This European Telecommunication Standard (ETS) has been produced by the Network Aspects (NA)
Technical Committee of the European Telecommunications Standards Institute (ETSI).
Transposition dates
Date of adoption: 19 September 1997
Date of latest announcement of this ETS (doa): 31 December 1997

Introduction
Universal Personal Telecommunication (UPT) is a new service concept, aiming to provide personal
mobility and a customized service through all the networks. UPT has to be provided taking into account
the various network architectures, e.g. the Intelligent Network (IN).
In analogy with CCITT Recommendation I.130, the first stage of the following three level structure is used
to describe the telecommunications service as provided by European public telecommunications
operators.
- Stage 1 is an overall service description, from the service subscriber's and user's standpoint;
- stage 2 identifies the functional capabilities and information flows needed to support the service
described in stage 1; and
- stage 3 defines the signalling system protocols and switching functions needed to implement the
service described in stage 1.
This ETS details the stage 1 aspects (overall service description) for the UPT service, taking into account
the various network architectures, e.g. the Intelligent Network (IN).
The application of stage 2 and stage 3 may be different when the service is supported on an Intelligent
Network (IN) environment.
The work on specification of standards has been arranged to correspond with the implementation phases
of UPT which may be split into the following general phases:
- Phase 1: restricted UPT service scenario
The restricted UPT scenario has restrictions arising from the scope of the UPT specifications in
relation to networks, services, security and user-friendliness. For this scenario, only a restricted
number of features are specified and only Public Switched Telephone Network (PSTN) and
Integrated Services Digital Network (ISDN) are considered for UPT provision.
- Phase 2: basic UPT service scenario
For the basic UPT scenario, more features are specified (e.g. registration for outgoing calls), the
supporting networks include also mobile network and data network, and advanced security is
foreseen (e.g. use of chip cards).

ETS 300 779: October 1997
- Phase 3: enhanced UPT service scenario
This scenario is also indicated as long-term scenario, where a wide set of core features are
provided, the support on other networks still not considered is granted and terminals at fixed
networks include specific UPT functions.

1 Scope
This European Telecommunication Standard (ETS) provides general guidelines to present UPT Phase 1.
The service description is related primarily to the service subscriber's and user's point of view, but does
not deal with the details of human interface itself. This ETS includes information applicable to network
operators, service providers and terminal, switch and database manufacturers.
This ETS specifies the requirements where the service is provided to the user via a telecommunications
network that is either the Pan-European Integrated Services Digital Network (ISDN) or a Public Switched
Telephone Network (PSTN) as provided by European public telecommunications operators.
The requirements different from those of the basic call where the UPT service is provided to the user via a
mobile network are outside of the scope of this ETS.
This ETS contains the core requirements for the UPT Phase 1 service, where it is provided a service that
includes a subset of core and optional features foreseen in a long-term perspective.
This ETS also describes some additional requirements which may be implemented.
Furthermore, additional functionality not documented in this ETS may be implemented. This additional
functionality may be on a network-wide basis, or particular to one or a group of users. Such additional
functionality does not compromise conformance to the core requirements of the service.
Charging principles are outside the scope of this ETS, unless specific service indications are given.
Interaction with services/supplementary services not listed in clauses 7 and 8 are outside the scope of
this ETS.
UPT enables access to telecommunication services while allowing personal mobility. It enables each UPT
user to participate in a user-defined set of subscribed services and to initiate and receive calls on the
basis of a personal, network-transparent UPT number across multiple networks on any fixed or mobile
terminal, irrespective of geographical location, limited only by terminal and network capabilities and
restrictions imposed by the network operator. Calls to UPT users may also be made by non-UPT users.
Access rights of the terminal owner may be guaranteed also in the case of registered UPT user on the
same terminal.
UPT Phase 1 service is applicable to voice telecommunication services provided by ISDNs and PSTNs.
No method of testing is provided for this ETS.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of this ETS, the following definitions apply:
calling user: Entity which originates a call to the service.
core service feature: See CCITT Recommendation Q.1290 [1].
destination user: Entity to which calls are directed.
network operator: Entity which provides the network operating elements and resources for the execution
of the UPT service.
optional service feature: See CCITT Recommendation Q.1290 [1].
personal mobility: The ability of a user to access telecommunication services at any network and
terminal on the basis of a unique personal identifier, and the capability of the network to provide those
services according to the user's service profile.
NOTE 4: Clearly personal mobility may be limited by terminal and network capabilities. This is
an alignment with the concept introduced in CCITT Recommendation I.114 [5].
Personal User Identity (PUI): The identity by which a user is known to the UPT service providers and
networks supporting UPT, and is used for flexibility and security purposes. The PUI identifies a UPT user
unambiguously. The PUI does not need to be known by users (except in case of manual procedure) or to
third parties.
service feature: See CCITT Recommendation Q.1290 [1].
service: See CCITT Recommendation Q.1290 [1].
subscriber profile: A personalized data record, for each subscriber, detailing the services and listing the
UPT users, set up between the UPT subscriber and a UPT service provider. This data is used for billing
the UPT subscriber and is used by the UPT service provider.
NOTE 5: Normally, the UPT service profile has a one to one correspondence with the subscriber
profile. However, one subscriber profile may relate to many UPT service profiles.
UPT number: Uniquely and unambiguously identifies each UPT user. It is used by a calling party to reach
the UPT user. This number is independent of terminal, network or service used and shall conform to
ITU-T Recommendation E.168 [7].
UPT service profile: A personalized data record, for each UPT user, set up between the UPT subscriber
and a UPT service provider. The UPT service profile contains a list of the services/service features and
facilities subscribed to, and a wide range of options. It is used to provide the UPT user with the UPT
service.

SIST ETS 300 779 E1:2003
Page 9
ETS 300 779: October 1997
UPT service profiles may be added or amended, when required, by agreement between the UPT
subscriber and the UPT service provider. Both parties may make use of the data during the subscription.
UPT service provider: Entity which has overall responsibility on service operation and on database
management. The UPT service provider commercially manages the service.
Specifically, the UPT service provider distributes UPT numbers and secret information to UPT subscribers
and make arrangements for provision of the UPT service to the UPT user. It also manages the billing
arrangements.
The service provider identification is provided in the Personal User Identity (PUI).
UPT service subscriber: A person or legal entity with a contractual relationship with a UPT service
provider, on behalf of one or more UPT users, responsible for the payment of charges due to that service
provider.
NOTE 1: This corresponds to the term UPT customer as used in CCITT
Recommendation I.114 [5].
UPT user: A person who has been authorized by a UPT subscriber to use UPT facilities. The UPT user is
associated with a unique UPT number.
NOTE 2: This is a special case of the definition of user introduced in CCITT
Recommendation I.112 [4].
NOTE 3: Normally, the UPT user is identical to the UPT subscriber. However, the UPT
subscriber may be a legal body mapped into many UPT users (e.g. UPT users
belonging to a company where the subscription is with the company).
3.2 Abbreviations
For the purposes of this ETS, the following abbreviations apply:
ARA Access Registration Address
CLI Calling Line Identity
IN Intelligent Network
ISDN Integrated Services Digital Network
PIN Personal Identification Number
PSTN Public Switched Telephone Network
PUI Personal User Identity
UPT Universal Personal Telecommunication
4 Description
UPT enables access to telecommunication services while allowing personal mobility. It enables each UPT
user to participate in a user-defined set of subscribed services and to initiate and receive calls on the
basis of a personal, network-transparent UPT number across multiple networks on any fixed or mobile
terminal, irrespective of geographical location, limited only by terminal and network capabilities and
restrictions imposed by the network operator. Calls to UPT users may also be made by non-UPT users.
4.1 Core requirements
This subclause supplies the core requirements applying to the core service features, as defined in
CCITT Recommendation Q.1290 [1], a service feature fundamental to the service, i.e. in the absence of
the feature, the service is not a viable service offering.

SIST ETS 300 779 E1:2003
Page 10
ETS 300 779: October 1997
The restricted UPT service scenario (Phase 1) includes the following UPT core requirements:
Incall registration (registration for incoming calls):
Incall registration enables a UPT user to register from the current terminal access. This allows
incoming UPT calls to be presented to that terminal access. When registered, all incoming calls to
the UPT user are presented to the registered terminal access for the duration specified by the
UPT user, or until a specified deregistration time. A UPT user's Incall registration shall cancel the
previous Incall registration of that UPT user. Several UPT users may simultaneously be registered
for incoming calls to the same terminal access. The UPT user may also explicitly deregister for
incoming calls.
Remote Incall registration:
Remote Incall registration enables a UPT user to register from any terminal access. This allows
incoming UPT calls to be presented to any specified terminal access.
UPT user identity authentication:
UPT user identity authentication enables the UPT service provider to verify that the identity of the
UPT user is the one claimed. This feature may be used in most UPT procedures.
Direct outgoing UPT call:
Direct outgoing UPT call enables a UPT user to initiate, from any terminal access, a single outgoing
UPT call which is charged to the UPT subscriber. This procedure includes authentication, which is
valid for one call attempt only, and the authentication procedure has to be repeated for each
outgoing UPT call attempt, except if an outcall follow-on is requested. Direct outgoing UPT calls can
be made irrespective of any previous registrations by the UPT user.
UPT service profile interrogation:
UPT service profile interrogation enables the UPT user to interrogate the current status of the
UPT user's own UPT service profile (e.g. for location information, availability of services etc.).
NOTE 1: No automatic procedure for UPT service profile interrogation is standardized in
UPT Phase 1.
UPT service profile modification:
UPT service profile modification enables the UPT user to modify the UPT user's own UPT service
profile (e.g. for change of password, change of default UPT service profile parameters etc.).
NOTE 2: No automatic procedure for UPT service profile modification is standardized in
UPT Phase 1.
Global follow-on:
Global follow-on enables a UPT user, when terminating a UPT procedure for which he has carried
out a successful authentication procedure, before disconnecting completely, to indicate a global
follow-on activity. This allows further UPT procedures without further authentication.
Outcall follow-on:
Outcall follow-on enables a UPT user, when terminating an outgoing UPT call, before disconnecting
completely, to indicate that another outgoing UPT call is to follow, without the need for further
authentication or the use of the global follow-on feature.
UPT-specific indications:
UPT-specific indications enables a set of UPT-specific user-friendly standard announcements or
indications (e.g. for support of specific charging arrangements) to be provided to the UPT users.

ETS 300 779: October 1997
Flexible allocation of call charges:
Flexible allocation of call charges enables a UPT user to specify the part of the call charges
applying to the calling user and/or the service subscriber, e.g. regular charging or split charging.
The charging mechanism is decided at subscription time.
4.2 Optional requirements
The optional requirements contain functionalities additional to the core requirements, that customize the
service according to specific service subscriber's needs. These
