Abstract
In an effort to have a mobile station choose a lowest level cell to lock onto, a method and apparatus for standby state cell selection in a layered cellular telephone system is proposed. Upon entering a standby state, the mobile station is provided with parameters containing a value for a minimum threshold downlink signal strength level and information pertaining to hierarchical levels associated with a plurality of cells within the cellular telephone system. The mobile station measures downlink signal strengths of a plurality of radio frequencies transmitted by the plurality of cells and selects a cell having a lowest level in the hierarchy of cells which transmits a radio frequency having a greatest downlink signal strength, the downlink signal further having a signal strength above the minimum threshold level.
