Abstract

A location information tagging method and system for location-based services in a wireless communication system are provided. In the method, if it is determined that a service request message received from a device is being sent to an application server for providing a service based on a location of the device, location information about a base station is tagged to the service request message. The service request message with the tagged location information is transmitted to the application server. Therefore, the application server can obtain location information about the device by merely depending on the message received from the device without referring to a conventional location service server. This reduces a service response time and also rapidly offers a location-based service.

Claims

1. A location information tagging method for a location-based service in a wireless communication system, the method comprising:

determining whether a service request message received from a device is being sent to an application server for providing a service based on a location of the device;

if it is determined that the service request message is being sent to the application server, tagging location information about a base station to the service request message; and

transmitting the service request message with the tagged location information to the application server.

2. The method of claim 1, wherein the tagging of the location information includes tagging a location resolution of the location information to the service request message.

3. The method of claim 1, wherein the transmitting of the service request message includes reproducing the service request message by considering the tagged location information.

4. The method of claim 1, wherein the determining whether the service request message is being sent to the application server includes comparing information contained in the service request message with information about the application server.

5. The method of claim 4, wherein the information about the application server comprises at least one of a destination Internet Protocol (IP) address, a protocol Identifier (ID), a port number, and a message type.

6. A location information tagging method for a location-based service in a wireless communication system, the method comprising:

determining whether a service request message is going to be sent from a device to an application server for providing a service based on a location of the device;

if it is determined that the service request message is going to be sent to the application server, tagging location information about the device to the service request message; and

transmitting the service request message with the tagged location information to the application server.

7. A location information tagging apparatus for a location-based service in a wireless communication system, the apparatus comprising:

an application server table storage unit for storing information about an application server for providing a service based on a location of a device;

a packet examination unit for determining whether a service request message received from the device is being sent to the application server; and

a tagging execution unit for tagging location information about a base station to the service request message if it is determined that the service request message is being sent to the application server.

8. The apparatus of claim 7, further comprising:

a tag information storage unit for storing at least one of the location information about the base station, a location resolution of the location information, and a bandwidth of a wireless environment between the device and the base station.

9. The apparatus of claim 7, wherein the packet examination unit detects the application server by comparing the information stored in the application server table storage unit with information contained in the service request message.

10. The apparatus of claim 8, wherein the tagging execution unit tags the location resolution of the location information to the service request message.

11. The apparatus of claim 7, wherein the tagging execution unit reproduces the service request message by considering the tagged location information.

12. A location information tagging apparatus for a location-based service in a wireless communication system, the apparatus comprising:

an application server table storage unit for storing information about an application server for providing a service based on a location of a device;

a packet examination unit for determining whether a service request message is going to be sent to the application server; and

a tagging execution unit for tagging location information about the device to the service request message if it is determined that the service request message is going to be sent to the application server.
