Handling emergency signals in a cellular network

Abstract

An emergency signal is handled at a first network operated as a non-terrestrial cellular network. The first network operates on a same frequency as a second network, operated as a terrestrial cellular network. The first network is operated in a lower activity configuration, in which interference from the first network to the second network permits normal operation of the second network. In response to receiving the emergency signal from a user equipment at the first network, the first network is set to a higher activity configuration, causing increased interference from the first network to the second network than in the lower activity configuration. Related methods and devices are described.
