1 Scope
This part of the Digital European Cordless Telecommunications (DECT) Common Interface specifies the
identities and addressing structure. It is Part 6 of a series of 9.
There are four categories of identities to be used for identification and addressing in a general DECT
environment. These four categories are:
- Fixed Part (FP) identities;
- Portable Part (PP) identities;
- connection-related identities;
- equipment-related identities.
Fixed part identities and portable part identities are used for:
- access information from fixed parts to portable parts;
- access requests from portable parts;
- identification of portable parts;
- identification of fixed parts and radio fixed parts;
- paging;
- billing.
These identities support:
- different environments, such as residential, public or private;
- supply to manufacturers, installers, and operators of globally unique identity elements with a
minimum of central administration;
- multiple access rights for the same portable;
- large freedom for manufacturers, installers, and operators to structure the fixed part identities, e.g.
to facilitate provision of access rights to groups of DECT systems;
- roaming agreements between DECT networks run by the same or different owners/operators;
- indication of handover domains;
- indication of location areas, i.e. paging area;
- indication of subscription areas of a public service.
This specification also provides for length indicators and other messages that can override the default
location and/or paging area and domain indications given by the structure of the identities.
Connection related identities are used to identify the protocol instances associated with a call and are used
for peer-to-peer communication.
Equipment related identities are used to identify a stolen PP and to derive a default identity coding for PP
emergency call set-up.
Page 8
ETS 300 175-6: October 1992
Coding of identity information elements for higher layer messages is found in ETS 300 175-5 [5], subclause
4.7.
User authentication and ciphering need additional key information and is not within the scope of this part,
but is covered in other Parts of ETS 300 175, e.g. Part 7.

3 Definitions and abbreviations
The definitions are listed in alphabetic order.
3.1 Definitions
For the purposes of this ETS the following definitions apply.
Attach: the process whereby a Portable Part (PP) within the coverage area of a Fixed Part (FP) to which
it has access rights, notifies this fixed part that it is operative. The reverse process is detach, which
reports the portable part as inoperative.
NOTE: An operative portable part is assumed to be ready to receive calls.
Authentication (of a subscriber): the process whereby a DECT subscriber is positively verified to be a
legitimate user of a particular fixed part.
NOTE: Authentication is generally performed at call set-up, but may also be done at any other
time (e.g. during a call).
Bearer: see Medium Access Control (MAC) bearer or bearer service.
Bearer handover: the internal handover process provided by the MAC layer, whereby one MAC
connection can modify its underlying bearers while maintaining the service provided to the Data Link
Control (DLC) layer.
NOTE: Bearer handover is slot based.
Cell: the domain served by a single antenna(e) system (including a leaky feeder) of one fixed part.
NOTE: A cell may include more than one source of radiated Radio Frequency (RF) energy (i.e.
more than one radio end point).
Page 10
ETS 300 175-6: October 1992
Central Control Fixed Part (CCFP): a physical grouping that contains the central elements of a fixed
part. A fixed part shall contain a maximum of one CCFP.
NOTE: A CCFP controls one or more Radio Fixed Parts (RFPs).
Cluster: a logical grouping of one or more cells between which bearer handover is possible. A Cluster
Control Function (CCF) controls one cluster.
NOTE: Internal handover to a cell which is not part of the same cluster can only be done by
connection handover.
Connection: see "MAC connection".
Connection handover: the internal handover process provided by the DLC layer, whereby one set of
DLC entities (C-plane and U-plane) can reroute data from one MAC connection to a second new MAC
connection, while maintaining the service provided to the network layer.
NOTE: Connection handover is DLC frame based.
Coverage area: the area over which reliable communication can be established and maintained.
DECT NetWork (DNW): a network that uses the DECT air interface to interconnect a local network to one
or more portable applications. The logical boundaries of the DECT network are defined to be at the top of
the DECT network layer.
NOTE: A DECT network is a logical grouping that contains one or more fixed radio
terminations plus their associated portable radio termination. The boundaries of the
DECT network are not physical boundaries.
External handover: the process of switching a call in progress from one fixed radio termination to another
fixed radio termination.
Fixed Part (FP): a physical grouping that contains all of the elements in the DECT network between the
local network and the DECT air interface.
NOTE: A DECT fixed part contains the logical elements of at least one fixed radio Termination,
plus additional implementation specific elements.
Fixed radio Termination (FT): a logical group of functions that contains all of the DECT processes and
procedures on the fixed side of the DECT air interface.
NOTE: A fixed radio termination only includes elements that are defined in ETS 300 175. This
includes radio transmission elements (layer 1) together with a selection of layer 2 and
layer 3 elements.
Frame: see Time Division Multiple Access (TDMA) frame or DLC frame.
Geographically unique: this term relates to fixed part identities, (PARIs and RFPIs). It indicates that two
fixed parts with the same PARI, or respectively two RFPIs with the same RFPI, can not be reached or
listened to at the same geographical position.
NOTE: PARI stands for Primary Access Rights Identifier, RFPI stands for Radio Fixed Part
Identifier.
Global NetWork (GNW): a telecommunication network capable of offering a long distance
telecommunication service.
NOTE: The term does not include legal or regulatory aspects, nor does it indicate if the
network is a public or a private network.
Page 11
ETS 300 175-6: October 1992
Globally unique (identity): the identity is unique within DECT (without geographical or other restrictions).
Handover: the process of switching a call in progress from one physical channel to another physical
channel. These processes can be internal (see internal handover) or external (see external handover).
NOTE: There are two physical forms of handover, intra-cell handover and inter-cell handover.
Intra-cell handover is always internal, inter-cell handover can be internal or external.
Inter-cell handover: the switching of a call in progress from one cell to another cell.
Internal handover: handover processes that are completely internal to one fixed radio termination.
Internal handover reconnects the call at the lower layers, while maintaining the call at the network layer.
NOTE: The lower layer reconnection can either be at the DLC layer (see connection handover)
or at the MAC layer (see bearer handover).
Interoperability: the capability of fixed parts and portable parts, that enable a portable part to obtain
access to teleservices in more than one location area and/or from more than one operator (more than one
service provider).
Interoperator roaming: roaming between fixed part coverage areas of different operators (different
service providers).
Intra-cell handover: the switching of a call in progress from one physical channel of one cell to another
physical channel of the same cell.
Intraoperator roaming: roaming between different fixed part coverage areas of the same operator (same
service provider).
Local NetWork (LNW): a telecommunication network capable of offering local telecommunication
services.
NOTE: The term does not include legal or regulatory aspects, nor does it indicate if the
network is a public network or a private network.
Locally unique (identity): the identity is unique within one FP or location area, depending on application.
Location area: the domain in which a portable part may receive (and/or make) calls as a result of a single
location registration.
Location registration: the process whereby the position of a DECT portable termination is determined to
the level of one location area, and this position is updated in one or more databases.
NOTE: These databases are not included within the DECT fixed radio termination.
Multiframe: a repeating sequence of 16 successive TDMA frames, that allows low rate or sporadic
information to be multiplexed (e.g. basic system information or paging).
Network (telecommunication network): all the means of providing telecommunication services between
a number of locations where the services are accessed via equipment attached to the network.
Operator (DECT operator): the individual or entity who or which is responsible for operation of one or
more DECT fixed parts.
NOTE: The term does not imply any legal or regulatory conditions, nor does it imply any
aspects of ownership.
Page 12
ETS 300 175-6: October 1992
Paging: the process of broadcasting a message from a DECT fixed part to one or more DECT portable
parts.
NOTE: Different types of paging message are possible. For example, the {Request paging}
message orders the recipient to respond with a call set-up attempt.
Paging area: the domain in which the portable part will be paged as a part of incoming call establishment.
NOTE: In general the paging area will be equal to the Temporary Portable User Indentity
(TPUI) domain since the TPUI is used for paging.
Portable HandSet (PHS): a single physical grouping that contains all of the portable elements that are
needed to provide a teleservice to the user.
NOTE: Portable handset is a subset of all possible portable parts. This subset includes all
physical groupings that combine one portable radio termination plus at least one
portable application in a single physical box.
Portable Part (DECT Portable Part) (PP): a physical grouping that contains all elements between the
user and the DECT air interface. Portable part is a generic term that may describe one or several physical
pieces.
NOTE: A DECT portable part is logically divided into one portable termination plus one or more
portable applications.
Portable radio Termination (PT): a logical group of functions that contains all of the DECT processes
and procedures on the portable side of the DECT air interface.
NOTE: A Portable radio Termination (PT) only includes elements that are defined in ETS
300 175. This includes radio transmission elements (layer 1) together with a selection
of layer 2 and layer 3 elements.
Private: an attribute indicating that the application of the so qualified term, e.g. a network, a equipment, a
service, is offered to, or is in the interest of, a determined set of users.
NOTE: The term does not include any legal or regulatory aspects, nor does it indicate any
aspects of ownership.
Public: an attribute indicating that the application of the so qualified term, e.g. a network, a equipment, a
service, is offered to, or is in the interest of, the general public.
NOTE: The term does not include any legal or regulatory aspects, nor does it indicate any
aspects of ownership.
Public Access Profile (PAP): a defined part of ETS 300 175 that ensures interoperability between fixed
parts and portable parts for public access services.
Public access service: a service that provides access to a public network for the general public.
NOTE: The term does not imply any legal or regulatory aspect, nor does it imply any aspects
of ownership.
Radio End Point (REP): a physical grouping that contains one radio transceiver (transmitter/receiver),
fixed or portable.
Radio Fixed Part (RFP): one physical sub-group of a fixed part that contains all the radio end points (one
or more) that are connected to a single system of antennas.
Registration: an ambiguous term, that should always be qualified. See either location registration or
subscription registration.
Page 13
ETS 300 175-6: October 1992
Roaming: the movement of a portable part from one fixed part coverage area to another fixed part
coverage area, where the capabilities of the fixed parts enable the portable part to make or receive calls in
both areas.
NOTE: Roaming requires the relevant fixed parts and portable part to be interoperable.
Roaming service: a service which can be used in more than one fixed part coverage area.
Service provider (telecommunications service provider): the individual or entity who or which
interfaces to the customer in providing telecommunications service.
NOTE 1: The term does not imply any legal or regulatory conditions, nor does it indicate whether
public service or private service is provided.
NOTE 2: The term service provider is also used with a different meaning in the ISO/OSI layered
model.
Single Radio Fixed Part (SRFP): a radio fixed part that contains only one radio end point.
NOTE: The SRFP is defined for DECT system analysis. Unless otherwise stated, a SRFP is
assumed to support multiple calls, and is limited only by the capacity of its single radio
end point.
Subscriber (customer): the natural person or the juristic person who has subscribed to
telecommunication services, and is therefore responsible for payment.
Subscription registration: the infrequent process whereby a subscriber obtains access rights to one or
more fixed parts.
NOTE: Subscription registration is usually required before a user can make or receive calls.
TDMA frame: a time-division multiplex of 10 ms duration, containing 24 successive full slots. A TDMA
frame starts with the first bit period of full slot 0 and ends with the last bit period of full slot 23.
TPUI domain: the domain over which every TPUI is (locally) unique.
NOTE: In general, the TPUI domain will be equal to the paging area and thereby equal to the
location area.
User (of a telecommunication network): a person or machine delegated by a subscriber (by a
customer) to use the services and/or facilities of a telecommunication network.

4 General description of FP and PP identities
Every radio fixed part broadcasts for its purpose a unique identity which contains a globally unique (to a
service provider) access rights identity. Every portable part has both a portable access rights key and an
international portable user identity. These operate as a pair. A portable part is allowed to access any radio
fixed part which broadcasts an access rights identity that can be identified by any of the portable access
rights keys of that portable part.
The international portable user identity is used to identify the portable in the domain defined by its related
access rights identity. The international portable user identity can either be locally unique or globally
unique.

Figure 1: General identity structure
The common base for the DECT identity structure is the Access Rights Class (ARC) and Access Rights
Details (ARD). These must be known by both the FP and the PPs. In the FP the ARC and ARD are called
Access Rights Identity (ARI), and in the PP they are called Portable Access Rights Key (PARK). The
distinction between PARK and ARI is that each PARK can have a group of ARDs allocated, PARK{y}. "y"
is the value of the PARK length indicator given in the PP subscription process.

Figure 2: Structure of PARK{y}
If the ARI is a primary ARI, i.e. PARI, it will form, together with a RFP number, the broadcast identity
RFPI. ARIs can also be less frequently broadcast as Secondary Access Rights Identities (SARIs) and may
also be available as Tertiary Access Rights Identities (TARIs), which are not broadcast, but are accessible
upon request.
The PUT and PUN form the PP user's identity, International Portable User Identity (IPUI). This identity can
either be globally unique or locally unique. IPUIs can be replaced by temporary and shorter identities,
TPUIs for paging.
A PP is identified by its pairs of PARK{y} and IPUI. A PP is only allowed to access a FP if one of its
PARKs includes one of the ARIs of the FP, i.e. the PARI, a SARI or a TARI.
4.1 Combinations of ARIs, PARKs and IPUIs
DECT provides a flexible radio access technology for a large variety of private and public networks or
systems. This leads to different requirements on e.g. sub-system grouping, distribution and installation of
equipment, identity allocations and subscription.
Therefore four access rights classes A - D and a number of international portable user identities have been
defined to meet the need for a differentiation in the identity structures.
The following table gives an overview of the combinations of the main identities. As described in subclause
6.2 some flexibility is allowed in combinations of the IPUI types, e.g. IPUI type N could be used by a
service provider in combination with any access rights class.

5 Fixed part identities
Fixed part identities are used to inform PPs about the identity of a DECT FP and the access rights to that
DECT FP and thereby reduce the number of access attempts from unauthorised portables. These
identities also carry information about domains for handover and location areas.
A DECT FP broadcasts this information on the NT-channel via all its radio fixed parts, at least once per
multiframe. A PP must be able to interpret necessary parts of this broadcast information to detect the
access rights to a system or even access rights agreements between system operators, i.e. operators A
and B have a bilateral agreement permitting their users to roam between their systems. These agreements
can change and cannot therefore be stored in PPs without updating them frequently. Therefore the FP
handles access rights information which is embedded in the identity structure.
The DECT identity structure provides solutions for residential, public and private environments. This can
also be extended to combinations between these environments, e.g. private groups of users within a public
DECT network, and e.g. public users access to private DECT networks.
The base for the identity structure is formed by the access rights classes and the access rights details.
ARC: shows the type of access to a DECT network, such as public private or residential.
ARD: this number is unique to the service provider. Its structure depends on the ARC.
The ARC and ARD together form the basic identity, the ARI:
ARI: this identity is globally unique to a service provider, and shows the access rights related to this
service provider. This identity may be applied to any number of FP installations. There are three categories
of ARIs;
PARI:primary ARI must be broadcast. This is also the most frequently broadcast ARI in order to give a
higher grade of service to users with these access rights. The PARI is broadcast over the NT-
channel. See NOTE below.
SARI:secondary ARI. SARIs are less frequently broadcast than PARIs. They are sent as a SARI-list on
the QT-channel. The message used for SARIs (there could be more than one SARI) is described in
subclause 5.5.
TARI: tertiary ARI. The TARI is not broadcast at all and is only available as a (or in a) "TARI accept"
message, which is an answer to a "TARI request" message including the relevant PARK{y}. See
subclause 5.5.6 and ETS 300 175-3 [3], subclause 7.3.6.4.
NOTE: Several FPs may apply the same ARI. However, as a PARI it has to be geographically
unique.

ETS 300 175-6: October 1992
The classification of primary, secondary and tertiary access rights gives the possibility for operators or
system owners to offer their subscribers/users an almost unlimited list of roaming agreements. This
classification can be seen as an iceberg with the PARI visible on the top followed by a less visible SARI
list and in the depth the invisible TARIs. The PP procedure for handling PARIs, SARIs and TARIs is
described in subclause 8.2.
Structure of ARI, see figure below:
ARC ARD
Figure 3: Structure of ARI
ARC: 8 available classes named A - H.
ARD: details, depends on the ARC.
One ARI together with a radio fixed part number, forms the RFPI. The ARI embedded in the RFPI is the
PARI.
The RFPI has three purposes:
- to carry the PARI;
- to uniquely identify RFPs geographically;
- to show domains for handover and location areas.
The RFPI is frequently transmitted as bits a8 to a47 in the A-field using the NT-channel and has therefore
a limitation of 40 bits. See ETS 300 175-3 [3], subclause 7.2.2.

E: this field indicates if there are any SARIs available. Value yes or no.
RPN: Radio fixed Part Number used for geographical separation.
Handover domains:
For DECT two handover domains are defined: internal handover (bearer and connection handover) to be
within a FP, and external handover to be between FPs. Internal handover is possible between RFPs that
have the same PARI in their RFPIs, i.e. only have changes in the RPN. See figure below.
RFPI E PARI RPN

Figure 5: Indication of internal handover domain
The connection handover domain is always identical to the internal handover domain. The cluster size
defines the bearer handover domain. A PP regards the cluster size as identical with the internal handover
domain, if not else has been indicated by the optional PT "Bearer handover information", see ETS 300
175-3 [3], subclause 7.2.4.3.8. The RFPI for access rights class
