  • Patent number: 6072866
    Abstract: In a telecommunications network which supports path replacement, an improved path replacement scheme is described for use after a supplementary service call has been carried out. The basic call and the supplementary call involve at least a basic call originating node, a diverting node and a diverted-to node of the telecommunications network. Where several methods are provided for carrying out the supplementary service, an identifier is included in one of the messages sent to the diverted-to node which identifies which method is intended for, or has been used for the supplementary service call. In response to this identifier, the diverted-to node either invokes a path replacement when the supplementary service call has been established over a non-optimum path or suppresses path replacement if the call is known to be optimum.
