Transmits the charging information to the search server 914.

Here, in steps 924 and 938, it is assumed that 'https' is used for security and XML is used for structuring exchanged data.

Hereinafter, according to the fifth embodiment of the present invention, when the communication system has a separate location information server, the Internet service provider obtains the location information of the subscriber station through the location information server, and the paging of the subscriber station. Through the second method for obtaining the recently accessed cell ID as the location information is used. Here. As an example, a method of acquiring location information of a corresponding terminal using both of the above methods is described as an example. However, the second of the two methods may be used as an option.

Thereafter, the Internet provider selects more detailed and accurate values of the location information obtained through the two methods as location information of the terminal and provides a push service using the location information. If paging is selected, additionally, the advantage of reducing the delay time of the push service can be additionally obtained.

Specifically, the Internet service provider obtains the location information of the terminal from the location information server through the first scheme. At this time, the Internet service provider knows the acquired location information, but if the second option is selected as an option, the terminal requests paging to receive the cell ID when the terminal reconnects. Thereafter, the Internet service user compares the location information obtained from the location information server with the final cell ID through the paging, and selects the most recent location information or more detailed and accurate value as location information of the terminal. Accurate location information can be selected. Therefore, the delay time that occurs when the Internet service user provides the push type service to the terminal can be reduced. Here, an example of providing an advertisement with a push type service will be described.

10 is a flowchart of an advertisement service according to a fifth embodiment of the present invention.

Referring to FIG. 10, an advertisement server 1014 of an Internet provider providing a search service, a subscriber station 1000 subscribed to the search service, a base station RAS 1002 of a communication system (cell) in which the terminal is located, The ASN GW 1004 storing the last cell ID of the subscriber station 1000, the CSN 1006 responsible for connecting to the network, and the network information of the user are stored in the subscriber station 1000 and the Internet server. USI server 1008 in charge of the interface between the 1014, the billing server 1010 for charging the service used by the subscriber station 1000 and the location information server that stores the location information of the subscriber station 1000 1012.

Here, the Internet service provider uses both methods of paging the location information of the corresponding terminal and obtaining the location information through the location information server 1012 in order to reduce time delay in providing the advertisement service.

In step 1022, the advertisement server 1014 requests both the location information of the user terminal 1000 provided from the location information server and the final cell ID through paging to the USI server 1008.

In step 1028, the USI server 1008 requests the location information server 1012 for location information of the subscriber station 1000, and in step 1030, the location information server 1012 stores the subscriber station 1000. Location information is sent to the USI server 1008.

Since the method of receiving the location information of the subscriber station 1000 through paging is optionally requested in step 1022, the USI server 1008 communicates with the ASN GW 1004 in steps 1032 to 1036. The subscriber station 1000 requests the paging of the subscriber station 1000 through the RAS 1002. In step 1038 to 1042, the subscriber station 100 that receives the paging request performs the paging to determine the most recently accessed last cell ID. Transmitting to the USI server 1008 via the RAS 1002 and the ASN / GW 1004, if the method for obtaining location information through the paging is not selected, steps 1032 to 1042 are omitted. .

In step 1048, the USI server 1008 delivers the location information of the subscriber station 1000 to the advertisement server 1014. In step 1050, the advertisement server 1014 receiving the location information transmits an advertisement utilizing the location information of the subscriber station 1000 to the subscriber station 1000.

As shown in FIG. 7, the location information of the subscriber station 1000 is the USI server 1008, that is, the network provider is a service provided to the Internet provider. After the operation, it notifies the internet service provider of the result. In step 1052, the advertisement server 1014 requests the USI server 1008 to update the charging information, and the USI server 1008 indicates that the location information of the user terminal 1000 has been provided. In operation 1010, the corresponding billing information is transmitted to the advertisement server 1014 in step 1054.

11 is a flowchart of providing a location-based internet service performed by an internet server according to a sixth embodiment of the present invention.

Referring to FIG. 11, in step 1100, the Internet server receives a request for providing a web portal page from a subscriber station and proceeds to step 1200.

In step 1200, the Internet server interoperates with the AN DB to determine whether the network to which the subscriber terminal accesses supports the USI. As a result of the determination, if the network to which the subscriber terminal is able to support the USI, the process proceeds to step 1300, and if the USI support is not possible, proceeds to step 1400.

In step 1300, the Internet server provides a web portal page including an option box capable of location-based search service to the subscriber terminal. In step 1400, the Internet server provides the subscriber terminal with a web portal page that does not include or disables an option box that enables location-based search service.
