During a call, a radio access network (RAN) may substantially simultaneous communicate with a wireless communication device (WCD) via multiple wireless coverage areas. The number of wireless coverage areas used for this substantially simultaneous communication may vary based on the call type. Thus, for instance, if the call type is a real-time call type, the RAN may use more wireless coverage areas when communicating with the WCD to improve the quality of the call. But, if the call type is a non-real-time call type, the RAN may use fewer wireless coverage areas when communicating with the WCD so that wireless resources are conserved.

The method of claim 1, wherein communicating substantially simultaneously via each wireless coverage area in the selected set comprises: during establishment of a call in which the WCD participates, the RAN transmitting a respective channel assignment message to the WCD via each wireless coverage area in the selected set. 3. A method comprising: a radio access network (RAN) determining that a first extent of wireless coverage areas is available for facilitating substantially simultaneous communication with a wireless communication device (WCD);the RAN receiving, from the WCD, a request to establish a call of a non-real-time call type, wherein the RAN determines the non-real-time call type based on a service option that is associated with the request to establish the call; andbased on the non-real-time call type, the RAN communicating with the WCD via a second extent of wireless coverage areas, wherein the second extent of wireless coverage areas is a subset of the first extent of wireless coverage areas, wherein (i) when the second extent of wireless coverage areas consists of one wireless coverage area, the RAN communicates with the WCD via the one wireless coverage area, and (ii) when the second extent of wireless coverage areas consists of more than one wireless coverage area, the RAN communicates with the WCD substantially simultaneously via each wireless coverage area in the second extent, wherein communicating substantially simultaneously with the WCD via each wireless coverage area in the second extent comprises during establishment of a call in which the WCD participates, the RAN assigning, to the WCD, a respective traffic channel from each wireless coverage area in the second extent, and during an initial portion of the call, the RAN exchanging bearer traffic with the WCD via each of the assigned traffic channels. 4. The method of claim 3, wherein the non-real-time call type is a non-interactive non-real-time call type. 5. The method of claim 3, wherein communicating substantially simultaneously via each wireless coverage area in the second extent comprises: the RAN exchanging communications with the WCD, wherein the communications traverse each wireless coverage area in the second extent at approximately the same time. 6. The method of claim 3, wherein communicating substantially simultaneously with the WCD via each wireless coverage area in the second extent comprises: during establishment of a call in which the WCD participates, the RAN transmitting a respective channel assignment message to the WCD via each wireless coverage area in the second extent. 7. The method of claim 3, wherein the RAN transmits and receives identical copies of the same bearer traffic via each of the assigned traffic channels. 8. An article of manufacture including a non-transitory computer-readable medium, having stored thereon program instructions that, when executed by a radio access network (RAN), cause the RAN to perform operations comprising: determining that a first extent of wireless coverage areas is available for facilitating substantially simultaneous communication with a wireless communication device (WCD);receiving, from the WCD, a request to establish a call of a non-real-time call type, wherein the RAN determines the non-real-time call type based on a service option that is associated with the request to establish the call; andbased on the non-real-time call type, communicating with the WCD via a second extent of wireless coverage areas, wherein the second extent of wireless coverage areas is a subset of the first extent of wireless coverage areas, wherein (i) when the second extent of wireless coverage areas consists of one wireless coverage area, the RAN communicates with the WCD via the one wireless coverage area, and (ii) when the second extent of wireless coverage areas consists of more than one wireless coverage area, the RAN communicates with the WCD substantially simultaneously via each wireless coverage area in the second extent, wherein communicating substantially simultaneously with the WCD via each wireless coverage area in the second extent comprises during establishment of a call in which the WCD participates, the RAN assigning, to the WCD, a respective traffic channel from each wireless coverage area in the second extent, and during an initial portion of the call, the RAN exchanging bearer traffic with the WCD via each of the assigned traffic channels. 9.
