Optimal load-based wireless session context transfer


Abstract
A subscriber access unit for transferring session context in wireless communication is disclosed. The access unit contains first context establishing circuitry for establishing a first wireless session context associated with a first wireless coverage area; locating circuitry for determining whether the subscriber access unit is located concurrently in the first wireless coverage area and a second wireless coverage area; loading factor receiving circuitry for receiving a first loading factor and a second loading factor indicative of a throughput load associated with the first and second coverage areas respectively; comparison circuitry for comparing the first loading factor with the second loading factor; and second context establishing circuitry for selectively establishing a second wireless session context continuous with the first wireless session context, the second context associated with the second wireless coverage area, based on output of the circuitry comparing the first and second loading factors.
