Abstract:
1. A method comprising: acquiring, at a network equipment, one or more time samples associated with a time that a plurality of first devices stay in a coverage range of the network equipment; estimating an amount of time that a second device will stay in the coverage range based at least in part on the one or more acquired time samples, wherein the estimated amount of time changes over time as the one or more acquired time samples change over time, and wherein said estimating the amount of time further comprises processing the one or more acquired time samples using a stochastic process; estimating a context lifetime for the second device based at least in part on the estimated amount of time, wherein the context lifetime comprises an amount of time for which network resources to be used during a handoff of the second device are to be reserved; receiving a pre-authentication request from the second device; and determining whether to pre-authenticate the second device based at least in part on the estimated amount of time or on the estimated lifetime of network resources to be reserved for the second device.
