摘要

A method is provided whereby a mobile cellular terminal can acquire and lock onto a low duty-cycle reference beacon transmitted from a private radio system base station. The terminal alternately scans the private radio beacon frequency spectrum (over a large frequency range) and processes the received signals off-line until the reference beacon is found. During each scan, only a limited amount of sampling time is allowed, in order to keep the amount of sampled data manageable. The processing time is selected so as to be long enough for the terminal to complete any required (software) analysis of the sampled data. Consequently, even if the terminal misses a reference beacon that arrives during the processing period, the next consecutive reference beacon will be found.
