Abstract:
1. A method comprising: determining for a network node that a service-impacting event has occurred or is imminent to establish a reduced power condition; reducing transmit power, by the network node, to a lower level when the reduced power condition has been established; determining for the network node that an event subsequent to the service-impacting event has occurred and that the reduced power condition no longer applies; restoring the transmit power by the network node when the reduced power condition no longer applies, wherein the determining for the network node that a service-impacting event has occurred or is imminent to establish a reduced power condition comprises at least one of: detecting a link outage between the network node and a mobility management entity, detecting a link outage between the network node and a neighboring network node, and receiving an indication that a planned outage is imminent.
