Patent number: 10103940Abstract: A method of updating at least two interconnected devices in a local network, a local network comprising at least two interconnected devices and a method of operating a remote management client and a device in this local network are provided. A resource location information of an update archive is communicated from a remote management client in the local network to the other devices in said network. The devices participating in the update communicate participation acknowledgement messages to the remote management client. The participating devices determine whether a next one of a predefined sequence of update statuses is reached. They notify the other participating devices that this update status has been reached and pause until all other participating devices have notified that they also have reached the same update status.Type: GrantFiled: June 4, 2014Date of Patent: October 16, 2018Assignee: Thomson LicensingInventors: Sylvain Dumet, Dirk Van De Poel

Patent number: 9749883Abstract: The application relates to a “wireless communication network including a station and an access point” which is in particular a Wi-Fi network according to the IEEE 802.11 standards. Internet service providers are searching for ways to get a better understanding of the end-user's wireless environment including link quality and performance. The proposed method calculates a performance value based on measured round trip times which are sent at different modulation rates. Based the change of performance in dependence of the modulation rate conclusions about the possible source of performance problems can be drawn, in particular it can be distinguished between (Bluetooth) interference and distance between station and access point being too large.Type: GrantFiled: February 13, 2012Date of Patent: August 29, 2017Assignee: Thomson LicensingInventors: Karel Van Doorselaer, Koen Van Oost, Sylvain Dumet, Dirk Van De Poel

Patent number: 9743298Abstract: The method for testing a wireless communications network including a station and an access point comprises the steps of sending broadcast packets from the station to the access point in a lower frequency band and waiting for confirmation, calculating a packet loss in the lower frequency band based on the number of sent and confirmed broadcast packets, and calculating a packet loss for a higher frequency band by taking into account the calculated packet loss of the lower frequency band and by using a correlation function between the lower frequency and the higher frequency band. The wireless communications network is in particular a communications network according to one of the IEEE 802.11 recommendations and the broadcast packets are in particular address resolution protocol packets.Type: GrantFiled: March 14, 2013Date of Patent: August 22, 2017Assignee: Thomson LicensingInventors: Karel Van Doorselaer, Koen Van Oost, Sylvain Dumet

Publication number: 20160142247Abstract: A method of updating at least two interconnected devices in a local network, a local network comprising at least two interconnected devices and a method of operating a remote management client and a device in this local network are provided. A resource location information of an update archive is communicated from a remote management client in the local network to the other devices in said network. The devices participating in the update communicate participation acknowledgement messages to the remote management client. The participating devices determine whether a next one of a pre-defined sequence of update statuses is reached. They notify the other participating devices that this update status has been reached and pause until all other participating devices have notified that they also have reached the same update status.Type: ApplicationFiled: June 4, 2014Publication date: May 19, 2016Inventors: Sylvain DUMET, Dirk VAN DE POEL

Patent number: 8320370Abstract: The present invention is related to a method for routing data packets in a routing device connecting a first network and a second network, and to a corresponding routing device. The method comprises the steps of receiving a frame from a device connected to the first network; forwarding the frame to an internal bridge module of the device; checking whether the frame contains a multicast group management message and in the affirmative, creating a new frame comprising as destination address the destination address of an internal multicast group management module and as payload at least the multicast management data of the received frame; and forwarding this new frame to the internal bridge function.Type: GrantFiled: September 24, 2003Date of Patent: November 27, 2012Assignee: Thomson LicensingInventors: Sylvain Dumet, Jan Voet

Patent number: 7804838Abstract: The present invention concerns a time synchronizing device and process, and a local gateway comprising that device. The time synchronizing device synchronizes a router arranged between two communication networks. It comprises intercepting means of a message coming from an apparatus of a source network for that message, having a specific time clock, and directed to a target network for that message, preparing means of a time request able to be executed in that apparatus so as to cause synchronizing data based on that specific clock to be obtained from that apparatus and to be transmitted back to the synchronizing device, sending means of the time request to the apparatus, forwarding means of the intercepted message to the target network after the preparing means have prepared the time request, receiving means of the synchronizing data, and exploiting means of those data to synchronize a local time clock used by the router with respect to that specific time clock .Application to home networks.Type: GrantFiled: January 3, 2005Date of Patent: September 28, 2010Assignee: Thomson LicensingInventors: Sylvain Dumet, Dirk Van De Poel
