Patent ID: 8195147

Claim:
A method of enabling a combinational service in a communication network wherein a plurality of terminals operate, comprising: establishing a first plurality of connections toward the plurality of terminals based on first identifiers, wherein the first identifiers identify the respective terminals in a first network; providing a management entity with the first identifiers; receiving a request to establish a second plurality of connections toward selected terminals in a second network, wherein the request includes a session identifier; verifying, by the management entity, that the selected terminals are included in said plurality of terminals, based on a determination that the session identifier identifies the first plurality of connections; providing the management entity with second identifiers of the selected terminals, wherein the second identifiers identify the respective terminals in the second network; for each second identifier, identifying, from the first identifiers provided to the management entity, a first identifier that identifies a same terminal that is identified by the respective second identifier; associating the second identifiers and the respective identified first identifiers with the combinational service; providing to the selected terminals a third identifier of the management entity in the second network; establishing, by means of the management entity, a second plurality of connections toward said selected terminals by employing the second identifiers of the selected terminals and the third identifier of the management entity; and granting an authorization to transmit information in the second network, by the management entity, to one of the selected terminals upon receiving multiple transmission requests from the selected terminals.
