Abstract: A method is proposed for optimizing the bit rate of multimedia contents accessible by a plurality of user terminals connected to a radiocommunications network cell. The multimedia contents are stored in the form of a plurality of independent chunks on at least one multimedia contents server associated with at least one contents provider. The method includes the following steps, implemented in a device for optimizing the bit rate: receiving one request to obtain a multimedia description file, sent by a user terminal; obtaining a multimedia description file; modifying the multimedia description file on the basis of a piece of information representing a quality of delivery, delivering a modified multimedia description file; and transmitting the modified multimedia description file to the user terminal.

Abstract: One embodiment relates to a device for controlling an IP core network including at least one router to an external data packet network and at least one switch connected to the router and to at least one base station of an access network. It may comprise a communication module configured to communicate with a mobility management entity of the core network and to receive information therefrom representative of a mobility state and/or an IP connectivity state of a terminal. It may comprise a module configured to update topology information representing connections between the router(s), the switch(es), the base station(s), and registered terminals, and to update at least some of the topology information as a function of the state information. It may comprise a control module configured to control the router(s) and/or the switch(es) with processing rules applied to data streams for the terminals, which are defined from the updated information.

Abstract: A method is provided to control an IP core network, including first and second routers connected to an external data packet network and switches able to connect to a base station of a network for access to the first and second routers. The data packet network is able to send data streams through the IP core network destined for the terminals attached to the base station, at least one data stream currently being conveyed between the external network and at least one terminal. The method includes: establishing a rule for processing a stream by the first router, assigning the second router as backup router for the first router; transmitting to the external data packet network information relating to the assigning of the backup router; detecting an event relating to a failure of the first router; and transmitting to the backup router an established processing rule to be applied.

Abstract: A method is provided for managing at least one connection established between a mobile terminal and an anchor gateway located between a mobile network and a packet-switching network, and being capable of conducting at least one communication session with the packet-switching network. The method includes receiving a management message from a device suitable for managing the at least one connection, the message including at least one piece of information relating to a change in the state of a connection of the mobile terminal, and an identifier relating to the connection; determining the need for a new connection by analyzing the at least one current connection at least according to the received information; once it has been determined that the need for a new connection exists, triggering the transmission of a request to establish a new connection between the mobile terminal and a new anchor gateway according to the analysis.

Abstract: The invention relates to a method for transmitting a message for updating associations between at least one first address and one second address of a mobile terminal, implemented by a mobile terminal attached, by a plurality of first addresses, to first devices of at least one first packet-switching mobile communication network, said first devices being capable of directing a plurality of communication flows toward the mobile terminal, the method including: a step of obtaining a second address when the mobile terminal is attached to a second device of a second network; a step of generating a group update message, including individual information relating to the plurality of first devices, and information relating to the second device; a step of transmitting the group message to a management device previously associated with the mobile terminal and capable of generating and transmitting individual update messages, from the group update message, to the first devices.

Abstract: A method and apparatus are provided for activating a communication terminal situated in a wireless communication network including a plurality of access nodes. The method includes: receiving, by an access node of the communication network, termed an anchor access node, at least one datum to be transmitted to the communication terminal; identifying, by the anchor access node, at least one access node to which the communication terminal was previously attached, termed a last known access node, on the basis of the datum to be transmitted; and transmitting to the at least one last known access node at least one activation datum destined for at least one communication interface of the terminal, making it possible to activate the terminal.

Abstract: 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.

Abstract: This invention concerns a telecommunication system SYST including: a mobile transmitter/receiver ERM, a number of access points PA1i and PA2j, each capable of communicating with the mobile transmitter/receiver ERM situated in a coverage area ZA1i or ZA2j of the access point considered, and a communication network NW1 authorizing communications between said access points. The system according to the invention includes at least one mobility manager GM capable of determining, based on operating conditions of the access points, with which access point the mobile transmitter/receiver ERM should establish a communication. In the system according to the invention, a change in access point may not be carried out at the sole initiative of a mobile transmitter/receiver ERM, but is, on the contrary, carried out after analysis of an environment specific to said mobile transmitter/receiver ERM by the mobility manager GM.
