摘要
Method for reducing the congestion in internal interfaces in UTRAN networks according to user prioritization, comprising:detecting a congestion situation in the internal interface and when said congestion situation has been detected, reducing the bit rate of users according to their priority, said priority being established according to the values of the Allocation Retention Priority, ARP, and the Traffic Handling Priority, THP, parameters stored in the HLR for each user. The method may further include detecting an absence of said congestion situation and when said absence of congestion situation has been detected, increasing the bit rate of users according to their priority, said priority being established according to the values of their ARP and THP parameters. The congestion situation can be detected whenever the lub occupancy exceeds a congestion control activation threshold (CCAT), whereas the absence of congestion whenever the lub occupancy goes below a congestion control deactivation threshold (CCDT).
