1. A method comprising:

  • a radio access network (RAN) determining that roaming data indicates that a wireless communication device (WCD) is likely to begin roaming to a non-preferred wireless coverage area, wherein the RAN defines a first preferred wireless coverage area, and wherein the RAN currently serves the WCD via the first preferred wireless coverage area; and

    based on at least the roaming data indicating that the WCD is likely to begin roaming, the RAN (i) selecting a second preferred wireless coverage area, wherein the second preferred wireless coverage is also defined by the RAN, and (ii) communicating with the WCD substantially simultaneously via the first and second preferred wireless coverage areas, wherein communicating substantially simultaneously via the first and second preferred wireless coverage areas comprises during establishment of a call in which the WCD participates, the RAN transmitting a respective channel assignment message to the WCD via each of the first and second preferred wireless coverage areas.
