Selection of wireless coverage areas and operating points of media codecs

摘要

A request to establish a call involving a wireless communication device (WCD) served by a radio access network (RAN) may be received. The WCD may receive signals from the RAN via a plurality of wireless coverage areas at respective signal strengths. The plurality of wireless coverage areas may be defined by the RAN. A media codec to use for the call and a target bitrate for the media codec to use during the call may be determined. Based on the target bitrate, a set of n wireless coverage areas through which the WCD and the RAN communicate during the call may be selected. The value of n may be between one and a predetermined maximum number. The set of n wireless coverage areas may be selected from the plurality of wireless coverage areas.

主权项

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 via a primary wireless coverage area at a primary signal strength, wherein the WCD receives signals via the one or more secondary wireless coverage areas at respective secondary signal strengths; determining respective differences between the primary signal strength and the respective secondary signal strengths; determining a target codec bitrate to use during the call; and based on the target codec bitrate, selecting a set of n wireless coverage areas through which the WCD and the RAN communicate during the call, wherein the selected set includes the primary wireless coverage area and zero or more of the secondary wireless coverage areas for which the respective differences between the primary signal strength and the respective secondary signal strengths are less than a threshold difference.
