Title:
MULTIMEDIA SWITCHING SYSTEM
Document Type and Number:
WIPO Patent Application WO1998037664
Kind Code:
A3
Abstract:
A communications network arranged to provide multimedia switched services comprising a set of media components. The set of media components including IP traffic is encapsulated in an ATM virtual circuit and is switched as an entity using a robust signalling system so that the resultant connection records can then be employed for usage based tariffing purposes. This overcomes the problem of establishing billing records for connectionless traffic carried over a connection oriented network.
