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.
