Abstract

Methods and apparatus for accomplishing inter-frequency, inter-network, and inter-tier soft handoff are disclosed which use dual transmission/reception or compression techniques. The invention includes a transceiver disposed between a user interface and an antenna interface. The transceiver links the antenna and the user interface by monitoring signals at a mobile station received via the antenna from a plurality of wireless communication network types, determining a best candidate for soft handoff based upon the monitored signals, the best candidate being associated with one of the plurality of wireless communication network types and performing a handoff to the best candidate. One embodiment of the invention includes a first receiver operating at a first frequency, a second receiver operating a second frequency, a first transmitter operating at the first frequency and a second transmitter operating at the second frequency, wherein the first receiver receives signals from a first type of wireless communication network type at the first frequency and the second receiver receives signals from a second type of wireless communication network type at the second frequency. The transceiver monitors the first half of a normal frame sequence period for a first transmission frame being transmitted at the first frequency and a second half of a normal frame sequence period for a second transmission frame being transmitted at the second frequency. The first transmission frame may be power control bits, pilot strength signals or voice signals.
