具体实施方式
为使本发明实施例的目的、 技术方案和优点更加清楚, 下面将结合本发 明实施例中的附图, 对本发明实施例中的技术方案进行清楚、 完整地描述, 显然, 所描述的实施例是本发明一部分实施例, 而不是全部的实施例。 基于 本发明中的实施例, 本领域普通技术人员在没有作出创造性劳动前提下所获 得的所有其他实施例, 都属于本发明保护的范围。 需要说明的是, 图 1为本发明隧道处理方法的一种现有应用场景, 如图
1所示, 本发明可以应用于如下场景中, 在 STA的无线传输范围内有至少一 个第一 WTP , 且第一 WTP 和 AC 建立有第一 CAPWAP ( Control And Provisioning of Wireless Access Point, CAPWAP) 隧道, 即第一 CAPWAP隧 道为第一 WTP与 AC之间原有的 CAPWAP隧道, STA与第一 WTP通过 802.11 协议通信。在 STA的无线传输范围内还有一个独立的第二 WTP,该第二 WTP 可以是一种自携带的设备 (Bring Your Own Device , BYOD) 。 其中, 第一 WTP可以是 WiFi中可固定的访问接入点 (Access Point, AP) , 与 AC建立 有第一 CAPWAP 隧道, 而第二 WTP 则是一种移动的接入设备, 并没有与 AC建立第一 CAPWAP隧道。 所以, 第二 WTP所采用的无线信道资源不受 控, 第二 WTP对资源的利用可能会严重干扰 STA或第一 WTP的通信。
图 2为本发明隧道处理方法实施例的流程图, 如图 2所示, 本实施例的 方法可以包括:
S101、 STA与第一 WTP建立第二 CAPWAP隧道。
需要说明的是,第一 WTP与 AC之间通常采用的通信协议为控制无线接 入点协议, 该协议是建立在用户数据包协议 (User Datagram Protocol, UDP) 之上的应用层协议, 它的核心思想是在 AC和第一 WTP之间建立一条隧道, 记作第一 CAPWAP隧道,将控制报文和用户数据报文承载在隧道内,便于集 中管理和保护用户数据。 其中, CAPWAP隧道分为控制隧道和数据隧道, 控 制隧道传送 CAPWAP控制报文, 而数据隧道传送数据报文。
举例说明, STA与第一 WTP建立第二 CAPWAP隧道可以是第一 WTP 或 AC控制建立的, 如由第一 WTP控制建立该第二 CAPWAP隧道, 第一 WTP接收 STA的 CAPWAP隧道建立请求, 根据该请求与 STA之间建立第 二 CAPWAP隧道; 或者, 由 AC控制建立该第二 CAPWAP隧道, 第一 WTP 接收到 STA发送的 CAPWAP隧道建立请求后, 将该 CAPWAP隧道建立请 求转发给 AC, 使得 AC根据该 CAPWAP隧道建立请求控制 WTP与 STA建 立第二 CAPWAP隧道。
进一步地, 在 STA和第一 WTP建立第二 CAPWAP隧道, STA到第一 WTP可以通过 CAPWAP消息携带数据报文或者控制报文, 报文的格式可以 根据 CAPWAP报文原有格式微调形成, 第一 WTP和 AC之间传输的控制消 息和数据消息和现有标准保持基本不变, 其中, 第一 CAPWAP 隧道为第一 WTP与 AC之间原有的 CAPWAP隧道。
5102、 STA 接收第二 WTP 发送的发现请求消息, 发现请求消息包含 CAPWAP隧道建立请求。
5103、 STA 基于 CAPWAP 隧道建立请求确定未与第二 WTP 建立 CAPWAP隧道时, 根据 CAPWAP隧道建立请求内容和 STA的最大接入能力 中的至少一个确定与第二 WTP建立第三 CAPWAP隧道。
进一步地, STA在接收到发现请求消息并确定该发现请求消息中包含有 CAPWAP隧道建立请求时则可以确定该第二 WTP 尚未与该 STA建立第三 CAPWAP隧道,则可以根据 CAPWAP隧道建立请求内容和 STA的最大接入 能力中的至少一个确定与第二 WTP建立第三 CAPWAP隧道。
需要说明的是, STA接收到第二 WTP发送的发现请求消息后可以充当 第二 WTP的 AC, 即可以通过内置的虚拟 AC功能实现与第二 WTP建立第 三 CAPWAP隧道。其中,内置的虚拟 AC功能可以是根据 AC发送的 CAPWAP 消息设定的等。

以使得 AC 通过第一 CAPWAP 隧道、 第二 CAPWAP 隧道以及第三 CAPWAP隧道调整第二 WTP的资源配置,其中,第一 CAPWAP隧道为第一 WTP与 AC之间原有的 CAPWAP隧道。
进一步地, 第二 WTP可以发送发现请求消息, 如果 STA接收到该第二 WTP并返回响应, 则 STA可以充当第二 WTP的 AC; 即 AC可以通过 STA, 即第一 CAPWAP隧道、 第二 CAPWAP隧道和第三 CAPWAP隧道管理第二 WTP, 如对第二 WTP干扰和资源等信息进行管理。 对该第二 WTP进行管控 和调整。 其中, STA可以是多模设备或者多网卡设备等。
进一步地,第三 CAPWAP隧道中传输的 CAPWAP消息携带的 CAPWAP 报文可以与现有的 CAPWAP报文格式一致, 也可以在现有 CAPWAP协议中 定义的 CAPWAP报文进行增添和修改,如增加协议包的报头内容 110对应该 CAPWAP隧道建立请求, 或者在协议包的身份标识号码(ID, Identity)域写 入号码 4对应该 CAPWAP隧道建立请求等,此处仅以此举例说明,其他的通 过该第一 CAPWAP隧道与第二 CAPWAP隧道的消息均可以以此方式对应消 息的内容或策略, 且以其他方式定义的传输于第一 CAPWAP 隧道与第二 CAPWAP隧道的消息均在保护范围之内。

进一步地, 第三 CAPWAP隧道建立的通知中可以携带着第三 CAPWAP 隧道信息, 如 STA的无线范围内可能有多个第二 WTP, 该第三 CAPWAP隧 道携带着第二 WTP的 MAC地址或者按照建立时间进行编号的号码, 以使得 AC根据该隧道信息确定哪一条第三 CAPWAP隧道是对应哪一个第二 WTP 的。
举例来说, 第一条建立的第三 CAPWAP隧道对应第二 WTP1 , 第二条建 立的第三 CAPWAP隧道对应第二 WTP3, 第三条建立的第三 CAPWAP隧道 对应第二 WTP3; 这种情况下, AC可以通过通知中的编码 1 确定返回的消 息、 报文等通过第一条建立的第三 CAPWAP 隧道对应发送到第二 WTP1 ; AC可以通过通知中的编码 2确定返回的消息、 报文等通过第二条建立的第 三 CAPWAP隧道对应发送到第二 WTP3; AC可以通过通知中的编码 3确定 返回的消息、 报文等通过第三条建立的第三 CAPWAP 隧道对应发送到第二 WTP2o 此处只用简单的序列号举例说明, 其他的编码或其他编号指示对应 第三 CAPWAP隧道均在保护范围之内, 不以此做任何限定。
5302、 AC 通过第一 CAPWAP 隧道、 第二 CAPWAP 隧道以及第三 CAPWAP隧道调整第二 WTP的资源配置。
其中, 第一 CAPWAP隧道为第一 WTP与 AC之间原有的 CAPWAP隧 道, 第二 CAPWAP为第一 WTP与 STA建立的 CAPWAP隧道。 需要说明的是, 建立了第一 CAPWAP隧道、 第二 CAPWAP隧道和第二 CAPWAP隧道之后, AC可以根据上报的检测结果对第二 WTP进行资源配 置, 如对第二 WTP 的无线配置进行修改, 包括修改所在信道, 资源调度信 息, 所占用带宽和速率等等参数。

图 5为本发明隧道处理方法再一实施例的流程图, 如图 5所示, 本实施 例的方法可以包括:
在第一 WTP与 AC建立第一 CAPWAP隧道之后, 执行步骤 S401。
S401、 STA与第一 WTP建立第二 CAPWAP隧道。
进一步地, 第二 CAPWAP隧道可以是第一 WTP控制建立的, 也可以是 AC控制建立的。
举例来说, 图 6为本发明提供的隧道建立方法实施例的流程图, 如图 6 所示, 第二 CAPWAP隧道可以是第一 WTP控制建立的。
5501、 STA向第一 WTP发送 CAPWAP隧道建立请求。
5502、 第一 WTP若接收到 STA发送的 CAPWAP隧道建立请求, 则根 据 CAPWAP隧道建立请求内容和第一 WTP的最大接入能力中的至少一个确 定是否建立第一 WTP 与 STA 之间的第二 CAPWAP 隧道, 是则执行步骤 S503; 否, 则执行 S509。
举例来说, 根据 CAPWAP隧道建立请求内容和第一 WTP的最大接入能 力中的至少一个确定是否建立第一 WTP与 STA之间的第二 CAPWAP隧道可 以是: 第一 WTP 根据隧道建立请求的请求条件是否正确确定、 或者根据隧 道建立请求的格式是否正确确定; 或者根据第一 WTP 的能力确定是否准许 建立第二 CAPWAP 隧道确定是否准许建立第二 CAPWAP 隧道; 或者, 当 CAPWAP隧道建立请求内容和第一 WTP的最大接入能力都满足条件时确定 建立第二 CAPWAP隧道。
如, 第一 WTP 根据隧道建立请求的请求条件是否正确确实是否建立 CAPWAP隧道可以是确定该 CAPWAP隧道建立请求的源 STA是否预存在可 建立隧道列表中, 该可建立隧道列表可以预存在第一 WTP中。 如果源 STA 为预存在可建立隧道列表中的 STA则确定准许建立第二 CAPWAP隧道。
如, 第一 WTP 还可以根据隧道建立请求的格式确定是否准许建立第二 CAPWAP 隧道。 该请求可以如上述报文一样预设有特殊的格式, 第一 WTP 如果确定接收到的隧道建立请求符合预设的格式, 则确定准许建立第二 CAPWAP隧道。
或者, 第一 WTP还可以根据第一 WTP 的能力确定是否准许建立第二 CAPWAP隧道。 如, 第一 WTP最大承载建立第二 CAPWAP隧道的能力为建 立五条第二 CAPWAP隧道, 该 STA的隧道建立请求在该第一 WTP只建立了 1至 3条第二 CAPWAP隧道后发送至第一 WTP, 第一 WTP确定第一 WTP 还可以承载多一条的第二 CAPWAP隧道, 则准许建立; 该 STA的隧道建立 请求在该第一 WTP建立了 5条第二 CAPWAP隧道后发送至第一 WTP, 则第 一 WTP能力受限, 第一 WTP不准许建立第一 WTP与该 STA之间的第二 CAPWAP隧道。
需要说明的是, 若准许建立, 可以向 STA 返回建立成功应答, 且执行
S503; 若不准许建立, 可以向 STA返回隧道建立失败通知, 且执行 S512。
S503、 第一 WTP建立与 STA之间的第二 CAPWAP隧道。

进一步地, CAPWAP消息中包含 AC发送的 CAPWAP控制报文或数据 报文, 以对 STA进行资源调度, CAPWAP消息中还包含标识信息, 标示信 息为第一 CAPWAP隧道或第二 CAPWAP隧道建立时根据第一 WTP或 STA 生成。
该标识信息可以为地址信息, 也可以为一预设标识位。 该标识信息用于 使得第一 WTP确定 CAPWAP消息是发送给 STA的消息, 还是发送给第一 WTP的消息。
进一步地, AC也可以接收第一 WTP发送的 CAPWAP消息, 或者, 第 一 WTP转发的 STA发送的 CAPWAP消息, CAPWAP消息均可以包含标识 信息, 以使得该 AC确定 CAPWAP消息的来源, 此处不再展开说明。
需要说明的是, CAPWAP 消息中包含上述实施例中所述描述的 CAPWAP报文, 如控制报文和数据报文, 该 CAPWAP报文的格式和携带内 容可遵照上述实施例中的描述, 在此不再赘述。
5505、 第一 WTP接收 AC发送的 CAPWAP消息。
5506、 第一 WTP根据 CAPWAP消息中标识信息确定 CAPWAP消息是 否为发送给 STA的。
进一步地, 第一 WTP根据 CAPWAP 消息中所包含的标识信息, 确定 CAPWAP消息是否为发送给 STA的消息。 如标识信息为地址信息, 且该地 址信息为有效地址如对应一个 STA的 MAC地址时, 确定该消息为发送给该 MAC地址对应的 STA的消息; 当该地址信息为无效地址, 即对应不到任何 STA的 MAC地址时, 确定该消息为发送给第一 WTP的消息, 比如该消息地 址为 38位 F为有效地址, 不满 38位的 F为无效地址等。 其中, STA的 MAC 地址可以预存在预设列表中, 以查表确定地址信息是否为有效地址, 如在预 设列表中找到相同的 MAC地址则确定为有效地址, 否则为无效地址。
或者, 标识信息为一预设标识位, 若 CAPWAP 消息中所包含的预设标 识位为第一数值, 每个第一数值对应一个 STA, 则第一 WTP 向第一数值对 应的 STA转发 CAPWAP消息; 若 CAPWAP消息中所包含的预设标识位为 第二数值, 第二数值对应第一 WTP, 则第一 WTP处理 CAPWAP消息。 如, 第一数值为 1, 第二数值为 0时, 若该预设标识位为 1, 该 CAPWAP消息为 发送给第一 WTP的; 若该预设标识位为 0, 该 CAPWAP消息为发送给 STA 的; 或者, 第一数值为 0, 第二数值为 1 时, 若预设标识位为 0, 该 CAPWAP消息为发送给第一 WTP的; 若预设标识位为 1, 该 CAPWAP消息 为发送给 STA的。 进一步地, 当第一 WTP预存有多个 STA的对应第一数值时, 第一数值 分别按照 STA接入的顺序对应设置为 01、 10、 11或 1、 2、 3等, 这样可以 便于第一 WTP 与多个 STA 建立有第二 CAPWAP 隧道时, 能够确定该 CAPWAP消息是发送给哪一个 STA的。
第一 WTP根据 CAPWAP消息中标识信息确定 CAPWAP消息是发送给 STA的, 则执行步骤 S507, 若不是则第一 WTP解析该 CAPWAP消息, 并 根据其内容或策略执行相应的操作。
5507、 第一 WTP 向 CAPWAP 消息中标识信息对应的 STA 转发 CAPWAP消息。
5508、 STA接收第一 WTP转发的 CAPWAP消息。
进一步地, STA也可以通过第一 WTP向 AC发送 CAPWAP消息, 即通 过第二 CAPWAP隧道和第一 CAPWAP隧道发送 CAPWAP消息, 这样一 来, STA可以通过 CAPWAP消息与 AC进行交互。
S509、 第一 WTP向 STA发送隧道建立失败通知, 隧道建立失败通知包 含失败原因。
S510、 STA接收第一 WTP发送的隧道建立失败通知, 根据失败原因确 定重新发送 CAPWAP隧道建立请求的时间。
举例来说, STA可以预存一个列表, 该列表中存有数字与失败原因的对 应关系, 该数字可以是编码或序列号, 隧道建立失败通知包含的失败原因可 以是一个编码或序列号, 这样, STA可以通过查询该列表确定隧道建立失败 的原因。
进一步地, 该列表还可以预存该失败原因对应的一个定时器, 以使得 STA在定时器超时后再重新请求建立第二 CAPWAP隧道。 如失败原因为第 一 CAPWAP隧道异常, 则 5秒后重新发送 CAPWAP隧道建立请求等。
或者, 图 7为本发明提供的隧道建立方法另一实施例的流程图, 如图 6 所示, 第二 CAPWAP隧道可以是 AC控制建立的。
5601、 STA通过第一 WTP向 AC发送 CAPWAP隧道建立请求。
进一步地, STA可以向第一 WTP发送 CAPWAP隧道建立请求, 第一
WTP将 CAPWAP隧道建立请求转发给 AC。
5602、 AC 若接收到 STA 发送的 CAPWAP 隧道建立请求, 则根据 CAPWAP隧道建立请求内容和第一 WTP的最大接入能力中的至少一个确定 是否建立第一 WTP与 STA之间的第二 CAPWAP隧道, 是则执行步骤 S603; 否, 则执行 S612。
举例来说, AC可以根据隧道建立请求的请求条件是否正确、还可以根据 隧道建立请求的格式是否正确、或者根据第一 WTP的最大接入能力等的一种 或几种确定是否准许建立第二 CAPWAP 隧道确定是否准许建立第二 CAPWAP隧道。 其确定的方法在上述实施例中已经展开, 在此不再赘述。
S603、 AC向第一 WTP发送通知第二 CAPWAP隧道建立的通知消息。
5604、 第一 WTP接收通知第二 CAPWAP隧道建立的通知消息。
这样一来, 第一 WTP获知已经与 STA建立了第二 CAPWAP隧道。 可以 为后续的转发 STA与 AC之间的 CAPWAP消息做准备。
5605、 第一 WTP建立与 STA之间的第二 CAPWAP隧道, 且向 STA发 送通知第二 CAPWAP隧道建立的通知消息。
5606、 STA接收该通知消息。
需要说明的是, STA 接收到该通知后可以通过第一 WTP 向 AC 发送 CAPWAP消息了, 该 CAPWAP消息中的数据报文或控制报文可以根据上述 实施例给出的报文形式生成, 在此不再赘述。
S607、 AC向第一 WTP发送 CAPWAP消息。
需要说明的是, AC 也可以接收第一 WTP 发送的 CAPWAP 消息, 或 者, 第一 WTP转发的 STA发送的 CAPWAP消息, AC也可以向第一 WTP 发送 CAPWAP消息或者通过第一 WTP向 STA转发 CAPWAP消息。 本实施 例以 AC通过第一 WTP向 STA转发 CAPWAP消息为例进行说明, 但不以此 做任何限定。
进一步地, CAPWAP消息中包含 AC发送的 CAPWAP控制报文或数据 报文, 以对 STA进行资源调度, CAPWAP消息中还包含标识信息, 标示信 息为第一 CAPWAP隧道或第二 CAPWAP隧道建立时根据第一 WTP或 STA 生成。
该标识信息可以为地址信息, 也可以为一预设标识位。 该标识信息用于 使得第一 WTP确定 CAPWAP消息是发送给 STA的消息, 还是发送给第一 WTP的消息。
如, 标识信息为地址信息: 若地址信息为有效地址, 则 AC向第一 WTP 发送 CAPWAP消息, 使得第一 WTP向有效地址对应的 STA转发 CAPWAP 消息; 若标识信息为无效地址, 则 AC向第一 WTP发送 CAPWAP消息, 使 得第一 WTP处理 CAPWAP消息。
标识信息为一预设标识位: 若 CAPWAP 消息中所包含的预设标识位为 第一数值, 每个第一数值对应一个 STA, 则 AC向第一 WTP发送 CAPWAP 消息, 使得第一 WTP 向第一数值对应的 STA 转发 CAPWAP 消息; 若
CAPWAP 消息中所包含的预设标识位为第二数值, 第二数值对应第一
WTP, 则 AC向第一 WTP发送 CAPWAP消息, 使得第一 WTP处理 CAPWAP 消息。
S608、 第一 WTP接收 AC发送的 CAPWAP消息。
S609、 第一 WTP根据 CAPWAP消息中标识信息确定 CAPWAP消息是 否为发送给 STA的。
举例来说。 CAPWAP 消息可以是上述实施例中所述的控制报文和数据 报文, 报文的格式和携带内容可遵照上述实施例中的描述, 在此不再赘述。
若是, 则执行步骤 S610, 若不是则第一 WTP解析该 CAPWAP消息, 并 根据其内容或策略执行相应的操作。
5610、 第一 WTP向 CAPWAP消息中包含的标识信息对应的 STA转发 CAPWAP消息。
5611、 STA接收第一 WTP转发的 CAPWAP消息。
进一步地, STA也可以通过第一 WTP向 AC发送 CAPWAP消息, 即通 过第二 CAPWAP隧道和第一 CAPWAP隧道发送 CAPWAP消息, 这样一 来, STA可以通过 CAPWAP消息与 AC进行交互。
S612、 AC向第一 WTP发送隧道建立失败通知, 第一 WTP向 STA发送 隧道建立失败通知, 隧道建立失败通知包含失败原因。
S613、 STA接收第一 WTP发送的隧道建立失败通知, 根据失败原因确 定重新发送 CAPWAP隧道建立请求的时间。
5402、 第二 WTP发送发现请求消息。
进一步地, 第二 WTP可以低频发送发现请求消息。 如, 第二 WTP低 频、 周期广播发现请求消息, 如信标帧信息, 信标帧信息包含 CAPWAP 隧 道建立请求, 以使得 STA响应 CAPWAP隧道建立请求建立第三 CAPWAP 隧道。
需要说明的是 S402与 S401没有顺序关系。
5403、 STA 接收第二 WTP 发送的发现请求消息, 发现请求消息包含 CAPWAP隧道建立请求。 需要说明的是该 CAPWAP隧道建立请求可以与上述建立第二 CAPWAP 隧道时 STA发送的请求格式或内容相同, 在此不再赘述。
5404、 STA 基于 CAPWAP 隧道建立请求确定未与第二 WTP 建立 CAPWAP隧道时, 根据 CAPWAP隧道建立请求内容和 STA的最大接入能力 中的至少一个确定与第二 WTP建立第三 CAPWAP隧道。 进一步地, CAPWAP隧道建立请求激发了 STA确定是否与第二 WTP建 立了 CAPWAP隧道, 未建立时, STA与第二 WTP建立第三 CAPWAP隧道 的步骤与上述图 6和图 7的步骤相似, 在建立第三 CAPWAP隧道之前, STA 与第二 WTP可以是基于 802.11协议通信的; 第三 CAPWAP隧道可以是由第 一 WTP或 AC控制建立的, 对于第一 WTP来说, STA充当着 AC的角色, 但实际应用中, AC 通过第一 CAPWAP 隧道和第二 CAPWAP 隧道控制 STA, 使得 STA能够充当 AC的角色。 举例来说, 已接入 AC (即已与 AC建立了第一 CAPWAP隧道和第二 CAPWAP隧道) 的 STA, 收到第二 WTP发送的发现请求消息后可确定第二 WTP进入了本端的无线传输范围内。 如果确定第二 WTP未建立 CAPWAP 隧道, 则给第二 WTP分配 IP地址, 并响应第二 WTP的 AC 发现请求 (即 AC discovery request, 已写入现有 CAPWAP隧道命令中)的 CAPWAP隧道连接请 求, 这里对于发现请求的响应可以是 STA转发至第一 WTP, 由第一 WTP控 制完成第三 CAPWAP隧道建立, 也可以是由 STA转发至 AC, 由 AC控制完 成第三 CAPWAP隧道建立。 进一步地, 在转发发现请求消息之前, 由于 STA 的存储和运算能力有 限, STA可以先根据自身能力决定是否为第二 WTP建立隧道, 如 STA可以 根据本端的最大接入第二 WTP量确定是否建立第三 CAPWAP 隧道。 如, STA的最大接入第二 WTP数量为 2个, 而现在 STA未接入任何第二 WTP, 则决定为第二 WTP建立隧道; 如果现在 STA已经接入两个第二 WTP, 则决 定不为第二 WTP建立隧道。
5405、 第二 WTP与 STA建立第三 CAPWAP隧道。
5406、 STA通过第二 CAPWAP隧道和第一 CAPWAP隧道向 AC通知第 三 CAPWAP隧道的建立。
5407、 AC 通过第二 CAPWAP 隧道和第一 CAPWAP 隧道接收第三 CAPWAP隧道建立的通知。
进一步地, 该通知消息携带第三 CAPWAP 隧道的相关信息, 如该通知 可以为第 N隧道建立请求 (如, Tunnel N info announcement request), 这样一 来, AC可以通过该通知确定, 需要进行无线测量的第三 CAPWAP隧道是对 应于哪一个第二 WTP建立的。
需要说明的是, 上述第 N 隧道建立请求可以新写入 CAPWAP 隧道消 息, 可以携带隧道编号等, N为整数。
5408、 STA通过第二 CAPWAP隧道和第一 CAPWAP隧道向 AC发送无 线测量信息请求消息, 无线测量信息请求消息包含第三 CAPWAP 隧道的无 进一步地, 无线测量信息请求消息包含第三 CAPWAP 隧道的无线测量 信息可以包括资源调度信息、 占用带宽速率等, 还可以包含着上述隧道编 号, 以便于 STA、 第一 WTP和 AC识别该信息属于哪个第二 WTP。
5409、 AC通过第二 CAPWAP隧道和第一 CAPWAP隧道接收 STA发送 的无线测量信息请求消息。
5410、 AC通过第一 CAPWAP隧道和第二 CAPWAP隧道向 STA发送无 线配置请求消息, 无线配置请求消息中所包含的配置信息为 AC进行无线测 量后确定的。
举例来说,进行的无线测量在标准中定义的信道链路测量信息的几个典型例 子包括但不限于这些: 某个信道是否有信号如, 是否有雷达信号等; 信道的传 输负载情况; 信道上的干扰信号情况; 信道上的信号强度如测量时间等。
S411、 STA接收 AC通过第一 CAPWAP隧道和第二 CAPWAP隧道发送 的无线配置请求消息。 需要说明的是, 无线配置请求消息可以携带 AC根据所掌握的信息, 对 WTP2进行干扰准入协商控制的指令。 AC给 STA发送无线配置请求消息(如 Wireless Configuration Request) , 使得 STA收到该无线配置请求消息后将消 息转发至第二 WTP, 以使得第二 WTP修改无线配置。
5412、 STA通过第三 CAPWAP隧道向第二 WTP发送无线配置请求消 息。
5413、 第二 WTP 根据无线配置请求消息中所包含的配置信息进行资源 配置。
进一步地, 第二 WTP接收 STA通过第三 CAPWAP隧道发送的无线配置 请求消息, 并根据无线配置请求消息中所包含的配置信息修改所在信道, 资 源调度信息, 所占用带宽和速率等等参数。 这样一来, 本场景通过支持多个第三 CAPWAP隧道管理的 STA, 可以 便捷的对多个第三 CAPWAP 隧道流进行精细化管理, 达到优化网络资源, 减少干扰的作用。 本发明实施例提供的隧道处理方法, STA 与第一 WTP 建立第二 CAPWAP 隧道; 接收第二 WTP 发送的发现请求消息, 发现请求消息包含 CAPWAP隧道建立请求; 基于 CAPWAP隧道建立请求确定未与第二 WTP 建立 CAPWAP隧道时, 根据 CAPWAP隧道建立请求内容和 STA的最大接 入能力中的至少一个确定与第二 WTP建立第三 CAPWAP 隧道; 通过第二 CAPWAP隧道和第一 CAPWAP隧道向 AC通知第三 CAPWAP隧道的建立, 以使得 AC通过第一 CAPWAP隧道、 第二 CAPWAP隧道以及第三 CAPWAP 隧道调整第二 WTP的资源配置, 第一 CAPWAP隧道为第一 WTP与 AC之 间原有的 CAPWAP 隧道。 这样一来, 通过在 WTP 与 STA之间建立第二 CAPWAP隧道, STA与第二 WTP之间建立第三 CAPWAP隧道, 使得 AC 能够通过第一 CAPWAP 隧道、 第二 CAPWAP 隧道控制 STA , 并上述 CAPWAP隧道和第三 CAPWAP隧道控制第二 WTP, 使得第二 WTP根据 AC 的控制进行资源配置, 使得接入网络中各第二 WTP、 STA 均能够合理利用 无线信道, 从而合理管控接入网络的网络资源。
