6.16 Markets requiring minimal service levels

22.2613GPPRelease 18Service requirements for the 5G systemTS

6.16.1 Description

A key aspect of 5G system flexibility is the ability to support both the very high-end markets as well as very low end markets. Some systems will be deployed in areas where there are constraints on energy resources (e.g. sporadic access to power) and lower end user expectations for availability, reliability, and data rates. In such cases, the system needs additional flexibility to adapt power consumption needs based on fluctuations in power availability. The system should be efficient in order to provide essential services in harsh environments (e.g. far remote rural areas, very large territories) while taking into account the local constraints (adapting resources consumptions to long distances, dealing with variable conditions and possibly disconnections). Content delivery should be optimized in order to reduce constraints on transport networks, on low-end UEs (e.g. small screen, limited energy consumption), variable network conditions, and client profiles.

6.16.2 Requirements

In constrained circumstances (e.g. reduced power supply), the 5G system shall be able to support a minimal user experience (e.g. user experienced data rate of [100] kbit/s, E2E latency of 50 ms, lower availability of the network of 95%).

The 5G system shall support centralized automation and management of the network in order to reduce local management tasks.

The 5G system shall support a mechanism to reduce data transfer rate at the cell edge for very large coverage area (e.g. 100 kbit/s for more than 100 km cell coverage, 1 Mbit/s for 100 km cell coverage).

The 5G system shall be able to give priority to services (e.g. e-Health) when resources are limited.
