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 other embodiments, the legacy network (or HRPD network) receives a handoff trigger, obtains an allocation of HRPD network (or non-HRPD network) resources from the HRPD network (or non-HRPD network), and informs the MS of the allocated HRPD network (or non-HRPD network) resources. Subsequent to the establishment by the HRPD network (or non-HRPD network) of a traffic channel with the MS, the non-HRPD network (or HRPD network) releases non-HRPD network (or HRPD network) RF resources associated with the MS. In still other embodiments, the handoffs may be controlled by a Mobile Switching Center.

12. A method for a handoff of a hybrid mobile station from a network comprising a Mobile Switching Center (MSC) and implementing a non-high rate packet data (non-HRPD) communication technology to a network implementing a high rate packet data (HRPD) communication technology, the method comprising:
-
conveying forward link bearer traffic to, and receiving reverse link bearer traffic from, the mobile station via radio frequency (F) resources associated with the non-HRPD network;
receiving, by the non-HRPD network, a handoff trigger;
in response to receiving the handoff trigger, conveying a message to the MSC requesting a handoff of the mobile station;
in response to receiving the request, obtaining, by the MSC, an allocation of RF resources by tie HRPD network;
informing the mobile station, by the non-HRPD network, of the RF resources allocated by the HRPD network;
establishing, by the HRPD network, a traffic channel with the mobile station based on the RF resources allocated by the HRPD network; and
subsequent to the establishment by the HRPD network of a traffic channel with the mobile station, releasing, by the non-HRPD network, the RF resources of the non-HRPD network. - View Dependent Claims (13, 14, 15, 16, 17)
