Patent number: 11716212Abstract: Methods and systems for providing software applications on a client device with dynamic control over low-latency mode (LLM) operations of the client device. The client device may monitor downlink data packets of a client software application operating on the client device to detect trigger events. The client device may determine operating parameters of the modem based on a detected trigger event and dynamically adjust the low-latency mode of the modem based on the detect trigger event or the determined operating parameters.Type: GrantFiled: December 14, 2020Date of Patent: August 1, 2023Assignee: QUALCOMM IncorporatedInventors: Vinay Melkote Krishnaprasad, Prashanth Haridas Hande, Sandeep Kanakapura Lakshmikantha, Peerapol Tinnakornsrisuphap, Deepak Khandelwal, Ravi Agarwal, Ajit Venkat Rao

Publication number: 20220201020Abstract: Methods and apparatus for dynamic adaption of anti-replay window (ARW) management with enhanced security. According to aspects of the method, pre-ARW block employing a pre-ARW sliding window and an ARW block employing an ARW sliding window are maintained for an associated IPsec security association (SA). A determination is made to whether a received packet passes a pre-ARW check using the pre-ARW sliding window. When it does, the pre-ARW sliding window is advanced, encrypted content in the packet is decrypted, and processing is forwarded to the ARW block which performs an ARW check and advances the ARW sliding window when the ARW check is passed. Packets that do not pass the pre-ARW check may be buffered in queues and subsequently rechecked against the ARW sliding window. Under solutions provided herein, ARW checks and updates are decoupled from the decryption processes, enabling decryption to be performed in parallel and/or offloaded to a hardware accelerator.Type: ApplicationFiled: March 14, 2022Publication date: June 23, 2022Inventors: Ravikumar AIMANGALA NAGARAJA SETTY, Rajakumar CHIDAMBARAM, Balaji CHINTALAPALLE, Deepak KHANDELWAL, Joy DEVASSYKUTTY PULLOKARAN, Joseph Maria Jaison VINCENT SOLOMON

Publication number: 20220038955Abstract: Aspects are directed towards activating out-of-order delivery (OOOD) on a user equipment (UE). An application programming interface (API) on the UE may set one or more configuration parameters for IP flows from the wireless network. The UE may then measure the IP flows from the wireless network, traffic flow templates (TFTs), and/or quality-of service flows (QFI) to identify measured IP flows from the wireless network meet the one or more configuration parameters. The UE may then activate OOOD for the IP flows from the wireless network that meet the one or more configuration parameters.Type: ApplicationFiled: July 22, 2021Publication date: February 3, 2022Inventors: Prashanth Haridas HANDE, Karen Yvonne WEEKS, Ravi AGARWAL, Peerapol TINNAKORNSRISUPHAP, Leena ZACHARIAS, Pulkit HANSWAL, Arnaud MEYLAN, Arvind Vardarajan SANTHANAM, Deepak KHANDELWAL, Yacob COHEN-ARAZI

Patent number: 8503430Abstract: An operational mode of a terminal is dynamically configured to allow the terminal to receive services of interest to the terminal while potentially conserving battery power. The terminal operates in a first mode (e.g., an HRPD-only mode) and monitors only a first radio network (e.g., an HRPD network) for pages from a first data network (e.g., and IMS network) if all services from a second data network (e.g., an ANSI-41 network) of interest to the terminal is obtainable via the first radio network. The terminal operates in a second mode (e.g., an 1X-HRPD mode) and monitors the first radio network and a second radio network (e.g., a 1X network) for pages from the first and second data networks, respectively, if at least one service from the second data network of interest to the terminal is not obtainable via the first radio network. The terminal may dynamically select the first or second mode.Type: GrantFiled: November 21, 2006Date of Patent: August 6, 2013Assignee: QUALCOMM IncorporatedInventors: Reza Shahidi, Deepak Khandelwal

Patent number: 8228865Abstract: Techniques to efficiently search for a WLAN are described. A terminal receives country information from a wireless wide area network (WWAN), which may be a cellular network or a broadcast network. This country information may be a Mobile Country Code (MCC) that is broadcast by the WWAN. The MCC identifies the country in which the WWAN is deployed. The terminal then performs active scan for a WLAN based on the country information received from the WWAN. For the active scan, the terminal determines a frequency channel and a transmit power level based on the country information. The terminal then transmits a probe request on the frequency channel and at the transmit power level determined based on the country information. The terminal may perform passive scan and/or active scan in accordance with a scan setting.Type: GrantFiled: April 7, 2006Date of Patent: July 24, 2012Assignee: Qualcomm IncorporatedInventors: Deepak Khandelwal, Amit Gil, Rotem Cooper

Patent number: 7593730Abstract: A preferred roaming list (PRL) carries system and acquisition records for wireless wide area network (WWAN) systems and wireless local area network (WLAN) systems. New system and acquisition records may be defined for WLAN. The PRL and system and acquisition records may be defined to be backward compatible with TIA-683-C. System and acquisition information for WLAN systems may be stored in the new system and acquisition records, respectively. Information used to perform encryption and/or authentication for WLAN systems may be stored in a separate WLAN authentication profile table. The system record for each WLAN system indicates a acquisition record and a profile record for that WLAN system. A network identifier table may also carry system records and profile records for WLAN systems. The system records carry information used for WLAN system selection and acquisition. The profile records carry information used to perform encryption and/or authentication for WLAN systems.Type: GrantFiled: August 31, 2005Date of Patent: September 22, 2009Assignee: Qualcomm IncorporatedInventors: Deepak Khandelwal, Selvaraj Jaikumar, Nobuyuki Uchida, Rotem Cooper

Publication number: 20070183394Abstract: Techniques for performing automatic call origination for multiple wireless networks are described. A terminal automatically originates a call and supports fallback in case of call origination failure. The terminal selects the most preferred wireless network for the call based on network availability and network selection information. The terminal attempts origination of the call on the selected wireless network. If the call origination fails, then the terminal may select an alternate wireless network based on network availability and the network selection information and may attempt origination of the call on the alternate wireless network. If a VoIP call is preferred over a circuit-switched voice call, then the terminal may first attempt origination of a VoIP call on a packet-switched wireless network. If the VoIP call fails, then the terminal may attempt origination of a circuit-switched voice call on a circuit-switched wireless network.Type: ApplicationFiled: February 3, 2006Publication date: August 9, 2007Inventors: Deepak Khandelwal, Rotem Cooper
