Method for the dynamic allocation of radio channels (Ci) in digital telecommunication networks with time division duplex access, whose radio signals are divided into frames having pre-determined duration and each frame is subdivided into a pre-determined number of time intervals (Ti) which are assigned priority values (Pi) based on measures of channel interference and/or quality (Ci), each communication service (Sx) employing a particular number (Rx) of said channels (Ci) at a time. This method includes at least a measurement of the signal attenuation (PLx) with which said communication service (Sx) has been requested, as well as the allocation of said number (Rx) of channels (Ci) of the communication service (Sx) in a time interval (Tx) having an increasing priority value (Pi) with the attenuation (PLx) of the relevant signal, in order that the services employing said number (Rx) of channels (Ci) are allocated in time intervals (Ti) having increasing priority values (Pi) with the attenuation of the relevant signal.

L'invention concerne un procédé d'attribution dynamique de bandes d'ondes (Ci) dans des réseaux de télécommunication numérique à accès duplex à répartition dans le temps, dont les signaux radioélectriques sont divisés en trames ayant des durées déterminées, et chaque trame étant subdivisée en un nombre déterminé d'intervalles de temps (Ti) qui sont assignées valeurs de priorité (Pi) en fonction des mesures d'interférence et/ou de qualité de canal (Ci), chaque service de communication (Sx) utilisant un nombre particulier (Rx) de canaux (Ci) en une fois. Ce procédé comprend au moins une mesure d'atténuation de signal (PLx) avec laquelle le service de communication (Sx) a été demandé, ainsi que l'allocation du nombre (Rx) de canaux (Ci) du service de communication (Sx) dans un intervalle de temps (Tx) ayant une valeur de priorité augmentée (Pi) avec l'atténuation (PLx) du signal important, de manière que les services utilisant ce nombre (Rx) de canaux (Ci) soient alloués dans des intervalles de temps (Ti) ayant des valeurs de priorité améliorées (Pi) avec l'atténuation du signal important.
