背景技术
射频识别(radio frequency identification，RFID)是一种非接触式的自动识别技术，常称为感应式电子晶片或近接卡、感应卡、非接触卡、电子标签、电子条码等。RFID通过射频信号自动识别目标对象并获取相关数据，识别工作无须人工干预，作为条形码的无线版本，RFID技术具有条形码所不具备的防水、防磁、耐高温、使用寿命长、读取距离大、标签上数据可以加密、存储数据容量更大、存储信息更改自如等优点，其应用将给零售、物流等产业带来革命性变化。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如：长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)、第五代(5th generation，5G)系统、未来的第六代(6th generation，6G)或新无线(new radio，NR)等。
终端设备可以是一种向用户提供语音/数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制中的无线终端、 无人驾驶(self driving)中的无线终端、远程手术中的无线终端、智能电网中的无线终端、运输安全中的无线终端、智慧城市中的无线终端、智慧家庭中的无线终端、蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，5G网络中的终端设备或者公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等，本申请实施例对此并不限定。
接入网设备是RAN中的设备，或者说，是将终端设备接入到无线网络的RAN节点。例如，作为示例而非限定，作为接入网设备，可以列举：gNB、传输接收点(transmission reception point，TRP)、演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，Wifi)接入点(access point，AP)等。在一种网络结构中，接入网设备可以包括集中单元(centralized unit，CU)节点、或分布单元(distributed unit，DU)节点、或包括CU节点和DU节点的RAN设备、或者控制面CU节点(CU-CP节点)和用户面CU节点(CU-UP节点)以及DU节点的RAN设备。

宿主基站可以是一个具有完整基站功能的接入网网元，还可以是集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)分离的形态，即宿主节点由宿主基站的集中式单元和宿主基站的分布式单元组成。本文中，宿主节点的集中式单元也称为IAB donor CU(也可称作donor CU，或直接称为CU)。宿主节点的分布式单元也称为IAB donor DU(或称作donor DU)。其中donor CU还有可能是控制面(control plane，CP)和用户面(user plane，UP)(本文中简称为CU-UP)分离的形态。例如CU可由一个 CU-CP和一个或多个CU-UP组成。
下面对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
(一)IAB系统
1、基本概念
链路：是指一条路径中的两个相邻节点之间的路径。
接入链路：终端设备与基站之间，或者终端设备与IAB节点之间，或者终端设备与宿主节点之间，或者终端设备与宿主DU之间的链路。或者，接入链路包括某个IAB节点作为普通终端设备角色时和它的父节点进行通信时所使用的无线链路。IAB节点作为普通终端设备角色时，不为任何子节点提供回传服务。接入链路包括上行接入链路和下行接入链路。本申请中，终端设备的接入链路为无线链路，故接入链路也可被称为无线接入链路。
回传链路：IAB节点作为无线回传节点时与父节点之间的链路。IAB节点作为无线回传节点时，为子节点提供无线回传服务。回传链路包括上行回传链路，以及下行回传链路。本申请中，IAB节点与父节点之间的回传链路为无线链路，故回传链路也可被称为无线回传链路。
父节点与子节点：每个IAB节点将为其提供无线接入服务和/或无线回传服务的相邻节点视为父节点。相应地，每个IAB节点可视为其父节点的子节点。
可替换地，子节点也可以称为下级节点，父节点也可以称为上级节点。
节点的上一跳节点：是指在包含该节点的路径中的、在该节点之前最后一个接收到数据包的节点。可以理解为，节点的上一跳节点可以包括上行传输中该节点的上一跳节点，和下行传输中该节点的上一跳节点。
节点的下一跳节点：是指在包含该节点的路径中的、在该节点之后第一个接收到数据包的节点。可以理解为，节点的下一跳节点可以包括上行传输中该节点的下一跳节点，和下行传输中该节点的下一跳节点。
节点的入口链路：是指该节点与该节点的上一跳节点之间的链路，也可以称为节点的上一跳链路。可以理解为，节点的入口链路可以包括该节点在上行传输中的入口链路，和该节点在下行传输中的入口链路。
节点的出口链路：是指该节点与该节点的下一跳节点之间的链路，也可以称为节点的下一跳链路。可以理解为，节点的出口链路可以包括该节点在上行传输中的出口链路，和该节点在下行传输中的出口链路。
接入IAB节点：是指终端接入的IAB节点，或者说为终端设备提供接入服务的IAB节点。
中间IAB节点：是指为其它IAB节点(例如，接入IAB节点或其它中间IAB节点)提供无线回传服务的IAB节点。
路由选择：用于为数据包选择下一跳节点。
2、IAB节点的组成。
IAB节点可以具有移动终端(mobile terminal，MT)的部分以及DU的部分。IAB节点利用MT部分与其父节点进行通信，IAB节点利用DU部分与其子节点(子节点可能是终端或另一IAB节点)通信。一个IAB节点可以通过MT部分与该IAB节点的至少一个父节点之间建立回传连接。一个IAB节点的DU部分可以为终端或其他IAB节点的MT 部分提供接入服务。下面结合图2进行示例说明。
参见图2，图2为IAB节点的组成的示意图。UE通过IAB节点2和IAB节点1连接到宿主节点。其中，IAB节点1和IAB节点2均包括DU部分和MT部分。IAB节点2的DU部分为UE提供接入服务。IAB节点1的DU部分为IAB节点2的MT部分提供接入服务。宿主节点的DU部分为IAB节点1的MT部分提供接入服务。
为了便于理解，还需要对IAB网络的协议栈进行介绍。IAB网络的协议栈包括用户面协议栈和控制面协议栈。
3、接入IAB节点、中间IAB节点、Donor-DU、Donor-CU以及终端设备的协议栈架构。
接入IAB节点在用户面和控制面的协议栈不同，可分别参见图4和图5所示中的IAB节点1。
参见图3，图3为IAB系统的一种示例。如图3所示，IAB系统主要是由宿主节点和IAB节点组成，其中，IAB节点之间采用有向无环图的方式进行级联，并且在级联时，每个IAB节点可以进行非接入层(non access stratum，NAS)鉴权，以及通过协议数据单元(protocol data unit，PDU)会话完成操作维护管理(operation administration and maintenance，OAM)配置，宿主节点可以对其中所有的IAB节点进行管理。
需要说明的是，宿主节点和IAB节点分别是集中式节点和分布式节点中的一种示例，本申请可以运用于其他集中式节点和分布式节点组成的系统中。
参见图4，图4为多跳IAB网络的用户面协议栈架构的一种示例。如图4中所示，在图4所示的协议架构中，各个协议层的含义为：回传适配层(backhaul adaptation protocol，BAP)层、分组数据汇聚协议(packet data convergence protocol，PDCP)层、通用分组无线服务隧道协议用户面(general packet radio service tunneling protocol user plane，GTP-U)层、用户数据报协议(user datagram protocol，UDP)层、网络互连协议(internet protocol，IP)层、L2层(layer 2)、L1层(layer 1)、无线链路控制(radio link control，RLC)层、媒介接入控制(medium access control，MAC)层、物理(physical，PHY)层、无线资源控制(radio resource control，RRC)层、F1应用协议(F1application protocol，F1AP)层、流控制传输协议(stream control transmission protocol,SCTP)层。其中，L2层为链路层。示例性的，L2层可以为开放式通信系统互联(open systems interconnection，OSI)参考模型中的数据链路层。L1层可以为物理层。示例性的，L1层可以为OSI参考模型中的物理层。
其中，每个协议层都会被配置与之对应的协议层实体，例如PDCP实体，RLC实体以及MAC实体等。在上行传输中，UE的数据包(例如IP数据包)在PDCP层经过相应处理之后，依次经过RLC层，MAC层和PHY层发送给接入回传节点(例如图5中所示的IAB节点2)的PHY层。
当IAB节点作为无线终端的角色时，其与父节点之间的通信链路的协议栈与UE和接入IAB节点之间的无线接入链路的协议栈相同，其与宿主CU之间的协议栈与UE和宿主CU之间的协议栈相同。
另外，图4中还示出了宿主CU和接入IAB节点(如图4中的IAB节点2)之间的F1接口的用户面协议栈。F1接口通过GTP-U协议层建立的GTP-U隧道和UE的数据无线承载DRB是一一对应的。换句话说，一个UE的每个无线承载都有一个GTP隧道与之 一一对应。
参见图5，图5为多跳IAB网络的控制面协议栈架构的一种示例。图4中对各协议层的介绍在图5中也是适用的，但是也存在一些区别。例如，图5中接入IAB节点和宿主CU之间的F1接口采用的是F1控制面(F1-C)协议栈。
需要说明的是，图4和图5分别示出了IAB网络中传输UE的数据业务的端到端用户面和控制面协议栈架构一种示例。可选地，协议栈架构还可以有其它的可能性。例如，在IAB 2和宿主CU之间的F1接口引入用于安全保护的协议层，则协议栈架构会发生变化。
另外，若宿主节点是功能完整的实体，则IAB donor保留donor DU和donor CU对外部节点接口的协议栈即可，donor DU和donor CU之间的内部接口上的协议层不是必须的。类似地，IAB节点的协议栈，对外部而言，可以不区分DU部分和MT部分，只统一展示对外部节点接口的协议栈。
另外，不论是控制面的协议栈架构还是用户面的协议栈架构，在Donor-DU为Donor-CU和IAB节点之间的F1接口的代理节点时，Donor-DU中面向接入IAB节点的用户面协议栈架构中，在IP层之上，可以包括与接入IAB节点中的DU部分的协议栈架构中的UDP层和GTP-U层分别对等的UDP层和GTP-U层，还可以包含与接入IAB节点的DU部分对等的IPsec层；Donor-DU中面向接入IAB节点的控制面协议栈架构中，在IP层之上，可以包括与接入IAB节点中的DU部分的协议栈架构中的SCTP层和F1AP层分别对等的SCTP层和F1AP层，还可以包含与接入IAB节点的DU部分对等的IPsec层或DTLS层。
4、F1接口、F1接口的协议层
F1接口是指IAB节点的DU部分和宿主节点(或donor-CU或donor-DU)之间的逻辑接口，F1接口也可以称为F1*接口，支持用户面以及控制面。F1接口的协议层是指在F1接口上的通信协议层。
示例性的，F1接口的用户面协议层可以包括IP层、UDP层、GTP-U层中的一个或多个。可选的，F1接口的用户面协议层还包括PDCP层和/或IP安全(IP Security，IPsec)层。
示例性的，F1接口的控制面协议层可以包括IP层、F1AP层、SCTP层中的一个或多个。可选的，F1接口的控制面协议层还包括PDCP层、IPsec层和数据报文传输层安全(datagram transport layer security，简称DTLS)层中的一个或多个。
需要说明的是，IAB节点还可以支持Uu、E1、NG和X2等接口，此处为了简洁，不再赘述。
(二)无线射频
1、分离式无线射频
参见图6，图6为分离式无线射频(universal subscriber identity module，RFID)的一种示例。相对于传统的RFID架构，RFID分离架构可以将读写器分成接收器和激励器，原本读写器的接收链路包含在接收器，原来读写器的发送链路包含在激励器。参见图6，当接收器发送下行命令给RFID标签时，需要先发送给激励器，由激励器转发RFID标签，当RFID标签发送上行数据时，可以直接发送给接收器。
当采用RFID分离架构实现RFID标签盘点时，接收器发送的下行信令需要通过激励 器转发给RFID标签，因此在大范围的部署中，激励器可以存在多个，即接收器可以绑定多个激励器，并对这些激励器进行管理，并选择激励器转发下行管理命令。
2、激励器
在本申请中，激励器也可以称之为激励节点或Helper节点。激励器部署在IAB系统中的IAB节点，可以认为是IAB节点的上层功能模块，可以调用DU或MT的通讯接口进行通讯。
2、接收器
在本申请中，接收器也可以称之为接收节点或Receiver节点。接收器可以部署在IAB系统的IAB节点或宿主节点，同样地，接收器也可以被认为是IAB节点或宿主节点的上层功能模块，可以调用DU或MT的通讯接口进行通讯。
(三)网元
以下仅对部分相关的网元进行说明。
1、接入管理网元
要用于移动性管理和接入管理等，可以用于实现移动性管理实体(mobility management entity，MME)功能中除会话管理之外的其它功能，例如，合法监听以及接入授权/鉴权等功能。在5G通信系统中，该接入管理网元可以是接入管理功能(access and mobility management function，AMF)网元。在未来通信系统中，接入管理网元仍可以是AMF网元，或者，还可以有其它的名称，本申请不做限定。在本申请中，AMF网元可以负责IAB节点、激励器和接收器的相关授权。
2、认证服务器
用于鉴权服务、产生密钥实现对终端设备的双向鉴权，支持统一的鉴权框架。在5G通信系统中，该认证服务器可以是认证服务器功能(authentication server function，AUSF)网元。在未来通信系统中，认证服务器功能网元仍可以是AUSF网元，或者，还可以有其它的名称，本申请不做限定。
3、数据管理网元
用于处理终端设备标识，接入鉴权，注册以及移动性管理等。在5G通信系统中，该数据管理网元可以是统一数据管理(unified data management，UDM)网元，也可以是统一数据库功能(unified data repository，UDR)网元。在本申请中，也可以是RFID-H网元，该RFID-H网元可以是在核心网中新部署专用于负责RFID相关的网元，负责与RFID相关的认证、授权、盘点或标签读写代理等功能，与现有的核心网网元共同部署，也可以是作为现有核心网网元的功能模块负责RFID相关功能，本申请对此不作限定。
下面，结合图7至图11对本申请的流程进行详细说明。
本申请可以运用于任何集中式节点和分布式节点组成的系统，以下以IAB系统作为示例，不对本申请作出任何限定。
图7为IAB系统下部署接收器和激励器的一种示例。参见图7的(a)，接收器部署在宿主节点上，激励器A部署在IAB节点4上，激励器B部署在IAB节点5上。激励器A通过IAB节点1与接收器相连，激励器B通过IAB节点2与接收器相连，即，激励器A与激励器B都需要通过额外的1跳IAB节点才能与接收器相连，这样无疑会增加额外的时延开销。图7的(b)为通过调整图7的(a)得到的新拓扑，参见图7的(b)，IAB节点4与 IAB节点5皆直接与宿主节点相连，即激励器A与激励器B皆可与接收器直接通讯，图7的(b)的拓扑显然与图7的(a)的相比具有更小的时延。
在另一种可能的实现方式中，参见图7的(c)，此时，接收器部署在IAB节点1上，激励器A和激励器B还是部署在IAB节点4和IAB节点5上，激励器B未与接收器直接相连。图7的(d)为通过调整图7的(c)得到的新拓扑，此时，激励器B所在的IAB节点5与IAB节点1直接相连，即得到了更佳的路由拓扑。
图8示出了接收器部署在宿主节点上的情况下本申请的通信方法800的示意性流程。在方法800中，接收器部署在IAB节点(第二分布式节点中的一例)上，接收器部署在宿主节点(集中式节点中的一例)上。
在一种可能的实施方式中，S810，宿主节点(集中式节点中的一例)从AMF网元接收激励器的信息(第九信息中的一例)。
需要说明的是，当激励器部署在IAB节点上时，该激励器的信息可以是部署激励器的IAB节点的信息。
AMF网元向宿主节点发送激励器的信息，可以当AMF网元进行激励器授权时发送给宿主节点，也可以当AMF网元进行IAB节点授权时将IAB节点信息和激励器信息一起发送给宿主节点，即在IAB场景下，当IAB功能授权通过后，AMF网元可以通过N2消息发送IAB授权指示给宿主节点，AMF网元同样可以在N2消息中携带激励器信息给宿主节点。
S820，宿主节点根据信息#1(第一信息中的一例)确定接收器和激励器之间的拓扑#1(第一拓扑中的一例)。
其中，信息#1可以包括接收器的状态信息和/或激励器的状态信息。接收器的状态信息可以是以下信息中的至少一项：所述接收器的负载信息，所述接收器支持最大激励器的数量信息。激励器的状态信息可以是激励器的位置信息。
当宿主节点是通过调整原来的拓扑#2(第二拓扑中的一例)获得拓扑#1时，信息#1可以包括拓扑#2的信息。例如，拓扑#2的信息可以是接收器和激励器之间的间隔节点数，接收器和激励器之间的链路负载，接收器和激励器之间的链路质量或接收器和激励器之间的冗余路径。
例如，宿主节点根据接收器和激励器之间的平均的间隔节点数确定拓扑#1，或者是部分激励器和接收器之间的间隔节点数确定拓扑#1。
再例如，宿主节点根据接收器和激励器之间的平均链路负载，或者最大链路负载，或者部分链路之间的负载确定拓扑#1。
再例如，宿主节点根据每条链路的链路质量，或者所有链路中最差的链路质量确定拓扑#1，其中，链路质量可以是平均链路质量，或者历史瞬时最差链路质量，也可以用丢包率、时延、抖动等特性去衡量链路质量。
以上关于信息#1的描述仅作示例，在本申请中，宿主节点可以将对拓扑有影响的因素都作为信息#1，本申请不作限定。
需要说明的是，宿主节点根据信息#1确定接收器和激励器之间的拓扑#1，可以理解为宿主节点根据信息#1确定激励器和预先配置好的接收器之间的拓扑#1，也可以理解为宿主节点根据信息#1选择接收器和激励器并确定该接收器和激励器之间拓扑关系。即， 当宿主节点确定拓扑#1时，可以仅通过确定接收器和激励器之间的拓扑连接关系获得较优的拓扑#1，也可以在确定拓扑#1时既选择合适的接收器和激励器，又确定该接收器和激励器之间的拓扑连接关系获得较优的拓扑#1。
当宿主节点确定拓扑#1的同时还确定了接收器和/或激励器时，宿主节点还可以将接收器和激励器进行绑定，宿主节点中的接收器绑定激励器的表现形式可以是构建接收器标识与激励器标识之间的映射关系。需要说明的是，当接收器部署在宿主节点上时，可以用宿主节点标识代替接收器标识。当激励器部署在IAB节点上时，也可以用IAB节点标识代替激励器标识，其中IAB节点标识可以为移动终端(mobile termination，MT)标识(例如小区无线网络临时标识(cell radio network temporary identity，C-RNTI)、5G临时移动用户标识(5G-serving-temporary mobile subscriber identity，5G-S-TMSI))或者DU标识(例如无线网络层/传输网络层标识(ratio network layer/transport network layer identity,RNL/TNL ID))。
需要说明的是，当接收器部署在宿主节点上时，宿主节点和接收器之间的通讯可以通过内部接口进行，例如，宿主节点将接收器和激励器绑定完成后，可以将绑定信息和激励器信息通过内部接口发送给接收器，例如可以通过F1-C/F1-U/RRC消息发送给接收器。
S830，宿主节点向接收器发送信息#2(第二信息中的一例)，信息#2用于指示拓扑#1。
可选的，信息#2包括激励器和接收器的绑定信息，或者包括激励器的标识信息。示例性的，绑定信息可以通过多种方式标识，例如通过在一个信元、或一个消息、或一个数据结构中包括接收器的标识和激励器的标识来表示该信元、或该消息、或该数据结构中的接收器和激励器绑定。即，宿主节点可以将激励器和接收器的绑定信息，或者说是激励器标识和接收器标识之间的映射关系发送给接收器，也可以仅将激励器的标识发送给接收器，接收器默认绑定所指示的激励器。

可选地，接收器可以根据该信息#2主动与激励器建立连接。
可选的，接收器可以根据该信息#2调整接收器上的拓扑信息。
需要说明的是，拓扑#1可以是接收器与激励器直接连接的形式，也可以是激励器通过中间的节点与接收器连接的形式，即，激励器与接收器进行绑定可以理解为接收器与该负责管理的激励器形成映射关系，而并非理解成接收器与激励器直接相连。

其中，构建链路并配置路由的具体过程可以与现有技术相似，这里，为了避免赘述， 省略其详细说明。
以下结合图7的(a)和(b)作示例性说明，宿主节点可以根据接收器的负载信息、接收器支持激励器的最大数量信息或激励器A和激励器B的位置信息确定将接收器与激励器A和激励器B进行绑定并形成图7的(b)的拓扑形式，或者，当接收器、激励器A和激励器B已经处于图7的(a)的拓扑形式，宿主节点也可以根据该拓扑的相关信息将该拓扑调整成为图7的(b)的拓扑形式。当宿主节点确定图7的(b)的拓扑形式时，宿主节点通过内部接口将接收器与接收器A和接收器B的绑定信息发送给接收器，当激励器A和激励器B未预设值接收器的相关信息时，宿主节点将接收器的标识信息发送给激励器A和激励器B。从而，接收器与激励器A和激励器B后续可以按照该拓扑进行通信。以上仅作理解性说明，不对本申请作出任何限定。
根据本申请的实施例，将激励器部署在IAB节点上，接收器部署在宿主节点上，宿主节点可以集中管理接收器和接收器，可以根据接收器的状态信息和/或激励器的状态信息来确定或者调整接收器和激励器之间的拓扑，接收器和激励器按照该拓扑进行通信，即，接收器和激励器之间的绑定关系并非静态配置，宿主节点可以灵活的调整哪些接收器与哪些激励器绑定，以及接收器与激励器之间如何进行通讯。
图9示出了接收器部署在IAB节点上的情况下本申请的方法900的示意性流程。在方法900中，激励器部署在IAB节点#1(第一分布式节点中的一例)上，接收器部署在IAB节点#2(第二分布式节点的一例)上。
在一种可能的实现方式中，S910，宿主节点从AMF网元接收激励器信息(第九信息中的一例)。

在一种可能的实现方式中，S920，宿主节点从AMF网元接收接收器信息(第六信息中的一例)。
需要说明的是，当接收器部署在IAB节点#2上时，该接收器的信息可以是部署接收器的IAB节点#2的信息。
AMF网元向宿主节点发送接收器的信息，可以当AMF网元进行接收器授权时发送给宿主节点，也可以当AMF网元进行IAB节点#2授权时将IAB节点#2的信息和激励器信息一起发送给宿主节点，即在IAB场景下，当IAB功能授权通过后，AMF网元通过N2消息发送IAB授权指示给宿主节点，AMF网元同样可以在N2消息中携带接收器信息给宿主节点。
S930，宿主节点根据信息#A(第一信息中的另一例)确定激励器和接收器之间的拓扑#A(第一拓扑中的另一例)。
其中，宿主节点根据信息#A确定激励器和接收器之间的拓扑#A的过程与方法800中宿主节点根据信息#1确定激励器和接收器之间的拓扑#1的过程类似，在此不再赘述。
需要说明的是，在方法900中，激励器和接收器都是部署在IAB节点，当宿主节点需要构建接收器和激励器的映射关系时，表现形式可以是构建接收器标识与激励器标识之间的映射关系，也可以用IAB节点#1的标识代替激励器的标识，用IAB节点#2的标识代替接收器的标识，其中IAB节点的标识可以为MT标识(例如C-RNTI、5G-S-TMSI)或者 DU标识(例如RNL/TNL ID)。

在一种可能的实现方式中，S950，宿主节点向激励器发送接收器的标识信息(第三信息中的另一例)。
可选地，当接收器的相关信息并没有预先配置在激励器上，宿主节点可以将接收器的标识信息，或者，接收器的标识信息和位置信息发送给激励器。其中，关于标识信息和位置信息的描述与上述描述类似，在此不再赘述。
可选地，宿主节点接收到接收器的标识信息后，也可以将激励器的信息发送给该接收器，然后接收器可以主动与激励器建立连接。
其中，当激励器和接收器都是部署在IAB节点上时，向接收器发送的信息#B和向激励器发送的接收器的标识信息都可以通过F1-C、F1-U或者RRC消息发送。
需要说明的是，在IAB系统中，IAB节点会默认将信息发送给宿主节点，因此，宿主节点可以更新激励器，接收器以及中间相关节点的BAP路由，以保证接收器和激励器之间能够正常的通讯。后续激励器和接收器之间的通讯可以通过BAP层寻址，基于IP地址进行通讯。
根据本申请的实施例，将激励器和接收器部署在IAB节点上，宿主节点可以集中管理激励器和接收器，可以根据接收器的状态信息和/或激励器的状态信息来确定或者调整接收器和激励器之间的拓扑，接收器和激励器按照该拓扑进行通信，即，接收器和激励器之间的绑定关系并非静态配置，宿主节点可以灵活的调整哪些接收器与哪些激励器绑定，以及接收器与激励器之间如何进行通讯。
方法800和方法900皆是将激励器和接收器部署在IAB系统的节点中，其中，IAB节点需要请求AMF网元获得授权，因此部署激励器的IAB节点同样可以请求AMF网元获得激励器授权。作为示例而非限定，图10给出了激励器授权过程的方法1000的一例示意性流程。
如图10所示，方法1000可以包括：S1010至S1060，其中S1010为可选操作。本申请实施例执行完操作S1010至S1060后可以执行方法800和方法900的操作。
方法1000可以运用于激励器部署在IAB节点的方案。
可选地，S1010，宿主节点发送广播信息，该广播信息用于指示激励器选择父节点。
激励器接收广播信息，当部署了激励器的IAB节点在级联时，可以参考宿主节点广播的信息，部署激励器的IAB节点在选择父节点(DU选择)时，可以优先选择广播信息指示的父节点。
例如，当接收器部署在宿主节点上时，该广播信息中包括宿主节点具备接收器能力的信息，激励器收到信息后，选择具备接收器能力的宿主节点作为父节点，此时，可以优化局部接收器和激励器的绑定拓扑，减少方法800和方法900中确定拓扑关系操作的复杂度。
S1020，激励器向宿主节点发送信息#a(第七信息中的一例)，信息#a中包括激励器的授权能力信息，信息#a用于指示宿主节点选择AMF网元#a(第二AMF网元中的一例)。

需要说明的是，宿主节点可以对部署激励器的IAB节点进行IAB配置，配置的操作过程可以与现有技术类似，不同的地方在于，可以在RRC消息(例如RRC setup request或UL RRC transfer)中携带激励器的标识，其中，激励器的标识也可以用现有的RAN ID代替，具体过程在此不再赘述。
S1030，宿主节点根据信息#a选择AMF网元#a，该AMF网元#a支持激励器授权，可以用于后续执行IAB授权以及激励器授权的流程。

需要说明的是，信息#a和信息#b可以相同，也可以不同，例如信息#b可以是基于信息#a生成的。
S1050，AMF网元#a根据信息#b以及IAB签约信息判定是否授权IAB节点。
当AMF网元#a接收到信息#b后，根据从UDM网元或UDR网元中获取的IAB节点签约信息和/或本地策略决定是否授权IAB功能。此操作可以与现有技术类似，在此不再赘述。
S1060，AMF网元#a根据信息#b判定是否授权激励器。其中AMF网元#a判定是否授权的方式包括但不限于以下方式：
方式1
当AMF网元#a接收到信息#b后，根据从UDM网元或UDR网元中获取的激励器签约信息决定是否允许授权激励器功能。

从而，在本申请的实施例中，在IAB节点的授权过程中，可以同步执行激励器的授权，从而可以使IAB节点获取启用/使用激励器能力的权限。
在方法900中，接收器部署在IAB节点上，其中，IAB节点需要请求AMF网元获得授权，因此部署接收器的IAB节点同样可以请求AMF网元获得接收器授权。作为示例而非限定，图11给出了接收器授权过程的方法1100的一例示意性流程。
如图11所示，方法1100可以包括：S1110至S1160，其中S1110为可选操作。本申请实施例执行完后可以执行方法900的操作。
需要说明的是，方法1100的接收器授权过程与方法1000的激励器授权过程类似，因此以下为了简洁，仅简要描述接收器授权过程。
