Abstract

A method provides control of access to shared content in a communication system. The method comprises obtaining presence information with at least one access criterion associated with an access to shared content. The method further comprises receiving an access request requesting an access to at least one part of the shared content. The method further comprises verifying the access request against the at least one access criterion. The method further comprises processing the access request based on a result of the step of verifying. Furthermore, a controlling entity is configured to execute the method.

Claims

1. A method for controlling access to shared content in a communication system, the method comprising:

obtaining presence information with at least one access criterion associated with an access to shared content;

receiving an access request requesting an access to at least one part of the shared content;

verifying the access request against the at least one access criterion; and

processing the access request based on a result of the step of verifying.

2. The method according to claim 1, wherein the step of obtaining comprises allowing a user sharing the shared content to set the at least one access criterion for the at least one part of the shared content.

3. The method according to claim 1, wherein the step of receiving comprises receiving a session initiation protocol message identifying the at least one part of the shared content and a requesting party.

4. The method according to claim 3, wherein the step of verifying comprises verifying whether the at least one access criterion allows the requesting party to access the at least one part of the shared content.

5. The method according to claim 4, wherein the step of verifying comprises mapping the at least one part of the shared content with an address of an entity storing the presence information for the at least one part of the shared content.

6. The method according to claim 5, wherein the step of verifying further comprises enquiring the presence information from said entity.

7. The method according to claim 4, wherein the step of verifying comprises mapping the at least one part of the shared content with the presence information stored together with the at least one part of the shared content.

8. The method according to any of claims 3, wherein the step of processing comprises allowing the access to the at least one part of the shared content when the step of verifying shows that the at least one access criterion allows the requesting party to access the at least one part of the shared content.

9. The method according to any of claims 3, wherein the step of processing comprises denying the access to the at least one part of the shared content when the step of verifying shows that the at least one access criterion does not allow the requesting party to access the at least one part of the shared content.

10. A computer program embodied on a computer readable medium, said computer program controlling a computing system to perform the steps of:

obtaining presence information with at least one access criterion associated with an access to shared content;

receiving an access request requesting an access to at least one part of the shared content;

verifying the access request against the at least one access criterion; and

processing the access request based on a result of the step of verifying.

11. A controlling entity for controlling access to shared content in a communication system, the controlling entity configured to:

obtain presence information with at least one access criterion associated with an access to shared content;

receive an access request requesting an access to at least one part of the shared content;

verify the access request against the at least one access criterion; and

process the access request based on a result of the verification.

13. The controlling entity according to claim 11, comprising an application server implemented in a communication device.

14. The controlling entity according to claim 11, comprising an application server implemented in a communication device in a network application server.

12. A controlling entity for controlling access to shared content in a communication system, the controlling entity comprising:

obtaining means for obtaining presence information with at least one access criterion associated with an access to shared content;

receiving means for receiving an access request requesting an access to at least one part of the shared content;

verifying means for verifying the access request against the at least one access criterion; and

processing means for processing the access request based on a result of the step of verifying.

15. The controlling entity according to claim 12, comprising an application server implemented in a communication device.

16. The controlling entity according to claim 12, comprising an application server implemented in a communication device in a network application server.
