本发明公开了AP响应方法、发现AP的方法、AP及终端，该AP响应方法包括：AP接收终端发送的探测请求消息，探测请求消息中包含网络漫游指示信息，网络漫游指示信息中包含所述终端的归属地网络指示信息；当所述终端的归属地网络指示信息所指示的网络与所述AP所在网络签有漫游协议时，AP允许向所述终端回复探测响应消息，以使终端发现AP。本发明无需网络中的所有AP都向终端传输探测响应消息，而仅需所在网络与终端所在网络签有同样网络漫游协议的AP回复探测响应消息，由此节省了网络资源；并且避免了终端对没有签署网络漫游协议的AP回复的探测响应消息进行处理，由此减少了终端发现AP的时间，相应提高了终端的网络接入速度。

Description

AP响应方法、 发现 AP的方法、 AP及终端
技术领域 本发明涉及通信技术领域， 特别是涉及 AP ( Access Point, 接入点） 响应方法、 发现 AP的方法、 AP及终端。 背景技术 现有笔记本电脑、 PDA ( Personal Digital Assistant, 个人数字助理）、 手机等终端 均支持 WiFi (Wireless Fidel ity, 无线保真） 技术， 终端通过部署在不同地点的 AP 接入 WiFi网络， AP是一种无线接入设备。 在 WiFi网络中， 每个 AP可以供多个终端 实现接入， 这些终端也称为站点 （Station )。 现有技术中， 每个终端支持某个电信服 务商的网络漫游协议， 因此可以通过同样与该电信服务商签署了网络漫游协议的 AP 接入 WiFi网络， 由于 WiFi网络中包括签署了不同网络漫游协议的 AP， 因此终端需要 选择相应的 AP建立连接， 以实现 WiFi网络接入。 现有技术中， 终端要接入 WiFi网络时， 向网络侧发送探测请求 （Probe Request ) 消 息， 该探测请求消息的 SSID ( Service Set Identifier, 服务集标识） 中的 SSID域 被设置为通配符， 或者指定的网络字符， 当 SSID 域设置为通配符时， 网络中所有接 收到该探测请求消息的 AP 均会向该终端回复探测响应 （Probe Response ) 消息， 当 SSID域设置为指定的网络字符时， 只有与该网络字符对应的网络部署的 AP会回复探 测响应信息。 当有终端签有某个网络漫游协议时， AP在探测响应消息中携带发送该探 测响应消息的 AP 所签署的网络漫游协议的信息， 终端对接收到的探测响应消息中的 信息进行分析， 与该 AP进行进一步的认证关联。 发明人在对现有技术研究的过程中发现， 签有网络漫游协议的终端在选择接入网络的 AP时， 由于网络中所有 AP均需要向终端回复探测响应消息， 因此网络中会存在由所 有 AP 传输的探测响应消息， 造成网络资源的浪费； 且由于终端需要对接收到的多个 探测响应消息进行处理， 因此也增加发现 AP 的时间， 相应降低了终端的网络接入速 度。 发明内容 本发明实施例中提供了 AP响应方法、 发现 AP的方法、 AP及终端， 以解决现有技术中 终端接入网络的过程中浪费网络资源， 且接入速度不高的问题。 为了解决上述技术问题， 本发明实施例公开了如下技术方案： 一种 AP响应方法， 所述方法包括：
AP 接收终端发送的探测请求消息， 所述探测请求消息中包含网络漫游指示信息， 所述网 络漫游指示信息中包含所述终端的归属地网络指示信息； 当所述终端的归属地网络指示信息所指示的网络与所述 AP所在网络签有漫游协议时， 所 述 AP允许向所述终端回复探测响应消息。 一种发现 AP的方法， 所述方法包括： 终端发送探测请求消息， 所述探测请求消息中包含网络漫游指示信息， 所述网络漫游指示 信息中包含所述终端的归属地网络指示信息； 接收 AP返回的探测响应消息，所述 AP所在网络与所述终端的归属地网络指示信息所指示 的网络签有漫游协议； 接入返回所述探测响应消息的 AP。 一种接入点 AP， 所述 AP包括： 接收单元， 用于接收终端发送的探测请求消息， 所述探测请求消息中包含网络漫游指示 信息， 所述网络漫游指示信息中包含所述终端的归属地网络指示信息； 响应单元， 用于当所述终端的归属地网络指示信息所指示的网络与所述 AP所在网络签有 漫游协议时， 允许向所述终端回复探测响应消息。 一种终端， 所述终端包括： 发送单元， 用于发送探测请求消息， 所述探测请求消息中包含网络漫游指示信息， 所述网 络漫游指示信息中包含所述终端的归属地网络指示信息； 接收单元， 用于接收 AP返回的探测响应消息， 所述 AP所在网络与所述终端的归属地网络 指示信息所指示的网络签有漫游协议。 本发明实施例中， AP接收终端发送的探测请求消息， 该探测请求消息中包含网络漫游 指示信息， 网络漫游指示信息中包含终端的归属地网络指示信息， 当终端的归属地网 络指示信息所指示的网络与 AP所在网络签有漫游协议时， AP允许向终端回复探测响 应消息， 以便终端对 AP进行发现。 由于本发明实施例中终端在发现 AP时， 在探测请 求消息的网络漫游指示信息中携带了终端的归属地网络指示信息， 因此无需网络中的 所有 AP 都向终端传输探测响应消息， 而仅需所在网络与终端所在网络签有同样网络 漫游协议的 AP 回复探测响应消息， 由此节省了网络资源； 并且避免了终端对没有签 署网络漫游协议的 AP回复的探测响应消息进行处理，由此减少了终端发现 AP的时间， 相应提高了终端的网络接入速度。 附图说明 为了更清楚地说明本发明实施例或现有技术中的技术方案， 下面将对实施例或现有技 术描述中所需要使用的附图作简单地介绍， 显而易见地， 对于本领域普通技术人员而 言， 在不付出创造性劳动性的前提下， 还可以根据这些附图获得其他的附图。 图 1为本发明 AP响应方法的第一实施例流程图； 图 2为本发明 AP响应方法的第二实施例流程图； 图 3为本发明 AP响应方法的第三实施例流程图； 图 4为本发明 AP响应方法的第三实施例流程图； 图 5为本发明发现 AP的方法的实施例流程图； 图 6为本发明 AP的实施例框图； 图 7为本发明终端的实施例框图。 具体实施方式 本发明如下实施例提供了 AP响应方法、 发现 AP的方法、 AP及终端。 为了使本技术领域的人员更好地理解本发明实施例中的技术方案， 并使本发明实施例 的上述目的、 特征和优点能够更加明显易懂， 下面结合附图对本发明实施例中技术方 案作进一步详细的说明。 参见图 1， 为本发明 AP响应方法的第一实施例流程图: 步骤 101 : AP接收终端发送的探测请求消息， 该探测请求消息中包含网络漫游指示信息， 网络漫游指示信息中包含终端的归属地网络指示信息。 其中， 终端可以在探测请求消息中包含 SSID, 所述 SSID中包含所述终端的归属地网络的 标识信息； 或者， 也可以在探测请求消息中包含 SSID, 所述 SSID中包含所述终端的归 属地网络的标识信息和漫游指示； 或者， 也可以在探测请求消息中包含漫游网络信息元 素， 所述漫游网络信息元素中包含所述终端的归属地网络的标识信息。 步骤 102: 当终端的归属地网络指示信息所指示的网络与 AP所在网络签有漫游协议时， 该 AP允许向该终端回复探测响应消息。
"漫游"是用户离开其签约的归属地网络而进入其它网络时仍可以享受通信服务的特性， 本实施例中的漫游协议指网络服务提供商之间达成的协议， 当终端离开归属地网络进入 其它网络时， 如果其它网络与该归属地网络签有漫游协议， 则可以由其它网络为该终 端提供服务。 其中， 当步骤 101 中接收的探测请求消息中包含 SSID, 且所述 SSID中包含所述终端的 归属地网络的标识信息时， 所述 AP读取所述探测请求消息中的 SSID, 获取所述 SSID 中的所述终端的归属地网络的标识信息， 当根据所述标识信息确定所述 AP 不属于所 述终端的归属地网络时， 触发比较所述标识信息指示的网络与所述 AP 所在的网络是 否签有漫游协议， 当所述标识信息指示的网络与所述 AP所在的网络签有漫游协议时， 所述 AP允许向所述终端发送探测响应消息； 其中， 当步骤 101中接收的探测请求消息中包含 SSID, 且所述 SSID中包含所述终端的 归属地网络的标识信息和漫游指示时， 所述 AP读取所述探测请求消息中的 SSID, 获 取所述 SSID 中的所述终端的归属地网络的标识信息和漫游指示， 根据获取到的所述 漫游指示触发比较所述标识信息指示的网络与所述 AP所在的网络是否签有漫游协议， 当所述标识信息指示的网络与所述 AP所在的网络签有漫游协议时， 所述 AP允许向所 述终端发送探测响应消息； 其中 ， 当步骤 101中接收的探测请求消息中包含漫游网络信息元素， 所述漫游网络信 息元素中包含所述终端的归属地网络的标识信息时， 所述 AP 读取所述探测请求消息 中的网络信息元素， 获取所述网络信息元素中的所述终端的归属地网络的标识信息， 比较所述标识信息指示的网络与所述 AP 所在的网络是否签有漫游协议， 当所述标识 信息指示的网络与所述 AP所在的网络签有漫游协议时， 所述 AP允许向所述终端发送 探测响应消息。 需要说明的是， AP允许向所述终端发送探测响应消息之后， AP可以直接向所述终端回 复探测响应消息； 或者， AP也可以在满足其它预设条件后， 再向所述终端回复探测响应 消息。 由上述实施例可见， 终端在发现 AP 时， 在探测请求消息的网络漫游指示信息中携带 了终端的归属地网络指示信息， 因此无需网络中的所有 AP 都向终端传输探测响应消 息， 而仅需与终端所在网络签有同样网络漫游协议的网络中的 AP回复探测响应消息， 由此节省了网络资源； 并且避免了终端对没有签署网络漫游协议的 AP 回复的探测响 应消息进行处理， 由此减少了终端发现 AP的时间， 相应提高了终端的网络接入速度。 参见图 2， 为本发明 AP响应方法的第二实施例流程图， 该实施例示出了根据探测请求 消息的 SSID中包含的终端的归属地网络的标识信息进行 AP响应的过程： 步骤 201 : AP接收终端发送的探测请求消息， 该探测请求消息中包含 SSID, 该 SSID中 包含终端的归属地网络的标识信息。 其中， SSID是现有探测请求消息中包含的信息元素， 现有机制中 SSID的 SSID域中可 包含的信息包括： 指定的网络名称 （如***部署的 wifi 网络可以写入 " China Unicom"), 指定网络的 ID (如***部署的 wifi 网络可以写入 " 46001 ")， 某个 wifi网络的名称 （如肯德基部署的热点可以命名为 "KFC")， 通配符 （用 " *"表示任 意网络）。 本实施例中， SSID的 SSID域中包含的终端的归属地网络的标识信息可以是指定网络的名 称， 或者指定网络的 ID， SSID中除了包含 SSID域， 还包含 SSID名称和 SSID长度。 如下表 1所示， 为探测请求消息中的一种 SSID的格式示意图， 其中 SSID域中包含的标 识信息是终端的归属地网络的字符信息： 表 1
Figure imgf000007_0001
如上表 1 中， 在 SSID域中设置终端的归属地网络的字符名称， 即该字符名称表示终 端所在的网络， 例如， 如果终端的归属地网络为***的网络， 则 SSID 域设置为 上表 1所示的 " China UniCom"。 该设置在本实施例中进一步用于后续判断在终端的归 属地网络与 AP所在网络签有漫游协议时， AP允许向所述终端回复探测响应消息。 如下表 2所示， 为探测请求消息中的另一种 SSID的格式示意图， 其中 SSID域中承载的 标识信息是终端的归属地网络的 ID信息： 表 2
Figure imgf000008_0001
如上表 2中， 在 SSID域中设置终端的归属地网络的网络 ID， 即该网络 ID表示终端所 在的网络， 例如， 如果终端的归属地网络为***的网络， 则 SSID域设置为上表 2 所示的 " 46001 "。 该设置在本实施例中进一步用于后续判断终端的归属地网络与 AP所 在网络签有漫游协议时， AP允许向所述终端回复探测响应消息。 该网络 ID 的定义使用 IMSI ( International Mobi le Subscriber Identification Number , 国际移动用户 标识码） 中的定义方式， 共包含 5位数字， 即该协议 ID中包括 MCC (Mobi le Country Code , 移动国家号码）、 MNC ( Mobi le Network Code , 移动网络号码） 和随机值， 其 中， MCC标识终端所属的国家， 由三位数字组成 （例如， 中国为 460 )， 丽 C标识终端 所归属的移动网 PLMN ( Publ ic Land Mobi le Network, 公共陆地移动网络）， 由两位 数字组成 （例如， ***的数字共用蜂窝移动通信网为 01 )。 步骤 202: 读取探测请求消息中的 SSID, 获取 SSID中的终端的归属地网络的标识信息。 结合上表 1可知， 网络中的所有 AP都会接收到终端发送的探测请求消息， 对于每一 个 AP， 其会读取探测请求消息中的 SSID域上承载的字符信息， 即读取表 1中 SSID域 上承载的 " China Unicom", 根据该字符 " China Unicom" 可知终端的归属地网络为 ***的网络。 结合上表 2可知， 网络中的所有 AP都会接收到终端发送的探测请求消息， 对于每一 个 AP， 其会读取探测请求消息中的 SSID域上承载的网络 ID， 即读取表 2中 SSID域 上承载的 " 46001 "， 根据该 ID " 46001 "可知终端的归属地网络为***的网络。 步骤 203: 根据标识信息确定 AP是否属于终端的归属地网络， 若是， 则执行步骤 205; 否 则， 执行步骤 204。 当 AP获取到终端的归属地网络的标识信息后， 需要判断 AP所在的网络是否与终端的归 属地网络为同一网络。 例如， 当终端的归属地网络为***的网络时， 则 AP需要判断 其是否也属于***的网络。 步骤 204: 比较标识信息指示的网络与 AP所在的网络是否签有漫游协议， 若是， 则执行 步骤 205 ; 否则， 执行步骤 206。 当 AP不属于所述终端的归属地网络时，进一步比较获取到的标识信息指示的网络与 AP所 在的网络是否签有漫游协议。 本实施例中， 每个 AP内保存了与该 AP所在网络签有网络漫游协议的网络的信息， 例如， AP所在网络为网络 A， 与网络 A签有网络漫游协议的网络包括网络 B和网络 C， 则 AP保 存上述网络 B和网络 C的标识信息， 因此当获取到终端的归属地网络的标识信息后， 可以 在上述保存的网络 B和网络 C的标识信息中查找所述终端的归属地网络的标识信息，如果 查找到， 则说明终端所在网络与 AP所在网络签有漫游协议， 如果未查找到， 则说明终端 所在网络与 AP所在网络未签有漫游协议。 步骤 205 : AP允许向终端发送探测响应消息， 结束当前流程。 当标识信息指示的网络与所述 AP所在的网络签有漫游协议时，允许所述 AP向所述终端发 送探测响应消息， 以使接收到该探测响应消息的终端可以对该 AP进行发现。 需要说明的是， AP允许向所述终端发送探测响应消息之后， AP可以直接向所述终端回 复探测响应消息； 或者， AP也可以在满足其它预设条件后， 再向所述终端回复探测响应 消息。 步骤 206 : AP禁止向终端回复探测响应消息， 结束当前流程。 当标识信息指示的网络与 AP所在的网络没有签有漫游协议时， 该 AP不会向终端回复探 测响应消息， 由于终端不会接收到该 AP发送的探测响应消息， 因此避免了终端对没有 签署网络漫游协议的 AP回复的探测响应消息进行处理， 提高了终端发现 AP的速度。 由上述实施例可见， 由于终端在发现 AP时， 在探测请求消息的 SSID中包含了终端的 归属地网络的标识信息， 因此无需网络中的所有 AP都向终端传输探测响应消息， 而可 以保证与终端所在网络签署了同样网络漫游协议的网络中的 AP 回复探测响应消息， 由此节省了网络资源； 并且避免了终端对没有签署网络漫游协议的 AP回复的探测响应消 息进行处理， 由此减少了终端发现 AP的时间， 相应提高了终端的网络接入速度。 参见图 3， 为本发明 AP响应方法的第三实施例流程图， 该实施例示出了根据探测请求 消息中的 SSID中包含的终端的归属地网络的标识信息和漫游指示进行 AP响应的过程： 步骤 301 : AP接收终端发送的探测请求消息， 该探测请求消息中包含 SSID, 该 SSID中 包含终端的归属地网络的标识信息和漫游指示。 本实施例中， SSID的 SSID域中包含的终端的归属地网络的标识信息可以是指定网络的名 称， 或者指定网络的 ID， SSID中除了包含 SSID域， 还包含 SSID名称和 SSID长度。 如下表 3所示， 为探测请求消息中的一种 SSID的格式示意图， 其中 SSID域中包含的标 识信息以字符信息为例进行说明： 表 3
Figure imgf000010_0001
如上表 3 中， 在 SSID域中设置终端的归属地网络的字符名称和漫游指示， 即该字符 名称表示终端所在的网络， 例如， 如果终端的归属地网络为***的网络， 则 SSID 域设置为上表 3所示的 " China Unicom"; " *: " 作为一个漫游指示， 用于触发后续判 断终端的归属地网络与 AP所在网络签有漫游协议时，所述 AP允许向所述终端回复探测响 应消息。 即与图 2所示实施例的不同在于， 由于本实施例中设置了漫游指示， 因此 AP 不必再判别自身是否位于终端所在的归属地网络中。 另外， 需要说明的是， 上表 3中 的标识信息以字符信息为例进行说明， 实际应用中该标识信息也可以为网络 ID， 在此 不再赘述。 步骤 302 : 读取探测请求消息中的 SSID, 获取 SSID中的终端的归属地网络的标识信息和 漫游指示。 结合上表 3可知， 网络中的所有 AP都会接收到终端发送的探测请求消息， 对于每一 个 AP， 其会读取探测请求消息中的新增信息域上承载的字符信息和漫游指示， 即读取 表 3中 SSID域上承载的 " * : China Unicom", 根据该字符 " China Unicom" 可知终端 的归属地网络为***的网络， 并且根据 " * : " 触发执行步骤 303的判断终端的归 属地网络与 AP所在网络是否签有漫游协议。 步骤 303 : 根据获取到的漫游指示触发比较标识信息指示的网络与 AP所在的网络是否签 有漫游协议， 若是， 则执行步骤 304 ; 否则， 执行步骤 305。 本实施例中， 每个 AP内保存了与该 AP所在网络签有网络漫游协议的网络的信息， 例如， AP所在网络为网络 A， 与网络 A签有网络漫游协议的网络包括网络 B和网络 C， 则 AP保 存上述网络 B和网络 C的标识信息， 因此当获取到终端的归属地网络的标识信息后， 可以 在上述保存的网络 B和网络 C的标识信息中查找所述终端的归属地网络的标识信息，如果 查找到， 则说明终端所在网络与 AP所在网络签有漫游协议， 如果未查找到， 则说明终端 所在网络与 AP所在网络未签有漫游协议。 步骤 304: AP允许向终端发送探测响应消息， 结束当前流程。 当标识信息指示的网络与所述 AP所在的网络签有漫游协议时，允许所述 AP向所述终端发 送探测响应消息， 以使接收到该探测响应消息的终端可以对该 AP进行发现。 需要说明的是， AP允许向所述终端发送探测响应消息之后， AP可以直接向所述终端回 复探测响应消息； 或者， AP也可以在满足其它预设条件后， 再向所述终端回复探测响应 消息。 步骤 305 : AP禁止向终端回复探测响应消息， 结束当前流程。 当标识信息指示的网络与 AP所在的网络没有签有漫游协议时， 该 AP不会向终端回复探 测响应消息， 由于终端不会接收到该 AP发送的探测响应消息， 因此避免了终端对没有 签署网络漫游协议的 AP回复的探测响应消息进行处理， 提高了终端发现 AP的速度。 由上述实施例可见， 由于终端在发现 AP时， 在探测请求消息的 SSID中包含了终端的 归属地网络的标识信息和漫游指示， 因此无需网络中的所有 AP都向终端传输探测响应 消息， 而可以保证与终端所在网络签署了同样网络漫游协议的网络中的 AP 回复探测 响应消息， 由此节省了网络资源； 并且避免了终端对没有签署网络漫游协议的 AP 回复 的探测响应消息进行处理， 由此减少了终端发现 AP的时间， 相应提高了终端的网络接入 速度。 参见图 4， 为本发明 AP响应方法的第四实施例流程图， 该实施例示出了根据探测请求 消息中新增漫游网络信息元素中包含的终端的归属地网络的标识信息进行 AP 响应的过 程： 步骤 401 : AP接收终端发送的探测请求消息， 该探测请求消息中包含漫游网络信息元 素， 漫游网络信息元素中包含终端的归属地网络的标识信息。 前述图 2和图 3示出的实施例中的探测请求消息在 SSID中包含终端的归属地网络的 标识信息， 本实施例中在探测请求消息中新增加一个漫游网络信息元素， 并在该漫游 网络信息元素中包含终端的归属地网络的标识信息。 本实施例中， 新增的漫游网络信息元素的元素域承载的终端的归属地网络的标识信息可 以是指定网络的名称， 或者指定网络的 ID， 漫游网络信息元素中除了包含元素域， 还包 含元素名称和元素长度。 如下表 4所示， 为探测请求消息中的一种漫游网络信息元素的格式示意图， 其中漫游网 络信息元素的元素域中包含的标识信息是终端的归属地网络的字符信息： 表 4
Figure imgf000012_0001
如上表 4 中， 在漫游网络信息元素的元素域中设置终端的归属地网络的字符名称， 即 该字符名称表示终端所在的网络， 例如， 如果终端的归属地网络为***的网络， 则漫游网络信息元素的元素域设置为上表 4所示的 " China UniCom"。 该设置在本实施 例中进一步用于后续判断终端的归属地网络与 AP所在网络签有漫游协议时， 所述 AP允 许向所述终端回复探测响应消息。 如下表 5所示， 为探测请求消息中的另一种漫游网络信息元素的格式示意图， 其中漫游 网络信息元素的元素域中包含的标识信息是终端的归属地网络的 ID信息： 表 5

如上表 5中， 在漫游网络信息元素的元素域中设置终端的归属地网络的网络 ID， 即该 网络 ID 表示终端所在的网络， 例如， 如果终端的归属地网络为***的网络， 则 漫游网络信息元素的元素域设置为上表 5 所示的 " 46001 "。 该设置在本实施例中进一 步用于后续判断终端的归属地网络与 AP所在网络签有漫游协议时， 所述 AP允许向所述 终端回复探测响应消息。 步骤 402 : 读取探测请求消息中的网络信息元素， 获取网络信息元素中的终端的归属地网 络的标识信息。 结合上表 4可知， 网络中的所有 AP都会接收到终端发送的探测请求消息， 对于每一 个 AP， 其会读取探测请求消息中的漫游网络信息元素的元素域上承载的字符信息， 即 读取表 4中漫游网络信息元素的元素域上承载的 " China Unicom", 根据该字符 " China Unicom"可知终端的归属地网络为***的网络。 结合上表 5可知， 网络中的所有 AP都会接收到终端发送的探测请求消息， 对于每一 个 AP， 其会读取探测请求消息中的漫游网络信息元素的元素域上承载的网络 ID， 即读 取表 5中漫游网络信息元素的元素域上承载的 " 46001 "， 根据该 ID " 46001 "可知终端 的归属地网络为***的网络。 步骤 403 : 比较标识信息指示的网络与 AP所在的网络是否签有漫游协议， 若是， 则执行 步骤 404; 否则， 执行步骤 405。 本实施例中， 每个 AP内保存了与该 AP所在网络签有网络漫游协议的网络的信息， 例如， AP所在网络为网络 A， 与网络 A签有网络漫游协议的网络包括网络 B和网络 C， 则 AP保 存上述网络 B和网络 C的标识信息， 因此当获取到终端的归属地网络的标识信息后， 可以 在上述保存的网络 B和网络 C的标识信息中查找所述终端的归属地网络的标识信息，如果 查找到， 则说明终端所在网络与 AP所在网络签有漫游协议， 如果未查找到， 则说明终端 所在网络与 AP所在网络未签有漫游协议。 步骤 404: AP允许向终端发送探测响应消息， 结束当前流程。 当标识信息指示的网络与所述 AP所在的网络签有漫游协议时，允许所述 AP向所述终端发 送探测响应消息， 以使接收到该探测响应消息的终端可以对该 AP进行发现。 需要说明的是， AP允许向所述终端发送探测响应消息之后， AP可以直接向所述终端回 复探测响应消息； 或者， AP也可以在满足其它预设条件后， 再向所述终端回复探测响应 消息。 步骤 405 : AP禁止向终端回复探测响应消息， 结束当前流程。 当标识信息指示的网络与 AP所在的网络没有签有漫游协议时， 该 AP不会向终端回复探 测响应消息， 由于终端不会接收到该 AP发送的探测响应消息， 因此避免了终端对没有 签署网络漫游协议的 AP回复的探测响应消息进行处理， 提高了终端发现 AP的速度。 由上述实施例可见， 由于终端在发现 AP时， 在探测请求消息新增的漫游网络信息元素 中包含了终端的归属地网络的标识信息， 因此无需网络中的所有 AP都向终端传输探测 响应消息， 而可以保证与终端所在网络签署了同样网络漫游协议的网络中的 AP 回复 探测响应消息， 由此节省了网络资源； 并且避免了终端对没有签署网络漫游协议的 AP 回复的探测响应消息进行处理， 由此减少了终端发现 AP的时间， 相应提高了终端的网络 接入速度。 与前述 AP响应方法的实施例相对应，本发明还提供了发现 AP的方法的实施例。其中， 前述 AP响应实施例从 AP侧描述了 AP根据接收到的探测请求消息， 在 AP所在网络与 终端所在网络签有网络漫游协议时， 才向该终端回复探测响应消息的过程； 而下述发 现 AP 的方法实施例将从终端侧描述终端对回复了探测响应消息的 AP 进行发现的过 程。 参见图 5， 为本发明发现 AP的方法的实施例流程图： 步骤 501 : 终端发送探测请求消息， 探测请求消息中包含网络漫游指示信息， 网络漫游指 示信息中包含终端的归属地网络指示信息。 终端想要对 AP进行发现时， 需要发送探测请求消息。 其中， 终端可以在探测请求消息 中包含 SSID, 所述 SSID中包含所述终端的归属地网络的标识信息； 或者， 也可以在探测 请求消息中包含 SSID, 所述 SSID中包含所述终端的归属地网络的标识信息和漫游指示； 或者， 也可以在探测请求消息中包含漫游网络信息元素， 所述漫游网络信息元素中包含 所述终端的归属地网络的标识信息。 步骤 502 : 接收 AP返回的探测响应消息， 该 AP所在网络与终端的归属地网络指示信息所 指示的网络签有漫游协议。 由上述实施例可见， 终端在发现 AP时， 在探测请求消息的网络漫游指示信息中携带了终 端的归属地网络指示信息， 因此无需网络中的所有 AP都向终端传输探测响应消息， 而仅 需与终端归属地网络签有同样网络漫游协议的网络中的 AP回复探测响应消息， 由此节省 了网络资源； 并且避免了终端对没有签署网络漫游协议的 AP回复的探测响应消息进行处 理， 由此减少了终端发现 AP的时间， 相应提高了终端的网络接入速度。 与本发明 AP响应方法的实施例和发现 AP的方法的实施例相对应， 本发明还分别提供 了执行上述 AP响应方法实施例的 AP的实施例， 以及执行上述发现 AP的方法的实施 例的终端的实施例。 参见图 6， 为本发明 AP的第一实施例框图： 该 AP包括： 接收单元 610和响应单元 620。 接收单元 610，用于接收终端发送的探测请求消息，所述探测请求消息中包含网络漫游指 示信息， 所述网络漫游指示信息中包含所述终端的归属地网络指示信息； 响应单元 620， 用于当所述终端的归属地网络指示信息所指示的网络与所述 AP所在网络 签有漫游协议时， 允许向所述终端回复探测响应消息。 需要说明的是， 在允许向所述终 端回复探测响应消息之后，响应单元 620可以直接向所述终端回复探测响应消息；或者， 响应单元 620也可以在满足其它预设条件后， 再向所述终端回复探测响应消息。 具体的， 所述接收单元 610接收的探测请求消息中包含 SSID, 所述 SSID中包含所述终 端的归属地网络的标识信息； 响应单元 620可以包括 （图 6中未示出）： 第一读取子单元， 用于读取所述探测请求消息中的 SSID， 获取所述 SSID中的所述终 端的归属地网络的标识信息； 第一比较子单元， 用于当根据所述标识信息确定所述 AP 不属于所述终端的归属地网 络时， 触发比较所述标识信息指示的网络与所述 AP所在的网络是否签有漫游协议； 第一响应子单元， 用于当所述标识信息指示的网络与所述 AP 所在的网络签有漫游协 议时， 第一响应子单元允许向所述终端发送探测响应消息。 需要说明的是， 在允许向 所述终端发送探测响应消息之后，第一响应子单元可以直接向所述终端回复探测响应消 息； 或者， 第一响应子单元也可以在满足其它预设条件后， 再向所述终端回复探测响应 消息。 具体的， 所述接收单元 610接收的探测请求消息中包含 SSID, 所述 SSID中包含所述终 端的归属地网络的标识信息和漫游指示； 响应单元 620可以包括 （图 6中未示出）： 第二读取子单元， 用于读取所述探测请求消息中的 SSID， 获取所述 SSID中的所述终 端的归属地网络的标识信息和漫游指示； 第二比较子单元， 用于根据获取到的所述漫游指示触发比较所述标识信息指示的网络 与所述 AP所在的网络是否签有漫游协议； 第二响应子单元， 用于当所述标识信息指示的网络与所述 AP 所在的网络签有漫游协 议时， 第二响应子单元允许向所述终端发送探测响应消息。 需要说明的是， 在允许向 所述终端发送探测响应消息之后，第二响应子单元可以直接向所述终端回复探测响应消 息； 或者， 第二响应子单元也可以在满足其它预设条件后， 再向所述终端回复探测响应 消息。 具体的， 所述接收单元 610接收的探测请求消息中包含漫游网络信息元素， 所述漫游网 络信息元素中包含所述终端的归属地网络的标识信息； 响应单元 620可以包括 （图 6中未示出）： 第三读取子单元， 用于读取所述探测请求消息中的网络信息元素， 获取所述网络信息 元素中的所述终端的归属地网络的标识信息； 第三比较子单元， 用于比较所述标识信息指示的网络与所述 AP 所在的网络是否签有 漫游协议； 第三响应子单元， 用于当所述标识信息指示的网络与所述 AP 所在的网络签有漫游协 议时， 第三响应子单元允许向所述终端发送探测响应消息。 需要说明的是， 在允许发 送探测响应消息之后， 第三响应子单元可以直接向所述终端回复探测响应消息； 或者， 第三响应子单元也可以在满足其它预设条件后， 再向所述终端回复探测响应消息。 参见图 7， 为本发明中终端的实施例框图： 该终端包括： 发送单元 710和接收单元 720。 发送单元 710， 用于发送探测请求消息， 所述探测请求消息中包含网络漫游指示信息， 所 述网络漫游指示信息中包含所述终端的归属地网络指示信息； 其中， 所述发送单元 710发送的探测请求消息中包含 SSID, 所述 SSID中包含所述终端 的归属地网络的标识信息； 或者所述发送单元 710 发送的探测请求消息中包含 SSID, 所述 SSID中包含所述终端的归属地网络的标识信息和漫游指示； 或者所述发送单元 710 发送的探测请求消息中包含漫游网络信息元素， 所述漫游网络信息元素中包含所述终端 的归属地网络的标识信息。 接收单元 720， 用于接收 AP返回的探测响应消息， 所述 AP所在网络与所述终端的归 属地网络指示信息所指示的网络签有漫游协议。 由上述实施例可见， AP接收终端发送的探测请求消息， 该探测请求消息中包含网络漫 游指示信息， 网络漫游指示信息中包含终端的归属地网络指示信息， 当终端的归属地 网络指示信息所指示的网络与 AP所在网络签有漫游协议时， AP允许向终端回复探测 响应消息， 以便终端发现 AP。 由于本发明实施例中终端在发现 AP时， 在探测请求消 息的网络漫游指示信息中携带了终端的归属地网络指示信息， 因此无需网络中的所有 AP都向终端传输探测响应消息，而仅需与终端所在网络签有同样网络漫游协议的网络 中的 AP 回复探测响应消息， 由此节省了网络资源； 并且避免了终端对没有签署网络 漫游协议的 AP回复的探测响应消息进行处理， 由此减少了终端发现 AP的时间， 相应 提高了终端的网络接入速度。 本领域的技术人员可以清楚地了解到本发明实施例中的技术可借助软件加必需的通 用硬件平台的方式来实现。 基于这样的理解， 本发明实施例中的技术方案本质上或者 说对现有技术做出贡献的部分可以以软件产品的形式体现出来， 该计算机软件产品可 以存储在存储介质中， 如 R0M/RAM、 磁碟、 光盘等， 包括若干指令用以使得一台计算 机设备 （可以是个人计算机， 服务器， 或者网络设备等） 执行本发明各个实施例或者 实施例的某些部分所述的方法。 本说明书中的各个实施例均采用递进的方式描述， 各个实施例之间相同相似的部分互 相参见即可， 每个实施例重点说明的都是与其他实施例的不同之处。 尤其， 对于*** 实施例而言， 由于其基本相似于方法实施例， 所以描述的比较简单， 相关之处参见方 法实施例的部分说明即可。 以上所述的本发明实施方式， 并不构成对本发明保护范围的限定。 任何在本发明的原 则之内所作的修改、 等同替换和改进等， 均应包含在本发明的保护范围之内。
