System and method providing low power operation in a multimode communication device
First Claim
1. A system for providing low-power operation in a multimode communication device, the system comprising:
- at least one radio module that is adapted to communicate in a plurality of communication modes and operate in at least a first power-save mode; and
at least one module that is adapted to;
determine whether a first communication network corresponding to a first communication mode of the plurality of communication modes might be available by analyzing at least one non-informational signal characteristic; and
determine, based at least in part on the determined availability of the first communication network, whether to operate the at least one radio module in a respective mode other than the first power-save mode.

Abstract
A system and method providing low-power operation in a multimode communication device. Various aspects of the present invention may, for example, include at least one radio module that is adapted to communicate in a plurality of communication modes. The at least one radio module may also be adapted to operate in at least a first power-save mode. At least one module may, for example, be adapted to analyze at least one non-informational aspect of a signal (e.g., a received radio signal) to determine whether a first communication network corresponding to a first communication mode of the plurality of communication modes might be available. The at least one module may then, for example, be adapted to determine, based at least in part on the determined availability of the first communication network, whether to operate the at least one radio module in a respective mode other than the first power-save mode.

15. In a multimode communication device adapted to communicate in a plurality of communication modes, a method for providing low-power operation, the method comprising:
-
analyzing at least one non-informational signal characteristic to determine whether a first communication network corresponding to a first communication mode of the plurality of communication modes might be available; and

29. A system for providing low-power operation in a multimode communication device, the system comprising:
-
at least one radio module that is adapted to communicate in a plurality of communication modes and operate in at least a first power-save mode, wherein the at least one radio module comprises;
a first receiver module adapted to consume a first amount of power while processing a communication signal corresponding to a first communication mode; and
a second receiver module adapted to consume a second amount of power while processing a communication signal corresponding to the first communication mode, where the second amount of power is less than the first amount of power; and
at least one module that is adapted to;
determine whether a first communication network corresponding to the first communication mode of the plurality of communication modes might be available by analyzing at least one informational signal characteristic of a signal received by the second receiver module; and
determine, based at least in part on the determined availability of the first communication network, whether to operate the at least one radio module in a respective mode other than the first power-save mode. - View Dependent Claims (30, 31, 32, 33, 34)
