In addition, the user of the wireless device can manually initiate the handoff by actuating a handoff selector of the wireless device.

Abstract: A communication system provides for a handoff of a hybrid mobile station (MS) between a legacy network implementing a non-high rate packet data (non-HRPD) communication technology and a network implementing a high rate packet data (HRPD) communication technology. In one embodiment, the legacy network receives a handoff trigger and redirects the MS to the HRPD network.

In still other embodiments, the handoffs may be controlled by a Mobile Switching Center.
