Abstract
Methods and apparatuses for operating a wireless mobile station configured to communicate with a wireless access point are described. A sleep state may be maintained in which a radio frequency (RF) radio in the wireless mobile station is in a low power state. The wireless station may use a plurality of sleep states, each with a different sleep timer period based upon recent network activity. In one embodiment, a device may have two sleep states with two sleep timers, and in another embodiment a device may have three sleep timers for three sleep states. The first sleep time may be started for a first sleep state and to determine when to awake the device to determine whether there is any network activity. The device then determines whether a first period of network inactivity has occurred and, if so, it starts a second sleep timer for a second sleep state in response to determining that the first period of network inactivity has occurred. The method can further include determining whether a second period of network inactivity has occurred and, in response to determining that a second period of network inactivity has occurred, the device starts a third sleep timer for a third sleep st…
