Patent number: 9479978Abstract: Embodiments of this disclosure include methods in which a core network controller determines which femtocell base station to handover a cellular device to. Methods include comparing a cell parameter difference provided by a base station with a cell parameter difference provided by the cellular device. The cell parameter difference provided by the base station is the cell parameter difference between the base station and each neighboring base station. The cell parameter difference provided by the cellular device is the cell parameter difference between the base station through which the cellular device is currently associated with to the core network and each neighboring base station. The core network controller compares the cell parameter difference provided by the cellular device with the cell parameter difference provided by the base station. The core network hands the cellular device to the base station when the cell parameter difference provided by each are substantially equivalent.Type: GrantFiled: June 8, 2012Date of Patent: October 25, 2016Assignee: Broadcom CorporationInventors: Rafael Carmon, Alon Shechter

Patent number: 8849336Abstract: A femtocell power control module is operative to: obtain at least one uplink communication characteristic associated with the uplink signals transmitted by the at least one cellular communication device and received by the femtocell base station; estimate, from the obtained uplink communication characteristic, the power level of the downlink signals transmitted by the femtocell base station, as received by the at least one cellular communication device; if the estimated power level of the downlink signals transmitted by the femtocell base station as received by the at least one cellular communication device exceeds a predefined threshold power level, reduce the power level of the downlink signals transmitted by the femtocell base station to a reduced power level.Type: GrantFiled: April 22, 2010Date of Patent: September 30, 2014Assignee: Percello Ltd.Inventors: Rafy Carmon, Yoav Volloch, Sharon Levy, Alon Shechter

Patent number: 8781497Abstract: Passive location determining of a 3G handset is provided. The method may include the following steps: sending a sequence of 3G ‘Pings’ directed at a specified handset over a 3G network; determining the specified handset user identifier and the sewing base station of the specified handset based on reoccurrences of user identifiers responsive of the ping requests, captured from the forward access channel (FACH) of each base station; decoding the FACH of the serving base station responsive to an additional ping, yielding parameters required for receiving uplink dedicated channel (UL DCH); estimating, in each location associated with a base station, a time difference between fastest possible and actual arrival of a signal over the UL DCH sent by the specified handset, wherein the estimating is synchronized to the serving base station; and calculating the location of the specified handset, based on the estimated time differences associated with the locations.Type: GrantFiled: September 29, 2011Date of Patent: July 15, 2014Assignee: Broadcom CorporationInventors: Ilya Degtyar, Alon Shechter, Rafael Carmon

Publication number: 20140155044Abstract: A method and apparatus is disclosed to restrict access services to a communication device. The services may be restricted based upon hardware characteristics, geographic characteristics, user specifications of the communication device and/or specified rules. The method and apparatus may restrict its service to only specific applications suitable for the environment and the time. Upon a request for a service that is now restricted, the method and apparatus may notify an end user that the service was requested. Further, the method and apparatus may notify an originator of the request that the service is not available and may ask for a short message to be delivered to the end user.Type: ApplicationFiled: February 7, 2014Publication date: June 5, 2014Applicant: BROADCOM CORPORATIONInventors: Rafael CARMON, Alon Shechter

Patent number: 8626186Abstract: Control unit within a femtocell base station is arranged to detect a transmission collision situation and resolves it by adjusting the timing of the transmission signal and consequently the frame position gradually over time. The adjustment (or shift) is performed in a slow enough rate such that the User Equipments currently connected (camped) to the femtocell base station remain connected. Additionally, a method is also provided. The method comprises: detecting neighboring base stations; detecting frame boundaries of the transmitting signal of each detected neighboring base station; calculating optimal transmit position; setting transmit position to calculated optimal transmit position; and maintaining optimal transmit position by gradually adjusting transmit position over time.Type: GrantFiled: August 6, 2008Date of Patent: January 7, 2014Assignee: Percello Ltd.Inventors: Rafy Carmon, Alan Carter, Ami Appel, Benny Arviv, Alon Shechter, Stephen Whitakker
