providing a mapping table configured to map the resource capability information to the service capability information; and
determining the service capability information based on the mapping table;
providing the service capability information to at least one of the network and the access-requesting device, wherein the network-registered device comprises at least one user agent, wherein the at least one user agent is configured to;
handle the service accessible at the network-registered device; and
send the service capability information to the network or access-requesting device in a header of a network message during a registration procedure of the user agent in the network;
receiving from the access-requesting device via the network, a service request referencing the service capability information, wherein any of the at least one user agent, in response to receiving the service request, initiates establishment of the service accessible at the network-registered device;
determining the attached external media resource based on the referenced service capability information received in the service request;
accessing the determined attached external media resource;
receiving media data generated by the media resource;
aggregating the media data of the media resource with media data of further sources when connected; and
forwarding the media data to the network.

5. A method performed by a service registration server of a multimedia-enabled network for providing an access-requesting device with access via the multimedia-enabled network to a media resource located external to a network-registered device and controllably attached thereto, wherein the method comprises the following steps:
-
receiving from at least one user agent at the network-registered device, service capability information indicating a capability of a service accessible at the network-registered device via the network, wherein the service capability information has been generated by the network-registered device by transforming resource capability information of the attached external media resource into the service capability information utilizing a mapping table, wherein the service capability information is received in a header of a network message during a registration procedure of the user agent in the network; storing service registration information, wherein the service registration information comprises the service capability information and associated information for identifying the network-registered device; providing the service registration information to the access-requesting device; routing a service request from the access-requesting device toward the network-registered device based on the service registration information, the service request including the service capability information, which enables the network-registered device to identify and access the attached external media resource, receive media data generated by the attached external media resource, and forward the media data to the network; receiving a service initiation request from the network-registered device for the service accessible at the network registered device; and establishing the service accessible at the network registered device; wherein when further media resources are connected to the network-registered device, the service registration server receives aggregated media data from the network-registered device, the aggregated media data comprising the media data generated by the attached external media resource and media data from the further media sources. - View Dependent Claims (6)
