Title (EN) MULTI-RADIO HANDOVER MANAGER SYSTEM AND ALGORITHMS FOR HETEROGENEOUS WIRELESS NETWORKING
(FR) SYSTÈME GESTIONNAIRE DE TRANSFERT MULTI-RADIO ET ALGORITHMES POUR RÉSEAUTAGE SANS FIL HÉTÉROGÈNE
Abstract:
(EN) 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.
(FR) L'invention concerne un gestionnaire de transfert multi-radio et des algorithmes permettant son fonctionnement. Le gestionnaire de transfert multi-radio (MRHM) réduit au minimum le temps « d'activité » d'une radio quand l'autre radio est connectée à Internet. Le MRHM empêche également des transferts de WLAN à WWAN inter-technologies d'accès radio (RAT) non nécessaires dans un WLAN « multi-AP », dans lequel une itinérance de WLAN à WLAN intra-RAT (couche 2) est possible. Le MRHM réduit au minimum l'influence de changements d'adresse IP dus à un transfert de WWAN à WLAN sur une session TCP/IP active. Et le MRHM optimise son algorithme de déclenchement de transfert sur la base du trafic et de l'environnement.
