METHOD AND APPARATUS FOR SEARCHING FOR RADIO FREQUENCY SIGNALS BY A SUBSCRIBER UNIT IN A WIRELESS COMMUNICATION SYSTEM

摘要

A method and subscriber unit (SU) are provided that control an order in which a subscriber unit (SU) tunes to, and inspects, a frequency for a signal. When the SU activates in a wireless communication system, the SU searches for an RF signal by reference to a search list, wherein the search list maintains a prioritized list of channel numbers in association with a Public Land Mobile Network, an access technology, and a band number. In response to detecting the RF signal, the SU determines whether the RF signal is acceptable and, in response to determining that the RF signal is acceptable, connects to an access network associated with the RF signal.
