Abstract:
1. A method comprising: receiving, by a radio access network (RAN), a call establishment request seeking to establish a call involving a wireless communication device (WCD), wherein the RAN serves WCDs of a first type and WCDs of a second type, wherein WCDs of the first type are configured to communicate with the RAN using a first air-interface or a second air-interface, and wherein WCDs of the second type are configured to communicate with the RAN using the second air-interface and not the first air-interface; determining whether the WCD is of the first type or the second type; if the WCD is of the first type, selecting wireless coverage areas, for supporting the call, from a first candidate set of wireless coverage areas; if the WCD is of the second type, selecting wireless coverage areas, for supporting the call, from a second candidate set of wireless coverage areas, wherein the first candidate set of wireless coverage areas is a subset of the second candidate set of wireless coverage areas; and in response to the call establishment request, assigning, to the WCD, traffic channels from each wireless coverage area selected for supporting the call, wherein the wireless coverage areas selected for supporting the call are defined by the RAN and operate in accordance with the second air-interface.
