6G-NTN
Adaptation to PPDR or Temporary Events
An unplanned event such as a natural disaster occurs and triggers the rapid intervention of first responders. It is assumed that in the wake of this event, the TN infrastructure was temporarily damaged. Two types of users are considered on the scene: i) victims with consumer handheld UE and ii) first responders with a plurality of UE encompassing consumer and professional handheld UE, vehicular mounted, drone-mounted, and pole mounted. Although the NTN segment can immediately serve these users, some prioritisation in resource allocation needs to be defined and enforced for the benefit of the first responders. Since the TN is progressively restored, both TN and NTN need to coexist in these changing conditions. Likewise, all considered UEs need to be able to seamlessly switch from TN to NTN and vice-versa.
The first user, identified within this use case, uses a consumer to always be able to connect, even in the event of unexpected events, via NTN/TN. In addition, the second user is an operator to fill a lack of coverage caused by unexpected events. Hence, NTN shall be able to integrate momentary additional mounted stations for closing coverage holes.
