Foreword
This European Telecommunication Standard (ETS) has been produced by the Network Aspects (NA)
Technical Committee of the European Telecommunications Standards Institute (ETSI).
In analogy with CCITT Recommendation I.130 (refer to annex A), 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 stand-point;
- 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 Premium Rate (PRM) service,
taking into account the various network architectures, e.g. Intelligent Network (IN).
The application of stage 2 and stage 3 may be different when the service is supported on an IN
environment.

1 Scope
General
This European Telecommunication Standard (ETS) defines the stage 1 description of the Premium Rate
(PRM) service.
NOTE: The Commission of the European Community refers to this service as the "Kiosk
Billing" service.
Stage 1 is an overall service description, primarily from the service subscribers and users point of view,
but does not deal at all with the details of the 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 any other Public
Switched Telephone Network (PSTN) as provided by European public telecommunications operators.
The requirements different from those of the basic call where the Premium Rate (PRM) service is
provided to the user via a mobile network are outside the scope of this ETS. However, if calls to the PRM
service originate or terminate in a mobile network and any special procedure above those for the basic
calls has to be performed, this should be stated in subclause 7.1 dealing with the interworking between
ISDNs, PSTNs and mobile networks.
This ETS contains the core requirements for the PRM service which are sufficient to provide a complete
service.
This ETS also documents some additional requirements which can be implemented (but do not have to be
implemented).
Furthermore, additional functionalities not documented in this ETS may be implemented. The
requirements of additional features which are considered outside the scope of this ETS and consequently
outside the scope of the corresponding stage 2 and stage 3 standards. This additional functionality may
be on a network-wide basis, or particular to one or a group of users. Such additional functionality shall not
compromise conformance to the core requirements of the service.
Charging principles are outside the scope of this ETS, unless specific service requirements are stated.
These requirements deal with the allocation of certain call charges to particular users.
Interactions with services/supplementary services not listed in clauses 8 and 9 are outside the scope of
this ETS.
Interactions between optional PRM service features and ISDN supplementary services are outside the
scope of this ETS, unless specific indication is given.
Definition and applicability
The PRM service allows a service subscriber to provide value added services to calling users. From the
user's point of view, the PRM service is the value added service offered by the service subscriber. The
calling user pays a premium rate for this call and this revenue is collected by the service provider/network
operator. The generated revenue is partially transferred to the service subscriber. The calling user should
be made aware of the charge rate to be applied to the service, however the methods used to supply
charging information are outside the scope of this ETS.
The PRM service is applicable to all telecommunications services using the CCITT Recommendation
E.164 [2] numbering plan.
If this ETS is applicable to the stage 2 and stage 3 standards for the PRM service, where the text
indicates the status of a requirement (as strict command or prohibition, as authorization leaving freedom,
as a capability or a possibility), this shall be reflected in the relevant stage 2 and stage 3 standards.
Otherwise, the status of a requirement shall be reflected in the relevant standards for the underlying
protocols.

ETS 300 712: March 1997
Furthermore, conformance to this ETS is either met by:
- conforming to the stage 3 standards; or
- implicitly covered by conforming to the standards for the underlying protocols;
with the field of application appropriate to the equipment being implemented. Therefore no method of
testing is provided for this ETS.
2 Normative references
This ETS incorporates by dated or undated reference, provision from other publications. These normative
references are cited at the appropriate places in the text and the publications are listed hereafter. For
dated references, subsequent amendments or revisions of any of these publications apply to this ETS only
when incorporated in it by amendments or revision. For undated references, the latest edition of the
publication referred to applies.
[1] ETS 300 345 (1994): "Integrated Services Digital Network (ISDN); Interworking
between public ISDNs and private ISDNs for the provision of telecommunication
services; General aspects".
[2] CCITT Recommendation E.164 (1991): "Numbering plan for the ISDN era".
3 Definitions
For the purposes of this ETS, the following definitions apply:
calling user: Entity which originates a call to the PRM service.
catchment area: The area from which the service subscriber has agreed to receive premium rate calls.
core service feature: Particular service feature fundamental to the telecommunication service, i.e. in the
absence of this service feature, the telecommunication service does not make sense as a commercial
offering to the service subscriber.
customer: Service subscriber.
destination user: Entity to which PRM calls are directed.
network operator: Entity which provides the network operating elements and resources for the execution
of the PRM service.
non-running record: A record containing the service subscriber profile parameters used by the service
and currently not in operation.
optional service feature: Service feature added to core feature to optionally enhance a service offering.

---------------------- Page: 10 ----------------------

ETS 300 712: March 1997
premium rate number: Set of digits constituted of two parts and forming the national part of a CCITT
Recommendation E.164 [2] number. The first part is a set of digits identifying the PRM service and
forming the national destination code part. The second part is a set of digits assigned by the service
provider to a service subscriber at subscription, identifying this specific service subscriber and forming the
subscriber number part.
NOTE: Due to regulatory aspects, it may be necessary to offer several classes of premium
rate services which should be identified by different national destination codes.
running record: A record containing the service subscriber profile parameters used by the service and
currently in operation.
service feature: Specific aspect of a telecommunication service that can also be used in conjunction with
other telecommunication services or service features as part of a commercial offering. It is either a core
part of a telecommunication service or an optional part offered as an enhancement to a
telecommunication service.
service provider: Entity which offers the PRM service for service subscription. The network operator may
be the service provider.
service subscriber profile: Service subscriber related data needed by the service in order to handle the
calls.
service subscriber: Entity which subscribes to the PRM service, i.e. who provides a value-added service
to the calling users.
service: That which is offered by a service provider to its customers in order to satisfy a
telecommunication requirement.

5 Description
This ETS does not detail the way in which the service subscriber provides value added services (for
example information services, entertainment services, consultancy services, mail order services, etc.).
But, in order to give some examples, three basic scenarios can be envisaged:
- the use of private equipment (that may have also interactive capabilities);
- the use of network based facilities (e.g. routing features, announcement capabilities, digit collection,
information stored into the network);
- the use of private equipment in conjunction with some network based capabilities.

---------------------- Page: 11 ----------------------

SIST ETS 300 712 E1:2003
Page 10
ETS 300 712: March 1997
The last two scenarios, that allow the service subscriber to have several destinations reachable using the
same premium rate number, are not considered in the core service feature description.
5.1 Core requirements
The service provider/network operator provides the communication path between the calling user and the
service subscriber, collects the revenue generated by the call, and transfers the portion allocated to the
service subscriber.
The service subscriber provides value added services to callers (e.g. using private equipment connected
to service subscribers termination(s)).
5.2 Optional requirements
The optional requirements contain functionalities additional to the core requirements, that customize the
service according to specific service subscriber's needs. These additional parts may be offered either to
all the service provider's customers, or to a group or even to a single customer.
Some possible optional service features are listed hereafter, but the service provider may offer other
additional service features.
5.2.1 Presentation of Charging Information (PCI)
This feature enables the calling user to get a indication (e.g. an announcement) about the charges of the
tariff of the call currently placed, as part of the invoked service.
5.2.2 Call Distribution (CD)
This feature enables the service subscriber to specify the distribution mechanisms for calls to be shared
between different destinations.
NOTE 1: Distribution mechanism may be for example:
- managed according to the availability of destination users to be able to accept
the calls (see note 2);
- circular: the calls are routed to the different destinations with a uniform load;
- percentage based: the calls are routed to the different destinations according to
a percentage.
NOTE 2: This requires the call distribution service feature to be made aware of the status of the
destination users by the relevant destination networks.
5.2.3 Customer Profile Management (CPM)
This feature enables the service subscriber to manage one or several PRM service handling profiles
currently not in operation, and to control which record is running or not running.
If the service provider does not permit the subscriber to own several profiles, i.e. does not implement non-
running records, this feature may allow the service subscriber to modify the profile when in operation.
This feature also permit the modification of service parameters.
5.2.4 Customized Recorded Announcements (CRA)
This service feature enables the subscriber to specify customized terminating announcement to be played
to the calling user. Such announcements may be provided by the service provider or remote recorded by
the service subscriber.

SIST ETS 300 712 E1:2003
Page 11
ETS 300 712: March 1997
5.2.5 Originating User Prompter (OUP)
This feature enables to prompt the user to enter information to be used by the service to continue the
processing of the call.
5.2.6 Origin Dependent Routing (ODR)
This feature enables the service subscriber to split the service catchment area into different routing areas,
and to specify the routing destination(s) for each of the routing areas. The routing areas may be specified
by the service subscriber.
5.2.7 Statistical information (STAT)
This feature permits the service subscriber to obtain, from the service provider, statistical information on
calls placed to the service.
Such information may be for example daily traffic curve, traffic analysis per routing area, performance
evaluation.
5.2.8 Time Dependent Routing (TDR)
This feature enables the service subscriber to specify the routing destination(s) according to a selected
time interval. At a given point in time, an originated call should be routed to the destination as defined for
the time interval in which the given point in time matches. The time interval may be specified by the
service subscriber.
NOTE: The time interval may for instance take into account day of year, day of week, time of
day.
5.2.9 Time Dependent Control (TDC)
This feature enables the service subscriber to specify time intervals (e.g. time of day, day of week, specific
dates) that can be used to modify the handling of the call according to the point in time
...
