Description

信息传输的方法、装置和系统
本申请要求于2020年07月30日提交中国国家知识产权局、申请号为202010751732.X、申请名称为“信息传输的方法、装置和系统”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
本申请涉及通信领域，并且更具体地，涉及一种信息传输的方法、装置和系统。
背景技术
相较于第四代移动通信系统，第五代移动通信(5th generation mobile networks，5G)针对网络各项性能指标，全方位的都提出了更严苛的要求。例如，容量指标提升1000倍，更广的覆盖需求、超高可靠超低时延等。考虑到高频载波频率资源丰富，在热点区域，为满足5G超高容量需求，利用高频小站组网愈发流行。高频载波传播特性较差，受遮挡衰减严重，覆盖范围不广，故而需要大量密集部署小站；为这些大量密集部署的小站提供光纤回传的成本高，施工难度大，尤其是偏远地区。
接入回传一体化(integrated access and backhaul,IAB)技术为解决上述问题提供了思路，其接入链路(access link)和回传链路(backhaul link)皆采用无线传输方案，可以避免光纤部署。在IAB网络中，中继节点(relay node，RN)可以称为IAB节点，可以为用户设备(user equipment，UE)提供无线接入服务，UE的业务传输由IAB节点通过无线回传链路连接到的IAB宿主节点(donor node)传输，宿主节点也称为宿主基站(donor gnodeB，DgNB)。
目前，IAB节点获取操作、管理和维护(operation,administration and maintenance，OAM)业务可以通过IAB节点与核心网实体之间的协议数据单元(protocol data unit，PDU)会话从OAM实体获取OAM业务，但是如何从网络管理设备侧获取，标准上没有进行具体的定义。

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。
本申请实施例可以应用于各种通信系统，例如无线局域网系统(wireless local area network，WLAN)、窄带物联网系统(narrow band-internet of things，NB-IoT)、全球移动通信系统(global system for mobile communications，GSM)、增强型数据速率GSM演进系统(enhanced data rate for gsm evolution，EDGE)、宽带码分多址系统(wideband code division multiple access，WCDMA)、码分多址2000系统(code division multiple access，CDMA2000)、时分同步码分多址系统(time division-synchronization code division multiple access，TD-SCDMA)，长期演进系统(long term evolution，LTE)、卫星通信、第五代(5th generation，5G)系统或者将来出现的新的通信系统等。
本申请实施例中所涉及到的终端设备可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备。终端可以是移动台(mobile station，MS)、用户单元(subscriber unit)、用户设备(user equipment,UE)、蜂窝电话(cellular phone)、智能电话(smart phone)、无线数据卡、个人数字助理(personal digital assistant，PDA)电脑、平板型电脑、无线调制解调器(modem)、手持设备(handset)、膝上型电脑(laptop computer)、机器类型通信(machine type communication，MTC)终端等。
相较于第四代移动通信系统，第五代移动通信(5th generation mobile networks，5G)针对网络各项性能指标，全方位的都提出了更严苛的要求。例如，容量指标提升1000倍，更广的覆盖需求、超高可靠超低时延等。考虑到高频载波频率资源丰富，在热点区域，为满足5G超高容量需求，利用高频小站组网愈发流行。高频载波传播特性较差，受遮挡衰减严重，覆盖范围不广，故而需要大量密集部署小站；为这些大量密集部署的小站提供光纤回传的成本高，施工难度大，尤其是偏远地区。
接入回传一体化(integrated access and backhaul,IAB)技术为解决上述问题提供了思路，其接入链路(access link)和回传链路(backhaul link)皆采用无线传输方案，可以避免光纤部署。如图1所示，出示了无线中继场景示意图。在IAB网络中，中继节点(relay node，RN)可以称为IAB节点，可以为用户设备(user equipment，UE)提供无线接入服务，UE的业务传输由IAB节点通过无线回传链路连接到的IAB宿主节点(donor node)传输，宿主节点也称为宿主基站(donor gnodeB，DgNB)。IAB节点可以扮演移动终端(mobile termination，MT)和分布式单元(distributed unit，DU)两个角色；当IAB节点面向其父节点时，其可以被视为终端设备，即MT的角色，其中父节点可能是宿主基站；当IAB节点面向其子节点时，该IAB节点可以被视为网络设备，即DU的角色，其中，子节点可能是另一IAB节点或者普通UE。宿主基站可以是一个具有完整基站功能的接入网网元，可以是集中式单元(centralized unit，CU)和分布式单元分离形态的接入网网元。为了便于表述，将宿主基站的集中式单元简称为donor CU或者直接称为CU，宿主基站的分布式单元简称为donor DU或者直接称为DU，其中donor CU还有可能是控制面(control plane，CP)和用户面(user plane，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。宿主基站连接到为UE服务的核心网网元，例如连接到5G核心网，为IAB节点提供无线回传功能。
目前，IAB节点获取操作、管理和维护(operation,administration and maintenance，OAM)业务可以通过IAB节点与核心网实体之间的协议数据单元(protocol data unit，PDU)会话从OAM实体获取OAM业务，IAB节点与其OAM实体之间的传输连接使用IP协议，由IAB-MTs PDU会话通过5G网络提供，或者当IAB-MT使用EN-DC时，由IAB-MTs PDN连接通过LTE网络提供，但是标准上对网络管理设备侧具体的传输没有定义；也没有说明新的5G服务质量指示(5g quality of service indicator，5QI)具体如何定义。另外，IAB节点可以通过回传链路从OAM实体直接获取OAM业务，但是具体的传输方式在协议中没有体现。
OAM业务包括：接收命令，例如故障管理(fault management，FM)、配置管理(configuration management，CM)、性能管理(performance management，PM)相关的操作信息命令；配置数据；软件下载，例如用于设备软件升级；告警；性能指标信息等。其中，告警会产生高优先级的流量的突发，但不需要实时传输。OAM实体向IAB节点发送的配置数据信息也会产生少量的突发流量，其优先级低于告警，但是仍然对时延敏感。
为了方便对本申请实施例的理解，如图2所示，出示了适用于IAB节点的网络架构示意图。其中，IAB宿主节点(IAB-Donor gNB)为通过无线连接能够为IAB节点服务的基站。IAB-Donor gNB由IAB-Donor-CU和一个或多个IAB-Donor-DU组成。在gNB-CU-CP和gNB-CU-UP分离的情况下，IAB-donor gNB可以由一个IAB-donor-CU-CP、多个 IAB-donor-CU-UP和多个IAB-donor-DU组成。
