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 by an apparatus in a communication system, the method comprising:

detecting data transmitted between a device, to which a new temporary identifier is assigned, and a first server;

transmitting, to a second server, a first message for requesting information for a previous temporary identifier of the device;

in response to transmitting the first message, receiving, from the second server, a second message;

if the previous temporary identifier of the device is not included in the second message, managing a user context of the device based on the new temporary identifier of the device; and

if the previous temporary identifier of the device is included in the second message, managing the user context of the device by mapping the previous temporary identifier of the device and the new temporary identifier of the device.

2. The method of claim 1, wherein the previous temporary identifier information comprises information for a previous IP address or a previous alias used by the device before a new IP address or a new alias is assigned.

3. The method of claim 2, wherein the managing of the user context of the device by mapping the previous temporary identifier of the device and the new temporary identifier of the device comprises updating the previous IP address or the previous alias of the device to the new IP address or the new alias assigned currently for the device.

4. The method of claim 1, wherein the user context includes at least one of user activity information or user service usage information those comprise at least one of purchase history, user location, preference, click history, or social network server (SNS) information.

5. The method of claim 1, wherein the user context of the device is managed without a user identification of the device.

6. An apparatus in a communication system, the apparatus comprising:

a transceiver;

a storage unit for storing a user context; and

at least one processor configured to;

detect, via the transceiver, data transmitted between a device, to which a new temporary identifier is assigned, and a first server;

transmit, to a second server, a first message for requesting information for a previous temporary identifier of the device;

in response to transmitting the first message, receive, via the transceiver, from the second server, a second message;

if the previous temporary identifier of the device is not included in the second message, manage a user context of the device based on the new temporary identifier of the device; and

if the previous temporary identifier of the device is included in the second message, manage the user context of the device by mapping the previous temporary identifier of the device and the new temporary identifier of the device.

7. The apparatus of claim 6, wherein the previous temporary identifier information comprises information for a previous IP address or a previous alias used by the device before a new IP address or a new alias is assigned.

8. The apparatus of claim 7, wherein the at least one processor is further configured to update the previous IP address or the previous alias of the device to the new IP address or the new alias assigned currently for the device.

9. The apparatus of claim 6, wherein the user context includes at least one of user activity information or user service usage information those comprise at least one of purchase history, user location, preference, click history, or social network server (SNS) information.

10. The apparatus of claim 6, wherein the at least one processor is configured to manage the user context of the device without a user identification of the device.

11. A method by an apparatus in a communication system, the method comprising:

receiving, from a first server, a first message for requesting a previous temporary identifier of a device, the device to which a new temporary identifier is assigned; and

in response to receiving the first message, transmitting, to the first server, a second message,

wherein a user context of the device is managed based on the new temporary identifier of the device if the previous temporary identifier of the device is not included in the second message, and

the user context of the device is managed by mapping the previous temporary identifier of the device and the new temporary identifier of the device if the previous temporary identifier of the device is included in the second message.

12. The method of claim 11, wherein the previous temporary identifier information comprises information for a previous IP address or a previous alias used by the device before a new IP address or a new alias is assigned.

13. The method of claim 12, wherein the previous IP address or the previous alias of the device is updated to the new IP address or the new alias assigned currently for the device if the previous temporary identifier of the device is included in the second message.

14. The method of claim 11, wherein the user context includes at least one of user activity information or user service usage information those comprise at least one of purchase history, user location, preference, click history, or social network server (SNS) information.

15. The method of claim 11, wherein the user context of the device is managed without a user identification of the device.

16. An apparatus in a communication system, the apparatus comprising:

a transceiver;

a storage unit for storing a previous temporary identifier and a new temporary identifier of a device; and

at least one processor configured to;

receive, via the transceiver, from a first server, a first message for requesting the previous temporary identifier of the device, the device to which the new temporary identifier is assigned; and

in response to receiving the first message, transmit, via the transceiver, to the first server, a second message,

wherein a user context of the device is managed based on the new temporary identifier of the device if the previous temporary identifier of the device is not included in the second message, and

wherein the user context of the device is managed by mapping the previous temporary identifier of the device and the new temporary identifier of the device if the previous temporary identifier of the device is included in the second message.

17. The apparatus of claim 16, wherein the previous temporary identifier information comprises information for a previous IP address or a previous alias used by the device before a new IP address or a new alias is assigned.

18. The apparatus of claim 17, wherein the at least one processor is further configured to update the previous IP address or the previous alias of the device to the new IP address or the new alias assigned currently for the device if the previous temporary identifier of the device is included in the second message.

19. The apparatus of claim 16, wherein the user context includes at least one of user activity information or user service usage information those comprise at least one of purchase history, user location, preference, click history, or social network server (SNS) information.

20. The apparatus of claim 16, wherein the user context of the device is managed without a user identification of the device.
