Method for routing calls from a terminal in a first telecommunication network to any terminal in an external telecommunication network
First Claim
1. A system for routing calls from a first terminal in a first telecommunications network to a second terminal in an external telecommunications network having a plurality of geographical regions, said system comprising:
- a plurality of gateways, each of said plurality of gateways being for routing calls from said packet network to an associated geographical region of said plurality of geographical regions of said external telecommunications network; and
a routing entity for selecting one of said plurality of gateways for routing a particular call from the first terminal in said packet network to the second terminal in said external telecommunications networkbased upon predetermined criteria, and for routing the call from the first terminal to the second terminal through the selected one of said plurality of gateways, said routing entity including a routing table containing predetermined information about the plurality of geographical regions, said predetermined information including at least a portion of telephone numbers reflecting codes for each of said plurality of geographical regions and cost levels for each of said plurality of geographical regions, and a quality of service table reflecting quality of service for each of said plurality of gateways, wherein said predetermined criteria include a criterion reflecting said codes for each of said plurality of geographical regions a criterion reflecting cost levels for each of said plurality of geographical regions, and a quality of service criterion reflecting available ports at any particular one of said plurality of gateways and whether a call is an audio call, an audio and video call or a data call.

Abstract
The present invention relates to a method for routing calls from a terminal in a first telecommunication network, for example an intranet, to any terminal in an external telecommunication network, the interworking between said networks taking place through one of several interworking units or so-called gateways (GW), and in order to provide a method which in a more effective manner can optimise such interworking between such networks, it is according to the present invention suggested that there is used at least one routing entity which routes the call or calls through a gateway (GW1, GW2) giving the most optimal route, for example the most cost effective or resource effective route.
