本申请主张在2018年10月10日在中国提交的中国专利申请号No.201811176709.1的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，特别是指一种数据传输方法、装置及设备。
背景技术
随着技术的发展，第五代移动通信技术(the 5th generation wireless systems，5G)网络将支持多种业务和应用场景，例如具有更高带宽、更低时延的增强移动宽带(Enhanced Mobile Broadband，eMBB)业务，支持海量用户连接的物联网(Massive Machine-Type Communication，mMTC)业务，以及超高可靠性、超低时延通信(Ultra Reliable&Low Latency Communication，uRLLC)等。可以预见的是，5G时代，将会引入许多新的用户应用，例如：密集城区无处不在的高清/超高清甚至三维(three dimensional，3D)全息影片和视频、任何地方100Mbps的高速用户体验、大于350km/h的高速移动应用、传感网、触觉互联网、电子医疗E-Health、自然灾害监测等。
为满足中国移动5G网络需求，5G传输基于切片分组网(Slicing Packet Network，SPN)机制。数据通过用户网络接口(User Network Interface，UNI)进入SPN设备后，先经过数据分类，区分数据类型，进入网络节点接口NNI转发流程。
然而，相关技术中的SPN中建立基于切片的业务时，需要根据接入带宽建立端到端的分层以太网(Slicing Ethernet，SE)通道，比如接入业务均值1千兆以太网(Gigabit Ethernet，GE)峰值10GE，需要建立10GE的SE通道，3个接入点就需要3个SE通道，占用30GE的物理通道带宽，但SE通道只能被一个客户端占用，发送时SE通道内的时隙占用按照分配时隙随机占用，如1G流量进入也会占用10G的传输时隙。因此，即使带宽和时隙有空闲， 也不能和其他客户端共享带宽和时隙，带宽和时隙利用率低，业务配置不灵活。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合 附图及具体实施例进行详细描述。
本公开针对相关技术中的SPN传输中，SE通道只能被一个客户端占用，发送时SE通道内的时隙占用按照分配时隙占用，易出现带宽和时隙空闲的问题，提供了一种数据传输方法，实现SE通道的时隙化传输，有效利用空闲时隙，提高SE通道的利用率，实现业务的灵活上下和传输。
如图1所示，本公开实施例的一种数据传输方法，应用于切片分组网SPN设备，包括：
步骤101，将待传输数据通过分层以太网通道中的固定时隙传输至接收端，其中所述分层以太网通道为多业务数据传输通道。
通过上述步骤，本公开实施例的数据传输方法，会将待传输数据通过SE通道中的固定时隙来传输，这样，SPN设备的SE通道中因固定时隙来传输对应的业务数据(即同一业务的待传输数据)，对于作为多业务数据传输通道的SE通道，可便于后续利用空闲时隙传输新的业务数据，达到有效利用空闲时隙，提高SE通道的利用率的目的，实现业务的灵活上下和传输。
其中，接收端为发送该待传输数据的SPN设备的SPN子设备，也就是接收该待传输数据的SPN设备。
在该实施例中，如图2所示，在步骤101之前，所述方法还包括：
步骤102，接收传输控制设备在接收到业务数据传输申请后，发送的传输配置信息；
步骤103，根据所述传输配置信息，进行数据传输的配置。
这里，传输控制设备可为软件定义网络(Software Defined Network，SDN)控制器，该SDN控制器在接收到业务数据申请后，会为与该业务数据申请相关的SPN设备确定传输配置信息，并将该传输配置信息发送至相关的SPN设备。如此，接收到该传输配置信息后，就能够由该传输配置信息进行数据传输的配置，从而在配置完成后，实现将与该业务数据申请对应的待传输数据通过SE通道中固定时隙传输至接收端。
应该知道的是，该业务数据传输申请是业务系统针对业务需求提出的带宽申请，传输控制设备可根据该业务数据传输申请明确出传输所需的时隙。然而，为了有效利用SE通道中的空闲时隙，在步骤102之前，所述方法还包 括：
接收SPN父设备和SPN子设备发送的通道时隙信息，并发送自身的通道时隙信息至所述SPN父设备和SPN子设备；
将接收到的通道时隙信息以及自身的通道时隙信息发送至传输控制设备。
该实施例中的通道时隙信息用于表明SPN设备的当前SE通道的使用状态，SPN设备收集SPN父设备和SPN子设备发送的通道时隙信息后，可将其与自身的通道时隙信息一同发送至传输控制设备，能够使得该传输控制设备通过各个SPN设备的通道时隙信息了解到当前SE通道的使用状态，进而确定给出能够更好利用空闲时隙的传输配置信息。当然，该SPN设备也会发送自身的通道时隙信息至SPN父设备和SPN子设备。这里，SPN父设备是传输的上一节点设备，SPN子设备是传输的下一节点设备。
在该实施例中，所述传输配置信息包括分配给所述业务数据传输申请的传输时隙；
步骤103包括：
发送自身的通道时隙信息至对端SPN设备，并接收所述对端SPN设备发送的通道时隙信息；
根据所述通道时隙信息，判断时隙是否对齐；
在时隙对齐的情况下，由所述传输时隙确定传输所述待传输数据的固定时隙。
通过上述步骤，该SPN设备既能够发送自身的通道时隙信息给对端SPN设备(与该SPN设备进行数据传输的SPN设备)，也能够接收对端SPN设备发送的通道时隙信息，之后根据自身以及对端SPN设备的通道时隙信息联合判断之间的时隙是否对齐，从而在时隙对齐的情况下，由传输控制设备分配的传输时隙确定传输该待传输数据的固定时隙，以便实现接收端的SPN设备能够有效地接收到该待传输数据。
例如，对于业务数据传输申请的带宽，SDN控制器将首先得到对应该带宽的时隙数，然后结合接收到的通道时隙信息由SE通道时隙占用和空闲情况，确定为该业务分配的传输时隙，如告知SPN设备1的传输时隙为第3-5时隙，告知SPN设备2(SPN设备1传输的下一节点设备)在SPN设备1的传输时 隙即第3-5时隙上接收数据。而为了确保传输的有效性，根据所分配的传输时隙，会对传输时隙是否对齐进行判断。在时隙对齐的情况下则可由所分配的传输时隙确定传输待传输数据的固定时隙。如此，SPN设备1会按照时隙发送，到发送队列取得待传输数据填入对应的时隙第3-5时隙，然后发送到物理层的物理编码子层PCS。SPN设备2在SPN设备1的第3-5时隙接收到业务数据后，再在自己SE通道的第8-10时隙(由SDN控制器分配给SPN设备2的传输时隙)传输到下一节点设备。
当然，该实施例中还存在时隙未对齐的情况，所以，根据所述通道时隙信息，判断时隙是否对齐之后，包括：
在时隙未对齐的情况下，进行时隙校准，直至时隙对齐。
这里，对于经判断获知时隙未对齐的情况，将进行时隙校准，直至时隙对齐。其中，时隙校准是通过传输两端的SPN设备协商完成，两者会基于双方的通道时隙信息以及已分配的传输时隙，确定最终传输数据的固定时隙。当然，具体的协商原则可预先设定，在此不再一一列举。
在该实施例中，考虑到交叉规则，还存在分配的传输时隙不适配的情况，可通过预设置原则确定传输时隙。例如，为SPN设备3分配的传输时隙为第3-5时隙，为SPN设备4分配的传输时隙为第3-5时隙，但由交叉规则，SPN设备3的第3-5时隙对应SPN设备4的第2-4时隙，基于交叉规则优先，若SPN设备4的第2时隙空闲，则SPN设备4使用第2-4时隙进行传输。当然，该预设置原则不限于上述的交叉规则优先，在此不再一一列举。
可选地，所述通道时隙信息包括时隙化标识、传输使用的信道序号和当前信道的时隙图。
这样，通过时隙化标识可知是否支持时隙化，而传输使用的信道序号和当前信道的时隙图可便于了解哪些时隙被占用，哪些时隙空闲(占用为1，空闲为0)。
具体的，所述通道时隙信息携带于灵活以太网头部消息中。
如此，SPN设备传输数据，可通过灵活以太网头部消息G.mtn OH携带通道时隙信息，并通过南向接口通知SDN控制器，SDN控制器根据SE通道时隙信息来分配和管理业务传输使用的时隙。携带通道时隙信息的G.mtn OH 结构如下表1所示：
Figure PCTCN2019108886-appb-000001
表1
其中，若由通道时隙信息时隙化标识了解到SPN设备的SE通道不支持时隙化，则会在随机时隙发送接收数据。
在该实施例中，SE通道时隙化传输状态机如图3所示，SPN设备之间交互通道时隙信息，SPN设备首先会由时隙化标识来了解对端是否支持时隙化。若不支持，则在随机时隙发送接收数据。若支持，则进一步判断时隙是否对齐，在对齐的情况下，由信道序号、时隙图结合SDN控制器分配的传输时隙，在固定时隙收发数据；在未对齐的情况下，进行收发端协商直至对齐，且在协商完成后更新G.mtn OH。
综上所述，本公开实施例的数据传输方法，会将待传输数据通过SE通道中的固定时隙来传输，这样，SPN设备的SE通道中因固定时隙来传输对应的业务数据(即同一业务的待传输数据)，对于作为多业务数据传输通道的SE通道，可便于后续利用空闲时隙传输新的业务数据，达到有效利用空闲时隙，提高SE通道的利用率的目的，实现业务的灵活上下和传输。
如图4所示，本公开实施例的一种数据传输方法，应用于传输控制设备，包括：
步骤401，接收业务数据传输申请；
步骤402，根据所述业务数据传输申请以及目标SPN设备的通道时隙信息，确定所述目标SPN设备的传输配置信息并发送至所述目标SPN设备，以将待传输数据通过所述目标SPN设备的分层以太网通道中的固定时隙传输至 接收端；所述传输配置信息包括分配给所述业务数据传输申请的传输时隙。
通过上述步骤，应用本公开实施例方法的传输控制设备，在接收业务数据传输申请之后，会根据该业务数据传输申请以及目标SPN设备的通道时隙信息，确定目标SPN设备的传输配置信息并发送至目标SPN设备，以将待传输数据通过目标SPN设备的分层以太网通道中的固定时隙传输至接收端；该传输配置信息包括传输时隙。如此可实现SE通道的时隙化传输，有效利用空闲时隙，提高SE通道的利用率，实现业务的灵活上下和传输。
其中，业务数据传输申请是业务系统针对业务需求提出的带宽申请，传输控制设备可根据该业务数据传输申请明确出传输所需的时隙。目标SPN设备为该业务数据传输申请对应业务的相关SPN设备，通道时隙信息用于表明SPN设备的当前SE通道的使用状态，因此，为利用空闲时隙，会由业务数据传输申请和目标SPN设备的通道时隙信息共同确定给出能够更好利用空闲时隙的传输配置信息。当然，该传输配置信息会发送至目标SPN设备。
可选地，所述方法还包括：
接收SPN设备发送的通道时隙信息。
本步骤接收SPN设备发送的通道时隙信息，除SPN设备自身的通道时隙信息，也可包括该SPN设备的SPN父设备和SPN子设备的通道时隙信息，以便于传输控制设备结合业务的相关SPN设备的时隙状态选出适用的传输时隙。这里，SPN父设备是传输的上一节点设备，SPN子设备是传输的下一节点设备。
可选地，所述通道时隙信息包括时隙化标识、传输使用的信道序号和当前信道的时隙图。
这样，通过时隙化标识可知是否支持时隙化，而传输使用的信道序号和当前信道的时隙图可便于了解哪些时隙被占用，哪些时隙空闲(占用为1，空闲为0)。
具体的，所述通道时隙信息携带于灵活以太网头部消息中。
如此，SPN设备传输数据，可通过G.mtn OH携带通道时隙信息，并通过南向接口通知SDN控制器，SDN控制器根据SE通道时隙信息来分配和管理业务传输使用的时隙。携带通道时隙信息的G.mtn OH结构如上表1所示， 在此不再赘述。
综上，本公开实施例的数据传输方法，在接收业务数据传输申请之后，会根据该业务数据传输申请以及目标SPN设备的通道时隙信息，确定目标SPN设备的传输配置信息并发送至目标SPN设备，以将待传输数据通过目标SPN设备的分层以太网通道中的固定时隙传输至接收端；该传输配置信息包括传输时隙。如此可实现SE通道的时隙化传输，有效利用空闲时隙，提高SE通道的利用率，实现业务的灵活上下和传输。
需要说明的是，该方法是与上述应用于SPN设备的数据传输方法的配合共同实现数据传输的，上述应用于SPN设备的数据传输方法的实施例中传输控制设备侧方法的实现方式适用于该方法，也能达到相同的技术效果。
如图5所示，本公开实施例的一种SPN设备500，包括第一处理器510和第一收发器520，其中，
所述第一收发器520用于将待传输数据通过分层以太网通道中的固定时隙传输至接收端，其中所述分层以太网通道为多业务数据传输通道。
