System and Method for Time Saving Cell Search for Mobile Devices in Single and Multiple Radio Technology Communication Systems

A cellular device comprising a stacked protocol having an upper layer in communications with a lower layer, the cellular device comprising:

• a multiple carrier detection unit configured to receive a plurality of wireless carrier signals and providing a respective plurality of output digital streams, wherein the upper layer is configured to (i) generate a plurality of cell search parameter sets for a respective plurality of target searches and (ii) provide the plurality of cell search parameter sets to the lower layer, and wherein the lower layer is configured to control the multiple carrier detection unit to detect the wireless carrier signals according to the frequencies in the cell search parameter sets;
• and
• a digital processing system in communication with the multiple carrier detection unit, the digital processing system configured to process the digital streams according to the cell search parameter sets to generate signal processing results for each of the respective target searches,
• wherein the upper layer is configured to receive at least one of the signal processing results, and cause the cellular device to (i) camp on at least one cell corresponding to the at least one signal processing result and (ii) connect to the at least one cell.
