Abstract

An apparatus and method for transferring content rights by a multimedia message in a mobile communication system are provided, in which a DRM server transmits a right object associated with contents to an MS, upon request of the MS, a transmitting MS generates, upon generation of an event triggering a right object transfer, the right object with content rights to be transferred and a storage right object with remaining content rights, stores the storage right object, and transmits a message including the right object to a receiving MS, and the receiving MS receives the right object by the message from the transmitting MS and stores the right object.

Claims

1. A mobile communication system for transferring content rights, the system comprising:

a digital rights management (DRM) server for transmitting a right object (RO) associated with contents to a receiving mobile station (MS), upon a request of the receiving mobile station;

a transmitting mobile station for, upon generation of an event triggering an right object transfer, generating the right object for outgoing content rights to be transferred and a storage right object for remaining content rights, storing the storage right object, and transmitting a message including the right object to the receiving mobile station; and

the receiving mobile station for receiving the right object by the message from the transmitting mobile station and storing the right object.

2. The mobile communication system of claim 1, wherein the DRM server includes fingerprint information specific to the right object in the right object.

3. The mobile communication system of claim 2, wherein if the DRM server receives the fingerprint information from the transmitting mobile station and the receiving mobile station during the right object transfer, the DRM server stores the fingerprint information along with information about the transmitting mobile station and the receiving mobile station.

4. The mobile communication system of claim 1, wherein upon successful completion of the message transmission, the transmitting mobile station stores only the storage right object.

5. The mobile communication system of claim 1, wherein the transmitting mobile station transmits the message including the right object to the receiving mobile station by a multimedia message system (MMS).

6. The mobile communication system of claim 2, wherein the transmitting mobile station transmits the fingerprint information included in the right object to the DRM server, after the message transmission.

7. The mobile communication system of claim 6, wherein the transmitting mobile station transmits the fingerprint information to the DRM server by one of a wireless application protocol and a short message service.

8. The mobile communication system of claim 1, wherein upon receipt of the message including the right object, the receiving mobile station stores the-received right object without redundancy.

9. The mobile communication system of claim 2, wherein the receiving mobile station transmits the fingerprint information included in the right object to the DRM server, after the message reception.

10. The mobile communication system of claim 9, wherein the receiving mobile station transmits the fingerprint information to the DRM server by one of a wireless application protocol and a short message service.

11. A mobile station (MS) for transferring content rights, the mobile station comprising:

a memory for storing Right Objects (ROs);

a transmitter and receiver for transmitting and receiving a message including a right object;

a right object manager for, upon generation of an event triggering a right object transfer, generating the right object for outgoing content rights to be transferred and a storage right object for remaining content rights, and controlling updating the right object with the storage right object in the memory; and

a message processor for generating a message including the right object and controlling the message to be transmitted.

12. The mobile station of claim 11, wherein the right object manager stores only the storage right object, when the message including the right object is transmitted.

13. The mobile station of claim 11, wherein the right object includes fingerprint information specific to the right object.

14. The mobile station of claim 11, wherein upon receipt of the message including the right object, the right object manager stores the received right object without redundancy.

15. The mobile station of claim 11, wherein when the right object is wholly transferred, the right object manager controls the transferred right object to be deleted from the memory, without generating the storage right object.

16. The mobile station of claim 11, wherein the transmitter and the receiver transmit the message by a multimedia messaging system.

17. The mobile station of claim 13, further comprising a fingerprint information processor for, when the right object is transferred or received, transmitting fingerprint information included in the right object to a digital rights management (DRM) server.

18. The mobile station of claim 17, wherein the fingerprint information is transmitted to the DRM server by one of a wireless application protocol and a short message service.

19. A method for transferring content rights in mobile station (MS), the method comprising:

receiving content rights to be transferred and checking a count of the content rights, upon generation of an event triggering a right object (RO) transfer;

generating a right object for outgoing content rights to be transferred;

generating a storage right object for remaining content rights and storing the storage right object to update the right object;

generating a message including the right object; and

transmitting the message.

20. The method of claim 19, further comprising making sure that only the storage right object is stored, after the message transmission.

21. The method of claim 19, wherein the right object includes fingerprint information specific to the right object.

22. The method of claim 19, wherein the storage right object generation and storing comprises deleting the right object after it is transferred without generating the storage right object.

23. The method of claim 19, wherein the message transmission comprises transmitting the message by a multimedia messaging system.

24. The method of claim 21, further comprising transmitting the fingerprint information included in the right object to a digital rights management (DRM) server, after the message transmission.

25. The method of claim 24, wherein the fingerprint information transmission comprises transmitting the fingerprint information to the DRM server by one of a wireless application protocol and a short message service.

26. The method of claim 21, further comprising transmitting the fingerprint information included in the right object to the DRM server by a mobile station that receives the message.

27. A Computer-readable recording medium having recorded thereon a program for transferring content rights in mobile station (MS), comprising;

a first code segment for receiving content rights to be transferred and checking a count of the content rights, upon generation of an event triggering a right object (RO) transfer;

a second code segment for generating a right object for outgoing content rights to be transferred;

a third code segment for generating a storage right object for remaining content rights and storing the storage right object to update the right object;

a fourth code segment for generating a message including the right object; and

a fifth code segment for transmitting the message.
