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 Recommendations ITU-T X.200 [i.3] and 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.

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 (COMS);
• 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.
