Problems solved by technology

When the Nodeb and the RNC are connected through E1, the Nodeb is connected to the aggregation device (such as a switch) through E1. Since the E1 transmission of the Iub port is not connected end-to-end, when some E1s between the Nodeb and the switch are broken, the actual The transmission bandwidth becomes smaller, but the E1 between the RNC and the switch is still normal, the transmission bandwidth of the RNC does not change, and the RNC cannot perceive the change of the transmission bandwidth of the Nodeb, so the transmission bandwidth of the RNC and the Nodeb is inconsistent, and the RNC performs the downlink The transmission bandwidth of admission control and back pressure is inaccurate, which causes Nodeb to be unable to process the data sent by RNC, resulting in Iub port congestion

Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0029] In order to solve the problem that the RNC cannot obtain the transmission bandwidth information of the Nodeb in the prior art, and thus when the Iub port E1 fails, the RNC cannot perform downlink admission control and backpressure bandwidth threshold according to a reasonable transmission bandwidth, and then the problem of Iub port congestion occurs, Embodiments of the present invention provide a transmission bandwidth reporting method, device and system...

Abstract

The invention discloses a transmission bandwidth reporting method, a device and a system. The method comprises the step that a base station receives an audit request message sent by a wireless network controller RNC, and an audit response message is fed back to the RNC; and the audit response message carries the identification information of all physical ports of the base station and the current effective transmission bandwidth information of all physical ports. The device comprises a message receiving unit and a message feedback unit. According to the invention, the bandwidth information is added in the audit response message in an NBAP protocol; an Nodeb actively reports real-time physical transmission bandwidth to the RNC, so that the RNC adjusts Iub interface downlink admission control and the transmission bandwidth of back pressure; the utilization efficiency of Iub interface bandwidth is improved; and Iub interface congestion is avoided.

Description

technical field [0001] The present invention relates to the technical field of WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access) mobile communication, in particular to a transmission bandwidth reporting method, device and system. Background technique [0002] With the evolution of the 3GPP (The 3rd Generation Partnership Project, Third Generation Partnership Project) protocol, the transmission connection between Nodeb (base station) and RNC (Radio Network Controller) is very complicated, and the transmission medium is also diverse . When the Nodeb and the RNC are connected through E1, the Nodeb is connected to the aggregation device (such as a switch) through E1. Since the E1 transmission of the Iub port is not connected end-to-end, when some E1s between the Nodeb and the switch are broken, the actual The transmission bandwidth becomes smaller, but the E1 between the RNC and the switch is still normal, the transmission bandwidth of the R...
