以无线数据卡为例, 本发明无线通讯终端的启用方法, 如图 1 所示, 包括以下步骤:
步骤 100: 在无线数据卡中配置 ECM子设备及 RNDIS子设备; 这里,配置 ECM子设备是为了使无线数据卡可以支持 Linux操作系统、 及 MAC 操作系统; 配置 RNDIS 子设备是为了使无线数据卡可以支持 Windows操作系统; 其中, ECM子设备与 RNDIS子设备为两个独立的子 设备, 即: 无线数据卡在使用时, ECM子设备与 RNDIS子设备不进行任 何信息的交互; 由于目前的操作系统主要包括: Linux操作系统、 MAC操作系统、 及 Windows操作系统, 因此,可以在无线数据卡中配置 ECM子设备及 RNDIS 子设备, 以使无线数据卡能适用于不同的操作系统;
在配置 ECM子设备时, 具体包括: 依据 ECM配置设备、 接口、 端点 的描述符信息、 以及数据流、 控制流的驱动; 其中, 配置设备、 接口、 端 点的描述符信息是为了使无线数据卡在使用时,成为支持 ECM的无线数据 卡, 即: 支持 Linux操作系统、 及 MAC操作系统的无线数据卡; 配置数据 流、 控制流的驱动, 是为了使无线数据卡在使用时, 可以对数据流及控制 流进行控制; ECM子设备的硬件的配置与现有的无线数据卡的硬件配置相 同;
在配置 RNDIS子设备时, 具体包括: 依据 RNDIS配置设备、 接口、 端点的描述符信息、 以及数据流、 控制流的驱动; 其中, 配置设备、 接口、 端点的描述符信息是为了使无线数据卡在使用时, 成为支持 RNDIS的无线 数据卡, 即: 支持 Windows操作系统; 配置数据流、 控制流的驱动, 是为 了使无线数据卡在使用时, 可以对数据流及控制流进行控制; RNDIS子设 备的硬件的配置与现有的无线数据卡的硬件配置相同。
步骤 101 : 无线数据卡插入计算机主机并在上电后, 向主机的操作系统 枚举无线数据卡为 RNDIS设备,之后判断主机的操作系统是否支持 RNDIS 设备, 确定主机的操作系统支持 RNDIS设备后, 通过主机的操作系统的驱 动程序实现无线数据卡的自动安装; 确定主机的操作系统不支持 RNDIS设 备后, 向主机的操作系统枚举无线数据卡为 ECM设备, 通过主机的操作系 统的驱动程序实现无线数据卡的自动安装;
这里,所述向主机的操作系统枚举无线数据卡为 RNDIS设备的时机为: 无线数据卡收到主机的操作系统下发的 USB描述符请求; 其中, 在无线数 据卡上电后, 主机的操作系统会检测到无线数据卡, 并在检测到无线数据 卡后, 向无线数据卡下发 USB描述符请求; 主机的操作系统检测到无线数 据卡的具体处理流程与现有技术的处理流程完全相同, 这里不再赘述; 向主机的操作系统枚举无线数据卡为 RNDIS设备, 具体为:
向主机的操作系统上报与 RNDIS子设备对应的设备、 接口、 以及端点 的描述符信息; 其中, 在描述符信息中, 设置 bcdDevice参数的值大于零, 如此, 主机的操作系统才会在加载驱动程序的过程中, 向无线数据卡下发 MS OS Descriptor请求; 上报与 RNDIS子设备对应的设备、 接口、 以及端 点的描述符信息后, 表明无线数据卡目前处于 RNDIS配置状态, 即: 无线 数据卡为支持 RNDIS的设备;
所述判断主机的操作系统是否支持 RNDIS设备, 具体为:
在规定时长内是否收到主机的操作系统下发的 MS OS Descriptor请求; 如果在规定时长内收到主机的操作系统下发的 MS OS Descriptor请求, 则 认为主机的操作系统支持 RNDIS设备, 如果在规定时长内, 未收到主机的 操作系统下发的 MS OS Descriptor描述符请求, 则认为主机的操作系统不 支持 RNDIS设备;
在实际应用过程中, 可以在无线数据卡向主机的操作系统上报与 RNDIS子设备对应的设备、接口、 端点的描述符信息的同时, 启动定时器, 或者, 可以在无线数据卡上电后, 就启动定时器; 在实际应用时, 由于主 机的操作系统检测到无线数据卡并向无线数据卡下发 USB描述符请求的时 间非常短, 因此, 为了方便操作, 可以在无线数据卡上电后就启动定时器; 在定时器的时长内, 如果收到了主机的操作系统下发的 MS OS Descriptor 请求, 则认为主机的操作系统支持 RNDIS设备, 定时器超时后, 如果未收 到主机的操作系统下发的 MS OS Descriptor请求, 则认为主机的操作系统 不支持 RNDIS设备;
其中, 可以依据主机的操作系统在根据上报的描述符信息搜索相应的 驱动程序、 以及在找到驱动程序后正确加载的时长设置定时器的时长, 一 般主机的操作系统搜索驱动程序并正确加载的时长为几秒钟, 因此, 可以 设置定时器的时长为几秒, 比如: 3秒、 4秒等等;
主机的操作系统收到无线数据卡上报的设备、 接口、 以及端点的描述 符信息后, 依据描述符信息搜索描述符信息对应的驱动程序, 如果找到描 述符对应的驱动程序, 则正确加载描述符对应的驱动程序, 并在加载过程 中, 会向无线数据卡下发 MS OS Descriptor请求; 如果没有找到, 则不进 行任何处理; 因此, 无线数据卡可以据此确定主机的操作系统是否支持 RNDIS设备;
相应的, 无线数据卡收到 MS OS Descriptor请求后, 会依据 RNDIS向 主机的操作系统返回响应, 以便主机的操作系统能根据返回的响应完成驱 动程序的加载, 同时无线数据卡清除定时器; 其中, 向操作系统返回响应 的具体处理过程与现有技术的具体处理过程完全相同, 这里不再赘述; 该方法还可以进一步包括:
通过主机的操作系统的驱动程序实现无线数据卡的自动安装后, 无线 数据卡与主机的操作系统进行 RNDIS请求、 及指令的交互, 以便无线数据 卡可以进入工作状态;
无线数据卡与主机的操作系统进行 RNDIS请求、 及指令的交互的具体 处理过程与现有的处理过程完全相同, 这里不再赘述;
所述向主机的操作系统枚举无线数据卡为 ECM设备, 具体为: 向主机的操作系统上报与 ECM子设备对应的设备、接口、 以及端点的 描述符信息; 其中, 上报与 ECM子设备对应的设备、 接口、 以及端点的描 述符信息后, 表明无线数据卡目前处于 ECM配置状态, 即: 无线数据卡为 支持 ECM的设备;
主机的操作系统收到无线数据卡上报的设备、 接口、 以及端点的描述 符信息后, 依据描述符信息找到描述符信息对应的驱动程序后正确加载, 之后与无线数据卡进行 ECM请求、 及指令的交互, 以便无线数据卡能在 ECM状态下工作; 其中, 主机的操作系统与无线数据卡进行 ECM请求、 及指令的交互的具体处理过程与现有的处理过程完全相同, 这里不再赘述; 这里, 由于现有的操作系统会支持 ECM设备和 RNDIS设备两种设备 中的一种或两种, 因此, 不会出现主机的操作系统依据 ECM子设备对应的 设备、 接口、 以及端点的描述符信息未能找到对应的驱动程序的情况。
下面结合实施例对本发明再作进一步详细的描述。
本实施例以无线数据卡为例, 本实施例无线数据卡的启用方法, 如图 2 所示, 包括以下步骤:
步骤 200: 在无线数据卡中配置 ECM子设备及 RNDIS子设备, 之后 执行步骤 201 ;
这里, 在配置 ECM子设备时, 具体包括: 依据 ECM配置设备、 接口、 端点的描述符信息、 以及数据流、 控制流的驱动;
在配置 RNDIS子设备时, 具体包括: 依据 RNDIS配置设备、 接口、 端点的描述符信息、 以及数据流、 控制流的驱动。
步骤 201 : 无线数据卡插入计算机主机, 并在上电后, 启动定时器, 主 机的操作系统检测到无线数据卡,之后向无线数据卡下发 USB描述符请求。
步骤 202: 无线数据卡收到 USB描述符请求后, 向主机的操作系统上 报与 RNDIS子设备对应的设备、 接口、 以及端点的描述符信息;
这里, 上报与 RNDIS子设备对应的设备、 接口、 以及端点的描述符信 息后, 表明无线数据卡目前处于 RNDIS配置状态, 即: 无线数据卡为支持 RNDIS的设备;
所述描述符信息中的 bcdDevice参数的值大于零。
步骤 203 : 主机的操作系统判断是否支持 RNDIS设备, 如果是, 则执 行步骤 204, 否则, 执行步骤 207;
这里, 所述主机的操作系统判断是否支持 RNDIS设备, 具体为: 主机的操作系统收到描述符信息后, 依据描述符信息搜索对应的驱动 程序, 如果搜索到对应的驱动程序, 则认为主机的操作系统支持 RNDIS设 备, 否则, 认为主机的操作系统不支持 RNDIS设备, 不进行任何操作。
步骤 204: 加载描述符对应的驱动程序, 并在加载过程中向无线数据卡 下发 MS OS Descriptor请求。
步骤 205: 无线数据卡收到主机的操作系统下发的 MS OS Descriptor 请求后, 清除定时器, 并依据 RNDIS向主机的操作系统返回响应。
步骤 206: 主机的操作系统收到响应后, 完成驱动程序的加载, 之后与 无线数据卡进行 RNDIS请求、及指令的交互,使无线数据卡进入工作状态。
步骤 207: 定时器超时后, 无线数据卡的总线重新启动, 之后向主机的 操作系统上报与 ECM子设备对应的设备、 接口、 以及端点的描述符信息; 这里, 无线数据卡的总线重新启动后, 才能使无线数据卡处于 ECM状 态。
步骤 208: 主机的操作系统收到无线数据卡上报的设备、接口、 以及端 点的描述符信息后, 依据描述符信息找到描述符信息对应的驱动程序后正 确加载, 之后与无线数据卡 ECM请求、 及指令的交互, 以便无线数据卡能 在 ECM状态下工作。
