc.), the position can be acquired.
In this way, when searching for a target object or a target location, it is possible to search for the location of the target object closest to the location where the user is.

[4-8. (Refine search function)
Next, the refinement search function will be described.
The narrowing-down search function is a function for specifying an object such as a place or a facility included in a predetermined area including the position indicated by the position information of the mobile phone device 1 and receiving information related thereto.
FIG. 19 is a flowchart showing an example of the narrowing search process by the mobile phone device 1.

  The cellular phone device 1 starts the processing routine of FIG. 19 according to a predetermined instruction by an input operation of the operation input unit 10a, and first performs the following processing in step S11. That is, one of the position information (or both) of the position information of the own apparatus or the position information of the designated place and the area information are transmitted to the server apparatus 40. For example, when the user is in the men's clothing department on the 5th floor (5th floor) of XX department store, the position information (including height information) is acquired by the GPS means 20, and the position information and area information are obtained from the server device 40. Send to.

  The server device 40 transmits map information corresponding to the received position information to the mobile phone device 1. Further, by using the received position information and area information, by searching for data stored in the database (storage unit) (data in which position information and location, facility, etc. are associated), the area or Get data from the database about the 5th floor of the XX department store and information about the men's clothing department from the database, and the information (XX department store, 5F, information about the men's clothing department, men's clothing department, etc.) Is transmitted to the mobile phone device 1. That is, the position information of all the objects (area objects) included in the predetermined area indicated by the area information or information regarding the area objects is transmitted.

After transmitting the information to the server device 40 in step S11, the cellular phone device 1 waits for data reception from the server device 40 in step S12, proceeds to step S13, and displays the received map information on the display unit 10b. In S14, a mark is displayed at the position of the own device or the designated place and the area object on the map based on the position information of the own device or the designated place and the received position information of the area object or the information on the area object. For example, as shown in FIG. 20, a three-dimensional map of a OO department store which is a three-dimensional map is displayed, and a position mark is displayed at the position on the fifth floor. At this time, information on the region object is also displayed in order from the position indicated by the transmitted position information.
Thus, the user can quickly and easily know information related to the place where the user is.

Also, after the server device 40 transmits information for confirming the position “Are you in a department store?” From the server device 40 and receives positive data from the mobile phone device 1, the above-described operation is performed. May be started. As a result, the mobile phone device 1 can make corrections, such as when there is an error in the acquired location information of the device itself.
On the server device 40 side, when it is determined that the mobile phone device 1 is in the XX department store based on the position information, the shopping point of the department store may be served. The points are transmitted and stored as electronic data in the mobile phone device 1 or the server device 40 that manages the points.

  As shown in FIG. 21, the predetermined area corresponding to the position information is determined as an area within a predetermined radius r around the position indicated by the position information, or an area having predetermined side lengths x and y. . The predetermined radius r or the predetermined side lengths x and y may be set or specified (transmitted together with the position information) from the mobile phone device 1, but if not set or specified, a default value (preset) May be used. An example of the storage contents of the storage unit (database) of the server device 40 corresponding to this case is shown in FIG.

[4-9. (Anything search function)
Next, the anything search function will be described.
Anything search function, such as a function to acquire location information of objects such as locations or facilities around the current location of the device (search for anything in the current location), or a function to acquire location information of objects around the specified location (neighboring Search anything).

FIG. 23 is a flowchart showing an example of anything search processing by the mobile phone device 1.
The cellular phone device 1 starts the processing routine of FIG. 23 according to a predetermined instruction by an input operation of the operation input unit 10a, and first performs the following processing in step S21. That is, one of the position information (or both) of the position information of the own apparatus or the position information of the designated place is transmitted to the server apparatus 40.

  The server device 40 transmits map data and information in a predetermined area set in advance to the mobile phone device 1 based on the position information received from the mobile phone device 1. The information in the predetermined area includes related information (position data, name, address, contact information (phone number, phone number, location, facility, etc.) in the predetermined area corresponding to the position information received from the mobile phone device 1. Email address, URL), detailed information, and other related information). Note that event information (information updated regularly or randomly) performed in the area based on the received position information may also be transmitted to the mobile phone device 1.

  After transmitting the information to the server device 40 in step S21, the cellular phone device 1 waits for data reception from the server device 40 in step S22, proceeds to step S23, and displays the received map data on the display unit 10b. In S4, a mark is displayed at the position of the own device or the designated place and the object in the predetermined area on the map based on the positional information of the own device or the designated place and the received related information on the object in the predetermined area.

  In addition, by designating an arbitrary position (place) on the map displayed on the display unit 10b, for example, a position surrounded by a broken line in FIG. 24A by an instruction by an operation input of the operation input unit 10a, Corresponding position information, for example, information shown in FIG. 24B can be acquired from the server device 40. In this case, the coordinates of the designated position on the map (map data) are converted into position information (using the position information conversion function), and the converted position information is used as position information to be transmitted to the server device 40. As a specific example of the position information conversion function, a conversion expression for converting position information (for example, latitude / longitude information) from the coordinates of a specified position on the map is prepared, and conversion is performed based on the expression. Alternatively, a method of storing the coordinates of the designated position on the map and the position information associated therewith in the storage unit as table information and retrieving the position information from the storage unit based on the coordinates of the designated position is also conceivable ( Table means).

[4-10. (Keyword, location information, time information linked advertising function)
Next, a linked advertisement function for keywords, position information, and time information will be described.
The advertiser has a problem of efficiently providing advertisement information to the user.
Therefore, in the mobile phone device 1 (the side where the advertisement is provided), a predetermined keyword (including selecting and inputting a category) is input to search for certain information, and the server device 40 (here, the search server). In the case of transmission to a device, an information providing server device, etc.), there is a method of receiving and displaying information (for example, advertisement information, link information) stored in advance corresponding to the keyword from the server device 40.

  Also, instead of (or in addition to) this keyword, location information (there are two types of location information (local location information and destination location information), or location information of the device itself) Use information (information such as time, date, day of the week, etc.). The two types of position information may be distinguished according to the format (expression format, etc.) of the position information. For example, if it is latitude / longitude information, it is determined that the position information of the device itself, and if it is address information, the position information is arbitrary or selected and specified. The advertisement information is a graphic advertisement such as a banner advertisement, a text-only advertisement, an image advertisement, a sound advertisement, and a video advertisement, and may include embedded information such as a link, meta information, and machine executable instructions.

  Specifically, for example, a certain area is divided into a plurality of areas, and predetermined information is associated with each of the plurality of areas and stored in the storage unit of the server device 40. When the location information is received from the mobile phone device 1, the information corresponding to the area including the location information is read from the storage unit and transmitted to the mobile phone device 1. The communication device that has received the information displays it on the display unit 10b. When a plurality of pieces of information associated with the area are registered, the information is displayed based on a predetermined priority order. The priority order may be determined according to price information (price information, budget information) for which the advertiser has bid for the condition. Further, it may be displayed in the order from the closest position of the mobile phone device 1. That is, the display order is determined based on at least one piece of information of the price information of the information and the position information of the mobile phone device 1.

For example, in the case where Tokyo is divided into 23 areas, an example of a combination of three pieces of information including a keyword, position information, and time information will be described with reference to FIG.
FIG. 25 is a diagram showing another example of the stored contents of the storage unit of the server device 40 of FIG.
If the location information received from the mobile phone device 1 is included in the area of Shinjuku, the received keyword is a restaurant, and the received time is 12:00, the server device 40 Information on the cafeteria (store name, address, ad text, link information, other related information, etc.) is transmitted. If the received time is 18:00, the information about the xx bar, the restaurant, and the restaurant is transmitted to the mobile phone device 1 and displayed on the display unit 10b in that order. Information to be displayed may be associated with one or more arbitrary combinations of keywords, position information, and time information. In particular, when the position information is the actual position information of the mobile phone device 1, displaying the advertisement information based on the time information has a great effect as an advertisement because the mobile phone device 1 is actually in the place.

  There is also a method in which advertisement information is not associated with a pre-delimited area. That is, the server device 40 has position information included in a predetermined area (for example, an area within a radius of 100 m) including the position information received from the mobile phone device 1 and is stored in its own storage unit. The information of the store or the object that is predetermined to display the information of the store or the object is transmitted to the mobile phone device 1. At this time, the map information of the area including the position information received from the mobile phone device 1 may be transmitted to the mobile phone device 1 together with the advertisement information. And the mobile telephone apparatus 1 which received advertisement information and map information displays the received advertisement information and map information on the display part 10b. As a display method, a method of displaying advertisement information superimposed on the displayed map information ((a) of FIG. 26), or an area for displaying map information and an area for displaying advertisement information are displayed on the display screen. There is a method of displaying separately ((b) of FIG. 26).

  Registration of advertisement information in the server device 40 can be performed by an advertiser via a network using a client device (a communication device such as a PC, a telephone, and a mobile phone). The advertiser registers the area information, category (keyword), time, advertisement information (advertisement title, advertisement content, etc.), advertisement price (budget), cost per click, address information, etc. in the server device 40. The address information is converted into position information such as latitude and longitude and stored in the server device 40. In addition, when the position of the client device used by the advertiser moves (for example, mobile sales), the position information acquisition function connected to the client device or the client device periodically acquires the position information. The location information can be registered in the server device 40, and the location information can be updated periodically by the advertiser.

Further, the mobile phone device 1 may display the received advertisement information together with the display of the search result on the same screen.
Here, the information search by the keyword, the position information, and the time information by the mobile phone device 1 and the process of the linked advertisement will be described with reference to FIG.
FIG. 27 is a flowchart illustrating an example of information retrieval and linked advertisement processing by the mobile phone device 1 using keywords, position information, and time information.

The cellular phone device 1 starts the processing routine of FIG. 27 according to a predetermined instruction by the input operation of the operation input unit 10a, and first performs the following processing in step S31. That is, the position information of the own device or the designated place, the keyword of the object whose position is to be known, and the time information are transmitted to the server device 40.
Based on each information received from the mobile phone device 1, the server device 40 receives the map data, one or more location information corresponding to the object whose position is to be known, information about the object, and corresponding advertisement information. Send to.

  After transmitting the information to the server device 40 in step S31, the cellular phone device 1 waits for data reception from the server device 40 in step S32, proceeds to step S33, and displays the received map data on the display unit 10b. After displaying the mark on the position of the own device or the designated place and the object on the map based on the position information of the own device or the designated place in S34 and the received position information of one or more objects or the information on the object, the step In S35, the corresponding advertisement information is displayed.

  The server device 40 may transmit advertisement information previously associated with the movement mode to the mobile phone device 1 based on the movement mode (walking, bicycle, car, train, etc.) of the mobile phone device 1. Or you may make it transmit the advertisement information matched based on the conditions which combined the movement mode, position information, and time information.

Further, the mobile phone device 1 transmits advertisement information to the mobile phone device 1 based on the direction of movement of the mobile phone device 1 (estimates the moving direction based on a plurality of location information of the mobile phone device 1) and the location information of the mobile phone device 1. You may make it do. That is, the advertisement information registered in the area based on the position away from the position of the mobile phone device 1 by a predetermined distance in the moving direction is displayed.
Furthermore, advertisement information may be selected and transmitted based on the terminal identification information of the mobile phone device 1. The advertisement information is selected based on past history information.
It is also possible to include the advertiser's position information in the advertisement information, set the position information as a destination, and execute the navigation function.

In addition, when the advertisement information described above is received, a communication fee is usually charged according to the amount of data. However, if the communication fee charged for the download is made free, the number of accesses can be predicted to increase. That is, a message indicating that the download (data reception) fee is free is displayed together with display information for selecting the advertisement information. Then, even if the data is downloaded, charging is not performed.
The advertisement information described above is not limited to information related to advertisements, but can be applied to any information.

[4-11. (Route search function for public transportation)
Next, the route search function of public transportation will be described.
The cellular phone device 1 searches for (searches) a route from a departure place to a destination (arrival place) based on route information such as timetable information and fare information of public transportation such as trains, airplanes, and buses ( The distance is the shortest, the earliest arrives, the lowest fare, etc.) and can be displayed on the display unit 10b.

The departure place is set based on the position information acquired by the position information acquisition function. For example, a list of stations, bus stops, airports, etc. close to the acquired position information is displayed (distance may also be displayed), and then one departure point is selected and set by an instruction by an input operation of the operation input unit 10a. Further, a station, a bus stop, an airport, or the like specified by the above-described narrowing search function may be set.
The destination (object) is set by searching with the above-described destination search function (information search function, narrowing search function, anything search function).

  A departure date and time is set, and a display for determining the earliest route to the destination based on the timetable information is performed. In addition, the arrival date and time is set, and the route from the latest departure location is obtained and displayed based on the timetable information. Further, a route for arriving at the destination with the cheapest fare is obtained and displayed based on the fare information. Alternatively, a plurality of destinations may be set, and the patrol route (the earliest arrival, the cheapest fare, etc.) may be obtained. In any case described above, the second and subsequent routes may be obtained and displayed.

In addition, when a transit point is set, a route passing through the transit point is obtained. When a non-passage line is set, a route that does not pass through the route is obtained.
In addition, by selecting information on the displayed transit point (station, etc.) and waypoints along the route, or by specifying an arbitrary position on the map, the location information of that point can be acquired, and the surrounding search function, etc. Can be used for

[4-12. (Navigation function)
Next, the navigation function will be described.
The navigation function can be set to the current location or delegation by arbitrarily setting the destination (or the location information searched by the peripheral search or current location search, or the location information transmitted by the partner device may be set as the destination). It is a function to perform navigation (road guidance) from the point.

  When the mobile phone device 1 first sets a destination and obtains the current location of the device according to an instruction by an input operation of the operation input unit 10a, a route (also referred to as a route from the current location to the destination, a route, or a route) is set. I do. The route is set according to the moving means such as walking, car, bus, train, car, etc., and the optimum route for the means is selected.

For example, for walking, based on the map information (metadata associated with the map information), the route with the shortest walking distance, the route with the least number of turns, the route using the road with the sidewalk, etc. A route corresponding to the user's preference information (selected by menu display) such as the combination is obtained.
In the case of a car, the route is searched based on the traffic jam information acquired from the server device 40 (external device). Further, based on the map information (map data and meta information), the route is determined so as to pass through as large a road as possible or a road with good scenery. Also, a route with few right or left turns is obtained.

  When the route is set, the map information is received from the server device 40 and displayed on the display unit 10b. At this time, the position of the device (start position) and the position of the destination (goal position) are displayed on the map, but the technology for displaying the own position and the position of the other party between the communication terminals described above (multi-person Map information display function) can be applied. In addition, line information (for example, a red thick line) indicating a route is drawn on the map. In addition, the distance to the destination or the remaining distance, the remaining arrival time, the arrival time, the map scale information (scale display), the direction display mark, the direction of turning at the intersection, date and time information, warning information, etc. are also displayed and updated accordingly. . Normally, two-dimensional map information is displayed, but switching may be made so that it is displayed on three-dimensional map information (map information drawn in three dimensions).

  When navigation is started, the GPS device 20 periodically acquires the position of its own device, and based on the position information and route information (departure location, arrival location information, information about the turning position, route width information, etc.) Various actions to guide to the destination (update of the position display of the device, guidance by voice or display (turn right at the next intersection (turning corner), deviate route, etc.), notify when approaching the destination Etc.).

  Note that the map information to be displayed based on the position information of the moving own device may also be displayed so as to move. At this time, the own apparatus mark indicating the position of the own apparatus is not moved from a certain position. In addition, when the route deviates from the route, the route may be reset from the position to the destination. Further, during the navigation, the “periphery search function”, the “current location search function” or other functions may be executed, and may be restarted after the function is completed. Furthermore, navigation may be performed by setting a plurality of destinations. In this case, the destination may be guided first to the nearest (or farthest) destination from the starting point (start position), or the order may be arbitrarily set.

  Further, it is possible to confirm the navigation in advance by performing a simulation without actually performing the navigation based on the position information. That is, instead of acquiring position information, the position of the own apparatus is moved at a predetermined speed based on the set route, and various operations for guiding to the destination described above are virtually performed (simulation). Thus, the same operation as the actual navigation is performed except that the acquired position information of the own device is not used.

  Furthermore, the navigation performed actually can be stored in the storage unit as a file and reproduced. For this purpose, the information set by navigation, the position information of the own apparatus acquired by the position information acquisition function and the related information are stored, and the navigation is operated based on the stored information when the information is reproduced. In practice, the navigation simulation function is operated on the basis of the position information and the interval information (difference of the acquired time) obtained from the position information.

Furthermore, the simulation operation may be fast-forwarded by simulating the time. The file can be sent to another device and played on that device.
The position information can be acquired not only based on the GPS means 20 but also based on radio waves from a plurality of base stations (position acquisition function by the base station), or a self-propelled part (equipped with an electronic compass and a speed sensor, The direction of the apparatus is acquired, the speed of the own apparatus is acquired by the speed sensor, and the position is acquired based on the result). Based on the output and the output of the GPS means 20, the own apparatus You may acquire a position.

[4-13. (Location information notification function)
Next, the position information notification function will be described.
When the mobile phone device 1 having the GPS means 20 and the position information transmission function receives predetermined command information (information for instructing to transmit the position information), the position information transmission function is acquired by the GPS means 20. The position information and the related information are returned to the communication device such as the mobile phone device that transmitted the command information (returned to the other party identification information received from the other party). In addition, you may make it send to another predetermined communication apparatus. When transmitting the command information, the position information of the own apparatus may be transmitted at the same time.

Functions (means) for receiving predetermined command information include a telephone function, a mail function (e-mail, short message, C-mail, etc.), an FTP function, and an HTTP function.
In the telephone function, a telephone is used as the partner communication apparatus, and when the mobile telephone apparatus 1 makes a call from the telephone, the mobile telephone apparatus 1 receives an incoming call and a communication path is set. In this case, command information including a predetermined DTMF signal is transmitted from the telephone, and the cellular phone device 1 performs the subsequent operation by detecting the DTMF signal.

In the mail function, the mail body or Subject including data corresponding to command information is received. Alternatively, a mail containing command information is received in the mail protocol.
In the FTP function and the HTTP function, the protocol or data including predetermined command information or the command information as data itself is received.
There are a method of replying automatically when the cellular phone device 1 receives command information, and a method of replying when an operation for agreeing to reply is performed on the operation input unit 10a.
Other known techniques can be applied instead of the telephone function, mail function, FTP function, and HTTP function.

Further, when the cellular phone device 1 receives predetermined command information, the use of the IC tag means 21 is prohibited or the use of the IC tag means 21 is canceled by a predetermined operation input of the operation input unit 10a. It is possible to prohibit or cancel the prohibition.
Further, the cellular phone device 1 provided with the GPS unit 20 is based on a predetermined condition, the position information acquired by the GPS unit 20, information related to the position information (time when the condition is established, time when the position information is acquired, The time when the predetermined information is transmitted, the date and time, or the information stored in advance (information notifying that a condition such as a message, a fixed sentence, or information indicating that the predetermined condition is satisfied) is established) It is also possible to transmit to a predetermined communication device (selected and set from pre-stored partner identification information) by the information transmission function.

  Furthermore, the mobile phone device 1 is provided with a position information log function (position information log means) for storing the position information acquired by the GPS means 20 and information related to the position information in the storage unit based on predetermined conditions. Is also possible. Alternatively, in the case of a predetermined condition, it is also possible to perform notification (sound by a speaker or buzzer, light emission by a light emitting device such as an LED, vibration by a vibrator, display of a message, etc.) by a notification function (notification means) of the device itself. .

  The predetermined conditions include a case where the IC tag means 21 provided in the mobile phone device 1 is used, a case where a predetermined time interval is reached, a case where a predetermined date, time, and time are reached. When command information, predetermined communication or mail is received, when the strength of the radio wave from the base station 100 changes (or when the base station notifies that the strength of the radio wave from the device has changed), A combination of predetermined conditions such as a case where the radio wave of the base station has not arrived (cannot be received) has arrived (can be received) can be considered.

  Another predetermined condition is the output of the position area determination function (position area determination means). The position area determination function determines whether or not the position information acquired by the GPS means 20 periodically or at a preset time has entered or exited a predetermined area of the preset position information. . As a method (method) for representing the predetermined area, an area having a predetermined radius centered on the position information, a square or rectangular area having a predetermined size centered on the position information, and the like are conceivable. It is determined whether or not the position information acquired by the GPS means 20 is included in the range information (range information) expressed in this way, or whether it is out of the range. The output of the position area determination function, that is, information indicating the inside or outside of the area is used as a predetermined condition.

  Whether or not the user has entered the area can be determined by judging that the position immediately before it is outside the area and that the current position is within the area, that is, moving from outside the area into the area. Good ((b) of FIG. 28). Whether or not the region has been exited may be determined by determining that the immediately preceding position is within the region and that the current position is outside the region, that is, moving from within the region to outside the region ( (A) of FIG. When entering and exiting from one area, the opposite may be the case.

  Further, a plurality of position information is set, and a plurality of settings (position information (area information) set in advance, information indicating an area based on the position information (for example, position information and the center) are set for each position information. (Expressed by the radius, etc.), position information acquisition start time, setting whether to notify when entering or exiting that area, setting of area notification function ON / OFF, etc. .

  Furthermore, when a plurality of position information is set, when passing through the plurality of regions (FIG. 29), or when reciprocating through the plurality of regions (FIG. 30), one exits the other region and It is also possible to set a combination such as when entering the area. The setting may be set using the operation input unit 10a of the mobile phone device 1 that informs the location information, or the partner terminal device that informs the location information (or a terminal that is permitted to be remotely set up (remote setup in advance). It may be set remotely (remote setting function).

[4-14. (Location information recording function)
Next, the position information recording function will be described.
The position information recording function periodically acquires position information, stores the result in a storage unit, and displays the result.
When using the location information recording function, the cellular phone device 1 can arbitrarily set location information acquisition conditions such as an interval for acquiring location information, date and time, or time according to an instruction by an operation input of the operation input unit 10a. Note that an operation for periodically acquiring position information may be started by an instruction to start position information acquisition by an operation input, and an operation for periodically acquiring position information may be ended by an instruction to end position information acquisition.

  When a certain condition is satisfied, the position information acquisition condition may be changed. For example, the position information acquisition condition is changed when the acquired position information enters or exits a preset area. Specifically, when the position information acquisition interval is set to one hour, when the acquired position information enters a predetermined area, the position information acquisition interval may be changed to 10 minutes.

When the log information is displayed on the display unit 10b by the position information log function, the mobile phone device 1 displays map data, and an animation function for sequentially displaying the position of the own device based on the position information on the map data. You may have.
The position information log function acquires position information using the GPS means 20 every time a predetermined condition is satisfied, and stores it in a storage unit as a log (history). The stored logs can be collectively transmitted to other communication devices. Or it can also be displayed on the display unit 10b of its own device.

The cellular phone device 1 has a position information log function and a radio clock function (radio clock means) described later, and the position information log function logs the position information acquired by the GPS means 20 and the time information acquired by the radio clock function. Can also be stored in the storage unit. Thereby, an accurate time can be recorded.
In addition, the mobile phone device 1 that receives the information that the condition is satisfied can store a history (communication date and time, received information, etc.) regarding the received communication.

[4-15. (Emergency location notification function)
Next, the emergency location notification function will be described.
FIG. 31 is a flowchart illustrating an example of an emergency position notification process performed by the mobile phone device 1.
The cellular phone device 1 starts the processing routine of FIG. 31 at a predetermined timing. First, in step S41, the mobile phone device 1 acquires its own location information by the location information acquisition function. In step S42, the mobile phone device 1 moves based on the location information. In step S43, based on the calculation result, the movement mode of the own device (moving on foot, bicycle, car, bus, train, airplane, etc.) is detected (predicted judgment), and the detection is performed in step S44. Notification processing is performed according to the result.
To do.

  Specifically, when the prediction determination start is instructed by the input operation of the operation input unit 10a, or when a signal including a start command is received from an external device (another communication device), the position information at a predetermined time interval. The position information of the device is acquired by the acquisition function, and the movement speed is measured (detected) based on the distance between the positions represented by the position information and a predetermined interval time, and the movement speed and the speed and movement stored in advance are measured. Based on the correspondence between the modes, the movement mode (movement state, movement means) of the own apparatus is predicted and determined. For example, when the data table indicating the correspondence between the movement speed and the movement mode as shown in FIG. 32 is stored and held in the storage unit, if the measured movement measure degree is 30 to 80 km / h, the movement means “ It can be judged as "car".

When the moving means is “car” (preliminarily set to notify when the vehicle is determined to be a car), the fact is notified to a predetermined destination by e-mail. By doing so, it is possible to know the state of the user who has the mobile phone device 1. In addition, when a child is taken away by car, this can also be detected.
In addition, when entering the area (call area) of a base station other than the preset base station, for example, when the location is registered in a base station other than the set base station, the base station that has determined it (or The external device) or the device itself may send a mail notification to a predetermined destination (FIG. 33).

Further, instead of the prediction using the position information acquisition function, the movement mode of the own device may be predicted based on the output pattern of the acceleration sensor of the own device.
Alternatively, since the mobile phone device 1 includes the photographing unit 14 (camera unit), when it is determined that it is an emergency (when the output of the acceleration sensor is a predetermined pattern, when the moving speed of the own device is a predetermined speed, When an emergency button or power-off button on the operation input unit 10a is pressed, or when the output of the acceleration sensor becomes a predetermined output, etc., the subject is automatically photographed at predetermined time intervals. It is also conceivable to transmit an image to a predetermined communication device.

  In this case, the cellular phone device 1 includes a clock function (clock means), a photographing function (camera means), and a transmission function (transmission means), each of which can apply a currently known technique. A predetermined communication address for transmitting to a predetermined time interval or a predetermined communication device can be set in advance. Further, instead of the predetermined time interval, an image may be taken and transmitted at one or more predetermined times. Alternatively, it is not always necessary to transmit an image every time shooting is performed, and the image may be transmitted when the amount of the image reaches a predetermined amount (a predetermined number of images, a total amount of data of the predetermined image). Good. Further, when a power adapter is connected to the mobile phone device 1, shooting and image transmission operations may be performed. Therefore, if the power adapter is not connected, shooting is not automatically performed. This is to prevent a battery shortage due to the fact that a considerable amount of power consumption may be required when shooting. The mobile phone device 1 with a camera can also solve the problem of being used as a monitor.

[4-16. Approach notification function)
Next, the approach notification function will be described.
For example, when the mobile phone device 1 is connected to the first external device and the second external device via a communication line (communication network), the location information based on the location of the mobile device 1 is stored in the first external device. When the position information storage control function (position information storage control means) to be stored in the storage unit and the position information stored in the storage unit of the first external device satisfy (satisfy) a predetermined condition, the first external A receiving function (receiving means) that receives (acquires) a notification to that effect from the device or the second external device. The first external device and the second external device may be the same device. The first external device and the second external device include a control unit including a CPU, a ROM, and a RAM, and a storage unit (nonvolatile storage unit) such as an HDD. A program executed by the CPU is stored and held in a ROM or a storage unit.

FIG. 34 is a flowchart showing an example of approach notification processing by the mobile phone device 1.
The mobile phone device 1 sets the use of the approach notification function according to an instruction by an input operation of the operation input unit 10a, and then periodically starts the processing routine of FIG. 34. First, based on the position of the own device in step S51. The location information is stored in the storage unit of the first external device, and in step S52, a notification that the location information satisfies a predetermined condition is waited, and the notification is received from the first external device or the second external device. In step S53, the contents of the notification are displayed on the display unit 10b. Note that the notification can also be output as voice by the speaker unit 11b.

Here, the location information is information stored and registered in the storage unit (home memory) of the first external device (management device) on the base station side for the location registration of the mobile phone device 1. 1 identification information and information of a base station (a base station in an area where the mobile phone device 1 is located) subject to location registration (for example, identification information for distinguishing base stations such as base station A and base station B) Etc.).
When the mobile phone device 1 uses (uses) the approach notification function, the mobile phone device 1 uses the corresponding instruction by the operation input of the operation input unit 10a to identify the target device's own device identification information and the condition of the base station set in advance as a condition. Information (may be a plurality of base stations), when the condition matches or partially matches (when the location information of the mobile phone device 1 satisfies a predetermined condition) The identification information of the target mobile phone device 1) is stored in the storage unit of the first external device on the base station side.

  Thereafter, the first external device monitors or acquires location information updated based on the location registration operation of the target mobile phone device 1, and this may be preset identification information of the mobile phone device 1. For example, when the position information matches or partially matches the position information set (stored) in advance, this is notified directly or to the second external device (other Notification by e-mail via the base station side). Specifically, the notification is made when the base station in which the identification information of the set communication device as the notification destination is registered is included in one or more preset base stations.

When it is determined that the distance between the two communication devices (including the mobile phone device 1) or the positional relationship between the communication devices has become close (approached) to some extent, this is notified to the own device or the other device. You may notify.
As a specific example, terminal identification information (identification number, telephone number, serial number, manufacturing number, address, etc.) of the own device and the partner communication terminal device is registered in advance on the base station side, and each device is currently connected to the communication. When the same base station (registered location) is the same (when entering the same base station area), or when the base stations with which each device is currently communicating are adjacent to each other When the relationship between base stations that are communicating (or registered for location) (information corresponding to the distance between base stations) satisfies a predetermined condition, from the device on the base station side that detects it That is notified to each communication device (or predetermined information is transmitted).

  Notification conditions (when communicating with the same base station, when communicating with neighboring base stations in the communication area, etc., when the relationship between communicating base stations satisfies a predetermined condition) and the effectiveness of the function Invalidity can be set from each communication device. The target of determining whether or not the distance is close is substituted by the relationship with the base station, not the actual distance between devices, but may be determined by measuring the actual distance.

  Each communication device that has received the above notification acquires the location information of its own device by the GPS means of its own device, transmits the location information to the counterpart device, and on the map information based on the received location information of the counterpart device. Displays the position of the device and its own device. Then, if the location information of the own device is continuously transmitted to the counterpart device thereafter (if the transmission of the location information is continued), the location of the counterpart device and the own device is displayed on the display unit of the own device almost in real time. Can do. And if the navigation function mentioned above is applied to this, a navigation can be performed between communication apparatuses, moving each other.

Moreover, the case where the position information acquired by the base station is used without using the position information acquired by the GPS means is also conceivable. This is to notify each communication device when the position information of the communication device registered in advance becomes a predetermined condition in the device (management device) on the base station side. The predetermined condition is that an area based on one position information (within a circle with a predetermined radius) and a position based on the other position information is included (included) in the area, or the areas overlap each other. In such a case, the distance between the positions may be a predetermined distance (or a predetermined distance or less).
Alternatively, it may be determined whether a predetermined condition is met based on the mutual position information on each communication device side, not on the base station side.
Further, the present invention can be applied not only between two parties but also in three or more communication apparatuses.

[4-17. (Security function using location information)
Next, a security function using location information will be described.
FIG. 35 is a flowchart showing an example of security processing using position information by the mobile phone device 1.

  The mobile phone device 1 starts the processing routine of FIG. 35 periodically after setting the use of the security function using the position information according to the instruction by the input operation of the operation input unit 10a. First, in step S61, the mobile phone device 1 The position information based on the position is stored in the storage unit of the first external device, and in step S62, a notification that the position information satisfies a predetermined condition is waited, and the notification is sent to the first external device or the second external device. If received from an external device, the operation of the own device is locked (prohibited) so that the operation of the own device cannot be performed in step S63. At this time, you may display that. Alternatively, it may be displayed that the position information satisfies a predetermined condition.

  For example, when the current position of the own device enters or exits a predetermined area, the operation of the device is locked so that the own device cannot be operated. Alternatively, functions that are set in advance as functions that are locked (prevent the use of predetermined functions) (for example, functions that require security such as telephone functions, functions related to electronic money, or functions related to payment, electronic commuter pass functions Alternatively, the electronic ticket function) may be locked.

Here, as the technique relating to the determination of whether or not it is within a predetermined area, the above-described technique (a technique using base station position registration information, GPS position information, or the like) can be used.
It should be noted that when entering (exiting) a predetermined area and being locked, when exiting (entering) the predetermined area, the lock may be released (automatically).
A plurality of predetermined areas can be set. You can also set whether to lock when entering or locking when exiting. It is also possible to combine a plurality of areas and patterns of entering and exiting.

[4-18. (Presence function using location information)
Next, a presence function using position information will be described.
FIG. 36 is a flowchart illustrating an example of presence processing using position information by the mobile phone device 1.
The mobile phone device 1 periodically sets the presence function using the location information in accordance with an instruction by the input operation of the operation input unit 10a, and then periodically starts the processing routine of FIG. 36, and first acquires the location information in step S71. The position information of the own device is acquired by the function.

  Next, in step S72, state information (presence function status information) of the own device is assigned based on the position information, and from another mobile phone device (which may be another communication device) set in advance in step S73. Waiting for the reception of the command information for obtaining the status information, and receiving the command information, in step S74, the status information of the own device assigned earlier is transmitted to the command information transmission source.

  Specifically, for example, predetermined position information (home, company position information) is stored and registered in advance in the storage unit of the own apparatus, and the position information of the own apparatus acquired by the position information acquisition function is the home position information. Status information “at home” if you are in a certain area, including “working” status information if you are in the company's location area, or “going out” if you are not at home or office Is assigned to each status information. Further, the above-described “movement mode” can be used as status information.

  Then, the terminal identification information of other mobile phone devices (terminal devices) that are allowed to acquire the status information is stored in advance in the storage unit, and the command information (command information) for acquiring the status information of the presence function When the terminal identification information is received from another mobile phone device, if the terminal identification information is the previously stored terminal identification information, status information is transmitted to the mobile phone device. Of course, status information may be transmitted even if the mobile phone device is not stored. Further, the status information may be transmitted without receiving the above-described command information.

[4-19. (Application download function)
Next, the application download function will be described.
FIG. 37 is a flowchart illustrating an example of application download processing by the mobile phone device 1.

  Each function described above is premised on being stored in a storage unit built in the mobile phone device 1 in advance, but when a predetermined function is selected and executed, the function is executed. Necessary application software (programs) can be downloaded from the server device 40 and operated. In this case, it is only necessary to store the minimum software (for example, a web browser) for downloading the application in the storage unit of the mobile phone device 1.

When the mobile phone device 1 performs use setting of the application download function in accordance with an instruction by the input operation of the operation input unit 10a, the processing routine of FIG. 37 is started, and first, operation guidance is displayed on the operation input unit 10a in step S81.
Then, in step S82, an instruction for selecting a function by an input operation of the operation input unit 10a is awaited. When the selection of the function is instructed by pressing an icon (button) of any function on the operation guidance, in step S83. The designated function is selected, and an icon of the selected function is displayed on the display unit 10b in step S84.
In step S85, an icon is designated (pressed). When the icon is designated and execution is designated, a corresponding process is performed in step S86.

  For example, when an instruction to select a general navigation function composed of a plurality of functions including a map information display function, a peripheral search function, and a navigation function is instructed, the general navigation function is selected, and the corresponding execution application is shown in FIG. As described above, icons of the three functions are displayed on the display unit 10b.
