Abstract
Methods and systems for extending the IMS/SIP architecture of the NGN to provide QoS service to generic bearer flows. More particularly, a method is provided for establishing an bearer end-to-end path of a communication session in a multi-domain communication network in which an out of band signalling protocol is used to establish communications sessions. The method comprises receiving an out-of-band signalling message including information representative of at least an opposite end point of a first bearer segment of the end-to-end path. The information is used to define a cross-connect mapping through a node of the network between respective local endpoints of the first bearer segment and a second bearer segment hosted by the node. Information representative of the cross-connect mapping is then inserted into the out-of-band signalling message, and the out-of-band signalling message forwarded.
