Abstract

An end-to-end call identifier (EECID) is provided to uniquely identify a call leg across a packet network, regardless of the number of nodes used in completing the network path. The EECID allows for call association with a bearer connection so that high level call processing and low level bearer connection management can function independently but correlated by media gateways (309, 310, 414, 415) and media gateway controllers (301, 302, 401, 402).
Either a media gateway or media gateway controller can generate (502, 603) the EECID before establishing (504, 505, 604) a connection for a call. The EECID is then sent (503, 603, 604) to remote media gateways and media gateway controllers. The bearer connection can be setup by a media gateway at either end of the connection with respect to where the EECID is generated. The invention is useful in a connection oriented packet network that is connected to a TDM telephone network through a media gateway controlled by a media gateway controller.
