A method for providing access by secondary stations (12, 14, 16) to a shared transmission medium, maintains a list of secondary stations (12, 14, 16). A poll is transmitted by a primary station (10) to one of the secondary stations (12, 14, 16). The secondary station (12, 14, 16) waits for a poll, examines the transmission allocation, determines if there is congestion and transmits, along with the data in response to the poll, information regarding congestion. A system for providing such access includes a primary station (10) and a plurality of secondary stations (12, 14, 16). The primary station includes a polling controller (30), a receiver (32), a transmitter (34), a summer (36), a secondary station poll list database (38) and a data traffic controller (40).
Un procédé permettant à des stations secondaires (12, 14, 16) d'accéder à un support de transmission partagé détient une liste de stations secondaires (12, 14, 16). Un appel est transmis par une station primaire (10) à l'une des stations secondaires (12, 14, 16). La station secondaire (12, 14, 16) attend un appel, examine l'affectation de la transmission, détermine s'il y a encombrement et transmet, avec les données en réponse à l'appel, des informations concernant l'encombrement. Un système permettant de réaliser cet accès comprend une station primaire (10) et une pluralité de stations secondaires (12, 14, 16). La station primaire comprend un contrôleur d'appel (30), un récepteur (32), un émetteur (34), un additionneur (36), une base de données (38) de listes d'appels de stations secondaires et un contrôleur (40) de trafic de données.
