Telecommunications network

DETAILED DESCRIPTION An object of the invention is to provide a telecommunications network in which the above described drawback of the known networks is alleviated or entirely eliminated.
This is achieved by means of a telecommunications network of the type described in the first paragraph of this specification, which network is according to the invention characterized in that: the telecommunications network additionally comprises subscriber numbers directly indicating the point of the network to which a call will be routed, without an interrogation to said at least one subscriber data base, the exchanges of the telecommunications network analyze the subscriber number related to an incoming call and, on the basis of the analysis, either route the call directly to the point of the network indicated by the subscriber number or make an interrogation to a data base.
In the invention, incoming calls to subscribers having a most likely access point (a low mobility) are processed in a different manner in comparison with the processing of incoming calls to subscribers not having a most likely access point (because of having a high mobility).
The calls addressed to a subscriber having a most likely access point are routed directly to the respective most likely access point of the subscriber instead of making register interrogations.
As to the calls coming to a subscriber not having a most likely access point, register interrogations are made at first, and subsequently, the call is routed to the subscriber on the basis of the roaming number of the subscriber.
In the telecommunications network according to the invention, the subscribers are distinguished from each other on the basis of information included in the subscriber numbers.
The subscriber numbers of the subscribers having a high mobility do not contain any immediate information of as to the actual location of the respective subscriber, and no indication of any predetermined access point in the network, and require an interrogation to subscriber data bases before a call can be routed forward
