Description

传输控制方法、装置及存储介质Transmission control method, device and storage medium 技术领域Technical field
本发明涉及无线通信技术，尤指一种传输控制方法、装置及存储介质。The present invention relates to a wireless communication technology, and more particularly to a transmission control method, apparatus, and storage medium.
背景技术Background technique
第五代(5 thGeneration，简称5G)网络架构具有革新性和组网的灵活性，在5G网络中无线接入网侧的基带处理单元(Building Base band Unit，简称BBU)被分离为集中式处理单元(Centralized Unit，简称CU)和分布式处理单元(Distributed Unit，简称DU)两个功能实体。通过集中式CU来控制多个DU，可以实现云架构的基带集中处理和针对用户的远端分布式提供服务。在CU-DU分离的网络架构中，时延不敏感的网络功能放在CU中，时延敏感的网络功能放在DU中，CU与DU之间通过理想/或非理想前传(fronthaul)进行传输和连接，实现多点协作化功能，并可以支持分离或一体化站点的灵活组网。 Fifth Generation (5 th Generation, abbreviated 5G) network architecture with the flexibility and range of the network, in a radio access network 5G network side, the baseband processing unit (Building Base band Unit, abbreviated BBU) is separated into a centralized Two functional entities: a Centralized Unit (CU) and a Distributed Unit (DU). By controlling multiple DUs through a centralized CU, centralized processing of the baseband of the cloud architecture and remote distributed provisioning for users can be implemented. In the CU-DU separate network architecture, the delay-insensitive network function is placed in the CU, and the delay-sensitive network function is placed in the DU. The CU and the DU are transmitted through the ideal/or non-ideal frontal (fronthaul). And connectivity for multi-point collaboration and support for flexible networking of separate or integrated sites.
如图1所示，在CU-DU的分离方案中，有方案2(OPTION2)和方案3(OPTION3)两种方案。其中在OPTION2中，分组数据汇聚协议(Packet Data Convergence Protocol，简称PDCP)位于CU，无线链路层控制协议(Radio Link Control，简称RLC)层及RLC层以下层位于DU，CU和DU之间数据面传输使用PDCP PDU(Protocol Data Unit，协议数据单元)数据包进行传输。在OPTION3中，RLC的非时延敏感功能包括自动重传请求(Automatic Repeat Request，简称ARQ)等功能位于CU，RLC的另一部分对时延敏感的包括实时分段等功能位于DU，CU和DU之间数据面传输使用RLC PDU。无论是OPTION2还是OPTION3，在下行数据传输上，CU需要将传递给用户设备(User Equipment，简称UE)的下行数据(在 OPTION2中是PDCP PDU，在OPTION3中是RLC PDU)发送给DU，由实际的DU来发送给UE。由于DU实际传输能力受到空口资源调度和信道质量等各方面因素的影响，CU和DU之间存在用户面的流控接口，DU需要向CU申请数据用于一段时间内的发送。但由于CU和DU是分离的，DU的数据传输过程中，CU并无法准确的判断DU对这些缓存数据的传输情况。很可能DU数据传输发生问题，而CU无法及时获知，导致数据时延增大，甚至丢包。如果仅仅是依靠物理层的链路检测来监测DU上的传输链路是否失败，可能在物理层上报链路失效前，DU就已经发生了数据包持续传输错误和时延增大。As shown in FIG. 1, in the separation scheme of the CU-DU, there are two schemes of scheme 2 (OPTION2) and scheme 3 (OPTION3). In the OPTION2, the Packet Data Convergence Protocol (PDCP) is located in the CU, and the Radio Link Control (RLC) layer and the RLC layer are located between the DU, the CU and the DU. The polygon transmission uses a PDCP PDU (Protocol Data Unit) packet for transmission. In OPTION3, the non-delay-sensitive functions of the RLC include automatic repeat request (ARQ) and other functions located in the CU. Another part of the RLC is sensitive to delay, including real-time segmentation. The functions are located in DU, CU and DU. The data plane transmission uses RLC PDUs. On the downlink data transmission, the CU needs to send the downlink data (PDCP PDU in OPTION2 and RLC PDU in OPTION3) to the DU, which is actually used by the user equipment (User Equipment, UE for short). The DU is sent to the UE. Because the actual transmission capacity of the DU is affected by various factors such as air interface resource scheduling and channel quality, there is a flow control interface of the user plane between the CU and the DU. The DU needs to apply for data to the CU for transmission within a period of time. However, since the CU and the DU are separated, during the data transmission process of the DU, the CU cannot accurately determine the transmission of the DU to the cached data. It is very likely that there is a problem with the DU data transmission, and the CU cannot be informed in time, resulting in an increase in data delay and even packet loss. If only the link detection of the physical layer is used to monitor whether the transmission link on the DU fails, the DU may have a continuous transmission error and an increase in delay before the physical layer reports that the link fails.
相关技术中，CU-DU分离的架构下，CU并无法及时的获知DU中下行缓存数据的传输情况，从而出现数据时延增大，甚至丢包的问题。In the related art, under the CU-DU separation architecture, the CU cannot know the transmission condition of the downlink buffer data in the DU in time, and thus the data delay increases or even the packet loss problem occurs.
发明内容Summary of the invention
有鉴于此，本发明实施例期望提供一种传输控制方法、装置及存储介质，使得CU能及时获知DU中下行缓存数据的传输质量，以便采取相应措施，减少数据传输时延和丢包率。In view of this, the embodiment of the present invention is to provide a transmission control method, device, and storage medium, so that the CU can know the transmission quality of the downlink buffer data in the DU in time, so as to take corresponding measures to reduce the data transmission delay and the packet loss rate.
