背景技术
随着通信技术的不断发展，对网络节点也提出了移动的需求，比如在一些大型场馆，旅行团服务等场景中，需要给用户提供一些的应急的业务部署，以及移动的业务体验。
在这些网络节点需要移动的场景中，网络节点需要根据网络的负载，业务的变化，自主移动到合适位置，自动组成一个动态自适应网络，有效地满足用户需求。尤其是接入业务变化或者网络节点移动到其它位置时，对数据转发有新的需求，如：增大数据转发量、改变数据回传路径等。
然而，在现有技术中网络节点通常是固定的或极少移动的，网络节点的回程(backhaul)链路通常是固定的，其数据转发量和数据回传路径也是固定的，无法满足移动场景中移动网络节点对数据转发的需求。可见，现有技术中的回程链路存在无法满足移动场景中移动网络节点的数据转发需求的技术问题。

下面结合附图对本申请实施例技术方案的主要实现原理、具体实施方式及其对应能够达到的有益效果进行详细的阐述。
实施例一
请参考图1，本申请实施例提供一种移动设备，所述移动设备包括：
处理器101，用于获取表征所述移动节点的当前运行状态的当前运行状态信息；
发送器102，用于基于所述当前运行状态信息，向回程节点发送用于调整所述移动节点与所述回程节点间的回程链路的调整请求；
接收器103，用于接收所述回程节点发送的反馈信息，所述反馈信息中包含为所述移动节点分配的回程资源；
所述处理器101还用于基于所述回程资源，调整所述回程链路。
进一步的，在所述基于所述当前运行状态信息，向回程节点发送用于调整回程链路的调整请求之前，所述接收器103还用于：接收服务器发送的移动指令，确定所述移动节点的当前位置、当前移动速度及当前移动方向；
所述处理器101还用于基于所述当前位置、所述当前移动速度及所述当前移动方向，在移动的过程中，获取与所述移动节点之间距离小于等于设定阈值的至少一个备选回程节点；基于所述当前运行状态信息，从所述至少一个备选回程节点中确定所述回程节点。
其中，处理器101获取的所述当前运行状态信息具体包括如下至少一种信息：所述移动节点的当前服务质量信息、当前业务流量信息、当前带宽需求信息及当前电量信息。在当前运行状态信息为所述当前电量信息时，所述处理器101还用于获得与所述当前电量信息对应的当前剩余工作时长，及与所述当前剩余工作时长对应的当前带宽期望值；在所述调整请求中携带所述当前带宽期望值；并由所述发送器102向所述回程节点发送携带所述当前带宽期望值的所述调整请求，使得所述回程节点能够基于所述当前带宽期望值调整所述回程资源中的回程带宽。
本申请实施例提供的移动设备即移动节点，当所述回程节点与所述移动设备间未建立有所述回程链路时，移动设备的所述处理器101可以基于所述回程资源调整所述回程链路，如：与回程节点建立新的回程链路；或者，当所述回程节点与所述移动设备间建立有所述回程链路时，移动设备的所述处 理器101也可以基于所述回程资源调整所述回程链路，如：调整与回程节点之间已建立的回程链路的带宽。
请参考图2，对应上述移动设备即移动节点，本申请实施例还提供一种应用于该移动节点的回程链路调整方法，该方法包括：
S201：所述移动节点获取用于表征所述移动节点的当前运行状态的当前运行状态信息；
S202：所述移动节点基于所述当前运行状态信息，向回程节点发送用于调整所述移动节点与所述回程节点间的回程链路的调整请求；
S203：所述移动节点接收所述回程节点发送的反馈信息，所述反馈信息中包含为所述移动节点分配的回程资源；
S204：所述移动节点基于所述回程资源，调整所述回程链路。
在具体实施过程中，移动节点可以为无线通信领域中的可移动接入节点(Access Point，AP)，也可以为无线通信领域中的中继节点(Relay Node，RN)。移动节点的当前运行状态包括移动节点的服务质量(Quality of Service，QoS)、业务流量、数据回传时的带宽需求、自身的电量等，相应的表征移动节点当前运行状态的当前运动状态信息可以包含如下至少一种信息：所述移动节点的当前服务质量信息、当前业务流量信息、当前带宽需求信息及当前电量信息。移动节点可能因为位置的移动、接入业务变化等原因，其当前运行状态会相应的发生变化，对应不同的当前运行状态移动节点需要不同的回程链路来向网络回传数据，为此移动节点执行S201获得其自身的当前运行状态信息。
移动节点在获得自身的当前运行状态信息后，执行S202基于当前运行状态信息向回程节点发送调整请求。具体的，移动节点可以根据当前运动状态信息，计算获得自身通过回程链路向回程节点回传数据时需要的回程资源，例如：回程链路的带宽大小，然后在向回程节点发送的调整请求中携带用于调整回程链路的回程资源信息。当然，移动节点也可以将当前运行状态信息携带在调整请求中发送给回程节点，使得回程节点根据移动节点的当前运行 状态信息计算获得移动节点所需要的回程资源，本申请实施例并不限制回程资源由移动节点计算获得。
相应的，回程节点在接收到移动节点的调整请求后，响应移动节点的调整请求，为移动节点分配回程资源，并将其分配的回程资源携带在反馈信息中发送给移动节点。接着，移动节点执行S203接收回程节点发送的反馈信息，并进一步执行S204基于回程节点分配的回程资源调整回程链路。可选的实现方式包括以下两种：
一、当回程节点与移动节点间未建立有回程链路时，移动节点基于回程资源，调整回程链路时，具体可以基于回程资源在移动节点与回程节点之间建立新链路作为回程链路。
二、当回程节点与移动节点间建立有回程链路时，移动节点基于回程资源调整回程链路时，具体可以基于所述回程资源调整已建立的回程链路的带宽。
在本申请实施例中，移动节点在基于当前运行状态信息向回程节点发送用于调整回程链路的调整请求之前，还接收服务器发送的移动指令，确定移动节点的当前位置、当前移动速度及当前移动方向；然后基于所述当前位置、所述当前移动速度及所述当前移动方向，在移动节点移动的过程中，获取与所述移动节点之间距离小于等于设定阈值的至少一个备选回程节点；进而基于所述当前运行状态信息，从所述至少一个备选回程节点中确定出所述回程节点。其中，设定阈值可以为移动节点信号覆盖范围的最大值，使得获取到的至少一个备选回程节点均在移动节点的覆盖范围内。移动节点在移动过程中，根据确定的移动节点的当前位置、当前移动速度及当前移动方向来选择回程节点，为此选择的回程节点均在移动节点的移动路线上，使得移动接点在移动过程中调整请求能够被及时反馈，以快速建立新的回程链路。
具体的，移动节点可以基于自身的当前位置、当前移动速度及当前移动方向预测出下一时刻自身所在的位置，以确定与下一时刻所在位置距离小于等于设定阈值的至少一个备选回程节点。进一步的，移动节点从所述至少一 个备选回程节点确定回程节点时，可以确定出一个回程节点，也可以确定出多个回程节点。移动节点确定出多个回程节点时，向多个回程节点发送调整请求，使得移动节点能够根据所述多个回程节点反馈的回程资源，选择与最优的回程节点建立新链路即新的回程链路。
例如：移动节点向回程节点A和回程节点B均发送了调整请求，回程节点A为移动节点分配的回程资源中回程链路带宽为0.1M，回程节点B为移动节点分配的回程资源中回程链路带宽为0.2M，那么移动节点在其他回程资源相同的情况下选择与带宽大的回程节点B建立新链路，以更好的向网络回传数据。
下面结合不同的运行场景，对本申请实施例提供的回程链路调整方法进行举例说明。
一、在移动过程中，建立新的回程链路
请参考图3，终端STA和移动节点A都通过移动节点B接入到网络中，而移动节点B则通过回程节点backhaul A回传到网络中。而移动节点B接收服务器的移动命令，要求移动节点B移动到新的位置。移动节点B在移动的过程中，由于位置的变化回程节点backhaul A已不再适合移动节点B回传数据，因此需要选择更好的回程节点建立新的回程链路。建立新的回程链路的具体实施过程如下：
S301：移动节点B接入到回程节点backhaul A。
S302：移动节点B接收服务器的移动命令后，该移动命令要求移动节点B移动到新的位置Location 1。
S303：移动节点B确定自身的当前位置，并根据Location 1和当前位置确定移动速度及移动方向，进一步根据当前位置、移动速度及移动方向确定至少一个备选回程节点，从至少一个备选回程节点中选择回程节点。
例如：移动节点根据当前位置、移动速度及移动方向预测出下一时刻的位置为Location 2，移动节点进一步结合地图信息，获知下一个时刻它可以接入到的至少一个备选回程节点，并从该至少一个备选回程节点中确定出发送 调整请求的回程节点为backhaul B。
S304：移动节点B获得自身的当前运行状态信息，例如当前业务流量信息，在调整请求中携带当前业务流量信息，向回程节点backhaul B发送调整请求，以使回程节点backhaul B在接收到调整请求后，根据调整请求中的业务流量信息为移动节点B分配回程资源。
S305：移动节点B接收回程节点backhaul B发送的反馈信息，从该反馈信息中获得backhaul B分配的回程资源。
S306：移动节点B根据backhaul B分配的回程资源，与新的回程节点backhaul B建立新的回程链路，进行回传数据的传输。
S307：移动节点B同旧的回程节点backhaul A断开链路。
二、根据接入业务的变化，调整已建立的回程链路
请参考图4，终端STA和移动节点A都通过移动节点B接入到网络中，而移动节点B则通过回程节点backhaul A回传数据到网络中。移动节点B可以根据接入业务的变化，调整已建立的回程链路，具体过程如下：
S401：移动节点B将终端STA和/或移动节点A的数据流通过回程节点A传输到网络中。
S402：移动节点B根据终端STA和/或移动节点A的业务Qos信息，为不同的Qos业务建立不同的回程链路。
S403：自移动节点B检测到自身的当前运行状态信息：数据Qos或者带宽需求发生变化(如：终端STA和/或移动节点A的语音业务、视频业务增多，使得自身的数据Qos或者带宽需求发生变化)，计算出新的回程资源需求(比如：满足当前接入业务的回程链路的带宽阈值)。
S404：移动节点B向回程节点backhaul A发起调整请求，该调整请求用于向回程节点backhaul A请求分配回程资源(如：增加语音业务的承载带宽，增加视频业务的承载带宽)。进而使回程节点backhaul A根据移动节点B的调整请求为移动节点B分配新的回程资源，并通过反馈信息发送给移动节点B。
S405：移动节点B接收回程节点backhaul A发送的反馈信息，获得反馈信息中包含的回程资源，并根据回程资源调整与回程节点backhaul A已建立的回程链路，进而进行新的回程传输。
例如：回程节点backhaul A为移动节点B分配的是回程资源为0.5M带宽的回程链路，而移动节点B与回程节点backhaul A已建立的回程链路的带宽为0.1M和0.2M，那么移动节点B则可以将回程链路的带宽调整为0.2和0.4M(如：分别增加语音业务的承载带宽为0.2M，增加视频业务的承载带宽为0.4M)。
三、根据接入业务的变化，建立新的回程链路
请参考图5，终端STA和移动节点A都通过移动节点B接入到网络中，而移动节点B则通过回程节点backhaul A回传数据到网络中。移动节点B可以根据接入业务的变化，建立新的回程链路，具体过程如下：
S501：移动节点B将终端STA和/或移动节点A的数据通过回程节点A传输到网络中。
S502：移动节点B根据终端STA和/或移动节点A的业务Qos信息，为不同的Qos业务建立不同的backhaul承载。
S503：自移动节点B检测到自身的当前运行状态信息：数据Qos或者带宽需求发生变化(如：终端STA和/或移动节点A的语音业务、视频业务增多，使得自身的数据Qos或者带宽需求发生变化)，计算出新的回程资源需求(比如：满足当前接入业务的回程链路的带宽阈值)，但当前回程节点A已经无法再分配新的回程资源。
S504：移动节点B向回程节点backhaul B发起调整请求，该调整请求用于向回程节点backhaul B请求分配回程资源，以回传增加的语音业务、视频业务的承载带宽。进而使回程节点backhaul B根据移动节点B的调整请求为移动节点B分配新的回程资源，并通过反馈信息发送给移动节点B。
S505：移动节点B接收回程节点backhaul B发送的反馈信息，获得反馈信息中包含的回程资源，并根据回程资源与回程节点backhaul B建立新的回 程链路，进而进行新的回程传输。
例如：回程节点backhaul B为移动节点B新分配了回程资源：0.3M带宽的新回程链路，于是移动节点B与回程节点backhaul B建立0.3M带宽的新回程链路，以向网络回传增加的语音业务和视频业务。
四、新节点接入，调整已建立的回程链路
请参考图6，终端STA1和移动节点A1都通过移动节点B接入到网络中，而移动节点B则通过回程节点backhaul A回传到网络中。若新的终端STA2和/或移动节点A2接入移动节点B，此时移动节点B可能需要调整已建立的回程链路，具体执行过程如下：
S601：移动节点B与backhaul A建立回程链路，将终端STA1和移动节点A1传入的数据，通过回程节点backhaul A回传到网络中。
S602：移动节点B检测到新的终端STA2和/或移动节点A2接入。
S603：移动节点B获得自身的当前带宽需求信息和/或当前流量信息，当前带宽需求信息和/或当前流量信息表明移动节点B自身已建立的回程链路的带宽已经不能满足需求，计算获得新的带宽需求。
S604：自移动节点B向回程节点backhaul A发起调整请求，该调整请求中携带新的带宽需求，用于请求新的回程资源，使得backhaul A在接收到调整请求后，为移动节点B分配新的回程资源并向移动节点B发送携带回程资源的反馈信息。
S605：移动节点B接收回程节点backhaul A的反馈信息，从反馈信息中获得backhaul A分配的回程资源。
S606：移动节点B根据回程资源调整与backhaul A建立的回程链路，根据回程资源扩展回程链路的带宽，进而进行新的回程传输。
五、根据电流信息，调整已建立的回程链路
请参考图7，终端STA和移动节点A都通过移动节点B接入到网络中，而移动节点B则通过回程节点backhaul A回传到网络中。由于移动节点B储备的电量有限，在工作过程中会出现电量不足的情况。移动节点在电量不足 的情况下，未来完成待回传数据的回传执行如下步骤：
S701：移动节点B接入到回程节点backhaul A，通过回程节点backhaul A向网络回传终端STA和/或移动节点A的数据。
S702：移动节点B获取自身的当前电量信息，获得与当前电量信息对应的当前剩余工作时长，及与所述当前剩余工作时长对应的当前带宽期望值。较佳的，移动节点B可以在当前电量信息表明移动节点B的电量不足时，计算自身的剩余可工作时间，及对应的回程带宽期望值。
S703：移动节点B在调整请求中携带当前带宽期望值，向回程节点backhaul A发送调整请求，使得回程节点backhaul A能够基于当前带宽期望值调整回程资源中的回程带宽，并相应的向移动节点B发送反馈携带回程资源的反馈信息。
S704：移动节点B接收回程节点backhaul A发送的反馈信息，从该反馈信息中获得回程节点backhaul A分配的回程资源。
S705：移动节点B基于回程资源中的回程资源调整与回程节点backhaul A之间的回程链路(如：将已建立的回程链路的带宽调整为当前带宽期望值)，然后，进行新的回程传输。
实施例二
