Problems solved by technology

[0012] The removal of the user directly causes call drop, which affects the experience of the user; moreover, because the system does not control the new call, if the new call is still a call initiated by a user in a bad wireless environment, the new call will be removed immediately. resulting in poor user satisfaction

Embodiment Construction

[0076] In the cdma2000 1x system, for the basic channel, there are four channel rate types, namely rate1, rate1 / 2, rate1 / 4 and rate1 / 8. The channel spreading gain of the basic channel is inversely proportional to the channel rate, that is, the lower the channel rate, the higher the spreading gain, so that the power required to achieve the same frame error rate is also lower.

[0077] In a common channel model, the power required for a channel rate of rate1 / 2 is 1 / 2 that of rate1, and the power required for a channel rate of rate1 / 4 and rate1 / 8 is 1 / 4 and 1 / 8 of rate1, respectively.

[0078] Currently, there are three commonly used speech service codes EVRC (Enhanced Variable Rate Codec, enhanced variable rate speech codec), 8K QCELP (Qualcomm Code Excited LinearPrediction 8K, Qualcomm Code Excited Linear Prediction 8K speech codec) and 13K QCELP ( Qualcomm Code Excited Linear Prediction 13K, Qualcomm Code Excited Linear Prediction 13K speech codec) has 5 kinds of rate reductio...

Abstract

The invention is concerned with the system load controlling method and the controlling equipment, it is: reduces lower speed mode of the conversation downward / upward speech coding auto-adapted when the load of the system is overweight such as front load or reverse load overweight, ensures the conversation sound quality, reduces the drop-line rate of the user, saves the front power and increasesthe capacity of the system; the invention increases the capacity of the system, and reduces lower speed mode of the conversation downward / upward speech coding auto-adapted when the load of the system is light such as front load or reverse load light, reduces the percent of call loss and the drop-line rate, improves the conversation quality of the user; improves the capacity of the system, provides better benefit for the operator.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and device for controlling system load. Background technique [0002] In the cdma2000 1x system, there are many factors that affect the forward capacity, such as CE, Walsh code, power, and transmission bandwidth. In general, the forward transmission power of the system is the bottleneck, and the rational and effective use of the forward transmission power plays a key role in improving the capacity of the cdma2000 1x system. [0003] At present, there are mainly two methods for rationally and effectively utilizing the forward transmit power. [0004] Method 1: Adjust the technical solution of FER (Frame Error Rate, Frame Error Rate). [0005] In order to use the forward transmission power reasonably and effectively, this method makes full use of the characteristics of the soft capacity of the cdma2000 system. The power required by each channel, thereby re...
