Abstract:
A method and apparatus are provided for managing sessions during which a terminal and a server exchange information blocks organized as a plurality of streams. The method includes storing in a data structure first data determined on the basis of an information block dedicated to signaling and coming from the terminal, the first data identifying the stream that transports the information block, the stream belonging to a session. The method further includes storing second data linked to the first data, the second data being determined on the basis of at least one other information block dedicated to signaling and transported by the same stream, the second data identifying the other stream or streams of the session.
Abstract:
The invention relates to a method of switching over an audiovisual session in a telecommunications network (1) comprising at least one first access network (31) and one second access network (32), an audiovisual session being in progress, during which at least one user terminal (10) attached to the first access network and able to attach itself to the second access network receives from a contents server (61) at least one data stream constituent of an audiovisual content by way of a data stream gateway (41) comprising a first output interface (41S1) to said first access network and a second output interface (41S2) to said second access network.According to the invention, the switchover method comprises the following steps: receiving a request for session switchover to the second access network, emitted following a change of a state of attachment of said terminal; ordering switchover of said audiovisual session from the first output interface to the second output interface at said data stream gateway (41); recovering information related to a context of said audiovisual session switched over to the second interface; ordering evaluation at a contents profiles server (55) of an adaptation of quality, that can be supported by said second interface, of the audiovisual content transmitted for said audiovisual session as a function of said information recovered; and receiving a response on the part of said contents profiles server (55) and requesting updating of said data stream emitted during said audiovisual session to the contents server (61) so as to ensure said evaluated adaptation of quality.
Abstract:
Predefined electrical signals, produced by an electrical equipment in the building during a change of electrical operating state of said equipment, are detected on the building's power supply system. By analyzing each detected electrical signal, tracking data is generated including information relating to the date of detection, the electrical equipment originating the signal and the corresponding change in electrical state. At least one parameter representative of the activity carried out by said person is determined, in the form of a probability of an activity or a type of activity being carried out, based on tracking data generated during a predefined period of time.

Abstract:
A method is provided for communicating between first and second routers, the routers being part of a packet-switched network. The method includes a stage of transmitting data over a pseudowire set up between the first and second routers, the data being transmitted in accordance with a parameter of the pseudowire. The method includes at least one step of sending a modification request message of the parameter at the initiative of one of the two routers, to the other router, and during the stage of transmission over the pseudowire. Also, a method is provided for processing data transmitted over such a pseudowire. The method includes a stage of transmission of data over the pseudowire, the data being transmitted in accordance with a parameter of the pseudowire. The method includes, during the transmission stage, at least one of the routers receiving a modification request message of the parameter of the pseudowire.
Abstract:
A method of communication between a source node in motion and a destination node. The method includes the following steps implemented by the destination node: receiving a packet sent by the source node, said packet including current mobility information relating to the source node; and, for routing at least one response packet intended for the source node: predicting a location geographical area of the source node from the current mobility information relating to the source node contained in said packet received therefrom beforehand, the geographical area thus predicted purportedly being a destination geographical area; at least one step of sending to the destination geographical zone another packet containing said response packet and the destination geographical zone and, if appropriate, passing in transit through at least one intermediate node of a vehicular network.
Abstract:
A method of authenticating an entity by a verification entity, said entities sharing a pair of secret keys X and Y. According to the invention said secret keys X and Y are n×m (n, m>1) binary matrices, said method comprising steps repeated r times (r≧1) of: the entity (1) to be authenticated and the verification entity (2) exchanging binary vectors a and b of n bits respectively drawn at random by the verification entity (2) and the entity (1) to be authenticated and the entity (1) to be authenticated drawing at random a noise binary vector c of m bits, each of said m bits being equal to 1 with a probability η less than ½, and calculating and sending to the verification entity (2) a response vector z of m bits equal to z=aX⊕bY⊕c; the verification entity calculating the Hamming weight (220′) of an error vector e=z⊕aX⊕bY; and then accepting (240′) the authentication if the Hamming weights of the r error vectors e satisfy a relationship of comparison (230′) to a parameter (T, t) that is a function of the probability η. Application to cryptographic protocols for authenticating electronic chips of very low cost.
