5.5 Use case on the 3GPP network as an information source to the UTM p. 14

5.5.1 Description p. 14

The UTM is a complex system in which actors outside the 3GPP System work to ensure the required safety level of UAS operations. For this reason, the UTM is defined by GUTMA (Global UTM Association) as "a system of stakeholders and technical systems collaborating in certain interactions, and according to certain regulations, to maintain safe separation of uncrewed aircraft, between themselves and from ATM users, at very low level, and to provide an efficient and orderly flow of traffic"

A system like UTM requires a high-quality set of data flows to remain fully aware of the system it is operating within and to effectively meet the mission brief. In figures 1 and 2 below, the GUTMA architecture [2] shows that a high number of data sources are considered to keep the UTM functional.

The 3GPP System can act as a data source towards the UTM in order to provide spatial, surveillance, meteorological, and real-time positioning information.

5.5.2 Pre-conditions p. 15

A UTM exists which is capable of accepting a 3GPP network as data source. A partner 3GPP operator is prepared to supply information to the UTM based on the capabilities of the network. Agreements on trust, responsibility, liability, privacy, and data management have been made.

5.5.3 Service Flows p. 15

A UTM determines what data is required from the 3GPP network which can act as an information source.
Based on the capabilities of the 3GPP network, an operator begins to gather data according to agreements made with a UTM operator where the UTM provides the type of information and optional conditions regarding such information (e.g. reporting for a specific area, reporting specific events, etc.). This data is gathered from a number of sources which may include the following: RAN awareness of UE altitude (detect UEs above a certain altitude from the ground), Wireless Sensing results, UE registration, UE location reporting, network-based UE location determination.
The operator begins to feed data towards a UTM according to the information requested by the UTM.
The UTM accepts the data from the operator and is responsible for processing (corelating data sets, identifying objects, deduplication) and acting on (warnings, notifications) this data according to mechanisms outside the scope of 3GPP.

5.5.4 Post-conditions p. 15

The UTM has an increased situational awareness because of the increased data provided by the 3GPP network.

[P.R 5.5.6-001] Based on operator policy and UTM's request, the 5G system shall be able to provide UTM with a UEs' location (specifically 5GC Location Services derived positioning or UE-derived positioning e.g. from GNSS) and identity.

[P.R 5.5.6-002] Subject to user consent and national or regional regulation, based on operator policy, and the UTM's request, the 5G system may be able to provide aerial object location(s) derived by 5G Wireless Sensing to the UTM.
