Abstract
Disclosed herein is a method for selecting coverage areas as candidates for a handoff, and in particular, for a bidirectional handoff. An exemplary method may involve (a) engaging in a communication session via an access network, wherein an uplink connection is provided for uplink traffic in the communication session and a downlink connection is provided for downlink traffic in the communication session; (b) determining uplink-resource demand and downlink-resource demand of the communication session; (c) using the uplink-resource demand of the communication session as a basis for selecting one or more coverage areas in the access network as candidates for an uplink handoff of the uplink connection; and (d) using the downlink-resource demand of the communication session as a basis for selecting one or more coverage areas in the access network as candidates for a downlink handoff of the downlink connection.
