Description

无线连接方法、终端及无线访问接入点、计算机存储介质 技术领域
本发明涉及通信领域中的无线接入技术，尤其涉及一种无线连接方法、终端及无线访问接入点(AP，Wireless Access Point)、计算机存储介质。
背景技术
随着无线局域网(WLAN)的不断普及，Wi-Fi技术已经深入千家万户，用户通过Wi-Fi上网变得便利。为了满足用户需求、节省成本和集群管理，先后出现了AP、接入控制器(AC，Access Controller或Wireless Access Point Controller)、用户端(CPE，Customer Premise Equipment)等设备。一台AC下可以控制几百甚至上千台AP，一台AP下可以接入几十个无线用户(CPE、无线网卡等)，为网络的管理提供了极大的便利。
用户通过保证AP与用户端之间的Wi-Fi配置信息的匹配，来进行Wi-Fi上网，而用户为了保证自己的信息安全，会不定时地修改控制端(AP)的Wi-Fi配置信息(如安全策略，无线名称或密码等)，由于接入的配置信息不再与AP匹配，就会导致之前能接入的合法用户变成非法用户，被无线系统拒绝接入。因此，在修改完AP端的Wi-Fi配置信息之后，无线设备的Wi-Fi芯片会重启，接着发射重新设置后的新热点，于是，之前连接的合法用户就需要重新扫描Wi-Fi热点，并输入密码连接Wi-Fi，使得用户体验很差。

具体实施方式
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。
实施例一
本发明实施例提供一种无线连接方法，为AP侧的无线连接方法，如图1所示，该方法可以包括：
S101、无线配置信息存在更新时，AP检测当前连接的终端的访问状态， 该访问状态包括信任状态。
需要说明的是，本发明实施例中的终端的访问状态是可以通过AP设置的，即在Web UI设置页面进行设置。例如，若与AP连接的当前终端为合法用户，则设置该终端的访问状态为信任状态，除合法用户外的终端，设置其访问状态为非信任状态。
在本发明实施例提供的无线连接方法实现的前提是：AP检测当前连接的终端的访问状态之前，用户已经通过AP设置好了该终端的访问状态。
需要说明的是，终端的访问状态的设置是由用户设置和决定的，也是可以改变的。
可选的，无线配置信息可以为安全策略，无线名称或密码。
可选的，本发明实施例中的AP可以是无线路由器等可以作为无线接入点的设备。
当用户通过AP的Web UI设置页面，进行无线配置信息的更新(修改)时，AP检测当前连接的终端的访问状态。
可选的，终端的访问状态可以包括：信任状态和非信任状态。
例如，AP可以发送检测请求至当前连接的终端。
可选的，本发明实施例中的无线配置信息可以为Wi-Fi配置信息，也可以为其他形式的无线技术的配置信息，本发明实施例不作限制。
需要说明的是，AP与终端之间的数据传输的前提是，AP正在与该终端进行连接，否则不能进行数据的传输，因此，本发明实施例中的与AP进行交互的终端为当前正在与该AP连接着的设备。
可选的，AP检测当前连接的终端的访问状态，如图2所示，可以包括：S201-S206。具体如下：
S201、AP获取终端的媒体访问控制(MAC，Media Access Control)地址，检测终端的MAC地址是否存在于预存的MAC地址列表中。
AP检测与其连接的终端的信任状态时，首先，由于AP与终端正在连接，因此，AP可以获取该终端的MAC地址，该AP通过检测获取的终端的MAC地址是否存在于预存的MAC地址列表中来判断该终端的访问状态。
需要说明的是，在AP的设置界面进行终端的访问状态的设置时，AP就将该终端的MAC地址保存了，并将该终端的MAC地址经过加密算法加密后，形成加密信息，将该加密信息传输在该终端，由该终端保存与自己对应的该加密信息，即终端中预存的加密信息，这样，就通过AP设置好了该终端的访问状态为信任状态。若要设置当前连接的终端的访问状态为非信任状态时，则AP不保存该终端的MAC地址，也不发送加密信息至终端，即终端中未有预存的加密信息。
示例性的，当手机1与无线路由器连接，且要改变无线路由器中的无线密码时，无线路由器向手机1发起检测请求，读取手机1的MAC地址，判断该手机1的MAC地址是否在无线路由器中预存的MAC地址列表中。
S202、MAC地址存在于预存的MAC地址列表中时，AP获取终端中预存的加密信息。
AP获取终端的MAC地址，并检测该终端的MAC地址是否存在于预存的MAC地址列表中之后，若AP中预存的MAC地址列表中有该终端的MAC地址，则该AP获取该终端中预存的加密信息。
需要说明的是，用户在AP的Web UI设置终端的访问状态时，AP将获取的访问状态为信任状态的终端的MAC地址都保存，形成预存的MAC地址列表，由于连接AP的终端的访问状态为信任状态的可以不止一个，因此，AP中保存的MAC地址也可以不止一个。
可以理解的是，AP可以通过校验终端的MAC地址是否与预存的信任终端的MAC地址一致来初步判断终端的访问状态。但是，由于非法终端可 以伪装自己的MAC地址与信任状态的终端的MAC地址一致，因此，最优的方案是AP在判断终端的MAC地址存在于预存的MAC地址列表中时，获取终端中的加密信息。
例如，AP可以发送获取加密信息的请求至终端，终端中若有加密信息，则发送该加密信息至AP。其中，本发明实施例中的加密信息的获取在S201中已进行了说明，此处不再赘述。
S203、AP对加密信息进行解密，检测解密后的加密信息是否与MAC地址一致。
AP获取终端中预存的加密信息之后，该AP通过与加密算法相应的解密算法对加密信息进行解密，然后，该AP检测解密后的加密信息是否与终端的MAC地址一致。
需要说明的是，加密信息是将访问状态为信任状态的终端的MAC地址进行了加密，因此，解密后的加密信息为终端的MAC地址。
可以理解的是，AP将直接获取的终端的MAC地址与预存的MAC地址列表对比后，排除MAC地址不在预存的MAC列表中的非信任状态的终端，然后，通过与终端中的加密信息的对比，去除伪装MAC地址的终端。
S204、解密后的加密信息与MAC地址一致时，AP确定终端的访问状态为信任状态。
AP对加密信息进行解密之后，解密后的加密信息(终端的MAC地址)与终端的MAC地址一致时，该AP检测或确定该终端的访问状态为信任状态。
可以理解的是，AP将直接获取的终端的MAC地址与预存的MAC地址列表对比后，排除MAC地址不在预存的MAC列表中的非信任状态的终端，然后，通过与终端中的加密信息的对比，去除伪装MAC地址的终端，于是，解密后的加密信息与检测的终端的MAC地址一致时，AP就确定了 该终端的访问状态为信任状态，这样，提高了AP验证终端的访问状态的安全性和可靠性。
S205、解密后的加密信息与MAC地址不一致时，AP确定终端的访问状态为非信任状态。
AP对加密信息进行解密之后，解密后的加密信息(终端的MAC地址)与终端的MAC地址不一致时，该AP检测或确定该终端的访问状态为非信任状态。
可以理解的是，AP将直接获取的终端的MAC地址与预存的MAC地址列表对比后，排除MAC地址不在预存的MAC列表中的非信任状态的终端，然后，通过与终端中的加密信息的对比，去除伪装MAC地址的终端。于是，解密后的加密信息与检测的终端的MAC地址不一致时，AP确定了该终端的访问状态为非信任状态，这样，即使有终端伪装了自己的MAC地址，但是，AP还是可以将伪装的终端检测出来，从而提高了AP验证终端的访问状态的安全性和可靠性。
需要说明的是，本发明实施例中的S204和S205为S203之后的可选步骤，根据实际检测情况选择其中一个步骤执行；也就是说，在本发明实施例中，S203之后，可以执行S204，也可以执行S205，例如执行顺序可以根据实际情况而定，本发明实施例不作限制；并且，S204或S205执行完后，本次处理流程就结束了。
S206、MAC地址不存在于预存的MAC地址列表中时，AP检测终端的访问状态为非信任状态。
AP检测终端的MAC地址是否存在于预存的MAC地址列表中之后，若在该AP预存的MAC地址列表中没有终端的MAC地址，则表明该终端的访问状态为非信任状态。
可以理解的是，AP中的预存MAC地址列表中都没有与终端的MAC 地址一致的，表征该终端未被设置为信任状态的终端。
需要说明的是，本发明实施例中的S202-S205和S206为S201之后的可选步骤，根据实际检测情况选择其中一个步骤执行；也就是说，在本发明实施例中，S201之后，可以执行S202-S205，也可以执行S206，例如执行顺序可以根据实际情况而定，本发明实施例不作限制；并且，S202-S205或S206执行完后，本次处理流程就结束了。
可选的，在本发明实施例中，AP判断终端的访问状态为非信任状态的一种方法还可以为：终端的MAC地址存在于预存的MAC地址列表中时，AP获取终端中预存的加密信息，此时，若AP中未获取到该终端中的加密信息，即该终端中没有加密信息时，则AP可以确定该终端的访问状态为非信任状态。
S102、AP检测到终端的访问状态为信任状态时，发送更新后的无线配置信息至终端。
AP检测当前连接的终端的访问状态之后，若该AP检测到该终端的访问状态为信任状态时，该AP发送更新后的无线配置信息至该终端，即该终端获取到了更新后的无线配置信息。
例如，当AP检测到终端的访问状态为信任状态时，由于该AP已经发送后台服务的配置信息至终端，因此，AP可以将更新后的无线配置信息进行封装后通过后台服务发送至终端，以使得该终端可以根据更新后的无线配置信息，来更新终端中的无线配置信息。
需要说明的是，在设置终端的访问状态时，若设置一个终端的访问状态为信任状态，则AP还会将后台服务发送至该终端，并安装。其中，后台服务是指可以接收AP发送的更新后的无线配置信息的相关服务。
示例性的，假设无线路由器的无线密码被改变，当无线路由器检测到手机1的访问状态为信任状态时，无线路由器发送修改后的无线密码给手 机1。

发送更新后的无线配置信息至终端之后，该AP应用更新后的无线配置信息，断开与该终端的当前连接，并根据该更新后的无线配置信息重新连接终端。
需要说明的是，用户在AP的Web UI上修改无线配置信息时，AP的应用层在接收到下发的修改无线配置信息的消息后，先不下发修改无线配置信息的消息到无线芯片中，而是先让AP检测当前连接的终端的访问状态，即S101。在AP发送更新后的无线配置信息至终端后，AP的应用层才将最新的无线配置信息(更新后的无线配置信息)下发到无线芯片，以及，AP应用该无线芯片重启，根据更新后的无线配置信息发射新的无线热点(即AP应用更新后的无线配置信息)，断开与该终端的当前连接，供终端进行自动重新连接。

示例性的，手机2与无线路由器连接着，在用户修改该无线路由器的无线密码的时候，用户不想手机2连接该无线路由器，于是，将手机2的访问状态设置为非信任状态，AP检测到手机2的访问状态时，AP的应用层才将更新的无线配置信息(包括更新后的无线密码)下发到AP的无线芯 片，以及，AP应用该无线芯片重启，根据更新后的无线配置信息发射新的无线热点(即AP应用更新后的无线配置信息)，由于无线密码的改变，手机2与该无线路由器断开连接。
需要说明的是，本发明实施例中的S102-S103和S104为S101之后的可选步骤，根据实际检测情况选择其中一个步骤执行；也就是说，在本发明实施例中，S101之后，可以执行S102-S103，也可以执行S104，例如执行顺序可以根据实际情况而定，本发明实施例不作限制；并且，S102-S103或S104执行完后，本次处理流程就结束了。

S302、终端根据更新后的无线配置信息，断开与AP的当前连接，并与该AP重新进行无线连接。
终端接收AP发送的更新后的无线配置信息之后，该终端可以应用更新后的无线配置信息，断开与AP的当前连接，并发送连接请求至AP，并使 用更新后的无线配置信息与该AP进行无线连接。

S304、终端接收AP发送的加密信息并保存，该加密信息为将MAC地址加密后的字符串。
S305、终端接收AP发送的后台服务的配置信息，并安装该后台服务。
例如，终端的访问状态在被设置为信任状态时，该终端发送自己的MAC地址至该AP，以供该AP检测终端的访问状态时使用，且该AP在接收到上述终端发送的MAC地址后，通过加密算法将终端的MAC进行加密，并将加密后的加密信息(将MAC地址加密后的字符串)发送至终端，成为终端中预存的加密信息，以及终端接收AP发送的后台服务的配置信息，并安装后台服务。

终端的访问状态被设置为非信任状态时，由于AP侧的无线配置信息被改变了，终端中的无线配置信息与AP的更新后的无线配置信息不相匹配，因此，该终端与该AP的当前的无线连接被断开了。
需要说明的是，本发明实施例中的S301-S305与S306为可选的步骤，根据实际检测情况选择其中一个步骤执行；也就是说，在本发明实施例中，根据实际情况的不同，可以执行S301-S305，也可以执行S306，例如执行顺序可以根据实际情况而定，本发明实施例不作限制；并且，S301-S305或S306执行完后，本次处理流程就结束了。

实施例二
本发明实施例提供一种无线连接方法，如图6所示，该方法可以包括：
S401、终端的访问状态在被设置为信任状态，且与AP连接时，该终端发送其MAC地址至该AP。
可选的，本发明实施例中的终端可以为能够进行无线连接的设备，具体可以为移动电话、智能电话、笔记本电脑、数字广播接收器、个人数字助理、平板电脑、便携式多媒体播放器、导航装置等等的移动终端，以及诸如数字TV、台式计算机等等的固定终端。然而，本领域技术人员将理解 的是，除了特别用于移动目的的元件之外，根据本发明的实施方式的构造也能够应用于固定类型的终端。
S402、AP将终端的MAC地址进行加密，并发送加密信息和后台服务的配置信息至终端，该加密信息为将MAC地址加密后的字符串。
可选的，本发明实施例中的AP可以是无线路由器等可以作为无线接入点的设备。
需要说明的是，AP与终端之间的数据传输的前提是，AP正在与该终端进行连接，否则不能进行数据的传输，因此，本发明实施例中的与AP进行交互的终端为当前正在与该AP连接着的设备。
S403、终端保存加密信息，并根据后台服务的配置信息安装该后台服务。
需要说明的是，本发明实施例中的终端的访问状态是可以通过AP设置的，即在Web UI设置页面进行设置。例如，若与AP连接的当前终端为合法用户，则设置该终端的访问状态为信任状态，除合法用户外的终端，设置其访问状态为非信任状态。
在本发明实施例提供的无线连接方法实现的前提是：AP检测当前连接的终端的访问状态之前，用户已经通过AP设置好了该终端的访问状态，即S401-S403。
需要说明的是，终端的访问状态的设置是由用户设置和决定的，也是可以改变的。
可选的，终端的访问状态可以包括：信任状态和非信任状态。
例如，终端的访问状态在被设置为信任状态时，该终端发送自己的MAC地址至该AP，以供该AP检测终端的访问状态时使用，且该AP在接收到上述终端发送的MAC地址后，通过加密算法将终端的MAC进行加密，并将加密后的加密信息(将MAC地址加密后的字符串)发送至终端，成为 终端中预存的加密信息，以及终端接收AP发送的后台服务的配置信息，并安装后台服务。
需要说明的是，本发明实施例中的后台服务为可以接收AP发送的更新后的无线配置信息的相关服务，终端在安装上该后台服务时，才可以与AP进行无线配置信息的传输功能。
可选的，AP可以通过现有的加密方法对终端的MAC地址进行加密，本发明实施例不作限制。

可选的，本发明实施例中的无线配置信息可以为Wi-Fi配置信息，也可以为其他形式的无线技术的配置信息，本发明实施例不作限制。
AP检测与其连接的终端的信任状态时，首先，由于AP与终端正在连接，因此，AP可以获取该终端的MAC地址，该AP通过检测获取的终端的MAC地址是否存在于预存的MAC地址列表中来判断该终端的访问状态。
需要说明的是，在AP的设置界面进行终端的访问状态的设置时，AP就将该终端的MAC地址保存了，并将该终端的MAC地址经过加密算法加密后，形成加密信息，将该加密信息传输在该终端，由该终端保存与自己对应的该加密信息，即终端中预存的加密信息，这样，就通过AP设置好了该终端的访问状态为信任状态。若要设置当前连接的终端的访问状态为非信任状态时，则AP不保存该终端的MAC地址，也不发送加密信息至终端， 即终端中未有预存的加密信息。
示例性的，当手机1与无线路由器连接，且要改变无线路由器中的无线密码时，无线路由器向手机1发起检测请求，读取手机1的MAC地址，判断该手机1的MAC地址是否在无线路由器中预存的MAC地址列表中。
S405、MAC地址存在于预存的MAC地址列表中时，AP接收终端中预存的加密信息。
AP获取终端的MAC地址，并检测该终端的MAC地址是否存在于预存的MAC地址列表中之后，若AP中预存的MAC地址列表中有该终端的MAC地址，则该AP获取该终端中预存的加密信息。
需要说明的是，用户在AP的Web UI设置终端的访问状态时，AP将获取的访问状态为信任状态的终端的MAC地址都保存，形成预存的MAC地址列表，由于连接AP的终端的访问状态为信任状态的可以不止一个，因此，AP中保存的MAC地址也可以不止一个。
可以理解的是，AP可以通过校验终端的MAC地址是否与预存的信任终端的MAC地址一致来初步判断终端的访问状态。但是，由于非法终端可以伪装自己的MAC地址与信任状态的终端的MAC地址一致，因此，最优的方案是AP在判断终端的MAC地址存在于预存的MAC地址列表中时，获取终端中的加密信息。
例如，AP可以发送获取加密信息的请求至终端，终端中若有加密信息，则发送该加密信息至AP。
S406、AP对加密信息进行解密，检测解密后的加密信息是否与MAC地址一致。
AP获取终端中预存的加密信息之后，该AP通过与加密算法相应的解密算法对加密信息进行解密，然后，该AP检测解密后的加密信息是否与终端的MAC地址一致。
需要说明的是，加密信息是将访问状态为信任状态的终端的MAC地址进行了加密，因此，解密后的加密信息为终端的MAC地址。
可以理解的是，AP将直接获取的终端的MAC地址与预存的MAC地址列表对比后，排除MAC地址不在预存的MAC列表中的非信任状态的终端，然后，通过与终端中的加密信息的对比，去除伪装MAC地址的终端。
S407、解密后的加密信息与MAC地址一致时，AP确定终端的访问状态为信任状态。
AP对加密信息进行解密之后，解密后的加密信息(终端的MAC地址)与终端的MAC地址一致时，该AP检测或确定该终端的访问状态为信任状态。
可以理解的是，AP将直接获取的终端的MAC地址与预存的MAC地址列表对比后，排除MAC地址不在预存的MAC列表中的非信任状态的终端，然后，通过与终端中的加密信息的对比，去除伪装MAC地址的终端，于是，解密后的加密信息与检测的终端的MAC地址一致时，AP就确定了该终端的访问状态为信任状态，这样，提高了AP验证终端的访问状态的安全性和可靠性。
S408、解密后的加密信息与MAC地址不一致时，AP确定终端的访问状态为非信任状态。
AP对加密信息进行解密之后，解密后的加密信息(终端的MAC地址)与终端的MAC地址不一致时，该AP检测或确定该终端的访问状态为非信任状态。
可以理解的是，AP将直接获取的终端的MAC地址与预存的MAC地址列表对比后，排除MAC地址不在预存的MAC列表中的非信任状态的终端，然后，通过与终端中的加密信息的对比，去除伪装MAC地址的终端。于是，解密后的加密信息与检测的终端的MAC地址不一致时，AP确定了 该终端的访问状态为非信任状态，这样，即使有终端伪装了自己的MAC地址，但是，AP还是可以将伪装的终端检测出来，从而提高了AP验证终端的访问状态的安全性和可靠性。
需要说明的是，本发明实施例中的S407和S408为S406之后的可选步骤，根据实际检测情况选择其中一个步骤执行；也就是说，在本发明实施例中，S406之后，可以执行S407，也可以执行S408，例如执行顺序可以根据实际情况而定，本发明实施例不作限制；并且，S407或S408执行完后，本次处理流程就结束了。

AP检测终端的MAC地址是否存在于预存的MAC地址列表中之后，若在该AP预存的MAC地址列表中没有终端的MAC地址，则表明该终端的访问状态为非信任状态。
可以理解的是，AP中的预存MAC地址列表中都没有与终端的MAC地址一致的，表征该终端未被设置为信任状态的终端。
S410、MAC地址存在于预存的MAC地址列表中时，AP未获取到终端中预存的加密信息时，AP检测终端的访问状态为非信任状态。
终端的MAC地址存在于预存的MAC地址列表中时，AP去获取终端中预存的加密信息，此时，若AP中未获取到该终端中的加密信息，即该终端中没有加密信息时，则AP可以确定该终端的访问状态为非信任状态。
需要说明的是，本发明实施例中的S405-S408、S409和S410为S404之后的可选步骤，根据实际检测情况选择其中一个步骤执行；也就是说，在本发明实施例中，S404之后，可以执行S405-S408，也可以执行S409，还可以执行S410，例如执行顺序可以根据实际情况而定，本发明实施例不作限制；并且，S405-S408、S409或S410执行完后，本次处理流程就结束 了。
