Abstract:
1. In a radio access network (RAN) device of a wireless communication system, a method comprising: determining a rate of inbound handoffs of active communication sessions to a given wireless coverage zone from each of one or more neighboring wireless coverage zones, wherein the active communication sessions are carried for respective time intervals on one or more air interface between respective access terminals and at least the given wireless coverage zone; determining a respective rate of outbound handoffs of active communication sessions from the given wireless coverage zone to each of the one or more neighboring wireless coverage zones; based on the determined rate of inbound handoffs and on the determined respective rates of outbound handoffs, determining a weighted average of transmission rates supported by an air interface of the given wireless coverage zone and respective air interfaces of the one or more neighboring wireless coverage zones; upon receiving a request from an access terminal to set up a new communication session via the air interface of the given wireless coverage zone, determining a coding rate for the new communication session based on the determined weighted average of transmission rates; and transmitting an instruction to the access terminal to use the determined coding rate for air-interface communications for a duration of the new communication session.
