A radio access network (RAN) may receive a request to establish a call involving a wireless communication device (WCD) served by the RAN. The WCD may receive signals from the RAN, via a plurality of wireless coverage areas, at respective signal strengths. A set of n wireless coverage areas may be selected from the plurality of wireless coverage areas to support communications related to the call, where n is at least 2. A service option to use for the call may be determined, where the service option indicates a call type. Based on the indicated call type, at least one wireless coverage area may be removed from the set of n wireless coverage areas. The call may be established between the RAN and the WCD.
