The prefix table stores HLR 400 information per prefix of the MS 100 whose location is to be tracked.

In addition, the PDE 500 acquires location information of the MS 100 to be tracked through a paging response message provided from the MSC 300, generates an SMS message including the obtained location information, and requests location service. To be provided to the MS 100.

Next, the location service providing method of the location service providing system having the above configuration will be described in detail.

3 is a signal flow diagram illustrating a location service providing method according to an embodiment of the present invention.

As shown in FIG. 3, the first MS 100a may receive a location information request of the second MS 100b from the subscriber (S101).

When the first MS 100a receives the location information request message of the second MS 100b from the user, the first MS 100a receives the location service request message including its MDN (Mobile Directory Number) and the MDN of the second MS 100b. In S102, the first MSC 300a is transmitted (S103), and the first MSC 300a transmits the received location service request message to the PDE 500 again (S104).

When the PDE 500 receives the location service request message, the PDE 500 stores a subscriber database table that stores whether the first MS 100a serving as the location service requesting party and the second MS 100b serving as the tracking party is the registered subscriber of the location service. Determine through (S105).

That is, the PDE 500 allows the first MS 100a subscriber to register with the location service and request the location service, and allows the second MS 100b subscriber to provide his location to the first MS 100a subscriber. By identifying whether the registration is to be performed, service authentication of the first MS 100a and the second MS 100b is performed.

If the first MS 100a and the second MS 100b are determined to be subscribers of location services, the PDE 500 transmits an authentication success message to the first MSC 300a (S106), and receives the first MSC 300a. ) Provides the location service guide message to the first MS 100a through the first BSC 200a (S107).

For example, the first MSC 300a provides a location service guide message “I will send a text message about the location of the second MS 100b” to the first MS 100a so that the first MS 100a receives voice or voice messages. Output to the subscriber via the image information.

After the first MSC 300a provides the location service guide message to the first MS 100a, the first MSC 300a terminates the connection with the first MS 100a.

Meanwhile, when the PDE 500 transmits an authentication success message to the first MSC 300a, the PDE 500 determines which HLR 400 the prefix included in the MDN of the subscriber of the second MS 100b belongs to via the prefix table.

The PDE 500 includes the MDN of the second MS 100b in order to identify the MSC 300 that is being serviced by the subscriber of the second MS 100b, that is, the MSC 300 where the second MS 100b is located. The determined location request message is transmitted to the identified HLR 400 (S110).

When the HLR 400 receives the location request message from the PDE 500, the HLR 400 grasps the MIN corresponding to the MDN of the second MS 100b and the MSC 300 where the second MS 100b is located. The included location response message is transmitted to the PDE 500 (S111). In FIG. 3, the MSC 300 in which the second MS 100b is located is referred to as a second MSC 300b.

When the PDE 500 receives the information from the MSC 300 where the MIN of the second MS 100b and the second MS 100b are located, that is, the information of the second MSC 300b through the location request message from the HLR 400, the PDE 500 receives the information. A paging request message is transmitted to the second MSC 300b to acquire location information of the 2MS 100b (S112).

When the paging request message is provided, the second MSC 300b transmits the provided paging request message to the second BSC 200b (S113), and the second BSC 200b according to the provided paging request message is presently present in the second MS 100b. Paging for positioning is performed (S114).

The second BSC 200b acquires the location information of the second MS 100b in sector units through paging, and includes the obtained location information of the second MS 100b and the address information of the second BSC 200b. The response message is transmitted to the second MSC 300b (S115).

When the paging response message is provided from the second BSC 200b, the second MSC 300b includes its address information in the provided paging response message and transmits it to the PDE 500 (S116).

If the PDE 500 is provided with a paging response message from the second MSC 300b, the PDE 500 includes address information of the second MSC 300b included in the provided paging response message, address information of the second BSC 200b, and the second MS 100b. Generates an SMS message including the location information of the second MS (100b) corresponding to the location service request message provided from the first MS (100a) via the location information, and transmits the generated SMS message to the first MSC (300a) ( S117).

When an SMS message including location information is provided from the PDE 500, the first MSC 300a transmits the provided SMS message to the first MS 100a through the first BSC 200a (S118).

When the SMS message is provided from the first BSC 200a, the first MS 100a outputs the provided SMS message to the user as voice or image information.

Accordingly, the subscriber of the first MS 100a may receive the requested location information of the second MS 100b by SMS.

As such, the location service providing system may provide the location service to the MS 100 using only a voice network including the PDE 500 for obtaining location information.

For example, for each service method, if any MS 100 subscriber wants to be provided with location service, the subscriber can register with the location service by inputting "* 71" using the keypad of the MS 100. Can be.

That is, when the MS 100 receives "* 71" from the subscriber, the MS 100 determines this as a location service registration request input, and sends a location service registration request message to the PDE 500 through the BSC 200 and the MSC 300. Will be sent.

Therefore, when the location service registration request message is provided, the PDE 500 stores the location service registration of the corresponding MS 100 subscriber in the stored subscriber database table.

As such, the MS 100 registered in the location service enters "73+ tracking subscriber (that is, the number of the MS 100 that wants to provide location service)" through the keypad, thereby providing the location information of the corresponding tracking subscriber. 500 may be provided.

On the other hand, the tracking subscriber can enter the "* 75" through the keypad of the MS 100, it is possible to provide its location information to the location request side.

In addition, the tracking subscriber does not want to provide his location information by inputting "* 76 + requesting subscriber (ie, the number of the MS 100 requesting his location information)" through the keypad of the MS 100. The subscriber may not be provided with his location information.

On the other hand, the specific code shown in Figure 4 is used as an example in the present invention, by using a combination of other numbers of numbers or special characters, it is possible to pre-set the service method according to each combination.
