Abstract

The present invention relates to a system configuration and an apparatus for preventing the infringement of user privacy, and for collecting and analyzing information regardless of the service feature and type, while a system providing a context aware service collects and analyzes user information. The present invention discloses a method of configuring and using a context analyzer and a device profile database in order for the system providing the context aware service to collect and analyze information regardless of the service feature and type.

Claims

1. A method for managing context in a communication system, the method comprising:

detecting a packet transmitted between a device and a server;

requesting a device profile database for information on an IP address of the device by sending an IP request message;

receiving an IP response message from the device profile database; and

updating the context according to the IP address information in the IP response message.

2. The method of claim 1, wherein the IP address information comprises an old IP address used by the device before current IP address is assigned.

3. The method of claim 2, wherein the IP response message excludes, when the device connects to the system initially, the information on an IP address used by the device.

4. The method of claim 2, wherein the IP response message comprises, when the device has connected to the system previously, the information on the IP address used by the device.

5. The method of claim 4, wherein the updating of the context comprises updating the previously used IP address included in the context to the IP address assigned currently.

6. The method of claim 1, wherein the information on the IP address comprises an alias of the device using the IP address assigned currently.

7. The method of claim 1, wherein the context is user information comprising at least one of purchase history, user location, preference, click history, and Social Network Server (SNS) information.

8. An apparatus for managing context in a communication system, the apparatus comprising:

an interface which is responsible for wired or wireless communication with at least one node;

a storage unit which stores context information associated with an IP address; and

a control unit which detects a packet transmitted between a device and a server, requests a device profile database for information on an IP address of the device by sending an IP request message, and receives an IP response message from the device profile database, and updates the context according to the IP address information in the IP response message.

9. The apparatus of claim 8, wherein the IP address information comprises an old IP address used by the device before current IP address is assigned.

10. The apparatus of claim 9, wherein the IP response message excludes, when the device connects to the system initially, the information on an IP address used by the device.

11. The apparatus of claim 9, wherein the IP response message comprises, when the device has connected to the system previously, the information on the IP address used by the device.

12. The apparatus of claim 11, wherein the control unit updates the previously used IP address included in the context to the IP address assigned currently.

13. The apparatus of claim 8, wherein the information on the IP address comprises an alias of the device using the IP address assigned currently.

14. The apparatus of claim 8, wherein the context is user information comprising at least one of purchase history, user location, preference, click history, and Social Network Server (SNS) information.
