Patent number: 9210575Abstract: The present invention relates to a method for securing a radio communication link establishment in a radio communication network comprising a local network and a secured network. The local network comprises at least a first terminal and a second terminal and at least the first terminal is capable of communicating with the secured network. The radio communication network implements layered protocol functions, comprising at least Layers 1, 2 and 3, the terminals being identifiable by their Layer 2 and 3 addresses. The secured network comprises a database comprising address correspondence information between Layer 2 and 3 addresses of terminals. In the method the first terminal authenticates itself with the secured network and then by using the Layer 3 address of the second terminal, obtaining the address correspondence information provided by the database and thereby determining the corresponding Layer 2 address of the second terminal.Type: GrantFiled: January 8, 2013Date of Patent: December 8, 2015Assignee: Apple Inc.Inventors: Pierre Lescuyer, Thierry Lucidarme

Patent number: 9131415Abstract: A mobile first terminal (1) has a call in progress with a second terminal (2) under a first communications service via a base station (10) of the access network of a first subsystem. A condition for transferring the call to a base station (20) of the radio access network of a second subsystem is detected in a radio network controller (11) of the first subsystem. A core network switch (12) which is linked to the radio network controller (11) of the first subsystem is informed of said detection of a call transfer condition. If the second subsystem cannot process the call under the first communications service, a service change is requested so that said call can continue under the second communications service.Type: GrantFiled: November 15, 2004Date of Patent: September 8, 2015Assignee: Alcatel LucentInventors: Frank Scott, Pierre Lescuyer, Philippe Cassuto, Susan Martin, Michael Thomas, Carole Tomatis

Publication number: 20080254807Abstract: The access network for a cellular wireless communication system includes home gateways (5) placed in customer premises and providing wireless links to mobile stations, and a private operator network (20). The private operator network includes base station control units (22), security gateways (21) and a home gateway management server (26). The security gateway has a secure interface for establishing secure tunnels for communication with home gateways through a broadband public network (6). Each home gateway communicates via the security gateway with the home gateway management server of the private operator network to obtain an address of one of the base station control units allocated to the home gateway. The base transceiver station included in a home gateway interfaces with the allocated base station control unit via the private operator network and a secure tunnel with the security gateway.Type: ApplicationFiled: October 2, 2006Publication date: October 16, 2008Applicant: Alcatel LucentInventors: Philippe Duplessis, Pierre Lescuyer

Patent number: 7324529Abstract: The invention concerns the dynamic reservation of resources according to the RSVP protocol for transmitting an application flow in the form of first packets between a radio terminal and a remote unit interconnected via a first IP network and a cellular radio communication system. The cellular radio communication system uses a second IP network, or even a third IP network, in its core network. According to the invention, the dynamic reservation of resources in the first IP network is completed by a second dynamic reservation of resources in the second IP network, and where necessary a third dynamic reservation of resources in the third IP network. For this, transmission elements of the cellular radio communication system perform the association between the tunnel identity used for transmitting the first packets of the application flow and the parameters assigned to each RSVP session.Type: GrantFiled: June 3, 2002Date of Patent: January 29, 2008Assignee: Nortel Networks LimitedInventors: Thierry Lucidarme, Pierre Lescuyer
