具体地,当所属所述第一组公共陆地移动网络PLMN GROUP1的公共陆地移动网络PLMN1能提供正常的公共安全业务时,基站2在所属所述第一组公共陆地移动网络PLMN GROUP1的小区里广播所述PLMN1,且所属所述第一组公共陆地移动网络PLMN GROUP1下的所有移动台1连接到远程核心网EPC1上来获取正常的公共安全业务,并断开与本地核心网4的连接。
步骤14:基站2与远程核心网EPC3之间的S1链路连接恢复正常。
步骤15:基站2在配置了所属所述第二组公共陆地移动网络PLMN GROUP2的PLMN的小区里广播PLMN3,所述第二组公共陆地移动网络PLMN GROUP2退出故障弱化模式。
步骤16:所属所述第二组公共陆地移动网络PLMN GROUP2的移动台1连接到远程核心网EPC3来获取正常的公共安全业务,并断开与本地核心网4的连接。
具体地,当所属所述第二组公共陆地移动网络PLMN GROUP2的公共陆地移动网络PLMN 3能提供正常的公共安全业务时,所述第二组公共陆地移动网络PLMN GROUP 2退出故障弱化模式,基站2在所属所述第二组公共陆地移动网络PLMN GROUP 2的PLMN的小区里广播所述PLMN 3。
步骤17:基站2断开与本地核心网4之间的S1链路连接。
具体地,当所属所述第一组公共陆地移动网络PLMN GROUP 1的一个公共陆地移动网络PLMN能提供正常的公共安全业务,且所属所述第二组公共陆地移动网络PLMN GROUP 2的公共陆地移动网络PLMN3能提供正常的公共安全业务时,基站2释放与本地核心网4之间的S1链路连接。
也就是说,当远程核心网EPC1或者EPC2与基站2之间的S1链路连接故障恢复时,所述第一组公共陆地移动网络PLMN GROUP 1退出IOPS故障弱化模式,而所述第二组公共陆地移动网络PLMN GROUP 2仍处于IOPS故障弱化模式;当远程核心网EPC 3与基站2之间的S1链路连接故障也恢复时,所述第二组公共陆地移动网络PLMN GROUP 2退出IOPS故障弱化模式,此时基站2释放与本地核心网4的S1链路连接,即,此时基站2断开与本地核心网4之间的S1链路。
请参阅图8,是本发明网络节点的结构示意图。所述网络节点11包括通信部件111,用于与其他通信设备进行通信;存储器112,用于存储程序;与所述存储器112耦合的处理器113,运行所述存储器112中存储的程序时,执行上述的方法。
本发明的集群通信故障弱化***及方法包括基站2,配置有至少两组公共陆地移动网络;与所述至少两组公共陆地移动网络对应的远程核心网3,在一组远程核心网与所述基站的S1链路连接均发生故障时,该组公共陆地移动网络进入故障弱化模式;本地核心网4,在该组公共陆地移动网络进入故障弱化模式时, 所述基站2与本地核心网4建立S1链路连接以为所属该组公共陆地移动网络的移动台1提供服务,以及基于以上***的集群通信故障弱化方法来降低网络物理链路或者设备故障对通信的影响。
以上所述仅为本发明的实施方式,并非因此限制本发明的专利范围,凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本发明的专利保护范围内。
