  • Channel allocation methods in a communication network and corresponding system
    Patent number: 6370117
    Abstract: The invention relates to a resource allocation method and system making use of a dynamically controlled boundary policy to satisfy the quality of service parameters guaranteed by the system for two traffic classes (a constant bit rate traffic, and a bursty data one also called VBR traffic) having to share a communication channel divided into frames. The boundary position (BP) between the traffic sub-frames and hence the allocation decision itself are defined by a resource allocator (23) for each frame, after monitoring the filling level of traffic request queues (21, 22).

  • Transmission control method between a plurality of stations
    Patent number: 6151329
    Abstract: A communication protocol for use by stations in multiple access telecommunication network wherein communication between stations is via a master station. An upstream channel to the master station is shared by the other stations and has successive frames each consisting of K message slots, each message slot including a data part (DM) for the transmission of a message and M minislots for transmission of slot reservation signals. According to the invention, in case of unsuccessful message transmission and collision between transmission requests, reservation signals for retransmission of a message can be transmitted in any of the K.times.M minislots of each entire frame. The large number of minislots thereby made available reduces the danger of collision between retransmission requests.

  • Transmission control method between a plurality of stations and corresponding communication stations
    Patent number: 5953321
    Abstract: A communication protocol is disclosed where unsuccessful transmissions between stations are reduced. Each station includes a first queue for receiving newly generated messages and a second queue for receiving recycled messages which were not successfully transmitted. A detector in a reception sub-assembly of each station detects that the number of unsuccessful transmissions or collisions exceeds a predetermined threshold. Until the collisions are solved, a recycling circuit recycles the collided messages by providing them to the second queue and increasing their transmission priority over any newly generated messages contained in the first queue.
