Method, system and apparatus for adjusting data package transmission velocity

Abstract

An embodiment of the invention discloses a method for regulating the transmitting speed of data package, a system and a device thereof. The method for regulating the transmitting speed of the data package comprises the following steps: calculating the shaking statistic of the data in the transmission link according to the received backward reporting BR package; determining whether the shaking statistic exceeds the prearranged first speed reduction threshold; and if the shaking statistic exceeds the first speed reduction threshold, executing speed reduction procession to the transmission speed of the data package. Through the embodiment of the invention, the base station controller self-adaptively regulates the data package transmission speed of the base station controller according to the shaking statistic calculated by the base station controller thereby effectively controlling the discharging flow rate of the base station controller, increasing the stability of the system under the state of heavy load, reducing the package loss and time delay of the transmission link and increasing the usage factor of the band width.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a method, system and device for adjusting a data packet sending rate. Background technique [0002] In the field of communication, the transmission link between the base station and the base station controller often needs to occupy a large cost of the operator, so many operators use a shared method to connect the transmission link between the base station and the base station controller to save costs. The problem brought about by this is that the transmission rate of the transmission link is unstable, and the bandwidth fluctuates greatly. It is necessary for 3G (3rd Generation, third-generation mobile communication technology) equipment to automatically detect the rate fluctuation and available bandwidth of the transmission link, and then to The transmission link bandwidth is controlled to ensure the maximum utilization of the transmission lin...

Problems solved by technology

[0004] In the closed-loop control system, when the frequency of the input signal is higher than a certain threshold, that is, when the change speed of the transmission link bandwidth is higher than a certain threshold, due to the limitation of the system hardware performance, for example: the sending of FM (Forward Monitoring, forward monitoring) packets The period cannot be infinitely small, which will cause the closed-loop control system to be unable to track the change of the input signal, so that it cannot accurately detect the change of the bandwidth of the transmission link

[0005] Therefore, the inventors have found that at least the following problems exist in the prior art: for the closed-loop control system, the transmission link bandwidth cannot be adjusted correctly in the prior art when the bandwidth of the transmission link changes. When the transmission link bandwidth estimated by the closed-loop control system is greater than the actual value , will cause a large amount of packet loss on the transmission link, and when the transmission link bandwidth estimated by the closed-loop control system is smaller than the actual value, it will cause the transmission link bandwidth utilization to decrease
