There are a number of techniques for estimating a movement speed of a mobile terminal by means of signalling data. According to these techniques, a position of the mobile terminal is estimated, approximated by the centre of a cell of a base station to which the mobile terminal is connected. To do this, use is made of a Voronoi partitioning of the territory covered by the cells. Each network event is then positioned at the centre of the cell in which it occurs. Such events are time-stamped, enabling a speed to be calculated. However, such techniques have the following limitations specific to Voronoi partitions. This solution goes against these methods, which first require estimating the two positions of the mobile terminal.

Services for detecting and mitigating computer attacks are proposed by some access providers to their customers. However, sometimes a message to request support for the management of attacks issued by a node of a client domain under computer attack is sent to a mitigation server that is unable to process it. Such a request will be systematically rejected and no mitigation action will be implemented. The present solution makes it possible to ensure that no request message issued by a node goes unanswered, even if it is transmitted to a mitigation server that is unable to process it. To this end, when a mitigation server determines that it is unable to process a request message, instead of rejecting this request, it will seek to identify at least one other mitigation server that would be able to process this request message.

Thus, when a second environment is rendered after rendition of the first environment, the user is not projected directly into the second environment. This decreases risk of motion sickness and fatigue due to leaps. Additionally, the user can anticipate the second environment, avoiding a risk of disorientation.

In known implementations of distributed ledgers, all of the transactions linked to a service are archived in nodes involved in the implementation of the service. This makes it possible to verify the authenticity and the integrity of the transactions and to ensure that the service that is provided is compliant. This poses a problem for nodes having limited storage capacities, some ledgers possibly reaching a significant size and ultimately potentially making it impossible for some modes to be able to record new transactions, thus causing a problem in terms of controlling the actual execution of the operations linked to these transactions. The present solution allows some nodes involved in the implementation of a service to be able to empty their local ledgers without this jeopardizing the correct operation of the associated distributed ledger. The transparency and the permanence of the transactions relating to the service are thus guaranteed.

METHOD FOR PROCESSING RADIO-FREQUENCY SIGNALS RECEIVED ON R ANTENNAS, AND CORRESPONDING RECEPTION METHOD, DECODING METHOD, COMPUTER PROGRAM AND SYSTEM
A method of processing radio-frequency signals received on R antennas, and corresponding reception method, decoding method, computer program and system. The method for processing radio-frequency signals received on R antennas, where R≥2, includes, implemented by a radio unit: obtaining a frequency representation of the radio-frequency signal received on an antenna, demapping the frequency representations, estimating the transmission channel of the radio-frequency signals and a noise-plus-interference covariance, projecting a vector of R associated complex samples onto a vector of L complex samples, referred to as projected samples, transmitting at least one item of control information and the vector of L projected samples to a base band processing unit, and the following, implemented by the base band processing unit: receiving the item of control information transmitted by the radio unit, receiving the vector of L projected samples transmitted by the radio unit, equalising the L projected samples, processing the equalised symbols.

A method and a device for characterizing a user, in particular a user of a device and/or a service in the field of computer security. The characterization method includes: a comparison of first data associated with a first sound object spatialized at a first location by a user interface of a communication terminal and second data received following the reproduction of the first spatialized sound object, the second data being based on a second spatialized sound object perceived at a second location. The comparison triggers, in the event of a positive result, a characterization of the source of interaction as being a suitable user. Thus, errors in characterizing a user as a suitable user, in particular a human user, are reduced because existing sound and speech recognition systems are not able to select a sound in a spatialized sound environment, i.e. a 3D audio scene.
A method for parameterizing a terminal device, able to transmit and receive data on a communications network organized into network slices. The method is implemented by a network administration entity able to communicate with the terminal device via the network. The method includes: following receipt of a registration request or a data session establishment request from the terminal device, obtaining at least one slice identifier associated with said terminal device, determining a maximum number of slices accessible to said terminal device, and if the determined maximum number of slices is lower than the number of identifiers obtained, transmitting a response message to said received request to the terminal device. The response message indicates rejection of the request and/or a list of identifiers from among the obtained slice identifiers.
A method for processing a digital model of a system comprising entities is described, the digital model comprising a structural graph representing the entities of the system by interconnected nodes and an over-graph corresponding to an abstraction of the structural graph and comprising nodes representing sets, at least one of the nodes of the structural graph being associated with at least one of the nodes of the over-graph. The method is implemented by an electronic device and includes determining a node of the over-graph capable of creating an overload; generating an indexing node representing a sub-set of the set represented by the determined node, the sub-set inheriting properties from the set and comprising at least one additional characteristic; associating the indexing node and the determined node; identifying nodes of the structural graph which are directly associated with the determined node and which share the at least one additional characteristic; and associating the identified nodes with the indexing node.
METHOD FOR PROCESSING A TELEPHONE CALL IN A COMMUNICATION NETWORK, METHOD FOR TRANSMITTING, METHOD FOR RECEIVING SUCH A CALL, CORRESPONDING DEVICES, SYSTEM AND COMPUTER PROGRAMS
A method for processing a call set-up request message transmitted by a calling terminal to a called terminal in a communication network, the network including an item of communication equipment configured to receive the message. The method is implemented at the item of communication equipment and includes: updating an information field of the message by inserting additional caller identification information obtained from at least one first data table; and transmitting the updated message to the called terminal.

METHOD FOR COMMUNICATION BETWEEN A BASE STATION AND AT LEAST ONE ITEM OF COMMUNICATION EQUIPMENT, BASE STATION, COMMUNICATION EQUIPMENT AND COMPUTER PROGRAM CORRESPONDING THERETO
A method for communication between a base station and at least one item of communication equipment attached to the base station. The method includes: obtaining at least one first value of a quality of a radio uplink or downlink between the base station and one of the items of equipment, referred to as client equipment, allocating radio resources to the item of equipment in accordance with an allocation scheme implementing a first radio quality of service configuration, if at least one current value of a quality of the radio uplink or downlink between the base station and the item of client equipment is associated with a radio link quality level lower than the at least one first uplink or downlink value, respectively, allocating radio resources to the item of equipment attached to the base station in accordance with an allocation scheme implementing a second radio quality of service configuration.
