技术领域technical field

本申请属于通信技术领域，具体涉及一种数据路由方法及装置。The present application belongs to the field of communication technologies, and in particular relates to a data routing method and device.

背景技术Background technique

基于当前回传适配协议(Backhaul Adaptation Protocol，BAP)重路由，由于仅在无线链路失败(Radio Link Failure，RLF)出现的情况下，重新确定下一跳自回传(Integrated Access and Backhaul，IAB)节点，替代路径不能预先配置，易造成局部阻塞和不可控。另外，集中单元(Centralized Unit，CU)可以配置某一路径的备选路径或某一宿主(donor)分布单元(Distributed Unit，DU)的备选donor DU，或某一接入IAB节点的备选接入IAB节点，中间IAB节点可以基于局部负荷情况，为转发的BAP协议数据单元(Protocol Data Unit，PDU)重新选择使用备选路径(适用上下行)，备选donor DU(适用下行)或备选接入IAB节点(适用下行)。备选路径和备选目标节点配置后，中间IAB节点根据局部情况，改写BAP PDU的BAP header中的路径(path)ID和/或BAP地址(address)，之后下一中间IAB节点需基于改写后的BAP路由(routing)ID继续转发数据；也就是说，现有技术中只能根据单一的备选BAP地址或单一的备选路径进行路由，导致后续IAB节点为转发的BAP PDU无法重新选择更好的BAP路由。Based on the current backhaul adaptation protocol (Backhaul Adaptation Protocol, BAP) rerouting, because only in the case of a radio link failure (Radio Link Failure, RLF), the next hop self-backhaul (Integrated Access and Backhaul) is re-determined, IAB) node, the alternative path cannot be preconfigured, which is easy to cause partial blocking and uncontrollable. In addition, the centralized unit (Centralized Unit, CU) can configure an alternative path of a certain path or an alternative donor DU of a certain donor (donor) distributed unit (Distributed Unit, DU), or an alternative access to the IAB node. Accessing the IAB node, the intermediate IAB node can re-select an alternative path (for uplink and downlink) for the forwarded BAP protocol data unit (Protocol Data Unit, PDU) based on the local load situation, alternative donor DU (for downlink) or standby Select to access the IAB node (for downlink). After the alternate path and the alternate target node are configured, the intermediate IAB node rewrites the path ID and/or BAP address (address) in the BAP header of the BAP PDU according to the local situation, and then the next intermediate IAB node needs to be based on the rewritten path. The BAP routing ID continues to forward data; that is, in the prior art, routing can only be performed according to a single alternative BAP address or a single alternative path, resulting in the subsequent IAB node being unable to reselect the forwarded BAP PDU. Good BAP routing.

首先，对本申请中的相关术语进行解释说明。First, related terms in this application are explained.

一、IAB网络简介1. Introduction to IAB Network

图2是现有技术中IAB***的示意图，如图2所示，一个IAB节点包括分布单元(Distributed Unit，DU)功能部分和移动终端(Mobile Termination，MT)功能部分。依靠MT，一个接入节点(即IAB node)可以找到一个上游接入点(parent IAB node或者IAB-donor-DU)，并跟上游接入点的DU建立无线连接，该无线连接被称为回传链路(backhaul link)。在一个IAB节点建立完整的回传链路后，该IAB节点打开其DU功能，DU会提供小区服务，即DU可以为用户设备(User Equipment，UE)提供接入服务。一个自回传回路包括一个donor IAB节点(或者称为IAB donor，由IAB-donor-CU和IAB-donor-DU组成)，donor IAB节点有直接相连的有线传输网。FIG. 2 is a schematic diagram of an IAB system in the prior art. As shown in FIG. 2 , an IAB node includes a distributed unit (Distributed Unit, DU) functional part and a mobile terminal (Mobile Termination, MT) functional part. Relying on MT, an access node (ie IAB node) can find an upstream access point (parent IAB node or IAB-donor-DU), and establish a wireless connection with the DU of the upstream access point. backhaul link. After an IAB node establishes a complete backhaul link, the IAB node enables its DU function, and the DU provides cell services, that is, the DU can provide access services for user equipment (User Equipment, UE). A self-backhaul loop includes a donor IAB node (or called IAB donor, which is composed of IAB-donor-CU and IAB-donor-DU), and the donor IAB node has a directly connected wired transmission network.

图3是一个IAB***的集中/分布单元(Centralized Unit-Distributed Unit，CU-DU)结构图。在一个自回传回路中，所有的IAB节点的DU都连接到一个CU节点，由这一个节点通过F1-AP协议进行对DU进行配置。CU通过无线资源控制(Radio Resource Control，RRC)协议，对MT进行配置。IAB-donor-DU节点没有MT功能部分。FIG. 3 is a structural diagram of a centralized/distributed unit (Centralized Unit-Distributed Unit, CU-DU) of an IAB system. In a self-backhaul loop, the DUs of all IAB nodes are connected to a CU node, which configures the DUs through the F1-AP protocol. The CU configures the MT through a radio resource control (Radio Resource Control, RRC) protocol. IAB-donor-DU nodes have no MT functional part.

二、IAB网络的BAP协议简介：2. Introduction to the BAP protocol of the IAB network:

回传适配协议(Backhaul Adaptation Protocol，BAP)是用于IAB网络IAB节点之间的路由协议，即把上行数据从接入IAB节点路由到donor DU，把下行数据从donor DU路由到接入IAB节点。BAP层位于分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层和无线链路层控制协议(Radio Link Control，RLC)层之间。对于上行数据，Donor DU收到来自CU的下行PDCP PDU后，根据目的IP地址与BAP路由的映射关系，确定目的接入IAB节点的BAP地址和到目的接入IAB节点的路径，生成BAP header，加到PDCP PDU之前，生成BAP PDU，该BAP header指引沿途各IAB节点将BAP PDU发送到目的接入IAB节点；对于上行数据，接入IAB节点在收到来自UE的上行PDCP PDU后，根据其对应的GTP-U TEID与BAP路由的映射关系生成BAP header，加到PDCP PDU之前，生成BAP PDU，该BAP header指引沿途给IAB节点将BAP PDU发送到目的donor DU节点。BAP header的格式如图4所示，BAP routing ID包括10bit的BAP address和10bit的path ID，其中BAP address是目的IAB节点的BAP地址，path ID指示到达目的IAB节点的路径，即途径的各IAB节点。Backhaul Adaptation Protocol (BAP) is a routing protocol used between IAB nodes in the IAB network, that is, the uplink data is routed from the access IAB node to the donor DU, and the downlink data is routed from the donor DU to the access IAB. node. The BAP layer is located between the Packet Data Convergence Protocol (PDCP) layer and the Radio Link Control Protocol (Radio Link Control, RLC) layer. For uplink data, after receiving the downlink PDCP PDU from the CU, the Donor DU determines the BAP address of the destination access IAB node and the path to the destination access IAB node according to the mapping relationship between the destination IP address and the BAP route, and generates a BAP header. Before being added to the PDCP PDU, a BAP PDU is generated, and the BAP header guides each IAB node along the way to send the BAP PDU to the destination access IAB node; for uplink data, the access IAB node receives the uplink PDCP PDU from the UE, according to its The mapping relationship between the corresponding GTP-U TEID and the BAP route generates a BAP header, which is added before the PDCP PDU to generate a BAP PDU. The BAP header guides the IAB node along the way to send the BAP PDU to the destination donor DU node. The format of the BAP header is shown in Figure 4. The BAP routing ID includes a 10-bit BAP address and a 10-bit path ID, where the BAP address is the BAP address of the destination IAB node, and the path ID indicates the path to the destination IAB node, that is, each IAB of the route. node.

After any optional donor DU receives the BAP data PDU, it can send the BAP The data carried by the PDU is forwarded to the donor CU;

2)给接入IAB节点配置BAP path组ID包含多个可选路径，每一路径都可以到达一个可选donor DU节点；2) Configure the BAP path group ID for the access IAB node to include multiple optional paths, and each path can reach an optional donor DU node;

此外，CU可以配置一个donor DU节点基于BAP地址组ID和/或BAP路径组ID产生下行BAP PDU，具体包括以下两种情况下：In addition, the CU can configure a donor DU node to generate downlink BAP PDUs based on the BAP address group ID and/or the BAP path group ID, including the following two cases:

2)给donor DU配置BAP path组ID包含多个可选路径，每一路径都可以到达一个可选接入IAB节点。2) Configure the BAP path group ID for the donor DU to include multiple optional paths, and each path can reach an optional access IAB node.

可见，对于无论是上行还是下行BAP PDU，均是可以事先配置BAP地址组ID和/或BAP路径组ID，以便后续上行或下行数据路由中可以通过该BAP地址组ID和/或BAP路径组ID进行重路由，即每一个IAB节点均是可以根据实际情况确定是否要进行重路由，而且每一个IAB节点也能确定当前BAP PDU是经过重路由后的BAP PDU还是首选的BAP PDU。It can be seen that for either an uplink or a downlink BAP PDU, the BAP address group ID and/or the BAP path group ID can be configured in advance, so that the BAP address group ID and/or the BAP path group ID can be passed in the subsequent uplink or downlink data routing. Perform rerouting, that is, each IAB node can determine whether to perform rerouting according to the actual situation, and each IAB node can also determine whether the current BAP PDU is the rerouted BAP PDU or the preferred BAP PDU.

对于本申请是实施例中步骤504涉及到的基于路由信息对BAP PDU进行重路由的方式，进一步可以包括：基于路由信息对BAP PDU执行第一操作，其中，第一操作包括以下之一：转发、丢弃、接收。For the present application, the method for rerouting the BAP PDU based on the routing information involved in step 504 in the embodiment may further include: performing a first operation on the BAP PDU based on the routing information, wherein the first operation includes one of the following: forwarding , discard, receive.

对此，如果当前IAB节点不是目的IAB节点，则需要将BAP PDU转发到下一IAB节点，如果当前IAB节点为目的IAB节点，例如，donor CU，则当前IAB节点则接收该BAP PDU进行后续的处理。如果当前IAB节点接收到BAP PDU之后，确定该BAP PDU与当前IAB节点无关，则当前IAB节点丢弃该BAP PDU。In this regard, if the current IAB node is not the destination IAB node, the BAP PDU needs to be forwarded to the next IAB node. If the current IAB node is the destination IAB node, for example, donor CU, the current IAB node will receive the BAP PDU for subsequent deal with. If the current IAB node determines that the BAP PDU is irrelevant to the current IAB node after receiving the BAP PDU, the current IAB node discards the BAP PDU.

在本申请实施例的可选实施方式中，对于本申请实施例中步骤504涉及到的基于路由信息对BAP PDU进行重路由的方式，进一步可以包括：In an optional implementation manner of the embodiment of the present application, the method for rerouting the BAP PDU based on the routing information involved in step 504 in the embodiment of the present application may further include:

步骤504-11，在路由信息中携带有目标路由信息的情况下，基于目标路由信息确定下一转发的第一IAB节点，并向第一IAB节点转发BAP PDU；其中，目标路由信息包括以下至少一项的信息：主选BAP地址、主选BAP路径；Step 504-11, in the case that the target routing information is carried in the routing information, determine the first IAB node to be forwarded next based on the target routing information, and forward the BAP PDU to the first IAB node; wherein, the target routing information includes at least the following: Information of one item: main BAP address, main BAP path;

步骤504-12，在路由信息中未携带有目标路由信息的情况下，从路由信息中选择一个目的IAB节点的BAP地址或一条BAP路径，以确定下一转发的第二IAB节点，并向第二IAB节点转发BAP PDU。Step 504-12, in the case that the routing information does not carry the target routing information, select a BAP address or a BAP path of a destination IAB node from the routing information to determine the second IAB node to be forwarded next, and send the information to the first IAB node. Two IAB nodes forward BAP PDUs.

进一步地，在基于目标路由信息确定下一转发的第一IAB节点之前，本申请实施例的方法还包括：Further, before determining the first IAB node to be forwarded next based on the target routing information, the method of the embodiment of the present application further includes:

步骤11，在主选BAP路径未出现拥塞或中断的情况下，基于主选BAP路径确定下一转发的第一IAB节点； Step 11, in the case that the main BAP path is not congested or interrupted, the first IAB node to be forwarded next is determined based on the main BAP path;

步骤12，在主选BAP路径出现拥塞或中断的情况下，从路由信息中选择备选BAP路径以确定下一转发的第二IAB节点。 Step 12, in the case of congestion or interruption of the primary BAP path, select an alternate BAP path from the routing information to determine the next forwarding second IAB node.

基于上述在具体应用场景中，对于上下行BAP PDU的配置，在具体进行重路由时可以是：当基于BAP地址组ID和/或BAP path组ID的BAP PDU产生后，不论是始发IAB节点，还是中间IAB节点，如果BAP PDU携带的BAP地址组ID和/或BAP path组ID配置有主选BAP地址和/或主选BAP path，则按优先选择主选BAP地址和/或主选BAP path确定BAP PDU的下一转发IAB节点；否则接入IAB节点可以自主选择一个可选BAP地址和可以到达该BAP地址的可选路径，从而确定下一转发点。当主选路径出现拥塞或中断时，可以选择其它备选路径；当主选目的接收IAB节点不可达时，可以选择其它备选接收IAB节点；然后据此确定下一转发节点。Based on the above in the specific application scenario, for the configuration of the uplink and downlink BAP PDUs, the specific rerouting can be: when the BAP PDU based on the BAP address group ID and/or the BAP path group ID is generated, whether it is the originating IAB node , or an intermediate IAB node, if the BAP address group ID and/or BAP path group ID carried in the BAP PDU is configured with the primary BAP address and/or the primary BAP path, the primary BAP address and/or the primary BAP path are selected according to preference path determines the next forwarding IAB node of the BAP PDU; otherwise, the access IAB node can independently select an optional BAP address and an optional path that can reach the BAP address, thereby determining the next forwarding point. When the main selected path is congested or interrupted, other alternative paths can be selected; when the main selected destination receiving IAB node is unreachable, other alternative receiving IAB nodes can be selected; and then the next forwarding node is determined accordingly.

也就是说，在具体应用场景中，当一个中间IAB节点收到一个legacy BAP PDU(即携带BAP地址和BAP path的BAP PDU)后，在满足预配置条件的情况下，需要对数据进行重新确定路由时，可以BAP地址组ID和/或BAP路径组ID替换BAP PDU中的BAP地址或BAP path，该BAP地址组ID中的任一目的IAB节点均能确保数据转发到最终节点(即目标UE或CU)。That is to say, in a specific application scenario, when an intermediate IAB node receives a legacy BAP PDU (that is, a BAP PDU carrying a BAP address and a BAP path), the data needs to be re-determined when the pre-configured conditions are met. When routing, the BAP address or BAP path in the BAP PDU can be replaced by the BAP address group ID and/or the BAP path group ID. Any destination IAB node in the BAP address group ID can ensure that the data is forwarded to the final node (that is, the target UE). or CU).

如图6a所示，自donor DU1到IAB1的下行重路由示例，因为首选BAP路由BAP routing ID1出现拥塞，donor DU1选择了备选路径BAP routing ID2并改写BAP PDU的BAP header,中间节点IAB7必须遵循BAP routing ID2的路线，但是实际上BAP routing ID3的负荷最低，IAB7却不能根据实际负荷情况选择BAP routing ID3。如图6b所示，为上行重自IAB1到CU的重路由的情形，由于原首选路径自IAB1到donor DU1的BAP Routing ID1’出现拥塞，基于IAB感受到的负荷情况，IAB3为自IAB1收到的BAP PDU重选了BAP routing ID3’，并将BAP PDU中的BAP routing ID1改写为BAP routing ID3’，IAB7收到改写BAP header后的BAP PDU后，基于其中携带的BAP routing ID3’将该BAP PDU发送给donor DU2，但是实际上BAP routing ID2路径才是最好的，但是IAB7却不能根据实际负荷情况自主选择BAP routing ID 2’。可见，本申请实施例相比于只能通过单一备选BAP地址或单一备选路径的方式，对于中间IAB节点而言，可以根据一个BAP PDU携带的BAP地址组ID和路径组ID灵活确定其转发的下一个IAB节点和终点IAB节点。As shown in Figure 6a, an example of downlink rerouting from donor DU1 to IAB1, because the preferred BAP route BAP routing ID1 is congested, donor DU1 selects the alternative path BAP routing ID2 and rewrites the BAP header of the BAP PDU, and the intermediate node IAB7 must follow the The route of BAP routing ID2, but in fact the load of BAP routing ID3 is the lowest, but IAB7 cannot select BAP routing ID3 according to the actual load situation. As shown in Figure 6b, for the rerouting of the uplink from IAB1 to CU, because the BAP Routing ID1' of the original preferred path from IAB1 to donor DU1 is congested, based on the load situation felt by IAB, IAB3 is received from IAB1. The BAP PDU re-selects BAP routing ID3', and rewrites BAP routing ID1 in the BAP PDU to BAP routing ID3'. After IAB7 receives the BAP PDU with the rewritten BAP header, based on the BAP routing ID3' carried in it, the BAP routing ID3' The PDU is sent to the donor DU2, but in fact the BAP routing ID2 path is the best, but the IAB7 cannot independently select the BAP routing ID 2' according to the actual load situation. It can be seen that, compared with the method that can only use a single candidate BAP address or a single candidate path in the embodiment of the present application, for the intermediate IAB node, the BAP address group ID and path group ID carried by a BAP PDU can be flexibly determined. The next IAB node and destination IAB node for forwarding.

在本申请实施例的可选实施方式中，对于本申请中涉及到的基于路由信息接收BAP PDU的方式，进一步可以包括：In an optional implementation of the embodiment of this application, the method of receiving BAP PDUs based on routing information involved in this application may further include:

步骤11，在满足以下之一的情况下，去掉BAP PDU的BAP header,并把去掉BAP header的BAP PDU提交上层协议层处理： Step 11, under one of the following conditions, remove the BAP header of the BAP PDU, and submit the BAP PDU with the BAP header removed to the upper protocol layer for processing:

1)当BAP PDU携带的BAP地址组ID与IAB节点所属的BAP地址组ID相同；1) When the BAP address group ID carried by the BAP PDU is the same as the BAP address group ID to which the IAB node belongs;

2)当BAP PDU携带的BAP地址组ID指示的BAP地址组中有一个BAP地址与IAB节点的BAP地址相同。2) When there is a BAP address in the BAP address group indicated by the BAP address group ID carried by the BAP PDU and the BAP address of the IAB node is the same.

在本申请实施例的可选实施方式中，对于本申请中涉及到的基于路由信息转发BAP PDU的方式，进一步可以包括：In an optional implementation of the embodiment of the present application, the method of forwarding the BAP PDU based on routing information involved in the present application may further include:

步骤21，当IAB节点可以找到路径到BAP地址组ID指示的任一目的IAB地址时，对BAP PDU进行转发。Step 21, when the IAB node can find a path to any destination IAB address indicated by the BAP address group ID, it forwards the BAP PDU.

在本申请实施例的可选实施方式中，在满足以下之一的情况下，基于路由信息丢弃BAP PDU：In an optional implementation of this embodiment of the present application, the BAP PDU is discarded based on routing information under one of the following conditions:

1)BAP PDU携带的BAP地址组ID与IAB节点所属的BAP地址组ID不相同；1) The BAP address group ID carried by the BAP PDU is different from the BAP address group ID to which the IAB node belongs;

2)未找到一条到任一目的IAB地址的路径。2) No path to any destination IAB address was found.

在本申请实施例的可选实施方式中，本申请实施例中的BAP地址组ID和BAP地址的格式相同；路径组ID的格式和BAP路径格式相同，即目的IAB节点的BAP地址和BAP路径的BAP header格式与BAP data PDU的BAP header格式一致。In an optional implementation of the embodiment of the present application, the BAP address group ID and the BAP address in the embodiment of the present application are in the same format; the path group ID is in the same format as the BAP path format, that is, the BAP address of the destination IAB node and the BAP path The BAP header format of the BAP data PDU is consistent with the BAP header format of the BAP data PDU.

对此，在具体应用场景中，CU可以将BAP地址组ID和该BAP地址组中包含的各BAP地址(和/或path组ID和该path组包含的各BAP path ID) 通过F1AP或者RRC消息通知各相关IAB节点。图7显示格式中，BAP地址组ID/BAP path组ID使用了与BAP data PDU相同的BAP header格式，即BAP地址组ID占据BAP地址域10bit，BAP path组ID占据BAP path ID域10bit，完全与现有BAP header格式兼容。由于BAP地址组ID(或path组ID)共用BAP地址指示域(或path ID指示域)，CU需要预留BAP地址值空间(或path值空间)用于BAP地址组ID(或path组ID)分配。In this regard, in a specific application scenario, the CU can pass the BAP address group ID and each BAP address contained in the BAP address group (and/or the path group ID and each BAP path ID contained in the path group) through F1AP or RRC message Notify each relevant IAB node. In the display format shown in Figure 7, the BAP address group ID/BAP path group ID uses the same BAP header format as the BAP data PDU, that is, the BAP address group ID occupies 10 bits in the BAP address field, and the BAP path group ID occupies 10 bits in the BAP path ID field. Compatible with existing BAP header formats. Since the BAP address group ID (or path group ID) shares the BAP address indication field (or path ID indication field), the CU needs to reserve the BAP address value space (or path value space) for the BAP address group ID (or path group ID) distribute.

图7显示格式显示了3种格式：Figure 7 Display Format shows 3 formats:

a)显示了携带BAP地址和BAP path组ID的格式，适用于指示到同一目标IAB节点的多条可选路径的情形；a) shows the format of carrying BAP address and BAP path group ID, which is suitable for the situation of indicating multiple optional paths to the same target IAB node;

b)显示了携带BAP地址组ID和BAP path的格式，适用于指示多个可选目的IAB节点和到其中一个目的接收IAB节点的主选路径；b) shows the format of carrying the BAP address group ID and BAP path, which is suitable for indicating multiple optional destination IAB nodes and the main selection path to one of the destination receiving IAB nodes;

c)显示了同时携带BAP地址组ID和BAP path组ID的格式，适用于指示多个可选目的IAB节点和到其中一个或多个目的接收IAB节点的多条可选路径的情形；c) shows the format of carrying the BAP address group ID and the BAP path group ID at the same time, which is applicable to the situation of indicating multiple optional destination IAB nodes and multiple optional paths to one or more of the destination receiving IAB nodes;

图8重定义了原BAP header格式中的R-bit来指示BAP PDU携带的是BAP地址组ID(和/或path组ID)，即用于指示BAP header的格式，使用这一格式无需为BAP地址组ID(或path组ID)预留BAP地址值空间(或path值空间)用于BAP地址组ID(或path组ID)分配。图8中的d，e和f分别对应图7的a，b和c。Figure 8 redefines the R-bit in the original BAP header format to indicate that the BAP PDU carries the BAP address group ID (and/or path group ID), that is, the format used to indicate the BAP header, and it is not necessary to use this format for BAP The address group ID (or path group ID) reserves the BAP address value space (or path value space) for BAP address group ID (or path group ID) allocation. d, e and f in Fig. 8 correspond to a, b and c in Fig. 7, respectively.
