以下结合具体的实施例说明本发明提供的数据传输方法、 装置及系 统。
本发明实施例提供了一种数据传输方法， 该方法可通过图 1所示的 应用环境实现， 用于发送端设备向接收端设备传输数据。 图 4所示为上 述方法的流程图。 请参考图 4, 本实施例的方法包括以下步骤。
步骤 Sil， 发送端设备获取一组数据包。 在本步骤中， 发送端设备获取一组待传输给接收端设备的数据包。 其中， 该组数据包包括至少一个数据包， 并且每个数据包均为无需经由 传输协议进行分割的小数据。 该组数据包中的所有数据包具有相应的序 列号。 在一个实例中， 该组数据包中的数据包的序列号可由发送端设备 分配。 例如， 发送端设备 ·依序分配序列号给该组数据包中的每一个数据 包， 该组数.据包中的每一个数据包的序列号与其它数据包序列号均不相 同。
步骤 S12, 发送端设备与接收端设备初始化至少两种传输协议并建 立对应该至少两种传输协议的至少两个传输通道。
其中， 发送端设备与接收端设备均包括多个传输协议， 且发送端设 备与接收端设备均包括至少两种相同的传输协议。 传输协议可为但不限 于 TCP、 UDP、 蓝牙 SPP等协议。
在本步骤中， 当发送端设备准备向接收端设备发送该组数 包时， 发送端设备与接收端设备初始化至少两种传输协议并建立对应该至少 两种传输协议.的至少两个传输通道， 其中， 一个传输通道对应一种传输- 协议。 举例说明， 假设发送端设备包括 l'CP、 IJDP、 蓝牙 SPP这三种传 输协议， 接收端设备也具有 TCP UDP、 蓝牙 SPP这三种传输协议， 那 么根据实际情况， 发送端设备和接收端设备可以选择 TCP、 UDP、 蓝牙 SPP这三种传输协议中的任意两种传输协议来传输数据， 建立两个传输 通道； 或者采用 TCP、 UDP、 蓝牙 SPP这三种传输协议来传输数据， 建 立三个传输通道。 当发送端设备和接收端设备同时拥有更多数量的传输 协议时， 也可采用三种以上的传输协议来传输数据， 此时需要建立更多 的传输通 i£。
步骤 S13， 发送端设备根据该至少两个传输通道的数量将该组数据 包复制成多组数 包。 在本步骤中， 发送端设备对该组数据包进行复制， 使复制后的所有 组数据包的组数等于所建立的传输通道的个数， 以使一个传输通道可以 传输一组数据包。 由于其它组的数据包是由该组数据包复制而成， 因此 同样的数据包在复制后的每组数据包中的序列号均相同。
步骤 S14, 发送端设备通过该至少两个传输通道同时传输复制后的 该多组数.据包至接收端设备， 其中， 一个传输通道传输一组数据包。
在本步驟中， 发送端设备通过该至少两个传输通道同时传输复制后 的该多组数据包至所述接收端设备， 即采用多协议同时传输的方式来传 输发送端设备先前所获取的该组数据包。 举例说明， 若发送端设备和接 收端设备之前建立了第一传输通道（如根据 TCP建立）和第二传输通道 (如根据 UDP建立）这两个传输通道， 则该多组数据包的数量为两组， 第一传输通道用来传输其中一组数据包， 而第二传输通道用来传输其中 另一组数据包。
进一步地， 该组数据包中的每个数据包的长度不大于该至少两种传 输协议各自所允许传输的无需分割的最大的数据包中长度最小的数据 包长度。 仍以上述例子进行说明， 若第一传输通道对应的第一传输协议 允许传输的无需分割的数据包长度最大为 1480 字节， 而第二传输通道 对应的第二传输协议允许传输的无需分割的数据包长度最大为 1472 字 节， 则第二传输协议允许传输的无需分割的数据包长度最小， 那么该组 数据包中的每个数据包的长度应该不大于该第二传输协议允许传输的 无需分割的最大的数据包长度， 即 1472字节。
步骤 S15 , 接收端设备预接收该至少两个传输通道传输的数据包。 在本步骤中， 当每一传输通道中的一数据包到达接收端设备时， 接 收端设备预接收该数据包。
步骤 S16， 针对相同序列号的数据包， 接收端设备接收该至少两个 传输通道传输的先到达的数据包并丢弃后到达的具有相同序列号的其 他数据包。
在本步骤中， 针对相同序列号的数据包， 所述接收端设备接收该至 少两个传输通道传输的先到达的数据包并丢弃后到达的具有相同序列 号的其他数据包， 即釆用 "先到接收、 后到丟弃" 的接收原则。 还以上 述例子进行说明， 如图 5和图 6所示， 发送端设备与接收端设备采用第 一传输通道与第二传输通道同时传输复制后的同样的两组数据包， 假设 每组数据包包括 4个数据包， 该 4个数据包的序号 SN分别为 1、 2 , 3、 4。在图 5中， 第一传输通道传输的序列号 SN二 1的数据包先到达接收端 设备，则接收端设备接收该第一传输通道传输的序列号 SN=1的数据包； 在图 6中， 第二传输通道传输的序列号 SN 1的数.据包后到达接收端设 备， 则接收端设备 ·丟弃该第一传输通道传输的序列号 SN=1的数据包。 以此类推， 当发送端设备与接收端设备采用三个以上的传输通道同时传 输同样的一组数据包时， 针对序列号相同的数据包， 接收端设备接收最 先到达的数据包， 而丢弃后到的其他序列号相同的数据包。
由此可见， 通过本实施例所提^ ^的数据传输方法， 针对同一组数据 包釆用对应多个传输协议的传输通道同时传输， 该多个协议可为但不限 于可靠型与非可靠型传输协议的结合， 可同时满足数据传输的完整性和 实时性服务需求。
请参考图 7， 图 7为本实施例的步骤 S16的主要子步骤的流程示意 图， 该步骤 S16包括以下子步骤。
步骤 S161 , 当每一传输通道中的一数据包到达.接收端设备时， 接收 端设备在预接收该数据包之后判断是否已接收具有与该数据包相同序 列号的通过另一传输通道传输的另一数据包。
在本步骤中， 接收端设备预接收每一传输通道传输的每一数据包之 后， 确认当前到达的数据包的序列号， 并判断是否已接收到与当前数据 包相同序列号的经由另一传输通道中传输的另一数据包， 若判断已接收 到该另一数据包， 则执行步骤 S162; 若判断未接收到该另一数据包， 则 执行步骤 Si 63。
步骤 S 162 , 丟弃该数据包；
在本步骤中， 若接收端设备判断已接收到与当前数据包相同序列号 的经由另一传输通道中传输的另一数据包， 则丟弃当前到达的数据包。
步骤 S 163 , 接收该数据包„
在本步骤中， 若接收端设备判断未接收到与当前数据包相同序列号 的经由另一传输通道中传输的另一数据包， 则接收该数据包。

在本步骤中， 发送端设备和接收端设备在完成该组数据包的传输之 后， 释放该至少两个传输通道。 比如， 当接收端设备接收到该组数据包 所包含的所有数据包之后， 释放该至少两个传输通道。 进一步地， 接收 端设备还发送已接收到该组数据包所包含的所有数据包的信息给发送 端设备， 当发送端设备接收到接收端设备发送的已接收到该组数据包所 包含的所有数据包的信息时， 释放该至少两个传输通道。 在本发明实施 例中， 发送端设备也可在发送完该组数据包所包含的所有数据包之后， 发送释放该至少两个传输通道的信息给接收端设备， 而接收端设备接收 到该组数.据包所包含的所有数据包之后， 发送释放该至少两个传输通道 的确认信息给发送端设备， 发送端设备收到该确认信息之后释放该至少 两个传输通道。 该至少两个传输通道的释放可以根据各自对应的传输协 议或者实际需要来进行， 并不限于上述举例的几种方式。
在本发明实施例中， 当每一传输通道中的该组数据包所包含的所有 数据包到达接收端设备之后， 可以同时或者分别释放该至少两个传输通 道； 或者， 只要接收端设备接收到该组数据包所包含的所有数据包后， 不管是否有传输通道还没有完成所有数据包的传输， 即释放该至少两个 传输通道中的所有传输通道。

在本步驟中， 当发送端设备准备向接收端设备发送该组数据包时， 发送端设备初始化至少两种传输协议并与接收端设备建立对应该至少 两种传输协议的至少两个传输通道， 其中， 一个传输通道对应一种传输 协议。 举例说明， 假设发送端设备包括 TCP、 UDP、 蓝牙 SPP这三种传 输协议， 对应地， 接收端设备也具有 TCP、 UDP、 蓝牙 SPP这三种传输 协议，那么根据实际情况，发送端设备和接收端设备可以选择 TCP、 UDP、 蓝牙 SPP这三种传输协议中的任意两种传输协议来传输数据， 建立两个 传输通道；或者采用 TCP、 UDP,蓝牙 SPP这三种传输协议来传输数据， 建立三个传输通道。 当发送端设备和接收端设备同时拥有更多数量的传 输协议时， 也可采用三种以上的传输协议来传输数据， 此时需要建立更 多的传输通道。
步骤 S33， 根据该至少两个传输通道的数量将该组数据包复制成多 组数据包。
在本步骤中， 发送端设备对该组数据包进行复制， 使复制后的所有 组数据包的组数等于所建立的传输通道的个数， 以使一个传输通道可以 传输一组数据包。 由于其它组的数.据包是由该组数.据包复制而成， 因此 同样的数据包在复制后的每组数据包中的序列号均相同。

并且， 该接收端设备可在每一传输通道中的一组数据包中的所有数 据包到达.接收端设备之后， 同时或者分别释放该至少两个传输通道； 或 者， 只要接收端设备接收到该组数据包所包含的所有数据包后， 不管是 否有传输通道还没有完成所有数据包的传输， 即释放该至少两个传输通 道中的所有传输通道。
步骤 S45 , 当接收到该组数据包所包含的所有数据包之后， 对所接 收到的所有数.据包进行整合。
在本步骤中， 当接收到该组数据包所包含的所有数据包之后， 接收 端设备对所接收到的所有数据包进行整合， 使接收到的所有数据包整合 成一组数据包或者进一步恢复成发送端设备进行分割前的数据。
本发明实施例提供一种数据传输装置，该装置可运行于发送端设备， 用于实现上述实施例中的数据传输方法。 如图 15 所示， 所述装置包括 获取模块 501、 多协议通道建立模块 503、 复制模块 504、 传输^ I块 505 以及传输通道释放模块 506。
获取模块 50】， 用于获取一组数据包。 其中， 获取模块 501获取一 组待传输给接收端设备的数据包， 该组数据包包括至少一个数据包。 每 个数据包均为无需经由传输协议进行分割的 d、数据。 该组数据包中的所 有数据包具有相应的序列号。
多协议通道建立模块 503， 用于初始化至少两种传输协议并与接收 端设备建立对应该至少两种传输协议的至少两个传输通道， 其中， 一个 传输通道对应一种传 H协 i义。
复制模块 504, 用于根据该至少两个传输通道的数量将该组数据包 复制成多组数据包， 其中， 同祥的数据包在复制后的每组数据包中的序 列号相同。
传输模块 505 , 用于通过该至少两个传输通道同时传输复制后的该 多组数据包至接收端设备， 其中， 一个传输通道传输一组数据包。 具体 地， 传输模块 505通过该至少两个传输通道同时传输复制后的该多组数 据包至所述接收端设备， 即采用多协议同时传输的方式来传输获取模块 501 所获取的该组数据包。 举例说明， 若发送端设备和接收端设备之前 建立了第一传输通道（如根据 TCP建立）和第二传输通道 (如根据 UDP 建立）这两个传输通道， 则该多组数据包的数量为两组， 第一传输通道 用来传输其中一组数据包， 而第二传输通道用来传输其中另一组数据 包。
进一步地， 该组数据包中的每个数据包的长度不大于该至少两种传 输协议各自所允许传输的无需分割的最大的数据包中长度最小的数据 包长度.。 钙以上述例子进行说明， 若第一传输通道对应的第一传输协议 允许传输的无需分割的数据包长度最大为 1480 字节， 而第二传输通道 对应的第二传输协议允许传输的无需分割的数据包长度最大为 1472 字 节， 则第二传输协议允许传输的无需分割的数据包长度最小， 那么该组 数据包中的每个数据包的长度应该不大于该第二传输^议允许传输的 无需分割的最大的数据包长度， 即 1472字节。
传输通道释放模块 506， 用于当接收到接收端设备发送的已接收到 该组数据包所包含的所有数据包的信息之后， 释放该至少两个传输通 道。 其中， 当发送端设备接收到接收端设备发送的已接收到该组数据包 所包含的所有数据包的信息之后， 传输通道释放模块 506 #放该至少两 个传输通道。 该发送端设备接收到接收端设备发送的已接收到该组数据 包所包含的所有数据包的信息之后， 传输通道释放.模块 506可以在每一 传输通道中的一组数据包中的所有数据包到达接收端设备之后， 同时或 者分别释放该至少两个传输通道； 或者， 只要接收端设备.接收到该组数 据包所包含的所有数据包后， 不管是否有传输通道还没有完成所有数据 包的传输， 传输通道译放模块 506即释放该至少两个传输通道的中的所 有传输通道
在其他实施例中， 发送端设备也可在接收到接收端设备发送的已接 收到该组数据包所包含的所有数据包的信息之后， 由传输通道.释放模块 506发送释放该至少两个传输通道的信息给接收端设备， 在进一步收到 接收端设备的确认信息之后释放该至少两个传输通道。
该至少两个传输通道的释放可以根据各自对应的传输协议或者实际 需要来进行， 并不限于上述举例的几种方式。
此外， 该数据传输装置还包括预分割模块 500, 用于预先对数据进 行分割以获取该组数据包。 其中， 分割的标准需满足该组数据包中的每 个数据包的长度不大于至少两种传输协议各自所允许传输的无需分割 的最大的数据包中长度最小的数据包长度， 且发送端设备与接收端设备 均包括该至少两种传输协议， 并通过该至少两种传输协议同时传输该组 数据包。
由此可见， 通过本实施例所提^ ^的数据传输装置， 针对同一组数据 包釆用对应多个传输协议的传输通道同时传输， 该多个协议可为但不限 于可靠型与非可靠型传输协议的结合， 可同时满足数据传输的完整性和 实时性服务需求。
本发明实施例提供一种数.据传输装置，该装置可运行于接收端设备， 用于实现上述实施例中的数据传输方法 如图 16 所示， 所述装置包括 多协议通道建立模块 601、 数据预接收模块 602、 判断模块 603、 数据接 收模块 604、 传输通道释放模块 605以及整合模块 606。
多协议通道建立模块 601 , 用于初始化至少两种传输协议并与发送 端设备建立对应该至少两种传输协议的至少两个传输通道。 其中， 当接 收端设备需要接收发送端设备发送的一组数据包时， 多协议通道建立模 块 601初始化至少两种传输 ¼、议并与发送端设备建立对应该至少两种传 输协议的至少两个传输通道， 其中， 一个传输通道对应一种传输协议。 该至少两个传输通道均用于传输同一组数据包， 该组数据包中的所有数 据包具有相应的序列号， 该组数据包预先被复制成多组， 以使一个传输 通道用于传输一组数据包， 且同样的数据包在复制后的每组数据包中的 序列号相同。
举例说明， 假设接收端设备包括 TCP、 UDP、 蓝牙 SPP这三种传输 协议， 对应地， 发送端设备也具有 TCP、 UDP、 蓝牙 SPP这三种传输协 议，那么根据实际情况，接收端设备和发送端设备可以选择 TCP UDP> 蓝牙 SPP这三种传输协议中的任意两种传输协议来传输数据，建立两个 传输通道；或者釆用 TCP、 UDP、蓝牙 SPP这三种传输协议来传输'数据， 建立三个传输通道。 当设备接收端和发送端设备同时拥有更多数量的传 输协议时， 也可采用三种以上的传输协议来传输数据， 此时需要建立更 多的传输通道。
数据预接收模块 602， 用于预接收所述发送端设备通过该至少两个 传输通道传输的数据包。 具体地， 数据预接收模块 602预接收发送端设 备通过该至少两个传输通道传输的数据包。 举例说明， 若接收端设备和 发送端设备之前建立了第一传输通道（如根据 TCP建立）和第二传输通 道（如根据 UDP 建立）这两个传输通道， 則第一传输通道用来传输该 组数据包， 而第二传输通道用来传输由该组数据包所复制的、 与该组数 据包相同的另一组数据包。 其中， 两组数据包中的同祥的数据包在的序 列号相同。
进一步地， 该组数据包中的每个数据包的长度不大于该至少两种传 输协议各自所允许传输的无需分割的最大的数据包中长度最小的数据 包长度。 仍以上述例子进行说明， 若第一传输通道对应的第一传输协议 允许传输的无需分割的数据包长度最大为 1480 字节， 而第二传输通道 对应的第二传输协议允许传输的无需分割的数据包长度最大为 1472 字 节， 则第二传输协议允许传输的无需分割的数据包长度最小， 那么该组 数据包中的每个数据包的长度应该不大于该第二传输协议允许传输的 无需分割的最大的数据包长度， 即 1472字节。
判断模块 603 , 用于当每一传输通道中的一数据包到达接收端设备 时， 在数据预接收t块 602预接收该数据包之后判断是否已接收到具有 与该数据包相同序列号的通过另一传输通道中传输的另一数据包； 若判 断已接收到该另一数据包， 则通知数据接收模块 604丢弃该数据包； 以 及若判断未接收到该另一数据包， 则通知数据接收模块 604接收该数据 包。 具体地， 数据预接收模块 602预接收每一传输通道传输的每一数据 包之后， 判断模块 603确认当前到达的数据包的序列号， 并判断是否已 接收到与当前数据包相同序列号的经由另一传输通道中传输的另一数 据包， 若判断模块 603判断已接收到与当前数据包相同序列号的经由另 一传输通道中传输的另一数据包， 则通知数据接收模块 604丟弃当前到 达的数据包； 若判断模块 603判断未接收到与当前数据包相同序列号的 经由另一传输通道中传输的另一数据包， 则通知数据接收模块 604接收 该数据包。
数据接收模块 604， 用于针对相同序列号的数据包， 接收该至少两 个传输通道传输的先到达的数据包并丢弃后到达的具有相同序列号的 其他数据包， 即采用 "先到接收、 后到丟弃" 的接收原则。
传输通道.释放模块 605 , 用于当数据接收模块 604接收到该组数据 包所包含的所有数据包之后， 释放该至少两个传输通道。 具体地， 当数 据接收模块 604接收到该组数据包所包含的所有数据包之后， 由传输通 道释放模块 605释放该至少两个传输通道。
并且， 该传输通道译放模块 605可在每一传输通道中的一组数据包 中的所有数据包到达接收端设备之后， 同时或者分别 #放该至少两个传 输通道； 或者， 只要接收端设备接收到该组数据包所包含的所有数据包 后， 不管是否有传输通道还没有完成所有数据包的传输， 该传输通道释 放模块 605即释放该至少两个传输通道中的所有传输通道。
进一步地，接收端设备还包括信息发送模块（图未示）， 该信息发送 模块用于发送已接收到该组数据包中的所有数据包的信息给发送端设 备。
整合模块 606， 用于当数据接收模块 604接收到该组数据包所包含 的所有数据包之后， 对所接收到的所有数据包进行整合， 使接收到的所 有数据包整合成一组数据包或者进一步恢复成发送端设备进行分割前 的数据。
由此可见， 通过本实施例所提供的数据传输装置， 针对同一组数据 包采用对应多个传输协议的传输通道同时传输， 该多个协议可为但不限 于可靠型与非可靠型传输^议的结合， 可同时满足数据传输的完整性和 实时性服务需求。
