Patent number: 9319995Abstract: The present invention relates to a method and an apparatus for controlling the transmit power of a mobile station (UEX) served by a small cell (C1). In accordance with an embodiment of the invention, the method comprises the steps of, and the apparatus comprises means for, detecting a measurement event anticipating the forthcoming fulfillment of a handover condition towards a neighboring macro cell (C2) by the mobile station, and thereupon step-wise increasing the transmit power level of the mobile station so as to reach a transmit power target (P_Target) when the handover condition is eventually fulfilled by the mobile station. The transmit power target is for compensating for an estimated downlink path loss for the mobile station in the macro cell.Type: GrantFiled: March 14, 2013Date of Patent: April 19, 2016Assignee: Alcatel LucentInventors: Holger Claussen, Rouzbeh Razavi

Publication number: 20110219443Abstract: The invention is directed to an inter-host signaling protocol, referred to herein as Knock-On Protocol (KOP), for establishing in a secure manner a connection with a host behind firewall. Some embodiments of the invention are directed to a Knock-On Feature (KOF) used in intermediate firewalls or network address translators to enable connection establishment through the FW or NAT to hosts behind the FW or NAT. Advantageously the KOF may include a prefix-based protection feature to protect against address spoofing used in a message flood attack.Type: ApplicationFiled: March 5, 2010Publication date: September 8, 2011Applicants: ALCATEL-LUCENT USA, INC., ALCATEL-LUCENT IRELAND LTD.Inventors: Karl Georg Hampel, Davide Cherubini, Rouzbeh Razavi
