Abstract

An improved device and method for determining when to start a timer that applies a temporary offset to a signal quality measurement of a cell that is a candidate for reselection in a 3GPP Hierarchical Cell Structured wireless communications system. For a cell ranking criterion R, the timer is started to apply the temporary offset according to present invention rules that insure that the temporary offset is not applied until a candidate is eligible for reselection, preventing premature expiration of the timer and unintended cell reselection. A present invention mobile unit that uses the improved method includes a housing, a central processor, a timer for applying the temporary offset, and a memory. The memory includes computer code that applies the claimed invention rules for starting the timer.
