Methods and apparatus for base-station-assisted handover between WiMAX (Worldwide Interoperability for Microwave 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.
