Title (EN) PACKET SWITCHED RADIO CHANNEL CONGESTION CONTROL
(FR) CONTROLE DE L'ENCOMBREMENT SUR UN CANAL RADIO A COMMUTATION PAR PAQUETS
Abstract:
(EN) A method and system for controlling congestion on a packet switched radio channel (PRCH) (128, 130, 132) is disclosed. A PRCH congestion control function (418a, 418b, 418c, 418d) determines if the average time delay for packet calls on the PRCH (128, 130, 132) is within a delay alarm level. If the average time delay is not within the delay alarm level, it is then determined which packet calls to expel from the PRCH (128, 130, 132) in order to decrease the average time delay. The determination of congestion may be made for each of the uplink and downlink of a PRCH (128, 130, 132) seaprately, or, on the combined uplink and downlink of the PRCH (128, 130, 132).
(FR) La présente invention concerne un procédé et un système de contrôle de l'encombrement sur un canal radio à commutation par paquets (CRCP) (128, 130, 132). Une fonction de contrôle de l'encombrement sur CRCP (418a, 418b, 418c, 418d) détermine si le retard moyen pour les communications par paquets sur le CRCP (128, 130, 132) se situe à un niveau d'alarme pour retard. Si ce n'est pas le cas, on détermine quelles sont les communications par paquets qu'il faut rejeter du CRCP (128, 130, 132) afin de réduire le retard moyen. La détermination de l'encombrement peut être faite séparément pour chacune des liaisons montante et descendante d'un CRCP (128, 130, 132) ou bien pour les deux combinées.
