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: 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.

Abstract: A method is provided for managing decisions between a central manager and at least one terminal in an architecture of networks distributed and prioritized according to N levels, with N?2. The central manager is included in a level of rank N. The terminal is included in a level of rank 1. The method includes a step of distributing a decision tree constructed by the central manager and supported by the architecture.

Abstract: A telecommunications system provides mobile internet protocol related communications services to mobile nodes via a plurality of access networks that each include an access gateway, a mobility manager operable to receive link quality messages from the mobile nodes providing an indication of a currently available link quality from an access network with which the mobile node is currently affiliated. The mobility manager is also operable to receive application server messages from the application server for managing the communications service with respect to the communications session level. The mobility manager directs a change of affiliation of a first mobile node between one of a first of the access networks and a second of the access networks to the other of the first and second access networks, or a change of communications session level of the first mobile node.

Abstract: A telecommunications system provides mobile internet protocol related communications services to mobile nodes via a plurality of access networks. A mobility manager directs a change of affiliation of a first mobile node between the access networks, or a change of communications session level of the mobile node, in accordance with the congestion state of the access networks, the link quality currently experienced by the mobile node, applications server messages and the level of service quality to which the first mobile node has subscribed. A quality of service for communications sessions of a mobile nodes can be maintained even on unregulated access networks, such as Wireless Local Area Networks (WLAN) independently of a Mobile IP v4/v6 stack. Moreover congested access networks can be decongested by controlling the communications bandwidth used by the mobile nodes.

Abstract: Different portions of a header of each packet containing protocol data are analyzed in succession from different gate registers of the TRIE memory. As a packet arrives, its header is stored in a buffer memory and a first portion of the stored header is analyzed. Each analysis of a portion of header produces either the forwarding reference associated with the packet or an intermediate reference containing a first code, making it possible to locate at an arbitrary location of the buffer memory a next portion to be analyzed, and a second code, making it possible to locate at an arbitrary location of the TRIE memory a gate register from which this next portion is to be analyzed. Having analyzed the first portion of a stored header, the subsequent portions thereof are analyzed in accordance with the first and second codes contained in the intermediate references produced in succession until the forwarding reference is produced.
