A system determines if a primary paging channel should be received based on an examination of a quick paging channel. A first QPCH symbol is examined (102) and the normalized pilot energy is determined (104). If the normalized pilot energy is above a first threshold (106), the symbol is demodulated and the QPCH-symbol-to-pilot-energy ratio is determined (110) and compared against another threshold (114). If the normalized pilot energy is below the first threshold, the system proceeds to the second QPCH symbol immediately. Based on the two comparisons, a second QPCH signal is examined (108) or the system sleeps (116). If the second signal is examined, and if its normalized pilot energy is high enough, it also is demodulated and the ratio of the sum-of-the-combined-QPCH-symbols to the sum-of-the-combined-pilot-energies is determined (122). If this ratio exceeds a threshold (124), the primary paging channel is processed (120); otherwise the system sleeps (116).
