Abstract:
The invention relates to a method of communicating between at least two devices, comprising in particular the following steps: a step of hooking up a first device and at least one second device, and a step of transferring a first multimedia stream from the first device to the second device, characterized in that it also comprises the following steps: a step of determining, in the course of which it is noted that the first device or a first communication network to which the first device is connected or a second network to which the second device is connected is adapted for the production or transfer of a multimedia stream comprising N channels, and that the second device comprises means for processing a multimedia stream comprising P channels, and a step of trunking a second multimedia stream to the second device, carried out in parallel with the step of transferring the first multimedia stream. The invention also relates to an associated communication system. Application to telephony or videophony over IP.
Abstract:
A method is provided for updating a data-rendering device connected to a communications network by an intermediate device. A specific electronic address is assigned to the data-rendering device. The method includes associating at least one identifier, preliminarily assigned to the intermediate device, with the electronic address. The at least one identifier belongs to the group including at least: one dynamic connection identifier of the intermediate device and one user account identifier (AID).
Abstract:
A method that may be implemented in a CSCF entity to acknowledge a REGISTER type request sent by a terminal. It comprises: a step (E30) of estimating, for at least one future time window, the number of REGISTER requests that are liable to be received by the CSCF entity during said future time window; a step of selecting a future time window; and a step (E110) of sending to the sending terminal an acknowledgment message (200, 503) including a period (EXPIRES) selected so that the next REGISTER request sent by that terminal will be sent during said selected future window.
Abstract:
A data exchange system on a data transfer network (2) between a receiver station (6) and a data (I*) server (4) with conditional access, wherein data exchanges over the network (2) are managed and authorized by a control server (20). The control server (20) is associated with: automatic elements (7, 22, 24) forming a catalogue of useable access instruments, accessible to a user of the receiver station (6) for selection, by the user, of one of the access instruments; automatic elements (26) for determining corresponding control parameters of data exchange control over the network (2); and automatic elements (28) for controlling data exchanges over the network (2) based on the thus determined parameters.

Abstract:
A method of transmitting an indication inhibiting at least one service associated with a called device, the method including a step for generating a call signal (4001) in order to set up a communication between a calling device and the called device via at least one communication network. Such a method also comprises a substitution step (4005), to be executed when said call signal comprises an inhibiting command, and during which said inhibiting command is replaced by said inhibiting indication.
Abstract:
An SIP message processing method is disclosed. It may be performed by a node of a telecommunications network having a home gateway connected to an IMS network core via an access connection, at least a first SIP terminal and a second SIP terminal locally connected to said home gateway. It may include obtaining a bandwidth of the access connection, receiving a first SIP message concerning the first SIP session, determining the bandwidth in use by the first SIP session as a function of the first SIP message, receiving a second SIP message concerning the second SIP session, determining a bandwidth authorized for the second SIP session as a function of the second SIP message, of the bandwidth of the access connection, and of the bandwidth in use by the first SIP session, and sending a third SIP message to the first terminal, the second terminal, or the IMS network core.
Abstract:
A method and apparatus are provided for processing a request to instigate communication, received by a routing device associated with a plurality of terminals. The request relates to a communication to be established between a sender device of the request and at least one of the terminals. The method includes a step of comparing communication capabilities of said sender device with respective communication capabilities of one or more terminals, called addressee terminals, which are able to establish said communication, so as to identify at least one terminal having capabilities making it possible to establish with the sender device a communication of maximum quality. A call notification is transmitted to at least one of the addressee terminals, which is suitable for triggering on the addressee terminal a call presentation prompting a user to use, by priority, one of the terminals identified during the comparison step to establish the communication.
Abstract:
A method of transferring an audio stream between at least two terminals, comprising the following steps: a step of connecting a first device and at least a second device; and a step of transferring an audio stream from the first device to the second device; the method being characterized in that it further comprises the following steps: a determination step during which it is determined that the first device or a first network to which the first device is connected or a second network to which the second device is connected is adapted to produce or transfer an audio stream comprising N channels and that the second device includes an electroacoustic transducer adapted to receive an audio stream comprising P channels; and a conversion step during which an audio stream sent by the first device or transmitted by the first network or transmitted by the second network is converted into an audio stream comprising P channels. An associated transfer system is also disclosed. Application to telephone or videophone communication in IP networks.
Abstract:
A method and apparatus are provided for management of registrations in an IMS network. The method includes: creating, for a given public identity, at least two registration queues, each one being associated with a registration policy; receiving a registration message sent by a terminal having the public identity; and assigning one of the registration queues to the terminal on the basis of a field included in the message.
