Digital Enhanced Cordless Telecommunications (DECT) - Common Interface (CI) - Part 5: Network (NWK) layer
The present document is one of the parts of the specification of the Digital Enhanced Cordless Telecommunications (DECT) Common Interface (CI).
The present document specifies the Network (NWK) layer. The NWK layer is part 5 of the ETSI EN 300 175 and layer 3 of the DECT protocol stack. The present document only specifies the C-plane (control plane) of the DECT NWK layer. It contains no specification for the U-plane (user plane) because the U-plane is null for all services at the DECT NWK layer. The C-plane contains all of the internal signalling information, and the NWK layer protocols are grouped into the following families of procedures:
• Call Control (CC);
• Supplementary Services (SS);
• Connection Oriented Message Service (COMS);
• ConnectionLess Message Service (CLMS);
• Mobility Management (MM);
• Link Control Entity (LCE).
The present document uses the layered model principles and terminology as described in Recommendation ITU-T X.200 [i.3] and Recommendation ITU-T X.210 [i.4]. The present document includes New Generation DECT, a further development of the DECT standard introducing wideband speech, improved data services, new slot types and other technical enhancements. The present document also includes super-wideband and fullband speech and audio services.
Digitalne izboljšane brezvrvične telekomunikacije (DECT) - Skupni vmesnik (CI) - 5. del: Omrežna plast (NWK)
Ta dokument je eden od delov specifikacije skupnega vmesnika (CI) za digitalne izboljšane brezvrvične telekomunikacije (DECT).
Ta dokument določa omrežno plast (NWK). Omrežna plast je 5. del standarda ETSI EN 300 175 in plast 3 sklada protokolov digitalnih izboljšanih brezvrvičnih telekomunikacij. Ta dokument določa samo C-raven (nadzorno raven) omrežne plasti digitalnih izboljšanih brezvrvičnih telekomunikacij. Ne vsebuje specifikacije za U-raven (uporabniško raven), ker je U-raven na omrežni plasti digitalnih izboljšanih brezvrvičnih telekomunikacij enaka nič za vse storitve. C-raven vsebuje vse notranje signalizacijske informacije in protokoli omrežne plasti so združeni v naslednje družine postopkov:
• nadzor klicev (CC),
• nadomestne storitve (SS),
• sporočilna storitev, usmerjena na povezavo (COMS),
• sporočilna storitev brez povezave (CLMS),
• upravljanje mobilnosti (MM),
• entiteta kontrole povezave (LCE).
Ta dokument uporablja načela in terminologijo modela plasti, kot je opisano v priporočilih ITU-T X.200 [i.3] in X.210 [i.4]. Ta dokument vključuje novo generacijo digitalnih izboljšanih brezvrvičnih telekomunikacij, nadaljnji razvoj standarda za digitalne izboljšane brezvrvične telekomunikacije, ki uvaja širokopasovni govor, izpopolnjene podatkovne storitve, nove tipe rež in druge tehnične izpopolnitve. Ta dokument vključuje tudi super širokopasovne in polnopasovne govorne in zvočne storitve.

ETSI EN 300 175-5 V2.7.9 (2019-08) - Digital Enhanced Cordless Telecommunications (DECT); Common Interface (CI); Part 5: Network (NWK) layer
ETSI EN 300 175-5 V2.8.1 (2019-12) - Digital Enhanced Cordless Telecommunications (DECT); Common Interface (CI); Part 5: Network (NWK) layer
Overview
SIST EN 300 175-5 V2.8.1:2020 defines the Network (NWK) layer of the Digital Enhanced Cordless Telecommunications (DECT) Common Interface (CI). Published by the Slovenian Institute for Standardization (SIST), this standard aligns with ETSI EN 300 175-5 V2.8.1 (2019-12) and specifies Layer 3 protocols within the DECT stack, focusing exclusively on the C-plane (control plane). The NWK layer is foundational for managing signaling, call control, supplementary services, mobility, and messaging in DECT-based wireless systems.
This standard is critical for manufacturers, system integrators, and telecom operators who require interoperable, high-quality, and feature-rich cordless communication solutions. It supports the ongoing evolution of DECT technology, including New Generation DECT, with enhanced speech and data services.
Key keywords: DECT standard, network layer, common interface, mobility management, cordless telecommunication, signaling protocols, ETSI EN 300 175.
Key Topics
- Control Plane Focus: The standard specifies only the C-plane protocols of the NWK layer-responsible for internal signaling and management activities within DECT systems.
- Procedure Families:
- Call Control (CC): Establishment, management, and termination of voice and data calls.
- Supplementary Services (SS): Protocols for additional features such as call hold, transfer, and conferencing.
- Connection Oriented Message Service (COMS): For reliable, connection-based message transfer.
- ConnectionLess Message Service (CLMS): For quick, one-way communications requiring no connection setup.
- Mobility Management (MM): Processes and messages that enable roaming, user authentication, location updating, and access rights management.
- Link Control Entity (LCE): Establishment and management of logical links within the DECT system.
- Layered Model Compliance: Utilizes ITU-T X.200 and X.210 terminology and principles for OSI layering, ensuring compatibility and clear protocol separation.
- Enhanced Services: Addresses new and future requirements with provisions for wideband, super-wideband, and fullband audio services as part of New Generation DECT.
- Signaling Structures: Comprehensive definition of message formats, information elements, and protocol discrimination for robust interoperability between DECT devices.
Applications
The practical applications of SIST EN 300 175-5 V2.8.1:2020 cover a wide range of professional and consumer telecommunications scenarios:
