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 informati

Embodiment Construction

[0026] The technical solutions and advantages of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] In order to improve the uplink bandwidth utilization of the transmission link between the base station controller and the base station, such as figure 1 As shown, Embodiment 1 of the present invention provides a data transmission control system, including: a base station controller 12 and at least one base station 11, wherein the base station 11 is connected to the base station controller 12 in a communicable manner.

[0028] Wherein, the base station 11 is configured to send the high-speed uplink packet access service data to the base station controller 12, and acquire the remaining buffer time of the high-speed uplink packet access service queue. When the remaining buffer time is less than the congestion time threshold, reduce the traffic of the high-speed uplink packet access service; when the rem...

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...
