ETSI ETSI EN 300 175-6 V2.4.1 (2012-04) 6 1 Scope The present document is one of the parts of the specification of the Digital Enhanced Cordless Telecommunications (DECT) Common Interface (CI). This part specifies the identities and addressing structure of the Digital Enhanced Cordless Telecommunications (DECT) Common Interface (CI). 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. The present document 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. SIST EN 300 175-6 V2.4.1:2012

Every PP has both a Portable Access Rights Key (PARK) and an International Portable User Identity (IPUI). These operate as a pair. A PP is allowed to access any radio FP which broadcasts an ARI that can be identified by any of the portable access rights keys of that PP. The IPUI is used to identify the portable in the domain defined by its related ARI. The IPUI can either be locally unique or globally unique. Figure 4.1 illustrates the identity structure.

ETSI ETSI EN 300 175-6 V2.4.1 (2012-04) 10 The common base for the DECT identity structure is the Access Rights Class (ARC) and Access Rights Details (ARD). These need to 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. ARCARDy bits"don't care" bits Figure 4.2: 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, IPUI. This identity can either be globally unique or locally unique. In addition to IPUIs, shorter temporary identities, TPUIs, may be used 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 five access rights classes A to E and a number of IPUIs have been defined to meet the need for a differentiation in the identity structures. Table 4.1 gives an overview of likely combinations of the main identities. As described in clause 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 ARC.

ETSI ETSI EN 300 175-6 V2.4.1 (2012-04) 11 5 FP identities FP 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 unauthorized portables. A DECT FP broadcasts this information on the NT-channel via all its Radio FPs (RFPs), at least once per multiframe. A PP needs to 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 ARCs and the ARDs: 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 or to the equipment (e.g. in the case of residential and business applications this number is assigned by the manufacturer). 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 has to be broadcast. This is also the most frequently broadcast ARI in order to give a higher grade of service to use
