Abstract

The invention relates to a switched network for use in a telecommunications network comprising a plurality of networks. The switched network has at least one switch for routing traffic to a required destination via another network according to a routing table. The switched network has call routing data management means including: means for monitoring a plurality of parameters associated with the other networks in the telecommunications network; means for determining a routing table for each switch in said network based on the monitored parameters; and, means for controlling the switch or switches according to the determined routing table.

Dependent claims

A switched telecommunications network connected to a plurality of carrier networks, said switched network having at least one switch for routing a call to a desired destination via a selected carrier network according to a routing table in each switch, wherein said switched network has call routing data management means comprising:

means in the switched network for monitoring a plurality of operational performance parameters for each of the carrier networks;
means in the switched network for automatically determining a routing table for each switch in the switched network based, at least in part, on the monitored operational performance parameters of the carrier networks;
means in the switched network for determining that a monitored operational performance parameter for one of the carrier networks has changed;
means in the switched network for automatically updating the routing table in each switch upon determining that a monitored operational performance parameter for one of the carder networks has changed;
and
means for selecting a carrier network and controlling each switch according to each switch's determined routing table to route the call to the selected carrier network based, at least in part, on the monitored operational performance parameters of the carrier networks.

3 more elements

A method of routing calls in a switched telecommunications network connected to a plurality of carrier networks, wherein said switched network includes at least one switch for routing a call to a desired destination via a selected carrier network according to a routing table in each switch, the method comprising the steps of:

monitoring by a network manager in the switched network, a plurality of operational performance parameters for each of the carrier networks;
automatically determining by the network manager, a routing table for each switch in the switched network based, at least in part, on the monitored operational performance parameters of the carrier networks;
determining by the call routing data manager, that a monitored operational performance parameter for one of the carrier networks has changed;
automatically updating by the call routing data manager, the routing table in each respective switch in accordance with a loading schedule;
and
controlling each switch according to each switch's determined routing table to route the call to a selected carrier network based, at least in part, on the monitored operational performance parameters of the carrier networks.
