Abstract
Method, apparatus, and system architecture for performing handovers between heterogeneous wireless networks. While receiving wireless service from a base station for a first wireless network, a mobile subscriber station (MSS) device roams within range of one or more access points (APs) corresponding to a second wireless network. The MSS obtains parameters for each AP quantifying the wireless service available via that AP. The parameters are employed as inputs to a handover decision algorithm to determine if a handover of service from the first wireless network to an AP for the second wireless network is to be performed. In one embodiment, the handover decision algorithm is effected via a fuzzy logic controller that is implemented via execution of software on the MSS.
