Abstract: The invention relates to a mobile station apparatus in a communication system. The communication system comprises a plurality of base stations for providing mobile communication service within a covered communication area. The mobile station apparatus comprises a memory for recording a predetermined access control class and determining which base station the mobile station apparatus is allowed to camp on for conducting mobile communication service, a battery for providing electrical power, a control program, and a power detector for detecting the current power of the battery, so that when the power detector detects that the power is lower than a predetermined low power watermark, the power detector issues a trigger signal. When the control program receives the trigger signal, the control program overwrites the predetermined access control class, so as to allow the mobile station apparatus to conduct mobile communication service through other base stations in the communication area.

Abstract: Methods and apparatus for expressing two or more extended information elements (IEs) of a MAP message using a single Extended or Extended-2 Downlink Interval Usage Code (DIUC) or Uplink Interval Usage Code (UIUC) in an orthogonal frequency-division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) frame are provided. This enhancement, called extensible Extended IE mapping, allows the WiMAX network to include more IEs into the DL-MAP and UL-MAP messages as the IEEE 802.16 family of standards evolves. Without this enhancement, all of the new IEs may most likely have to be included in the data bursts, and a user terminal (e.g., a mobile station) cannot decode these data-burst IEs unless the user terminal receives the Downlink Channel Descriptor (DCD) message(s).

Abstract: A method and an apparatus for determining whether an object is moved are provided. The object is disposed in a communication system having many base stations. The apparatus includes a receiver, a controller, and a warning device. During a predetermined period, the apparatus respectively receives and measures signals from each of the base stations to derive a first average value. Meanwhile, a tolerable probability value is inputted. According to the tolerable probability value and the first average value, the apparatus gets a tolerable range. Next, the apparatus continues to receive and measure signals to derive a second average value. Finally, the apparatus determines whether the object is moved in accordance with the second average value and the tolerable range. If moved, the apparatus sends out a warning signal.

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: A method of locating a mobile station that is turned off. The method includes turning off the mobile station while keeping a battery of the mobile station intact in the mobile station. The mobile station enters a soft power-off mode after the mobile station has been turned off if the battery of the mobile station has sufficient energy. The mobile station receives paging request messages from at least one base station and the mobile station measures RSSI levels for received paging request messages. The mobile station then selects a current base station for which the mobile station measures a strongest RSSI level. The mobile station handshakes with the current base station to enable the mobile station to camp on the current base station. Next, the mobile station reports its location to the current base station and the current base station informs authorities of the location of the mobile station.

Abstract: 27A central database is provided on an external device, such as a personal data assistant (PDA), that is used for local phone number translation. A communications link is provided between a mobile telephone and the central database to allow accessing and indexing of the central database. The mobile telephone obtains identification information from a base station upon which the mobile telephone is camped. The communications link is used to extract local phone number translation information from the central database by indexing with the identification information to obtain corresponding local phone number translation information. The mobile telephone then provides local phone number translation using the local phone number translation information.

Abstract: Techniques, systems and methods for concurrent data and signaling for WiMAX handover are disclosed herein. The serving base station may receive a handover request message from a mobile station and transmit a parameter to the mobile station to indicate a time to suspend a first set of one or more service flows between the serving base station and the mobile station during a handover procedure and continue data exchange between the mobile station and the serving base station for a second set of one or more service flows during the handover procedure. The proposed techniques reduce the service suspension time during the handover procedure.
