计算模块, 其设置为: 根据所述相关参数计算 DRB弃包率, 其中, 下行 DRB反传数据不参与 DRB弃包率的计算。
7、 根据权利要求 6所述的装置, 其中, 所述统计模块是设置为在所述源 小区激活后, 统计每个服务质量类别标识 QCI等级的无线承载上, 在预定周 期内, 该小区收到的所有下行 DRB数据包数、 下行 DRB弃包数以及下行反 传 DRB数据包数。
8、 根据权利要求 3所述的方法, 其中, 所述计算模块是设置为根据如下公 式计算该小区的 DRB弃包率:
Ddisc(T, qci)* 1000000
M(T,qci) = 其中, Μ(Γ, qci)表示任一 QCI等级的无线
N(T,qci)-NX2(T,qci) 承载上, 在预定周期内的 DRB弃包率, N(7^d)表示所述源小区收到的所有 下行 DRB数据的包数、 Ni2(r, c)表示下行反传 DRB数据包数、 DdisclT'qcP)表 示下行 DRB弃包数。
9、 根据权利要求 6所述的方法, 其中, 所述统计模块是设置为在所述源 小区激活后, 统计每个 QCI等级的无线承载上, 在预定周期内, 所述源小区 的下行 DRB弃包数、 混合自动重传请求( HARQ )成功的下行 DRB数据包 数以及 HARQ失败的 DRB数据包数。
10、 根据权利要求 9所述的方法, 其中, 所述计算模块是设置为根据如 下公式计算该小区的 DRB弃包率:
Ddisc(T, qci) * 1000000
M(T, qci) -- 其中, M(J, d)表示任一 QCI
N(T, qci) + Dloss(T, qci) + Disc( qci) 等级的无线承载上, 在预定周期内的 DRB弃包率, Z¾foc(r,^0表示所述源小 区的下行 DRB 弃包数、 N(T, qCP)表示 HARQ成功的下行 DRB数据包数、 D!oss(T,qcP>表示 HARQ失败的下行 DRB数据包数。
