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: 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.

Abstract: A cellular device connects with a network of base stations. Each base station covers a corresponding service area, and broadcasts unique identifying information in a standard manner. A portable computing platform is used as a POI database and server for the cellular device, and establishes a communications link with the cellular device. A trip scheduler is provided in the cellular device that interfaces with the POI database server over the communications link to enable a user to extract POI data from the POI database. The POI data includes a POI identifier for a POI, and a related base station identifier that uniquely identifies a target base station having a service area that covers the POI. The cellular device monitors base stations to determine when the cellular device enters into the service area of the target base station, and then provides an alert to the user indicative of the POI.

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: A method for receiving public broadcast services with a wireless device compatible with the Global System for Mobile communications (GSM) protocol is disclosed. The method includes performing a radio frequency (RF) scan on all frequencies in at least one predetermined frequency band to identify all possible Broadcast Control Channels (BCCHs), measuring Received Signal Strength Indicator (RSSI) levels for each BCCH, and sorting the BCCHs according to the corresponding RSSI levels. The wireless device next selects a BCCH having a strongest average RSSI level and camps on a cell corresponding to the selected BCCH. The wireless device is then able to receive GSM public broadcast services from a mobile phone network operating the selected BCCH irrespective of whether the wireless device subscribes to the mobile phone network.

Abstract: Methods and systems are described for using location-based information to determine whether to perform a ranging procedure. A change in location of a device is identified. The identified change in location represents the distance the device has moved during an interval between ranging procedures. The identified change in location is analyzed to determine whether the change exceeds a threshold distance. If the change in location does not satisfy the threshold distance, a change in a signal quality metric of the device from the location associated with the previously performed ranging procedure to the current location is identified. The identified change in signal quality metric is analyzed to determine whether the change exceeds a threshold value. If the change in location of the device is less than the threshold distance and the change in the signal quality metric is less than the threshold value, the next scheduled ranging procedure is bypassed.

Abstract: Methods, systems, and devices are described for concurrently performing handoff-related measurements for neighbor cells using multiple input multiple output (MIMO) antenna resources. In one example, a mobile device is in communication with a serving cell. Handoff-related measurements of first wireless signals from a first neighbor cell are performed. The first wireless signals are received at first MIMO antenna resources of a device. Handoff-related measurements of second wireless signals from a second neighbor cell are performed, as well. The second wireless signals are received at second MIMO antenna resources concurrently with the first wireless signals received at the first MIMO antenna resources. The first handoff-related measurements and the second handoff-related measurements may be performed during a scan interval. A type of handoff-related measurement to perform may be determined based on a determined length of the scan interval.
