综上所述, 本发明实施例提供的 WTP管理方法, 通过唯一的网络地址与 WTP建立连接, AC管理设备用于管理至少 1个接入控制器 AC; AC管理设备 向 WTP提供至少 1个 AC的连接信息,以便 WTP根据获取到的连接信息与至 少 1个 AC建立连接; 解决了在目前技术下, WTP获取与 AC相关的先验信息 和初始化条件是较为困难的问题; 达到了 WTP通过 AC管理设备就能够发现 AC并且和 AC建立连接的效果。 由于 WTP可以通过两种方式从 AC管理设备获取 AC的连接信息, 来帮 助 WTP发现 AC并建立连接: 1、 WTP从 AC管理设备获取至少 1个 AC的连 接信息; 2、 WTP从 AC管理设备获取至少 1个 AC的连接信息和管理区域。
请参考如 5A,其示出了本发明另一个实施例提供的 WTP接入方法的方法 流程图。 本实施例主要以该 WTP接入方法应用于图 2所示实施环境, 且 WTP 从 AC管理设备获取至少 1个 AC的连接信息来举例说明。该 WTP接入方法, 包括:
步骤 501 , WTP通过唯一的网络地址与 AC管理设备建立连接;
AC管理设备用于管理至少 1个 AC, WTP通过唯一的网络地址与 AC管 理设备建立连接, 也可以认为是 AC管理设备通过唯一的网络地址与 WTP建 立连接, 且该连接可以为基于 CAPWAP协议扩展的 CAPWAP扩展隧道连接。 具体来讲, 本步骤包括但不限于如下子步骤, 参考图 5B所示:
501a, WTP检测是否支持与 AC管理设备连接;
WTP首先启动, 并进入 IDLE状态 (空闲状态), 如图 5C所示。 在 IDLE 状态下, WTP检测是否支持与 AC管理设备连接。 也即, WTP检测自身是否 具备和 AC管理设备连接的条件以及是否支持该功能, 该条件包括配置信息、 搜索能力等中的一种或几种。
501b, 若检测结果为 WTP支持与 AC管理设备连接, 则 WTP通过唯一的 网络地址向 AC管理设备发送连接请求;
唯一的网络地址是指能够使 WTP找到 AC管理设备的地址, 可以是包括 但不限于预先设定的唯一 DNS域名或是 IP地址中的任何一种或几种。优选地, WTP还在连接请求中携带鉴权信息。 若检测结果为 WTP支持与 AC管理设备 连接时, 由 IDLE状态进入 ACS CONN ( AC管理设备连接)状态, 并通过唯 一的网络地址向 AC管理设备发送连接请求。
对应地, AC管理设备接收 WTP通过唯一的网络地址发送的连接请求。优 选地, AC管理设备接收到 WTP发送的连接请求之后, 需要对 WTP连接请求 中所携带的鉴权信息进行鉴权。
501c, AC管理设备在接收到连接请求后向 WTP反馈连接响应;
AC管理设备接收到 WTP发送的连接请求之后, 向 WTP反馈连接响应。 优选地, AC管理设备要对 WTP连接请求中所携带的鉴权信息进行鉴权,且在 该鉴权信息能够通过 AC管理设备的鉴权时, AC管理设备向 WTP发送连接响 应, 在该连接响应中携带鉴权结果。
501d、 WTP接收 AC管理设备针对连接请求反馈的连接响应;
若 WTP没有收到 AC管理设备的连接响应,则 WTP会每隔预定时间间隔 继续向 AC管理设备发送连接请求, 直到接收到 AC管理设备的连接响应。
但是当 WTP向 AC管理设备重新发送的连接请求次数达到最大重传次数 的时候, 仍然没有收到 AC管理设备的连接响应, 则 WTP会停止发送连接请 求, 并且由 ACS CONN状态进入 SULKING状态(等待状态)。 最大重传次数 是指一个已经预定好的阈值。
WTP停止发送连接请求之后,会等重连超时之后,会重新由 SULKING状 态进入 ACS CONN状态, 然后继续向 AC管理设备发送连接请求。 等待重连 超时是指一个已经预定好的阈值。
501e、 WTP在接收到连接响应后, 与 AC管理设备通过无线接入点协议 CAPWAP的扩展隧道建立连接;
WTP在接收到连接响应后,与 AC管理设备通过无线接入点协议 CAPWAP 的扩展隧道建立连接。 换句话说, AC管理设备在 WTP接收到连接响应后, 与 WTP建立无线接入点协议 CAPWAP的扩展隧道连接。
步骤 502, WTP与 AC管理设备进行初始信息交互;
WTP与 AC管理设备之间通过 CAPWAP扩展隧道建立连接之后, WTP与 AC管理设备之间就可以进行信息的交互。 具体来讲, 本步骤包括但不限于如 下子步骤:
1、 WTP向 AC管理设备上报配置状态等信息;
比如, 配置状态等信息包括 WTP所属的无线信道等信息。
对应地, AC管理设备接收 \\01)上^艮的配置状态等信息,生成配置状态响 应。
2、 AC管理设备将配置状态响应反馈给 WTP;
对应地, WTP接收 AC管理设备反馈的配置状态响应;
若 WTP的位置发生变化, 或所处的信道发生改变, WTP需要将改变后的 配置状态向 AC管理设备上报, 以便 AC管理设备接收 WTP改变后的配置状 态, 并根据该配置状态生成响应, 并将该响应反馈给 WTP, 实现在 AC管理设 备上对 WTP信息的及时更新。 步骤 503 , WTP向 AC管理设备上 WTP的地理位置和 /或鉴权信息; 由于 WTP要发现周围可连接的 AC, 需要通过 AC管理设备查找 WTP周 围的 AC, 因此需要将自己的地理位置上报给 AC管理设备。 地理位置可以是 WTP的物理地址, 该物理地址可以用大地坐标或经纬度来表示。 鉴权信息可 以用来指示 WTP属于哪个网络运营商。
对应地, AC管理设备接收 WTP上 ^艮的 WTP的地理位置和 /或鉴权信息。 步骤 504, AC管理设备向 WTP提供至少 1个 AC的连接信息。
在本步骤中, AC管理设备向 WTP提供 AC的连接信息可以有三种实现方 式: 第一种, AC管理设备可以根据 WTP的地理位置向 WTP提供 AC的连接 信息; 第二种, AC管理设备还可以根据 WTP的鉴权信息向 WTP提供 AC的 连接信息; 第三种, AC管理设备根据 WTP的地理位置和鉴权信息两者的结合 向 WTP提供 AC的连接信息;
具体来讲, 第一种, AC管理设备根据 WTP的地理位置向 WTP提供至少 1个 AC的连接信息, 至少 1个 AC中的每个 AC的管理区域均覆盖 WTP的地 理位置, 连接信息包括静态地址、 广播域地址、 标识信息和 DNS信息中的至 少一种。 具体来讲, 本步骤包含但不限于如下子步骤:
1、 AC管理设备在至少 1个 AC中查询管理区域覆盖 WTP地理位置的至 少 1个 AC;
2、 AC管理设备将查询到的至少 1个 AC的连接信息发送给 WTP;
对应地, WTP从 AC管理设备获取至少 1个 AC的连接信息, 也即 WTP 接收 AC管理设备反馈的至少 1个 AC的连接信息,至少 1个 AC中的每个 AC 的管理区域均覆盖 WTP的地理位置, 连接信息包括静态地址、 广播域地址、 标识信息和 DNS信息中的至少一种。
第二种, AC管理设备根据 WTP的鉴权信息中的网络运营商的信息向 WTP 提供至少 1个 AC的连接信息, 该至少 1个 AC中携带有和 WTP的鉴权信息 所指示的运营商的信息一致的至少 1个 AC的连接信息。 具体来讲, 本步骤包 含但不限于如下子步骤:
1、 AC管理设备查询和 WTP的鉴权信息所指示的网络运营商的信息一致 的 AC;
比如, 一个 WTP的鉴权信息所指示的网络运营商信息是 AA, 若一个 AC 的网络运营商信息是 AA,那么这个 AC和该 WTP的网络运营商的信息就是一 致的; 若另一个 AC的网络运营商信息是 DD, 那么这个 AC和该 WTP的网络 运营商的信息就不一致。
2、 AC管理设备将查找到的至少 1个 AC的连接信息发送给 WTP;
第三种, AC管理设备根据 WTP的地理位置和鉴权信息两者的结合向 WTP 提供至少 1个 AC的连接信息;
提供的至少 1个 AC的连接信息所对应的 AC,其管理区域覆盖 WTP的地 理位置并且和 WTP的鉴权信息所指示的运营商的信息一致的至少 1个 AC的 连接信息。 具体来讲, 本步骤包含但不限于如下子步骤:
1、 AC管理设备在至少 1个 AC中查询管理区域覆盖 WTP的地理位置的 至少 1个 AC,然后在上述查询到的至少 1个 AC中查询和 WTP的鉴权信息所 指示的网络运营商的信息一致的 AC; 或者,先查询和 WTP网络运营商一致的 AC, 再在上述查询到的 AC中查询出管理区域覆盖 WTP的地理位置的至少 1 个 AC;
2、 AC管理设备将查询到的至少 1个 AC的连接信息发送给 WTP;
第三种实现方式不再详述, 具体可参见上述第一种方式和第二种方式。 步骤 505, WTP根据获取到的连接信息与至少 1个 AC建立连接。
WTP在获取到 AC的连接信息之后,由 ACS CONN状态进入 DISC(发现 ) 状态。 WTP根据 AC的连接信息与至少 1个 AC建立连接,并接受 AC的管理。 WTP一般和一个 AC建立连接。
具体来讲, 根据连接信息的不同, 本步骤可以包括如下四种方式中的任意 一种:
第一种, 若连接信息为静态地址, 则 WTP根据 AC的静态地址发现并与 其建立连接;
第二种, 若连接信息为广播域地址, 则 WTP和 AC处于同一广播域中, WTP发现 AC并与其建立;
第三种,若连接信息为标识信息,则 WTP通过动态主机设置协议( Dynamic Host Configuration Protocol, DHCP ) option 43和标识信息查找 AC的地址并与 其建立连接;
第四种, 若连接信息为 DNS信息, 则 WTP通过指定 AC的 DNS地址来 发现 AC并与其建立连接。
步骤 506, WTP向 AC管理设备发送断开连接请求; 在 WTP与一个 AC成功建立连接之后 , WTP向 AC管理设备发送断开连 接请求。
对应地, AC管理设备接收 WTP的断开连接请求,根据断开连接请求生成 断开响应。
步骤 507, AC管理设备将断开响应反馈给 WTP;
步骤 508, WTP接收断开响应, 并与 AC管理设备断开连接;
需要补充说明的是, WTP如果不能成功与 AC建立连接时, 也可以接受 AC管理设备的管理。 具体来讲, 若从 AC管理设备未获取到任何一个 AC的 连接信息, 或者获取到至少 1个 AC的连接信息之后, 无法与任何一个 AC建 立连接时, 则要进行以下步骤 509和步骤 510:
其中, 包括以下两种情况中的任意一种:
第一种, 在步骤 504中, WTP从 AC管理设备未获取到任何一个 AC的 连接信息; 或,
第二种, 在步骤 505中, WTP获取到至少 1个 AC的连接信息之后, 但无 法与任何一个 AC建立连接。
步骤 509, WTP向 AC管理设备发送请求管理的请求;
WTP在上述两种情况中的任一情况出现时,由 ACS CONN状态或者 DISC 状态进入 ORPHAN RUN (孤立)状态, 然后 WTP向 AC管理设备发送请求管 理的请求。
对应地, AC管理设备接收 WTP发送的请求管理的请求; AC管理设备在 接收到 WTP的请求管理的请求后,向 WTP发送针对请求管理的请求的响应信 息, 以便 WTP在接收到 AC管理设备针对请求管理的请求的响应信息后, 接 受 AC管理设备的管理;
步骤 510, WTP在接收到 AC管理设备针对请求管理的请求的响应信息后, 接受 AC管理设备的管理;
步骤 509和步骤 510可以在步骤 504之后执行,还可以在步骤 505之后执 行。
当 WTP从 AC管理设备未获取到任何 1个 AC的连接信息, 在步骤 504 之后, 执行步骤 509和步骤 510;
当 WTP获取到至少 1个 AC的连接信息之后, 但无法与任何一个 AC建 立连接时, 在步骤 505之后, 执行步骤 509和步骤 510。 AC管理设备对 WTP的管理类似于 AC对 WTP的管理, 包括但不限于如 下内容:
1、 AC管理设备通过配置更新 /复位命令完成对 WTP的配置更新 /复位;
2、 AC管理设备和 WTP之间周期性第交互心跳信息, 使 AC管理设备能 够更好地控制 WTP。 心跳信息是指 WTP是否还在线的信息, 若 AC管理设备 接收不到 WTP的心跳信息, 即 WTP 已经不在线, 则 AC管理设备删除这个 WTP, 达到节约资源的目的。 周期性可以是一个预定的时间阈值。
第三, WTP周期性地将自己的地理位置和统计信息上报给 AC管理设备, 以便 AC管理设备根据 WTP的地理位置和统计信息查找它周围符合条件的 AC, 将 AC的连接信息发送给 WTP; WTP在接收到 AC的连接信息之后, 迁移到 DISC状态, 开启发现 AC的步骤。 周期性可以是一个预定的时间阈值。
第四, WTP也可以周期性地重新尝试与 AC建立连接;
第五, AC管理设备可以通过 WTP来控制某个或多个 STA;
由于一个 WTP可以管理多个 STA,当在多个 STA中,某几个或某一个 STA 会特别地占用资源, 或是某几个或某一个不在工作的 STA。 WTP 可以通过信 道测量、 干扰调度、 负载均衡, 和 /或, 控制 STA接入, 由于 AC管理设备控 制着 WTP, 那么 AC管理设备也可以间接地控制 STA, 则 AC管理设备可以把 某几个或某一个特别占用资源 STA调控到连接个数比较少的 WTP上,或是, AC 管理设备可以断开某几个或某一个不在工作的 STA与 WTP的连接。
综上所述, 本发明实施例提供的 WTP接入方法, 通过唯一的网络地址与 AC管理设备建立连接, AC管理设备用于管理至少 1 个接入控制器 AC; 从 AC管理设备获取至少 1个 AC的连接信息;根据获取到的至连接信息与至少 1 个 AC建立连接; 解决了在目前技术下, WTP获取与 AC相关的先验信息和初 始化条件是较为困难的问题; 达到了 WTP通过 AC管理设备就能够发现 AC 并且和 AC建立连接的效果。
另夕卜,通过步骤 509和步骤 510, 可以使得当 WTP无法与任何一个 AC建 立连接的情况下, 还能接受 AC管理设备的管理的效果。
再者, 通过步骤 503和步骤 504, AC管理设备可以通过 WTP的地理位置 查找到 WTP所处位置的 AC信息, 还可以通过 WTP的鉴权信息所指示的网 络运营商的信息查找网络运营商信息一致的 AC,还可以通过 WTP的地理位置 和鉴权信息相结合的方式查找 AC,使得 AC管理设备向 WTP提供的 AC的连 接信息更加准确, 减少了不必要的信息传输, 达到了节省网络资源的效果。 由 于 WTP接收到的是更加准确的 AC连接信息, 减少了向 AC发送连接请求的 次数, 减少了网络资源消耗。 请参考如 6, 其示出了本发明另一个实施例提供的 WTP接入方法的方法 流程图。 本实施例主要以该 WTP接入方法应用于图 2所示实施环境, 且 WTP 从 AC管理设备获取至少 1个 AC的连接信息和管理区域来举例说明。该 WTP 接入方法, 包括:
