本发明提供一种共享WIFI的方法。
参照图1，图1为本发明共享WIFI的方法第一实施例的流程示意图。
在第一实施例中，所述共享WIFI的方法包括：
步骤101，接收用户设备发送的接入WIFI的报文；
具体的，参考图2，图2为本发明提供的一种共享WIFI的系统结构图。如图2所示，首先家庭网关和无线局域网关(Wireless Local Area Networks Gateway，WLAN Gateway)之间要建立起通用路由封装(Generic Routing Encapsulation，GRE)隧道。在无线用户设备需要接入Internet网络的情况下，无线用户设备会向家庭网关发送报文，所述家庭网关接收用户设备发送的报文。
步骤102，在所述用户设备为第一用户设备的情况下，封装所述报文为第一通用路由封装GRE报文；
其中，所述用户设备分为公共设备及私有设备，私有设备一般为该家庭网关持有者的设备，即描述中的第二用户设备，私有用户可接入私有的WIFI热点，有权设置该WIFI的用户名及密码。而公共设备一般是外部用户设备，即第一用户设备，接入的是公共WIFI热点，并无权设置该WIFI热点的用户名及密码等。
步骤103，通过GRE隧道将所述第一GRE报文发送给无线局域网关WLAN Gateway，以使得所述WLAN Gateway解封装所述第一GRE报文，并根据解封后的所述第一用户设备报文内容确定转发到DHCP Server或是Internet。
具体的，公共设备需要接入家庭网关的WIFI热点时，家庭网关将所述第一GRE报文通过GRE隧道传输，在隧道对端即WLAN Gateway对收到的第一GRE报文进行解封装，解封后成普通的以太报文。对于动态主机配置协议(Dynamic Host Configuration Protocol，DHCP)报文，隧道对端的DHCP Server根据请求信息分配地址。对于其他数据报文，在解封装后直接接入Internet。
本发明实施例通过接收无线用户设备发送的报文；在所述用户设备为第一用户设备的情况下，封装所述请求报文为第一通用路由封装GRE报文；通过GRE隧道将所述第一GRE报文发送给无线局域网关WLAN Gateway，以使得所述WLAN Gateway解封装所述第一GRE报文，并根据解封后的所述第一用户设备报文内容确定转发到DHCP Server或是Internet。在所述用户设备为第二用户设备时，报文通过宽带接入服务器后直接送到Internet。从而使得公共用户和私有用户可以共同分享WIFI，并且公共用户和私有用户业务分离，使得用户可以更加方便、安全、快捷的接入网络，节省了运营企业的投资成本，提高了资源利用率。
如图3所示，图3为本发明共享WIFI的方法第二实施例流程示意图。在第一实施例的基础上，步骤103之后还包括：
