SIST ETS 300 691 E1:2003 is the Slovenian adoption of ETS 300 691 Edition 1, a European Telecommunications Standard from ETSI for Private Integrated Services Network (PISN) Cordless Terminal Mobility (CTM) location handling services. It specifies the stage 1 service description for CTM roaming within a single PISN, covering Cordless Terminal Location Registration (SS-CTLR) and Transfer of Service Profile (ANF-CTSP). It is intended to guide later stage 2 and stage 3 specifications.

What does SIST ETS 300 691 E1:2003 specify?

SIST ETS 300 691 E1:2003 specifies the user-level service description for CTM location handling in a PISN. The standard focuses on how a cordless terminal user registers and deregisters at a location area, and how service profile information is transferred or accessed so services can follow the user.

The document is organized into scope, normative references, definitions and abbreviations, then two main service descriptions:

• SS-CTLR - Cordless Terminal Location Registration
• ANF-CTSP - Transfer of Service Profile

The foreword identifies it as a European Telecommunications Standard produced by ETSI, and the document includes overall SDL diagrams for both service parts. The scope also makes clear that the standard applies to CTM only within a single PISN.

What are the key requirements of SIST ETS 300 691 E1:2003?

SIST ETS 300 691 E1:2003 describes how CTM location handling is provided, invoked, rejected, and related to other services. The practical point is that it tells implementers when the network updates location data, when it blocks a request, and when it may trigger related profile handling.

SS-CTLR service behavior

SS-CTLR makes the CTM user's location known to the PISN. In practice, this allows incoming calls to be routed to the current location area and lets the user keep using PISN services from that area.

The service is provided by arrangement with the PISN authority, is activated on provision, and is deactivated on withdrawal. Interrogation is not applicable. The document also says the network may use a permanent identifier or, for security, temporary identifiers, and it may use authentication before completing registration.

Registration and deregistration

SS-CTLR is invoked when the location area changes or after a period of deregistration. Registration updates the current location and deletes the earlier location information. Deregistration tells the PISN that the user is temporarily unavailable for service use, including incoming calls.

If registration is rejected, the reason can include an unknown user identity, lack of permission in the current location area, failed authentication, or temporary unavailability. Deregistration is rejected if the user was not registered in that location area. This matters because the network must return a clear cause so the terminal or user can retry correctly.

Service interactions

SS-CTLR has defined interactions with identification services, call diversion, call transfer, path replacement, call completion, do not disturb, call offer, call intrusion, and incoming and outgoing CTM call handling. Of note, registration may cancel call completion, and an incoming or outgoing call may be rejected if it happens while SS-CTLR procedures are in progress or during deregistration.

SS-CTLR may also invoke ANF-CTSP. In practice, that means a location change can lead the network to update or access the user’s service profile so service behavior stays consistent across locations.

ANF-CTSP behavior

ANF-CTSP maintains a CTM user's service profile independent of location area. The network may transfer service profile details or access them remotely, and updates can be reflected in the original or copied profile.

ANF-CTSP is permanently activated and does not support interrogation. It may be invoked when requested service details are not available at the current location area, after later profile changes, and through interactions with call diversion, do not disturb, incoming CTM call handling, outgoing CTM call handling, and SS-CTLR. For implementers, this means profile data has to remain consistent across location changes and related service events.

What terms does SIST ETS 300 691 E1:2003 define?

SIST ETS 300 691 E1:2003 defines the main terms used to describe CTM location handling.

• Cordless Terminal Mobility (CTM) - The ability of a cordless terminal to keep using PISN services while moving, with the network tracking its location.
• Private Integrated Services Network (PISN) - The private integrated services network environment in which these services operate.
• Cordless Terminal Location Registration (SS-CTLR) - The supplementary service that registers or deregisters the CTM user at a location area.
• Transfer of Service Profile (ANF-CTSP) - The additional network feature that transfers or accesses service profile information across location areas.
• Location area - The coverage area in which a cordless terminal can make and receive calls after a single location registration.
• Service profile - The set of PISN services and options available to a PISN user.
• PISN authority - The body or representative that arranges the service with the service provider.

Who uses SIST ETS 300 691 E1:2003?

SIST ETS 300 691 E1:2003 is used by people specifying, designing, implementing, or assessing CTM services in private networks. That includes network architects, equipment vendors, service providers, and testers working on PISN mobility features.

It is also useful for PISN authorities and technical buyers who need to understand what location registration and service profile handling are supposed to do before choosing or validating an implementation. Because it is a stage 1 document, it helps align service intent before lower-level signaling and protocol work begins.

Which standards are used with SIST ETS 300 691 E1:2003?

SIST ETS 300 691 E1:2003 relies on several dated and undated references that supply terminology, method, and modeling rules.

• ETS 300 171 - Gives the functional models and information flows for circuit mode basic services used as the service base.
• ETS 300 415 - Provides PTN terms and definitions, including referenced terms such as ANF and authentication.
• ISO/IEC 11579-1 - Defines reference configurations for PISN exchanges (PINX).
• ETS 300 387 - Describes the three-stage method used to specify basic and supplementary services.
• CCITT Recommendation I.130 - Describes how telecommunication services are characterized from the user point of view.
• ITU-T Recommendation I.210 - Gives principles for ISDN-supported telecommunication services and how to describe them.
• ITU-T Recommendation Z.100 - Defines SDL, the notation used for the overall behavior diagrams.

What does the SIST ETS 300 691 E1:2003 document contain?

SIST ETS 300 691 E1:2003 contains service descriptions, procedure descriptions, service interaction notes, and overall SDL diagrams for SS-CTLR and ANF-CTSP. The SDL diagrams show the main service state behavior and the request-response flow between the PISN and the served user or current location area.

The document also includes the foreword, transposition dates, scope, normative references, and a definitions and abbreviations section. In practice, this structure supports service specification, implementation planning, and conformance interpretation for CTM location handling in a PISN.

1 Scope
This European Telecommunication Standard (ETS) describes the stage one of the location handling
services for Private Integrated Services Networks (PISNs). It comprises two related but distinct service
descriptions. The first is a service allowing a Cordless Terminal Mobility (CTM) user to register or
deregister at a location area in the PISN (SS-CTLR). The second is an Additional Network Feature (ANF)
used by different parts of the PISN to transfer or access service profiles (ANF-CTSP). Stage one is an
overall service description from the user's point of view, but does not deal with the details of the human
interface itself, see CCITT Recommendation I.130 [5].
The Cordless Terminal Location Registration Supplementary Service (SS-CTLR) enables a CTM user to
register at, or deregister from, the current location area within the PISN. The ability to register at different
location areas in the PISN at different times enables the CTM user to maintain the provided services
(including the ability to make and receive calls) at different access points. Deregistration is used to inform
the PISN that the CTM user is temporarily unable to make use of the provided services (including the
receipt of incoming calls).
The Transfer of Service Profiles Additional Network Feature (ANF-CTSP) enables different parts of the
PISN to transfer or access service profiles, thereby allowing CTM users to maintain their service profiles
when changing location area within the PISN.
This ETS contains the stage 1 specification of the location handling services. Service specifications are
produced in three stages according to the method described in ETS 300 387 [4].
The purpose of the stage 1 specification is to guide and constrain the work at stage 2 and stage 3. Where
the text indicates the status of a requirement (i.e. as strict command or prohibition or as authorisation
leaving freedom as a capability or possibility) this is reflected in the text of the relevant stage 2 and stage 3
standards.
This ETS applies to CTM only within a single PISN.
Conformance to this ETS is met by conforming to the stage three standards with the field of application
appropriate to the equipment being implemented. Therefore, no method of testing is provided for this ETS.
