Abstract

A method for location based access control in a wireless communication system is disclosed. The method comprises receiving, from an originating device, a request for access to a specific resource associated with location constraints, the location constraints being related to circular description or country description, checking whether location information of the originating device is present, acquiring the location information of the originating device according to type of the location constraints when the location information of the originating device is not present, and performing access control based on the acquired location information.

First claim

What is claimed is:

1 . A method for location based access control in a wireless communication system, comprising:
receiving, from an originating device, a request for access to a specific resource associated with location constraints, the location constraints being related to circular description or country description; checking whether location information of the originating device is present; acquiring the location information of the originating device according to type of the location constraints when the location information of the originating device is not present; and performing access control based on the acquired location information, wherein the acquiring of the location information of the originating device comprises: acquiring the location information of the originating device by subscribing to a location notification service toward a location server when the location constraints are related to the circular description; determining whether country in which the originating device is located is distinguished using an Internet protocol (IP) address of the originating device when the location constraints are related to the country description; and acquiring the location information of the originating device by requesting the location server to provide the location information of the originating device when the country is not distinguished using the IP address of the originating device.

2 . The method according to claim 1 , wherein the acquiring the location information of the originating device by subscribing to the location notification service toward the location server comprises:
setting a value corresponding to the circular description in a resource related to the location notification service; and receiving information on the location of the originating device according to the location notification service.

3 . The method according to claim 1 , wherein the acquiring the location information of the originating device by subscribing to the location notification service toward the location server comprises receiving a notification of location change of the originating device from the location server when the originating device enters or leaves a region corresponding to the circular description.

4 . The method according to claim 1 , wherein the performing access control based on the acquired location information comprises:
checking whether the acquired location information satisfies the location constraints; and transmitting a response to the request for access according to a result of the checking to the originating device.

5 . The method according to claim 1 , wherein the location constraints are included in a specific parameter in <accessControlPolicy> resource associated with the specific resource.

6 . An apparatus configured to perform location based access control in a wireless communication system, comprising:
a radio frequency (RF) unit; and a processor configured to control the RF unit, wherein the processor is configured: to receive, from an originating device, a request for access to a specific resource associated with location constraints, the location constraints being related to circular description or country description; to check whether location information of the originating device is present; to acquire the location information of the originating device according to type of the location constraints when the location information of the originating device is not present; and to perform access control based on the acquired location information, wherein the process is configured: to acquire the location information of the originating device by subscribing to a location notification service toward a location server when the location constraints are related to the circular description; to determine whether country in which the originating device is located is distinguished using an Internet protocol (IP) address of the originating device when the location constraints are related to the country description: and to acquire the location information of the originating device by requesting the location server to provide the location information of the originating device when the country is not distinguished using the IP address of the originating device.

7 . The apparatus according to claim 6 , wherein the processor is configured to set a value corresponding to the circular description in a resource related to the location notification service and to receive information on the location of the originating device according to the location notification service to acquire the location information of the originating device by subscribing to the location notification service toward the location server.

8 . The apparatus according to claim 6 , wherein the processor is configured to receive a notification of location change of the originating device from the location server when the originating device enters or leaves a region corresponding to the circular description to acquire the location information of the originating device by subscribing to the location notification service toward the location server.

9 . The apparatus according to claim 6 , wherein the processor is configured to check whether the acquired location information satisfies the location constraints and to transmit a response to the request for access according to a result of the checking to the originating device to perform access control based on the acquired location information.

10 . The apparatus according to claim 6 , wherein the location constraints are included in a specific parameter in <accessControlPolicy> resource associated with the specific resource.
