6.11 Context-aware network

22.2613GPPRelease 18Service requirements for the 5G systemTS

6.11.1 Description

A variety of sensors such as accelerometer, gyroscope, magnetometer, barometer, proximity sensor, and GPS can be integrated in a UE. Also, different applications running on the UE can have different communication needs (e.g. different traffic time). In addition, a UE can support different access technologies such as NR, E-UTRA, WLAN access technology, and fixed broadband access technology. The information gathered by sensors, the utilized access technologies, the application context, and the application traffic characteristics can provide useful information to the applications installed in the UE and can also help the 5G system utilize resources in an efficient and optimized way.

6.11.2 Requirements

The 5G system shall support network resource utilization efficiently and network optimization based on system information, including:- network conditions, such as network load and congestion information;

– information on served UEs such as access information (e.g. 3GPP access, non-3GPP access), cell type (e.g. macro cell, small cell), user experienced data rate;

– application’s characteristics (e.g. expected traffic over time);

– information on prioritized communication such as user subscription profile and priority level, priority services (e.g. MPS, Emergency, and Public Safety), application used for priority communications (e.g. voice, video, and data) and traffic associated with priority communications (signalling and media);

– subject to user consent, enhanced traffic characteristic of UE (e.g. Mobility information (e.g. no mobility, nomadic, spatially restricted mobility, full mobility), location, sensor-level information (e.g. direction, speed, power status, display status, other sensor information installed in the UE), application-level information (e.g. foreground applications, running background application, and user settings).

The 5G system shall support mechanisms to collect system information for network optimization within an operator configured time scale.
