Patent ID: 7107080

Claim:
A method to determine when a wireless terminal has been paged by a servicing base station, the method comprises: receiving an encoded paging burst on a paging channel; decoding the encoded paging burst to produce a decoded paging burst; determining that the decoded paging burst contains a null page for the wireless terminal; processing the encoded paging burst to produce a null page pattern, wherein the null page pattern comprises a bit pattern; entering a sleep mode for a sleep mode period; awakening from the sleep mode to receive an additional encoded paging burst on the paging channel; processing the additional encoded paging burst to produce a processed encoded paging burst, wherein the processed encoded paging burst comprises a plurality of soft decision bits; comparing the processed encoded paging burst to the null page pattern comprises comparing each bit of the null page pattern to a corresponding soft decision bit of the processed encoded page burst to produce a plurality of comparisons; and when the number of comparisons exceeds a comparison threshold, determining that the additional encoded paging burst is a null page.
