其中, 当 PLMN接入权限参数为接入允许优先级信息时, 可以包括: 根据该接入允许优先级信息判断得出自身支持的 PLMN中优先级最低的 PLMN作为需要禁止接入共享网络的终端所属的 PLMN。 例如接入允许优先级 信息可以为 PLMN1 >PLMN2>PLMN3 , 因此, eNB应首先禁止 PLMN3中的终端接 入共享网络。
其中, 当 PLMN接入权限参数为禁止优先级信息时, 可以包括: 根据该接入禁止优先级信息判断得出自身支持的 PLMN中禁止优先级最 高的 PLMN作为所述需要禁止接入共享网络的终端所属的 PLMN。例如接入禁 止优先级信息为 PLMN3>PLMN2>PLMN1 , 因此, eNB应首先禁止 PLMN3中的终 端接入共享网络。
其中, 当 PLMN接入权限参数为接入允许百分比参数或接入禁止百分比 参数时, 可以包括:
根据接入允许百分比参数或接入禁止百分比参数确定需要禁止接入共 享网络的终端所属的 PLMN ,并确定上述 PLMN中的终端在被禁止接入所述共 享网络的终端中所占的百分比; 例如以接入禁止百分比参数为 "PLMN1 20% , PLMN2 50% , PLMN 3 30%" 为例进行说明, 则当前 eNB应该确定得到: 分别 禁止 PLMN1、 PLMN2、 PLMN3 中的部分终端接入, 且被禁止接入共享网络的 PLMN PLMN2 , PLMN 3的终端的数量应分别占被禁止接入共享网络的终端总 数的 20%、 50%、 30%。

具体地, 当终端判断得出自身的 AC值与禁止接入信息中的 AC值相同, 且终端属于上述确定的 PLMN时, 不能通过当前 eNB连接共享网络, 以减少 当前 eNB的负载; 或者, 终端根据 eNB广播的 AC值和接入禁止因子通过计 算获知自身是否被禁止接入当前共享网络。
其中, 终端根据 eNB广播的 AC值和接入禁止因子通过计算获知自身是 否被禁止接入当前共享网络, 可以包括:

需要说明的是, 当上述确定的 PLMN中的终端被禁止接入共享网络后, 当前 eNB仍然负载过重, 则按照步骤 402中的方法确定下一个符合 PLMN接 入权限参数的 PLMN作为禁止接入共享网络的 PLMN。
另外, 当在步骤 403中 eNB指示接入禁止信息适用于上述确定的 PLMN 和上述确定的 PLMN中的终端在被禁止接入共享网络的终端的总数中所占的 百分比时, 本步骤可以为:
终端才艮据接入禁止信息、 上述确定的 PLMN和上述确定的 PLMN中的终 端在被禁止接入所述共享网络的终端的总数中所占的百分比进行计算, 判 断自身是否被禁止接入共享网络。
