Description

一种数据传输系统、方法、装置及计算机可读存储介质
相关申请的交叉引用
本申请基于申请号为201611010022.1、申请日为2016年11月16日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及通信技术领域，尤其涉及一种数据传输系统、方法、装置及计算机可读存储介质。
背景技术
随着无线通信设备种类和数量的快速增长，日益丰富的无线应用业务对无线网络的吞吐量、数据传输速率及时延提出了更高的要求，正是在这种背景下，长期演进第5代(Long Time Evolution 5Generation，LTE 5G)移动通信标准应运而生。
如图1所示，相关技术的LTE架构由核心网(Evolved Packet Core，EPC)和接入网(Evolved UMTS Terrestrial Radio Access Network，E-UTRAN)组成。其中，EPC包括多个逻辑节点，如服务网关(Serving GateWay，SGW)等，而E-UTRAN由多个基站(Evolved Node B，eNB)支撑。eNB与EPC之间通过S1接口进行通信，传递用户数据与信令，eNB之间通过X2接口进行通信，交互信息。如图2所示，eNB的无线侧数据主要通过无线网络层和传输网络层进行传递，eNB与eNB/EPC之间的数据传递需要预先手动建立数据传输通道，并预留带宽，如果建立的数据通道中没有数据传递，则会造成带宽资源浪费，而这些数据传输通道一旦建立就不易拆除，灵活 性比较差。此外，在TD-LTE传输网络层网中，eNB之间传送的数据全部通过L3分组传输网(Packet Transport Network，PTN)设备在本地网内疏通，具体地，对eNB之间传送的数据按照接入层→汇聚层→核心层→汇聚层→接入层的方式进行传递，这种方式不但会导致eNB之间的互联时延比较大，而且会占用汇聚层和接入层较多带宽资源。
目前，针对4G+以及以后的5G、6G时代，一些如LTE跨基站载波聚合、移动边缘计算(Mobile Edge Computing，MEC)等新兴业务对无线网络的灵活性、以及带宽都提出了更高、更苛刻的要求，而现有传输网络层的连接方式远远不能满足这些业务需求。可见，现有的无线网络数据传输方式存在着灵活性差、对带宽资源利用率低的问题。

具体实施方式
软件定义网络(Software Defined Network，SDN)是由美国斯坦福大学clean slate研究组提出的一种新型网络创新架构，其核心技术OpenFlow通过将网络设备控制面与数据面分离，从而实现了对网络中数据流量的灵活控制，为核心网络的应用创新提供了良好的平台。如果将SDN与相关技术传输网络中的PTN结合起来，就形成了软件定义分组传送网络(Software Packet Transport Network，SPTN)，SPTN是PTN的演进和升级，它可以通过开放性的应用和服务，进一步增强网络资源的智能化调度能力、扁平化客户与网络资源之间的关系，从而提升运维管理和业务运营效率，本申请正是基于这一思想提出的。
本申请对相关技术的网络架构进行了改进，增加了无线侧管理控制器、传输侧上层控制器，以及多个传输侧下层控制器。其中，无线侧管理控制器可以监测多个基站的通信需求，并且可以对多个基站的通信需求进行分析，确定出基站与基站，或者基站与EPC实体之间最优的互联方案，进一步地，将确定出的最优的互联方案信息发送给传输侧上层控制器，传输侧上层控制器可以基于接收的互联方案信息，和多个传输侧下层控制器上报的自身管辖范围内传输网元的网络拓扑结构，与传输侧下层控制器一起确 定基站或者基站与EPC实体之间的数据传输路径。
本申请实施例中，当第一网络侧节点需要与第二网络侧节点进行数据传输时，可以向无线侧管理控制器发送第一互连信令，无线侧管理控制器可以基于接收的第一互联信令，向传输侧上层控制器发送第一互连指示信息，进一步地，传输侧上层控制器在接收到第一互连指示信息之后，可以确定第一网络侧节点与第二网络侧节点之间的数据传输路径，这样，第一网络侧节点与第二网络侧节点之间的数据传输路径可以由传输侧上层控制器基于无线侧管理控制器发送的第一互连指示信息来确定，并且该数据传输路径的建立不需要人工干预，更加灵活，此外，传输侧上层控制器在确定该数据传输路径时，还可以考虑已有的数据传输路径对带宽资源的利用情况，因此，可以提高带宽资源的利用率。
下面结合说明书附图对本申请实施例作进一步详细描述。
如图3所示，为本申请实施例提供的数据传输系统30示意图。
第一网络侧节点301，配置为向无线侧管理控制器发送第一互联信令；其中，第一互联信令用于指示第一网络侧节点需要与第二网络侧节点建立通信连接。
在具体实施过程中，第一网络侧节点301可以为基站，此时，基站可以根据收到的终端设备发送的相关信息，整合分析出自身与其它基站/EPC实体的互联信息，并且可以根据这些互联信息生成第一互联信令；并将该第一互联信令上报给无线侧管理控制器。此外，因为基站的互联信息会不断地发生变化，所以，基站可以周期性地向无线侧管理控制器发送第一互联信令。
无线侧管理控制器302，配置为基于接收的第一互联信令，向传输侧上层控制器发送第一互连指示信息，发送的第一互联指示信息用于指示建立第一网络侧节点301与第二网络侧节点之间的数据传输路径。
在具体实施过程中，无线侧管理控制器302可以在接收第一互联信令之后，就响应第一网络侧节点301的通信需求，向传输侧上层控制器发送第一互连指示信息，以便指示传输侧上层控制器为第一网络侧节点301与第二网络侧节点之间的通信建立数据传输路径。
此外，无线侧管理控制器302还可以基于第一网络侧节点301在一段时间内发送的第一互联信令，对该第一网络侧节点的通信需求进行预测，并基于预测的第一网络侧节点301与第二网络侧节点之间的通信需求，为其建立数据传输路径。
传输侧上层控制器303，配置为基于接收的第一互连指示信息，确定第一网络侧节点301与第二网络侧节点之间的数据传输路径。
在具体实施过程中，若第二网络侧节点为基站，或位于接入层的临时EPC实体，传输侧上层控制器303基于无线侧管理控制器302发送的第一互连指示信息，确定的第一网络侧节点301与第二网络侧节点之间的数据传输路径可以仅由接入层传输网元组成。此时，第一网络侧节点301与第二网络侧节点之间的数据传输可以在接入层进行迂回(图3中虚线所示路径)，而不用再经过汇聚层和核心层的传输网元，这样，可以有效缓解第一网络侧节点与第二网络侧节点之间进行互联时的延迟，而且可以节省汇聚层和核心层的带宽资源。
传输侧下层控制器304，配置为搜集传输侧下层控制器管辖范围内的多个传输网元的网络拓扑结构，并将该网络拓扑结构上报给传输侧上层控制器303。
在一些实施例中，传输侧下层控制器304还可以利用拓扑发现协议来确定自身管辖范围内传输网元的网络拓扑结构是否发生变化，当确定自身管辖范围内传输网元的网络拓扑结构发生变化时，可以重新搜集该传输侧下层控制器管辖范围内更新后的网络拓扑结构，并将更新后的网络拓扑结 构上报给传输侧上层控制器303。
在具体实施过程中，传输侧下层控制器304还配置为接收传输侧上层控制器303下发的边界路径信息；其中，该边界路径信息中包含多个边界传输网元信息，该边界传输网元为位于传输侧下层控制器边界的传输网元，传输侧下层控制器304基于该边界路径信息，确定该传输侧下层控制器的内部路径信息，并将该内部路径信息发送给传输侧上层控制器303，该内部路径信息中包含连接该传输侧下层控制器的边界传输网元的内部传输网元信息。
相应地，传输侧上层控制器303具体配置为，根据各传输侧下层控制器上报的内部路径信息，以及传输侧上层控制器303下发的边界路径信息，确定第一网络侧节点301与第二网络侧节点之间的数据传输路径(图3中粗线条所示路径)。
传输网元305，配置为基于接收的所述数据传输路径，对第一网络侧节点303与第二网络侧节点之间的数据进行传输。
第二网络侧节点306，配置为基于上述传输网元接收所述第一网络侧节点发送的数据。
此外，在具体实施过程中，无线侧管理控制器在接收第三网络侧节点发送的互连信令时，还可以结合已经确定的第一网络侧节点与第二网络侧节点的互联指示信息，为第三网络侧节点的通信需求生成最合理的互连指示信息。
具体地，当第三网络侧节点需要与第二网络侧节点建立通信连接时，可以向无线侧管理控制器发送第二互连信令。无线侧管理控制器在接收到该第二互连信令后，可以基于该第二互联信令，以及第二网络侧节点与第一网络侧节点之间已建立通信连接的信息，向传输侧上层控制器发送第二互连指示信息，该第二互连指示信息用于指示建立第三网络侧节点与第一 网络侧节点之间的数据传输路径；进一步地，传输侧上层控制器可以基于接收的第二互连指示信息，确定第三网络侧节点与第一网络侧节点之间的数据传输路径。这样，只需要为第三网络侧节点与第一网络侧节点之间建立数据传输路径，第三网络侧节点就可以复用第二网络侧节点与第一网络侧节点之间已经建立的数据传输路径，不但可以充分利用传输侧网络的带宽资源，而且可以减少传输侧上层控制器重复确定传输路径的操作。
在一些实施例中，无线侧管理控制器接收到各网络侧节点发送的多个互连信令时，还可以对各网络侧节点的互联需要进行统计和分析，进而梳理出各网络侧节点之间更优的互联需要信息。
在具体实施过程中，如果无线侧管理控制器接收了多个网络侧节点分别发送的互连信令，还可以基于接收的互连信令、预先设定的互连请求响应规则、这多个网络侧节点已经建立的连接信息，以及与这多个网络侧节点分别请求连接的目标网络侧节点已经建立的连接信息，确定这多个网络侧节点的互联信息。这里，每个网络侧节点的互连信息中包含与该网络侧节点连接的其它网络侧节点信息。其中，预先设定的互连请求响应规则有很多，比如基站同时可以建立的最大连接数、或基站的数据传送量等，在此不再一一列举。此外，预先设定的互连请求响应规则还可以根据多个网络侧节点实际的互联情况进行调整；多个网络侧节点已经建立的连接信息、以及与这多个网络侧节点分别请求连接的目标网络侧节点已经建立的连接信息，均指代这多个网络侧节点当前有效的连接信息，不包括无线侧管理控制器已经指示拆除的网络侧节点的连接信息。
进一步地，无线侧管理控制器再基于确定的上述互连信息，向传输侧上层控制器发送互连指示信息，以便传输侧上层控制器为这多个网络侧节点确定数据传输路径。
下面，以多个网络侧节点都为基站为例，对上述过程进行说明。
假设无线侧管理控制器接收到基站3、基站4、基站5分别发送的互连信令，确定基站3、基站5都需要与基站1建立连接，基站4需要分别与基站1、基站2建立连接，并且，基站1已经与基站2建立有效连接。那么，无线侧管理控制器可以对这些连接需求进行分析，比如，基站4需要分别与基站1、基站2建立连接，而基站1已经与基站2建立有效连接，那么，可以让基站4直接与基站1建立连接，这样，基站1需要同时与基站4和基站2建立连接。假设基站1同时可以建立的最大连接数为3，那么，基站1对于基站3和基站5的连接需求只能满足其中之一，此时，可以对基站3和基站5的数据传送量进行分析，若确定基站3的数据传送量较大，则为基站3与基站1建立连接，拒绝或延迟响应基站5的连接需求；若确定基站5的数据传送量较大，则为基站5与基站1建立连接，拒绝或延迟响应基站3的连接需求。
在具体实施过程中，为了使第一网络侧节点与第二网络侧节点之间的数据传输更加灵活，也为了更好地利用传输侧网络的带宽资源。无线侧管理控制器在确定第一网络侧节点与第二网络侧节点之间的通信结束时，还可以向传输侧上层控制器发送指示拆除数据传输路径的拆除指令；相应地，传输侧上层控制器可以基于接收的拆除指令，拆除第一网络侧节点与第二网络侧节点之间的数据传输路径，这样，第一网络侧节点与第二网络侧节点之间数据传输路径的建立和拆除都更加灵活、快捷，可以在不增加传输网元的前提下，提高传输侧网络的数据传送量。
本申请实施例中，当第一网络侧节点需要与第二网络侧节点进行数据传输时，可以向无线侧管理控制器发送第一互连信令，无线侧管理控制器可以基于接收的第一互联信令，向传输侧上层控制器发送第一互连指示信息，传输侧上层控制器在接收到第一互连指示信息之后，可以确定第一网络侧节点与第二网络侧节点之间的数据传输路径，这样，第一网络侧节点 与第二网络侧节点之间的数据传输路径可以由传输侧上层控制器基于无线侧管理控制器发送的第一互连指示信息来确定，并且该数据传输路径的建立不需要人工干预，更加灵活，此外，传输侧上层控制器在确定该数据传输路径时，还可以考虑已有的数据传输路径对带宽资源的利用情况，因此，可以提高带宽资源的利用率。
下面结合附图对本申请实施例中的数据传输方法做进一步的介绍。
如图4所示，为本申请应用实施例中第一网络侧节点、第二网络侧节点、传输侧上层控制器、传输侧下层控制器，以及传输网元的连接关系示意图，其中，基站1可以代表第一网络侧节点；基站2、临时EPC、EPC均可以代表第二网络侧节点(临时EPC位于接入层，EPC位于核心层)；PTN设备可以代表传输网元。
在具体实施过程中，传输侧网络主要包括接入层、汇聚层和核心层，因此，可以在接入层、汇聚层和核心层分别设置至少一个传输侧下层控制器，以便各传输侧下层控制器分别对自身管辖范围内的传输网元进行管理，所有的传输侧下层控制器由一个传输侧上层控制器进行管理。在一些实施例中，可以预先建立传输侧网络中各传输网元的网络拓扑结构。
具体地，各个传输侧下层控制器先搜集自身管辖范围内的多个传输网元的网络拓扑结构，然后，将各自搜集的网络拓扑结构上报给传输侧上层控制器。此外，因为整个传输侧网络的拓扑结构有可能发生变化，传输侧下层控制器还可以利用拓扑发现协议来确定自身管辖范围内传输网元的网络拓扑结构是否发生变化，当确定自身管辖范围内传输网元的网络拓扑结构发生变化时，可以重新搜集该传输侧下层控制器管辖范围内更新后的网络拓扑结构，并将更新后的网络拓扑结构上报给传输侧上层控制器。
传输侧上层控制器根据各个传输侧下层控制器上报的自身管辖范围内的网络拓扑结构，形成关于传输侧网络的网络拓扑结构，以便为基站与基 站/EPC实体之间的互联确定数据传输路径。
下面分别对本申请应用实施例中基站与基站、以及基站与EPC实体之间进行互联的情况分别进行说明。
1)基站与基站进行互联。
在具体实施过程中，当终端设备与基站1之间的通信连接需要切换到基站2时，基站1可以根据该终端设备的通信切换请求，分析出自身需要与基站2进行互联；基于该互联信息生成第一互联信令，并将该第一互联信令上报给无线控制管理单元。
无线侧管理控制器在接收到第一互联信令之后，可以向传输侧上层控制器发送第一互连指示信息，以便指示传输侧上层控制器为基站1与基站2之间的通信建立数据传输路径。
传输侧上层控制器在接收到第一互连指示信息后，可以确定基站1与基站2之间、由接入层传输网元组成的数据传输路径。这样，基站1与基站2之间的数据传输可以在接入层进行迂回(图4中接入层的环形线条所示路径)，而不用再经过汇聚层和核心层，这样，不但可以有效缓解基站1与基站2之间进行互联时的延迟，而且可以节省汇聚层和核心层的带宽资源。
在具体实施过程中，当基站1与基站2在接入层传输网元建立数据传输路径之后，如果无线侧管理控制器再接收到基站3发送的互连信令，该无线侧管理控制器可以结合已经确定的基站1与基站2的互联指示信息，再考虑接入层各个传输网元的接口利用情况，为基站3生成互联指示信息。
具体地，当基站3需要与基站2建立通信连接时，可以向无线侧管理控制器发送第二互连信令。无线侧管理控制器在接收到该第二互连信令后，可以基于该第二互联信令，以及基站1与基站2之间已建立通信连接的信息，向传输侧上层控制器发送第二互连指示信息，该第二互连指示信息用 于指示建立基站3与基站1之间的数据传输路径，进一步地，传输侧上层控制器可以基于接收的第二互连指示信息，确定基站3与基站1之间的数据传输路径。这样，只需要为基站3与基站1之间建立数据传输路径，基站3就可以复用基站2与基站1之间已经建立的数据传输路径，进而充分利用传输侧网络的带宽资源。
2)基站与EPC进行互联。
在MEC的业务场景中，某些地区临时有数据传输需求，此时就需要采用分布式SGW来进行数据传输以保证较低的业务时延，这样，如果使用传统的传输侧网络架构来临时建立从基站到某个临时EPC实体的数据传输路径，不但效率极低而且不容易对数据传输路径进行拆除，本申请实施例则可以很好地解决这些问题。
在具体实施过程中，当临时EPC实体位于接入层时(图4所示)，基站与该临时EPC实体之间建立数据传输路径的过程，和上述基站与基站之间建立数据传输路径的过程相同，在此不再赘述。
此外，本申请实施例中的临时EPC实体还可以位于汇聚层或核心层。此时，基站与临时EPC/EPC实体建立数据传输路径时，会涉及到多个传输侧下层控制器之间的路径确定，因此和基站与基站在接入层的下层控制器中建立数据传输路径的过程有所不同，下面对基站与EPC实体之间建立数据传输路径的过程进行说明。
具体地，如图5所示，为各个传输侧下层控制器内包含的传输网元示意图，假设基站与标号为1的传输网元相连，EPC实体与标号为14的传输网元相连。当确定基站与EPC实体之间的数据传输路径时，传输侧上层控制器首先确定多组边界传输网元信息，比如确定的边界传输网元信息中包含两组边界网元信息：1、2、5、7、10、12、14和1、3、4、9、10、12、14，并将这些边界传输网元的信息发送给各个传输侧下层控制器；各个传 输侧下层控制器接收到这些边界传输网元信息以后，可以分别在自身管辖的范围内结合各个传输网元的使用情况，确定出内部的传输路径。比如，对于边界网元：1、2、5、7、10、12、14，接入层的下层控制器确定的传输路径为1→2；汇聚层的下层控制器确定的传输路径为5→8→6→7→10，或，5→6→7→10；核心层的下层控制器确定的传输路径为12→14；而对于边界网元：1、3、4、9、10、12、14，接入层的下层控制器确定的传输路径为1→3→4；汇聚层的下层控制器确定的传输路径为9→10；核心层的下层控制器确定的传输路径为12→14。各个传输侧下层控制器在确定内部路径之后，再将这些内部路径信息发送给传输侧上层控制器，那么，传输侧上层控制器可以得到3条路径信息：1→2→5→8→6→7→10→12→14，1→2→5→6→7→10→12→14，以及1→3→4→9→10→12→14；传输侧上层控制器再基于一定的选择标准从这3条路径中选择一条最优的作为基站与EPC实体之间的数据传输路径；其中，选择标准可以为数据传输路径最短，也可为传输网元利用率最大。
在具体实施过程中，基站与临时EPC(非位于接入层)之间建立数据传输路径的过程与上述基站与EPC实体之间建立数据传输路径的过程类似，在此不再赘述。
此外，当基站与基站，或位于接入层的临时EPC实体建立通信连接时，基站与基站/临时EPC实体之间传输的数据仅在接入层进行迂回，此时，可以利用虚拟局域网(Virtual Local Area Network，VLAN)进行数据传输；当基站与位于接入层、或核心层的临时EPC/EPC实体建立通信连接时，会涉及到多个传输侧下层控制器，此时，在接入层仍然可以利用VLAN进行数据传输，而在汇聚层和核心层则可以利用路由表进行数据传输。
在具体实施过程中，为了使基站与基站/EPC实体之间的数据传输更加灵活，也为了更好地利用整个网络的带宽资源。无线侧管理控制器可以周 期性接收各个基站发送的互联信令，如果在预设时长内，比如10分钟，未接收到基站1发送的与基站2进行互联的互联信令，则可以认为该基站1与基站2的通信需求结束，此时，无线侧管理控制器可以向传输侧上层控制器发送拆除指令，该拆除指令用于指示传输侧上层控制器拆除基站1与基站2之间的数据传输路径。
本申请实施例中，当第一网络侧节点需要与第二网络侧节点进行数据传输时，可以向无线侧管理控制器发送第一互连信令，无线侧管理控制器可以基于接收的第一互联信令，向传输侧上层控制器发送第一互连指示信息，传输侧上层控制器在接收到第一互连指示信息之后，可以确定第一网络侧节点与第二网络侧节点之间的数据传输路径，这样，第一网络侧节点与第二网络侧节点之间的数据传输路径可以由传输侧上层控制器基于无线侧管理控制器发送的第一互连指示信息来确定，并且该数据传输路径的建立不需要人工干预，更加灵活，此外，传输侧上层控制器在确定该数据传输路径时，还可以考虑已有的数据传输路径对带宽资源的利用情况，因此，可以提高带宽资源的利用率。
