Abstract
(EN) [Problem] A communication control device is provided. The communication control device can reduce a recalculation load of interference control that may occur due to a change in an operation state of a wireless system within a time interval between periodical exchanges of information between databases in secondary use by the wireless system.[Solutio] A communication control device is provided. The communication control device includes a controller that sets an acceptable interference amount of a primary system that is acceptable by a secondary system that secondarily uses a radio wave in a predetermined frequency band allocated to the primary system. In the setting of the acceptable interference amount, the controller sets a first margin to be allocated to the secondary system that is operating, a second margin that absorbs a change in the first margin that has been caused by a change in the total number of secondary systems, and a third margin to be commonly set between the communication control device and another communication control device.
(FR) [Problème] Fournir un dispositif de commande de communication avec lequel il est possible de réduire la charge de recalcul de commande d'interférences qui pourrait se produire en raison d'un changement d'état de fonctionnement d'un système sans fil dans l'intervalle d'échange d'informations entre des bases de données qui est effectué périodiquement pendant l'utilisation secondaire du système sans fil. À cet effet, l'invention concerne un dispositif de commande de communication qui est pourvu d'une unité de commande pour définir une quantité admissible d'interférences provenant d'un système primaire qui est tolérable pour des systèmes secondaires utilisant accessoirement des ondes radio d'une bande de fréquence prescrite attribuée au système primaire. Lors de la définition de la quantité admissible d'interférences, l'unité de commande définit une première marge qui est attribuée aux systèmes secondaires en fonctionnement, une seconde marge qui absorbe les changements de la première marge en raison d'un changement du nombre total de systèmes secondaires, et une troisième marge qui est définie en commun avec d'autres dispositifs de commande de communication.
