The invention relates to a method for managing charging currents delivered by an installation () for charging electric vehicle batteries in a parking lot (P), comprising a set of electric charging terminals (B, . . . B) connected to an electric power distribution network (), each terminal being able to deliver a charging current value to an electric vehicle (VE, . . . VE) connected thereto. The method comprises: determining a maximum permissible value of the current at a connection point () for connecting the installation () to the network (); storing, in a central management system () linked to the terminals, on the one hand, the electric charging terminals of a first subset of said set corresponding to the occupied terminals and, on the other hand, the electric charging terminals of a second subset corresponding to the available terminals; measuring the sum of the charging currents delivered by the terminals of the first subset; computing, by the system (), an available current value according to a difference between the maximum permissible value and the sum of the delivered charging currents; and, for each new electric vehicle entering the parking lot (P) for charging purposes: computing, by the system (), a deviation between the computed available current value and a charging current value able to be delivered by a determined terminal of the second subset; if the deviation is negative, transmitting, to one or more terminals selected from the first set, an order to reduce the charging current value delivered by each terminal to the vehicle connected thereto, so as to cover the deviation in absolute value; and transmitting, to the determined terminal of the second subset, an authorization message for charging the new vehicle at a predetermined charging current value.

Managing an installation for charging electric motor vehicle batteries in a parking lot

When establishing an emergency connection in a wireless network having an authentication server, wherein a user terminal is a non-subscriber to the network, a dialed number is recognized as an emergency number and the terminal sends a start-up message to a radio access point of the network. The terminal receives a first message that requests the identity of the terminal, from the access point in response to the start-up message, and sends a second message, which contains the identity of the terminal and an indication indicating that the terminal is attempting to make an emergency call. An authentication server determines that the second message contains an indication that the call is an emergency call, and sends an acceptance message to the terminal via the access point wherein a port of the access point is validated to permit the terminal to establish an emergency connection.

This method is used to send data representative of the location of communication terminals (T) to a call center (ECC) without using information processing means in the terminals and to send via heterogeneous communication networks (RP, RPT). This method consists, in the event of requesting the setting up of a telephone call between a terminal (T) and the call center (ECC) by means of a dedicated calling number, in sending the call center a signaling message for setting up the connection and comprising a selected call identifier and a text type message including data representative of the location of the calling terminal (T) and the selected call identifier. At the call center, the method consists in associating the signaling message received by the call center with the location data contained in the text message received by the call center if the signaling message and the text message include the same call identifier.

A power supply distributor permits to broadcast data received in phantom mode at one of its port to at least few of the other ports such that the respective apparatus connected to the power supply distributor will receive them. The power supply distributor includes modems for at least few of the communications links, while the modems are connected between each other through a multiplexer. Optionally, the multiplexer is setup with a switching function. This enables advantageously to select the ports to which received data in phantom mode will be forwarded allowing to buildup a communications link between different apparatus, such link being based solely on transmission of data in phantom mode. Such links can be setup in a bi-directional modus between at least two apparatus. A ghost network is designed which is mapped on an existing network and based on transmission of data in a phantom mode.

An Ethernet card (CL) is dedicated to the connection of a communication terminal (UE) to a local network via an Ethernet connection (CX). The terminal (UE) can be powered electrically by first power means (MAP), and includes a first internal bus (PCI). The card (CL) includes i) second power means (MAA) capable of being powered remotely, via the Ethernet connection (CX), by power control means (PPP) on the local network, ii) a second bus (PCI) coupled to the first internal bus (PCI), iii) coupling means (MCP) coupled to the second bus (PCI), and iv) control means (MCC) connected logically to the first (MAP) and second (MAA) power means and tasked, in the event of detection of remote powering of the card (CL) and the absence of electrical powering of the terminal (UE) by its first power means (MAP), to command the coupling means to electrically decouple the card from the first internal bus (PCI), in order to allow its operation independently of the terminal (UE).

Before any supply of remote power to a telecommunications terminal connected to a local area network, the Ethernet equipment must recognize the power class of the terminal by measuring a specific electrical signature of the terminal via their interconnection. If the Ethernet equipment is unable to supply the required power, then it will send a specific signal via the interconnection which will activate an alarm on the terminal. The possibility to be alerted by a specific alarm from the terminal if no remote power can be supplied to it, will advantageously inform the terminal user of the problem and allow the user to look for an alternative.
