Method and a system for providing fix-line local numbers to mobile roaming subscribers
First Claim
1. A visitor service node for managing communication with roaming subscribers, said visitor service node comprising:
- a connection for receiving calls with fixed line numbers from a fixed line network;
a matching module for bringing about a match between a fixed-line number preassigned to a roaming subscriber and a universal identification of said roaming subscriber;
a querying module, associated with said matching module, configured for querying the home network of said roaming subscriber to determine a current roaming location thereof; and
a routing module configured for routing a call designating said fixed-line number to said roaming subscriber according to said current roaming location.

Abstract
A unit, for example a visitor service node manages communication with roaming subscribers to cellular networks. The visitor service node is associated with a fixed line network and assigns a fixed-line number to a universal identification of the roaming subscriber. The unit further comprises a querying module, which responds to calls made to the fixed line network using the assigned fixed line number by recognizing that the number is assigned to a roaming cellular telephone and queries the home network of the roaming subscriber regarding its current roaming location. The query is used to locate the roamer who may be connected to any cellular network, and connect the call. As a result it is possible to provide a roaming user with a single local number which can be used irrespective of which cellular network he is currently roaming in.
