Patent number: 11191014Abstract: There is described therein a method of roaming between 5G networks operator for selecting a network operator in a visited country when a mobile network user exits an area covered by a home network operator to enter the visited country covered by a plurality of visited network operators. This method of roaming is based on the concordance between the VNF supported by the visited country network and the network profile of the user. The network profile of the user embeds both the functions commonly chained in his home network to deploy the services corresponding to his usage and the functions required in the visited country network to perform the services desired by the user. Therefore, by matching this profile with VNF capabilities deployed by a network the invention allows a better user satisfaction in roaming situations providing them with the most suitable network.Type: GrantFiled: November 29, 2017Date of Patent: November 30, 2021Assignee: ALCATEL LUCENTInventors: Bessern Sayadi, Sylvaine Kerboeuf

Patent number: 9294713Abstract: The invention related to a method for transmitting video contents from a server to a terminal of a user within service periods (S) of a radio transport channel, each video content being encoded by using scalable codec technology for integrating a scalable codec base layer (b1, b2, b3, b4) and at least one enhancement layer (e1, e2, e3, e4), each service period (S) comprising: —at least one multiplexed time-sliced radio burst (A, A?) comprising at least a part of the base layers (b1, b2, b3, b4); —several multiplexed time-sliced radio bursts (B, C, D, E) comprising the enhancement layers (e1, e2, e3, e4) and the eventual remaining base layers (b1, b2, b3, b4); said method enabling to permute, between two consecutive service periods (S), the transmission order of the enhancement layers bursts (B, C, D, E).Type: GrantFiled: January 21, 2011Date of Patent: March 22, 2016Assignee: Alcatel LucentInventors: Marie Line Alberi-Morel, Sylvaine Kerboeuf

Patent number: 7054527Abstract: In an optical or optoelectronic module (1) an intermediate medium (4, 10) whose optical index decreases with temperature is introduced into the optical path (7) between a laser diode (9) and an optical fiber (5). This compensates, by passive means, the power losses of the laser emission due to the increase in operating temperature by improving the transmission between the diode (9) and the fiber (5). The intermediate medium (4, 10) is preferably deposited in the form of a capsule (10) enveloping the diode (9) and the end of the fiber (5). This achieves, by passive means, a transmitted power that is independent of the operating temperature.Type: GrantFiled: January 17, 2002Date of Patent: May 30, 2006Assignee: Avanex CorporationInventors: Bruno Fernier, Sylvaine Kerboeuf, Jean-Marc Rainsant, Francois Boubal, Alwin Göth, Joachim Scherb

Patent number: 6736554Abstract: In an optoelectronic module (1) comprising a plastics material package (2) accommodating a base (8) fixed to the package (2) and supporting an optical component (9) coupled by an optical fiber (5) to an optical connector (4) of the package (2), fiber displacements associated with thermal stresses are avoided by mounting the base so that it floats on the package (2) and possibly the connector (4). The floating mounting of the base (8) is obtained by using for fixing the base one or more adhesives (13, 14) having a greater elasticity than the adhesives used to fix each of the two ends (6, 7) of the fiber (5) to the base (8) and the connector (4), respectively.Type: GrantFiled: May 22, 2002Date of Patent: May 18, 2004Assignee: Avanex Corp.Inventors: Sylvaine Kerboeuf, Emmanuel Grard, Claude Artigue, Pierre Jean Laroulandie, Alwin Goeth, Klaus Adam
