The present invention includes a method and an apparatus for reducing power consumption in a wireless telephone. The wireless telephone is programmed to enter a reduced power mode for a sleep interval of time upon failing to access a base station. Additionally, the overall base station accessing process is considerably shortened by only searching once through the sequence of available carrier spectrums (e.g., digital and analog carriers for multi-mode mobile stations) before entering the reduced power mode. Also, when searching through a code division multiple access (CDMA) channel, the present invention includes searching only once through all pseudo-random number (PN) code timing locations when searching for a base station. |
