SIST ETS 300 816 E1:2003 is the SIST version of ETS 300 816 Edition 1, an ETSI European Telecommunications Standard for the Handover Additional Network Feature (ANF-CTH) in a Private Integrated Services Network (PISN). It gives the stage 1 service description for Cordless Terminal Mobility (CTM) handover, defining how a CTM user can keep an established call while moving between overlapping location areas at the same PINX.

What does SIST ETS 300 816 E1:2003 specify?

SIST ETS 300 816 E1:2003 specifies the stage 1 description of ANF-CTH for a PISN. Stage 1 describes the service from the user's point of view and sets the behavior that later stages must support.

The document says handover may occur only between Fixed Radio Parts (FRPs) at the same PINX. It is organized into scope, normative references, definitions and abbreviations, and Clause 4, which covers the service description, procedures, interactions, and interworking considerations.

What are the key requirements of SIST ETS 300 816 E1:2003?

• ANF-CTH supports ongoing call continuity - Clause 4.1 says a CTM user can continue a call while moving between overlapping location areas in the same visitor area. In practice, the network has to set up the new radio connection before releasing the old one.

• The feature applies to all basic services, with a practical limit - Clause 4.1.2 links ANF-CTH to all basic services defined in ETS 300 171, but notes that it should be used only where a brief interruption is acceptable. For implementers, this means the service is not meant for every call type or every user expectation.

• ANF-CTH is permanently active - Clause 4.2.2.1 states that activation is permanent, while registration and interrogation are not applicable. This means the feature is not managed as a user-selectable subscription service.

• Invocation happens only after call establishment - Clause 4.2.2.2 says handover is invoked only once a call is established, and it may be rejected during call setup. That matters because the network must wait until the call is stable before attempting transfer.

• Security during handover is preserved where possible - Clause 4.2.2.2 says that if speech is encrypted before handover, it should remain encrypted after handover, and the handover may be rejected if that is not possible. An implementation option allows security parameters from the old connection to be reused on the new one.

• Failure falls back to the old connection - Clause 4.2.3.2 requires the call to continue on the old connection if the new connection cannot be established, with any reserved resources released. This is the fail-safe behavior that protects the call from unnecessary drop.

• Most supplementary services and ANFs do not interact - Clause 4.3 lists many services with “No interaction,” including number and name identification, call diversion, call transfer, path replacement, call completion, Do not disturb, Call Offer, Call Intrusion, ANF-CTMI, ANF-CTMO, and ANF-CTSP. For users, this means ANF-CTH is designed to coexist cleanly with a broad set of related features.

• Authentication and location handling can affect handover - Clause 4.3.12 allows ANF-CTH to invoke SS-CTAT and SS-CTAN, and a failed identity check can cause rejection. Clause 4.3.13 says SS-CTLR may be needed to resolve a temporary identity or non-PISN number before handover completes.

What terms does SIST ETS 300 816 E1:2003 define?

• Additional Network Feature (ANF) - A network feature defined in ETS 300 415 that adds service behavior within the PISN.
• Cordless Terminal Mobility (CTM) - The cordless terminal mobility concept used for user movement and call continuity in the PISN.
• PISN - Private Integrated Services Network, the network environment for this standard.
• PINX - Private Integrated Network eXchange, the local network exchange used in the handover context.
• CTM user - A PISN user whose calls are processed by ANF-CTH.
• Established call - A PISN call where communication between the end users is possible.
• Location area - The coverage area in which a cordless terminal may make and receive calls after a single location registration.
• Visitor area - For this ETS, the visitor area is confined to the coverage area of a single PINX.

Who uses SIST ETS 300 816 E1:2003?

This standard is used by PISN and telecommunication engineers who design CTM handover behavior in cordless systems. It is also relevant to switch and PINX vendors, system integrators, and service planners who need to implement call continuity between overlapping location areas.

Quality managers and test teams use it to check whether a stage 3 implementation matches the stage 1 service intent. Buyers and technical evaluators can use it to confirm that a product supports CTM handover in the way their network design requires.

Which standards are used with SIST ETS 300 816 E1:2003?

• ENV 41005 - Provides the method for specifying basic and supplementary services of private telecommunication networks, including the three-stage approach used here.
• ETS 300 171 - Provides the functional model and information flows for circuit-mode basic services and defines the basic-call basis used in this ETS.
• ETS 300 415 - Provides PISN terms and definitions, including ANF, authentication, cordless terminal, CTM, and visitor area.
• CCITT Recommendation I.210 - Provides the general principles for telecommunication services supported by an ISDN and how to describe them.

What does the SIST ETS 300 816 E1:2003 document contain?

SIST ETS 300 816 E1:2003 contains a service description, not a test method. Clause 4 explains how ANF-CTH works, when it may be invoked, what happens when the new connection succeeds or fails, and how security is handled during changeover.

It also groups related services and ANFs to show interaction behavior, with most entries stated as having no interaction. The document finishes with a history section that records its publication path.

Page 7ETS 300 816: February 19981ScopeThis European Telecommunications Standard (ETS) describes the stage 1 of the Cordless TerminalHandover Additional Network Feature (ANF-CTH) for a Private Integrated Services Network (PISN). Stageone is an overall service description from the user's point of view, but does not deal with the details of thehuman interface itself.ANF-CTH is an additional network feature that enables a Cordless Terminal Mobility (CTM) user tomaintain a call while moving between overlapping location areas belonging to the same visitor area.Service specifications are produced in three stages according to the method described in ENV 41005 [1].This ETS contains the stage 1 specification of the handover additional network feature.The purpose of the stage 1 specification is to guide and constrain the work at stage 2 and stage 3. Wherethe text indicates the status of a requirement (i.e. as strict command or prohibition or as authorizationleaving freedom as a capability or possibility) this shall be reflected in the text of the relevant stage 2 andstage 3 standards.Conformance to this ETS is met by conforming to the stage 3 standards with the field of applicationappropriate to the equipment being implemented. Therefore no method of testing is provided for this ETS.2Normative referencesThis ETS
