1. A method performed by a network-registered device for providing an access-requesting device with access via a multimedia-enabled network to a media resource located external to the network-registered device and controllably attached thereto, wherein the method comprises the following steps:

  • determining resource capability information indicating a capability of the attached external media resource;

    transforming the resource capability information of the attached external media resource into service capability information indicating a capability related to a service accessible at the network-registered device via the network, said transforming step including;

    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.
