HSUPA Iub Congestion Control

HSUPA Iub congestion control The HSUPA Congestion Control aims to balance the work load of the RNC introduced by  processing of the uplink traffic coming from the UEs. Congestion Congestion control for high speed uplink is a critical feature in the sense that the RNC might end up in a situation where it cannot handle all the traffic generated by b y all the users, although the users are given the maximum transmission speed. Congestion can occur on the transport path to the RNC or internally inside the RNC. In both cases, it is the responsibility of the RNC to take action to reduce the congestion. Whatever the source of congestion, the RNC must send indication to the originator of the excess traffic. For more information on the HSUPA Congestion Control and the usage of counters in  parameter optimisation, see Feature RAN992: HSUPA Congestion Congestion Control, Feature Description.

Counter ID: M1022C69

Network element name: DELAY BUILDUP INDICATIONS SENT DUE TO IUB DELAY

Version: 1.0

NetAct name: IUB_DELAY_CC_DELAY_IN IUB_DELAY_CC_DELAY_IND D

Description: The number of "Congestion Indication control frame - delay build-up" messages sent to the BTS due to an Iub delay detected by the Frame protocol.

Updated: When the RNC Frame Protocol entity sends a "Congestion Indication control frame - delay build-up" indication message to the base station and the indication was triggered by congestion detected by the Frame Protocol entity. This counter is updated for all cells in the UE's E-DCH active set controlled by the base station for which the Congestion Indication message was sent. The counter is not updated for E -DCH soft handover branches that are controlled by base stations whose Iub interfaces are not congested because the Congestion Indication message is not sent to them.
