下面结合附图介绍本公开的实施例。本公开实施例提供的信息传输方法、装置、网络设备及终端设备可以应用于无线通信系统中。该无线通信系统可以为采用第五代(5th Generation,5G)移动通信技术的系统(以下均简称为5G系统),所述领域技术人员可以了解,5G新空口(New Radio,NR)系统仅为示例,不为限制。The following describes embodiments of the present disclosure with reference to the accompanying drawings. The information transmission method, device, network equipment and terminal equipment provided by the embodiments of the present disclosure can be applied in wireless communication systems. The wireless communication system may be a system using the fifth generation (5th Generation, 5G) mobile communication technology (hereinafter referred to as the 5G system). Those skilled in the field can understand that the 5G New Radio (NR) system is only Examples, not limitations.
首先对与本公开实施例相关的一些概念进行说明如下。First, some concepts related to the embodiments of the present disclosure are described as follows.
1、集成接入和回程(Integrated Access and Backhaul,IAB)架构1. Integrated Access and Backhaul (IAB) architecture
IAB是5G无线接入网(NG-RAN)内的无线中继技术,中继节点(被称为IAB node)支持通过NR的接入和回传。回传的终止节点被称为IAB锚点(IAB donor),该节点是支持IAB的gNB。IAB架构如图1所示。IAB is a wireless relay technology within the 5G radio access network (NG-RAN). The relay node (called IAB node) supports access and backhaul through NR. The terminating node of the backhaul is called the IAB anchor (IAB donor), which is a gNB supporting IAB. The IAB architecture is shown in Figure 1.
IAB锚点包括一个IAB锚点控制单元(IAB-donor-CU)和一个或多个IAB 锚点分布单元(IAB-donor-DU),IAB节点通过NR Uu接口的用户设备(User Equipment,UE)功能连接上游IAB节点或IAB-donor-DU。IAB节点通过NR Uu接口的网络功能为下游IAB节点和UEs提供无线回传。The IAB anchor includes an IAB anchor control unit (IAB-donor-CU) and one or more IAB Anchor distribution unit (IAB-donor-DU), the IAB node connects to the upstream IAB node or IAB-donor-DU through the user equipment (User Equipment, UE) function of the NR Uu interface. The IAB node provides wireless backhaul to downstream IAB nodes and UEs through the network functions of the NR Uu interface.
2、IAB node的广播消息2. Broadcast message of IAB node
系统信息块一(System Information Block 1,SIB1)消息中,包含小区接入相关信息(cellAccessRelatedInfo),该cellAccessRelatedInfo中包含公共陆地移动网标识信息列表(plmn-IdentityInfoList),该plmn-IdentityInfoList中包含可选参数:是否支持IAB的标识(iab-Support-r16)。The System Information Block 1 (SIB1) message contains cell access related information (cellAccessRelatedInfo). The cellAccessRelatedInfo contains a public land mobile network identification information list (plmn-IdentityInfoList). The plmn-IdentityInfoList contains optional Parameters: Whether to support the IAB logo (iab-Support-r16).
3、5G核心网(5GC)网络功能实体(Network Function,NF)3. 5G core network (5GC) network function entity (Network Function, NF)
5GC NF(如策略控制功能实体(Policy Control Function,PCF)或接入和移动管理功能(Access and Mobility Management Function,AMF))决定移动基站中继选择策略,并将该策略提供给UE或锚点无线接入网络(Radio Access Network,RAN)节点。UE或锚点RAN节点根据该策略选择移动基站中继。5GC NF (such as Policy Control Function (PCF) or Access and Mobility Management Function (AMF)) determines the mobile base station relay selection strategy and provides the strategy to the UE or anchor point Radio Access Network (RAN) node. The UE or anchor RAN node selects the mobile base station relay according to this policy.
当锚点RAN节点负责选择移动基站中继时,锚点RAN节点做出拓扑适应决策,并触发拓扑适应过程。When the anchor RAN node is responsible for selecting the mobile base station relay, the anchor RAN node makes a topology adaptation decision and triggers the topology adaptation process.
当UE负责选择移动基站中继时,UE可通过下述方式触发移动基站中继的删除,增加或改变。When the UE is responsible for selecting the mobile base station relay, the UE can trigger the deletion, addition or change of the mobile base station relay in the following ways.
1.UE向锚点RAN发送喜好指示(如期望使用/不使用基站中继),锚点RAN决定是否接受UE接入请求,锚点RAN的决策依据UE注册通过锚点RAN注册时,网络下发给锚点RAN的策略。若UE请求通过中继基站接入,则UE通过锚点RAN节点接入到网络,由AMF决定UE是否允许通过中继基站接入。1. The UE sends a preference indication (such as the desire to use/not use the base station relay) to the anchor RAN, and the anchor RAN decides whether to accept the UE access request. The anchor RAN's decision-making is based on the UE registration. When registering through the anchor RAN, the network downloads The policy sent to the anchor RAN. If the UE requests access through the relay base station, the UE accesses the network through the anchor RAN node, and the AMF determines whether the UE is allowed to access through the relay base station.
2、UE通过非接入(Non-Access Stratum,NAS)消息向AMF提供网络喜好指示,UE可在消息中包括期望使用/不使用基站中继,基站中继的标识以及测量结果等信息。AMF根据策略,UE签约,上述基站中继的信息(如负载)等信息决定是否接受UE的请求,并将此结果返回给UE。2. The UE provides network preference instructions to the AMF through the Non-Access Stratum (NAS) message. The UE can include information such as the desired use/non-use of the base station relay, the identification of the base station relay, and measurement results in the message. The AMF decides whether to accept the UE's request based on the policy, UE subscription, the above base station relay information (such as load), and returns the result to the UE.

一种情况下,核心网节点可以在注册接受消息中携带终端的第一策略信息,所述第一策略信息包括:允许终端接入的中继节点的标识信息。In one case, the core network node may carry the first policy information of the terminal in the registration acceptance message, where the first policy information includes: identification information of the relay node that allows the terminal to access.

The relay node indicated in the identification information of the relay node is accessed to ensure the reliability of the access.
还需要说明的是,第一中继节点可以通过采用如下方式实现向核心网节点发送第一信息:It should also be noted that the first relay node can send the first information to the core network node in the following manner:
接收终端通过第二中继节点发送的非接入层NAS消息,所述NAS消息中携带终端的注册请求;Receive a non-access layer NAS message sent by the terminal through the second relay node, where the NAS message carries the registration request of the terminal;
根据所述NAS消息,向核心网节点发送第一信息,所述第一信息中包括终端的注册请求和所述第二中继节点的标识信息,所述第二中继节点为所述终端连接到所述第一中继节点之前所经过的节点。According to the NAS message, the first information is sent to the core network node. The first information includes the registration request of the terminal and the identification information of the second relay node. The second relay node is connected to the terminal. The node passed before reaching the first relay node.
可选地,所述向核心网节点发送第一信息的实现方式包括如下方式中的一项:Optionally, the implementation method of sending the first information to the core network node includes one of the following methods:
方式一、在所述NAS消息中还携带所述第二中继节点的标识信息的情况 下,向所述核心网节点转发所述NAS消息,所述NAS消息中包括所述第一信息;Mode 1: The NAS message also carries the identification information of the second relay node forwarding the NAS message to the core network node, where the NAS message includes the first information;
需要说明的是,在此种情况下,终端向第一中继节点发送的NAS消息中便携带第一信息,第一中继节点只需将该NAS消息转发给核心网节点即可。It should be noted that in this case, the NAS message sent by the terminal to the first relay node carries the first information, and the first relay node only needs to forward the NAS message to the core network node.
可选地,终端可以采用如下方式中的一项获取所述第二中继节点的标识信息:Optionally, the terminal may acquire the identification information of the second relay node in one of the following ways:
B11、接收第二中继节点的广播消息,所述广播消息中携带所述第二中继节点的标识信息;B11. Receive a broadcast message from the second relay node, where the broadcast message carries the identification information of the second relay node;
需要说明的是,此种情况指的是能够允许终端接入的中继节点会向终端发送广播消息(例如SIB、SIB1),该广播消息中携带中继节点自身的标识信息,终端接收到哪一个中继节点的广播消息,则确定可以通过哪一个中继节点进行接入,该中继节点即为第二中继节点。It should be noted that this situation means that the relay node that allows the terminal to access will send a broadcast message (such as SIB, SIB1) to the terminal. The broadcast message carries the identification information of the relay node itself. Which message is received by the terminal? The broadcast message of a relay node determines which relay node can be accessed through, and the relay node is the second relay node.
例如,如图3所示,IAB节点在广播消息(SIB)中增加其对应的IAB节点的标识(例如,IAB node ID),终端收到广播消息后,将RRC层的IAB节点的标识加入到NAS消息中进行注册。可选地,通过在PLMN身份信息列表(PLMN-IdentityInfoList)信息元素(information element)中增加IAB节点标识(iABNodeidentity)信息项来实现IAB节点的标识的通知。For example, as shown in Figure 3, the IAB node adds the identity of its corresponding IAB node (for example, IAB node ID) in the broadcast message (SIB). After receiving the broadcast message, the terminal adds the identity of the IAB node at the RRC layer to Register in NAS messages. Optionally, the notification of the identity of the IAB node is implemented by adding an IAB node identity (iABNodeidentity) information item to the PLMN identity information list (PLMN-IdentityInfoList) information element.
B12、根据允许所述终端接入的中继节点的标识信息以及中继节点的广播消息,确定所述第二中继节点的标识信息;B12. Determine the identification information of the second relay node according to the identification information of the relay node that allows the terminal to access and the broadcast message of the relay node;
需要说明的是,此种情况指的是终端侧存储有允许终端接入的中继节点的标识信息,同时允许终端接入的中继节点会向终端发送广播消息(例如SIB1),该广播消息中携带中继节点自身的标识信息,终端在接收到某一个中继节点的广播消息后,还需要判断该中继节点的是否位于允许终端接入的中继节点的标识信息中,若位于允许终端接入的中继节点的标识信息,则确定可以通过此中继节点进行接入,该中继节点即为第二中继节点。It should be noted that this situation refers to that the terminal side stores the identification information of the relay node that allows the terminal to access, and the relay node that allows the terminal to access will send a broadcast message (such as SIB1) to the terminal. The broadcast message carries the identification information of the relay node itself. After receiving the broadcast message of a certain relay node, the terminal also needs to determine whether the relay node is located in the identification information of the relay node that allows the terminal to access. If it is located in the allowed relay node If the terminal accesses the identification information of the relay node, it is determined that the terminal can access through this relay node, and the relay node is the second relay node.
也就是说,在上述B12的情况下,终端若收到其中某个IAB节点的广播,并且终端判断该IAB节点在自己的允许终端接入的中继节点的标识信息中,则将此IAB node ID增加在NAS消息中。That is to say, in the case of B12 above, if the terminal receives a broadcast from one of the IAB nodes, and the terminal determines that the IAB node is in the identification information of its own relay node that allows the terminal to access, then the IAB node The ID is added to the NAS message.
可选地,终端侧存储的允许终端接入的中继节点的标识信息可以通过上 述的注册接受消息或注册拒绝消息通知。Optionally, the identification information of the relay node that is allowed to be accessed by the terminal stored on the terminal side can be The above-mentioned registration acceptance message or registration rejection message notification.
B13、基于预配置的所述终端能够接入的中继节点的标识信息,获取第二中继节点的标识信息;B13. Acquire identification information of a second relay node based on pre-configured identification information of a relay node that the terminal can access;
需要说明的是,此种情况是为终端预配置能够接入的中继节点的标识,终端在接入时,选择一个中继节点在NAS消息中携带其标识信息即可。It should be noted that in this case, the terminal is pre-configured with the identification of the relay node that can be accessed. When the terminal accesses, it only needs to select a relay node and carry its identification information in the NAS message.
可选地,为了保证终端能够顺利接入所选的中继节点,通常终端在选择一个中继节点后还需要在接收到该中继节点发送的广播消息之后,才可以在NAS消息中携带该中继节点的标识信息。Optionally, in order to ensure that the terminal can successfully access the selected relay node, usually after the terminal selects a relay node, it needs to receive the broadcast message sent by the relay node before carrying the NAS message in the NAS message. Identification information of the relay node.
可选地,若终端侧存储有允许终端接入的存在中继节点的标识信息,在接收到第二中继节点的广播消息的情况下,判断是否能够通过所述第二中继节点接入;在确定能够通过所述第二中继节点接入的情况下,将所述第二中继节点的标识信息封装在NAS消息中;向第一中继节点发送所述NAS消息。Optionally, if the terminal side stores identification information of an existing relay node that allows the terminal to access, upon receiving a broadcast message from the second relay node, it determines whether it can be accessed through the second relay node. ; When it is determined that access through the second relay node is possible, encapsulate the identification information of the second relay node in a NAS message; send the NAS message to the first relay node.
可选地,在终端确定不能够通过所述第二中继节点接入的情况下,不执行接入操作。Optionally, if the terminal determines that it cannot be accessed through the second relay node, the access operation is not performed.
方式二、获取所述第二中继节点的标识信息,向所述核心网节点发送第一信息;Method 2: Obtain the identification information of the second relay node and send the first information to the core network node;
需要说明的是,在此种情况下,终端向第一中继节点发送的NAS消息中仅携带终端注册请求,第一中继节点需要在转发该NAS消息时,将第二中继节点的标识信息一同发送给核心网节点,因第一中继节点接收到的NAS消息是从第二中继节点发送的,则第一中继节点可以明确知道第二中继节点的标识信息。It should be noted that in this case, the NAS message sent by the terminal to the first relay node only carries the terminal registration request, and the first relay node needs to include the identifier of the second relay node when forwarding the NAS message. The information is sent to the core network node together. Because the NAS message received by the first relay node is sent from the second relay node, the first relay node can clearly know the identification information of the second relay node.

When the IAB anchor point receives a NAS message carrying a registration request from the IAB node, it sends the IAB node ID added to the registration request to the network.
注:NAS消息中是否携带IAB node ID取决于终端有没有收到携带IAB node ID的SIB1广播。如果没有携带,则网络会在本次注册完成时下发相关的IAB node ID信息给终端。Note: Whether the NAS message carries the IAB node ID depends on whether the terminal receives the SIB1 broadcast carrying the IAB node ID.
