Embodiments of the present invention are directed to controlling CDMA registration on a multi-technology handset. By controlling CDMA registration on a multi-technology handset, efficient handoffs between different technologies can occur. In one embodiment, the multi-technology handset operates using CDMA and at least one second technology. The second technology can be wireless fidelity (WiFi) or worldwide interoperability for microwave access (WiMAX), for example. The multi-technology handset includes at least a dual mode controller (DMC), a CDMA controller, a second technology controller, as well as radios for the CDMA and the second technology.
