Embodiment Construction

[0058] In order to avoid the problem of data loss caused by congestion when the network control device transmits data, an embodiment of the present invention provides a congestion control processing method. In this method, the network control device transfers the terminal's high-speed downlink shared channel ( HS-DSCH) transmission parameters are adjusted down, so that the bandwidth required for data transmission according to the adjusted HS-DSCH transmission parameters is not greater than the current idle bandwidth.

[0059] The network control equipment includes a base station controller (BSC), a radio network controller (RNC) and the like.

[0060] see figure 2 The congestion control processing method provided by the embodiment of the present invention specifically includes the following steps:

[0061] Step 20: The network control device obtains the transmission parameters of the high-speed downlink shared channel HS-DSCH of the terminal;

[0062] Step 21: The network c...

Abstract

The embodiment of the invention discloses a method for processing congestion control. The method comprises the following steps that: network control equipment acquires high-speed downlink shared channel (HS-DSCH) transmission parameters of a terminal; a bandwidth needed for transmitting data according to the HS-DSCH transmission parameters is confirmed; and when the confirmed bandwidth is greater than the current idle bandwidth of the network control equipment, the network control equipment adjusts the HS-DSCH transmission parameters according to the idle bandwidth and transmits the data according to the adjusted HS-DSCH transmission parameters. The embodiment of the invention also discloses radio network control equipment. Through the method and the equipment, data transmission congestion can be controlled effectively, so that the problem of data packet loss is solved and the stability of a user rate is improved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a processing method and equipment for congestion control. Background technique [0002] In the existing third-generation mobile communication system, the networking mode between the radio network control equipment (RNC) and the base station (Node B) is as follows: figure 1 shown. [0003] There are two modes of connection between RNC and Node B: asynchronous transfer mode (ATM) and IP mode, both of which can exist at the same time, or only one can exist. At the same time, there is not necessarily a direct physical connection between the RNC and the NodeB, and the RNC and the NodeB can be directly connected to the transmission network. [0004] RNC and Node B need to allocate a certain amount of bandwidth for service transmission. The 3G system can not only carry voice users, but also need to carry videophone services and interactive / background services. These diffe...
