Abstract: A method and system for managing connectivity when a signaling controller is going to be taken out of service. The method involves determining that a WCD served by the signaling controller provides wireless backhaul connectivity for a relay base station, and responsively taking action to proactively transition that WCD from being served by the signaling controller to being served by a different signaling controller without the WCD detaching and reattaching. This may enable the WCD to maintain its network connectivity, including its assigned network address, and may thus enable the relay base station to maintain its network connectivity as well, thereby helping to maintain connectivity for WCDs served by the relay base station and continuity of interfaces between the relay base station and other core network entities.
