Abstract
When a cell phone fails in location registry to a base station, it removes the base station from a candidate group. Then it searches for and captures, for the next location registry, a base station whose pilot signal has the highest electric field intensity among the updated candidate group. When the registry is yet to be successful, the cell phone prohibits the location registry with maintaining an idle (waiting) state. Here, the pilot signals are observed among the candidate group. When a certain base station whose pilot signal exceeds a preset level of electric field intensity is detected, the idle handoff to the certain base station is executed. This success of the idle handoff then resumes the location registry to the certain base station.
