  • Publication number: 20130107774
    Abstract: Certain aspects of the present disclosure present methods and apparatus for selecting a power saving mode for a mobile station (MS) in a wireless network. The power saving mode may be selected based on the traffic that is observed at the MS in a predefined duration. Once low overall data traffic is observed, the device may enter a first low power state. If data traffic of a particular type (e.g., not for management or maintenance purposes) is not observed for a predetermined duration, the device may enter a second low power state (deeper than the first low power state).

  • Patent number: 8385261
    Abstract: Methods and apparatus for setting the connection identifier (CID) mask length of a Hybrid Automatic Repeat-Request (HARQ)-MAP or a SUB-MAP pointer information element (IE) in a compressed downlink map (DL-MAP) of an orthogonal frequency-division multiple access (OFDMA) frame are provided in an effort to reduce the number of false indications in the CID mask, while also striving, as a secondary concern, to reduce the CID mask length. In this manner, an individual mobile station (MS) may not waste processing, battery power, or time interpreting a HARQ-MAP message or a sub downlink/uplink map (SUB-DL-UL-MAP) message that was not intended for this particular MS. For some embodiments where the CID mask length is set to be small, the control overhead (i.e., the size of the HARQ-MAP or the SUB-MAP pointer IE) may be decreased, and more of the OFDMA frame may be available for data traffic.

  • Publication number: 20130044731
    Abstract: Methods, systems, and devices are described for utilizing proactive feedback information during a handover of a mobile device from a source base station to a target base station. The mobile device may transmit handover messages to the target base station that includes feedback status information, which may include automatic repeat request (ARQ) information elements in some embodiments. The target base station may request that the source base station transmit packets to the target base station based on the received feedback status information. The source base station may transmit handover messages to the mobile device that include feedback status information in some embodiments. Some embodiments may provide for fast resumption of data transmission by utilizing the proactively sent feedback status information from a mobile device to a base station during handover. Some embodiments may reduce the bandwidth for transferring unnecessary data between base stations.

  • Publication number: 20120252411
    Abstract: Disclosed is an apparatus, system, and method to continuously authenticate a user of a mobile device. The mobile device includes a user interface, a transceiver, a microphone, and processor. The processor continuously samples a user's voice from the microphone during a call by obtaining voice snippets on a pre-defined periodic basis or on a random basis. The processor further compares the sampled voice from the microphone to a stored voice to authenticate a valid user, wherein if the sampled voice matches the stored voice for a valid user, functionality of the mobile device continues. On the other hand, if the sampled voice does not match the stored voice for a valid user, functionality of the mobile device is locked.

  • Patent number: 7983663
    Abstract: When an incoming call is received or an outgoing call is placed, a phone number associated with the call is identified. The phone number is compared to a set of phone book entries corresponding to subscriber-designated phone entries and special phone book entries. If the phone number is identified as corresponding to a special phone book entry, call processing continues according to a field type designated by the selected phone book entry.

  • Publication number: 20100311402
    Abstract: A system and method for providing updated rules governing the switching of enabled provisioning data supporting a wireless service contract. A mobile device may be initially programmed with a profile data table and priority list index data table to automatically enable provisioning data supporting one of the plurality of service providers stored in a VSIM internal memory unit to conduct a wireless communication when certain operational parameter values are satisfied. The profile data table and priority list index data table may be automatically updated in response to a variety of triggers. The profile data table and priority list index data table may be stored remotely. Operational parameters regarding each call request are collected and transmitted to a remote service contract selection server. The selection of an optimal service provider account may be made remotely in the service contract selection server and transmitted back to the mobile device.

  • Publication number: 20100311391
    Abstract: A system and method for provisioning a mobile device with user preferences and settings. The user preferences and settings may be default preferences and settings selected by the various applications loaded onto the mobile device or previously user preferences and settings selected by a user. User selected preferences and settings may be stored in a remote server memory. The preferences and settings may be retrieved by new mobile device. The preferences and settings stored in the remote server memory may contain triggers which initiate a connection with various third party servers. In response to the trigger, various third party servers may transmit further instructions to the mobile device which allows the mobile device to complete the restoration of the user's preferences and settings.

  • Publication number: 20100232309
    Abstract: Certain embodiments of the present disclosure present methods and apparatuses that enable a mobile station (MS) to selectively reject downlink (DL) data during idle mode. The MS may determine whether to reject the pending DL data based on information about the data. This information may be provided by a base station (BS) that is part of the access service network (ASN) that is retaining the DL data. The information provided by the BS may, for instance, include service flow information related to the pending DL data. In certain embodiments, the information may include one or more internet protocol (IP) packets that are part of the pending DL data.

  • Publication number: 20100189070
    Abstract: The present disclosure proposes a method for incorporating a procedure of adding/changing a service flow of a mobile station into a handover process in order to avoid problem that the mobile station can handover to a neighbor base station that do not support the requested service flow operation. Furthermore, the proposed disclosure can reduce the processing delay by combining the handover process of the mobile station and the procedure of adding/changing the service flow.

  • Publication number: 20100105378
    Abstract: A method for facilitating dynamic service-based system selection and determination may be implemented by a communications device. The method may include presenting system selection options to a user based on information that is received about Network Access Providers (NAPs) and Network Service Providers (NSPs). The method may also include receiving user input about the system selection options. The user may be permitted to provide input about specific services offered by specific NSPs. The method may also include determining user preferences regarding system selection based on the user input. The method may also include creating a preferred roaming list (PRL) based on the user preferences. The method may further include using the PRL to scan for available networks and channels and to find serving systems.

  • Publication number: 20100067434
    Abstract: Methods and apparatus for using network topology and coverage information from one radio access technology (RAT) network to assist acquisition of another different RAT network for a multi-mode mobile station (MS), such as acquiring a WiMAX (Worldwide Interoperability for Microwave Access) network based on topology and coverage information about a 3G (Third Generation) network and vice versa, are provided. Base station (BS) acquisition assisted in this manner may provide for quick restoration of a previously interrupted or deactivated network service, while decreasing the power consumption of the multi-mode MS during a power savings state because periodic scanning and registration need not occur.
