Claim of US Patent No. 10,117,223

1. A method of controlling paging of a wireless client device (WCD) in a wireless communication system having a plurality of base stations, wherein each base station is either (i) a relay base station having a wireless backhaul connection served by a donor base station or (ii) a non-relay base station not having a wireless backhaul connection served by a donor base station, the method comprising:encountering a trigger to page the WCD; and
responsive to the trigger, (a) identifying a most recent serving base station of the WCD, (b) making a determination of whether the identified base station is a relay base station or rather a non-relay base station, and (c) based on the determination, controlling whether to broadcast an initial page for the WCD via just the identified base station,
wherein (i) if the determination is that the identified base station is a non-relay base station, then the initial page for the WCD is broadcast via just the identified base station and (ii) if the determination is that the identified base station is a relay base station, then the initial page for the WCD is broadcast via both the identified base station and the donor base station that serves the wireless backhaul connection for the identified base station.
