ABSTRACT:
A mobile station in an idle state is associated with a current sector-carrier that has a current pilot channel at a current carrier frequency. In response to a request to originate a call, the mobile station compares its current sector-carrier with one or more candidate sector-carriers that have pilot channels at carrier frequencies distinct from the current carrier frequency. The mobile station measures received signal strengths of the current carrier frequency and the one or more candidate carrier frequencies and measures pilot signal levels of the current pilot channel and the one or more candidate pilot channels. If a candidate sector-carrier has a carrier frequency with a received signal strength that exceeds that of the current sector-carrier, and has a pilot channel with a pilot signal level that exceeds that of the current sector-carrier, the mobile station uses that candidate sector-carrier to transmit a call origination message.
