Abstract:
Methods and apparatus for waking a mobile station (MS) from a power saving mode to receive a media access control (MAC) management message (e.g., DCD/UCD, MOB_NBR-ADV, and SII-ADV) the MS has not yet received. The MS may wake from the power saving mode after detecting a mismatch between a set of media access control (MAC) management message parameters last received by the MS and the information found in an enhanced broadcast control pointer information element (BCP-IE) transmitted in a downlink map (DL-MAP). In this manner, the MS may be prevented from waking up unnecessarily, thereby providing high power efficiency.
Abstract:
Methods and apparatus for indicating a base station's amount of ranging traffic to a mobile station (MS) and for selecting a base station (BS) for performing ranging based on the ranging traffic indication are provided. This notification may occur via a ranging loading parameter, such as a ranging loading factor (RLF) indicating the ratio of used ranging slots to available ranging slots, transmitted as a new TLV (Type-Length-Value) within the Uplink Channel Descriptor (UCD) of a (potential) serving BS or in the UCD of a Neighbor Advertisement (MOB_NBR-ADV) message for a neighbor BS. By selecting a BS with a certain level of unused ranging slots, the MS may exponentially decrease the ranging overhead (i.e., the average waiting time for the ranging procedures) when compared to a conventional MS that does not consider a BS's ranging overload when trying to perform ranging with the BS.
Abstract:
Certain embodiments of the present disclosure relate to methods for reducing power consumption of a mobile device while maintaining QoS of communication links. If the available battery power is below a predefined threshold, then several power-saving techniques may be triggered that increase an air time of the mobile device by shutting down one or more modem hardware components.
Abstract:
Methods and apparatus for reducing power consumption of a mobile station (MS) during layer 3 (L3) peer-to-peer (P2P) communications employing a request/response message pair are provided. To save power, the MS may enter a power saving mode after transmitting a request message and initiating a timeout timer for the message pair, wherein the power saving mode may have an interval available for receiving the response message and an unavailable interval. The timeout timer may be suspended during the unavailable interval and resumed during the available interval such that the timeout timer is effectively lengthened.
Abstract:
Methods and systems for utilizing a multicast/broadcast connection identifier (CID) scheduling message in an orthogonal frequency-division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) frame in an effort to bypass at least a portion of the Media Access Control (MAC) protocol data unit (PDU) parsing of the frame are provided. By bypassing at least a portion of the MAC PDU parsing of the OFDM/OFDMA frame (which may be in accordance with one or more standards of the IEEE 802.16 family of standards), a particular user terminal need not spend a lot of overhead in the CID filtering process, determining which MAC PDUs are intended to be processed by the MAC of that particular user terminal. Furthermore, for certain embodiments, a user terminal may power down related circuitry during the terminal's bypassing time period(s) of the OFDM/OFDMA frame in an effort to save power.
Abstract:
Methods and apparatus for easily and quickly returning to a first radio access technology (RAT) network when handover to a second RAT network is cancelled are provided. The methods and apparatus may involve a mobile station (MS) entering idle mode before handover to the second RAT network is completed and requesting a serving base station (BS) to retain MS service and operational information, as well as service flow state information. In this manner, should handover to the second RAT network be cancelled before completion, a re-entry to the first RAT network may be expeditiously performed using the retained MS information.
Abstract:
The present invention provides a mobile station apparatus. The mobile station apparatus comprises an RF transmitting/receiving module, a display module, a memory comprising an RSSI database, and a control program. When the mobile station apparatus moves along a path comprising plural candidates of communication locations, the control program records a plurality of RSSIs, which are received by the RF transmitting/receiving module from the candidates along the communication locations, and at least one path parameter in the RSSI database, and then according to a predetermined display algorithm, the control program controls the display module to display at least one recorded RSSI and the corresponding path parameter as a reference, based on which the mobile station apparatus selects a communication location candidate for providing the mobile communication service.
Abstract:
An alerting method for recharging a battery of a mobile device. The method includes collecting measured data with the mobile device, comparing the measured data with a statistic model of recharging patterns of the mobile device, determining if it is currently a suitable time for charging the battery of the mobile device according to a predetermined relation in the statistic model, and alerting a user of the mobile device to recharge the battery if it is currently a suitable time for charging the battery of the mobile device.
Abstract:
A method for changing outputting settings for a mobile unit. The mobile unit has a user profile of a user, and the user profile contains a first data and a second data corresponding to first settings and second settings. The method includes monitoring the user's physical status to gather a third data, comparing the third data to the first data and the second data for selecting the outputting settings from the first settings and the second settings, and adjusting at least one output device of the mobile unit by the outputting settings.
Abstract:
A radiation detection method and apparatus thereof for estimating radiation power received by the mobile station. The locations of nearby base stations and the mobile station are obtained from the broadcast system messages and the location service provided by the service provider, and based on the location information, the radiation power is estimated according to the distances between the base stations and the mobile station. In addition, the radiation estimation process also utilizes the radiation power of monitored base stations constantly measured by the mobile station for cell selection to determine the effects of interference. Based on a preset safety value and the estimated radiation power, the radiation detection device of the present invention automatically issues an alert when entering a high radiation environment.
