Each component described below may be configured by hardware, may be configured by a software program, or may be configured by a combination of these hardware and software.

[User input section]
The user input unit 32 is a key operation unit provided in the mobile phone terminal of the present embodiment, and has a function of acquiring information input from the user.

[Location information acquisition unit]
The location information acquisition unit 30 is, for example, GPS information indicating latitude and longitude obtained from a GPS satellite, base station information (base station ID) obtained from a mobile phone base station, and access when connected to a network such as the Internet or an intranet. The IP address information and the like possessed by the point or a device connected to a certain network device are acquired as position information. That is, in the embodiment of the present invention, the position information is information that can specify an installation location of a certain device, for example, in addition to information indicating the absolute position on the map such as latitude and longitude information of the GPS information. For example, fixed IP address information assigned to a certain network device whose installation location is determined, or a base station assigned to each base station whose installation location is determined in the mobile phone system Information (base station ID) and the like are also included. In other words, the position information in the present embodiment does not necessarily need to be information representing an absolute position such as latitude and longitude information, and the installation of the network device to which the IP address is assigned, such as a fixed IP address. Information that can be used to specify a location, or information that can be used to specify an installation location of a base station to which the base station information is assigned, such as a base station ID, may be used. Further, in the present embodiment, the place specified by the position information is not limited to a place represented by a certain place name or area name, for example, but a certain building or facility itself, or a room in the building or facility, You can also list floors. For example, when location information such as GPS information, base station information, or IP address information is added to a received message, which will be described later, the location information acquisition unit 30 displays the location information added to the message. It is also possible to obtain.

  The acquisition of the position information in the position information acquisition unit 30 is set in advance, for example, when a position information acquisition instruction is input from the user through the user input unit 32 or when a preset position information acquisition time comes. It is executed at regular time intervals when event information of a schedule to be described later is input (schedule creation), when a message is transmitted or received, which is described later, or when an incoming or outgoing call is made. In any of these cases, the acquisition of the position information is set in advance by the user or initially set in the mobile phone terminal, for example.

[Location information creation / update section]
The location information creation / update unit 1 is the location information acquired by the location information acquisition unit 30, that is, for example, any one of the GPS information, base station information (base station ID), IP address information, or their information The location information table 2 in the message management database (DB) 20 is created and updated using some (two or all) information. Further, the location information creation / update unit 1 creates and updates the location name table 5 formed in the common database 21 using the location name information input from the user through the user input unit 32.

  That is, for example, when position information that is not registered in the position information table 2 is acquired by the position information acquisition unit 30, the position information creation update unit 1 stores the position information in the position information table. For example, when location name information not registered in the location name table 5 is input by the user through the user input unit 32, the location name information is stored in the location name table 5. Register new. The location information creation / update unit 1 receives, for example, location name information corresponding to the location information from the user through the user input unit 32 when the location information acquisition unit 30 acquires the location information. In this case, the position information table 2 and the place name table 5 are created and updated so that the position information and the place name information are associated with each other. In addition, when the location name information is input from the user via the user input unit 32 with respect to the location information already registered in the location information table 2, the location information creation / update unit 1 The location information table 2 and the location name table 5 are created and updated so as to associate the name information. Similarly, the location information creation / update unit 1 receives an instruction to associate the location information acquired in the location information acquisition unit 30 with the location name information already registered in the location name table 5. When input from the user through the unit 32, the location information table 2 and the location name table 5 are created and updated so that the location name information and the location information are associated with each other. On the other hand, when the position information and the place name information are already associated, the position information creating / updating unit 1 receives an instruction from the user through the user input unit 32 to change the association. Then, the location information table 2 and the location name table 5 are created and updated so as to change the correspondence between them. The location information and the location name information may be associated not only when one location name information is associated with one location information but also with a plurality of location name information associated with one location information. Or conversely, it is possible to associate a plurality of pieces of position information with one place name information.

[Event information creation / update department]
For example, when a schedule input from a user through the user input unit 32 or schedule data through communication or the like is input, the event information creation / update unit 3 uses the event information of the input schedule, The schedule management event information table 4 in 22 is created and updated. Further, the event information creation / update unit 3 receives, for example, location name information when a schedule is input from the user through the user input unit 32, or location name information is included in schedule data by communication or the like. Using the location name information, the location name table 5 in the common database 21 is created and updated.

  That is, for example, when new event information that is not registered in the schedule management event information table 4 is input, the event information creation / update unit 3 converts the event information into the schedule management event information table 4. In addition, for example, when the place name information not registered in the place name table 5 is included in the schedule, the place name information is newly registered in the place name table 5. Then, the event information creation / update unit 3 creates and updates the schedule management event information table 4 and the location name table 5 so as to associate the event information with the location name information. Further, the event information creation / update unit 3 receives new location name information for event information already registered in the schedule management event information table 4 or has already been registered in the location name table 5. When new event information is input for the location name information, the schedule management event information table 4 and the location name table 5 are created and updated so that the event information and location name information are associated with each other. . On the other hand, when the event information and the place name information are already associated with each other, the event information creating / updating unit 3 receives an instruction from the user through the user input unit 32 to change the association. First, the schedule management event information table 4 and the location name table 5 are created and updated so as to change their correspondence. The association between event information and place name information is not limited to the case where one place name information is associated with one event information, but a plurality of place name information may be associated with one event information. Or conversely, a plurality of event information can be associated with one place name information.

[Location information table, location name table, schedule management event information table]
