Method, apparatus and system architecture for performing handovers between heterogeneous wireless networks
First Claim
1. A method comprising:
- receiving, at a mobile subscriber station (MSS), wireless service from a first wireless network;
detecting the MSS is within range of at least one base station for a second wireless network;
for each of the at least one base station, obtaining parameters quantifying the wireless service available via that base station; and
employing the parameters in a handover decision algorithm to determine if a handover of service from the first wireless network to the second wireless network is to be performed.

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.
