A RAN may be configured to receive a first call setup request relating to a first WCD, and a second call setup request relating to a second WCD. The first WCD may communicate using a first air-interface or a second air-interface, and the second WCD my communicate using the second air-interface and not the first air-interface. The RAN may determine that the first WCD and the second WCD are contending for a resource of a wireless coverage area defined using the second air-interface. Based on the first WCD and the second WCD contending for the resource, the first WCD communicating using the first air-interface or the second air-interface, and the second WCD communicating using the second air-interface and not the first air-interface, the RAN may assign the resource to the second WCD.
