Summary:To initiate dormancy early, a wireless device receives an IP packet from a wireless network and determines whether the received IP packet is an unsolicited IP packet. An unsolicited IP packet may be declared if the received IP packet causes the wireless device to reactivate from dormancy or is not delivered to an application or service running at the wireless device. The wireless device transitions to dormancy early if the received IP packet is deemed to be an unsolicited IP packet and no other events prevent transition to dormancy. The wireless device may use ( 1 ) a shortened value for an inactivity timer for a predetermined time duration if an unsolicited IP packet is detected and ( 2 ) a nominal value for the inactivity timer thereafter. The wireless device resets the inactivity timer whenever an IP packet is sent or received and transitions to dormancy upon expiration of the inactivity timer.
