具体实施方式
本申请实施例提供了数据处理方法及装置，用以使得5G网络中存在无线回程时，可以在各跳无线节点上正确进行数据承载的可靠传输，以满足后续的终端服务和数据传输的需求，提高了系统管理效率。
本申请实施例提出了一种综合接入及回程(Integrated Access and Backhaul，IAB)网络的适配层处理方法，以保证在简化协议栈的前提下，能够正确地完成适配层在网络侧的配置，为用户设备(UE)提供稳定可靠的数据传输服务。
5G移动通信系统介绍如下：
参见图1，在5G系统中，网络侧的节点之间大多进行有线连接，即基站 (gNB)之间通过有线链路连接，gNB(NR NodeB)和核心网节点，例如接入和移动管理功能实体(Access and Mobility Management Function，AMF)，用户面功能实体(User Plane Function，UPF)等，二者之间也是采取有线链路连接。图1中的ng-eNB为一种基站(node providing E-UTRA user plane and control plane protocol terminations towards the UE,and connected via the NG interface to the 5GC)。
5G无线协议架构介绍如下：
5G基本用户平面协议层包括：业务数据适应协议(Service Data Adaptation Protocol，SDAP)，分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)，无线链路控制(Radio Link Control，RLC)和媒体访问控制(Media Access Control Address，MAC)，端口物理层(Port Physical Layer，PHY)。控制平面协议层包括：非接入层(Non-access stratum，NAS)，无线资源控制(Radio Resource Control，RRC)，PDCP，RLC，MAC和PHY。用户平面和控制平面的协议栈架构分别如图2和图3所示。
一种简化协议栈的IAB控制面架构如图4A、图4B和图4C所示。
图4A中，来自UE的RRC消息，将直接映射到IAB节点(node)的信令承载上，其中需要添加适配层信息；
图4B中，来自UE的RRC消息，将直接映射到上一跳IAB node的信令承载上，其中需要添加适配层信息；
图4C中，来自IAB node的分布式单元(Distributed Unit，DU)部分的F1AP消息，将映射到该IAB node的信令承载上。
图4A、图4B和图4C中的MT为移动终端(Mobile Terminal)、CU-CP为中央单元控制平面(Centric Unit-Control plane)、IAB-donor为宿主IAB。
本申请实施例提供了针对多跳5G无线回程节点适配层的处理方法，以满足为用户提供稳定的信令数据传输服务的需求，并使得协议栈尽量简化。
当宿主(Donor)DU接收到中间IAB节点(最后一跳与第一跳之间的IAB节点)的初始数据包，通过解析适配层，获取其中IAB-无线网络临时标识(Radio  Network Tempory Identity，RNTI)ID，并将其包含在第一跳IAB节点对应的F1AP消息中，例如：上行链路UL RRC信息传输(message transfer)消息，并发送给第一跳IAB对应的Donor CU-CP实体(一个CU-CP逻辑实体可以包含一个或多个实体)。
Donor中央单元(centric unit，CU)需要选择针对中间IAB节点(子节点)F1AP的Donor CU-CP实体并发起相应的UE上下文(context)建立过程。该过程中的UE context建立请求消息中需携带指示域(indicator)指示Donor DU对应的上下文属于IAB node，使IAB node激活相应的功能，例如适配层等功能，此外UE context建立请求消息中还需要包含IAB-RNTI ID。
在控制平面CP和功能平面UP分离场景下，Donor CU可进一步分为宿主中央单元控制平面Donor CU-CP和宿主中央单元功能平面Donor CU-UP。
Donor CU-CP发送给IAB子节点的无线资源控制(Radio Resource Control，RRC)建立消息中需携带IAB父节点分配的IAB-RNTI ID，使IAB父节点后续添加适配层时，可作为寻址路由使用。
下面介绍几个实施例的举例说明。
实施例1、第一跳IAB节点的信令配置流程，参见图5，包括：
步骤1：第一跳IAB node作为UE开机与网络建立RRC连接，即IAB节点先以普通UE的身份，与网络通讯，建立RRC连接，此时由Donor DU选择合适的Donor CU-CP实体为IAB node提供F1AP的信令服务，Donor CU-CP实体将保存IAB node作为UE的标识C-RNTI ID，并完成相应的RRC建立过程(通过IAB的上下行链路(UL/DL)上的RRC message transfer消息)。
步骤2：Donor CU-CP实体发起UE context建立过程(建立信令无线承载(SRB)2和OAM的数据无线承载(DRB for OAM))，其中，UE context建立请求消息中需携带indicator指示Donor DU，该UE为IAB node，使得宿主分布式单元Donor DU针对该IAB node的数据包可以应用适配层等功能。
步骤3：IAB node，需要从OAM配置参数中获取该IAB节点标识，该IAB节点标识在每个Donor CU下唯一。
步骤4：IAB node将激活针对该IAB节点的分布式单元DU部分的F1AP和SRB信令传输通道，这里，需要使该IAB的DU能够将F1AP数据包，通过MT部分的特定SRB，例如SRB1，传送给Donor CU-CP；也能使该IAB的DU，能够将来自UE的SRB数据包，通过该IAB节点的移动终端MT部分的特定SRB，例如SRB1/2/3等，传送给该IAB节点的Donor。
需要说明的是，每个IAB节点包含分布式单元DU和移动终端MT两部分。
步骤5：当IAB node试图与Donor CU-CP建立F1连接时，提供该IAB节点的相关的IAB节点标识给Donor CU-CP。
步骤6：UE通过IAB node，与Donor(包括Donor CU-CP和Donor DU)进行信令传输。
步骤7：IAB node与Donor CU-CP之间进行信令传输，该信令即UE正常通信需要交互的F1信令。
实施例2、UE信令承载在中间IAB节点的适配层配置流程，参见图6，包括：
步骤11：当中间节点IAB node 1作为UE，开机与网络建立RRC连接，此时作为父节点的IAB node 2的DU部分将为此UE分配一个该IAB node(即IAB node 2)内唯一的标识，例如IAB-RNTI ID，并将此IAB-RNTI ID信息包含在适配层中(可选的，或包含在F1AP消息中)。
步骤12：当Donor DU接收到含有该IAB-RNTI ID的数据包，通过解析适配层，获取其中的IAB-RNTI ID，并将该IAB-RNTI ID包含在IAB node 2对应的F1AP消息中，例如：UL RRC message transfer消息，并发送给相应的Donor CU-CP实体。
步骤13：相应的Donor CU-CP实体接收到IAB node 1作为UE发起的RRC建立消息后，保存IAB node 1作为UE的标识IAB-RNTI ID，并完成相应的RRC建立过程(通过IAB2的UL/DL RRC message transfer消息)，可选地，RRC建立消息中携带该IAB-RNTI ID。
步骤14：Donor CU-CP选择出针对IAB1F1AP的Donor CU-CP实体并发起针对IAB node 1的UE context建立过程，通知Donor DU建立针对IAB node 1的上下文信息，包含该IAB-RNTI ID，携带指示域indicator指示Donor DU，该UE为IAB node，Donor DU针对该IAB的数据包可以应用适配层等功能；
步骤15：IAB node1，需要建立PDU会话(session)来下载OAM的相关配置参数，因此Donor CU-CP实体将发起针对IAB node 2的UE context setup过程，此信息以容器container形式包含在IAB node 2的RRC消息中，并通过相应的F1AP和SRB传送给IAB node 2；
待收到UE context setup响应后，将构建RRC重配置(reconfiguration)消息，并通过IAB node 1的F1AP传送给Donor DU，随后由IAB node 2传送给IAB node 1的MT部分，完成对SRB2和DRB for OAM的配置。
步骤16：IAB node 1从OAM配置参数中获取该IAB节点标识，该标识在每个Donor CU下唯一。
步骤17：IAB node 1将激活针对Donor DU部分的F1AP信令/SRB信令传输通道，这里，需要使该IAB的DU，能够将F1AP数据包，通过MT部分的特定SRB,例如SRB1，传送给Donor，或能够将来自UE的SRB数据包(例如SRB1)，通过MT部分的特定SRB，例如SRB1，传送给Donor。
注：该步骤17也可能在步骤11后执行。
步骤18：当IAB node 1试图与Donor CU-CP实体建立F1连接时，提供相关的IAB节点标识给Donor CU-CP实体，在构建适配层时，可将此IAB节点标识加入适配层，同时添加IAB-RNTI ID；
步骤19：在Donor DU通过适配层的IAB-RNTI ID找寻到对应IAB node 1的上下文，同时，采用F1AP过程，如IAB node 1的UL RRC信息传输(message transfer)消息将此信令包传送给对应的Donor CU-CP实体。
步骤20：对应的Donor CU-CP实体，通过PDCP/RRC处理单元，解析出相应的F1消息，并交给F1接入点(AP)处理。
需要说明的是，F1AP/RRC/PDCP这些都是构成Donor CU-CP的主要功能 实体。
