DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to an arrangement in a telecommunications system which operates with the personal telephony function, here called UPT, where a user has the possibility of controlling/requesting offered personal telecommunications services and where, in the system, a unique identity, the so-called personal telephone number, here called UPTN, represents the user. The identity can be used for identifying and checking the authenticity/authenticating the user in the system.
Discussion of the Background
A flexible telecommunications system which combines functions of a wire-connected system and a mobile or cordless system is already known from Patent Specification WO 93/18606. The wire-connected network which is described in the document has the capability of receiving incoming telephone calls at an arbitrary location with the aid of central control. A subscriber belonging to a system which is described in the document has the capability of automatically registering himself with the wire-connected network with the aid of a cordless telephone. When the subscriber comes into the coverage area of a base unit, this automatically sends a registration signal to a central control unit. The system which is described in the document thus keeps a check on where a certain subscriber is located and the subscriber can select whether he wants to receive the call via the wire-connected network or the cellular network.
From American Patent Specification U.S. Pat. No. 5,077,790, a method for registering cordless telephones is already known. The system is assumed to contain a network control unit which contains, inter alia, a data base which stores the ID number of the telephones belonging to the system. Briefly, registration takes place in such a manner that the portable unit sends a registration signal which contains its ID number to the control unit via a base unit. The control unit responds to this request by sending an encrypted subscriber identity number to the portable unit if its ID number is found in the data base.
In American Patent Specification U.S. Pat. No. 4,833,704, a telephone system is shown which is divided into a number of service areas, each of which is connected to a wire-connected system. A subscriber belonging to a service area can move to another service area and automatically register himself in the new area via his cordless telephone in order to be able to send and receive calls in this area.
From European Patent Specification EP 546,467, a telecommunications system is known which combines a cordless system with a wire-connected system. There is the possibility for the user to be called in the wire-connected system via his personal telephone number in the cordless system. For the telecommunications system to be able to handle terminals in the wire-connected system as substitute for a cordless terminal, information about whether the position of the cordless terminal is picked up in the HLR is utilized.
It is thus already known to combine in different ways wire-connected telecommunications systems with some type of cordless system which is not constituted by DECT (Digital European Cordless Telecommunication).
There is a need for automatically obtaining UPT registration of a DECT portable. The UPT (Universal Personal Telecommunication) service is based on intelligence being introduced into the network through data bases so that the user can be provided with a personal number, that is to say the so-called UPT number UPTN. UPT is represented by a number of functions which make it possible for the user to control the personal telecommunications services in a uniform and flexible manner independently of which terminal, which network or which type of access is used for the occasion.
In the network, the user is represented by a unique identity, the personal telephone number, UPTN. The identity is used in identifying/authenticating a user, which ensures that operators, subscribers and end users are guaranteed a safe and reliable service.
