Problems solved by technology

Then, when the retransmitted UE successfully sends the data packet to the NodeB, it may cause an imbalance between the air interface traffic and the IUB interface traffic, and even cause buffer overflow, resulting in packet loss
[0005] It can be seen that the prior art cannot maintain a balance between air interface traffic and IUB interface traffic

Embodiment Construction

[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] The basic idea of ​​the present invention is: determine the pre-allocated IUB traffic increment according to the traffic scheduling algorithm, then compare the available IUB traffic increment obtained according to the gradient factor with the pre-allocated IUB traffic increment, and determine the IUB traffic allocated to the UE therefrom increment.

[0034] Fig. 1 shows a flow chart of the method for realizing uplink traffic control in the present invention. As shown in Figure 1, the method for realizing uplink flow control of the present invention comprises the following steps:

[0035] Step 101: the NodeB obtains the pre-allocated IUB traffic increment according to the traffic scheduling algorithm, and obtains the air interface ...

Abstract

The invention provides a of ascending flow control method, the key lies in that the establishment of a gradual factor, take the product of IUB residual flow of base stations nodes (NodeB) and gradual factor as a control to distribute IUB flow incremental value to user equipment (UE). NodeB first obtain the predistribute IUB flow incremental value according to the flow scheduling algorithm, and calculate the empty flux according to size information of data packet the UE uploaded; NodeB obtains the IUB flow incremental value distribute to UE according to empty flow, gradual factor and predistribute IUB flow incremental value, finally notice to UE the distributed IUB incremental flow value. Use the scheme of this invention can gradually release the remaining IUB flow resources, control the distribution of IUB incremental flow value to UE, balance empty flow and IUB flux, prevent obstruction of IUB interface and overflows the cache phenomenon.

Description

technical field [0001] The invention relates to flow control technology, in particular to an uplink flow control method. Background technique [0002] High Speed ​​Uplink Packet Access (HSUPA, High Speed ​​Uplink Packet Access) technology is an uplink data transmission enhancement technology formulated by the Third Generation Partnership Project (3GPP), which mainly uses the Hybrid Automatic Repeat Request (HARQ, Hybrid Automatic RetransmissionQuest) technology, base station node (NodeB, Node Base Station) fast scheduling technology and uplink 2ms short frame technology can improve the throughput rate of uplink user data and system uplink capacity. [0003] Since the increase of the uplink air interface rate will directly affect the uplink IUB interface traffic demand, the NodeB generally needs to have a traffic scheduling function to balance the air interface rate and IUB bandwidth and reduce IUB congestion, that is, to control the uplink traffic. [0004] The existing upl...
