Patent ID: 7054290

Claim:
A method of wireless communication employing a terminal, the terminal configured to tune either to a High Data Rate (HDR) carrier in an HDR network or to a 1× Radio Transmission Technology (1×RTT) carrier in a 1×RTT network, the method comprising: tuning the terminal to the HDR carrier; establishing a packet data communication over the HDR carrier using the terminal; periodically tuning the terminal to the 1×RTT carrier for a limited time in order to check for incoming 1×RTT communications sending a 1×RTT packet hand-over request from the terminal to transfer the packet data communication from the HDR carrier to the 1×RTT carrier; handing the packet data communication over to the 1×RTT carrier from the HDR carrier; and establishing a 1×RTT communication over the 1×RTT carrier when an incoming 1×RTT communication is detected while also maintaining the packet data communication over the 1×RTT carrier; and tuning the terminal back to the HDR carrier when the 1×RTT communication is terminated.
