Methods and apparatus for base-station-assisted handover between WiMAX (Worldwide Interoperability for Mi-crowave Access) and CDMA (Code Division Multiple Access) EVDO (Evolution- Data Optimized) or 1xRTT (one times Radio Transmission Technology, or 1x) networks during normal operation of a dual- mode mobile station (MS) are provided. By having a base station (BS) using one radio access technology (RAT) broadcast information about a BS in a neighboring cell employing a different RAT, the methods and apparatus may improve service continuity during handover.
L'invention concerne des procédés et un appareil pour un transfert intercellulaire assisté par une station de base entre des réseaux WiMAX ("Worldwide Interoperability for Microwave Access") et CDMA (Accès multiple par répartition en code) EVDO ("Evolution-Data Optimized") ou 1xRTT ("one times Radio Transmission Technology", ou 1x) pendant le fonctionnement normal d'une station mobile (MS) bimode. Les procédés et appareil de l'invention permettent d'améliorer la continuité de service pendant le transfert intercellulaire au moyen d'une station de base (BS) utilisant des informations de diffusion de technologie d'accès radio (RAT) associées à une BS dans une cellule voisine employant une RAT différente.
