Patent ID: 8600459

Claim:
A system for providing low-power operation in a multimode communication device, the system comprising: at least one radio module operable to communicate in a plurality of communication modes and operable in at least a first power-save mode in which power is saved without determining information from signals corresponding to a first communication mode of the plurality of communication modes; and at least one module operable to, while the at least one radio module is operating in the first power-save mode: determine whether a first communication network corresponding to the first communication mode might be available by analyzing at least one signal characteristic; and if it is determined that the first communication network corresponding to the first communication mode might be available, then transition operation of the at least one radio module from the first power-save mode to an operating mode in which information is determined from signals corresponding to the first communication mode, and wherein the information is decoded utilizing a portion of decoding capability that is less than a full decoding capability of the at least one module associated with the first communication mode.
