Problems solved by technology

Because the existing technology treats all data queues equally, without considering the QOS requirements of the data queues, if there is a data queue with high requirements for GBR (Guaranteed Bit Rate, guaranteed bit rate) in the system, it will be due to insufficient Iub interface bandwidth. , There is less data in the data queue, and the phenomenon of scheduling and emptying occurs, and the guaranteed bit rate configured for the data queue cannot be guaranteed
Because prior art regards the buffer zone of data queue as a static buffer zone, divides the input...

Embodiment Construction

[0022] The embodiment of the present invention proposes a bandwidth allocation control method and device. The method and device are based on the average rate of the air interface of the current subframe of the user data queue, the benchmark of the bandwidth of the Iub interface configured for the current subframe of the user data queue and the average rate of the air interface Ratio F1 and user delay suppression factor F2 determine the Iub interface bandwidth Bw1 required by the user data queue in the current subframe; when Bw1 meets the guaranteed bit rate requirements configured for the user data queue, according to the current The total bandwidth of the Iub interface required in the subframe and the total bandwidth range of the Iub interface that can be allocated will adjust the F1 configured for the current subframe of the user data queue to the current subframe F1, and will The F2 configured for the current subframe of the user data queue is adjusted to the current subfram...

Abstract

The invention discloses a bandwidth allocation control method and a device thereof, which are used to reasonably allocate Iub interface bandwidth for a user data queue and to ensure the guaranteed bit rate allocated to the user data queue. The method includes the following steps: according to the average speed R of the air interface of the current subframe of the user data queue, the base ratio F1 of the Iub interface bandwidth allocated for the current subframe of the user data queue and the average speed of the air interface, and a user time delay restraint factor F2, determining the Iub interface bandwidth Bw1 requested in the current subframe of the user data queue; when the Iub interface bandwidth Bw1 satisfies the requirement of the guaranteed bit rate, adjusting the base ratio F1 allocated to the current subframe of the user data queue to be current subframe F1, and adjusting the user time delay restraint factor F2 allocated to the current subframe of the user data queue to be current subframeF2; and allocating Iub interface bandwidth for the user data queue according to R, the current subframeF1 and the current subframeF2.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a bandwidth allocation control technology. Background technique [0002] The 3GPP25.435 (3GPP: 3rd Generation Partnership Project, the third generation communication cooperation organization) agreement stipulates that in the HSDPA (High Speed ​​Downlink Packet Access, high-speed downlink packet access) system, the RNC (Radio Network Controller, radio network controller) Use HS-DSCH (High Speed ​​Downlink Shared Channels, High Speed ​​Downlink Shared Channel) to transmit high-speed downlink data to the base station. [0003] MAC-d (MAC-dedicated, dedicated MAC) is a type of MAC (Medium Access Control, medium access control) entity, located at the RNC side, and used to process dedicated channels. And MAC-hs (MAC-high speed, high-speed MAC) is also a MAC entity, located at the side of the base station, and used to process the HS-DSCH. HS-DSCH uses the following procedure fo...
