Title
(EN) Management method for multi-slice shared base station resources
(ZH) 一种多切片共享基站资源的管理方法
Abstract
(EN) The invention provides a management method of multi-slice soft sharing base station resources. A protection resource Rpx and a protection DRB number Dpx are allocated to each slice; the base station at least comprises a slice list with occupied resources exceeding protection resources. The method comprises the following steps: step 1) receiving a request of establishing a new service m by a slicex, marking the number of DRBs required to be used by the new service m as Dx, m, and marking the number of DRBs established by the slice x at the current moment t as Dox, t; 2) judging whether the current base station has enough idle resources to establish a new service m; 3) under the condition that the current base station does not have enough idle resources to establish a new service m, if Dox,t + Dx, m is less than or equal to Dpx, triggering the slices belonging to the slice list of which the occupied resources exceed the protection resources to exit the resources, establishing the new service m and the required DRB after the resources exit successfully, and configuring a protocol stack. Based on the method disclosed in the embodiment of the invention, the base station resources areshared by multiple slices, the isolation among the slices is ensured, a characteristic of no mutual influence is realized, and the deployment and management cost is reduced.
(ZH) 本发明提供一种多切片软共享基站资源的管理方法,其中所述每个切片分配有保护资源Rpx和保护DRB数Dpx,所述基站至少包括一个占用资源超过保护资源的切片列表,包括:步骤1)接收切片x建立新业务m的请求,所述新业务m需要使用的DRB数记为Dx,m,切片x在当前时刻t已建立的DRB数记为Dox,t;步骤2)判断当前基站是否有足够空闲资源建立新业务m;步骤3)在当前基站没有足够空闲资源建立新业务m情况下,如果Dox,t+Dx,m≤Dpx,则对属于占用资源超过保护资源的切片列表中的切片触发退出资源,在所述资源退出成功后,建立新业务m以及其所需DRB,并配置协议栈。基于本发明的实施例,实现多切片共享基站资源,保证切片间隔离性,实现互不影响的特性,降低部署和管理成本。
