SIST EN 300 370 V1.3.1:2003 is the Slovenian adoption of ETSI EN 300 370 Version 1.3.1. It specifies how DECT and GSM interwork for 3,1 kHz speech service, so DECT fixed parts and portable parts can carry basic GSM voice telephony over the DECT air interface. The document is updated with approved change requests and is written for equipment that connects DECT access to a GSM PLMN.

What does SIST EN 300 370 V1.3.1:2003 specify?

SIST EN 300 370 V1.3.1:2003 specifies the DECT access protocols and Fixed Part (FP) and Portable Part (PP) mappings needed for GSM basic voice telephony over DECT. It is organized into scope, references, definitions, interworking requirements, interworking mappings, connection type definitions, and four annexes.

The scope focuses on GSM Phase 2 interworking at the MSC attachment, and it leaves supplementary services, data services, short message services, fax, and non-GSM networks outside the profile. The document also sets expectations for a PP that can distinguish this GSM-attached FP from a GAP-only FP.

Annex	What it covers
Annex A	Derivation of the DECT ciphering key CK from GSM Kc
Annex B	Deletion of GSM Kc, CKSN, TMSI and LAI
Annex C	Mapping of equipment identities
Annex D	Physical attachment models for the FP

What are the key requirements of SIST EN 300 370 V1.3.1:2003?

SIST EN 300 370 V1.3.1:2003 defines mandatory interworking requirements for both the FP and the PP. In practice, this means implementers must support the profile’s call control, mobility, security and mapping rules, not just radio connectivity.

Access rights and profile context

Clause 5 says the PP shall remain backwards compatible with the minimum requirements of GAP, while the FP shall at least support the profile’s required procedures. The broadcast attribute a39, “SIM services available”, is the key indicator that the FP is attached to GSM, and class D use is central to this profile. For a buyer or integrator, this tells you whether a terminal is meant for GSM-backed DECT access or for a GAP-only environment.

Call handling

Clause 6.1.1 covers normal outgoing calls, emergency calls, incoming calls, and normal or abnormal release. The FP maps DECT call setup information either from CC-INFO or from CC-SETUP depending on how dialling digits are presented, and it starts the GSM Connection Management (CM) service procedure before sending the GSM Setup. In practice, this is what makes basic voice calling work across the DECT-GSM boundary.

Registration, identity, and security

Clause 6.1.2 covers authentication, identity, location registration, detach, temporary identity assignment, ciphering, and the CM service procedure. Annex A defines how the DECT ciphering key CK is derived from GSM Kc, and Annex B covers deleting GSM identifiers after authentication-related events. For implementers, this is the security and mobility core of the profile.

Handover and paging

Clause 6.1.2.9 and clause 6.3.2.7 describe external handover between FPs and the associated PP behavior. The profile uses handover candidate handling, handover request and confirmation, ciphering on the new link, and release of the old connection. Clause 6.1.3 and 6.3.3 cover paging-related interworking, which is needed so a GSM-terminated call can reach the correct DECT PP.

Mappings and coding

Clause 6.1.6 and 6.1.7 define message mappings and information element mappings between GSM and DECT in both directions. Clause 6.1.8 then defines the fields inside those information elements. This is the part engineers use when they need message-by-message interoperability, not just a functional description.

Connection types

Clause 7 defines the main DECT connection types used by the profile. This helps implementers choose the right combination of U-Plane and C-Plane behavior for the supported services.

What terms does SIST EN 300 370 V1.3.1:2003 define?

• Attach - The process by which a PP tells an FP that it is operative within that FP’s coverage and access rights.
• Authentication - The process used to verify that a DECT subscriber is a legitimate user of a particular FP.
• Fixed Part (FP) - The DECT-side physical grouping between the local network and the DECT air interface.
• Portable Part (PP) - The user-side physical grouping between the user and the DECT air interface.
• Interworking Unit (IWU) - The function that connects sub-networks by mapping procedures, messages and information elements.
• Location registration - The process that updates the PP’s position to the level of one location area.
• Handover - The switching of an ongoing call from one physical channel to another.

Who uses SIST EN 300 370 V1.3.1:2003?

SIST EN 300 370 V1.3.1:2003 is used by DECT and GSM equipment manufacturers, especially teams building FPs, PPs, IWUs and GSM attachment functions. It is also used by network operators, service providers, and integrators who need DECT access to a GSM core network.

Test and approval engineers use it to check call setup, registration, ciphering, paging, and handover behavior against the defined mappings. Quality managers and buyers use it to confirm whether a product is meant for basic GSM voice over DECT rather than broader GSM services.

Which standards are used with SIST EN 300 370 V1.3.1:2003?

The profile builds on EN 300 175 parts 1 to 8, which provide the DECT Common Interface layers, identities, security features and speech coding. It also relies on EN 300 444 for GAP minimum requirements and EN 300 466 for the wider DECT/GSM service framework.

On the GSM side, the key companions are ETS 300 557 for GSM radio interface layer 3, ETS 300 590 for the MSC-BSS interface, and ETS 300 499 for MSC-FP interconnection. For test and implementation context, it also references ISO/IEC 9646-6, TBR 6, TBR 10, and the companion interworking profile parts EN 300 703, ETS 300 756, ETS 300 764, and ETS 300 792.

What does the SIST EN 300 370 V1.3.1:2003 document contain?

The document contains detailed procedure descriptions, message mappings, information element mappings, and field-level coding rules for DECT-GSM interworking. Clause 6 is the largest part and includes call handling, authentication, identity, location registration, detach, temporary identity assignment, ciphering, paging, and external handover.

It also includes timing and error-handling behavior, plus figures showing the main call and handover sequences. Annexes A to D provide the cryptographic derivation, identity deletion, identity mapping, and physical attachment models needed for implementation and verification.
