ABSTRACT:
A method, system, computer readable medium and subscriber access unit for transferring session context in wireless communication are disclosed. The method includes defining a first wireless coverage area provided to a subscriber access unit, establishing a first wireless session context for the subscriber access unit including a wireless connection associated with the first wireless coverage area, defining a second wireless coverage area provided to the subscriber access unit determining at the subscriber unit whether the subscriber access unit is located concurrently in the first wireless coverage area and the second wireless coverage area, determining a first loading factor and a second loading factor indicative of a throughput load associated with the first and second coverage areas respectively; comparing the first loading factor with the second loading factor, and selectively establishing a second wireless session context for the subscriber access unit which includes a wireless connection associated with the second wireless coverage area based on comparing the first and second loading factors.
