1. A method comprising:
- obtaining periodically a plurality of parameter values for a plurality of parameters of one or more network layers on a mobile client device, associated with accessing a plurality of heterogeneous wireless networks;
determining whether to request update(s) for one or more of the heterogeneous wireless networks, based at least in part on the obtained parameter values; and
requesting an update for each of the heterogeneous wireless networks determined to have an update requested.

11. An apparatus comprising:
-
a fuzzy logic controller; and
a media independent handover function block coupled to the fuzzy logic controller, the media independent handover function block being adapted to obtain periodically a plurality of parameter values of a plurality of network layer parameters of the apparatus, associated with accessing a plurality of heterogeneous wireless networks, and to input the obtained parameter values to the fuzzy logic controller to generate a determination on whether to request for update(s) for the plurality of heterogeneous wireless networks. - View Dependent Claims (12, 13, 14, 15, 16)

17. An article of manufacture comprising:
-
a storage medium; and
a plurality of programming instructions designed to enable a controller to fuzzify obtained updates comprising parameter values of a plurality of heterogeneous wireless networks into a plurality of fuzzy sets, and to apply a plurality of user policies to the fuzzy sets to select a first of the heterogeneous wireless networks for a mobile client device hosting the article of manufacture to access, replacing a second of the heterogeneous wireless networks accessed by the mobile client device. - View Dependent Claims (18, 19, 20, 21)
