  • Method and apparatus for resolving paging monitoring conflicts in multimode wireless equipment
    Patent number: 8634383
    Abstract: A multimode wireless access terminal is configured to operate in idle mode while registered with a plurality of radio access technologies, for example, a TD-SCDMA network and a WCDMA network, and monitor paging messages, with a reduced likelihood of paging conflicts and missed calls. If the paging conflict is seen at a particular cell, then a cell reselection to another cell may be utilized to change the cell and avoid the conflict. Because the probability of a paging conflict is small due to the short duration of paging indicator messages, the access terminal may have very infrequent paging indicator monitoring conflicts, and when conflicts actually do occur, it is very likely that the UE will find a neighbor cell without conflict.

  • REDUCED USER EQUIPMENT MEASUREMENT FREQUENCY
    Publication number: 20140003259
    Abstract: A user equipment may save power and improve performance by reducing the frequency of cell measurement by the UE. A UE may extend the time between measurements of signal strength of serving and/or neighbor base stations. The frequency for the measurements by the UE may be based on signal strength of one or more neighbor base station and/or the mobility of the UE. The time between measurements may be extended when the signal strength of the one or more neighbor base stations fails to meet a threshold value.

  • USER PRESENCE DRIVEN POWER SAVING IN TIME DIVISION SYNCHRONOUS CODE DIVISION MULTIPLE ACCESS
    Publication number: 20140003311
    Abstract: A user equipment (UE) may save power by reducing certain battery draining activities when a user is not close to or not using the UE. The UE may skip inter-radio access technology measurements to conserve battery life. The UE may also extend a paging periodicity when the battery power is low and/or when a sensor detects UE inactivity or a distant user.

  • POWER SAVINGS FOR INTER-RADIO ACCESS TECHNOLOGY MEASUREMENT
    Publication number: 20130336183
    Abstract: A user equipment may save power and improve performance by dynamically switching between a higher and lower clock speed based on the timing of inter-RAT measurement. When a user equipment (UE) is not performing an inter-RAT measurement, the UE uses a clock speed lower than the clock speed associated with inter-RAT measurements. This power saving mode associated with the lower clock speed implementation may be maintained as a default mode when the UE is not performing inter-RAT measurements. The UE may use the higher clock speed when a particular processor power is specified for inter-RAT measurement.

  • Method and system for performing multi-stage virtual SIM provisioning and setup on mobile devices
    Patent number: 8606232
    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.

  • Measurement and handover of dual USIM mobile terminal
    Patent number: 8594670
    Abstract: Certain aspects of the present disclosure relate to a method for efficient measurement and handover of a mobile terminal with multiple USIMs. According to one aspect, a source Node B may initiate calls with first and second subscriber identities associated with a UE that supports multiple subscriber identities and transmit a request for a measurement report to the UE, the request specifying the first subscriber identity. The subscriber identities may be associated with a UE by association with an International Mobile Equipment Identity (IMEI). The source Node B may determine to handover the calls for the first and second subscriber identities to a target Node B based on the measurement report. The source Node B may transmit handover commands to instruct the UE to handover calls for the first and second subscriber identities to the target Node B.

  • Method and apparatus for power efficient idle operation in a dual SIM CDMA EVDO mobile station
    Patent number: 8542666
    Abstract: Methods and apparatus for configuring and scheduling paging intervals for a mobile station (MS) having multiple subscriber identity modules (SIMs) to be aligned are provided. The MS having multiple SIMs may operate in a network via a particular radio access technology (RAT), such as Code Division Multiple Access (CDMA) EVDO (Evolution-Data Optimized). By having aligned paging intervals, the MS may wake up only once during the paging cycles for the various SIMs rather than waking up multiple times, thereby reducing power consumption of the MS during idle mode compared to a conventional MS with multiple SIMs.

  • METHOD AND APPARATUS FOR IRAT MEASUREMENT WHEN IN TD-SCDMA CONNECTED MODE
    Publication number: 20130223428
    Abstract: When a user equipment (UE) is operating in connected mode in a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) network all time slots may be allocated to communications, leaving insufficient time for the UE to perform measurement of neighboring radio access technologies (RATs). The UE may select one out of every N number of transmit time intervals (TTIs) to halt regular communication and reserve that TTI for purposes of inter-RAT measurement.

  • IRAT MEASUREMENT METHOD WHEN IN TD-SCDMA CONNECTED MODE
    Publication number: 20130223239
    Abstract: When a user equipment (UE) is operating in connected mode in a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) network all time slots may be allocated to communications, leaving insufficient time for the UE to perform measurement of neighboring radio access technologies (RATs). When the UE moves out of TD-SCDMA coverage, it may report to the base station and receive an instruction to switch into time division multiplexing (TDM) mode and to perform inter-RAT measurement while in TDM mode.
