  • Patent number: 11716212
    Abstract: 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.

  • Publication number: 20220201020
    Abstract: 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.

  • Publication number: 20220038955
    Abstract: 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.

  • Patent number: 8503430
    Abstract: 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.

  • Patent number: 8265036
    Abstract: An apparatus and method for a centrally managed handoff comprising originating a service using a first technology and connecting the service using the first technology; activating a second technology that is different from the first technology; receiving a first request for the handoff from the first technology to the second technology; sending a second request for the handoff from the first technology to the second technology, wherein the second request relates to the first request; receiving an acknowledgement that the second technology is available; implementing the handoff from the first technology to the second technology; and determining that the handoff is successfully implemented before terminating the first technology.

  • Patent number: 8228865
    Abstract: 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.

  • Publication number: 20100284284
    Abstract: An access terminal includes a processing system configured to determine whether a voice over internet protocol (VoIP) communication channel is available. The processing system is also configured, upon entry into a VoIP-enabled communication environment, to provide without manual intervention a first request for one or more VoIP network connection resources to initiate communication between the access terminal and a packet data gateway over a VoIP communication channel. A method and a processing system are also provided for initiating a VoIP service.

  • Publication number: 20100124211
    Abstract: Methods, apparatuses, and systems for reducing an occurrence of a Voice over Internet Protocol (VoIP) call from being disconnected in an Evolution Data Only (EV-DO) system are disclosed. The VoIP call is placed on hold and at least one keep-alive packet is issued to prevent a radio link from disconnecting. The at least one keep-alive packet is issued at least while the VoIP call associated with the radio link is on hold and is configured to reset a dormancy timer for the call at one or more network entities.

  • Patent number: 7593730
    Abstract: 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.

  • Publication number: 20070183394
    Abstract: 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.
