摘要：Techniques to efficiently attempt acquisition of a packet data system (e.g., an IS-
856 system). If a terminal has acquired one or more channels in a voice/data system (e.g.,an IS-2000 system), then it can attempt acquisition on channels in the packet data systemthat are co-located with the acquired channels in the voice/data system. Multipleacquisition modes may be used, and on-going acquisition attempts on the co-locatedchannels may be performed using one acquisition mode at a time in order to reducepower consumption. Acquisition attempts may be performed in a “ping-pong” mannerto improve the likelihood of acquisition. For a ping-pong search, an acquisition attempt ismade on the most recently acquired channel prior to an acquisition attempt on each ofthe remaining channels. Received signal strength estimates may also be obtained forselected channels and may be used to determine whether or not to attempt acquisitionon these channels.
