  • Patent number: 9049053
    Abstract: The present invention relates to a method of managing an object (OBJ) through a management gateway (ONG) communicating with a system architecture present on a telecommunications network offering functionalities for registering objects and for routing messages. The method includes the registering (201) of the object with the system architecture by way of the management gateway, by using the registration functionality, and the control (203) of a parameter associated with the object through the management gateway, using the message routing functionality. The present invention also relates to a management gateway (ONG) corresponding to the management method.

  • Patent number: 8233485
    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.

  • Publication number: 20090055878
    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.

  • Patent number: 7409541
    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.

  • Patent number: 6925507
    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.
