  • the invention relates to a method for automatic differentiation of selected services, such as lower call tariffs , based on the geographic location of the individual terminals in the network.

The actual charging is controlled by an intelligent network. The individual home zones are established globally in the network and are thus accessible to all of the subscribers of the network. According to this system it is however not possible to alter the size of the home zones in relation to the individual users.
  • WO 97/13387 discloses how to establish home zones for individual subscribers in a cellular radio network by having the subscriber make a number of calls to a predetermined number through a terminal from different locations in the coverage area of the network.
  • the cells in the radio network to whose base stations the subscriber is linked during the registration phase, define the allocated home zone.

  • a method of the above type is according to the invention characterised in that a user of the terminal establishes an anchoring element for a geographically defined area in the cellular radio network by making a number of calls to the intelligent network, a number of neighbouring elements being allocated to the established anchoring element and the number of allocated neighbouring elements subsequently being adjusted continuously by the intelligent network based on the call and handover statistics of each terminal.
  • a method for automatically allocating selected services to specific terminals in the cellular radio network by means of an intelligent network which is able to allocate home zones to the users of specific terminals based on a statistical processing of a number of registration calls and which is furthermore able to maintain and update said home zone continuously based on ordinary calls and handovers subsequently taking place between the individual terminal and the cells in the radio network.
  • the invention also relates to a system for automatic, geographically defined, individual differentiation of selected services for specific terminals in a cellular radio network
  • an automatic service centre comprising an intelligent network which is able to communicate with a user of a terminal optionally via a recorded announcement machine provided between the terminal and the intelligent network, said intelligent network comprising at least one register for registering the individual calls from the user of the terminal and a database provided with a number of additional registers corresponding to the number of cells in the cellular radio network

  • the base stations in turn communicate with one or more so-called mobile switching centres. These mobile switching centres distribute the signal traffic to and from the individual terminals operating in the radio network, and distribute the signal traffic to and from the public service telephone network.
  • Each mobile terminal in the cellular radio network is able to communicate with one radio cell tower at a time, but a call may be handed over from one radio cell tower to another tower in the network, eg if the terminal moves to another location in the network.
  • Each mobile switching centre communicates with an operation and maintenance centre handling the overall monitoring of the cellular radio network.

  • Cells ie transmission towers, which are able to communicate with both types of terminals, are called congruent cells.
  • Three different types of terminals may be used in the network: GSM900 terminals using the 900 MHz band, GSM 1800 terminals using the 1800 MHz band or GSM900 and GSM 1800 terminals (so-called dual-band terminals).

  • the intelligent network makes use of a simple calculation of an average value based on data concerning the number of calls from a subscriber to each element collected for instance during one week and divided by the number of days between each time of collection. The above calculation indicates how much the subscriber uses the neighbouring or anchoring element.

Abstract

Dans le cadre du fonctionnement d'un réseau téléphonique cellulaire, il est souhaitable d'offrir divers services à un client tels qu'un tarif moins cher pour les appels, qui ne peut être utilisé que dans une zone locale limitée. La présente invention concerne un procédé et un système dans lesquels un client se voit attribuer au départ, une zone géographique limitée appelée zone locale, ladite zone comprenant une cellule (A) dite de base et un nombre de cellules voisines (B, C, D, E, F, G) en fonction du nombre d'appels effectués par le client via un terminal (10) vers un centre de commutation automatique, ceci définissant la zone locale sur la base d'un nombre additionnel d'appels standards suivants effectués par le client. L'administration de la zone locale du client est effectuée de manière dynamique et intelligente par un réseau intelligent (2) qui entre autres considère l'état de la transmission, la position géographique du client et les éventuels changements du réseau téléphonique cellulaire lui-même.
