为了减小主机的耗电量,本发明实施例提供了一种带 U盘功能的 USB 数据卡进入休眠状态的方法, 系统及装置, 该方法中该带 U盘功能的 USB 数据卡包括两种配置信息, 分别为第一 USB数据卡配置信息和第二 USB 数据卡配置信息,其中该第一 USB数据卡配置信息为具有 U盘功能的 USB 数据卡的配置信息, 第二 USB数据卡配置信息为不带 U盘功能的 USB数 据卡的配置信息。
为了使本发明所要解决的技术问题、 技术方案及有益效果更加清楚、 明白, 以下结合附图和实施例, 对本发明进行进一步详细说明。 应当理解, 此处所描述的具体实施例仅仅用以解释本发明, 并不用于限定本发明。
图 2为本发明实施例提供的带 U盘功能的 USB数据卡进入休眠状态的 流程示意图, 如图 2所示, 该流程包括以下步骤:
S201 : USB数据卡在与主机枚举过程中, 将所述第一 USB数据卡配置 信息发送给所述主机。
USB数据卡在与主机进行枚举的过程中,首先将第一 USB数据卡配置 信息发送给主机,即将该带 U盘功能的 USB数据卡的配置信息发送给主机。
S202: USB数据卡接收所述主机发送的配置信息切换指令。
其中, 主机发送配置信息切换指令包括:
所述主机判断在设定的时间长度内是否接收到对所述 USB数据卡的操 作数据信息;
当未接收到对所述 USB数据卡的操作数据信息时,向所述 USB数据卡 发送配置信息切换指令。
S203: USB数据卡根据所述配置信息切换指令, 将所述第二 USB数据 卡配置信息发送给所述主机, 之后进入休眠状态。
S201中, 由于当前 USB数据卡向主机枚举的为带 U盘功能的数据卡, 因此此时主机认为该 USB数据卡为带 U盘功能的数据卡, S203中,该 USB 数据卡根据接收到的主机发送的配置信息切换指令, 再次与主机进行枚举, 将自身的第二 USB数据卡配置信息发送给主机,即将自身不带 U盘功能的 USB数据卡的配置信息发送给主机。此时由于 USB数据卡向主机枚举了第 二 USB数据卡配置信息, 因此主机认为该 USB数据卡为一个不带 U盘功 能的 USB数据卡, 该 UBS数据卡与主机遵循 USB接口规范, 因此在规定 的时间间隔内没有数据交换, 主机就会通知 USB数据卡进入休眠状态, 从 而实现带 U盘功能的 USB数据卡进入休眠状态。
图 3为本发明实施例提供的带 U盘功能的 USB数据卡进入休眠状态的 系统的结构示意图, 该系统中所述 USB数据卡 31包括: 第一 USB数据卡 配置信息和第二 USB数据卡配置信息,其中,所述第一 USB数据卡配置信 息为具有 U盘功能的 USB数据卡的配置信息, 第二 USB数据卡配置信息 为不带 U盘功能的 USB数据卡的配置信息, 该系统包括:
USB数据卡 31 , 设置为在与主机 32枚举过程中, 将所述第一 USB数 据卡配置信息发送给所述主机 32; 以及接收所述主机 32发送的配置信息切 换指令; 以及根据所述配置信息切换指令, 将所述第二 USB数据卡配置信 息发送给所述主机 32, 之后进入休眠状态;
主机 32, 设置为接收所述 USB数据卡 31发送的配置信息; 以及向所 述 USB数据卡 31发送配置信息切换指令。
具体的, 图 4为发明实施例提供的主机和带 U盘功能的 USB数据卡的 结构示意图, 在该图 4中, UI和 USB主机控制器位于主机内, 该带 U盘 功能的 USB数据卡包括第一 USB数据卡配置信息和第二 USB数据卡配置 信息, 其中, 该第一 USB数据卡配置信息为带 U盘功能的 USB数据卡的 配置信息,即当该 USB数据卡向主机枚举了该第一 USB数据卡配置信息后, 主机确定该 UBS数据卡为具有 U盘功能和数据卡功能的 USB数据卡, 当 该 USB数据卡向主机枚举了该第而 USB数据卡配置信息后, 主机确定该 UBS数据卡为不带 U盘功能的 USB数据卡, 即此时该 USB数据卡只有数 据卡功能。
当该 USB数据卡插入到主机侧的 USB接口上时, 该 USB数据卡与主 机枚举,将自身的第一 USB数据卡配置信息发送给主机,主机的 USB主机 控制器接收到该 USB数据卡发送的第一 USB数据卡配置信息后, 确定该 USB数据卡此时具有 U盘功能和数据卡功能。 主机的 UI通过该 USB主机 控制器确定该 USB数据卡的功能, 之后 UI判断在设定的时间长度内是否 接收到对该 USB数据卡的操作数据信息, 当在设定的时间长度内接收到操 作数据信息时, 将该操作数据信息发送给所述 USB数据卡, 当在设定的时 间长度内未接收到对所述 USB数据卡的操作数据信息时,向所述 USB数据 卡发送配置信息切换指令。
USB数据卡接收到主机 UI发送的配置信息切换指令后,再次与主机进 行枚举,将自身的第二 USB数据卡配置信息发送给主机,主机的 USB主机 控制器接收到 USB数据卡发送的第二 USB数据卡配置信息后,确定该 USB 数据卡此时只有数据卡功能。 主机 UI通过该 USB主机控制器确定该 USB 数据卡的功能。 由于此时 USB数据卡只有数据卡功能,此时 USB数据卡与 USB主机控制器之间的总线,在设定的时间间隔未检测到操作数据信息时, 自动挂起,该 USB数据卡进入休眠状态,从而实现了该带 U盘功能的 USB 数据卡进入休眠状态。
当本发明实施例中该带 U盘功能的数据卡进入休眠状态后, 还可以从 休眠状态唤醒。图 5为本发明实施例提供的该带 U盘功能的 USB数据卡进 入休眠状态及从休眠状态唤醒的过程, 该过程包括以下步骤:
S501 : USB数据卡在与主机枚举过程中, 将所述第一 USB数据卡配置 信息发送给所述主机。
S502: 主机接收到 USB数据卡发送的第一 USB数据卡配置信息后, 确定此时该 USB数据卡具有 U盘功能和数据卡功能。
S503: 主机判断在设定的时间长度内是否接收到对所述 USB数据卡的 操作数据信息, 当判断结果为是时, 进行步骤 S504; 否则, 进行步骤 S505。
S504:主机将该操作数据信息发送给 USB数据卡,之后进行步骤 S503。 S505: 主机向所述 USB数据卡发送配置信息切换指令, USB数据卡将 所述第二 USB数据卡配置信息发送给所述主机, 之后进入休眠状态。
S506: 接收所述主机发送的操作数据信息, 根据所述操作数据信息, 将自身从休眠状态唤醒处理所述操作数据信息。
具体的当主机 UI接收到对 USB数据卡的操作数据信息时, 将该操作 数据信息发送给 USB数据卡, USB数据卡根据该操作数据信息, 将自身从 休眠状态唤醒, 并对该操作数据信息处理。
当 USB数据卡从休眠状态唤醒后, 具体的可以根据该操作数据信息, 确定具体的向主机枚举哪种配置信息, 以便对该操作数据信息进行处理。 当判读该操作数据信息是否为对数据卡的操作数据信息; 当确定所述操作 数据信息为对数据卡的操作数据信息时, 将自身从休眠状态唤醒, 并将所 述第二 USB数据卡配置信息发送给主机, 之后处理所述操作数据信息, 否 则,将自身从休眠状态唤醒,将所述第一 USB数据卡配置信息发送给主机, 之后处理所述操作数据信息。
或者, 在本发明实施例中为了用户使用该 USB数据卡的透明性, 因为 该 USB数据卡在休眠之前, 用户使用该 USB数据卡时, 主机认为该 USB 数据卡为带 U盘功能的数据卡, 因此当该主机接收到对该 USB数据卡的操 作数据信息时,将该操作数据信息发送给 USB数据卡后,该 USB数据卡也 可以不进行判断, 直接向主机发送第一 USB数据卡配置信息, 从而增强用 户使用 USB数据卡的透明性。
图 6为本发明实施例提供的带 U盘功能的 USB数据卡进入休眠状态及 从休眠状态唤醒的详细过程, 该过程包括以下步骤:
S601 : USB数据卡在与主机枚举过程中, 将所述第一 USB数据卡配置 信息发送给所述主机。
S602: 主机接收到 USB数据卡发送的第一 USB数据卡配置信息后, 确定此时该 USB数据卡具有 U盘功能和数据卡功能。
S603: 主机判断在设定的时间长度内是否接收到对所述 USB数据卡的 操作数据信息, 当判断结果为是时, 进行步骤 S604; 否则, 进行步骤 S605。
S604:主机将该操作数据信息发送给 USB数据卡,之后进行步骤 S603。
S605: 主机向所述 USB数据卡发送配置信息切换指令, USB数据卡将 所述第二 USB数据卡配置信息发送给所述主机, 之后进入休眠状态。
S606: USB数据卡接收所述主机发送的操作数据信息。
S607: 判断所述操作数据信息是否为对数据卡的操作数据信息, 当判 断结果为是时, 进行步骤 S608; 否则, 进行步骤 S609。
S608: 将自身从休眠状态唤醒, 并将所述第二 USB数据卡配置信息发 送给所述主机, 之后处理所述操作数据信息。
S609: 将自身从休眠状态唤醒, 将所述第一 USB数据卡配置信息发送 给主机, 之后处理所述操作数据信息。
根据上述实施例可知, 在本发明实施例中当 USB数据卡接收到主机发 送的操作数据信息后, 根据该操作数据信息是对数据卡的操作数据信息, 还是对 U盘的操作数据信息, 当为对数据卡的操作数据信息时, 该 USB数 据卡将自身的第二 USB数据卡配置信息发送给主机,此时主机确定该 UBS 数据卡为不带有 U盘功能的数据卡,之后该 UBS数据卡处理该操作数据信 息即可。 当该操作数据信息是对 U盘的操作数据信息时, 该 USB数据卡的 第二 USB数据卡配置信息为不带有 U盘功能的 USB数据卡的配置信息, 因此该 USB数据卡在从休眠状态唤醒后,将自身第一 USB数据卡配置信息 发送给主机, 由于该第一 USB数据卡配置信息为具有 U盘功能和数据卡功 能的配置信息, 因此, 此时该 USB数据卡具有 U盘功能和数据卡功能, 因 该 USB数据卡对该操作数据信息进行处理。
图 7为本发明实施例提供的一种带 U盘功能的 USB数据卡进入休眠状 态的装置的结构示意图, 该装置包括:
存储模块 71 , 设置为保存第一 USB数据卡配置信息和第二 USB数据 卡配置信息,其中,所述第一 USB数据卡配置信息为具有 U盘功能的 USB 数据卡的配置信息, 第二 USB数据卡配置信息为不带 U盘功能的 USB数 据卡的配置信息;
枚举模块 72,设置为在与主机枚举过程中, 将所述第一 USB数据卡配 置信息发送给所述主机, 并根据接收切换模块的通知, 将所述第二 USB数 据卡配置信息发送给所述主机;
接收切换模块 73 ,设置为根据接收到的主机发送的配置信息切换指令, 通知枚举模块将所述第二 USB数据卡配置信息发送给所述主机;
之后所述装置进入休眠状态。
所述装置中,
所述接收切换模块 73 , 还设置为接收所述主机发送的操作数据信息; 将所述操作数据信息发送给对应数据卡, 将数据卡从休眠状态唤醒处理所 述操作数据信息。
所述接收切换模块 73 , 具体设置为判断所述操作数据信息是否为对数 据卡的操作数据信息; 当确定所述操作数据信息为对数据卡的操作数据信 息时, 将该装置从休眠状态唤醒, 通知所述枚举模块, 将该第二 USB数据 卡配置信息发送给所述主机, 否则, 通知所述枚举模块, 将所述第一 USB 数据卡配置信息发送给所述主机。
本发明实施例提供了一种带 U盘功能的 USB数据卡进入休眠状态的方 法、系统及装置,该 USB数据卡包括第一 USB数据卡配置信息和第二 USB 数据卡配置信息, 其中第一 USB数据卡配置信息为具有 U盘功能的 USB 数据卡的配置信息, 第二 USB数据卡配置信息为不带 U盘功能的 USB数 据卡的配置信息,首先 USB数据卡在与主机枚举过程中,将第一 USB数据 卡配置信息发送给主机, 当接收到主机发送的配置信息切换指令时, 将第 二 USB数据卡配置信息发送给主机, 之后进入休眠状态。 由于在本发明实 施例中该 USB数据卡中包括具有 U盘功能的 USB数据卡的配置信息, 和 不带有 U盘功能的 USB数据卡的配置信息,虽然首先枚举的为具有 U盘功 能的 USB数据卡的配置信息, 当接收到主机发送的配置信息切换指令后, 将不带 U盘功能的 USB数据卡的配置信息发送给主机,该不带 U盘功能的 USB数据卡按照 USB接口规范, 就可以自动的进入休眠状态, 从而减少了 其耗电量。
