Abstract

The present disclosure relates to a base station in a cellular communication network and methods of operation thereof. In one embodiment, a base station determines that the base station is transitioning to an unavailable state. The base station then notifies one or more radio network nodes with which the base station conducts base-station-to-node communication that the base station is unavailable. Thereafter, in one embodiment, the one or more radio network nodes cease communication attempts with the base station. In this manner, the radio network nodes can avoid spending additional resources on attempts to re-establish communication connections to base stations that tend to be offline more often (e.g., low-power base stations (LP-BSs)).
