Patent ID: 8867419

Claim:
A method for operating a communication device communicating with a wireless network, comprising: in a power save mode where a communication subsystem of the communication device has been deactivated for a first period beginning at a first instance, re-activating the communication subsystem, executing an action relating to a data link layer connection condition for the wireless network, and then de-activating the communication subsystem; and for a second period beginning at a second instance, re-activating the communication subsystem, generating and transmitting a frame to a host in the wireless network by the communication device, and then de-activating the communication subsystem, wherein the first period is repeated on a cycle that is based on a first frequency timed to allow the communication device to process a beacon signal that is received at an interval of at most every third beacon signal in a succession of beacon signals from the wireless network; and the second period relates to a frequency of transmission of an Address Resolution Protocol (ARP) request for an Internet Protocol (IP) address for the communication device.
