Problems solved by technology

Rather, unsolicited IP packets waste system resources because a traffic channel is established and not used to exchange data
Unsolicited IP packets additionally consume battery power and reduce standby time because the wireless device is turned on and ready for wireless communication due to receipt of this IP packet

Embodiment Construction

[0020] The word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any embodiment or design described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments or designs.

[0021] The techniques described herein to identify unsolicited IP packets and initiate sleep early can be used in various wireless networks. For example, these techniques may be used in Code Division Multiple Access (CDMA) networks, Universal Mobile Telecommunications System (UMTS) networks, wireless Local Area Networks (LANs), and so on. A CDMA network may implement a Radio Access Technology (RAT) such as cdma2000 and a networking protocol such as ANSI-41. A UMTS network may implement a RAT such as Wideband-CDMA (W-CDMA) and / or Global System for Mobile Communications (GSM) and a networking protocol such as GSM Mobile Application Part (GSM-MAP). A wireless LAN provides communication coverage for a limited geographic ar...

Abstract

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.

Description

technical field [0001] This application claims priority to U.S. Provisional Application No. 60 / 630,260, filed November 22, 2004, entitled "Method for Reducing the Impact of Receiving Unsolicited IP Packets on a Mobile Station," which is assigned To the assignee of this application, and is hereby incorporated by reference in its entirety for all purposes. [0002] The present disclosure relates generally to communications, and more specifically, to techniques for processing Internet Protocol (IP) packets at wireless devices. Background technique [0003] Wireless communication networks are widely deployed to provide various communication services (eg, voice, packet data, etc.). A wireless device can obtain data services from a wireless network by using IP via an air link interface employed by the wireless network. A wireless device may establish a data session with a network entity and exchange data with other entities coupled to the wireless network via the Internet or som...
