Data transmission controlling method, apparatus and system

Abstract

An embodiment of the invention discloses a data transmission control method, a device and a system thereof. The invention relates to the technical field of communication and is invented for increasing the usage factor of uplink bandwidth of transmission link between the base station controller and the base station. The method comprises the following steps: obtaining the residual cache time of high speed uplink chain grouping access service queue; when the residual cache time is smaller than the congestion time threshold, reducing the flow of high speed uplink grouping access service; and when the residual cache time is larger than the congestion time threshold, increasing the flow of high speed uplink grouping access service. The embodiment of the invention is mainly applied for the uplink flow control technique of base station.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission control method, device and system. Background technique [0002] With the development of FMC (Fixed Mobile Convergence, fixed and mobile convergence) technology, it has become a trend to use IP technology to carry 3G services. In the prior art, a base station controller, such as an RNC (RadioNetwork Controller, radio network controller) is connected to a transmission network through a GE (Gigabit Ethernet) or FE (Fast Ethernet) link, while a Node B (base station) is It may be connected to the transport network through FE links, E1 links or STM-1 (Synchronous Transport-1, synchronous transport module 1) links, or may be connected to the transport network through N pieces of E1. Among the signal transmission directions between the base station controller and the base station, the direction from the base station controller to the base station is c...

Problems solved by technology

[0008] For method 1, if the sum of the transmission bandwidth configured on the three logical ports is equal to the physical bandwidth of the port, then when the voice service is relatively idle, the remaining bandwidth of the voice service cannot be used by the HSUPA service, so the physical Multiplexing of port bandwidth between different services, low bandwidth utilization

For method 2, if the base station controller feeds back frame loss information to instruct the base station to reduce the transmission traffic of HSUPA, the base station controller feeds back the frame loss information until the base station receives the feedback frame loss information, and then the base station starts to reduce HSUPA For business traffic, there will be frame loss during the whole process.

And if these frames are to be retransmitted, it will cause a waste of bandwidth and make the utilization of bandwidth low.
