Abstract
A multi-radio handover manager and supporting algorithms are disclosed. The multi-radio handover manager (MRHM) minimizes the “on” time of one radio when the other radio is connected to the Internet. The MRHM also prevents unnecessary inter-RAT (radio access technologies) WLAN-to-WWAN handovers in a “multi-AP” WLAN, where intra-RAT WLAN-to-WLAN (layer 2) roaming is possible. The MRHM minimizes the impact of IP address changes due to WWAN-to-WLAN handover on an active TCP/IP session. And, the MRHM optimizes its handover-triggering algorithm based on traffic and environment.
