Patent number: 8958405Abstract: An access point that implements operating modes in which beacons may be selectively disabled. Beacons may be disabled when no device is actively associated through the access point. Beacons may be enabled in response to one or more triggers, which may include events such as a client forming an association through the access point following a probe request message identifying the access point. In addition, active beaconing may be triggered by user input or may occur during periodic brief intervals that allow client devices to discover the network identifier for the access point. Selective control of beaconing may lead to more effective wireless communication, particularly in areas where users congregate with computers implementing soft APs for personal networks.Type: GrantFiled: January 29, 2013Date of Patent: February 17, 2015Assignee: Microsoft CorporationInventors: David A.

Patent number: 8825106Abstract: A mobile device may be configured with multiple access point names (APNs) including a roaming APN and a non-roaming APN. After a mobile device determines whether it is roaming, it may transmit a service request with the corresponding APN. The network may then select a profile based on the APN that may include quality of service parameters and other parameters for servicing the mobile device. The profile may be obtained from a local home location register or a remote home location register.Type: GrantFiled: October 25, 2011Date of Patent: September 2, 2014Assignee: AT&T Intellectual Property I, L.P.Inventor: Venson M.

Patent number: 8812050Abstract: One or more short-range base stations in a network environment provide a substantially smaller coverage area than a long-range base station. The coverage area provided by each of the short-range base stations fully resides within or at least partially overlaps with the coverage provided by the long-range base station. Handoffs from the long-range base station to a respective short range base station, and vise versa, can be conditional on any number of one or more factors such as a speed of a mobile device through the network environment, a type of application and/or type of data transmitted over a respective communication link between the mobile device and the long-range base station, presence of one or more radio frequency layers in the network environment, mapping of a location of the mobile device to a speed limit value derived from a geographical map, etc.Type: GrantFiled: May 5, 2011Date of Patent: August 19, 2014Assignee: Time Warner Cable Enterprises LLCInventor: Ahmed Bencheikh

Patent number: 8811367Abstract: Data rate allocation decisions are made for a communications channel. A message is sent on a communication channel such as on a paging channel. The message indicates a forward Effective Radiate Power (ERP) of a pilot signal transmitted. The remote station then determines the received signal strength of this pilot signal, taking into account receiver gains. The path loss may be estimated as the difference between the forward ERP data value received and the detected received pilot power. This transmit power level information is encoded as a digital data word together with the forward path loss information. Upon transmission, the forward path loss estimate as calculated and the output power value can then help determine the amount of excess power available. This is indicative of the amount of dynamic range available in the transmit power amplifier. Coding rates which require a higher dynamic range may be acceptable for use.Type: GrantFiled: December 6, 2005Date of Patent: August 19, 2014Assignee: IPR Licensing, Inc.Inventors: George Rodney Nelson, Jr., James A. Proctor, Jr., John E. Hoffmann, Antoine J. Rouphael

Patent number: 8805377Abstract: A GSM or UMTS mobile telecommunications network is disclosed. In addition to the conventional radio access network comprising macro base station, one or more additional access points are provided. The access point is connected to the network core by an IP transport broadband connection. The access point is configured to appear to the mobile terminal as a conventional base station—that is, it communicates with the mobile terminal using GSM or UMTS transport protocols and does not require any modification to a standard GSM or UMTS mobile terminal. A subscriber may be provided with a designated “home” access point to provide coverage in their premises. Arrangements are described which will tend to reduce the likelihood that reselection to the macro base station while radio coverage is available from the home access point.Type: GrantFiled: May 28, 2009Date of Patent: August 12, 2014Assignee: Vodafone Group PLCInventor: Youssef Chami

Patent number: 8805433Abstract: A methodology and system for performing radio network coverage surveys of multiple site candidates concurrently using one reserved channel based on reverse path signal strength measurements of a signal from a test mobile station transmitter (100) to a plurality of prospective base station receiver sites (200, 200?, . . . ) over a geographical area is presented. The instantaneous position, time-stamp and power of the Transmitter (101) is recorded and stored as it moves along a test route(s). Stationary Test Receiver(s) (201) tuned to the selected channel at each prospective site location (200, 200?, . . . ) save received instantaneous signal strength and, it's time-stamp so they can matched up to the position of the Test Transmitter (101) and used to ascertain received signal strength at each site. Results can be useful for ascertaining optimum site locations, antenna configurations, propagation model tuning, frequency planning, pilot planning and extraction of signal correlation statistics.Type: GrantFiled: February 27, 2012Date of Patent: August 12, 2014Inventor: Steven Ali Al-Shalash

Patent number: 8805366Abstract: A procedure when a mobile station apparatus accesses a CSG cell in which it is unregistered is defined and a procedure based on the definition is performed. A small base station apparatus applied to a mobile communication system, receives a originated call request message including a user identifier and priority information from a camping mobile station apparatus, determines whether or not to permit the originated call request of the mobile station apparatus, based on the user identifier and the priority information, and transmits the determination result to the mobile station apparatus. In addition, the small base station apparatus permits the originated call request, if the user identifier included in the originated call request message of the mobile station apparatus indicates that the mobile station apparatus is registered.Type: GrantFiled: July 16, 2009Date of Patent: August 12, 2014Assignee: Sharp Kabushiki KaishaInventors: Katsunari Uemura, Hidekazu Tsuboi

Patent number: 8798665Abstract: Systems and methodologies are described that facilitate transmitting control information in wireless networks. Portions of bandwidth can be blanked for transmitting control information, and the control information transmitters can utilize beacon symbols to convey the control information. In this regard, interference is mitigated with respect to data transmissions over the control information bandwidth. Selected frequencies of the beacon symbols in a codeword can be used to indicate the control information. The codewords can be encoded with an error control code to provide redundancy for decoding in the presence of some interference.Type: GrantFiled: June 27, 2008Date of Patent: August 5, 2014Assignee: QUALCOMM IncorporatedInventors: Ravi Palanki, Avneesh Agrawal, Alexei Gorokhov, Aamod Khandekar, Ashwin Sampath, Dexu Lin
