  • Publication number: 20190327671
    Abstract: 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.

  • Patent number: 9294713
    Abstract: 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).

  • Patent number: 8537749
    Abstract: Within a user device to which a radio communication network infrastructure transmits data carried by a sequence of frames broadcast to the user device, each frame comprising a first section comprising data and a second section comprising redundancy information associated with the data of a predetermined number B of previous frames in the sequence, a number of consecutive lost frames is compared to a threshold dependent on the number B of previous frames with which said redundancy information is associated and encoding parameters that generate said redundancy information, and a request to retransmit at least one of the consecutive lost frames is sent to the radio communication network infrastructure if the number of consecutive lost frames exceeds said threshold.

  • Patent number: 7054527
    Abstract: 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.

  • Patent number: 6736554
    Abstract: 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.

  • Patent number: 5780120
    Abstract: A method of preparing faces of a laser based on III-IV compounds, the method comprising the following operations:1) the faces of the laser are opened;2) said faces of the laser are placed in an enclosure in which there obtains a pressure of about 10.sup.-7 mbar to about 10.sup.-8 mbar, and they are subjected to a step of cleaning by irradiation with a pulsed laser; and3) the same pulsed laser is used to ablate a target so as to subject said faces to a passivation operation whereby silicon Si or gallium nitride GaN is deposited thereon by the pulsed laser deposition method until a thickness is obtained lying in the range 2 .ANG. to 20 .ANG..
