6G-NTN

In the context of rescue scenarios, reliable communication, including voice and video communication, is an important means for Search and Rescue (SAR) teams. The overall coordination, especially of all maritime rescue teams, requires voice and video communication via satellite or additional HAPs; hence, NTN is key for the success and improvement of such activities, also relying on enhanced positioning methods and additional sensor data collection.
The scenario mainly takes place while being NTN-connected; due to the mobility of satellites, NTN/NTN mobility needs to be considered.
In this use case, two types of users are identified: i) the users connect to the coast guard service by means of a consumer handheld UE, and ii) potentially, a professional terminal to connect to the coast guard.
Both terminal types shall be switchable between NTN/TN.
