Load control method in high speed uplink packet access cell

Abstract

The present invention discloses a method of a high-speed uplink grouping access primary area load controlling, to solve the problem that the load in the HSUPA primary area can not be reasonably and flexibly decreased according to the attribute of the service. The method of a high-speed uplink grouping access primary area load controlling is that for a time delayed insensitiveness type service, a mixed automatic rushing transmission request power shifting of the service is adjusted low or a maximum retransmission time of the service is adjusted up, and the load of the service is decreased; the speed of a time delayed sensitiveness type service is directly reduced to ensure a bit rate, and the load of the service is decreased under a precondition that a lowest acceptable service quality of the user is ensured. The present invention combines the consideration of the transmission delay and the adjustment of the maximum retransmission time, to be used in the high-speed uplink grouping access primary area load controlling, to reasonably decrease the load in the HSUPA primary area according to the attribute of the service.

Description

technical field [0001] The present invention relates to a load control method of a mobile communication system, in particular to a load control method in a High Speed ​​Uplink Packet Access (HSUPA: High Speed ​​Uplink Packet Access) cell. Background technique [0002] High-speed uplink packet access is a third-generation mobile communication partnership project (3GPP: 3 rd Generation Project Partnership) is a new technology proposed in the sixth version (R6: Release 6) protocol in order to improve the throughput of uplink packet data. It greatly improves the system capacity and meets the high-speed uplink service requirements of users. [0003] The load of the high-speed uplink packet access cell is usually measured by the received total wideband power (RTWP: Received Total Wideband Power) value of the public measurement report. The HSUPA system will be overloaded during operation. The overload here means that the uplink or downlink load of the cell exceeds the overload th...

Problems solved by technology

[0005] At present, the WCDMA system often uses the method of reducing the service speed in the cell to reduce the load; because the load control of HSUPA is mainly done through the fast scheduling of NODE B, the traditional speed reduction strategy adopted by the RNC may not be effective: because the rate monitored by the RNC is only The average rate for a period of time, and the actual rate is constantly changing due to fast scheduling, that is to say, when the RNC load control initiates a process of reducing a certain rate to another rate, it may be due to the scheduling of NODE B that the rate may have May be higher, or have actually been lowered

And such a method cannot reasonably and flexibly reduce the load in the HSUPA cell according to the attributes of the business
