8  Conclusions and recommendationsWord‑p. 53

This Technical Report analyses a number of use cases related to the use of 5G in a residential setting. It is argued that providing an excellent 5G experience in an in-home setting is very important as in-home is where many 5G users will spend a large amount of time, especially when using highly demanding services such as UHD-TV, AR/VR or mobile gaming. Based on the different use cases, requirements have been generated on topics such as Premises Radio Access System, evolved Residential Gateway, service discovery, provisioning, et cetera.
There are also some requirements related to 5G-LAN, where the existing 5G-LAN requirements already in [2] are being expanded.
The resulting potential requirements have been consolidated in clause 7 of the TR. The content of clause 7 should be considered as the basis of normative Release 18 requirements to support 5G for residential use cases.

The Resident networks overview contains the following entities.
  • evolved Residential Gateway (eRG).
  • Premises Radio Access System (PRAS).
  • Customer Premises Network (CPN)
  • User Equipment (UE).
  • Non-3GPP Device.

A.3  Customer Premises Network entitiesWord‑p. 54

A.3.1  evolved Residential Gateway (eRG)Word‑p. 54

The evolved Residential Gateway is defined in clause 3.1.
The eRG is connected to the 5GC via e.g. fixed, mobile, or hybrid access following specifications for Wireline-Wireless Convergence [7].
Connectivity between the eRG and the UE, non-3GPP Device, or PRAS can use any suitable non-3GPP technology (e.g. Ethernet, optical, WiFi).
Up

A.3.2  Premises Radio Access System (PRAS)Word‑p. 54

The Premises Radio Access System is defined in clause 3.1.
A PRAS can use licensed spectrum, but also can use unlicensed spectrum.
Connectivity between the PRAS and the UE can use NR radio access (Uu) or non-3GPP radio access.
The PRAS only provides non-3GPP radio access to UEs with 3GPP credentials that are checked by the 5GC (similar to other non-3GPP access to the 5GC). The PRAS is not e.g. a WiFi AP that provides non-3GPP access to devices with non-3GPP credentials that are checked by the WiFi AP itself.
The PRAS is part of the Customer Premises Network and therefore connected to the eRG.
The PRAS may also provide E-UTRA radio access.

A.3.3  Customer Premises Network (CPN)Word‑p. 55

The Customer Premises Network is defined in clause 3.1.

A.3.4  User Equipment (UE)Word‑p. 55

The User Equipment is defined in [1].

A.3.5  Non-3GPP deviceWord‑p. 55

The Non-3GPP device is defined in clause 3.1.
