A method for access by a communication device to a network connectivity provided by a third party via an operator network. The method includes: sending, to a management device, a request for attachment to the operator network, including an identifier of the third-party; receiving, from the management device, a message containing contact information of a software control gateway controlling access to a network slice allocated by the operator to the third party and associated with the third party identifier, the contact information including a reachability address of the software control gateway or an identifier of the network slice to which access is controlled by the software control gateway, the message inviting the communication device to attach to the software control gateway; requesting attachment to the software control gateway using the contact information; and accessing to the network connectivity via the slice of the operator network allocated to the third party.

Method for managing an attachment of a communication device to an operator network

A method is described for negotiating a contract between two parties in a telecommunications network, as well as devices implementing the method. The method includes distributing, by a first party, a smart contract comprising: a subscription method allowing a second party to distribute a transaction for subscribing to the contract proposal, a method for generating a personalised contract between the parties and requesting their registration in the blockchain, the personalised contract being generated on the basis of parameters included in the transaction, executing the subscription method by a terminal of the second party, the execution triggering the distribution of a transaction comprising parameters representing the acceptance of the contract proposal by the second party, and executing, by a mining device, the method for generating a personalised contract with these parameters.

Method for negotiating a contract between two parties in a telecommunications network and devices implementing said method

A communication device associated with a transmitting entity and including: a first transmitting/receiving module capable of receiving, from the transmitting entity, a query formulated in a predetermined computer language or in a predetermined natural language; a translation module, activated if the query is formulated in the predetermined computer language, and configured to translate the query into the predetermined natural language; an extraction module configured to extract from the query formulated in the predetermined natural language at least one keyword representing the query; an identification module configured to identify, using the at least one keyword extracted, a target device supporting the predetermined natural language towards which to transmit the query; and a second transmitting/receiving module configured to transmit the query formulated in the natural language to the target device.

Communication devices and methods

A management method that allows a communication device to benefit from a network connectivity provided by a third party via the operator network. The method includes: receiving, from the communication device, a request for attachment to the operator network and an identifier of the third party; obtaining, using the identifier of the third party, contact information of a software control gateway instantiated for controlling access to a network slice allocated by the operator to the third party, this contact information including a reachability address of the software control gateway or an identifier of the network slice allocated to the third party and access to which is controlled by the software control gateway; and sending a message to the device containing the contact information and inviting the communication device to attach to the software control gateway using this contact information.

The present invention relates to a method for authorization management in a community () of connected objects (), a master object being determined in said community, the method comprising:

Method for authorization management in a community of connected objects

A method for controlling an action includes: receiving from a server an authorization request relating to at least one action for which a first user has execution rights, and for which a command has been formulated by a second user, the request containing data relating to the action and a delegation token certifying a delegation of the action by the first user to the second user; analyzing the request on the basis of the token; determining whether consent of the first user should be requested; sending to a terminal of the first user, a consent request and receiving a response; and sending to the server a response to the request relating to the action and signaling denial or consent.

Control of delegation rights

A management method for managing an identity of a first user during communication between a first web browser installed on a communication terminal of the first user and a second web browser installed on a communication terminal of a second user is disclosed. The method includes the first user obtaining at least one first data item characteristic of the second user. The method also includes associating an identity of the first user with the at least one first data item characteristic of the second user. The method also includes making the identity of the first user associated with the at least one first characteristic data item available to the second user on condition that the second user holds at least one second data item corresponding to the first data item characteristic of the second user.

The invention relates to a method of initializing a communications session between a plurality of terminals. According to the invention, the initialization method is adapted, as a function of capacity data for at least one terminal, to determine a set of at least one stream transmission channel to be set up between entities of a group of entities comprising said terminals, each channel being for setting up between a first entity and a second entity of the group either directly, or indirectly via at least one third entity of said group, and to transmit at least one entity identifier to at least one first entity of the group in order to set up at least one channel of the set. The invention also relates to a method of accessing a communications session, the method being adapted to receive at least one identifier of at least one entity with which at least one channel is to be set up and to set up at least one channel with at least one entity for which said at least one identifier has been received.
