Abstract:
1. A method comprising: receiving, at a radio access network (RAN), a request to establish a call involving a wireless communication device (WCD) served by the RAN, wherein the WCD receives signals from the RAN via a plurality of wireless coverage areas at respective signal strengths, wherein the plurality of wireless coverage areas are defined by the RAN; determining a codec to use for the call and a target bitrate for the codec to use during the call; and based on the target bitrate, selecting a set of n wireless coverage areas through which the WCD and the RAN communicate during the call, wherein n is less than or equal to a predetermined maximum number, wherein the set of n wireless coverage areas are selected from the plurality of wireless coverage areas, wherein selecting the set of n wireless coverage areas through which the WCD and the RAN communicate during the call comprises selecting two or more wireless coverage areas, and wherein the WCD and the RAN communicating during the call involves the WCD and the RAN communicating substantially simultaneously via the two or more selected wireless coverage areas.
