ROUTING OF CALLS TO SUBSCRIBERS OF OTHER MOBILE NETWORK OPERATORS
First Claim
1. A method for routing a communication call from a first telecommunication system of a first network operator to a second telecommunication system of a second network operator;
- the first telecommunication system and the second telecommunication system being interconnected via at least two points of interconnect, POI, physically distant from each other;
the method comprising the steps of;
receiving at the first telecommunication system a setup request associated with the communication call from an originating user equipment;
determining whether a recipient of the communication call is a subscriber of the second network operator;
and if so, determining a geographical location of the originating user equipment;
selecting a POI being closest to the geographical location of the originating user equipment; and
routing the communication call from the first telecommunication system to the selected POI of the second telecommunication system.

Abstract
A method, control node, and system for routing communication calls from a first telecommunication system of a first network operator to a second telecommunication system of a second network operator, the first telecommunication system and the second telecommunication system being interconnected via at least two points of interconnect, and the points of interconnect being physically distant to each other. The method comprises the steps of receiving at the first telecommunication system a setup request associated with the communication call from an originating user equipment, determining whether a recipient of the communication call is a subscriber of the second network operator and if so, determining a geographical location of the originating user equipment, selecting a point of interconnect being closest to the geographical location of the originating user equipment, and routing the communication call from the first telecommunication system to the selected point of interconnect of the second telecommunication system.
