Claim:
1. A method for managing wireless communication service comprising: providing, by a first radio access network (RAN), a plurality of coverage areas in which to serve user equipment devices (UEs) according to a first air interface protocol, wherein the first RAN is interconnected with a fallback RAN that is configured to serve UEs according to a second air interface protocol, and wherein the first RAN is configured to support an inter-RAN fallback process in which the first RAN passes pre-registration signaling and call-setup signaling between the fallback RAN and UEs served by the first RAN to facilitate transition of UEs from being served over the first air interface protocol by the first RAN to being served with calls over the second air interface protocol by the fallback RAN; detecting, by the first RAN, a threshold extent of failure of the inter-RAN fallback process with respect to one or more UEs that are each served by the first RAN in a first coverage area of the plurality of coverage areas provided by the first RAN; and responsive to detecting the threshold extent of failure, the first RAN processing handover of at least one UE from the first coverage area provided by the first RAN to at least one second coverage area of the plurality of coverage areas provided by the first RAN.
