Abstract
A wireless communication device (WCD) can communicate with either a first radio access network (RAN) that uses a packet-switched network under the control of a call server for voice calls, or a second RAN that uses a circuit-switched network for voice calls. When served by the first RAN, the WCD determines whether it should be served by a relay base station of the first RAN (a base station that has a wireless backhaul to a donor base station), a non-relay base station of the first RAN, or a base station of the second RAN, by measuring a communication latency with the call server. If the latency is greater than a threshold latency for voice calls, the WCD initiates a handover to a non-relay base station (if served by a relay base station) or to a base station of the second RAN (if served by a non-relay base station).
