Abstract (en)
[origin: WO03028319A2] The invention relates to a method for determining the propagation delay in a packet-based network for a packet-based network section of a connection between terminals (TlnA, TlnB), at least sections of said connection being routed via the packet-based network (INT). According to the inventive method, the broadcast delay (rdly) in the packet-based network is determined for the packet-based network section of the connection and substantially half of the time period that has been determined for the broadcast delay (rdly) is taken as a value for the propagation delay (PD) of the packet-based network section. The method permits the determination of the propagation delay in the packet-based network. This parameter can help, for example, to determine whether an echo compensation is required during a voice connection.
