参见图 1所示的无线网络维护方法的流程图,该方法以从 AC侧 描述为例进行说明, 其包括以下步骤: 步骤 S102, AC接收 AP按照时间触发或事件触发方式反馈的无 线接入网络状态参数(例如:接入用户数目 , 网络当前的吞吐量等); 其中, 时间触发方式指当 AP的***时钟达到某一时刻时, 触发 上述反馈动作, 例如: 周期性反馈; 事件触发方式为 AP发现某一事 件发生时, 触发上述反馈动作, 例如接收到 AC的指令时进行反馈; 步骤 S104, AC 根据无线接入网络状态参数更新本地存储的该 AP的状态设置参数;
在 AC 上, 可以针对每个 AP 建立一个存储区, 用于存储与该 AP相关的信息, 这些信息可以存放在同一张表格中, 也可以分散放 在几个表格中;
步骤 S106, AC根据更新后的状态设置参数和本地存储的事件更 新策略更新本地存储的该 AP的事件发生状况参数; 其中, 该事件更 新策略指上述状态设置参数与事件发生状况参数的对应关系;
步骤 S108, AC根据更新后的事件发生状况参数维护 AP的无线 网络配置参数。
本实施例的方法中, AC通过 AP反馈的无线接入网络状态参数 更新其状态设置参数,并依据更新后的状态设置参数和本地存储的事 件更新策略更新本地存储的 AP的事件发生状况参数, 进而维护 AP 的无线网络配置参数, 实现依据 AP 的客观情况及时、 动态地维护 AP的无线网络配置参数, 解决了人工维护无线网络存在维护成本较 大、 且故障发生后维修时间较长的问题, 保证了用户无线网络的稳定 性。 本发明实施例中,上述事件发生状况参数可以是针对各个事件的 计数器, 基于此, 上述 AC根据更新后的状态设置参数和本地存储的 事件更新策略更新本地存储的 AP的事件发生状况参数包括: 当 AC 本地存储的 AP的事件发生状况参数为多个不同事件的计数值时, 如 果更新后的状态设置参数满足事件更新策略中对应事件的更新, AC 将该对应事件的计数值加 1。
具体地, 上述 AC才艮据更新后的事件发生状况参数维护 AP的无 线网络配置参数包括: AC 艮据更新后的事件发生状况参数和运营商 预先设置的管理策略判断是否需要对 AP的无线网络配置参数进行调 整; 如果是, AC向 AP下发无线网络配置参数修改命令, 其中, 该 无线网络配置参数爹改命令携带有新的配置参数。 这种方式, 可以实 现 AP配置参数的自动下发, 进而实现 AP配置参数的及时修改, 保 证 AP的正常工作。
考虑到有时需要管理员手动对某个 AP的配置参数进行调整, 基 于此, 上述方法还包括: AC接收管理员手动输入的 AP的无线网络 配置参数修改命令, AC向 AP下发无线网络配置参数修改命令, 其 中, 该无线网络配置参数修改命令携带有新的配置参数。
为了使 AC能够获知 AP是否进行配置参数的更新, 上述方法还 包括: AC接收 AP反馈的配置参数已更新响应报文, 其中, 该配置 参数已更新响应报文中携带有 AP更新后的配置参数; AC更新本地 存储的 AP的配置参数。 该方式下, AC侧始终保持与 AP侧的配置 AC与 AP间的通信使用 CAPWAP ( Control And Provisioning of Wireless Access Points Protocol Specification, 无线接人^、控帝 J与 S己置 协议)。
在实际实现时, 本发明实施例在 AC上设置了一套 CMA无线接 入网络管理软件, 该软件可以才艮据该 AC下管理的无线接入点 AP上 报的当前无线接入网络信息参数, 根据预置的网络管理策略, 自动对 无线接入点配置参数进行修改的网络。 可以实现自动的、 智能的无线 网络管理, 极大地降低网络部署者的网络管理成本。 同时本软件平台 将不依赖于具体的硬件和操作***。
本实施例的 CMA无线接入网络管理软件可以建立在多核心和多 线程嵌入式处理器阵列、 最新的智能分布式计算架构的基础上。 设计 可同时管理 20万台接入站点, 可满足日益苛刻的运营商级大型无线 接入网络管理需求, 为用户提供高效、 智能的网络管理平台。
CMA无线接入网络管理软件, 以实现对无线网络自动化, 智能 化管理为目标设计。 CMA基于目前瘦 AP和 AC的架构, 基于国际 标准的 CAPWAP ( RFC5415 , RFC5416 ) 开发。 CMA无线接入网络 管理软件可以对各无线接入站点周期反馈的网络状态参数进行记录, 存储, 分析。 同时, 才艮据网络运营商提前预制的网络控制策略, 对网 络配置参数进行调整, 对网络进行智能的, 自动的^ 匕。
参见图 2所示的无线网络维护方法的应用场景示意图,该图中的 无线接入网络通过 AP与 AC建立链接, 在该应用场景下, AP与 AC 通过 CAPWAP协议链接, 并才艮据 AC的初始化配置, 建立无线接入 网络,开始对用户服务。各 AP在接入网络建立完成后,通过 CAPWAP 隧道, 向 CMA发送当前 AP配置信息。 CMA对该信息进行存储。 各无线接入网络 AP周期反馈各无线接入网络状态参数(如接入用户 数目, 网络当前吞吐量, 网络当前底噪等)。 这些网络状态参数作为 事件, 由 AC的 CAPWAP模块接收到以后, 发送到 CMA无线接入 管理软件。 此时, CMA无线接入网络管理软件, 根据上报的事件信 息, 自动更新各 AP的状态信息, 同时, ^艮据运营商设置的事件更新 策略, 根据 AP 状态参数, 更新特定事件的发生状况。 随后, CMA 无线接入网络管理软件周期性调用运营商设置的无线网络管理策略, 根据 AP当前的状态参数, 以及 AP当前的特定事件的发生状况, 确 定对该 AP是否进行参数调整, 以及如何进行参数调整。 在做出参数 调整决策后, CMA无线接入网络管理软件, 将指令推送到 CAPWAP 模块, 再由 CAPWAP模块发送到目标 AP上进行配置修改。 目标 AP 在完成爹改后 , 将通过 CAPWAP向 CMA返回执行结果, CMA无线 接入网络管理软件根据返回的执行结果, 更新存储的目标 AP的配置 信息。
对应图 2的应用场景,本发明实施例给出了一种 AC内部结构的 划分方式, 如图 3所示的 AC内部结构示意图, 其中, AC包括: 接 收与发送数据的 CAPWAP模块、 数据搜集模块 (Data Collection ), 事件更新模块( Event Update )、事件更新策略库( Event Update Policy )、 基于 MAC地址的数据存者库 ( Mac - based Recording Database )、 运 营商无线网络管理策略库 ( Action Policy ), 无线网络管理策略执行 ( Policy Execution Core )、手动命令输入模块 ( Manual Command Input ) 和命令发出模块 (Action Delivery ), 其中, 除 CAPWAP模块外的其 余模块对应上述 CMA无线接入网络管理软件。 各个模块功能描述如 下:
( 1 ) 数据搜集模块: 接收并处理 AP上报信息, 将 AP上艮的 字符串信息,通过关键字检索技术,确认信息对应的 AP状态寄存器, 并自动更新该 AP状态寄存器的数值。 并将数值输送到基于 MAC地 址的数据存储库中保管。
( 2 ) 事件更新模块: 将数据搜集模块输出的 AP状态信息, 根 据从事件更新策略库中获取的事件更新策略, 对 AP事件寄存器进行 更新。 并将数值输送到基于 MAC地址的数据存储库中保管。
( 3 ) 事件更新策略库: 用于存储运营商设置的事件更新策略; 事件更新策略中定义了各种事件的判定标准,以及各种事件计数器更 新的算法。 运营商可以在该策略中 , 对 AP General Counters ( AP的 通用计数器) 中的计数器进行读取, 赋值; 对 AP Status Set ( AP的 ^犬态设置参数 ) 以及 AP Configuration ( AP的配置参数 )的值进行读 取。 (注: 此处的事件计数器既为 AP General Counters )。
( 4 ) 基于 MAC地址的数据存储库: 用于存储各 AP的状态信 息, 配置参数信息以及 AP的事件信息。 基于 MAC地址的数据存储 库的具体设计结构: ^图 4所示, 其中 AP的配置信息, ^夫态信息, 以 及事件信息都按照所对应的 AP进行归类, 并通过 AP的 MAC地址 进行区分。 其中, AP的状态设置参数中存放 AP的状态信息; AP的 配置参数中存放 AP的配置信息; AP的通用计数器中存放 AP的事件 信息, 以及其它用于无线网络管理策略的寄存信息。 其中, AP的状 态设置参数根据 AP上报的信息进行自动更新; AP的配置参数通过 AP初始阶段上报的配置信息, 以及在 AP更改配置后的配置反馈信 息, 进行自动更新; AP的通用计数器则根据运营商设置的事件更新 策略, 基于 AP上报的 AP的状态设置参数进行更新; 同时, 也可以 在 CMA无线网络管理软件进行运营商无线网络管理策略时, 才艮据策 略进行修改。
其中, 各计数器都是广义计数器设计, 即每一个计数器的意义是 不确定的, 运营商可以自由的将计数器设计存储不同的信息用途。 例 如, AP的状态设置参数的属性( Attribute ) # 1即可作为当前 AP关 联用户数存储, 也可以作为当前 AP吞吐量存储。 从而为运营商的策 略提供更好的扩张性。
( 5 )运营商无线网络管理策略库: 用于存储运营商设置的无线 网络管理策略; 该无线网络管理策略将才艮据当前 AP的状态信息, 配 置信息, 以及事件信息, 判断对 AP做出那些配置修改。 运营商可以 在该策略中, 对 AP 的通用计数器中的计数值进行读取, 赋值; 对 AP的状态设置参数以及 AP的配置参数的值进行读取。
( 6 ) 无线网络管理策略执行模块: 用于周期性从运营商无线网 络管理策略库中读取存储的运营商无线网络管理策略,并才艮据无线网 络管理策略执行。并向命令发出模块输出根据运营商无线网络管理策 略做出的配置修改命令。
( 7 ) 手动命令输入模块: 用于允许管理员及时地向目标 AP输 入配置修改命令, 对目标 AP进行手工管理配置。 该模块将配置修改 命令输入到命令发出模块。 ( 8 ) 命令发出模块: 将接收到的配置修改命令封装为适当的 CAPWAP信息元素, 交由 CAPWAP模块进行向目标 AP发送。
