In addition, when the communication unit receives contact information including the contact information of the user of the other communication device from the other communication device, the control unit 101 and the storage unit 109, the contact information, It is an example of the memory | storage means which matches and memorize | stores the positional information corresponding to the time which received the said contact information acquired by the positional information acquisition means.

When the user B inputs an instruction to display the contact information to the communication device 100B, the control unit 101B reads the contact database 120B from the storage unit 109B, along with the name, phone number, e-mail address, address, and work place. The position information is displayed on the display unit 108.
In short, the control unit 101 and the display unit 108 read the contact information and the position information associated with the contact information from the storage unit, and display the contact information and the position information in association with each other. It is an example of a means.
The above is the operation of the present embodiment. When the contact information is transmitted from the communication device 100B to the communication device 100A, the communication device 100A and the communication device 100B in the description of the above operation are interchanged.

According to the present embodiment, the position information of the communication device when the communication device receives contact information from another communication device is displayed. The location information is effective as auxiliary information for remembering the contact partner.

In step B01, the control unit 101 determines whether or not to record position information based on permission information included in the contact information received from the communication device 100A. When the permission information is “1”, the position information is recorded (step B01: YES), and the process proceeds to step A03. If the permission information is “0”, the position information is not recorded (step B01: NO), and the process ends.
The processing after step A03 is the same as in the first embodiment.

  In this embodiment, the sender of the contact can determine in advance whether or not the location information can be stored. For example, if you do not want a third party to know the location you meet, you can specify that the storage of location information is not permitted by the permission information. Even if it is stolen, it is possible to prevent the third party from knowing the location of the meeting.

(3) Third Embodiment The third embodiment is a modification of the first embodiment. Here, differences of the third embodiment from the first embodiment will be described.
(3.1) Configuration FIG. 9 is a diagram showing the contents of the contact address database 122. In the present embodiment, a contact database 122 is stored in the storage unit 109 instead of the contact database 120 of the first embodiment.

  In the contact database 122, accuracy information is written in addition to a telephone number, an e-mail address, a name, an address, a work place, and position information. The accuracy information is information indicating the accuracy of the position information generated by the positioning device 400. For example, when generating location information including a prefecture name, a city name, a town name, a town name, a town block code, and a residence number, the accuracy information is “0”, and includes the prefecture name, city name, and town name. When generating location information that does not include a block code and house number, set the accuracy information to “1”, generate location information that includes the prefecture name and city name, and does not include the town name, block code, and house number. In the case of making it, accuracy information is set to “2”. When the communication device 100 transmits the contact information to another communication device 100, the communication device 100 transmits the contact information including the accuracy information.

(3.2) Operation The operation of this embodiment will be described with reference to FIG.
The processing contents of steps A01 and A02 are the same as those of the first embodiment, but the contact information transmitted from the communication device 100A in step A01 includes accuracy information as described above.
In step A03, the positioning information receiving unit 110B receives positioning information from the four positioning satellites 300.
In step A04, the positioning information receiving unit 110B supplies the received positioning information to the packet communication unit 102. In addition, the control unit 101B supplies the accuracy information included in the contact information to the packet communication unit 102B. The packet communication unit 102 transmits the received positioning information and accuracy information to the positioning device 400 via the mobile packet communication network 200.

In step A05, the control unit 401 calculates the latitude and longitude of the communication device 100B based on the positioning information received from the communication device 100B, extracts the residence display corresponding to the latitude and longitude from the position information database 420, and extracts it. The position information including the displayed residence is generated. When generating position information, the control unit 401 generates position information corresponding to accuracy information. For example, when the accuracy information is “0”, position information including a prefecture name, a city name, a town name, a town block code, and a residence number is generated. When the accuracy information is “1”, the prefecture If the location information includes the name, city name, and town name, but does not include the city code and residence number, and the accuracy information is “2”, it includes the prefecture name and city name. The position information not including the code and the house number is generated.
The processes after step A06 are the same as those in the first embodiment.
Note that the second embodiment and the third embodiment may be combined.

  According to the present embodiment, the sender of the contact address can determine in advance the accuracy of the position information stored in the communication device. For example, if the name of the city is sufficient, the information amount can be reduced by generating location information that does not include the city name, city code, and residence number.

(4) Modifications Modifications shown below may be combined with each other.
(4.1) Modification 1
The communication device 100 that is the transmission source of the contact information may acquire the position information from the positioning device 400. For example, before the communication device 100A transmits the contact information to the communication device 100B, the positioning information receiving unit 110A receives the positioning information and transmits the positioning information to the positioning device 400. When the position information is received from the positioning device 400, the position information is added to the contact information and transmitted to the communication device 100B. The communication device 100B writes the location information in the contact database 120B in association with the contact information.
If the communication device 100 that has received the contact information from the other communication device 100 does not include the positioning information receiving unit 110, or if the positioning information cannot be received due to some kind of failure, the position information is transmitted via the other communication device 100. May be obtained. For example, after the communication device 100B receives contact information from the communication device 100A, the communication device 100A requests location information from the communication device 100A that is the transmission source of the contact information, and the communication device 100A uses the positioning information receiving unit 110A. Positioning information is received, and this positioning information is transmitted to the positioning device 400. If position information is received from the positioning apparatus 400, this position information is transmitted to the communication apparatus 100B. The communication device 100B writes the location information in the contact database 120B in association with the contact information.
If the positioning information cannot be received due to some trouble, the positioning information may be transmitted to the positioning device 400 as soon as the positioning information is received.
According to these configurations, even when the communication device that receives the contact information cannot receive the positioning information, the communication device that receives the contact information can acquire the position information.

(4.2) Modification 2
When position information is displayed on the communication device 100, it may be displayed in the following manner. For example, when the control unit 101 displays a list of only position information corresponding to a specific city name on the display unit 108 and the user selects one of the displayed position information, the control unit 101 The contact information associated with the information may be read from the contact database 120 and displayed. According to this configuration, only contact information corresponding to a specific place can be acquired.
The positioning device 400 obtains the current position of the communication device 100, receives position information representing the current position from the positioning device 400, and the control unit 101 reads out contact information corresponding to the current position from the contact database 120. You may make it display. According to this configuration, only contact information corresponding to the current position of the communication device can be acquired.

(4.3) Modification 3
Instead of generating position information based on the positioning information obtained from the positioning satellite 300, the base station 210 acquires the identification information of the base station 210, transmits this identification information to the positioning device 400, and the positioning device 400 The position of the communication device 100 may be obtained based on the identification information. In this case, the accuracy of the position information is the size of the cell of the base station 210 (the range in which the radio waves of the base station 210 can reach).
The identification information of the location registration area to which the base station 210 belongs is acquired from the base station 210, this identification information is transmitted to the positioning device 400, and the positioning device 400 determines the position of the communication device 100 based on this identification information. May be. In this case, the accuracy of the position information is the size of the position registration area.
When the communication apparatus 100 includes a communication means using a wireless LAN (Local Area Network), identification information of the access point is acquired from an access point of the wireless LAN, and the identification information is transmitted to the positioning apparatus 400 to perform positioning. The device 400 may determine the position of the communication device 100 based on the identification information. In this case, the accuracy of the position information is the size of the range where the radio wave of the access point reaches.
When the communication apparatus 100 is located outside the communicable area of the base station 210 or the access point, the identification information may be acquired from the base station 210 or the access point when the communication apparatus 100 returns to the communicable area. .
According to these configurations, position information can be acquired even when the communication device does not have a function of receiving positioning information from a positioning satellite.

(4.4) Modification 4
In the first embodiment, the position information is acquired when the contact information is received. However, the position information may be acquired when another event occurs. For example, when the control unit 101 periodically acquires position information and receives contact information, the latest position information may be recorded. Alternatively, when the contact information is received from another partner within a certain period, for example, within 5 minutes after receiving the contact information from the first partner, the control unit 101 receives the contact information from the first partner. The position information acquired at this time may be recorded in association with the contact information of the other party. According to these structures, the process regarding acquisition of position information can be reduced.

(4.5) Modification 5
In the second embodiment, the necessity of recording location information is determined based on the permission information included in the contact information received from another communication device 100. However, the communication device 100 that receives the contact information receives the location information. The necessity of recording may be determined. For example, when contact information is received from another communication apparatus 100, the control unit 101 displays an operation element for selecting whether or not to record position information on the display unit 108, and the user records the position information. The control unit 101 may transmit the positioning information to the positioning device 400 when an instruction for ordering is input. According to this configuration, the user of the communication device on the receiving side of the contact information can decide whether or not to record the position information.
In the third embodiment, the position information with accuracy based on the accuracy information included in the contact information received from the other communication device 100 is generated. However, the accuracy information is stored in the storage unit 109 of the communication device 100 in advance. The position information may be generated by the positioning device 400 based on accuracy information stored in advance instead of the accuracy information included in the contact information. Alternatively, when contact information is received from another communication device 100, an operator for specifying the accuracy of the position information is displayed on the display unit 108, and the position information is displayed on the positioning device 400 with the accuracy specified by the user. You may make it produce | generate. According to these configurations, the user of the communication device on the contact information receiving side can determine the accuracy of the position information.

(4.6) Modification 6
In the first embodiment, the positional information including the residence display is generated, but the positional information including information other than the residential display may be generated. For example, the name of the building corresponding to the house display or the name of a famous building near the house display is stored in the position information database 420 in association with the latitude and longitude, and the control unit 101 stores the name of the building. Position information including may be generated. In addition, the control unit 101 generates position information including names of a plurality of neighboring buildings, transmits the position information to the communication device 100, causes the communication device 100 to display the names of the plurality of buildings on the display unit 108, and uses them. When the person selects any name, the control unit 101 may write only the selected name in the contact database 120 in association with the contact information. Further, position information representing a local name or country name may be generated. According to these configurations, it is possible to provide position information that is easy for the user to use.
The date and time when the communication device 100 receives the contact information, information representing the communication means used to receive the contact information, and the like may be written in the contact database 120 in association with the contact information.

(4.7) Modification 7
When the communication apparatus 100 has a function for recording a schedule, the contents of the recorded schedule may be displayed in association with contact information. For example, if a schedule table in which date / time and schedule are associated with each other is recorded, the schedule corresponding to the date / time when the control unit 101 receives contact information from another communication apparatus 100 is read from the schedule table. The schedule may be displayed on the display unit 108 together with the contact information. According to this configuration, it is possible to know in detail the situation when the contact information is received as compared with the case where only the position information is added to the contact information.

(4.8) Modification 8
In each embodiment, the contact information is exchanged by the short-range communication means using infrared rays. However, the short-range communication means using radio waves may be used, or the communication devices 100 may be paired with a communication cable. 1 may be used to exchange contact information. These are all included in the category of short-range communication means for performing communication between communication devices without going through a communication network. When exchanging contact information using the short-range communication means, the location information is equal to the information representing the place where the other party is met, so the place where the contact information is exchanged can be remembered.
Instead of performing short-range communication between the communication devices 100, contact information may be exchanged via a communication network such as the mobile packet communication network 200. For example, the contacts may be exchanged by e-mail via the mobile packet communication network 200. For example, when the communication device does not include short-distance communication means, it is conceivable that the electronic mail address of the person to be faced is communicated verbally and the contact information is exchanged with the electronic mail address. Also in this case, since the position information is equal to the information representing the place where the other party is met, the place where the contact information is exchanged can be remembered.

(4.9) Modification 9
In each embodiment, the contact information stored in advance in the contact database 120 is exchanged, but other information may be added to the contact information when exchanging the contact information. For example, the communication device 100 may include an imaging unit such as a digital camera, and the control unit 101 may add image data captured by the digital camera to the contact information and transmit the image data to another communication device 100. Alternatively, when contact information is received from another communication device 100, the control unit 101 may record the image data captured by the digital camera by adding it to the contact information.
The communication device 100 may be provided with recording means such as an IC (Integrated Circuit) recorder, and the control unit 101 may add the voice data recorded by the IC recorder to the contact information and transmit it to another communication device 100. Alternatively, when contact information is received from another communication apparatus 100, the control unit 101 may add and record voice data recorded by the IC recorder to the contact information.
The control unit 101 may add the character string input by the user using the operation unit 107 to the contact information and transmit it to the other communication device 100. Alternatively, when contact information is received from another communication device 100, the control unit 101 may add and record a character string input by the user using the operation unit 107 to the contact information.
According to these configurations, the situation when the contact information is exchanged can be known from an image, sound, or character string.

(4.10) Modification 10
Instead of generating position information by the positioning apparatus 400, the communication apparatus 100 may generate position information by providing the communication apparatus 100 with a position information generation function included in the positioning information.
Instead of providing the positioning device 400 in the mobile packet communication network 200, the positioning device 400 may be connected to a communication network outside the mobile packet communication network 200.
Instead of controlling the operation of the communication apparatus 100 by the CPU executing the OS and application programs, similar functions may be implemented by hardware circuits.
