Abstract: A method of communication between a first device and a second device is proposed, the first device being a low-power wireless end-device of an LP-WAN type data communication network, and the second device being a low-power wireless device that is not a node of the LP-WAN type data communication network, the first device being configured to behave as a relay node with respect to the second device. The method is implemented by the first device, and comprises: receiving a wake-up message from the second device, via an application layer of the first device; transmitting, to the second device, a message to acknowledge receipt of the wake-up message and to synchronize with the second device; receiving a data packet from the second device and transmitting the data packet on to the LP-WAN type data communication network, the data packet being inserted in an uplink data transmission message in a communication protocol of the LP-WAN type data communication network.

Abstract: The present invention relates to a method in a communication network for connecting at least one application server (AS) (213) of an internet protocol multimedia subsystem (IMS) (200) to an intelligent network (IN) (100) through an interface unit (301). The IMS (200) comprises a call server control function (CSCF) unit (205) connected to the at least one AS (213) arranged for processing call signaling. In the method the interface unit (301) directs the call signaling to the at least one AS (213) through the CSCF unit (205) and the at least one AS (213) processes the call signaling and sends the processed call signaling through the CSCF unit (205) back to the interface unit (301). Based on the information received in the call signaling processed by the at least one AS (213), the interface unit (301) then directs the call to a destination.

Abstract: The invention relates to a method of providing interactive services through a telecommunications network. In the method an audio/visual (A/V) stream and control data is exchanged between an application server and a multiplexing and access control module of the telecommunications network, by means of a multimedia bidirectional interactive protocol. Internet protocol television (IPTV) service protocols are implemented within the telecommunications network for communicating with customer premises television equipment, wherein the IPTV protocols include a streaming protocol for transmission to customer premises television equipment of an A/V stream received from the application server and a monodirectional interactive protocol for receiving user commands at the multiplexing and access control module.

Abstract: For transporting packets between an access interface of a subscriber installation and a concentrating router of a shared network the access interface carries out control operations on streams of packets transmitted to the concentrating router, within the framework of a contract between the subscriber and a manager of the shared network. After having carried out the control operations concerning a packet to be transmitted, the access interface transmits this packet to the concentrating router with a signature based on a secret shared with the concentrating router, authenticating that the packet has been subjected to the control operations.

The system has at least one customer server located at each one of a plurality of service suppliers, each customer server being connected to the wide area network also connected to a shared voice resources and/or video resources host server receiving particular service requests from customers also connected to the wide area network and initially responding to each received particular service request to determine the particular service supplier concerned as to the received particular service request, and to then direct each particular received service request to the at least one customer server located at the concerned particular service supplier for execution of particular service logic associated with the services provided by that service supplier.

Abstract: The packets of the sequence are stowed away in a packets memory organized as a stack, in association with respective processing labels. The processing label associated with each packet extracted from the packets memory is examined so as to activate a processing module selected as a function of the label received. The activated module performs an elementary processing of the packet extracted. The elementary processing performed by at least one of the processing modules comprises associating the extracted packet with a label modified in accordance with a labels translation table, the processed packet subsequently being stowed away again in the packets memory in association with the modified label.
