AI Technical Summary

Problems solved by technology

If both RNC and Serving-NB use the throughput of the wireless interface as the flow control standard for sending data, when they send data to Shift-NB at the same time, the data may be congested in the sending buffer of the wireless interface and eventually be lost
Therefore, in the wireless network where there is a logical interface for direct communication between base stations, the reliability of data transmission will be affected due to traffic conflicts in the channel of the wireless bearer.

Embodiment Construction

[0046] The device for controlling the flow of the wireless interface in the wireless network of the present invention, such as figure 1 As shown, the RNC in the wireless network includes an RRC (Radio Resource Controller), and the base station includes a radio interface monitoring function module; the RRC includes a radio bearer control module, which is used to report the information according to the radio interface monitoring function module The measurement report determines the radio bearer adjustment scheme to realize the radio bearer control function, and at the same time reports the determined radio bearer adjustment scheme to the base station through the flow control notification, and the base station adjusts the radio bearer channel according to the adjustment scheme; the wireless interface monitoring function module uses The wireless interface traffic is judged according to the number of transmission data blocks of each channel sent by the base station to the cache.

Abstract

The invention relates to the method and apparatus for controlling wireless interface flow in the wireless network. The method comprises, the base station estimates the number of transmission blocks entering into the buffer of each channel during each transmission interval time, and when the estimated value of the number of transmission blocks of certain channel exceeds the maximum transmission block number that the channel can transmit, the RNC (radio network controller) will perform adjustment to the radio carrying service flow based on the corresponding measurement value. The invention also discloses the apparatus for realizing the method. The invention can guarantee the reliability of the data transmission.

Description

technical field [0001] The invention relates to a wireless network transmission technology, in particular to a method and device for controlling wireless interface traffic in a wireless network. Background technique [0002] With the development of wireless network technology and services, the wireless interface technology suitable for high-speed data communication in the future will be more and more self-adaptive, and the time required for wireless network signaling processing will be further shortened. The base station will terminate more and more signaling closely related to the physical layer of the radio interface, control the process related to service transmission, and undertake part of the radio resource management function separated from the RNC. And there may be a direct transmission channel between the base stations. [0003] Such a logical interface that realizes direct communication between Node-Bs (base stations) is called an IuNB interface. It provides two-w...
