Embodiment Construction
[0032] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
[0033] refer to figure 2 , the flow control method between the base station and the radio network controller according to the present invention comprises the following steps:
[0034] Step S102, the base station performs congestion detection, and sends a congestion indication control frame to the radio network controller according to the congestion state, and the congestion indication control frame includes a congestion indication frame and a congestion relief indication frame.
[0035] If the base station detects congestion, it sends one or more congestion indication frames, corresponding to one or more congestion levels.
[0036] If the base station detects that the congestion has returned to normal, it sends a congestion relief indication frame every interval of network delay.
[0037] Step S104, the radio network controller judges the type of the received...

The invention discloses a control method over the flow between a base station and a radio network controller. The base station carries out the congestion detection and sends a congestion indication control frame to the radio network controller according to the congestion state. The congestion indication control frame comprises a congestion indication frame and a congestion rescission indication frame. The radio network controller judges the type of the received congestion indication control frame. If the congestion indication frame is received, the radio network controller regulates the data flux according to the received congestion indication frame and the related previous records of the congestion indication; if the congestion rescission indication frame is received, the radio network controller will recover data flux according to the received congestion rescission indication frame and the related previous records of the congestion indication. Under the circumstance that the networktransmission between NodeB and RNC is restricted, the invention effectively prevents the solid network transmission congestion by adding the network resource restriction between NodeB and RNC to the acceptance judgment. Thus the service quality is improved.
Description
technical field [0001] The invention relates to a wideband code division multiple access system in the field of wireless communication, in particular to a flow control method between a base station and a wireless network controller. Background technique [0002] Between NodeB (base station) and RNC (Radio Network Controller, radio network controller) network nodes, the transmission bandwidth is limited. From the perspective of operating costs, operators usually determine the transmission according to the traffic model of the network coverage area bandwidth. Therefore, when the RNC sends data to the NodeB, it needs to reasonably allocate resources among various services according to a certain algorithm or strategy according to the configuration of this part of the bandwidth. [0003] However, between multiple NodeBs and a single RNC, in order to use the total network transmission resources reasonably, it is necessary to configure a network convergence node to allocate the to...
