Abstract
In a telecommunications network having some high mobility subscribers, for which no most likely access point can be determined and the subscriber numbers of which do not include immediate information of the actual location of a subscriber, there are also some semi-fixed subscribers and/or fixed subscribers, for which it is possible to determine their most likely access point and the subscriber numbers of which indicate their most likely access point. In case of incoming calls, the first exchange to process a call in the telecommunications network routes the call on the basis of the called subscriber'"'"'s subscriber number directly to an exchange serving the subscriber'"'"'s most likely access point.
