Abstract

A technique for accessing a media resource (114) controllably attachable to a network-registered device (104) via a multimedia-enabled network (102) is proposed. The technique comprises determining a resource capability information indicating a capability of the media resource; transforming the resource capability information into service capability information indicating a capability related to a service accessible at the network-registered device via the network; and providing the service capability information to an access-requesting entity (106).

Claims

1. A method for providing access via a multimedia-enabled network to a media resource controllably attachable to a network-registered device, wherein the method comprises the following steps:

determining resource capability information indicating a capability of the media resource;

transforming the resource capability information into service capability information indicating a capability related to a service accessible at the network-registered device via the network;

providing the service capability information to at least one of the network and an access-requesting entity;

receiving a service request referencing the service capability information via the network;

determining the attached media resource based on the referenced service capability information; and

accessing the media resource based on the determination.

2. The method according to claim 1, further comprising the following steps:

receiving media data generated by the media resource; and

forwarding the media data to the network.

3. The method according to claim 1, the step of transforming the resource capability information into the service capability information comprises the steps of

providing a mapping table, wherein the resource capability information is mapped to the service capability information;

and

determining the service capability information based on the mapping table.

4. The method according to claim 1, wherein in the step of determining the resource capability information, the resource capability information conforms to a resource description format related to the media resource;

and in the step of transforming the resource capability information into the service capability information, the service capability information conforms to a service description format of the network.

5. The method according to claim 1, wherein the network-registered device comprises at least one user agent for handling the service accessible at the network-registered device and the at least one user agent sends the service capability information to the network during a registration procedure of the user agent in the network.

6. The method according to claim 5, wherein any of the at least one user agents, in response to receiving the service request, initiates establishment of the service accessible at the network-registered device.

7. The method according to claim 1, wherein the step of sending the service capability information to the network comprises the step of sending service identification information to the network, the service identification information uniquely identifying the resource capability information which is associated to the service capability information in the network registered device.

8. The method according to claim 1, wherein in the step of sending the service capability information to the network the service capability information is included in a header of a network message sent to the network.

9. The method according to claim 2, wherein the step of receiving media data generated by the media resource comprises aggregating the media data of the media resource with media data of further sources.

10. The method according to claim 1, wherein the step of receiving the service request comprises the steps of

deciding on the service request based on decision rules;

and

providing the service based on the decision.

11. A method for providing access via a multimedia-enabled network to a media resource controllably attachable to a network-registered device, wherein the method comprises the following steps:

receiving from the network-registered device a service capability information indicating a capability of a service accessible at the network registered device via the network, wherein the capability is related to the media resource;

storing service registration information, wherein the service registration information comprises the service capability information associated with information for identifying the network-registered device;

providing the service registration information to an access-requesting entity; and

routing a service request toward the network-registered device based on the service registration information.

12. The method according to claim 11, wherein the step of receiving the service capability information comprises the steps of

receiving a service identification information from the network-registered device, the service identification information uniquely identifying a resource capability information which is associated to the service capability information in the network-registered device;

and

storing the service identification information associated with the service capability information in the service registration information.

13. A method for providing access of an access-requesting entity via a multimedia-enabled network to a media resource controllably attachable to a network-registered device, the method comprising the following steps:

determining a service capability information indicating a capability of a service accessible at the network-registered device via the network, wherein the capability is related to the media resource;

sending a service request via the network to the network-registered device, the service request referencing the service capability information, wherein the step of determining the service capability information comprises

determining a service identification information identifying a resource capability information which is associated to the service capability information in the network registered device.

14. The method according to claim 13, wherein the step of determining the service capability information comprises discovering a service registration information provided by the network, and the service registration information comprises the service capability information associate with information for identifying the network-registered device.

15. The method according to claim 13, wherein in the step of sending the service request at least one of the service capability Information and the service Identification information is included in a header of a network message representing the service request.

16-17. -17. (canceled)

18. A network-registered device for providing access via a multimedia-enabled network to a media resource;

controllably attachable to the network-registered device, wherein the network registered device comprises;
