技术领域technical field

本公开涉及通信技术领域，尤其涉及一种数据处理方法、设备、装置和存储介质。The present disclosure relates to the field of communication technologies, and in particular, to a data processing method, device, apparatus, and storage medium.

背景技术Background technique

为了扩展网络覆盖，一种解决方案就是引入中继(Relay)。对于一个具备中继功能的设备而言，其同时可以有两个角色：In order to expand the network coverage, a solution is to introduce a relay (Relay). For a device with relay function, it can have two roles at the same time:

作为中继设备，通过直接通信接口接收远端UE(User Equipment，用户设备)设备的数据，然后转发给网络设备或者其他UE；As a relay device, it receives the data of the remote UE (User Equipment, user equipment) device through the direct communication interface, and then forwards it to the network device or other UE;

作为普通UE，可以和其他UE进行直接通信接口的数据传输。As a common UE, it can perform data transmission on a direct communication interface with other UEs.

但是现有技术中，中继设备在接收到远端UE的数据后，无法识别出其接收到的数据是终止于该中继设备还是需要转发，即中继设备在通过直接接口接收到数据后，无法判断自己是应该作为中继将数据转发给网络设备或者其他UE，还是应该作为与远端UE直接通信的普通UE接收此数据。However, in the prior art, after receiving the data of the remote UE, the relay device cannot identify whether the received data is terminated by the relay device or needs to be forwarded, that is, after the relay device receives the data through the direct interface , it is impossible to judge whether it should forward the data to the network device or other UE as a relay, or should receive the data as a normal UE that communicates directly with the remote UE.

因此，如何让中继设备识别出不同类型的数据并进行正确处理成为亟需解决的问题。Therefore, how to make the relay device identify different types of data and process it correctly becomes an urgent problem to be solved.

其中，方法和装置是基于同一申请构思的，由于方法和装置解决问题的原理相似，因此装置和方法的实施可以相互参见，重复之处不再赘述。The method and the device are conceived based on the same application. Since the principles of the method and the device for solving the problem are similar, the implementation of the device and the method can be referred to each other, and repeated descriptions will not be repeated here.

传统的无线通信采用蜂窝网络通信方式，即终端和网络设备通过Uu接口进行上下行数据/控制信息的传输。图1是本公开实施例提供的一种蜂窝网络通信方式示意图；如图1所示，蜂窝网络通信是一种网络集中控制的通信方式。The traditional wireless communication adopts the cellular network communication mode, that is, the terminal and the network device transmit the uplink and downlink data/control information through the Uu interface. FIG. 1 is a schematic diagram of a cellular network communication mode provided by an embodiment of the present disclosure; as shown in FIG. 1 , the cellular network communication is a communication mode under centralized network control.

图2是本公开实施例提供的一种直接通信方式示意图；如图2所示，直接通信是指邻近的终端可以在近距离范围内通过直接通信链路(也称为Sidelink或者PC5)进行数据传输的方式。Sidelink链路对应的无线接口称为直接通信接口(也称为Sidelink接口或者PC5接口)；直接通信是一种端到端直接通信的方法，数据无需经由网络设备中转。FIG. 2 is a schematic diagram of a direct communication method provided by an embodiment of the present disclosure; as shown in FIG. 2 , direct communication means that adjacent terminals can communicate with data through a direct communication link (also called Sidelink or PC5) within a short range method of transmission. The wireless interface corresponding to the Sidelink link is called the direct communication interface (also called the Sidelink interface or the PC5 interface); direct communication is an end-to-end direct communication method, and data does not need to be transferred through network equipment.

为了扩展网络覆盖，一种解决方案就是引入中继(Relay)。Relay可以是一个具有中继功能的终端，也可以是任意具有中继功能的设备，本实施例对此不做限制。图3是本公开实施例提供的一种终端至网络设备数据转发示意图；如图3所示，对于远端UE至网络侧的中继UE-to-Network Relay，Relay和网络之间的接口使用Uu接口，和被中继UE，本公开各实施例中也称为远端UE，之间的接口使用直接通信接口。Relay和网络之间的链路对远端UE而言可以称为回程链路(Backhaul link,BH)。In order to expand the network coverage, a solution is to introduce a relay (Relay). The relay may be a terminal with a relay function, or may be any device with a relay function, which is not limited in this embodiment. FIG. 3 is a schematic diagram of data forwarding from a terminal to a network device provided by an embodiment of the present disclosure; as shown in FIG. 3 , for a UE-to-Network Relay from a remote UE to a relay on the network side, the interface between the Relay and the network uses The interface between the Uu interface and the relayed UE, also referred to as the remote UE in various embodiments of the present disclosure, uses a direct communication interface. The link between the relay and the network can be called a backhaul link (BH) for the remote UE.

对于远端UE至其他UE的中继UE-to-UE Relay，两个被中继UE可以通过中继UE进行数据传输。For the relay UE-to-UE Relay from the remote UE to other UEs, the two relayed UEs can transmit data through the relay UE.

另外，中继场景下的承载分为三类：In addition, the bearer in the relay scenario is divided into three categories:

远端UE在Uu接口回程链路的承载：即中继UE和网络设备之间用于承载远端UE数据的承载。The bearer of the remote UE on the backhaul link of the Uu interface: that is, the bearer used to bear the data of the remote UE between the relay UE and the network device.

无论是哪种类型的承载，承载和逻辑信道都是一一对应的，逻辑信道有对应的逻辑信道标识。Regardless of the type of bearer, the bearer and the logical channel are in one-to-one correspondence, and the logical channel has a corresponding logical channel identifier.

下面结合多个实施例对本公开进行详细介绍：The present disclosure will be described in detail below in conjunction with multiple embodiments:

图4是本公开实施例提供的一种数据处理方法流程示意图，如图4所示， 该方法应用于中继设备，包括如下步骤：FIG. 4 is a schematic flowchart of a data processing method provided by an embodiment of the present disclosure. As shown in FIG. 4 , the method is applied to a relay device and includes the following steps:

步骤400，通过直接通信接口接收远端用户终端UE发送的数据；Step 400, receiving data sent by a remote user terminal UE through a direct communication interface;

步骤410，根据特定标识信息，确定对所述数据的处理方式；其中，所述处理方式包括进行数据转发或终止于所述中继设备。Step 410: Determine a processing method for the data according to the specific identification information; wherein, the processing method includes forwarding data or terminating at the relay device.

具体地，中继通信(relay communication)，亦称“接力通信”，是一种延长通信距离的方法。利用无线方式传输信号时，发送端与接收端之间距离超过一定距离时，信号衰减很快，无法保证通信质量。因此可以在发送端与接收端之间设置至少一个中继设备，中继设备将前站送来的信号转发到下一站，可延长通信距离并保持较好的通信质量。Specifically, relay communication, also known as "relay communication", is a method of extending the communication distance. When the signal is transmitted wirelessly, when the distance between the sender and the receiver exceeds a certain distance, the signal attenuates rapidly, and the communication quality cannot be guaranteed. Therefore, at least one relay device can be set between the sending end and the receiving end, and the relay device forwards the signal from the previous station to the next station, which can extend the communication distance and maintain better communication quality.

具体地，中继设备可以通过直接通信接口接收远端UE发送的数据，也可称其为直接通信接口数据；其中，该数据可能是远端UE在与中继设备进行直接通信时发送给中继设备的，也可能是远端UE希望通过中继设备将数据转发给其他UE或网络设备的，因此，中继设备需要对接收到的数据进行区分，确定对接收到的每一数据的处理方式，比如将数据进行转发至网络设备或其他UE，或将数据终止于中继设备。。Specifically, the relay device can receive data sent by the remote UE through the direct communication interface, which may also be referred to as direct communication interface data; wherein, the data may be sent by the remote UE to the intermediate UE during direct communication with the relay device. The relay device may also be the remote UE wishing to forward data to other UEs or network devices through the relay device. Therefore, the relay device needs to distinguish the received data and determine the processing of each received data. way, such as forwarding the data to the network device or other UEs, or terminating the data in the relay device. .

具体地，为了可以使中继设备正确地对接收到的数据进行处理，可以将特定标识信息与数据对应，中继设备接收到数据后，可以基于特定识别信息确定对该数据的处理方式，比如数据转发或者终止于中继设备。Specifically, in order to enable the relay device to correctly process the received data, specific identification information can be corresponding to the data. After the relay device receives the data, it can determine the processing method of the data based on the specific identification information, such as Data is forwarded or terminated at the relay device.

以中继设备为中继UE为例，可以称其为UE2，可以称远端UE为UE1，当UE2从直接通信接口接收到UE1发送的数据后，可以基于数据对应的特定识别信息确定对该数据的处理方式，比如数据转发或者终止于UE2。Taking the relay device as the relay UE as an example, it can be called UE2, and the remote UE can be called UE1. After UE2 receives the data sent by UE1 from the direct communication interface, it can determine the specific identification information corresponding to the data. Data processing method, such as data forwarding or termination at UE2.

具体地，本实施例中，中继设备确定要对数据进行转发后，可以通过接收其他指令或信息，来确定数据需要转发的通信对端是网络设备还是其他UE，进一步还可确定转发给哪一UE，本实施例对中继设备确定处理方式后的操作或步骤不做限制，任意可以实现相应数据处理的方式或各种中继设备本身具备的可以实现相应数据处理的功能均适用于本实施例。Specifically, in this embodiment, after the relay device determines that the data needs to be forwarded, it can determine whether the communication peer to which the data needs to be forwarded is a network device or another UE by receiving other instructions or information, and can further determine to which to forward the data. A UE. This embodiment does not limit the operations or steps after the relay device determines the processing mode. Any mode that can implement corresponding data processing or the functions of various relay devices that can implement corresponding data processing are applicable to this embodiment. Example.

具体地，特定标识信息可以是直接通信接口承载或者逻辑信道标识，即可以通过特定的直接通信接口承载或者逻辑信道传输需要中继设备转发的数据，中继设备在接收数据时，会基于直接通信接口承载或者逻辑信道标识确定通过特定的直接通信接口承载或者逻辑信道传输的数据是需要转发的数据，相应地，基于直接通信接口承载或者逻辑信道标识确定未通过特定的直接通信接口承载或者逻辑信道传输的数据可以终止于中继设备，即中继设备可以接收该数据并递交到自身高层，比如业务层。Specifically, the specific identification information may be the direct communication interface bearer or the logical channel identification, that is, the data that needs to be forwarded by the relay device may be transmitted through the specific direct communication interface bearer or logical channel. The interface bearer or logical channel identifier determines that the data transmitted through the specific direct communication interface or the logical channel is the data that needs to be forwarded. The transmitted data can be terminated at the relay device, that is, the relay device can receive the data and deliver it to its own higher layer, such as the service layer.

具体地，特定标识信息可以是直接通信接口特定协议层的PDU头中携带的标识或直接通信接口控制信息SCI中携带的标识；具体地，直接通信接口特定协议层的PDU头中携带的标识或直接通信接口控制信息SCI中携带的标识可以是指示信息，用于指示中继设备对该数据进行转发或者终止于中继设备。Specifically, the specific identification information may be the identification carried in the PDU header of the specific protocol layer of the direct communication interface or the identification carried in the direct communication interface control information SCI; specifically, the identification carried in the PDU header of the specific protocol layer of the direct communication interface or The identifier carried in the direct communication interface control information SCI may be indication information, which is used to instruct the relay device to forward the data or to terminate the data at the relay device.

具体地，若所述特定标识为直接通信接口连接标识，中继设备可以首先获取直接通信接口连接标识与处理方式的对应关系，具体地，中继设备可以 在接收远端UE发送的直接通信接口连接建立请求消息时获取。Specifically, if the specific identifier is the direct communication interface connection identifier, the relay device may first obtain the correspondence between the direct communication interface connection identifier and the processing method.
