下面通过具体实施方式结合附图对本发明作进一步详细说明。
参考图 1 , 本实施例中的网络连接系统包括：
无线终端， 用于向计算机系统发起网络连接请求， 本实施例中的无线 终端具备 IPv4 和 IPv6 单栈或双栈连网功能， 该无线终端可以是 USB Modern, 无线数据卡（ Wireless Data Card )、 手机终端等， 也可以是笔记本、 IPAD等具有相应无线上网功能的其他终端；
终端设备特征存储模块， 用于存储终端特征和与所述终端特征对应的 连网策略； 终端设备特征存储模块存储的终端特征可根据终端类型和 /或端 口类型、 数量和 /或终端所支持的通信能力等不同而具体划分， 对应每种终 端特征存储有一种连网策略， 终端监控模块， 用于检测到有无线终端发起网络连接请求后 （此时无 线终端与计算机系统已经建立连接）， 获取该无线终端的终端特征， 根据该 无线终端的终端特征在终端设备特征存储模块中查询是否有与该无线终端 相对应的连网策略； 如有， 则根据该无线终端的终端特征在计算机系统中 添加与该无线终端对应的网络服务， 并发送启动指令给终端管理模块； 终端管理模块， 用于接收到终端监控模块发送的启动指令后， 通过终 端监控模块获取与无线终端对应的连网策略； 将获取的连网策略提供给用 户； 终端管理模块根据终端监控模块获取连网策略具体为， 先从终端监控 模块获取该无线终端的终端特征， 然后根据获取的终端特征在终端设备特 征存储模块中查找对应的连网策略即可； 或者直接由终端监控模块在终端 设备特征存储模块中获取到连网策略， 然后终端管理模块直接从终端监控 模块获取该连网策略；
终端管理模块在接收到用户根据其提供的连网策略发送的连网操作指 令后， 根据该连网操作指令控制无线终端实现网络连接。
可见， 本实施例中可通过预先存储的终端特征和与各终端特征对应连 网策略， 当检测到有无线终端发起连接请求后， 根据该无线终端中的终端 特征为其选择合适的连网策略， 不需要使用不同的终端管理系统进行连网， 降低了系统的开发难度， 提高了系统的可靠性， 更便于用户的使用， 提高 了用户体验的满意度。
参见图 2, 本实施例中的系统还包括驱动模块， 该驱动模块用于驱动无 线终端， 将无线终端虚拟为端口设备； 终端特征则包括端口的类型和数量， 终端监控模块可通过驱动模块获取发起通信连接的无线终端的端口的类型 和数量。 具体的， 驱动模块可将无线终端的端口虚拟为串口， 进行通信或 通过 PPP协议进行拨号上网； 对于符合 NDIS标准规范的无线终端， 可将 无线终端虚拟为以太网口， 然后根据协议规范进行网络连接； 无线终端的 端口的类型和数量则可包括虚拟的串口和以太网口的类型和数量。
参见图 3 , 本实施例中的系统还可进一步包括通信指令库， 该通信指令 库用于存储通信指令， 终端特征还可包括终端支持 IPV4和 IPV6单栈和 /或 双栈的能力信息， 即终端的通信能力信息， 终端监控模块用于通过通信指 令库存储的相应的通信指令获取当前发起网络连接请求的无线终端的支持 IPV4和 IPV6单栈和 /或双栈的能力信息， 即获取当前发起网络连接请求的 无线终端的通信能力信息。 本实施例中， 通信指令库所存储的通信指令可 包括 USB协议通信指令、 芯片接口指令、 3GPP ( 3rd Generation Partnership Project )协议规定的注意（Attention, AT )指令， 终端监控模块可根据实际 情况选择相应的通信指令， 从当前发起网络通信连接请求的无线终端获取 该终端支持 IPV4和 IPV6单栈和 /或双栈的能力信息。
由上可知， 本实施例中的终端特征可包括端口的类型和数量、 和终端 支持 IPV4和 IPV6单栈和 /或双栈的能力信息， 为不同的终端特征配置连网 策略时， 则具体根据该终端特征具体包括的端口的类型和数量、 和终端支 持 IPV4和 IPV6单栈和 /或双栈的能力信息为其选择合适的连网策略进行配 置。 终端监控模块在获取到烦请网络连接请求的终端特征后， 在终端设备 特征存储模块中先找到与该终端特征匹配的终端特征后， 即可找到与该无 线终端匹配的连网策略， 因此不需要使用不同的终端管理系统来实现连网， 降低了系统开发难度和成本， 同时也提高了系统的可靠性。 值得注意的是， 为了区分各无线终端， 本实施例中的终端特征还可进一步包括终端标识， 该终端标识可以是终端的唯一标识， 也可以使终端的端口标识， 具体终端 标识的具体选择具体可根据实际情况进行选择。
本实施例中， 终端管理模块将所选定的连网策略提供给用户时， 具体 可通过特定的交互界面（User Interface, UI )将连网策略呈现给用户， 以供 用户根据该连网策略进行具体的连网操作， 例如进行连网参数的设置、 连 网操作等， 用户在进行上述操作时， 对应的向终端管理模块发送相应的连 网操作指令； 终端管理模块在接收到用户根据连网策略发送的连网操作指 令后， 根据该连网操作指令控制无线终端实现网络连接具体可包括：
终端监控模块根据用户发送的连网操作指令， 以及根据相应的协议规 范向终端监控模块发送连网控制指令， 通过终端监控模块控制无线终端进 行连网 ,例如通过终端监控模块控制无线终端进行 IPv4和 IPv6单栈或双栈 连网。
值得注意的是， 本实施例中的终端设备特征存储模块、 终端管理模块、 终端监控模块、 通信指令库和驱动模块可以是计算机系统中的部分， 具体 可为计算机操作系统中的一部分， 该操作系统可为 Windows系统， Mac系 统或 Linux系统，也可为其它智能操作系统。但本实施例中并不排除将上述 模块设置在操作系统以外的其他部分。
