`ABSTRACT
`
`A telecommunications System operates with a personal
`telephony function and a respective user has the capability
`of controlling offered personal telecommunications Services.
`In the System, the user is represented by a unique identity
`(UPTN), which is used for identification and authenticity
`check of the user. Access to the telecommunications Services
`can be established from a DECT portable which is involved
`in identification, authenticity check and registration in the
`telephone system. Availability of the services offered thus
`becomes more user friendly and the services and the DECT
`System become more attractive to the end users.

`
`BACKGROUND OF THE INVENTION
`The present invention relates to an arrangement in a
`telecommunications System which operates with the per
`sonal 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 automati
`cally 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 automati
`cally 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 tele
`communications System is known which combines a cord
`leSS 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
`65
`of cordless system which is not constituted by DECT
`(Digital European Cordless Telecommunication).
`
`45
`
`50
`
`55
`
`60
`

`There is a need for automatically obtaining UPT regis
`tration 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 uni
`form 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.
`The first implementations of UPT, however, will not be
`very user-friendly. Even if work is carried out for making it
`possible to Store the identity in a Smart card and to use this
`for identification and authentication, Such a functionality
`will not be available on the market for a few years yet. In
`UPT phase 1, registration of, for example, incoming calls
`will be an almost intolerable button-pressing procedure. In
`later phases of UPT, presumably developed application
`cards will be part of the service, but even these will require
`contributions from the user. The conventional registration
`method in UPT also requires that a separate telephone call
`is set up, which entails disadvantages in the form of extra
`costs and traffic load in the network.
`
`SUMMARY OF THE INVENTION
`The problem which the present proposal intends to solve
`is found in the cumberSome procedures which are part of the
`early UPT-based services. The proposal describes how an
`automatic registration method can make DECT-access to
`UPT services more user friendly and UPT services in
`combination with DECT more attractive to the end user.
`Digital European Cordless Telecommunications, DECT,
`is a standard which has been developed in ETSI for cordless
`telecommunication within the public domain, for business
`eXchanges and for radio acceSS in the local area network. In
`the overwhelming majority of installations, the DECT sys
`tem will be linked to the public PSTN or ISDN telecom
`munications network, either through PABXs or through
`direct connections. By this means, DECT can thus offer an
`effective access to UPT for a large number of potential users.
`DECT is a very flexible standard and contains, among
`other things, a user module called DECT Authentication
`Module, or DAM card. There is also a whole battery of
`functions defined for registration, authentication,
`encryption, etc. These can be utilized for automatically
`registering the DECT subscriber for UPT services in a
`user-friendly and flexible manner.
`The fixed side of DECT consists of so-called Radio Fixed
`Parts, RFPs, and a central unit, Central Fixed Parts, CFP.
`Together, they form a Fixed Part, FP, RFPs coupled to a
`common central unit constitute a So-called “cluster' and can
`serve a coverage area (see FIG. 1). This DECT system is
`owned or administered by an operator who can be either a
`public telecommunications operator or can be privately
`owned. In the latter case, certain contracts will be needed for
`coupling to the public network.
`Each FP continuously sends out information via its
`“broadcast' channels, in the Q-channel System information,
`RFPI, for being able to, among other things, identify the
`base Station and its Service area, Location Area, LA, and in
`
`Ex.1051
`APPLE INC. / Page 5 of 9
`
`

`

`15
`
`3
`the Q or N channel, the access rights, AcceSS Rights
`Identities, ARIs are identified which a Portable Part, PP, or
`portable, needs for being able to communicate with the base.
`In more advanced applications local data bases Home
`Data Base, HDB, and Visitors Data Base, VDB, can also
`belong to the CFP of the system, but their intelligence can
`also be implemented directly in the CFP
`A PP, which has the same set of access rights, Portable
`Access Rights Key, PARK, as the FP, can communicate with
`the DECT system. As soon as the PP senses that it has
`entered a new LA it attempts to establish contact with the
`fixed Side and to carry out registration. In this proposal, this
`functionality is utilized for combining the personal mobility
`in UPT with the terminal mobility which is offered via the
`DECT technique, in a manner which is very advantageous
`for users and operators.
`The present proposal provides, among other things,
`instructions on how automatic registration of incoming and
`outgoing calls can be carried out for a DECT portable. The
`text below describes, how this registration can be carried out
`depending on what inbuilt UPT functionality is found in the
`portable.
`The invention Specifies how automatic registration of
`incoming and outgoing calls can be carried out without there
`being a need for direct call setting-up towards UPT. The
`different alternatives can be utilized independently of one
`another or alternatively determined by the UPT functionality
`which is stored in the calling DECT portable.
`The feature which can mainly be considered more con
`cretely to characterize an arrangement according to the
`invention is that access to the Said telecommunications
`services can be established from a DECT portable by means
`of which identification, authenticity check and registration
`in the telecommunications System can be effected with the
`aim of making the accessibility of the Services offered in the
`UPT function more user friendly and making the said
`telecommunications services and DECT more attractive to
`the end user.
`In one embodiment of the concept of the invention, both
`incoming and outgoing calls can be automatically registered
`with the aid of a respective DECT portable. In the
`embodiment, registration can be effected without need for
`direct call Setting-up towards UPT, even if Such call Setting
`up can be carried out for Speeding up the functions. Further
`embodiments of the concept of the invention can be found
`in the patent claims following.
`The above provides a solution which combines user
`friendliness and procedures in the DECT system with an
`automatic registration method in UPT. In this context, one
`can start from the traditional methods which consisted of the
`user himself having to initiate the call Setting-up and pro
`Viding the network with registration information. The inven
`tion also Solves the above in an all-embracing and flexible
`manner So that, generally Speaking, each DECT terminal can
`be utilized for access to UPT. The invention can be imple
`mented with network functions which will be found acces
`Sible in UPT and DECT. The invention can be used in all
`applications where the DECT System can offer a user acceSS
`to the fixed network and thus to UPT services. The principles
`of how automatic registration is carried out are based on the
`functionality which is inherent in a DECT portable and the
`services which are offered by the operators of the DECT
`60
`System and the public telecommunications operators which
`offer a UPT personal number via the telecommunications
`network.

`FIG. 4 shows a flow chart of a second function in the
`arrangement.
`DESCRIPTION OF THE PREFERRED
`EMBODIMENTS
`In the DAM card are Stored user-specific identities, keys
`for authentication, encryption and functionality for being
`able to identify a DECT system. ADAM card for a user with
`personal number in UPT should at least be able to store
`UPTN and security codes in the form of a Personal Identi
`fication Number, PIN
`code. For security reasons, a UPT
`registration requires that the PIN code is used, but Since a
`user has already in advance authenticated himself with the
`DAM card, it is possible for this code to be stored in
`advance.
`The DAM card, however, is not obligatory. A portable can
`also be programmed in advance for Storing the same func
`tionality internally. The text below describes how the DAM
`card can be used, but the same functionality can be offered
`with a preprogrammed portable.
`When the user Switches on the terminal, a local authen
`tication occurs towards the DAM card with the aid of the
`PIN
`code. This is the personally defined acceSS code of
`the user and the only number he needs to remember. All
`further authentication towards the DECT system and back
`ground UPT occurs via an automatic arrangement built into
`the portable and the fixed DECT system.
`To be able to reach a specific DECT user, a set of
`International Portable User Identities, IPUIs, is defined.
`These identities can also be of several different types within
`the different environments where the DECT user can utilize
`his subscription(s). A combination of PARK and IPUI, an
`IPUI/PARKpair gives the DECT user a unique identity.
`For public access, ARI/PARK class C and IPUI type S are
`defined. In this solution, this is defined to contain UPT
`access according to FIG. 2. This figure is Self-descriptive.
`A portable which has analyzed the System information
`from the base and drawn the conclusion that it can be
`granted entry automatically attempts to tell the base that it is
`located within the coverage area and can thus "lock itself
`s .
`In connection with this, the user receives a request on
`whether registration towards UPT will be carried out. An
`affirmative answer, either in the form of the user acknowl
`edging a message on the display or the PP being prepro
`grammed (possibly by the user) for generating this func
`tionality itself, leads to the registration procedure being
`initiated. This is done by the PP initiating a procedure for
`Location Registration (see FIG. 2). If the user does not wish
`to register towards UPT, the active IPUI must be deactivated
`and another Stored identity must be used instead.
`1. The portable sends a message to FP with information to
`the effect that it is located within the coverage area. In the
`DAM card or in the software of the portable, the UPT
`identity is stored. This is transferred to the FP together with
`the predefined Security code PIN.
`2. The FP carries out a number analysis of the telephone
`number which has been sent via the IPUI. If the CFP
`
`Ex.1051
`APPLE INC. / Page 6 of 9
`
`

`

`15
`
`S
`identifies the content in the IPUI as a personal number in the
`UPT and it can handle a UPT registration, the DECT system
`will automatically attempt to initiate a registration procedure
`of the user with the background fixed network (FIG. 3).
`3. The PP gets the acknowledgement from the fixed side
`that the identity can be handled together with information on
`“Location area” and an alphanumeric message that UPT
`registration is occurring.
`If the FP cannot handle UPT registration or does not
`accept the portable for another reason, a negative acknowl
`edgement is sent instead. A failure leads to the fact that no
`further communication can be carried out between the units
`with this identity, that is to say UPT registration cannot be
`carried out.
`4. On reception of a positive acknowledgment, the por
`table indicates to the user that UPT registration is occurring.
`At this stage, the user can Speed up the procedure by making,
`for example, an outgoing call which directly registers the
`portable for UPT. If the user instead chooses to wait, the
`portable is not registered for incoming calls until the FP has
`been given information about it (step 5).
`5. After registration with the network has been carried out
`for one or more simultaneous portables (see below), the FP
`Sends to it/them a one-way message with alphanumeric
`information about the outcome of the registration. A positive
`acknowledgement, for example in the form of “UPT OK',
`gives the user an indication that the registration procedure
`has been Successfully carried out. A failure of registration is
`indicated, for example, by the message "UPT registration
`unsuccessful'.
`The reason for the FP not immediately updating each
`portable which makes a request is that this can lead to a
`traffic load in the network which is not desirable for the
`operator. Instead, the FP can wait for a predetermined time
`interval (for example 5 minutes) and execute the requests of
`several portables at the same time. Since the UPT registra
`tion can also be linked to a charge for the Subscriber, a
`collected registration of Several portables can be one way of
`Sharing the registration costs.
`Before the FP acknowledges that registration is carried
`out and the portable can indicate this to the user, transfer of
`the UPTN and PIN
`from CFP, updating of the databases
`in the network and transfer of roaming information, See FIG.
`3, occurs.
`A user who wishes to have his portable automatically
`registered with the UPT without having the possibility of
`Storing UPT identities needs to make an agreement about
`this with his local DECT operator in advance. The operator
`then stores the identity of the portable in his local data base
`with an indication that registration with UPT will be carried
`out. Reference is made to FIG. 4.
`When the portable enters into a new coverage area
`(Location area) and initiates a registration with the local
`DECT system, the following happens in connection with
`Location registration (see FIG. 4):
`1. A normal registration procedure is initiated towards the
`local DECT system.
`2. CFP carries out a number analysis of IPUI. If this is
`found Stored in its own data base as a user who wishes
`registration with DECT, the FP responds with information
`about the “Location area” together with an alphanumeric
`request that the user should enter the PIN code.
`An FP which does not provide access to the UPT
`65
`acknowledges the updating request of the portable in accor
`dance with normal DECT procedures.

`If the FP, on the whole, does not accept the portable which
`requests access to the System, a negative acknowledgement
`is Sent. No further communication can be carried out
`between the units which the active IPUI.

`3. The user enters his personal PIN
`transferred to the fixed side in a special message. For a user
`who does not wish to register with the UPT, a predefined
`value, for example 0, is Sent as PIN code and is recognized
`by the FP which breaks off registration with the UPT.
`However, this portable still has normal DECT access to the
`local System, including the other acceSS capabilities offered
`via this.
`4. Registration takes place. The user can wait for the
`registration or Speed it up by initiating an outgoing call
`which directly registers the portable for UPT.
`5. After registration with the network has been carried out
`for one or more portables, the FP indicates this as at point 5
`above.
`The CFP updates the portable towards the UPT in accor
`dance with the above description.
