Title
(EN) METHOD FOR MANAGING SHARING OF BASE STATION RESOURCES BY MULTIPLE SLICES
(FR) PROCÉDÉ DE GESTION DE PARTAGE DE RESSOURCES DE STATION DE BASE PAR TRANCHES MULTIPLES
(ZH) 一种多切片共享基站资源的管理方法
Abstract
(EN) The present invention provides a method for managing soft-sharing of base station resources by multiple slices, wherein each slice is allocated with a protection resource Rpx and a protection DRB number Dpx, and the base station at least comprises a list of slices of which the occupied resources exceeds the protection resource. Said method comprises: step 1) receiving a request of a slice x to establish a new service m, the number of DRBs required to be used by the new service m being recorded as Dx, m, and the number of DRBs established by the slice x at a current moment t being recorded as Dox, t; step 2) determining whether the current base station has sufficient free resources to establish the new service m; and step 3) in cases where the current base station does not have sufficient free resources to establish the new service m, if Dox, t+ Dx, m≤ Dpx, triggering the exit of resources for the slices in the slice list of which the occupied resources exceed the protection resource, and after the exit of the resources succeeds, establishing the new service m and the required DRBs, and configuring a protocol stack. On the basis of the embodiments of the present invention, multiple slices share the base station resources, isolation between the slices is ensured, the characteristic of not affecting each other is implemented, and deployment and management costs are reduced.
(FR) La présente invention concerne un procédé de gestion du partage non strict de ressources de station de base par de multiples tranches, chaque tranche se voyant attribuer une ressource de protection Rpx et un nombre Dpx de DRB de protection, et la station de base comportant au moins une liste de tranches dont les ressources occupées dépassent la ressource de protection. Ledit procédé consiste à: étape 1) recevoir une demande d’une tranche x visant à établir un nouveau service m, le nombre de DRB dont le nouveau service m nécessite l’utilisation étant enregistré comme Dx, m, et le nombre de DRB établi par la tranche x à un instant t actuel étant enregistré comme Dox, t; étape 2) déterminer si la station de base actuelle dispose de ressources libres suffisantes pour établir le nouveau service m; et étape 3) dans les cas où la station de base actuelle ne dispose pas de ressources libres suffisantes pour établir le nouveau service m, si Dox, t+ Dx, m≤ Dpx, déclencher la sortie de ressources pour les tranches dans la liste de tranches dont les ressources occupées dépassent la ressource de protection, et après la sortie réussie des ressources, établir le nouveau service m et les DRB nécessaires, et configurer une pile de protocole. Selon les modes de réalisation de la présente invention, de multiples tranches partagent les ressources de station de base, l’isolation entre les tranches est assurée, la caractéristique selon laquelle elles ne s’affectent pas mutuellement est réalisée, et les coûts de déploiement et de gestion sont réduits.
(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。
