SIST ETS 300 779 E1:2003 is the SIST version of ETS 300 779 Edition 1 from ETSI. It describes Universal Personal Telecommunication (UPT) Phase 1 as a service from the subscriber and user point of view, with its core features, optional features, procedures, interworking, and interactions with selected supplementary services. It is written for network operators, service providers, and equipment manufacturers that need to plan, implement, or support UPT on ISDN and PSTN networks.

What does SIST ETS 300 779 E1:2003 specify?

SIST ETS 300 779 E1:2003 specifies the Phase 1 service description for UPT in a restricted service scenario. It focuses on voice telecommunication services provided over the Integrated Services Digital Network (ISDN) and Public Switched Telephone Network (PSTN), and it presents the service mainly from the subscriber and user perspective.

The document is organized into these main parts:

• Scope
• Normative references
• Definitions and abbreviations
• Description
• Procedures
• Interworking requirements
• Interaction with ISDN supplementary services
• Interaction with other services
• Annex A, which is a bibliography

The scope also makes clear what the standard is not about in practice: it does not specify a test method, and it does not go into the details of the human interface. It also leaves out mobile-network-specific requirements for Phase 1.

What are the key requirements of SIST ETS 300 779 E1:2003?

SIST ETS 300 779 E1:2003 defines the core UPT functions that make Phase 1 workable, then adds optional functions and service interactions that shape how the service behaves in real networks. For implementers, the important point is that UPT is not just a number plan - it is a set of registration, authentication, call handling, and profile management behaviors.

Core service features in clause 4.1

The standard makes incall registration a core feature. A UPT user can register the current terminal access for incoming calls, and a new registration cancels the previous one for that user. In practice, this is the mechanism that lets incoming calls follow the user to a chosen access point.

It also includes remote incall registration, which allows registration from any terminal access, and UPT user identity authentication, which lets the service provider verify the claimed identity. For operators and service providers, this means access control and call routing depend on verified identity, not only on the dialed number.

The core call feature is direct outgoing UPT call. A user can place a single outgoing UPT call from any terminal access, and the call is charged to the UPT subscriber. The standard says this authentication is valid for one call attempt only unless outcall follow-on is used, so systems must be prepared to repeat authentication when needed.

The core service profile functions are UPT service profile interrogation and UPT service profile modification. These let the user check and change the active profile, such as location-related status, subscribed services, and default parameters. This matters operationally because profile data drives what the service will actually allow at the next call or registration.

Two follow-on features also belong to the core set: global follow-on and outcall follow-on. Global follow-on lets a user continue with another UPT procedure after successful authentication without repeating access, identification, and authentication. Outcall follow-on is narrower and supports another outgoing call after a call attempt without repeating those steps. These features reduce repeated logins in active use.

Optional requirements in clauses 4.2 and 4.3

The standard allows access to groups of UPT service profiles and operator-assisted services as optional functions. That is useful where a subscriber manages several users or where manual help is needed for procedures that cannot be completed automatically.

Clause 4.3 lists optional supplementary services, including UPT call forwarding unconditional, on busy, and on no reply, plus variable routeing based on time and on calling line identity. In practice, these features let the subscriber define how incoming UPT calls should be distributed and redirected under different conditions.

Procedure rules in clause 5

Clause 5 separates UPT procedures into elementary procedures, personal mobility procedures, UPT call handling procedures, and UPT service profile management procedures. The essential procedures cover access, identification, authentication, incall registration, incall deregistration, outgoing UPT call set-up, profile interrogation, profile modification, and PIN change.

A notable rule is that strong authentication is recommended, while weak authentication using a Personal Identification Number (PIN) is optional and linked to the security architecture reference. For practical deployment, that means the standard supports more than one security approach, but places stronger emphasis on authenticated access to protected functions.

Interworking rules in clause 6

UPT Phase 1 is supported between ISDNs and PSTNs without extra requirements, and it is also intended to work with private networks in a cooperative manner across the internetwork interface. Mobile-network provision is not foreseen for Phase 1. For procurement and planning, that fixes the intended network domain of this edition.

Service interactions in clauses 7 and 8

The standard gives specific interaction rules with ISDN supplementary services. For example, advice-of-charge information is not sent to the called user for incoming UPT calls, several diversion services are overridden by incoming UPT calls, and requests for completion-of-call-to-busy-subscribers and completion-of-calls-on-no-reply are rejected for calls to a UPT number.

Clause 7.5 and 7.12 also show how numbering and identification behave: the UPT number is presented or recorded in several cases, while location information is not exposed as a substitute for the UPT identity. Clause 8 adds that card calling services may coexist with UPT, but not at the same time, and that a UPT user shall not register for incoming calls on PRM numbers or televoting numbers.

What terms does SIST ETS 300 779 E1:2003 define?

• Access Registration Address (ARA) - the address used when a user specifies where incoming calls should be presented.
• Personal User Identity (PUI) - the identity used by UPT service providers and supporting networks to identify a user unambiguously.
• UPT number - the personal number that uniquely identifies a UPT user and is used by calling parties to reach that user.
• UPT service profile - the personalized record of subscribed services, options, and default parameters for one UPT user.
• UPT service subscriber - the person or legal entity that has the contract with the UPT service provider and pays the charges.
• UPT user - the person authorized by the subscriber to use UPT facilities under a unique UPT number.
• Personal mobility - the ability to access telecommunication services at any network and terminal through a unique personal identifier.
• PIN - Personal Identification Number, used here for weak authentication.

Who uses SIST ETS 300 779 E1:2003?

SIST ETS 300 779 E1:2003 is used by network operators, UPT service providers, and manufacturers of terminals, switches, and databases. These roles use it to design registration flows, authentication handling, profile management, numbering behavior, and interworking with ISDN and PSTN environments.

It is also relevant to engineers and quality managers who need to verify that a UPT implementation matches the Phase 1 service model. Buyers can use it to check whether a solution is intended for subscriber-and-user-facing UPT service support rather than for mobile-network service design.

What changed in SIST ETS 300 779 E1:2003 from the previous edition?

SIST ETS 300 779 E1:2003 corresponds to ETS 300 779 Edition 1. The Slovenian standard is identified as identical to that edition.

Which standards are used with SIST ETS 300 779 E1:2003?

The normative references give the supporting vocabulary, numbering, interworking, and security basis for UPT Phase 1:

• CCITT Recommendation Q.1290 - vocabulary for intelligent network terms, including core and optional service features.
• ETS 300 345 - general aspects of interworking between public ISDNs and private ISDNs.
• CCITT Recommendation E.164 - the numbering plan used for the ISDN era and referenced for UPT access numbering.
• CCITT Recommendation I.112 - ISDN general structure vocabulary.
• CCITT Recommendation I.114 - ISDN vocabulary for Universal Personal Telecommunication.
• ETR 191 - general principles and service aspects for PTN mobility using UPT Phase 1.
• ITU-T Recommendation E.168 - application of the E.164 numbering plan for UPT.
• ETS 300 391-1 - the UPT Phase 1 security architecture, including weak authentication by PIN.

What does the SIST ETS 300 779 E1:2003 document contain?

The document contains a service-level description of UPT Phase 1, not a test specification. It lays out the service model, the defined user and subscriber roles, the core and optional service features, and the procedures for access, registration, authentication, call set-up, and profile management.

It also gives the expected behavior when UPT meets ISDN supplementary services and other services such as card calling, premium rate, and televoting. Annex A adds a bibliography for related background documents and foundational UPT material.

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).

Page 6
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.

ETS 300 779: October 1997
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.
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).

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.

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:
Outcal
