Publish/subscribe network enabled for multimedia signaling control, method for initiating a session within the network and respective network device

A publish/subscribe network enabled for multimedia signaling control, the publish/subscribe network comprising at least two devices, each of the two devices including a user interface and a media endpoint for initiating and performing a session, wherein:

• the at least two devices provide signaling between respective user interfaces and respective media endpoints of each of the at least two devices for initiating the session;
• and
• the publish/subscribe network utilizes topics for initiating and performing the session between the at least two devices, the topics including at least a topic Party representing one of the user interfaces, a topic MediaEndpoint representing one of the media endpoints, a topic MediaEndpointRequest used in order to request any one media endpoint to join in a session for a particular one of the user interfaces, and a topic MediaEndpoint-Party Link for associating a particular media endpoint in the session for a particular one of the user interfaces.

A first device in a publish/subscribe network, the first device comprising a user interface and a media endpoint, wherein, when the first device starts up the user interface, the user interface publishes a topic, the topic including an address-identifier identifying a second user interface of a second device in the publish/subscribe network to trigger a request to start a session;

• and
• the media endpoint of the first device is started up by publishing the media endpoint to the publish/subscribe network by using a topic for the media endpoint representing the media endpoint and describing the capabilities of the media endpoint linking the media endpoint with a second media endpoint of a second user interface of a second device, after it is determined that the second user interface has accepted the session.
