6.8 Dynamic policy control
The 5G system shall support the creation and enforcement of prioritisation policy for users and traffic, during
connection setup and when connected.
NOTE: Prioritisation, pre-emption, and precedence of critical traffic associated with certain priority services (e.g.,
MPS and Emergency) are subject to regional/national regulatory and operator policies.
The 5G system shall support optimised signalling for prioritised users and traffic where such signalling is prioritized
over other signalling traffic.
Based on operator policy, the 5G system shall allow flexible means to create and enforce priority among the different
service flows by authorized users.
Based on operator policy, the 5G system shall allow real-time, dynamic, secure and limited interaction with the QoS
and policy framework for modification of the QoS and policy framework by authorized users.
Based on operator policy, the 5G system shall maintain a session when prioritization of that session changes in real time,
provided that the new priority is above the threshold for maintaining the session.
Based on operator policy, the 5G system shall allow modifications by authorized users and context aware network
functionality to the QoS and policy framework to have a variable duration.
6.9 Connectivity models
6.9.1 Description
The UE can connect to the network directly (direct network connection), connect using another UE as a relay UE
(indirect network connection), or connect using both types of connections. These UEs can be anything from simple
wearables, such as sensors embedded in clothing, to a more sophisticated wearable UE monitoring biometrics. They can
also be non-wearable UEs that communicate in a Personal Area Network such as a set of home appliances (e.g., smart
thermostat and entry key), or the electronic UEs in an office setting (e.g., smart printers), or a smart flower pot that can
be remotely activated to water the plant. The relay UE can access the network using 3GPP or non-3GPP access (e.g.,
WLAN access, fixed broadband access). 3GPP and non-3GPP radio technologies and fixed broadband technologies can
be supported for connectivity models between the remote UE and the relay UE. 3GPP RAT over licensed band or
unlicensed band can be supported for connectivity models.
When a remote UE is attempting to establish an indirect network connection, there might be several relay UEs that are
available in proximity of the remote UE and support discovery and remote UE-to-relay UE connection establishment. A
remote UE may support selection of an appropriate relay UE among the available relay UEs.
6.9.2 Requirements
The following set of requirements complement the requirements listed in 3GPP TS 22.278 [5], clause 7B.
The connection between a remote UE and a relay UE shall be able to use 3GPP RAT or non-3GPP RAT and use
licensed or unlicensed band.
The connection between a remote UE and a relay UE shall be able to use fixed broadband technology.
The 5G system shall support indirect network connection mode in a VPLMN when a remote UE and a relay UE
subscribe to different PLMNs and both PLMNs have a roaming agreement with the VPLMN.
The 5G system shall be able to support a UE using simultaneous indirect and direct network connection mode.
The 5G system shall be able to support QoS for a user traffic session between the remote UE and the network using
3GPP access technology.
For a 5G system with satellite access, the following requirements apply:
- A 5G system with satellite access shall be able to support relay UE’s with satellite access.
