| 20090017825 | METHOD FOR ALLOCATING OF AT LEAST ONE ACCESS POINT TO A MOBILE TERMINAL IN A CELLULAR NETWORK, CORRESPONDING TERMINAL, MOBILE SERVER AND PROGRAMS - A method is provided for allocating at least one access point to a mobile terminal in a cellular network formed by multiple cells each controlled by an access point, wherein the mobile terminals move about. The method includes the following steps: locating a mobile terminal inside a current cell; identifying, using the locating, a target cell with which the terminal is likely to be connected; transmitting in advance to the terminal a target context, comprising at least one identifier of the access point of the target cell; implementing a procedure for connecting said terminal to the access point of the target cell, based on predetermined cell modification criterion. | 01-15-2009 |
| 20090073879 | METHOD OF MANAGING AN INTERFACE COMPRISING MEANS FOR CONTROLLING REMOTE TERMINALS - A method is provided for transmission within a telecommunication system, which includes a plurality of terminals that can exchange data flows therebetween. The method includes at least: a step of comparing a maximum throughput value offered by an interface with a cumulative value of the throughputs of flows that are intended to pass through the interface; and a step of adjusting the throughput of a particular flow following transmission of an adjustment value to a flow-emitting entity, which is executed when the maximum value is less than the cumulative value. The method enables a given terminal to adjust the throughput of a flow even when the flow is generated by a remote terminal. | 03-19-2009 |
| 20090106175 | MANAGEMENT OF APPLICATIVE STREAMS IN MOBILE NETWORKS - A method is provided for constructing at least one decision graph for managing at least one applicative stream assigned to a terminal and set up between the terminal and a correspondent via at least one communication network. The method includes a step of dynamically constructing at least one possible decision graph for the one applicative stream assigned to the terminal, itself including a step of exchanging at least one configuration message between at least two decision modules pertaining to a predetermined set of decision modules. | 04-23-2009 |
| 20090129274 | METHOD FOR THE OPTIMISED MANAGEMENT OF RESOURCES IN A TERMINAL COMPRISING MULTIPLE INTERFACES - A method is provided for the transmission of data flows through multiple interfaces. The method includes: comparing a maximum throughput value offered by an interface with a cumulative value resulting from a sum of the throughputs attributed to the flows effectively travelling through the interface; and switching a flow to another interface when the maximum throughput value offered is less than the cumulative value. The method can be used to redirect data flows to an interface other than the current interface when a congestion is detected in the comparison step and to perform optimum dynamic management of the resources of different interfaces as a function of the operating conditions of the interfaces. | 05-21-2009 |
| 20100189258 | METHOD FOR DISTRIBUTING AN AUTHENTICATION KEY, CORRESPONDING TERMINAL, MOBILITY SERVER AND COMPUTER PROGRAMS - A method and apparatus are provided for early distribution of at least one encryption key intended for securing a communication to be set up on the link layer of a cellular network formed of a plurality of cells, each controlled by an attachment point, between a mobile terminal and a set of attachment points, termed the target attachment points. The includes, for at least one target attachment point: creation of an encryption ticket containing an encryption key, enciphered on the basis of at least one authentication key specific to this target attachment point; receipt of the enciphered encryption ticket, by way of a current attachment point to which the mobile terminal is connected; identification, of a means of deciphering the enciphered encryption ticket, with the aid of the at least one authentication key, making it possible to obtain the encryption key. | 07-29-2010 |
| 20110106959 | METHOD FOR TRANSFERRING A FLOW BETWEEN HETEROGENEOUS ACCESS POINTS - A method is provided for handing off flows. The flow, having a flow identifier, is established between a terminal and a correspondent. The terminal has as many terminal identifiers as access interfaces to access networks of mutually different data technologies. A first execution entity converts a handoff execution order emanating from a decision entity into execution messages by taking into account a hierarchy of execution entities of a current network. After a handoff decision has been taken for a given pair of flow and terminal identifiers, the decision entity sends an execution order to the first execution entity. The first execution entity: selects a mobility protocol from the mobility protocols supported by the execution entities of the hierarchy associated with the current network; selects in the hierarchy at least one execution entity responsible for executing the mobility protocol; and sends to the selected execution entities respective execution messages. | 05-05-2011 |

| 20110122004 | METHOD OF DECODING A SIGNAL IMPLEMENTING A PROGRESSIVE CONSTRUCTION OF A DECODING TREE, CORRESPONDING COMPUTER PROGRAM AND DECODING DEVICE - A method of decoding a data signal includes progressively constructing a decoding tree, implementing at least two iterations of the following steps: selecting at least one child node of a current node belonging to a selection interval; storing the child nodes in a first stack; deleting the current node from the first stack; selecting a new current node from the first stack; and if the new current node is a leaf node, storing the path between the root node and the leaf node, in the second stack, and deleting the leaf node from the first stack; otherwise, return to the step of selecting a child node for the new current node. Moreover, the method assigns a probability of likelihood to the bits of at least one symbol of the data signal, taking account of the paths stored in the second stack, and determines a probabilistic estimation of the signal. | 05-26-2011 |
