When the telephone number is uniquely associated and registered, the destination can be set. Even if the phone number stored in the external location database is a phone number of a mobile phone or an IP phone, the mobile phone can be used as long as information that can identify location information such as the owner of the phone and the address of the contractor is stored The location information can be specified by searching the point database from the telephone number such as.

  In addition, when the input telephone number is not registered as data, the navigation device disclosed in Patent Document 2 searches for an area indicated by the area code of the telephone number, and a map code (registered trademark) including the area. ) Detect the upper area and detect the three-digit code indicating that area. By inputting the fourth and subsequent digits of the map code of the point to be set as the destination point, the point search is performed assuming that the map code of the point is input.

  When the navigation device N requests the mobile terminal device T to acquire position information as described above, the mobile terminal device T is in a standby state and communicates with other devices such as the navigation device N. Must be ready to start. Therefore, when the navigation device N requests the mobile terminal device T to acquire position information, the navigation device N causes the output means 15 (display unit) to put the mobile terminal device T possessed by that fact and the user in a standby state. It is preferable to display a message to be requested.

  Hereinafter, the operation procedure of the navigation device N and the mobile terminal device T according to the present invention will be described with reference to flowcharts. 4 is a flowchart showing a processing procedure at the time of setting a point by inputting a telephone number in the navigation device N, FIG. 5 is a flowchart showing a processing procedure of the mobile terminal device T, and FIG. 6 is a position from the mobile terminal device T to the phone number. It is a flowchart which shows the process sequence of the navigation apparatus N which acquired information. Also, in the following explanation, the destination setting will be described as an example, but it is not always necessary to set the destination. The present invention can also be applied to.

  Referring to the flowchart shown in FIG. 4, in navigation device N, control means 10 determines whether or not a destination setting has been input (step S41). If there is an input of the destination (YES in step S41), it is determined whether or not the setting is made by inputting a telephone number (step S42).

  If there is no destination setting input (NO in step S41), if the information input for setting is not a telephone number (NO in step S42), the destination is set according to information other than the input telephone number. After the route search and the route guidance are executed (step S46), it is determined whether or not the processing is completed in step S48. If it is determined in step S48 that the process is not completed, the process returns to the spot setting determination process in step S41. If the process is completed, the present process is terminated.

  When the setting is made by inputting the telephone number (YES in step S42), the control means 10 adds the facility data in the map data stored in the map information storage means 12 and the facility data stored in the facility information storage means 13 to the facility data. It is determined whether or not the data of the corresponding telephone number is stored, and it is determined whether or not the position information corresponding to the telephone number can be specified (step S43). If the data corresponding to the input telephone number is not stored, or if there is data corresponding to the input telephone number but the position information cannot be specified (NO in step S43), the process proceeds to step S44.

  When the position information corresponding to the input telephone number can be specified (YES in step S43), the input destination point is specified using the position information, the destination is set, route search and route guidance are performed. (Step S46), the process proceeds to the end process of Step S48. In the end process, it is determined whether or not the route guidance process has ended. If the process has not ended, the process returns to the spot setting determination process in step S41, and if the process has ended, this procedure ends.

  In the process of step S44, the control means 10 determines whether or not there is a mobile terminal device T in the vicinity. This determination is performed by trying to establish communication with a nearby device by short-range wireless communication via the communication unit 16 and determining whether communication can be established. If there is a mobile terminal device T in the vicinity and communication is possible, the mobile terminal device T is accessed (communication is established) (step S45), the control means 10 transmits the telephone number input to the mobile terminal device T, and the location An information acquisition request is made, and the process proceeds to the flow chart of flow 2 (FIG. 5). On the other hand, when communication with the nearby mobile terminal device T is not possible (NO in step S44), a message that the input telephone number is not accumulated and the point cannot be set is notified (step S47).

  Referring to the flowchart shown in FIG. 5, the mobile terminal device T determines whether or not there is a request for acquiring position information from the navigation device N in the process of step S <b> 51. If there is a request (YES in step S51), the control means 20 searches the telephone book storage means 22 in step S52 and determines whether there is telephone book data corresponding to the telephone number received from the navigation device N (step S52). S53). If there is phone book data, it is determined whether or not there is location information in the data (step S54).

  If there is location information in the phone book data corresponding to the telephone number (YES in step S54), the mobile terminal device T sends (transfers) the location information to the navigation device N to reply, and if the answer is completed. The process ends.

  If the position information is not requested from the navigation device N (NO in step S51), the telephone book data corresponding to the requested telephone number is not stored in the telephone book storage means 22 (NO in step S53). If no location information is stored in the phone book data to be performed (NO in step S54), the portable terminal device T ends the process.

  Next, the operation procedure of the navigation device N after requesting the mobile terminal device T for location information corresponding to the telephone number will be described with reference to the flowchart of FIG. First, the navigation device N determines whether or not there has been a transfer (answer) of location information for the requested telephone number from the mobile terminal device T (step S61). When there is no transfer (response) of position information (or a response that there is no corresponding position information) (NO in step S61), the control means 10 sends an error message (point setting) via the output means 15. Display the message “impossible”) and finish the process.

  When there is data transfer (response) from the mobile terminal device T and position information can be acquired (YES in step S61), the control means 10 identifies the point input as the destination by the acquired position information, Setting is performed (step S62). When the destination is set, the control means 10 searches for a route based on the set destination and executes route guidance using the route information obtained as a result of the search (step S63). Proceed to processing. In the process of step S64, the end of the route guidance is determined, and when the route guidance ends, the process of the navigation device N ends.

  As described above, according to the navigation device N according to the present invention, when a location is set by inputting a telephone number, the navigation device N receives information corresponding to the telephone number, in particular, the telephone number. When there is no accumulation of the position information to be performed, it is possible to set the spot by acquiring the position information from the phone book data of the mobile terminal device T.

  That is, the phone book data accumulated in the phone book of the portable terminal device possessed by the user of the navigation device N is data collected by the user as needed, such as facility information accumulated in the navigation device N. In many cases, the data stored so as to be used for a large number of specific uses does not store data according to the personal taste, and there are cases where the point cannot be set. On the other hand, since the phone book data stored in the phone book of the portable terminal device T possessed by the user of the navigation device N is data collected by the user as needed, the location information is obtained from this phone book data. If acquired, it can be considered that there is a high probability that a point can be set by inputting a telephone number, which can contribute to setting a point by inputting a telephone number.
