Description

能力确定方法、能力配置方法、主机、终端设备及系统 技术领域
本发明涉及终端设备，特别涉及一种终端设备的能力确定方法、终端设备的能力配置方法、主机、终端设备及终端设备的配置系统。
背景技术
通常情况下，多功能设备,比如通用串行总线(USB,Universal Serial Bus)设备,是按照默认的功能(比如功能1)模式工作，当满足一定条件后(比如安装了功能2的驱动)，则该多功能设备切换为功能2模式，并以功能2的模式工作。其中，常见的多功能设备，比如USB 3G上网卡，默认工作模式时以USB虚拟光盘方式工作，当用户安装了光盘驱动程序后，则以调制解调器(modem)或者网卡的方式工作。但是，在每次使用时，需要进行一次USB的重新枚举(即查找)，降低了用户体验。
基于此，通常使用多个配置(Multi configuration)来实现多功能的选择。也就是说，USB设备存在多个配置(Configuration)，每个Configuration实现不同的功能，比如C1：Modem；C2：网络适配器(Net Adapter)；C3：全球定位系统(GPS，Global Positioning System)等，主机(Host)通过设置不同的配置让USB设备工作在不同的功能模式下。
但是现有的实现方式中，由于主机支持的能力与USB设备支持的能力不完全相同，主机不能自动依据自身支持的能力或者USB设备的能力进行配置，从而降低了用户体验。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整的描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1，图1为本发明实施例提供的一种终端设备的能力确定方法的流程图，所述方法包括：
步骤101：主机获取终端设备支持的能力；
在该步骤中，当终端设备连接到主机(Host)上时，该终端设备通过描述符(或USE描述符)将MS_COMP_ID和MS SUBCOMP_ID发送给主机，主机在接收到描述符后，通过MS_COMP_ID启动对应的驱动，并通过所述驱动对所述MS SUBCOMP_ID进行解析，得到将该终端设备支持的能力。其中，MS_COMP_ID和MS SUBCOMP_ID均是MS_OS_Descripter中定义的专有名称，在此不再详细描述。
本实施例的终端设备以USB设备为例来说明，但并不限于此，该实施例中，USB设备具体下述功能特征：
在USB设备上通常有一个USB接口，USB设备通过该USB接口与主机连接，该USB设备上可以存储MS_COMP_ID和MS_SUBCOMP_ID，比如USB\MS_COMP_TEST&MS_SUBCOMP_ID，斜体字部分由USB设备决定的，当然，该USB设备也可以在接收到主机发送的命令后，根据该命令生成对应的MS_COMP_ID和MS_SUBCOMP_ID。其中，TEST为驱动匹配关键字，以便于主机在接收到MS_COMP_TEST后，根据TEST匹配对应的特殊驱动，该特殊驱动的作用是解析MS_SUBCOMP_ID，得带终端设备所支持的能力；SUBCOMP_ID为一个位变换(BIT MAP)数字对应的字符串，BIT MAP中每一位代表一个当前设备所支持的功能，如：
0001h：调制解调器(Modem)；
0010h：网络适配器(Net Adapter)；
0100h:全球定位系统(GPS，Global Position System)；
1000h:比特流(BT，BitTorrent)。
如果SUB COMP的值为0xD(1101)，则代表当前的USB设备可以同时支持Modem和GPS和BT。
之后，HOST可以通过接收到的所述MS_COMP_ID匹配对应的特殊驱动，通过该特殊驱动对接收到的所述MS SUBCOMP_ID进行解析，得到当前USB设备的能力，比如，当USB设备的能力为5时，表示USB设备同时支持Modem、GPS和BT等。
需要说明的是，本实施例中，TEST与USB接口对应，而USB接口除了对应特殊驱动，还可以对应其他的驱动，本实施例不作限制。
步骤102：主机根据所述终端设备支持的能力与所述主机支持的能力，确定所述终端设备和主机均支持的能力，并将所述终端设备和主机均支持的能力作为重叠能力；所述重叠能力用于所述终端设备进行能力的配置；
该步骤中，一种确定方式为：主机把USB设备支持的能力与自身所支持的能力进行与运算，得到主机和USB设备均能支持的能力，本实施例中将所述主机和USB设备均能支持的能力称为重叠能力。需要说明的是，确定所述重叠能力的方式并不限于此与运算，还可以通过其他的运算方式，本实施例不作限制。
比如Host驱动只支持Modem和BT，而USB设备同时支持Modem、GPS和BT，那么与运算的结果就是0x9(1001)，表示Host和USB设备均能同时支持Modem和BT。
步骤103：将所述重叠能力发送给所述终端设备。
该步骤中，Host驱动把与运算后得到的重叠能力发给USB设备，以便于所述终端设备对所述重叠能力进行配置。
可选的，在该实施例中，主机可以通过USB厂商(USB Vendor)自定义的命令将与运算后得到的重叠能力发送给USB设备，USB设备根据该命令进行所述重叠能力的配置，并在配置成功后，向Host发送配置成功的消息。
本发明实施例中，主机先获取终端设备所有支持的能力，然后确定与终端设备均支持的能力(即重叠能力)，并将该重叠能力告知终端设备，以便于该终端设备对重叠能力进行配置。也就是说，当主机与终端设备(比如USB设备)支持的能力不完全相同时，主机与终端设备进行功能协商，找出二者均支持的功能进行配置，从而实现了依据自身支持的能力对终端设备进行灵活配置，同时也提高了用户体验。
还请参阅图2，图2为本发明实施例提供的一种终端设备的能力确定方法的另一 流程图，所述方法包括：
步骤201至步骤203详见步骤101至步骤103；
步骤204：在接收到所述终端设备发送的配置成功的消息时，枚举出所述终端设备中配置所述重叠能力的至少一个子设备；
主机在接收到配置USB设备发送的配置成功消息时，按照所述重叠能力枚举出至少一个子设备(即USB设备按照逻辑划分的虚拟设备，本文中称为子设备)。比如，如与运算得到的重叠能力为0x9，则主机可以枚举出两个子设备，一个是Modem，一个是BT，也可以枚举出其中的一个子设备，本实施例不作限制。
步骤205：对所述至少一个子设备进行驱动加载，以使所述至少一个子设备实现所述重叠能力对应的功能。
该步骤中，如果主机枚举出两个子设备，则对这两个子设备进行驱动加载，驱动加载完成后，这两个子设备自身具有所述重叠能力对应的功能。
本发明实施例中，主机先确定与终端设备均支持的能力(即重叠能力)，并将该重叠能力告知终端设备，以便于该终端设备对重叠能力进行配置，之后，主机枚举出配置所述重叠能力的至少一个子设备，对所述至少一个子设备进行驱动加载，以使该至少一个子设备具有重叠能力对应的功能。也就是说，当主机与终端设备(比如USB设备)支持的能力不完全相同时，主机与终端设备进行功能协商，找出二者均支持的功能进行配置以及驱动加载，减少终端设备的枚举次数，提高了用户体验。同时也实现了通过不同驱动来满足不同终端设备的需求。
还请参阅图3，图3为本发明实施例提供的一种终端设备的能力配置方法的流程图，所述方法包括：
步骤301：终端设备将自身支持的能力发送给主机；
该步骤中，终端设备以USB设备为例，当并不限于此，所述USB设备将自身支持的能力发送给主机，以便于主机在接收到USB设备支持的能力后，根据自身的能力与USB设备支持的能力，确定二者均支持的能力，本实施例中，将二者均支持的能力称为重叠能力。之后，主机将该确定的重叠能力发送给终端设备。
其中，主机可以通过与运算来确定主机与USB设备均支持的能力，但并不限于此，还可以通过其他类似的计算方法来确定主机与USB设备均支持的能力。
可选的，在该实施例中，终端设备在连接到主机后，通过描述符将MS_COMP_ID和MS SUBCOMP_ID发送给主机，该主机在接收到该描述符后，驱动将与MS_COMP_ID对应的驱动，并通过该驱动对MS SUBCOMP_ID进行解析后，得到所述USB设备支持的能力。
步骤302：所述终端设备接收所述主机发送的重叠能力，所述重叠能力为所述主机根据所述终端设备支持的能力与所述主机支持的能力，确定的所述终端设备和主机均支持的能力；
可选的，该步骤中，终端设备可以通过厂商自定义的命令接收所述主机发送的所述主机与所述终端设备均支持的重叠能力。
步骤303：所述终端设备按照所述重叠能力进行配置。
终端设备将所述重叠能力对应的功能配置到对应的至少一个子设备上。
可选的，该终端设备在按照所述重叠能力进行参数配置后，将配置成功的消息发送给主机，以便于主机枚举出所述终端设备上配置所述重叠能力的至少一个子设备，并对所述至少一个子设备进行驱动加载，使所述至少一个子设备实现所述重叠能力对应的功能。
本发明实施例中，终端设备(比如USB设备)，先将自身支持的能力告知主机，以便于主机确定其与终端设备均支持的能力(即重叠能力)，并将该重叠能力告知终端设备，以便于终端设备配置该重叠的能力。也就是说，当主机与终端设备支持的能力不完全相同时，主机与终端设备进行功能协商，找出二者均支持的能力告知终端设备，以便于终端设备进行对应的配置。即主机可以根据主机的能力和终端设备的能力进行灵活配置终端设备的功能。
还请参阅图4，图4为本发明实施例提供的一种终端设备的能力配置方法的另一流程图，所述方法包括：
步骤401至步骤403详见步骤301至步骤303；
步骤404：所述终端设备将配置成功的消息发送给所述主机，以便于所述主机枚举出所述终端设备上配置所述重叠能力的至少一个子设备，并对所述至少一个子设备进行驱动加载，使所述至少一个子设备实现重叠能力对应的功能。
该步骤中，终端设备进行重叠能力的相应配置后，反馈Host一个配置成功消息， 而Host收到这个配置成功消息后，会根据与运算的结果，枚举出该终端设备中对应的至少一个子设备，如与运算的结果为0x9，则枚举出两个子设备，一个是Modem，一个是BT。之后，主机为两个子设备进行的驱动加载，从而使加载驱动的这两个子设备具有重叠能力的相关功能。
本发明实施例中，终端设备(比如USB设备)，先将自身支持的能力告知主机，以便于主机确定其与终端设备均支持的能力(即重叠能力)，并将该重叠能力告知终端设备，以便于终端设备配置该重叠的能力，然后，主机就可以枚举出配置该重叠能力的子设备，并为该子设备安装驱动。也就是说，当主机与终端设备支持的能力不完全相同时，主机与终端设备进行功能协商，找出二者均支持的能力进行配置以及驱动的加载，不但减少了枚举的次数，还提高了用户体验。同时主机也可以根据主机的能力和终端设备的能力灵活配置终端设备的功能。
同时，本发明实施例中，可以很方便的使用一个USB设备，通过提供不同的Host驱动来满足不同用户的需求，这样就可以减少USB设备厂商的开发工作。另外，设备厂商还可以用一个驱动支持所有的USB设备，降低了Host驱动的开发认证成本。

驱动二的能力值为0x01(只需要Modem)；
驱动三的能力值为0x06(需要Net Adapter和BT)。
主机与USB设备进行能力协商，确定出主机和USB设备分别满足三种不同客户的 需求，然后分别为这三种客户提供驱动。
本发明实施例中，设备厂商只需要生产一种USB设备，然后根据用户类型，给用户提供不同的Host驱动，即可满足用户的需求。
本发明应用实例二：
USB厂商只提供一个Host驱动，但是要支持这个厂商的全部USB产品。
定义功能码：
00000001(0x01)：modem
00000010(0x02)：NetAdapter
00000100(0x04)：GPS
00001000(0x08)：BT
00010000(0x10)：SD
驱动一的能力值为0x1F，即支持全部的端口。
USB设备一的能力：USB\MS_COMP_HUAWEI&MS_SUBCOMP_01，只有Modem
USB设备二的能力：USB\MS_COMP_HUAWEI&MS_SUBCOMP_11，有Modem+SD
…………
这样，设备厂商可以用一个驱动支持所有的USB设备，降低了Host驱动的开发认证成本。
本发明实施例可以根据Host支持的能力和USB设备支持的能力灵活配置USB功能，从而满足不同用户需求，提高了用户满意度。
需要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种 过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到本发明可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品可以存储在存储介质中，如ROM/RAM、磁碟、光盘等，包括若干指令用以使得一台计算机设备(可以是个人计算机，服务器，或者网络设备等)执行本发明各个实施例或者实施例的某些部分所述的方法。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以作出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
