Embodiment Construction

[0057] The present invention provides a method for uplink load control. The core of the present invention is: on the one hand, improve RTWP The measured noise improves the accuracy of NR and reduces load estimation deviation; on the other hand, combined with the auxiliary uplink load control method based on user QoS demodulation performance, the system load is adaptively controlled according to the current actual load status.

[0058] Describe the present invention in detail below in conjunction with accompanying drawing, the present invention at first provides a kind of background noise P N The improved measurement method, the specific processing flow of the method is as follows figure 2 shown.

[0059] Step 2-1. Sampling background noise P K times every morning Nj , and choose P Nj The minimum value in .

[0060] Since there is little or no traffic on the network in the early hours of every day, the network is close to no-load status at this time. Therefore, according ...

Abstract

The provided method comprises: measuring the background noise of subzone for real noise power to obtain the current upper loading value; according to relation between current and set load value, controlling the upper loading. This invention can improve system performance well.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for controlling uplink load. Background technique [0002] GSM (Global System for Mobile Communications), as the second-generation digital mobile cellular communication system, has been widely used all over the world. Due to the shortage of frequency resources and the demand for more new services, 3G (third-generation mobile communication system) is an inevitable trend. WCDMA (Wideband Code Division Multiple Access), one of the three major 3G standard technologies, is currently the most widely used in 3G standards. The WCDMA system combines high-speed mobile access with services based on Internet Protocol, and provides users with richer wireless communication services while improving the efficiency of wireless frequency utilization. [0003] The coverage area of ​​the WCDMA system is not determined by the absolute value of the signal level like GSM, and its covera...
