摘要
针对移动互联网业务流量激增,无线运营商在网络建设、运营、升级等方面的支出不断增加而收入却增加缓慢的问题,论文研究了基于集中式基带资源池的云型无线接入网(C-RAN),提出C-RAN架构下基带处理单元(Building Base-band Unit,BBU)与远端无线射频单元(Radio Remote Unit,RRU)组成的动态映射的模型,以此模型设计基带资源分配方法。通过计算与分析,结果表明利用启发式降序首次适应算法作为预分配的算法,对基带资源进行了合理的分配,这对于提高基带资源的利用率并且减少电能消耗是实际可行的。
Aim to cost of wireless operators constantly increases but income increases slowly,this paper researches cloud wireless access network(C-RAN)based on concentrated resources pool,proposes a dynamic projection model combined with base band processing unit(Building Base band Unit,BBU)and remote radio unit(Radio Remote Unit,RRU),designs base band resource allocation method,according to cloud calculation and C-RAN technology which is introduced in this paper,through calculation and analysis,results show that using heuristic order-decreasing first-fit algorithm as the pre-allocation algorithm can distribute base band resource properly and realize dynamic scheduling under C-RAN,which is practical and feasible to improve utilization of base band resource and reduce power consumption.
