Description

数据传输方法及相关设备
本申请要求于2021年12月31日提交中国专利局、申请号为202111664408.5、申请名称为“数据传输方法及相关设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信技术领域，尤其涉及一种数据传输方法及相关设备。
背景技术
随着信息社会的发展，终端之间的数据传输愈发的频繁和重要。通过数据传输，能够实现终端之间的互联互通、协同合作，打破信息壁垒和信息孤岛，促进数据的融合与治理，提升数据价值，推动数字经济和公共治理的发展。
现有技术中，大部分数据传输并非终端之间直接进行的，而是通过服务器进行中转的，例如，用户先将数据如视频、音乐等发送至远程服务器如业务服务器、中继服务器等，服务器再将数据转发至目标用户。
该种数据传输方式对远程服务器存在较强的依赖，例如，源终端和目标终端都必须知晓一个相同远程服务器的连接信息，二者依赖该连接信息与远程服务器建立通信连接，才能建立终端之间的数据传输通道，以进行数据传输。当远程服务器宕机或者拒绝服务时，终端不能与远程服务器建立连接，终端之间的数据传输通道断开，终端之间的数据传输将无法继续。

具体实施方式
为了更好的理解本申请的技术方案，下面结合附图对本申请实施例进行详细描述。
应当明确，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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它实施例，都属于本申请保护的范围。
在本申请实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请。在本申请实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。
现有相关技术中，数据传输依赖于传输双方根据既定的相同的连接信息连接上指定服务器，从而建立数据传输通道，以进行数据传输，该传输方式过于依赖于指定服务器，当指定服务器故障时，数据传输通道将断开，终端之间无法建立连接来进行数据传输，灵活性较差。
基于以上问题，本申请实施例提供一种数据传输方法，当终端之间进行数据 传输时，直接建立APDU链路，设备之间点对点传输操作指令，无需连接服务器来建立链路，对服务器没有依赖，传输灵活性较高。
图1是本申请实施例提出的数据传输方法的实施环境的示意图，如图1所示，实施环境包括本地端电子设备101和对端电子设备102。本地端电子设备101和对端电子设备102可以是任何可以接入网络进行传输的终端设备，例如，个人计算机，平板电脑，智能移动终端、个人数字助理、音视频播放器、、相机、游戏控制台、平板设备、智能设备、可穿戴设备、交通工具、电表、气泵、大型或小型厨房器具、健康护理设备、植入物、显示器、或任何其他类似的功能设备。
图2为本申请第一实施例提供的数据传输方法的流程图，所述方法应用于图1所示的本地端电子设备101中，如图2所示，上述数据传输方法可以包括：
步骤201，获取本地存储的身份信息，所述身份信息包括本地端身份信息和对端身份信息。
获取本地存储系统内存储的全部或者部分身份信息，所述身份信息包括了本地端电子设备身份信息和对端电子设备的身份信息。身份信息可以包括：IMSI(International Mobile Subscriber Identity，国际移动用户识别码)、临时移动用户识别码(TMSI，Temporary Mobile Subscriber Identity)，ACCID用户账号标识、国际移动设备识别码(International Mobile Equipment Identity，IMEI)、号码等。
优选的，除身份信息还获取密钥信息，所述密钥信息包括本地端电子设备的公钥、私钥及对端电子设备的公钥。
步骤202，向对端电子设备发送ADPU链路建立请求，所述请求中携带所述本地端身份信息。
将获取的本地端身份信息封装在请求指令中，该请求指令采用ADPU格式，用于向对端电子设备建立ADPU链路。
ADPU，Application Protocol data unit,应用协议数据单元，该指令由ISO国际标准化组织/IEC国际电工委员会的ISO816规范定义的。ADPU可分为命令 APDU(command APDU)和响应APDU(response APDU)。命令APDU，包含了一个必选的4字节的头部(CLA，INS，P1，P2)和数据段(0到255字节的数据)。命令APDU中，字段INS用于表示特定的命令，例如“身份验证”、“写数据”等。定义命令APDU的INS字段用来表示不同的指令，定义需要参照及GSM11.11、GSM11.14等基础协议进行，示例的，本申请实施例中的请求指令，需要采用命令APDU格式，本申请不限制该指令的INS字段的名称，其可以是任意的如Q等，本地端身份信息则被放置在指令的数据段中。
优选的，将本地端身份信息使用对端电子设备的公钥加密后再封装于APDU格式的请求指令中。
值得注意的是，本申请中涉及APDU的指令的发送及接收都采用点对点协议(Point-to-Point Protocol，PPP)进行传输，PPP(点对点)协议，在计算机网络中是用于两个路由之间直接进行的数据链路层(ISO的第2层)通信协议，中间没有任何主机或任何其他网络。它可以提供连接认证，传输加密，和数据压缩。点对点协议在互联网工程任务组(Internet Engineering Task Force)的RFC 1661协议中被指定。PPP在具体实现上有多种协议，RFC 2516协议将PPPoE(以太网点对点协议)描述为一种通过以太网实现PPP的方法，有时与DSL一起使用。RFC 2364协议规定了ATM上的点对点协议(PPPoA)，该协议描述了通过ATM适配层5(AAL5)传输PPP的方法，这也是与DSL一起使用的PPPoE的常见替代方案。
步骤203，接收所述对端电子设备发送的请求响应消息。
接收对端电子设备返回的请求响应消息，该请求响应消息的格式为响应APDU。请求响应消息是对端电子设备针对本地端电子设备发送的ADPU请求指令而返回的，具体的，对端电子设备接收到本地端电子设备发送的指令后，读取数据段中的本地端身份信息，验证所读取的信息是否为真，当读取的信息为真时，向本地端电子设备返回请求响应消息。
应当注意，该请求响应消息采用与本地端电子设备的同样的PPP(点对点)协议进行发送。
步骤204，根据本地存储的所述对端身份信息，对所述请求响应消息中携带的对端信息进行验证；
对端电子设备发送的请求响应消息，该消息为响应APDU格式，该指令中携带了对端的身份信息，读取该身份信息，验证该信息是否与本地存储系统中保存的对端身份信息相同。
优选的，当请求响应消息中的对端信息为加密状态时，使用步骤201读取的本地端电子设备私钥对该信息进行解密，以进行验证。
步骤205，当所述对端信息验证通过后，与所述对端电子设备建立应用数据单元APDU链路。
当请求响应消息中携带的对端的身份信息与本地保存的对端身份信息相同，则成功确认对端电子设备的身份，此时可以与对端电子设备建立APDU链路。
APDU链路，指的是本地端电子设备与对端电子设备之间的点对点协议连接，由于在本申请实施例中该连接上面传输的全部为APDU指令，为了便于说明将其称为APDU链路，APDU指令具有数据传输效率高，保密性强等优点。
在上述步骤201至步骤204中，本地端电子设备已经完成了一次典型的请求/响应模式，即发出请求及接收响应，该模式的完成则说明本地端电子设备完成一次与对端电子设备的通信。示例的，当对端电子设备成功接收本地端电子设备发送请求时，则说明本地端电子设备向socket(套接字)及请求信息的交付，该套接字中包括了点对点协议号、本地端电子设备的IP地址、本地端电子设备用于该端口号、目的IP地址，目的端口号，而后，对端电子设备向依据socket向本地端电子设备发送响应信息，由此，本地端电子设备完成一次与对端电子设备的PPP协议通信/连接过程。
但是在本申请实施例中，尽管收到了对端电子设备收到请求响应消息，本实 施例并不将其视为建立一个面向对端电子设备的PPP协议连接的彻底完成，而是在对请求响应消息中的对端电子设备的身份信息验证成功后，才视为完成一次完整的通信过程。本申请在当成功验证请求响应消息中的对端电子设备身份信息，说明本地端电子设备彻底完成一次与对端电子设备的PPP协议通信过程，成功在本地端电子设备和对端电子设备之间建立了一条PPP协议链路。
进一步的，在成功验证请求响应消息中的对端电子设备身份信息后，还可以借助辅助模块如net模块或者modem模块，依据该socket，将该通信固化为SendAPDU、RecieveAPDU两个专用的功能接口，以便后续调用。
在一些情况在，在APDU链路成功后，本地端电子设备还需建立监听机制，以对该链路进行监听，其中，监听的对象不仅包括对端电子设备发送的指令或数据，还包括本端需要发送的指令或数据，进而做相应执行动作。
步骤206，通过所述APDU链路向所述对端电子设备发送操作指令，所述操作指令用于指示所述对端电子设备进行操作。
本地端电子设备通过上述步骤建立的APDU链路后，通过该链路向对端电子设备发送操作指令，该操作指令也是命令APDU的格式，操作指令可用于指示所述对端电子设备进行多种操作如数据获取，操作指令用于数据获取时，同样可以在INS字段中指令一个名称来标识，其可以是任意的如G，可以在指令的数据段中则可存放用于指示对端电子设备获取待传输数据的信息，如待传输数据保存的IP地址等。
上述数据传输方法中，本地电子设备与对端电子设备之间直接建立APDU链路，点对点传输操作指令，以指示对端电子设备执行动作，与现有技术相比，本申请中设备之间的链路没有服务器参与，消息无需经过服务器进行中转，无需连接服务器就可以实现数据的传输，对服务器没有依赖，增强了数据传输的灵活性。且本申请的传输采用APDU指令，通信效率高，能够减小点对点通信的延迟，还能够增加通信的保密性。
点对点连接带来的好处是显而易见的，但是只使用点对点连接也存在一定的缺点，如，尽管使用了APDU指令，但是设备之间的延迟仍然较为明显，又如，点对点协议及APDU指令的对大文件的传输体验较差等。
图3为本申请第一实施例的一个优选实施方式的流程图，在该实施例中的实施环境如图4所示，图4示出了本申请第一实施例的一个优选实施例的实施环境，如图4所示，实施环境包括本地端电子设备101、对端电子设备102和多个共享服务器，共享服务器可以是独立的物理服务器，也可以是多个物理服务器构成的服务器集群或者分布式系统，还可以是部署在相同服务器集群中的两个独立部分或者部署在同一服务器中的独立部分如中间件服务、云计算等，每个共享服务器均设置有对应的配置信息。
如图3所示，本申请图2所示实施例中，步骤还可以包括：
步骤301，获取第一配置信息，所述第一配置信息对应第一共享服务器。
本实施例的数据传输系统中，每个共享服务器都设置有自己的对应的配置信息，配置信息是用于连接该共享服务器的，配置信息可以是APN/PDN，APN又称接入点，Access Point Name，其决定了通过哪种接入方式来访问网络，如GPRS的业务种类等，APN可视为对一个外部PDN(Public Data Network，公用数据网)的标识，配置信息在某些情况下还可以是域名、IP地址等。
本地端电子设备获取第一配置信息，第一配置信息是用于连接第一共享服务器的配置信息。
第一配置信息可以是保存在本地的或者保存在远端服务器上的，保存在本地的情况包括多种，例如沿用上一次使用过的配置信息，或者又如，预先在本地保存多个配置信息，当需要获取配置信息作为第一配置信息时，依据筛选条件如带宽最大的、空间距离最近的、延迟最低的等选择一个配置信息作为第一配置信息。
优选的，本地端电子设备除获取第一配置信息外，还获取其他配置信息，其他配置信息可以也是用于服务于数据传输链路的建立的一些信息，如账户信息、 权限信息、校验信息等，在一些示例中，其他配置信息是用户自定义或客户化个性化的配置信息。其他配置信息是否传输及内容应当视连接共享服务器的具体情况而定，例如，当共享服务器需要指定账户才能登入时，则此时就需要传输账户信息这一其他配置信息，又如，为了保证数据不丢失，可以指定加密校验算法，将其发送至对端电子设备，对端电子设备可以对接收到的配置信息和/或对数据链路上的消息进行校验。
对于第一配置信息的获取，其可以在建立ADPU链路之后进行，也可以是在步骤201中在获取身份信息时执行，本申请对此不进行限制。
步骤302，通过所述ADPU链路向所述对端电子设备发送所述第一配置信息。
本地端电子设备通过上述步骤205建立的ADPU链路，使用ADPU指令向对端电子设备发送所获取的第一配置信息，用于发送配置信息的ADPU指令被称为配置同步指令，与上述类似的，该ADPU指令为命令ADPU，不限制该指令的INS字段的名称，其可以是任意的如S等，配置信息则被放置在指令的数据段中。
对端电子设备在接收到配置同步的ADPU指令后，读取该指令中的配置信息，此时为第一配置信息，依据该配置信息建立与第一共享服务器的连接。
需要注意的是，由于命令ADPU只能存放0到255字节的数据，当配置数据、本地端身份信息较大时，可以将其拆分于多个请求指令、配置同步指令中。
优选的，配置同步指令还用于传输其他配置信息。配置同步指令除用于传输用于连接共享服务器的信息外，还用于传输其他配置信息，
配置同步指令中的数据可以是明文，也可以是使用密钥进行加密，实施非对称加密传输。
步骤303，依据所述第一配置信息连接所述第一共享服务器，以通过所述第一共享服务器建立与所述对端电子设备的数据传输链路。
本地端电子设备依据所述第一配置信息与第一共享服务器建立连接，建立该连接的协议可以是任意的如HTTP、FTP等，该协议的具体类型可以依据待传输 的数据来具体确定，以便于传输，确定过程可以是预先设置或在配置同步指令中指定。
第一共享服务器可以是由互联网运营商或者内容服务商提供的，如运营商支持bip(Bearer Independent Call Control，承载无关协议)，支持mms(Multimedia Messaging Service，多媒体短信服务)等数据业务时，通过配置信息与互联网运营商提供的第一共享服务器建立数据传输链路。
优选的，本地端电子设备与第一共享服务器成功建立连接后，调用辅助模块如net模块或者modem模块，形成SendData,RecieveData两个功能接口，以将数据传输链路固化为接口，方便调用。
数据传输链路建立成功后，本地端电子设备也可以通过建立监听机制，以对该数据链路进行监听，监听的对象不仅包括对端电子设备发送过来的数据还包括，本端电子设备自己发送的指令或数据，进而做相应执行动作。
本地端电子设备依据第一配置信息与第一共享服务器建立连接，由于对端电子设备也会依据第一配置信息建立与第一共享服务器的连接，则本地端电子设备和对端电子设备都会与第一共享服务器，即两者通过第一共享服务器建立起了另一个链路，该链路在本申请中称为数据传输链路。
步骤304，通过所述数据传输链路将共享信息传输至所述第一共享服务器以使所述第一共享服务器将所述共享信息发送给所述对端电子设备，所述共享信息为共享数据或者共享数据链接。
通过数据传输链路，本地端电子设备可以将需要向对端电子设备的共享信息发送至对端电子设备。由于数据传输链路是经由第一共享服务器建立的，则共享信息的路由应当是：本地端电子设备将共享信息发送至第一共享服务器，第一共享服务器接收到数据后将共享信息转发至对端电子设备。本实施例中，共享信息可以是共享数据如音视频等，也可以是用于获取共享数据的连接如域名等。
优选的，在本申请的一些实施例中，ADPU链路除用于传输操作指令及配置 信息外，还可以用于传输少量的媒体数据，例如，在服务器异常时，ADPU链可临时备用承载一些数据内容。
进一步的，步骤206中的所述操作指令包括以下至少一者：
对所述共享信息的控制指令、对所述对端电子设备的设置指令。
本实施例中，操作指令不只一种，还可以设定多种操作指令进行扩展，使其满足多种需要。示例的，设置一种共享信息控制指令，该指令用于控制共享信息，如当指定对共享信息进行编解码的多媒体模块，以对其播放，或，指定共享信息交给第三方应用嵌入其功能中做受控播放，或者，指定对端电子设备通过共享数据连接获取数据等。另一种示例中，设置一种设备设置指令，该指令用于对对端电子设备进行设置，如更改对端电子设备的系统某个媒体配置。
本实施例中，本地端电子设备和对端电子设备之间除建立ADPU链路外，还通过ADPU链路同步服务器的配置信息，通过服务器在设备之间建立数据传输链路，增强了数据传输能力，设备之间能够实现不同体量的传输。同时，与现有技术相比，本实施例的本地端电子设备和对端电子设备存在ADPU和数据传输两种链路，当服务器故障时，设备之间并不会彻底断开连接，部分数据仍可以通过ADPU链路传输，且仅需利用ADPU链路重新传递配置信息，就能实现更换为新的服务器，重新建立数据链路，本申请对服务器依赖程度较低，提高了数据传输的灵活性。
图6为本申请第一实施例提供的另一个优选实施方式的流程图，本实施例中的实施环境如图5所示，实施环境包括本地端电子设备101、对端电子设备102、多个共享服务器和共享服务器管理平台501，所述共享服务器管理平台501与所述本地端电子设备101存在通信连接，当依据所述第一配置信息连接所述第一共享服务器失败时，如图6所示，本申请图3所示实施例中，步骤303之后，还可以包括：
步骤601，向共享服务器管理平台发送配置更新请求。
当本地端电子设备依据所述第一配置信息连接所述第一共享服务器失败时，说明配置信息有误或者服务器失去连接，此时需要更换配置信息，连接新的服务器，以通过新的服务器建立数据传输链路。
对于本地端电子设备不保存有配置信息或者仅保存有一个配置信息的情况下，本地端电子设备可以向共享服务器管理平台请求新的配置信息，本实施例中将该新的配置信息称为第二配置信息。对于本地端电子设备与共享服务器管理平台之间的通信方式，其可以是任意的，如HTTP、UDP等，本申请对此没有限制。
共享服务器管理平台内保存有多个共享服务器对应的配置信息，共享服务器管理平台可以是独立的物理服务器，也可以是多个物理服务器构成的服务器集群或者分布式系统，还可以是部署在相同服务器集群中的两个独立部分或者部署在同一服务器中的独立部分如中间件服务、云计算等。
步骤602，接收所述共享服务器管理平台发送的更新响应消息，获取所述更新响应消息中的第二配置信息，所述第二配置信息对应第二共享服务器。
共享服务器管理平台接收到本地端电子设备发送的配置更新请求后，从管理平台内保存的配置信息选取一个作为第二配置信息，选择的方式，可以是任意的，如随机选取、按照共享服务器的带宽、按照共享服务器的延迟等。
共享服务器管理平台完成第二配置信息的选取后，向本地端电子设备发送更新响应消息，该更新响应消息携带第二配置消息。
本地端电子设备接收到更新响应消息后，获取该消息携带第二配置消息。
步骤603，通过所述ADPU链路向所述对端电子设备发送所述第二配置数据。
获取到新的配置信息后，即获取到第二配置信息后，本地端电子设备通过ADPU链路发送配置同步指令，以向对端电子设备同步所获取的第二配置信息，该步骤中的配置同步指令的数据段封装的是第二配置数据。
步骤604，依据所述第二配置信息连接所述第二共享服务器，以通过所述第二共享服务器建立与所述对端电子设备的数据传输链路。
本地端电子设备依据第二配置信息与第二共享服务器建立连接，该步骤可参照上述303执行。
本地端电子设备与第二共享服务器建立连接，由于对端电子设备也会依据第二配置信息建立与第二共享服务器的连接，则本地端电子设备和对端电子设备两者通过第二共享服务器建立起了数据传输链路。
步骤605，通过所述数据传输链路将共享信息传输至所述第二共享服务器以使所述第二共享服务器将所述共享信息发送给所述对端电子设备，所述共享信息为共享数据或者共享数据链接。
由于本实施例中的数据传输链路是经由第二共享服务器建立的，则共享信息的路由应当是：本地端电子设备将共享信息发送至第二共享服务器，第二共享服务器接收到数据后将共享信息转发至对端电子设备。本实施例中，共享信息可以是共享数据如音视频等，也可以是用于获取共享数据的连接如域名等。
图7为本申请第一实施例提供的再一个优选实施方式的流程图，在该实施例中，所述本地端电子设备在本地存储有第三配置信息，所述第三配置信息对应第三共享服务器，当通过所述第一配置信息连接所述第一共享服务器失败时，所述方法还包括：
步骤701，获取所述第三配置信息，通过所述ADPU链路向所述对端电子设备发送所述三配置数据；
当本地端电子设备除第一配置信息外还保存有一个或者多个配置信息的情况下，本地端电子设备可以向在本地选择新的配置信息，除第一配置信息外的配置信息，本实施例中将该新的配置信息称为第三配置信息。
获取到新的配置信息后，即获取到第三配置信息后，本地端电子设备通过ADPU链路发送配置同步指令，以向对端电子设备同步所获取的第三配置信息，该步骤中的配置同步指令的数据段封装的是第三配置数据。
步骤702，依据所述第三配置信息连接所述第三共享服务器，以通过所述第 三共享服务器建立与所述对端电子设备的数据传输链路；
本地端电子设备依据第三配置信息与第三共享服务器建立连接，该步骤可参照上述步骤303执行。
与步骤303类似的，由于本地端电子设备和对端电子设备都会依据第二配置信息建立与第三共享服务器的连接，则本地端电子设备和对端电子设备两者通过第三共享服务器建立起了数据传输链路。
步骤703，通过所述数据传输链路将共享信息传输至所述第三共享服务器以使所述第三共享服务器将所述共享信息发送给所述对端电子设备，所述共享信息为共享数据或者共享数据链接。
由于本实施例中的数据传输链路是经由第三共享服务器建立的，则共享信息的路由应当是：本地端电子设备将共享信息发送至第三共享服务器，第三共享服务器接收到数据后将共享信息转发至对端电子设备。本实施例中，共享信息可以是共享数据如音视频等，也可以是用于获取共享数据的连接如域名等。
上述对本说明书特定实施例进行了描述。其它实施例在所附权利要求书的范围内。在一些情况下，在权利要求书中记载的动作或步骤可以按照不同于实施例中的顺序来执行并且仍然可以实现期望的结果。另外，在附图中描绘的过程不一定要求示出的特定顺序或者连续顺序才能实现期望的结果。在某些实施方式中，多任务处理和并行处理也是可以的或者可能是有利的。
图8为本申请第二实施例提供的数据传输方法的流程图，所述方法应用于图1所示的数据传输系统中的对端电子设备102，如图8所示，上述数据传输方法可以包括：
步骤801，接收ADPU链路建立请求，对所述ADPU链路建立请求中携带的所述本地端电子设备对应的本地端身份信息进行验证；
对端电子设备接收本地端电子设备所发送的请求指令，该请求指令的格式为命令ADPU，该指令用于向对端电子设备请求建立ADPU链路。
接收到请求指令后，获取该指令中携带的身份信息，该身份信息是本地端电子设备内保存的自己的身份信息，对端电子设备对所获取的身份信息进行验证。
所述请求指令是通过PPP(点对点)协议进行发送至对端电子设备的，本申请中涉及APDU的指令的发送及接收都采用点对点协议(Point-to-Point Protocol，PPP)进行传输。
进一步的，步骤801还可以包括：
步骤11，接收所述ADPU链路建立请求，获取本地存储的身份信息，所述本地存储的身份信息包括所述本地端电子设备的身份信息；
接收到本地端电子设备所发送的请求指令后，获取本地存储系统内存储本地端电子设备身份信息，身份信息可以包括：IMSI(International Mobile Subscriber Identity，国际移动用户识别码)、临时移动用户识别码(TMSI，Temporary Mobile Subscriber Identity，ACCID用户账号标识、国际移动设备识别码(International Mobile Equipment Identity，IMEI)、号码等。
优选的，接收到本地端电子设备所发送的请求指令后，从本地存储系统内获取的信息不仅包括本地端电子设备身份信息，还包括对端电子设备身份信息。
在请求指令中携带的数据为密文或者约定进行加密通信的情况下，还需从本地存储系统内获取密钥信息，所述密钥信息包括对端电子设备的公钥、私钥及本地端电子设备的公钥。
使用对端电子设备的私钥解密请求指令中数据段的密文，以获取请求指令中携带的本地端身份信息。
步骤12，根据本地存储的所述本地端电子设备的身份信息，对所述ADPU链路建立请求中携带的所述本地端电子设备对应的本地端身份信息进行验证。
在本地存储系统中完成身份信息的获取后，依据本地存储系统内存储的本地端电子设备的身份信息验证，对请求指令中携带的身份信息验证。
步骤802，当所述本地端身份信息验证通过后，向所述本地端电子设备发送 所述ADPU请求的响应消息，以建立ADPU链路，所述响应消息中携带有所述对端电子设备的身份信息。
当本地端身份信息验证通过，例如，当请求指令中携带的本地端身份信息与本地存储系统内存储的本地端电子设备身份信息一致时，则验证通过。验证通过表明对端电子设备成功确认发送请求指令的设备为本地端电子设备。
本地端身份信息验证成功后，对端电子设备向本地端电子设备发送响应消息，所述响应消息时针对请求指令所发送，格式为响应APDU，响应APDU构造如下(Response data，SW1-SW2)，包含了Response data响应数据(0到256字节的数据)和SW1-SW2响应后缀(为必选的2字节的状态字)，响应后缀能够表示命令处理状态，如90 00(十六进制)表示成功。
响应消息中的数据段携带对端电子设备的身份信息，以使供本地端电子设备确认发送该响应消息的设备的身份，确认该设备是否为对端电子设备。当本地端电子设备确认身份信息正确后，作为通信的发起方，其完成一次请求/响应模式，实现与对端电子设备通信，与对端电子设备建立ADPU链路。
同样的，响应消息中的数据段携带对端电子设备的身份信息可以是明文，也可以是密文，例如，在请求指令中携带的数据为密文或者约定进行加密通信的情况下，使用本地端电子设备的公钥加密对端电子设备的身份信息，将该密文封装在响应消息中的数据段中。
本地端身份信息验证通过后，对端电子设备建立与本地端电子设备的APDU链路，该链路是指对端电子设备与本地端电子设备之间的点对点协议链路/连接，由于在本申请实施例中该链路仅用于传输APDU指令，为了便于说明将其称为APDU链路，APDU指令具有数据传输效率高，保密性强等优点。
实际上，对端电子设备接收请求指令时，其就已经完成了一次点对点协议通信，同步了通信所需的状态信息如二者都实例化了一个相同的socket，该状态信息，表明对端电子设备与本地端电子设备能够进行点对点协议通信连接，建立了 通信链路。
但在本实施例中，本申请中对端电子设备不将接收请求指令视为通信连接的彻底完成，还需进一步验证本地端身份信息，在本地端身份信息验证通过后，才视为一次连接的彻底完成，对端电子设备成功与本地端电子设备通信连接。
值得注意的是，本实施例中对端电子设备是默认自己就是正确的对端，本地端电子设备将成功确认应消息中携带的身份信息，因而，对端电子设备在本地端身份信息验证通过后，就可以视为连接建立成功。当然，本申请一些实施例中，默认自己就是正确的对端，在本地端身份信息验证通过后，不视为一次连接的完成，只有在接收到本地端电子设备返回的验证成功消息，才视为连接完成，二者成功建立连接。
可选的，对端电子设备建立ADPU链路后，即在成功验证请求响应消息中的对端电子设备身份信息后，还可以借助辅助模块如net模块或者modem模块，依据该socket，将该通信固化为SendAPDU、RecieveAPDU两个专用的功能接口，以便后续调用。
步骤803，接收所述本地端电子设备通过所述APDU链路发送的操作指令，依据所述操作指令进行操作。
对端电子设备接收本端电子设备通过APDU链路发送的操作指令，操作指令可用于指示对端电子设备进行多种操作如数据获取等，例如，可以定义一个数据获取的操作指令，该指令的INS字段中指定一个名称可以是任意的如G，该指令的数据段中则可存放用于指示对端电子设备获取待传输数据的信息，如待传输数据保存的IP地址等。
优选的，在APDU链路成功后，对端电子设备通过建立监听机制，以对该APDU链路进行监听，其中，监听的对象不仅包括本端电子设备发送的指令或数据，还包括对端电子设备自己需要发送的指令或数据，进而做相应执行动作。
上述数据传输方法中，本地电子设备与对端电子设备之间直接建立APDU链 路，点对点传输操作指令，以指示对端电子设备执行动作，与现有技术相比，本申请中设备之间的链路没有服务器参与，消息无需经过服务器进行中转，无需连接服务器就可以实现数据的传输，对服务器没有依赖，增强了数据传输的灵活性。且本申请的传输采用APDU指令，通信效率高，能够减小点对点通信的延迟，还能够增加通信的保密性。
图9为本申请第二实施例的一个优选实施方式的流程图，本实施例中的实施环境如图4所示，数据传输系统包括本地端电子设备101、对端电子设备102和多个共享服务器，如图9所示，本申请图8所示实施例中，步骤还可以包括：

由于本地端电子设备也会依据第一配置信息建立与第一共享服务器的连接，则对端电子设备和本地端电子设备都会与第一共享服务器连接，即两者通过第一共享服务器建立起了另一个链路，该链路在本申请中称为数据传输链路。
可选的，对端电子设备建立与共享服务器的链路后，还可以借助辅助模块如net模块或者modem模块，将该链路固化为SendData,RecieveData两个专用的功能接口，以便后续调用。
可选的，对端电子设备通过建立监听机制，以对该数据传输链路进行监听，其中，监听的对象不仅包括本端电子设备发送的指令或数据，还包括对端电子设 备自己需要发送的指令或数据，进而做相应执行动作。
步骤903，通过所述数据传输链路接收所述本地端电子设备通过所述第一共享服务器中转的共享信息，所述共享信息为共享数据或者共享数据链接。
通过数据传输链路，对端电子设备接收第一共享服务器发送的共享信息，该共享信息是由本地端电子设备的发送至第一共享服务器，第一共享服务器再中转发送的，本实施例中，共享信息可以是共享数据如音视频等，也可以是用于获取共享数据的连接如域名等。
进一步的，步骤803中的所述操作指令包括以下至少一者：
对所述共享信息的控制指令、对所述对端电子设备的设置指令。
本实施例中，操作指令可以是多种，设定多种操作指令，扩展操作指令的应用范围，满足多种需要。
示例的，设置一种共享信息控制指令，该指令用于控制共享信息，如当指定对共享信息进行编解码的多媒体模块，以对其播放，或，指定共享信息交给第三方应用嵌入其功能中做受控播放，或者，指定对端电子设备通过共享数据连接获取数据等。另一种示例中，设置一种设备设置指令，该指令用于对对端电子设备进行设置，如更改对端电子设备的系统某个媒体配置。
本实施例中，本地端电子设备和对端电子设备之间除建立ADPU链路外，还通过ADPU链路同步服务器的配置信息，通过服务器在设备之间建立数据传输链路，增强了数据传输能力，设备之间能够实现不同体量的传输。同时，与现有技术相比，本实施例的本地端电子设备和对端电子设备存在ADPU和数据传输两种链路，当服务器故障时，设备之间并不会彻底断开连接，部分数据仍可以通过ADPU链路传输，且仅需利用ADPU链路重新传递配置信息，就能实现更换为新的服务器，重新建立数据链路，本申请对服务器依赖程度较低，提高了数据传输的灵活性。

步骤A，接收所述本地端电子设备通过所述ADPU链路向发送第二配置数据，所述第二配置数据对应第二共享服务器；
