Description

一种数据多流传输方法、装置、锚点及系统
本申请要求于2014年12月18日提交中国专利局、申请号为201410803792.6、发明名称为“一种数据多流传输方法、装置、锚点及系统”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
本发明涉及通信技术领域，更具体地说，涉及一种数据多流传输方法、装置、锚点及系统。
背景技术
随着移动用户的增加，以及对高速业务体验的诉求，未来无线网络将通过网络分层和MSA(Multi Streaming Aggregation，多流汇聚)技术的完美结合，从而使得移动用户无论处于网络的哪个位置，都能够享受到高速且稳定的数据连接服务，实现超宽带、零等待和无处不在的移动宽带服务，带来高速、高质量的业务体验。
网络分层是指多层的网络架构，包括Host Layer(主层)和Boosting Layer(加速层)，图1示出了网络分层架构的示意图，可进行参照，其中，Host Layer主要用于确保网络覆盖，主要由Macro Cell(宏站)组成，Host Layer通过建立的Host link(上位机链接系统)来为用户提供信令和基本数据的传输，提供无处不在的连接，保证可靠的基本业务，如图1中用户UE(用户设备，User Equipment)1～UE4中的Host Link。Boosting Layer则主要用于提升网络容量，可以由多种形态的网络构成，如图1中Small Cell(微站，可以是Micro Cell、Pico Cell或Femto Cell等)、WiFi AP(无线保真节点)(可以是基于IEEE 802.11b标准的无线局域网，Access Point，接入节点)等；Boosting Layer通过建立的Boosting link(加速链接系统)来为用户提供高速率的数据传输，为用户提供最佳的用户业务体验。
MSA是有机聚合Host Layer和Boosting Layer的关键技术，它通过一个集中的节点BBU Pool(Base Band Unit Pool，基带单元池)或SRC(Single Radio Controller，单一无线控制器)和多个分发节点为用户提供多流汇聚，即网络侧的数据可通过多条传输路径发送至UE，从而进一步提升了用户感受和网络容量。
图2示出了现有技术进行数据多流传输的示意图，可进行参照，UE通过基站接入蜂窝网络，基站通过与Internet(因特网)之间的无线回传设备，使得UE与Internet之间存在数据通信链路，进而使得UE接入到Internet；UE通过WiFi AP接入到WLAN(Wireless Local Area Network，无线局域网)网络，WiFi AP通过与Internet之间的无线回传设备，使得UE与Internet之间存在数据通信链路，进而使得UE接入到Internet，基站和WiFi AP可以称为是UE接入网络的接入节点。
在数据多流传输的场景下，UE可通过蜂窝网络所拥有的多个基站与Internet之间的传输路径，和/或，WLAN网络所拥有的多个WiFi AP与Internet之间的传输路径，实现数据的多流传输。在图2所示网络架构的基础上，现有技术在进行数据多流传输时，图2所示MSA业务分流/汇聚控制点将用于控制多流传输业务的分流和汇聚，且在基站接入链路资源可用，以及WiFi AP接入链路的资源可用时，就启用多条数据传输路径，实现数据至UE的多流传输。
本发明的发明人研究发现：图2所示网络架构中，蜂窝网络和WLAN网络是两张独立的网络，资源是独立的，特别地，靠近接基站或WiFi AP侧的第一段传输资源(图2中所示基站的无线回传设备，或WiFi AP的无线回传设备与Internet的无线回传设备之间的无线回传链路的资源)也是独立的，无法共享；现有技术仅在基站接入链路资源可用，以及WiFiAP接入链路的资源可用时，就启用数据的多流传输，而没有考虑基站或WiFi AP侧无线回传链路的资源是否可用，若无线回传链路的资源不足，则采用多流传输所导致的数据的传输速率将变低，导致无法提供多流传输带来的高速用户业务体验。
发明内容

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行描述。
图3为本发明实施例提供的实现数据多流传输方法的系统的网络架构图，该网络架构表示的是宏微一体化网络，参照图3，该网络架构可以包括：至少一个接入节点20，锚点30和无线回传设备40；锚点30可以为宏站等具有支持连接Backhaul，支持UE的接入，支持对其它节点及链路的资源数据获取、分配和管理的功能的设备。
可选的，接入节点20可以为Small Cell(如基站等)，也可以为WiFi AP等；各个接入节点20均设置有无线回传设备40，各个接入节点20通过设置的无线回传设备40可与锚点30设置的无线回传设备40构建无线回传链路；可选的，各接入节点与锚点之间可通过无线回传设备建立的无线回传链路进行数据传输；
可选的，UE与锚点之间可通过锚点空口接入链路直接进行数据传输，从而绕过接入节点；
可见，在本发明实施例中，UE与锚点之间的数据传输路径包括：
1、UE-接入节点-无线回传链路-锚点；
2、UE-锚点空口接入链路-锚点。
其中，UE-接入节点-无线回传链路-锚点的数据传输路径包括：UE-基站-无线回传链路-锚点的数据传输路径，这类数据传输路径可能有多条，如基站数量为多个的情况时，对应的无线回传链路的数量有可能是多个；及UE-WiFi AP-无线回传链路-锚点的数据传输路径，这类数据传输路径也可能有多条，如WiFi AP为多个的情况时，对应的无线回传链路的数量有可能是多个。
其中，本发明实施例中无线回传链路中采用的无线回传方式可以是点到多点(P2MP，Point-to-Multi-Point)的无线传输技术，如Sub-6GHz频段Unlicensed传输、Sub-6GHz频段Licensed传输或锚点的自回传技术(Self-backhaul)；也可以是点到点(P2P，Point-to-Point)的无线传输技术，如Sub-6GHz频段、常规微波频段、或者60GHz以上高频微波传输；也可以是上述提到的各种无线传输技术的组合。当然也可以是其他的无线传输技术，如P2P光纤、P2MP光纤等都可以使用，上述所举仅为示例。
可以知道，从锚点到UE方向，多流数据传输的分发点在锚点，汇聚点在UE；从UE到锚点方向，多流数据传输的分发点在UE，汇聚点在锚点。动态多流数据传输的业务集中控制点在锚点，由锚点来统一决策和控制多流数据的传输。
基于上文描述，图4示出了本发明实施例提供的数据多流传输方法，该方法可基于图3所示的宏微一体化网络，参照图4，该方法可以包括：
步骤S100、锚点获取所述UE至所述锚点之间的各条数据传输路径的资源可用性数据，所述资源可用性数据包括各接入节点与所述锚点之间的无线回传链路资源数据；
可以知道，UE与锚点之间的数据传输路径可以包括：UE-接入节点-无线回传链路-锚点的数据传输路径，及UE-锚点空口接入链路-锚点的数据传输路径；其中UE-接入节点-无线回传链路-锚点的数据传输路径又可包括：由至少一个基站构成的UE-基站-无线回传链路-锚点的至少一条数据传输路径，和/或，由至少一个WiFi AP构成的UE-WiFi AP-无线回传链路-锚点的至少一条数据传输路径。
可选的，锚点所获取的UE至所述锚点之间的各条数据传输路径的资源可用性数据可以包括：各个接入节点与UE之间的空口接入链路资源数据，各接入节点与所述锚点之间的无线回传链路的资源数据，和UE与锚点之间的锚点空口接入链路的资源数据。
可选的，锚点也可获取到锚点与核心网之间的传输链路资源数据，得到可用带宽等资源信息，如锚点可实时检测锚点与核心网之间的传输链路资源情况，经处理后，得到可用带宽等资源信息。
可见，本发明实施例在进行数据多流传输时，将检测各接入节点与所述锚点之间的无线回传链路的资源数据，由检测的各接入节点与所述锚点之间的无线回传链路的资源数据指导后续的数据多流传输流程，从而避免现有技术没有考虑基站或WiFi AP侧无线回传链路的资源是否可用的情况发生。
步骤S110、所述锚点根据所述各条数据传输路径的资源可用性数据，确定多条目标数据传输路径，通过所述多条目标数据传输路径将业务数据多流传输至所述UE，所述多条目标数据传输路径包括目标接入节点与所述锚点之间通过无线回传设备建立的对应的无线回传链路，所述目标接入节点为所述至少一个接入节点中传输业务数据的接入节点；
可选的，锚点在获取了各条数据传输路径的资源可用性数据后，可决定当前是否启用数据多流传输；终端UE与锚点之间是否采用多路径传输(即多流传输)，取决于多个因素，包括UE请求的业务是否需要采用多路径传输、UE是否支持多路径传输、UE与锚点之间是否存在多条传输路径、UE与锚点之间多条传输路径上的资源可用性是否与多路径传输相匹配(如UE与锚点之间多条传输路径上的资源是否能够支持多路径传输)、锚点与核心网之间的资源可用性与多路径传输相匹配(如锚点与核心网之间的资源是否能够支持多路径传输)等。
可选的，若用一个公式表示是否启用数据多流传输，则可以表示为
终端UE与锚点多路径传输(是否启用，多流传输方案)＝f(UE请求业务，UE支持情况，UE与锚点之间多条传输路径的资源可用性，锚点与核心网之间资源可用性)
当出现下述条件时，终端UE不启用多路径传输：
1、终端UE不支持多路径传输；
2、UE～锚点之间只有一条满足UE业务质量的传输路径；
3、锚点～核心网之间的资源不足，不能支持UE～锚点之间的多路径传输。
当出现下述条件时，终端UE可以启用多路径传输：
1、终端UE支持多路径传输；
2、UE～锚点之间存在多条满足UE业务质量的传输路径；
3、UE～锚点之间的任一条传输路径资源不能传输UE请求的所有业务，需要通过多条传输路径来传输；
4、锚点～核心网之间的资源充足，可以满足UE～锚点之间的多路径传输。
锚点在启用数据多流传输时，可选取哪些数据传输路径进行数据的多流传输；在本发明实施例中锚点可根据UE业务请求及资源可用性情况，支持以下多流汇聚传输方案：
1、UE-接入节点-无线回传链路-锚点，其中无线回传链路可以具有多条；
2、UE-接入节点-无线回传链路-锚点+UE-锚点空口接入链路-锚点，其中无线回传链路也可以具有多条。
可以看出，无论采用何种多流汇聚传输方案，由于UE-锚点空口接入链路-锚点的数量一般只有一条，因此UE-接入节点-无线回传链路-锚点的数据传输路径在多流数据传输过程中为必要的数据传输路径。
需要说明的是，多条目标数据传输路径是指本发明实施例进行多流数据传输的路径，由于UE-接入节点-无线回传链路-锚点的数据传输路径为多流数据传输过程中的必要数据传输路径，因此多条目标数据传输路径必然包括了目标接入节点与所述锚点之间通过无线回传设备建立的对应的无线回传链路；目标接入节点与所述锚点之间的无线回传链路，及目标接入节点与UE之间的数据链路构成了完成的数据传输路径。目标接入节点为至少一个接入节点中传输业务数据的接入节点，即本发明实施例所选用的进行多流数据传输的接入节点；目标接入节点可以为选取的目标基站和/或目标WiFi AP。
步骤S120、目标接入节点通过对应的无线回传链路将业务数据发送至所述UE。
可选的，若本发明实施例不采用UE-锚点空口接入链路-锚点的数据传输路径进行多流数据传输，则所采用的UE-接入节点-无线回传链路-锚点存在多条，本发明实施例可仅使用目标接入节点通过对应的无线回传链路将 业务数据发送至所述UE；
可选的，若本发明实施例采用UE-锚点空口接入链路-锚点的数据传输路径进行多流数据传输，则业务数据将分配至UE-接入节点-无线回传链路-锚点的数据传输路径，和UE-锚点空口接入链路-锚点的数据传输路径上进行传输；本发明实施例除目标接入节点通过对应的无线回传链路将部分业务数据发送至所述UE外，锚点也将通过锚点空口接入链路将部分业务数据直接传输至UE。
可选的，UE可通过多条的UE-接入节点-无线回传链路-锚点的数据传输路径获取业务数据；也可通过至少一条UE-接入节点-无线回传链路-锚点的数据传输路径，和UE-锚点空口接入链路-锚点的数据传输路径共同获取业务数据。
本发明实施例提供的数据多流传输方法，基于宏微一体化网络，各接入节点与所述锚点之间通过无线回传设备建立的无线回传链路进行数据传输；在进行数据多流传输时，锚点可获取所述UE至所述锚点之间的各条数据传输路径的资源可用性数据，所述资源可用性数据包括各接入节点与所述锚点之间的无线回传链路的资源数据，锚点可根据所述各条数据传输路径的资源可用性数据，确定多条目标数据传输路径，通过所述多条目标数据传输路径将业务数据多流传输至所述UE，所述多条目标数据传输路径包括目标接入节点与所述锚点之间通过无线回传设备建立的对应的无线回传链路，所述目标接入节点为所述至少一个接入节点中传输业务数据的接入节点；进而目标接入节点通过对应的无线回传链路将业务数据发送至所述UE，使得UE通过所述多条目标数据传输路径获取所述业务数据。本发明实施例提供的数据多流传输方法，考虑了各接入节点与所述锚点之间的无线回传链路的资源数据作为选取目标数据传输路径的依据，避免了现有技术没有考虑基站或WiFi AP侧无线回传链路的资源是否可用的情况发生，使得数据多流传输的速率得以保证。本发明实施例在宏微一体化组网架构下，结合回传资源，实现了动态的多流传输，提供了高速、高质量的数据多流传输的用户业务体验；同时实现无线接入资源和回传资源的最大化利用，避免出现回传资源紧缺导致的拥塞丢包，同时避免接入侧无线资源的浪费。
可选的，前文描述的是从锚点到UE方向的多流数据传输，多流数据传输的分发点在锚点，汇聚点在UE；本发明实施例还可支持从UE到锚点方向的多流数据传输，多流数据传输的分发点在UE，汇聚点在锚点。对应的，UE可通过所述多条目标数据传输路径将业务数据传输至锚点，所述多条目标数据传输路径包括目标接入节点与所述锚点之间通过无线回传设备建立的对应的无线回传链路；对应的，锚点可通过所述多条目标数据传输路径接收UE发送的业务数据，所述多条目标数据传输路径包括目标接入节点与所述锚点之间通过无线回传设备建立的对应的无线回传链路。
可选的，在本发明实施例中，锚点收到核心网的数据后，可在IP层进行数据的分流，将IP数据包分发到不同的传输路径上，具体的传输路径根据前述方法确定，UE收到来自多条传输路径的数据流后，进行汇聚，再传递到应用层。同理，UE应用层产生的数据流，在IP层进行多路径的分流，将IP数据包分发到不同传输路径上传输，数据流经过多条传输路径传输到锚点后，在IP层进行汇聚，再送到核心网。
锚点侧IP数据流的分流和汇聚过程中，锚点支持用户IP数据流的识别，将用户IP数据包分发到不同传输路径上传输。终端UE侧，用户IP数据流的分流，可以通过安装一个应用程序来实现，也可以通过修改操作系统，实现用户IP数据包的分流和汇聚。
可选的，IP层数据包的分流和汇聚传输，可根据可用的多条传输路径上的资源可用性，包括带宽、时延、丢包率、抖动等信息，来确定IP数据包的传输路径，具体如下：
本发明实施例可在各目标数据传输路径的资源均大于设定值时，优先将数据包分流到资源消耗较少的传输路径上；各目标数据传输路径的资源均大于设定值时，表示各目标数据传输路径均可保证用户业务体验；本发明实施例可在各目标数据传输路径均可保证用户业务体验的情况下，优先将数据包分流到资源消耗较少的传输路径上。例如，图5示出了数据多流传输示意图，参照图5，若多路传输选取了传输路径1和传输路径2为UE业务提供数据传输，则在传输路径1和传输路径2都可以提供相同的用户业务体验时，优先将用户业务数据分流到传输路径2上传输；
本发明实施例可在目标数据传输路径的资源小于设定值时，将重要的高优先级数据包分流到资源相对充足的传输路径上，将低优先级的数据包分流到资源相对紧张的传输路径上；目标数据传输路径的资源小于设定值时表示传输路径的资源紧张，在传输路径的资源紧张的情况下，本发明实施例可优先将重要的高优先级数据包分流到有质量保证的传输路径上，将低优先级的数据包分流到无法提供质量保障的传输路径上。例如，图5中，假设基站的无线回传采用专用Licensed频谱，且频谱较少，能够提供的带宽较小，能够提供质量保证，而WiFi AP的无线回传采用的是Unlicensed频谱，频谱较多，能够提供的峰值带宽较大，但不能提供质量保证。若多路传输选取了传输路径2和传输路径3为UE业务提供数据传输，当UE业务流量较大时，需要将高优先级数据分流到传输路径2上传输，而将低优先级数据分流到传输路径3上传输；
当某一条传输路径的可用资源可以满足UE业务请求时，只需选取一条传输路径传输UE的业务数据流；
若锚点与核心网之间的传输资源不足支持UE～锚点之间的多条数据流传输的流量，则不选择多流传输方案，只选择其中一条传输路径传输UE数据。
可选的，在确定目标数据传输路径时，锚点可根据UE所处于的信号覆盖区域，各个接入节点与UE之间的空口接入链路资源数据，各接入节点与所述锚点之间的无线回传链路的资源数据，和UE与锚点之间的锚点空口接入链路的资源数据，确定处于所述信号覆盖区域，链路资源(信号覆盖区域内的空口接入链路资源数据，或者无线回传链路的资源)满足预定条件的数据传输路径为目标数据传输路径；下面以接入节点包括基站和WiFi AP进行说明，基站的数量可以为至少一个，WIFI AP的数量也可以为至少一个，则本发明实施例提供的进行多流数据传输的多条目标数据传输路径可以包括下述情况：
情况1：“UE-基站-无线回传链路-锚点”+“UE-WiFi AP-无线回传链路-锚点”的多流传输；
图6示出了目标数据传输路径架构的一种可选示意图，可进行参照；依 照选取目标数据传输路径的条件(确定处于所述信号覆盖区域，链路资源满足预定条件的数据传输路径为目标数据传输路径)，本发明实施例可在UE在基站和WiFi AP覆盖区域，空口接入链路资源充足，基站与锚点之间的无线回传链路资源充足，WiFi AP与锚点之间的无线回传链路资源充足，同时，UE有高速率的业务请求时；则可通过情况1所示的数据传输路径进行多流传输；图6所示为基站和WiFi AP为分离设备情况下的目标数据传输路径的架构示意图，基站与WiFi AP为分离的独立设备，分别通过各自对应的无线回传链路与锚点建立连接。无线回传链路可以是点到多点传输技术，由基站和WiFi AP共享，无线回传链路也可以是点到点传输技术，分别传输基站和WiFi AP业务流。图6为小站和WiFi AP共享点到多点的无线回传链路。
图7示出了目标数据传输路径架构的另一种可选示意图，可进行参照；图7所示为基站和WiFi AP为合一设备情况下的目标数据传输路径的架构示意图，如图7所示，基站设备内置WiFi AP功能，即基站与WiFi AP合一，通过共享的无线回传链路与锚点建立连接。
在本发明实施例中，锚点为多流传输的决策控制点，根据UE接入链路的资源可用性、无线回传链路资源可用性，结合UE业务请求所需的资源，以及锚点与核心网之间的传输资源可用性，可动态控制是否采用“UE-基站-无线回传链路-锚点”+“UE-WiFi AP-无线回传链路-锚点”的多条路径传输UE业务数据，为UE提供高速业务流数据传输。若“UE-基站-无线回传链路-锚点”或“UE-WiFi AP-无线回传链路-锚点”各自的传输路径资源可以满足UE请求的业务需求，锚点控制决策可选取仅由“UE-基站-无线回传链路-锚点”提供UE业务传输，或仅由“UE-WiFi AP-无线回传链路-锚点”提供UE业务传输。
可选的，基站与锚点之间的无线回传、WiFi AP与锚点之间的无线回传可以是一条物理链路，也可以是多条物理链路。两条物理链路的情况下可以包括Unlicensed无线回传链路和Licensed无线回传链路；采用Unlicensed无线回传链路和Licensed无线回传链路可使得无线回传链路的资源更丰富，既有提供可靠保证的Licensed传输资源，又有不保证质量的Unlicensed 传输资源。因此，锚点在进行数据传输流路径选择决策及业务调度时，可以进行更精细管理。典型应用之一就是带宽需求较小、重要的高优先级数据优先在Licensed回传链路上传输，而把流量较大、中低优先级数据分发到Unlicensed回传链路上传输。
情况2：多条“UE-基站-无线回传链路-锚点”数据传输路径的多流传输，如基站包括基站1和基站2时，可采用“UE-基站1-无线回传链路-锚点”+“UE-基站2-无线回传链路-锚点”进行多流传输；
UE在基站1和基站2的覆盖区域，UE与基站1的空口接入链路资源充足，UE与基站2的空口接入链路资源充足，基站1、基站2与锚点之间的无线回传链路资源充足，同时UE有高速率的业务请求时，本发明实施例可采用“UE-基站1-无线回传链路-锚点”+“UE-基站2-无线回传链路-锚点”的数据传输路径进行多流传输。
图8示出了目标数据传输路径架构的再一种可选示意图，可进行参照，图8中，基站1和基站2共享相同的点到多点无线回传链路，与锚点建立传输连接；图9示出了目标数据传输路径架构的又一种可选示意图，可进行参照，图9中，基站1和基站2采用独立的点到点无线回传链路，分别与锚点建立传输连接。同理，基站1、基站2与锚点之间的无线回传链路也可以是多通道链路，如Unlicensed无线回传链路加上Licensed无线回传链路两条通道，或者两条Licensed无线回传通道等。
在本发明实施例中，锚点为UE多流传输的决策控制点，动态控制是否采用“UE-基站1-无线回传链路-锚点”与“UE-基站2-无线回传链路-锚点”等多条路径传输UE的业务流数据，以提供高速用户业务体验。若“UE-基站1-无线回传链路-锚点”或“UE-基站2-无线回传链路-锚点”各自传输路径的资源可以提供UE请求业务需求，锚点可选择仅由“UE-基站1-无线回传链路-锚点”传输路径传输UE业务，或仅由“UE-基站2-无线回传链路-锚点”传输路径传输UE业务。
显然，本发明实施例虽以基站数量为2进行多条“UE-基站-无线回传链路-锚点”数据传输路径进行多流数据传输的说明，但基站数量的取值可视实际情况而定，选取基站数量为2(基站1和基站2)的描述，仅为一种可选 方式，仅为使得本发明实施例描述的采用多条“UE-基站-无线回传链路-锚点”数据传输路径进行数据多流传输的说明更易便于理解。
情况3：“UE-基站-无线回传链路-锚点”+“UE-WiFi AP-无线回传链路-锚点”+“UE-锚点空口接入链路-锚点”进行多流传输，其中“UE-基站-无线回传链路-锚点”的数据传输路径为至少一条，“UE-WiFi AP-无线回传链路-锚点”的数据传输路径为至少一条；
UE在锚点、小站、WiFi-AP的覆盖区域，“UE-基站-无线回传链路-锚点”，“UE-WiFi AP-无线回传链路-锚点”和“UE-锚点空口接入链路-锚点”中任何一条传输路径的资源都无法满足UE请求业务的传输，这时，锚点可根据各条传输路径上资源信息，动态控制是否采用多路径传输，以及采用哪些传输路径为UE提供业务传输；在各条传输路径的资源均都较少时，本发明实施例结合“UE-基站-无线回传链路-锚点”，“UE-WiFi AP-无线回传链路-锚点”和“UE-锚点空口接入链路-锚点”进行多流数据传输。
图10示出了目标数据传输路径架构的又另一种可选示意图，可进行参照，图10示出了采用“UE-基站-无线回传链路-锚点”，“UE-WiFi AP-无线回传链路-锚点”和“UE-锚点空口接入链路-锚点”三条传输路径为UE提供的多流传输组网。
显然除上述三种情况外，本发明实施例还可采用其他的数据传输路径进行数据多流传输，图11示出了目标数据传输路径架构的又再一种可选示意图，图12示出了目标数据传输路径架构的另又一种可选示意图，其中，图11所示为采用“UE-锚点空口接入链路-锚点”+“UE-基站-无线回传链路-锚点”为UE提供的多流传输组网，图12所示为采用“UE-锚点空口接入链路-锚点”+“UE-WiFi AP-无线回传链路-锚点”为UE提供的多流传输组网。值得注意的是，图10～图12所示的无线回传为点到多点传输技术，基站及WiFi AP只有一条回传链路，实际组网可以是点到点传输技术，可以是多条回传链路。
可选的，前文已述锚点所获取的UE至所述锚点之间的各条数据传输路径的资源可用性数据可以包括：各个接入节点与UE之间的空口接入链路资源数据，各接入节点与所述锚点之间的无线回传链路的资源数据，和UE与 锚点之间的锚点空口接入链路的资源数据。
可选的，在本发明实施例中，各接入节点可实时动态检测接入节点与UE之间的空口接入链路资源数据，经过预处理后，将处理后的链路资源数据上报到锚点；其中，空口接入链路资源数据可以包括：接入链路的可用带宽、拥塞情况等资源数据。对应的，接入节点为基站时，基站可实时动态检测UE与基站之间的空口接入链路资源数据，经过预处理后，实时将接入链路的可用带宽、拥塞情况等空口接入链路资源数据上报到决策点锚点；对应的，接入节点为WiFi AP时，WiFi AP可实时动态检测UE与WiFi AP之间的空口接入链路资源数据，经过预处理后，实时将接入链路的可用带宽、拥塞情况等空口接入链路资源数据上报到决策点锚点；
可选的，在本发明实施例中，各接入节点与所述锚点之间的无线回传链路的资源数据的获取方式可通过多种方式得到：一种方式是无线回传设备自身动态检测对应的无线回传链路状况，检测结果经处理后，将可用带宽、链路质量(如可用带宽、时延、抖动、丢包率等)等资源数据上报给锚点；另一种方法是通过接入节点(基站或WiFi AP)和锚点来检测接入节点和锚点之间的无线回传链路资源情况，并经预处理后，锚点可获取到预处理后的可用带宽、链路质量(如可用带宽、时延、抖动、丢包率等)等资源数据。
