Abstract
Methods are disclosed for initiating a handoff of a wireless access terminal based on a set of one or more factors including the determined value of the Reverse Activity Bit (RAB). The set of one or more factors may also further include (i) a determined round-trip delay for a bi-directional communications link between the first wireless access node and the wireless access terminal, wherein the bi-directional communications link comprises a forward link from the first wireless access node to the wireless access terminal and a reverse link from the wireless access terminal to the first wireless access node, and/or (ii) a determined forward-link signal-strength indicator for a forward link from the first wireless access node to the wireless access terminal.
