Question: In the context of Event A5H1, what is the primary condition for the User Equipment (UE) to consider leaving this event, based on the specified inequalities?
Option 1: At least one of the conditions Mp - Hys1 > Thresh1, Mn + Ofn + Ocn + Hys1 < Thresh2, or Ms + Hys2 < Thresh3 is fulfilled.
Option 2: All conditions Mp - Hys1 > Thresh1, Mn + Ofn + Ocn + Hys1 < Thresh2, and Ms + Hys2 < Thresh3 must be simultaneously fulfilled.
Option 3: The UE's Aerial altitude (Ms) is the sole determining factor for leaving the event, based on the inequality Ms + Hys2 < Thresh3.
Option 4: The neighbour cell's measurement (Mn) without offsets or hysteresis must exceed Thresh2 to leave the event.
Explanation: According to the specifications for Event A5H1, the leaving condition is satisfied when at least one of the three specified inequalities is fulfilled. This means the UE considers leaving the event if any of these conditions (Mp - Hys1 > Thresh1, Mn + Ofn + Ocn + Hys1 < Thresh2, or Ms + Hys2 < Thresh3) are met.
