Title (EN) INTEGRATION OF 802.21 MEDIA INDEPENDENT HANDOVER FUNCTIONALITY TO RADIO INTERFACE LAYER AND TELEPHONY SERVER
(FR) INTÉGRATION D'UNE FONCTIONNALITÉ DE TRANSFERT INDÉPENDANT DU SUPPORT DANS UNE COUCHE D'INTERFACE RADIO ET UN SERVEUR TÉLÉPHONIQUE
Abstract: front page image
(EN)A radio interface layer media independent handover (RIL MIH) client (610) functionality enables transparent inter-system handover of a wireless transmit/receive unit (WTRU) between different radio access technologies (RATs), without user intervention. The RIL MIH client interacts with RIL drivers (630, 635) and proxies (605), informs the RIL proxies of the handover status, then the proxies interact with a new driver in use. A WTRU is modified to add MIH functionality to a telephony server to support inter-system handover.
(FR)Une fonctionnalité client de transfert indépendant du support de la couche d'interface radio (RIL MIH) permet un transfert inter-systèmes transparent d'une unité d'émission/réception sans fil (WTRU) entre différentes technologies d'accès radio (RAT), sans l'intervention de l'utilisateur. Le client RIL MIH interagit avec les pilotes et proxys RIL, informe les proxys RIL de l'état du transfert, puis les proxys interagissent avec un nouveau pilote utilisé. Une WTRU est modifiée pour ajouter une fonctionnalité MIH à un serveur téléphonique afin de prendre en charge le transfert inter-systèmes.
