  Further, the serial number of the searchable mobile terminal device 5 (1) having the purchase history of the telephone number does not match the serial number managed by the management unit 33, and the serial number of the searchable mobile terminal device 5 (1). If there is a registered telephone number with a SIM (if the SIM is replaced), there is no purchase history of the telephone number (purchasing history omission), and registration with the manufacturing number of the searched mobile terminal device 5 (1) When there is a completed telephone number (when the SIM is replaced), the scale of the map on which the position information sent from the reverse mobile terminal device 5 (2) is superimposed is reduced and transmitted to the PC1.

Next, a mobile terminal search method according to an embodiment of the present invention will be described.
FIG. 4 is a flowchart for explaining the portable terminal search method according to the embodiment of the present invention. In the figure, first, the user of PC1 who is a searcher performs an operation of searching for the position of his / her portable terminal device 5 using PC1. In this case, the user inputs the telephone number of his / her mobile terminal device 5. Thereby, a position search request is transmitted from the PC 1 to the mobile communication center 3 (step ST11). When receiving the position search request transmitted from the PC 1, the mobile communication center 3 searches for the position of the searched mobile terminal device 5 (1). FIG. 5 is a display example on the PC 1 during the search for the mobile terminal device 5 (1) to be searched. In this example, a message “Searching now. Search may take time depending on the radio wave condition of the mobile phone you want to search for” is displayed. When the position of the searchable mobile terminal device 5 (1) is found, the searchable mobile terminal device 5 (1) is requested for a production number and position information (step ST12).

  When a mobile phone center 3 receives a manufacturing number and position information request from the mobile communication center 3, the searched mobile terminal device 5 (1) transmits the manufacturing number and position information to the mobile communication center 3 in response to the request (step ST13). ). When the mobile communication center 3 receives the manufacturing number and the position information from the searched mobile terminal device 5 (1), the mobile communication center 3 obtains them and communicates with the searched mobile terminal device 5 (1). Is acquired (step ST14).

  Next, the presence / absence of the purchase history of the telephone number input by the user is determined. If there is a purchase history, based on the manufacturing number of the searched mobile terminal device 5 (1) and the correspondence information managed by the management unit 33. Then, it is determined whether or not the serial number of the user's portable terminal device 5 matches (step ST16). In this determination, if both the production numbers match, as a normal search, the scale of the map on which the position information sent from the searched mobile terminal device 5 (1) is superimposed is enlarged, and the map is displayed as PC1. (Step ST17). In this case, the SIM card is not replaced, and the telephone number and manufacturing number of the searched mobile terminal device 5 (1) match the telephone number and manufacturing number managed by the management unit 33.

  For example, when searching for a portable terminal device “090-1234-XXX” on the PC 1, the mobile communication center 3 searches for a portable terminal device “090-1234-XXX” and is found at this time. Assuming that the mobile terminal device to be searched is the mobile terminal device 5 (1) to be searched, the mobile terminal device 5 (1) to be searched is requested for the serial number and the position information. Then, when the serial number of “123456789” is sent from the searched mobile terminal device 5 (1), the serial number “123456789” and the telephone number “090-1234-XXX” that is paired with the serial number are entered. Since it exists in the management part 33, the to-be-searched portable terminal device 5 (1) is the portable terminal device itself of search object. Therefore, a map with a scale that clearly shows the location of the searched mobile terminal device 5 (1) is transmitted to the PC 1.

  FIG. 6 is an example of a highly accurate map with an enlarged scale. In this figure, the star indicates the position of the searched mobile terminal device 5 (1).

  Returning to the flowchart of FIG. 4, in the determination of step ST <b> 16, when the serial number of the searched mobile terminal device 5 (1) does not match the serial number of the user's mobile terminal device 5 managed by the management unit 33. Then, it is determined whether or not the telephone number having the manufacturing number of the searched portable terminal device 5 (1) exists in the management unit 33 (step ST18). The scale of the map on which the position information sent from the terminal device 5 (1) is superimposed is enlarged and transmitted to the PC 1 (step ST19). That is, also in this case, a map of a reduced scale that clearly shows the location of the searched mobile terminal device 5 (1) is transmitted to the PC 1. Until the model change is performed and the new model serial number and the telephone number used so far are associated with each other and registered in the management unit 33, step ST16 (No) → step ST18 (No) → step ST19 It becomes processing. After that, when the manufacturing number of the new model and the telephone number used so far are registered in the management unit 33, the regular search is performed, and the process of step ST16 (Yes) → step ST17 is performed.

  When the serial number of the mobile terminal device 5 (1) to be searched does not match the serial number of the mobile terminal device 5 of the user managed by the management unit 33, the serial number of the mobile terminal device 5 (1) to be searched is If the telephone number is in the management unit 33, it is assumed that the SIM has been replaced, and the management number is sent from the information managed by the management unit 33 using the manufacturing number sent from the searched mobile terminal device 5 (1). Get a phone number. Then, a base station (not shown) that can communicate with the mobile terminal device 5 (that is, the reverse mobile terminal device 5 (2)) having the telephone number (that is, the reverse phone number) acquired from the management unit 33 is searched. When a corresponding base station is found, a serial number and position information are requested from the reverse lookup portable terminal device 5 (2) via the base station (step ST20).

  Here, in the case where the serial number of the mobile terminal device 5 (1) to be searched does not match the serial number of the mobile terminal device 5 of the user managed by the management unit 33, the mobile terminal device 5 (1) to be searched The case where the telephone number having the production number is in the management unit 33 is, for example, that the telephone number input by the user from the PC 1 is “090-1234-XXX” in FIG. When the device is the searched portable terminal device 5 (1) with the production number “223456789”, and the telephone number “090-2234-XXX” is in the management unit 33 for the production number “223456789” It is. Since the manufacturing number paired with the telephone number “090-1234-XX” entered by the user is “123456789”, it does not match the manufacturing number “223456789”. The telephone number “090-2234-XXX” paired with the manufacturing number “223456789”. Incidentally, it is a telephone number obtained by reversely subtracting the telephone number “090-2234-xxx” from the production number “223456789”. The mobile terminal device with the reverse phone number is the reverse mobile terminal device.

  When the manufacturing number and the position information request are sent from the mobile communication center 3, the reverse lookup mobile terminal device 5 (2) transmits the manufacturing number and the position information to the mobile communication center 3 in response to the request (step ST21). ). When the mobile communication center 3 receives the manufacturing number and the position information from the reverse lookup mobile terminal device 5 (2), the mobile communication center 3 acquires these and communicates with the reverse lookup mobile terminal device 5 (2). Get location information. Then, the location information of the base station communicating with the reverse lookup mobile terminal device 5 (2) is transmitted to the PC 1 (step ST22). At this time, the reverse lookup telephone number may be transmitted to the PC 1 together, or the location information of the base station communicating with the mobile terminal device 5 (2) is superimposed on the map, and the scale is reduced to the PC 1. You may make it transmit. FIG. 7 is an example of a low-accuracy map with a reduced scale.

  On the other hand, if it is determined in step ST15 that there is no purchase history of the telephone number input by the user, it is determined whether or not the management unit 33 has a telephone number having the manufacturing number of the searchable mobile terminal device 5 (1) (step ST15). ST23) If there is a SIM replacement in some cases, the process proceeds to step ST20 and the same processing as described above is performed. On the other hand, if the management unit 33 does not have a telephone number having the manufacturing number of the searched mobile terminal device 5 (1), it is sent from the searched mobile terminal device 5 (1) as a forgotten purchase registration of the telephone number. The scale of the map on which the position information is superimposed is enlarged and transmitted to the PC 1 (step ST24).

  As described above, in the mobile terminal search system according to the present embodiment, the management unit 33 of the mobile communication center 3 manages the telephone number, manufacturing number, and purchase history information of the mobile terminal device 5, and the searched mobile terminal device. If there is a purchase history of the telephone number of 5 (1), the production number of the portable terminal device 5 (1) to be searched is compared with the production number managed, and if both production numbers match, a regular search is performed. The position information of the searchable mobile terminal device 5 (1) is transmitted to the searcher by superimposing it on the map, and even if the serial numbers do not match, it is paired with the serial number of the searchable mobile terminal device 5 (1). If the phone number is not registered in the management unit 33, the position information of the searchable portable terminal device 5 (1) is superimposed on the map and transmitted to the searcher as a search after changing the model, and the serial numbers of both are identical. I did not, and searched mobile terminal device 5 (1) If the telephone number paired with the serial number is registered in the management unit 33, the telephone number managed using the serial number of the searched mobile terminal device 5 (1) is reversed, and the reverse telephone number The position information of the reverse mobile terminal device 5 (2) is acquired, and the acquired position information is superimposed on the map and transmitted to the searcher. Therefore, even if the pair of the mobile terminal device 5 and the SIM card (not shown) is not the original one, the searchable mobile terminal device 5 (1) can be searched by reversely retrieving the telephone number from the manufacturing number. .

  In the present embodiment, the map including the position information is transmitted to the PC 1 via the gateway 2, but may be transmitted using a network such as the Internet. Further, when using a network, the position search may be performed not by the mobile communication center 3 but by a dedicated server group (Web server, positioning server, etc.).

  Moreover, although the said embodiment demonstrated the aspect which inquires a manufacturing number to a to-be-searched portable terminal device for every search, this invention is not limited to this, The position of a portable terminal device is mobile communication center 3 When registering to the mobile communication center 3, the manufacturing number may be acquired from the pairing information of the telephone number and the manufacturing number managed by the management unit 33 of the mobile communication center 3. Thereby, acquisition of a manufacturing number can be performed easily.

  The present invention is not limited to the above-described embodiment, and can be implemented with various modifications. For example, the processing unit and the processing procedure can be changed as appropriate without departing from the scope of the present invention. Other modifications can be made without departing from the scope of the present invention.

  The present invention is applicable to a system that searches for a mobile terminal device that has been misplaced or lost.
