As shown in FIG. 3, when the mobile communication terminal 320 moves from the mobile internet service area 330 to the area outside the mobile internet service area 340, the mobile internet module can no longer be provided with the mobile internet service. Through 110, the location of the mobile communication terminal 320 cannot be inquired. Therefore, in this case, continuously inquiring the position of the mobile communication terminal 320 through the portable Internet module 110 is to bring unnecessary consumption of power.

Accordingly, the mobile communication terminal 320 according to the present invention moves from the mobile internet service area 330 to the outside of the mobile internet service area 340 in order to determine whether to supply power to the mobile internet module 110. Sends a location query service request 201. Since the mobile communication terminal 320 is located at the boundary of the portable Internet service area, the location inquiry module 120 is used for accurate location inquiry.

As an example, the mobile communication terminal 320 may be out of the portable Internet service area when the strength of the wireless signal received from the portable Internet base station 310 through the portable internet module 110 is less than or equal to a threshold, or may be out of the portable Internet service area. It is determined that the likelihood is high, and the location inquiry service request 201 is transmitted to confirm the location of the mobile internet service area. The mobile communication terminal 320 may refer to strength information expressed as a Received Signal Strength Indication (RSSI) or a Carrier to Interference and Noise Ratio (CINR) value to determine whether to transmit the location inquiry service request 201. .

As another example, the mobile communication terminal 320 may refer to the moving direction of the terminal 320 to determine whether to transmit the location inquiry service request 201. That is, when the mobile communication terminal 320 is moving in a direction away from the portable Internet service area, the location inquiry service request 201 may be transmitted near the boundary. The mobile communication terminal 320 may calculate a moving direction based on the accumulated and stored location information 202. In addition, the current location information 202 or the above-mentioned strength information of the wireless signal may be referred to together with the moving direction of the terminal 320.

Meanwhile, according to another embodiment of the present invention, the mobile communication terminal 100 receives the location information transmitted in response to the location registration request transmitted to the location inquiry database through the location inquiry module 120 of the mobile communication terminal. Location information can be inquired.

According to the present embodiment, when the mobile communication terminal 100 requests a location registration to a location inquiry database under a specific condition, the mobile communication terminal 100 uses location information received by the mobile communication terminal as a response to the location registration request. The location of the mobile communication terminal can be inquired.

When the mobile communication terminal transmits a location registration request, a change in a zone or a user zone when the mobile communication terminal has a location area in the location lookup network, for example, the location lookup network is a CDMA communication network. There may be this. That is, when the mobile communication terminal enters or exits a location area such as a zone or a user zone, the location inquiry module 120 transmits a location registration request to a location inquiry database associated with the location inquiry network.

Alternatively, the location inquiry module 120 may transmit a location registration request when the power supply state of the mobile communication terminal 100 is changed, that is, when the mobile communication terminal 100 is turned on or off. In case of location registration request through CDMA communication network, in addition to the above-mentioned change of location area or change of power supply status, periodic registration based on timer, and when base station commands direct registration to terminal, There are various types of location registration methods, such as registration that occurs during the origination and paging response process, and the location registration request according to the present embodiment is performed through a location inquiry network such as a CDMA communication network.
