本发明的较佳实施方式 结合附图及较佳实施例， 对本发明提出的所述 LTE***中网管与基站的协作 方法和装置， 详细说明 ¾口后。
本发明第一实施例， 如图 4所示， 一种 LTE***中网管与基站的协作方 法， 包括如下具体步骤：
步骤 S101 , 在 LTE ***开局或升级时， 所有基站通过设置在网管中的
DHCP ( Dynamic Host Configuration Protocol, 动态主机设置协议）服务器获 取自身的 IP地址， 地理位置邻近的基站处于同一个网段。 这个 IP地址必须 要从网管处获得， 这样网管便知道地址规划情况， 并可实时地和任意一个基 站建立实连接。
步骤 S102,所有基站获取 IP地址后主动和网管建立实连接，只有建立实 连接的网络设备之间才有链路保活消息。
步骤 S103 , 将地理位置邻近的基站设为一组， 成为一个逻辑区域， 如图 2 所示， 圓形虚线包围的左右两组基站。 由于地理位置邻近的基站处于同一 个网段， 同一网段的基站之间通讯不需要路由转发， 在网内完成数据的传送， 减少了对其他网段的影响。
步骤 S104, 在每个逻辑区域中任意选择一台基站作为管理基站， 为其配 置高级权限， 其余基站为被管理基站。 权限配置的越细致， 管理基站就越能 分担网管的工作， 整个***的性能瓶颈就能得到充分的分解释放。
步骤 S105 , 网管将其与被管理基站的实连接转换为虚连接， 网管与管理 基站保持实连接， 如图 3所示。 此处虚连接是指从网管上看被管理基站仍然 与网管保持着连接， 但没有实际的链路， 被管理基站的必要信息， 例如保活 链路消息等是通过管理基站上报到网管， 在网管上对被管理基站操作都是先 传送到管理基站上， 再下发到被管理基站上。
步骤 S106, 网管将开局信息下发到管理基站， 该开局信息包括基站需要 下载的软件版本和配置数据。
步骤 S107 , 被管理基站从管理基站处获取开局信息；
步骤 S108,管理基站对被管理基站上报的告警消息，性能测量数据消息， 链路保活消息， 以及软件版本和配置数据请求消息进行判断处理， 包括： 当管理基站收到告警消息时， 判断在设定的时间内是否已有同样的告警 消息上报， 若有， 则过滤掉所述告警消息， 若没有， 则将所述告警消息上报 给网管；
例如： 链路断告警信息， A、 B两个基站之间建立连接关系， 当 A上链 路处理模块出现故障时， 会导致 AB之间的链路断， 此时 A上报链路故障告 警， 在短时间内当管理基站再接收到 B 上报的 AB链路断告警时， 就可忽略 此告警信息。
当管理基站收到性能测量数据消息时， 根据当前网络流量情况， 对性能 测量数据消息进行保存延迟发送或者立即发送；
管理基站将一段时间内收到的链路保活消息中的信息汇总后， 合为一条 链路保活消息上报给网管；
当管理基站收到软件版本和配置数据请求消息时， 将软件版本和配置数 据发送给被管理基站。
本发明第二实施例， 如图 5所示， 一种 LTE***中网管与基站的协作 方法， 包括如下具体步骤：
步骤 S201 , 在 LTE***开局或升级时， 网管利用本地维护终端通过本地 连接给所有基站配置 IP地址。 这个 IP地址必须要从网管处获得， 这样网管 便知道地址规划情况， 并可实时地和任意一个基站建立实连接。
步骤 S202,所有基站获取 IP地址后主动和网管建立实连接，只有建立实 连接的网络设备之间才有链路保活消息。
步骤 S203 , 将接入同一网络设备的基站设为一组， 成为一个逻辑区域。 步骤 S204, 在每个逻辑区域中任意选择一台基站作为管理基站， 为其配 置高级权限， 其余基站为被管理基站。 权限配置的越细致， 管理基站就越能 分担网管的工作， 整个***的性能瓶颈就能得到充分的分解释放。
步骤 S205, 网管将其与被管理基站的实连接转换为虚连接， 网管与管理 基站保持实连接。 此处虚连接是指从网管上看被管理基站仍然与网管保持着 连接， 但没有实际的链路， 被管理基站的必要信息， 例如保活链路消息等是 通过管理基站上报到网管， 在网管上对被管理基站操作都是先传送到管理基 站上， 再下发到被管理基站上。
步骤 S206, 网管将开局信息下发到管理基站， 该开局信息包括基站需要 下载的软件版本和配置数据。
步骤 S207, 被管理基站从管理基站处获取开局信息；
步骤 S208,管理基站对被管理基站上报的告警消息，性能测量数据消息， 链路保活消息， 以及软件版本和配置数据请求消息进行判断处理， 包括： 当管理基站收到告警消息时， 判断在设定的时间内是否已有同样的告警 消息上 若有， 则过滤掉所述告警消息， 若没有则将所述告警消息上 ^艮给 网管；
例如： 链路断告警信息， A、 B两个基站之间建立连接关系， 当 A上链 路处理模块出现故障时， 会导致 AB之间的链路断， 此时 A上报链路故障告 警， 在短时间内当管理基站再接收到 B 上报的 AB链路断告警时， 就可忽略 此告警信息。
当管理基站收到性能测量数据消息时， 根据当前网络流量情况， 对性能 测量数据消息进行保存延迟发送或者立即发送；
管理基站将一段时间内收到的链路保活消息中的信息汇总后， 合为一条 链路保活消息上报给网管；
当管理基站收到软件版本和配置数据请求消息时， 将软件版本和配置数 据发送给被管理基站。
步骤 S209, 当网管发现管理基站出现故障时， 主动与该管理基站所在的 逻辑区域内的被管理基站建立实连接， 网管重新在所述管理基站所在的逻辑 区域内选择一台基站作为管理基站。
本发明第三实施例， 如图 6所示，一种 LTE***中网管与基站的协作方 法， 与第二实施例大致相同， 区别在于，
步骤 S309, 当被管理基站发现管理基站出现故障时， 主动与网管建立实 连接， 网管重新在所述管理基站所在的逻辑区域内选择一台基站作为管理基 站。
例如， 一种典型的情况就是当被管理基站上报的信息在管理基站总被过 滤掉后， 被管理基站认为管理基站处在不正确地状态， 从而主动发起与网管 建立连接， 上报信息。
本发明第四实施例， 如图 7所示，一种 LTE***中网管与基站的协作装 置， 包括如下组成部分：
网管， 其设置成将基站配置为管理基站和被管理基站， 并将开局信息下 发到管理基站。 网管包括如下三个模块：
建立连接模块， 其设置成为所有基站分配 IP地址， 并与所有基站建立实 连接；
权限配置模块， 其设置成将地理位置邻近的基站划分为一个逻辑区域， 在每个逻辑区域中选择一台基站作为管理基站， 为其配置高级权限， 其余基 站为被管理基站；
初始化模块， 其设置成将网管与被管理基站的实连接转换为虚连接， 同 时保持网管与管理基站的实连接， 并将开局信息下发到管理基站， 该开局信 息包括软件版本和配置数据。网管只与建立实连接的基站保持链路保活消息， 管理基站和被管理基站之间保持链路保活消息， 这样有效减少基站和网管之 间的链路保活消息。
被管理基站， 其设置成通过管理基站向网管上报告警消息、 性能测量数 据消息、 链路保活消息以及软件版本和配置数据请求消息， 从管理基站处获 取开局信息。 管理基站， 其设置成对被管理基站上报的消息进行判断处理， 包括： 当管理基站收到告警消息时， 判断在设定的时间内是否已有同样的告警 消息上报， 若有， 则过滤掉所述告警消息， 若没有则将所述告警消息上报给 网管；
当管理基站收到性能测量数据消息时， 根据当前网络流量情况， 对性能 测量数据消息进行保存延迟发送或者立即发送；
管理基站将一段时间内收到的链路保活消息中的信息汇总后， 合为一条 链路保活消息上报给网管；
当管理基站收到软件版本和配置数据请求消息时， 将软件版本和配置数 据发送给被管理基站。
本发明第五实施例， 如图 7所示，一种 LTE***中网管与基站的协作装 置， 包括如下组成部分：
网管， 其设置成将基站配置为管理基站和被管理基站， 并将开局信息下 发到管理基站。 网管包括如下三个模块：
建立连接模块， 其设置成为所有基站分配 IP地址， 并与所有基站建立实 连接；
权限配置模块， 其设置成将接入同一个网络设备的基站划分为一个逻辑 区域， 在每个逻辑区域中选择一台基站作为管理基站， 为其配置高级权限， 其余基站为被管理基站；
初始化模块， 其设置成将网管与被管理基站的实连接转换为虚连接， 同 时保持网管与管理基站的实连接， 并将开局信息下发到管理基站， 该开局信 息包括软件版本和配置数据。网管只与建立实连接的基站保持链路保活消息， 管理基站和被管理基站之间保持链路保活消息， 这样有效减少基站和网管之 间的链路保活消息。
被管理基站， 其设置成通过管理基站向网管上报告警消息、 性能测量数 据消息、 链路保活消息以及软件版本和配置数据请求消息， 从管理基站处获 取开局信息。 管理基站， 其设置成对被管理基站上报的消息进行判断处理， 包括： 当管理基站收到告警消息时， 判断在设定的时间内是否已有同样的告警 消息上报， 若有， 则过滤掉所述告警消息， 若没有， 则将所述告警消息上报 给网管；
当管理基站收到性能测量数据消息时， 根据当前网络流量情况， 对性能 测量数据消息进行保存延迟发送或者立即发送；
管理基站将一段时间内收到的链路保活消息中的信息汇总后， 合为一条 链路保活消息上报给网管；
当管理基站收到软件版本和配置数据请求消息时， 将软件版本和配置数 据发送给被管理基站。
本发明还提供 LTE***中网管和基站， 其具体用法见上述装置， 在此不 再重复。
LTE ***与 3G***相比， 由于***架构的变化， 导致关键网络节点设 备处理数据的能力要求很高， 本发明为降低对汇聚端网络节点设备的冲击， 按照组网方式设置权限与管理范围，在 LTE ***中给网管管理下的某些基站 设置特定的权限， 具有某些权限的基站可以管理没有权限或权限等级较低的 基站 ， 承担网管的部分工作， 这样保证在开局过程中版本下载及配置数据在 下发给某些权限的基站后， 其它基站可以并发获取版本和数据。
在***运行过程不必要的信息在中间基站上过滤处理掉， 必要的信息实 时地、 可靠地传送到网管， 网管进行决策处理。 同时这种权限的设置是多层 次多模式的， 可以灵活设置， 比如， 当***中设置高低不同的权限时， 网管 通过管理高权限的基站， 高权限的基站管理较低权限的基站进而管理所有基 站的管理模式。 还可以兼容现有技术中 LTE的扁平化管理结构， 将所有基站 都设置最高权限或不设置权限， 网管就对所有基站进行管理维护，
使用本发明的技术方案， 在下载软件版本及配制数据时极大减少了网管 传送的信息量， 降低了对网络结点设备的冲击， 整个***启动过程提速， 节 约了***从初始化到正常工作的时间； 在***运作过程中， 有效地减少了网 管和基站之间的链路保活消息， 在权限较高的基站上对上报的告警、 性能测 量等数据经过相应的处理， 必要的信息经过处理后上报到网管， 不必要的信 息过滤掉。 降低了链路保活消息、 告警信息、 性能测量等数据占用网络带宽 时的相互影响， 提高了网管处理数据的实时性。
通过具体实施方式的说明， 应当可对本发明为达成预定目的所釆取的技 术手段及功效得以更加深入且具体的了解， 然而所附图示仅是提供参考与说 明之用， 并非用来对本发明加以限制。
工业实用性
与现有技术相比， 本发明在下载软件版本及配置数据时极大减少了网管 传送的信息量， 降低了对网络结点设备的冲击， 整个***启动过程提速， 节 约了***从初始化到正常工作的时间。
