Description

实现WLAN共享的方法、系统和WLAN共享注册服务器 技术领域
本发明实施例涉及无线局域网(WLAN，Wireless Local Area Network)技术，尤指一种实现WLAN共享的方法、系统和WLAN共享注册服务器
背景技术
私有无线局域网(WLAN，Wireless Local Area Network)是由用户使用无线设备自行组建的、供用户自己使用的小型局域网。私有WLAN通常由私有WLAN网关如无线路由器，及移动终端组成。
用户可以通过为无线路由器设置接入凭证，比如接入密码来限制外部用户和终端的访问。目前，实现私有WLAN共享的方法包括两种：一种是，私有WLAN的所有者不设置无线路由器的接入密码，以对所有移动终端开放接入权限；另一种是，无线路由器的所有者将无线路由器的接入密码告知指定人，以对指定人开放接入权限。
出于信息安全等方面的考虑，目前的私有WLAN都设置有接入密码，因此，虽然私有WLAN高度普及，但是却类似信息接入的孤岛，无法实现共享。
一个典型的场景就是在公寓社区内，几乎大部分住户都部署有私有WLAN，而且由用户使用无线设备自行组建的、供用户自己使用的一种松散的WLAN部署方式。基本在社区内随处都能搜到可用的WLAN，但是却因为无法获取这些私有WLAN的接入密码，而无法使用这些可用的WLAN接入。
在一些现有的处理方式中，如申请号为CN201210017169.9，发明名称为“私有WLAN共享方法、系统、服务器、终端及网关管理服务器”的申请中，通过定义的私有WLAN共享服务器，维护私有WLAN的网络标识和接入凭证，其中，私有WLAN的网络标识包括唯一的服务集标示符(SSID)。由于使用唯一的私有WLAN的网络标识作为标识，因此，这种处理方式仅适用于高度可控的WLAN部署如某运营商建立的WLAN覆盖部署，而对于松散的WLAN部署，当不同的WLAN网络使用相同的SSID时，无法实现共享。

WLAN共享注册服务器，设置为接收来自WLAN网络的注册，保存注册的WLAN设备所属WLAN网络的私有WLAN网络标识和接入凭证；接收来自用户设备的查询并将查询到的已注册的私有WLAN网络标识对应的接入凭证返回给用户设备；这里，本领域技术人员容易理解，如果WLAN设备支持自动注册，则注册请求来自WLAN设备；如果WLAN设备不支持自动注册，则注册请求来自WLAN管理员。
WLAN设备，设置为向WLAN共享注册服务器注册；对请求接入的用户设备进行认证并将其接入所属的私有WLAN网络；
用户设备(UE，User Equipment)，设置为利用搜索到的私有WLAN网络标识向WLAN共享注册服务器发起查询，接收到已注册的私有WLAN网络标识对应的接入凭证，利用获得的接入凭证向对应的WLAN设备发起接入请求。
其中，
用户设备还设置为，在发起查询时，将自身地理位置信息发送给WLAN共享注册服务器。即WLAN共享注册服务器还设置为，接收来自所述UE的UE自身的地理位置信息；相应地，
WLAN共享注册服务器还设置为，根据接收到的地理位置信息定位WLAN设备，此时，所述查询到的已注册的私有WLAN网络标识为定位到的已注册的私有WLAN网络标识，也就是说，此时，WLAN共享注册服务器仅将定位到的已注册的私有WLAN网络标识对应的接入凭证返回给用户设备。或者，

进一步地，
用户设备还设置为，登录WLAN共享注册服务器；此时，
WLAN共享注册服务器还设置为，根据预先设置的查询策略及用户设备的登录信息，在确定允许向用户设备返回查询结果时，向用户设备返回接入凭证；在确定出禁止向用户设备返回查询结果时，返回查询失败。
进一步地，WLAN共享注册服务器还设置为，加密查询到的接入凭证。
其中，用户设备为具有WLAN访问能力的终端类用户设备，比如智能手机、Pad类平板电脑、笔记本电脑或其它用户智能设备。
其中，WLAN设备与WLAN共享注册服务器之间为I1接口，UE与WLAN共享注册服务器之间I2接口，UE与WLAN设备之间为I3接口。
图2为本发明实施例中WLAN共享注册服务器的组成结构示意图，如图2所示，至少包括注册模块和登录模块，其中，
注册模块，设置为接收来自WLAN网络的注册，保存注册的WLAN设备所属WLAN网络的私有WLAN网络标识和接入凭证；这里，本领域技术人员容易理解，如果WLAN设备支持自动注册，则注册请求来自WLAN设备；如果WLAN设备不支持自动注册，则注册请求来自WLAN管理员。

当用户设备在发起查询并将自身地理位置信息发送给WLAN共享注册服务器时，WLAN共享注册服务器还包括定位模块，设置为根据接收到的地理位置信息定位WLAN设备；
此时，查询模块设置为，接收来自用户设备的查询，仅将定位到的已注册的私有WLAN网络标识对应的接入凭证返回给用户设备。或者，
注册模块还设置为，在WLAN设备发起注册时，同时保存WLAN设备 上报的地理位置信息；此时，查询模块还设置为，匹配接收到的地理位置信息和自身存储有的WLAN设备的地理位置信息，仅将匹配到的已注册的私有WLAN网络标识对应的接入凭证返回给用户设备。这里匹配是指的二者的地理位置信息显示的位置相同或在预设距离范围内等，本领域技术人员知道，只要能满足后续UE能接入信号足够强的WLAN网络即可。
进一步地，
查询模块还设置为，加密查询到的接入凭证。
进一步地，WALN共享注册服务器还包括登录模块，设置为接收来自用户设备的登录请求；
此时，查询模块还设置为，根据预先设置的查询策略及用户设备的登录信息，在确定允许向用户设备返回查询结果时，向用户设备返回接入凭证；在确定出禁止时，向用户设备返回查询失败。
本发明实施例的应用场景包括但不限于：如一个社区内的松散WLAN设备可以通过小区一级的WLAN共享注册服务器，实现在小区内的WLAN直接访问。或者，由类似Tencent、百度一类互联网公司提供WLAN共享注册服务器，UE安装应用(App)，实现注册以及WLAN访问。发起注册的愿意共享的WLAN设备越多，UE越能无缝接入可用的私有WLAN。
图3为本发明实施例中实现WLAN共享的方法的流程图，如图3所示，包括：
步骤300：WLAN共享注册服务器获取注册的WLAN设备所属WLAN网络的私有WLAN网络标识和接入凭证。
本步骤中，愿意共享的WLAN网络，WLAN网络中的WLAN设备(WLAN网关如无线路由器)可以通过注册请求，将自身的私有网络标识如SSID和接入凭证如接入密码，注册到WLAN共享注册服务器中；
或者，愿意共享的WLAN网络，如果WLAN网络中的WLAN设备不能自动发起注册请求时，可以通过WLAN管理员向WLAN共享注册服务器发起注册请求，将WLAN网络的私有网络标识如SSID和接入凭证如接入密码，注册到WLAN共享注册服务器中。
本步骤中，只要是愿意共享其WLAN网络的WLAN设备或用户，均可以通过向WLAN共享注册服务器的注册过程，将其自身的WLAN网络标识和对应的接入凭证存储在WLAN共享注册服务器中，这样方便了需要接入WLAN网络的用户的查询和接入。
步骤301：WLAN共享注册服务器根据用户设备的查询，将查询到的已注册的私有WLAN网络标识对应的接入凭证返回用户设备。
本领域技术人员知道，当UE打开WLAN功能，会自动搜索附近的WLAN网络，并获得附近可用的WLAN列表，在WLAN列表中包含有WALN网络标识如SSID。
本步骤中，UE可以通过查询请求向WLAN共享注册服务器发起查询请求，查询信息至少包括UE搜索到的WLAN网络标识如SSID。
如果UE获得的WLAN列表中包含超过一个如两个或两个以上WLAN网络标识，UE发起的查询请求包括：每次查询请求仅查询一个WLAN网络标识，发起多次查询请求来查询不同的WLAN网络标识；或者，在一次查询请求中包含搜索到的WLAN列表中的所有WLAN网络标识。
本步骤中，将查询到的已注册的私有WLAN网络标识对应的接入凭证返回用户设备包括：
WLAN共享注册服务器查询本地是否存储有查询请求中携带的WLAN网络标识，如果存储有，将该WLAN网络标识如SSID及其对应的接入凭证如接入密码携带在查询响应中返回给UE。
在UE获得愿意共享的WLAN网络的WLAN网络标识如SSID和其对应的接入凭证如接入密码后，UE可以选择接入WLAN列表中可用的愿意共享的WLAN网络。UE如何接入可用的WLAN网络属于本领域技术人员的惯用技术手段，并不用于限定本发明实施例的保护范围，这里不再赘述。
需要说明的是，本发明实施例中的WLAN是松散的WLAN部署，因此，存在SSID重名的情况，此时，查询结果包括两组或两组以上具有相同的SSID的WLAN网络的SSID及其对应的接入密码的集合。
如果查询结果中包括有两个或两个以上具有相同的SSID的WLAN网络 的SSID及其对应的接入密码的集合，UE可以从中选用其中一个可用的SSID和接入密码接入WLAN网络，直至认证成功接入WLAN网络。
较佳地，如果在查询请求中还携带有UE自身的地理位置信息，本发明实施例的方法还包括：
WLAN共享注册服务器根据接收到的地理位置信息定位WLAN设备，WLAN共享注册服务器提取定位到的本地存储的WLAN设备对应的私有WLAN网络标识和接入凭证，查询其中是否存储有请求中携带的WLAN网络标识，如果存储有，将该WLAN网络标识如SSID及其对应的接入凭证如接入密码携带在查询响应中返回给UE。这种情况下，WLAN共享注册服务器仅将定位到的已注册的私有WLAN网络标识对应的接入凭证返回给用户设备，减少了所注册WLAN设备的重名带来的问题，简化了拥有海量WLAN设备注册的场景的查询过程，也使得后续用户设备的接入变得简单了。
需要说明的是，在WLAN设备向WLAN共享注册服务器发起注册时，将自身的地理位置信息同时发送给WLAN共享注册服务器，此时，WLAN共享注册服务器可以通过匹配接收到的地理位置信息和自身存储有的WLAN设备的地理位置信息，仅将匹配到的已注册的私有WLAN网络标识对应的接入凭证返回给用户设备。这里匹配是指的二者的地理位置信息显示的位置相同或在预设距离范围内等，本领域技术人员知道，只要能满足后续UE能接入信号足够强的WLAN网络即可。
进一步地，在步骤301之前，本发明实施例的方法还包括：
WLAN共享注册服务器实现对UE的登录的处理获取UE的登录信息：UE向WLAN共享注册服务器发起携带有登录信息的登录请求，WLAN共享注册服务器向UE返回登录响应；此时，
本步骤中的将查询到的已注册的私有WLAN网络标识对应的接入凭证返回用户设备之前还包括：
WLAN共享注册服务器根据预先设置的查询策略及用户设备的登录信息，确定是否允许向用户设备返回查询结果，如果允许，向用户设备返回查询结果；如果禁止，向用户设备返回查询失败。
这里，登录信息中包括但不限于用户等级、用户积分等，确定是否允许向用户设备返回查询结果包括：
WLAN共享注册服务器根据查询策略，如果登录信息中用户等级不够、和/或用户积分不够等，认为本次查询失败；或根据查询策略只对查询中的部分WLAN设备返回其对应的接入密码等等。关于查询策略的具体实现属于本领域技术人员在本发明实施例提供的技术方案基础上容易想到的，并不用于限定本发明实施例的保护范围，这里不再赘述。
进一步地，在将查询到的已注册的私有WLAN网络标识对应的接入凭证返回用户设备之前，该方法还包括：WLAN共享注册服务器加密查询到的接入凭证。如何加密可以采用现有方法实现，这里本领域技术人员的公知技术，加密的具体实现并不用于限定本发明实施例的保护范围，这里强调的是，对返回给UE的查询结果进行加密处理，以进一步保证了愿意共享WLAN网络的安全性。
本发明实施例中，只要是愿意共享其WLAN网络的WLAN设备或用户，均可以通过向WLAN共享注册服务器的注册过程，将其自身的WLAN网络标识和对应的接入凭证存储在WLAN共享注册服务器中。通过本发明实施例提供的技术方案，有效解决了松散WLAN部署的共享问题，适用于松散的WLAN部署。也就是说，只要是存在WLAN部署的地方，均可以通过在WLAN共享注册服务器中的注册，将自身的WLAN网络标识和对应的接入凭证共享给需要的UE。
下面结合具体实施例对本发明实施例的方法进行详细描述。
图4为本发明实施例中实现WLAN共享的方法的第一实施例的流程示意图，如图4所示，包括以下步骤：
步骤400：愿意共享自身所属WLAN网络的WLAN设备，通过消息向WLAN共享注册服务器注册WLAN网络信息，至少包络SSID、接入密码。
进一步地，还可以包括提供用于定位的信息，如WLAN设备的地理位置信息等。
步骤401：UE打开WLAN功能，搜索附近的WLAN网络，并获得附近 可用的WLAN列表。本领域技术人员知道，在WLAN列表中包含有WALN网络标识如SSID。
步骤402：UE通过消息向WLAN共享注册服务器发起查询请求，查询信息至少包括SSID。
如果UE获得的WLAN列表中包含超过一个如两个或两个以上WLAN网络标识，UE发起的查询请求包括：每次查询请求仅查询一个WLAN网络标识，发起多次查询请求来查询不同的WLAN网络标识；或者，在一次查询请求中包含搜索到的WLAN列表中的所有SSID。
步骤403：WLAN共享注册服务器向UE发送查询结果，查询结果包含有查询到的WLAN网络的SSID及其对应的接入密码。
由于WLAN部署可以是松散的WLAN部署，因此，很可能存在SSID重名的情况，也就是说，在查询结果会包含多个具有相同的SSID的WLAN网络的SSID及其对应的密码的集合。
进一步地，WLAN共享注册服务器可以对返回的查询结果进行加密处理。进一步地，加密对于UE的用户是屏蔽即用户不能获取加密密钥，由UE自行完成解密。
步骤404：UE使用获取的WLAN网络的SSID和其接入密码，接入WLAN网络。
需要说明的是，如果查询结果中包含有多个具有相同的SSID的WLAN网络的SSID及其对应的密码的集合，UE可以从中任意选择一个可用的SSID和其接入密码，并向该WLAN网络发起接入请求，在认证成功后接入该WLAN网络。
需要说明的是，如果认证失败，而且查询结果中存在多个可用的WLAN网络的SSID和其接入密码，那么，还包括步骤405：UE可以另外选择一个可用的SSID和其接入密码，重复发起认证的步骤。
图5为本发明实施例中实现WLAN共享的方法的第二实施例的流程示意图，如图5所示，包括以下步骤：

步骤502：UE获取辅助信息，如通过GPS获取UE的地理位置信息等。
步骤503：UE通过消息向WLAN共享注册服务器发起查询请求，查询信息包括SSID和辅助信息如UE的地理位置信息。
如果UE获得的WLAN列表中包含超过一个如两个或两个以上WLAN网络标识，UE发起的查询请求包括：每次查询请求仅查询一个WLAN网络标识，发起多次查询请求来查询不同的WLAN网络标识；或者，在一次查询请求中包含搜索到的WLAN列表中的所有SSID。
步骤504：WLAN共享注册服务器根据接收到的UE的地理位置信息，对已注册的WLAN设备进行定位。
需要说明的是，在WLAN设备向WLAN共享注册服务器发起注册时，如果将自身的地理位置信息同时发送给WLAN共享注册服务器，那么，WLAN共享注册服务器通过匹配接收到的地理位置信息和自身存储有的WLAN设备的地理位置信息，仅将匹配到的已注册的私有WLAN网络标识对应的接入凭证返回给用户设备。这里匹配是指的二者的地理位置信息显示的位置相同或在预设距离范围内等，本领域技术人员知道，只要能满足后续UE能接入信号足够强的WLAN网络即可。
步骤505：WLAN共享注册服务器向UE发送查询结果，查询结果包含定位到的WLAN网络的SSID和接入密码。
这种情况下，WLAN共享注册服务器仅将定位到的已注册的私有WLAN网络标识对应的接入凭证返回给用户设备，减少了所注册WLAN设备的重名带来的问题，简化了拥有海量WLAN设备注册的场景的查询过程，也使得后续用户设备的接入变得简单了。
由于WLAN部署可以是松散的WLAN部署，因此，很可能存在SSID重名的情况，也就是说，在查询结果会包含多个具有相同的SSID的WLAN网络的SSID及其对应的密码的集合。
进一步地，WLAN共享注册服务器可以对返回的查询结果进行加密处理。进一步地，加密对于UE的用户是屏蔽即用户不能获取加密密钥，由UE自行完成解密。
步骤506：UE使用获取的WLAN网络的SSID和其接入密码，接入WLAN网络。
需要说明的是，如果查询结果中包含有多个具有相同的SSID的WLAN网络的SSID及其对应的密码的集合，UE可以从中任意选择一个可用的SSID和其接入密码，并向该WLAN网络发起接入请求，在认证成功后接入该WLAN网络。
需要说明的是，如果认证失败，而且查询结果中存在多个可用的WLAN网络的SSID和其接入密码，那么，还包括步骤507：UE可以另外选择一个可用的SSID和其接入密码，重复发起认证的步骤。
图6为本发明实施例中实现WLAN共享的方法的第三实施例的流程示意图，如图6所示，包括以下步骤：
步骤600：愿意共享WLAN网络的WLAN管理员，通过消息向WLAN共享注册服务器注册WLAN网络信息，至少包络SSID、接入密码，以及共享的WLAN网络的接入设备标识如接入地址等。
进一步地，还可以包括提供用于定位的信息，如WLAN设备的地理位置信息等。

步骤604：WLAN共享注册服务器根据接收到的UE的地理位置信息，对已注册的WLAN设备进行定位。
需要说明的是，在WLAN设备向WLAN共享注册服务器发起注册时，如果将自身的地理位置信息同时发送给WLAN共享注册服务器，那么，WLAN共享注册服务器通过匹配接收到的地理位置信息和自身存储有的WLAN设备的地理位置信息，仅将匹配到的已注册的私有WLAN网络标识对应的接入凭证返回给用户设备。这里匹配是指的二者的地理位置信息显示的位置相同或在预设距离范围内等，本领域技术人员知道，只要能满足后续UE能接入信号足够强的WLAN网络即可。
步骤605：WLAN共享注册服务器向UE发送查询结果，查询结果包含定位到的WLAN网络的SSID和接入密码。
这种情况下，WLAN共享注册服务器仅将定位到的已注册的私有WLAN网络标识对应的接入凭证返回给用户设备，减少了所注册WLAN设备的重名带来的问题，简化了拥有海量WLAN设备注册的场景的查询过程，也使得后续用户设备的接入变得简单了。
由于WLAN部署可以是松散的WLAN部署，因此，很可能存在SSID重名的情况，也就是说，在查询结果会包含多个具有相同的SSID的WLAN网络的SSID及其对应的密码的集合。
进一步地，WLAN共享注册服务器可以对返回的查询结果进行加密处理。进一步地，加密对于UE的用户是屏蔽即用户不能获取加密密钥，由UE自行完成解密。
步骤606：UE使用获取的WLAN网络的SSID和其接入密码，接入WLAN网络。
需要说明的是，如果查询结果中包含有多个具有相同的SSID的WLAN 网络的SSID及其对应的密码的集合，UE可以从中任意选择一个可用的SSID和其接入密码，并向该WLAN网络发起接入请求，在认证成功后接入该WLAN网络。
需要说明的是，如果认证失败，而且查询结果中存在多个可用的WLAN网络的SSID和其接入密码，那么，还包括步骤607：UE可以另外选择一个可用的SSID和其接入密码，重复发起认证的步骤。
