Abstract: A method of multicast transmission in a communication network by using IGMP protocol, to a plurality of IGMP-equipped hosts serving end customers of the network, the method comprises:—using IGMP protocol to request receipt of information along a multicast channel, by a particular end customer;—adding the end customer to a multicast group including, upon adding said particular end customer, at least one of the end customers;—delivering information along the multicast channel to the end customers belonging to the multicast group, and in response to the request, ensuring for the particular end customer access to information delivered along the multicast channel by transmitting to that end customer access data, which includes: churning information indicative of a multicast churning key and/or service information, and/or a combination thereof.

Abstract: A method is provided to enable providing broadband communication services to a subscriber having a number of devices connected to a regional gateway (e.g. CPE). The method comprises the steps of: carrying out an authentication process between at one of the subscriber's devices and a network server, upon authenticating the subscriber, downloading information associated with that subscriber to an access node. At the access node, designating a port for communications with the regional gateway, and based on identification of the subscriber, allowing the provisioning of broadband communication services to all of the subscriber's devices connected to regional gateway. When the subscriber's device used for the authentication process is disconnected, the system shall continue allowing the provisioning of the already allowed broadband communication services to the remaining devices that are still connected to the regional gateway.

Abstract: Method of control of a three-phase or multi-three-phase invertor (1) supplied from a DC voltage source (2) and controlled by a processor (5) for deriving, in the course of successive slaving periods, signals for pulse-width-modulation control of the transistors of the invertor. It consists, from measuring the power supply current of the invertor and from taking account of the switching states of the transistors, in reconstituting the phase currents.
