Patent ID: 8055256

Claim:
A method for selecting scanning rates in a multi-mode communication device, comprising: at the multi-mode communication device, measuring at least one parameter associated with an interaction between a first network and the multi-mode communication device, wherein the parameter includes a coverage status of the first network at the multi-mode communication device, a signal strength at the multi-mode communication device, a Quality of Service support level of the first network at the multi-mode communication device, or a velocity of the multi-mode communication device; and in response to measuring the parameter, selecting a scanning rate of the multi-mode communication device for a second, different network that interacts with the multi-mode communication device, wherein selecting the scanning rate of the second, different network comprises decreasing the scanning rate when the velocity is lower than a predetermined threshold, or increasing the scanning rate of the second, different network when the signal strength is lower than a second predetermined threshold; wherein the first network and the second, different network have independent synchronization procedures.
