Method and device for distributing shared resources in base band pool

Abstract

The invention provides a method and device for distributing shared resources in a base band pool, wherein the method comprises the following steps of calculating the current resource utilization rate of a cell based on an event with changed cell resource use situation, and determining a cell resource assessment upper limit and a cell resource assessment lower limit according to the current resource use situation of a cell group and the current service volume of the cell; and combining the current resource utilization rate of the cell and the calculated cell resource assessment upper limit and the cell resource estimate lower limit to identify whether to active the shared carrier resource of the cell or deactivate the shared carrier resource of the cell. According to the scheme of the invention, the shared resource in the base band pool can be reasonably distributed.

Description

technical field [0001] The invention relates to the allocation technology of shared resources, in particular to a method and a device for allocating shared resources of a baseband pool. Background technique [0002] In order to improve resource utilization, a baseband pool sharing resource technology is introduced in the baseband processing part of the base station (NodeB). There may be multiple baseband pools in each base station, and resources in the baseband pools are shared within the range of the cell group corresponding to the baseband pool in units of carriers; and the shareable carriers in the cell group are auxiliary carriers. [0003] The allocation scheme of the shared resources of the baseband pool in the prior art includes: when the resource usage of a certain cell in the cell group changes, the radio network controller (RNC, Radio Network Controller) calculates the current resource utilization rate of the cell, combined with the preset Judgment is made based o...

Problems solved by technology

If the number of BRUs used in the cell changes between 21 and 31, it will switch back and forth between carrier 1 and carrier 2 non-stop, resulting in a ping-pong effect caused by the unreasonable setting of the upper limit of cell evaluation and the lower limit of cell evaluation, which increases the number of devices load

[0012] It can be seen that using the existing baseband pool shared resource allocation scheme, there is a defect that the shared resources in the baseband pool cannot be reasonably allocated due to the inability to adjust the upper limit of cell resource evaluation and the lower limit of cell resource evaluation in real time according to the actual situation.
