Method and system for controlling Iub interface band width resource in wireless network

Abstract

The invention relates to mobile telecommunications technology, discloses control methods and systems of bandwidth resources of Iub interface in wireless network, so that the use of Iub bandwidth resource are effectively controlled and further ease the congestion problem of Iub interface. In the invention, if it is still unable to solve the congestion problem of Iub interface after reduce the speed of business of which priority level below that of voice business, then select part of UE using AMR business, and reduce the speed of AMR business of the selected UE to release the congestion problem of Iub interface. When using the UE of AMR businesses choose according to UE business priorities and business rate, generally first reduce the speed of users with lower priority to ensure the service quality of high-priority users. Reduce the speed of high speed UE if they have the same priority level, this would have good deceleration effect with less users affected.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to the control technology of Iub interface bandwidth resource. Background technique [0002] Wideband Code Division Multiple Access (WCDMA for short) is one of the international standards for third-generation mobile communications in the world accepted by the International Telecommunications Union (ITU for short). It can also be said to be the first third-generation mobile communication system put into commercial use in the world, and it is also the frequency division duplex (Frequency Division Duplex, FDD for short) frequency band standard of the third-generation mobile communication system in Europe. Since the Universal Mobile Telecommunications System ("UMTS" for short) adopts the WCDMA air interface technology, the UMTS system is usually also referred to as the WCDMA communication system. [0003] The UMTS system adopts a structure similar to that of the second-generation mobi...

AI Technical Summary

Problems solved by technology

[0011] In actual application, the above-mentioned scheme has the following problems: after adopting the existing algorithm to reduce the rate of BE business, under the situation that the Iub interface bandwidth resource is still insufficient, it is impossible to further release the Iub interface resource, alleviate or remove the Iub congestion situation

However, when the congestion on the Iub interface is serious, it may not be possible to further alleviate or relieve the congestion on the Iub interface only by reducing the BE service rate.
