技术领域technical field

本申请实施例涉及通信技术领域，尤其涉及一种数据的传输方法，通信装置和通信***。The embodiments of the present application relate to the field of communication technologies, and in particular, to a data transmission method, a communication device, and a communication system.

背景技术Background technique

随着通信技术的发展，对于终端设备与其他设备(如终端设备或网络设备)之间的可靠性要求更高。而目前的通信架构往往不能满足一些通信场景中对于可靠性的要求。例如，在与工厂(to business，to B)相关业务的通信场景下，移动控制(Motion Control，MC)业务对于终端设备到其他设备的可靠性要求为999,999，即一年中允许通信服务终端的故障总时长不超过30秒。而基于目前的通信架构进行该MC业务时，网络设备(如基站)的可靠性仅为999到9999，由此也导致整个通信链路的可靠性远不能满足MC业务等to B业务对于可靠性的要求。With the development of communication technology, higher reliability is required between terminal equipment and other equipment (such as terminal equipment or network equipment). However, the current communication architecture often cannot meet the reliability requirements in some communication scenarios. For example, in the communication scenario of the business related to the factory (to business, to B), the reliability requirement of the mobile control (Motion Control, MC) business for the terminal equipment to other equipment is 999,999, that is, the number of allowed communication service terminals in one year is 999,999. The total duration of the fault does not exceed 30 seconds. However, when the MC service is performed based on the current communication architecture, the reliability of network equipment (such as base stations) is only 999 to 9999, which also results in that the reliability of the entire communication link is far from meeting the reliability requirements of to B services such as MC services. requirements.

发明内容SUMMARY OF THE INVENTION

本申请实施例提供一种数据的传输方法，通信装置和通信***，解决了目前通信链路无法满足业务对可靠性的需求的问题。The embodiments of the present application provide a data transmission method, a communication device and a communication system, which solve the problem that the current communication link cannot meet the reliability requirements of the service.

为达到上述目的，本申请实施例采用如下技术方案：In order to achieve the above purpose, the embodiment of the present application adopts the following technical solutions:

第一方面，提供一种数据的传输方法，该方法包括：第一接入网设备接收来自第二接入网设备的第一信息，第一信息包括第一终端设备的第一连接参数，第二接入网设备根据第一连接参数与第一终端设备进行通信，第一接入网设备和第二接入网设备具有相同的小区配置。第一接入网设备确定第二接入网设备出现故障。第一接入网设备根据第一连接参数与第一终端设备进行通信。基于该方案，提供了一种辅接入网设备(如第一接入网设备)与主接入网设备(如第二接入网设备)的工作机制。其中，第一接入网设备可以为辅接入网设备，第二接入网设备可以主接入网设备。能够使得在一个接入网设备(如主接入网设备)出现故障时，另一个接入网设备(如辅接入网设备)能够快速地接管主接入网设备的通信工作，保证当前通信的不中断进行。由此提高整个通信链路的可靠性。示例性的，以RAN1为主接入网设备，RAN2为辅接入网设备为例。RAN1在正常工作时，可以为其配置具有相同小区配置的RAN2，同时RAN2可以向RAN2共享正在工作的终端设备(如第一终端设备)的第一连接参数，以在RAN1出现故障时，RAN2能够快速接管RAN1的工作，进而实现上述增加可靠性的目的。A first aspect provides a data transmission method, the method includes: a first access network device receives first information from a second access network device, the first information includes a first connection parameter of a first terminal device, a second The second access network device communicates with the first terminal device according to the first connection parameter, and the first access network device and the second access network device have the same cell configuration. The first access network device determines that the second access network device is faulty. The first access network device communicates with the first terminal device according to the first connection parameter. Based on this solution, a working mechanism of a secondary access network device (eg, a first access network device) and a primary access network device (eg, a second access network device) is provided. The first access network device may be a secondary access network device, and the second access network device may be a primary access network device. When one access network device (such as the primary access network device) fails, another access network device (such as the secondary access network device) can quickly take over the communication work of the primary access network device, ensuring the current communication uninterrupted. The reliability of the entire communication link is thereby increased. Exemplarily, take RAN1 as the primary access network device and RAN2 as the secondary access network device as an example. When RAN1 is working normally, it can be configured with RAN2 with the same cell configuration, and at the same time, RAN2 can share the first connection parameters of the working terminal equipment (such as the first terminal equipment) with RAN2, so that when RAN1 fails, RAN2 can Quickly take over the work of RAN1, thereby achieving the above-mentioned purpose of increasing reliability.

在一种可能的设计中，该方法还包括：第一接入网设备接收来自第二接入网设备的第二信息，第二信息包括第二接入网设备的小区配置参数，第一接入网设备根据小区配置参数配置第一接入网设备的小区。基于该方案，提供了一种保证第一接入网设备和第二接入网设备具有相同的小区配置的方案。示例性的，RAN1可以向RAN2发送包括其小区配置参数的信息，RAN2可以根据接收到的信息进行小区配置，由此即可保证RAN1和RAN2具有相同的小区配置。In a possible design, the method further includes: the first access network device receives second information from the second access network device, where the second information includes cell configuration parameters of the second access network device, and the first access network device receives second information from the second access network device. The network access device configures the cell of the first access network device according to the cell configuration parameter. Based on this solution, a solution for ensuring that the first access network device and the second access network device have the same cell configuration is provided. Exemplarily, RAN1 may send information including its cell configuration parameters to RAN2, and RAN2 may perform cell configuration according to the received information, thereby ensuring that RAN1 and RAN2 have the same cell configuration.

在一种可能的设计中，该方法还包括：第一接入网设备接收来自第二接入网设备的第三信息，第三信息包括第二终端的第二连接参数。第三信息还包括标识信息，标识信息用于指示第一终端和第二终端是备份关系。基于该方案，提供了一种在第一终端设备存在备份终端时的执行方案。示例性的，由于第一终端设备与RAN1处于通信状态，因此RAN1能够知晓与第一终端设备为备份关系的第二终端设备的连接参数(如第二连接参数)。RAN1可以通过将第二连接参数共享给RAN2，以便RAN2在接管RAN1的工作时能够知晓与第一终端设备为备份关系的第二终端设备的相关参数，并为其提供通信服务。In a possible design, the method further includes: the first access network device receives third information from the second access network device, where the third information includes second connection parameters of the second terminal. The third information further includes identification information, where the identification information is used to indicate that the first terminal and the second terminal are in a backup relationship. Based on this solution, an execution solution when a backup terminal exists in the first terminal device is provided. Exemplarily, since the first terminal device is in a communication state with RAN1, RAN1 can know connection parameters (eg, second connection parameters) of the second terminal device in a backup relationship with the first terminal device. RAN1 may share the second connection parameter with RAN2, so that RAN2 can know the relevant parameters of the second terminal device in a backup relationship with the first terminal device when taking over the work of RAN1, and provide communication services for it.

在一种可能的设计中，该方法还包括：第一接入网设备向第一核心网设备发送第四信息，第四信息用于指示建立第一接入网设备和第一核心网设备之间的第一关联。其中，第四消息携带有第二接入网设备的标识。基于该方案，提供了一种建立RAN2与核心网设备之间的关联的方案。其中，该第一核心网设备可以为5G网络中的AMF，也可以为其他网络中与AMF具有类似功能的网元。示例性的，RAN2可以向AMF发送第四信息，AMF在接收到该第四信息时，由于接收该信息的地址并未保存在其地址列表中，因此AMF就可以知晓该地址为需要新建第一关联的地址。其中，第一关联可以为SCTP关联，或者TNL关联。AMF通过存储该第一关联的地址，即可实现第一关联的建立。In a possible design, the method further includes: the first access network device sends fourth information to the first core network device, where the fourth information is used to instruct to establish a relationship between the first access network device and the first core network device the first relationship between. The fourth message carries the identifier of the second access network device. Based on this solution, a solution for establishing the association between RAN2 and core network equipment is provided. Wherein, the first core network device may be an AMF in a 5G network, or may be a network element having similar functions to the AMF in other networks. Exemplarily, the RAN2 may send the fourth information to the AMF. When the AMF receives the fourth information, since the address for receiving the information is not stored in its address list, the AMF can know that the address needs to be newly created. associated address. The first association may be an SCTP association or a TNL association. The AMF can realize the establishment of the first association by storing the address of the first association.

在一种可能的设计中，在发送第四信息前，该方法还包括：第一接入网设备接收来自第二接入网设备的第一指示信息，第一指示信息用于指示第一接入网设备建立与第一核心网设备之间的第一关联。基于该方案，提供了一种可能的第一关联建立的具体实现。示例性的，RAN2可以在RAN1的指示下，向AMF发送第四信息以便与AMF建立第一关联。在另一些实施例中，RAN2也可以根据其他网元的指示，或者根据预设的规则与AMF建立第一关联。In a possible design, before sending the fourth information, the method further includes: the first access network device receives first indication information from the second access network device, where the first indication information is used to indicate the first access network device. The network access device establishes a first association with the first core network device. Based on this solution, a specific implementation of a possible first association establishment is provided. Exemplarily, under the instruction of RAN1, RAN2 may send the fourth information to the AMF to establish the first association with the AMF. In other embodiments, the RAN2 may also establish the first association with the AMF according to the instructions of other network elements or according to preset rules.

在一种可能的设计中，第四信息还包括第二指示信息，第二指示信息用于指示第一关联对应的地址为非激活状态或挂起状态。基于该方案，提供了一种第一关联的工作机制的方案。示例性的，在RAN1正常工作时，AMF可以不通过该第一关联与RAN2进行信令交互，由此能够减小实现AMF与RAN之间的信令交互。其中，RAN2可以通过发送该第二指示信息，用于指示AMF该第一关联对应的地址不可用(如非激活或挂起状态)。该第二指示信息可以为任意一种能够用于实现上述指示功能的信息，例如off，又如0等。在另一些实施例中，AMF可以默认建立起的第一关联的地址不可用，直到RAN2或其他网元通知AMF该第一关联的地址可用为止。In a possible design, the fourth information further includes second indication information, where the second indication information is used to indicate that the address corresponding to the first association is in an inactive state or a suspended state. Based on the solution, a solution of the working mechanism of the first association is provided. Exemplarily, when the RAN1 is working normally, the AMF may not perform signaling interaction with the RAN2 through the first association, thereby reducing the signaling interaction between the AMF and the RAN. The RAN2 may send the second indication information to indicate to the AMF that the address corresponding to the first association is unavailable (for example, in an inactive or suspended state). The second indication information may be any information that can be used to implement the above indication function, such as off, or 0, and so on. In other embodiments, the address of the first association established by the AMF by default is unavailable until the RAN2 or other network elements notify the AMF that the address of the first association is available.

在一种可能的设计中，在第一接入网设备确定第二接入网设备出现故障之后，该方法还包括：第一接入网设备向第一核心网设备发送第三指示信息，第三指示信息用于指示第一关联对应的地址为激活状态或非挂起状态。基于该方案，在RAN2接管RAN1的工作时，由于需要与AMF进行信令交互以便保证通信链路的通畅，因此，如果第一关联对应的地址在RAN1正常工作时为不可用时，RAN2可以在RAN1故障时向AMF发送用于指示该地址可用(如该地址为激活或非挂起状态)的信息，以便AMF通过该地址与RAN2进行信令交互。可选的，RAN2还可以在RAN1出现故障时，向AMF发送用于指示RAN1对应的地址不可用的信息，或者AMF可以在RAN2指示的地址可用时，将RAN1对应的地址状态修改为不可用，由此在保证AMF与RAN2进行通信的同时，节省AMF与RAN1之间的信令交互。In a possible design, after the first access network device determines that the second access network device is faulty, the method further includes: the first access network device sends third indication information to the first core network device, and the first access network device sends third indication information to the first access network device. The three indication information is used to indicate that the address corresponding to the first association is in an active state or a non-suspended state. Based on this solution, when RAN2 takes over the work of RAN1, it needs to perform signaling interaction with the AMF to ensure the smooth communication link. Therefore, if the address corresponding to the first association is unavailable when RAN1 is working normally, RAN2 can In the event of a failure, the AMF sends information indicating that the address is available (eg, the address is in an active or non-suspended state), so that the AMF can perform signaling interaction with the RAN2 through the address. Optionally, RAN2 may also send information indicating that the address corresponding to RAN1 is unavailable to AMF when RAN1 fails, or AMF may change the state of the address corresponding to RAN1 to unavailable when the address indicated by RAN2 is available, Therefore, while ensuring the communication between the AMF and the RAN2, the signaling interaction between the AMF and the RAN1 is saved.

在一种可能的设计中，在第一接入网设备确定第二接入网设备出现故障之前，该方法还包括：第一接入网设备接收第一上行数据，第一接入网设备启动第一定时器，在第一定时器计时结束后，丢弃第一上行数据，或者，第一接入网设备向第二核心网设备发送第一上行数据。第一接入网设备接收来自第二核心网设备的第一下行数据，启动第二定时器，在第二定时器计时结束后丢弃第一下行数据。基于该方案，当RAN1处于正常工作时，针对上行数据，RAN2可以处于只接收不发送的备份状态，由此能够保证在需要RAN2接管通信时能够快速接管，同时降低RAN1正常工作状态下RAN2与UPF或AMF等核心网元之间的信令交互。In a possible design, before the first access network device determines that the second access network device is faulty, the method further includes: the first access network device receives the first uplink data, and the first access network device starts The first timer discards the first uplink data after the first timer expires, or the first access network device sends the first uplink data to the second core network device. The first access network device receives the first downlink data from the second core network device, starts a second timer, and discards the first downlink data after the second timer expires. Based on this solution, when RAN1 is working normally, for uplink data, RAN2 can be in a backup state that only receives and does not transmit, which can ensure that RAN2 can take over quickly when it is required to take over communication, and at the same time reduce RAN2 and UPF in the normal working state of RAN1. Or signaling interaction between core network elements such as AMF.

在一种可能的设计中，在第一接入网设备接收来自第二核心网设备的第一下行数据之后，该方法还包括：第一接入网设备对第一下行数据进行层2(layer2)编号。基于该方案，RAN2可以在接收到下行数据时，无论是要丢弃该下行数据，或者在一定时间后丢弃该下行数据，或者向终端设备发送该下行数据，RAN2都可以对该数据记性L2编号，以便在RAN2需要接管通信时，下行数据的编号与RAN1相同，由此使得终端设备接收到的数据包不会出现乱序的情况。其中，该L2编号可以是基于PDCP层的编号，也可以基于RLC层的编号。在一些实现方式中，RAN2也可以不对接收到的下行数据进行L2编号。那么在RAN2接管RAN1的通信工作时，可以指示终端设备进行编号初始化，以便在接收到RAN2的数据后能够对其进行正确的解析，由此保证通信的顺利进行，进而提高通信链路的可靠性。In a possible design, after the first access network device receives the first downlink data from the second core network device, the method further includes: the first access network device performs Layer 2 on the first downlink data (layer2) number. Based on this solution, when RAN2 receives downlink data, whether it wants to discard the downlink data, discard the downlink data after a certain period of time, or send the downlink data to the terminal equipment, RAN2 can record the L2 number of the data, So that when the RAN2 needs to take over the communication, the number of the downlink data is the same as that of the RAN1, so that the data packets received by the terminal equipment will not be out of order. The L2 numbering may be based on the numbering of the PDCP layer, or may be based on the numbering of the RLC layer. In some implementation manners, RAN2 may also not perform L2 numbering on the received downlink data. Then, when RAN2 takes over the communication work of RAN1, the terminal equipment can be instructed to initialize the number, so that it can be correctly parsed after receiving the data of RAN2, thereby ensuring the smooth progress of communication and improving the reliability of the communication link. .

在一种可能的设计中，该方法还包括：第一接入网设备停止下行传输，下行传输至少包括随机接入信道(RACH)反馈和/或对第一上行数据进行的ACK/NACK反馈。基于该方案，RAN2可以在RAN1正常工作时，接收到来自终端设备的消息时不对其进行反馈信息的发送，该反馈信息可以包括RACK反馈，ACK/NACK反馈等。由此能够避免RAN2与RAN1的下行传输之间的干扰。In a possible design, the method further includes: the first access network device stops downlink transmission, and the downlink transmission at least includes random access channel (RACH) feedback and/or ACK/NACK feedback for the first uplink data. Based on this solution, when RAN1 is working normally, RAN2 may not send feedback information when it receives a message from a terminal device, and the feedback information may include RACK feedback, ACK/NACK feedback, and the like. As a result, interference between downlink transmissions of RAN2 and RAN1 can be avoided.

在一种可能的设计中，第一接入网设备确定第二接入网设备出现故障，包括：第一接入网设备接收第五信息，第一接入网设备根据第五信息，确定第二接入网设备出现故障。其中，第五信息是与第一终端设备发送的，或者，第五信息是第二接入网设备发送的。基于该方案，提供了一种RAN2确定RAN1出现故障的方法。即，RAN2可以通过接收第五信息，并根据该信息确定ARN1是否出现故障。其中，该第五信息可以为RAN1发送的参考信息，也可以为终端设备发送的参考信息，也可以为终端设备反馈的测量信息等。In a possible design, the first access network device determining that the second access network device is faulty includes: the first access network device receiving fifth information, and the first access network device determining the first access network device according to the fifth information 2. The access network equipment is faulty. The fifth information is sent with the first terminal device, or the fifth information is sent by the second access network device. Based on the solution, a method for RAN2 to determine that RAN1 is faulty is provided. That is, RAN2 can determine whether ARN1 is faulty by receiving the fifth information and according to the information. The fifth information may be reference information sent by RAN1, reference information sent by the terminal device, or measurement information fed back by the terminal device, or the like.

在一种可能的设计中，在第一接入网设备确定第二接入网设备出现故障后，该方法还包括：第一接入网设备向第二接入网设备发送接管指示信息，接管指示信息用于指示第一接入网设备接管与第一终端设备的通信。基于该方案，RAN2可以在确定RAN1出现故障时，通知接管RAN1的通信。可选的，RAN1可以根据该接管指示停止工作。在一些实现方式中，RAN1如果未出现故障，即RAN2出现了故障，则RAN1可以在接收到接管指示信息时，继续工作，并向RAN2反馈用于指示RAN1未发生故障的信息。RAN2可以在接收到该信息后重新根据新接收到的第五信息确定RAN1是否出现故障。并继续保持只接收不进行下行发送的备份状态。In a possible design, after the first access network device determines that the second access network device is faulty, the method further includes: the first access network device sends takeover indication information to the second access network device to take over The indication information is used to instruct the first access network device to take over the communication with the first terminal device. Based on this solution, RAN2 can notify to take over the communication of RAN1 when it is determined that RAN1 is faulty. Optionally, RAN1 may stop working according to the takeover instruction. In some implementations, if RAN1 is not faulty, that is, RAN2 is faulty, RAN1 may continue to work when receiving the takeover indication information, and feed back information indicating that RAN1 is not faulty to RAN2. After receiving the information, RAN2 may re-determine whether RAN1 is faulty according to the newly received fifth information. And continue to maintain the backup state of only receiving and not sending downlink.

在一种可能的设计中，第一接入网设备根据第一连接参数与第一终端设备进行通信，包括：第一接入网设备接收来自第一终端设备的第二上行数据，并将该第二上行数据传输给核心网设备。第一接入网设备接收来自核心网设备的第二下行数据，并将该第二下行数据出传输给第一终端设备。基于该方案，明确了RAN2接管RAN1的通信的方法。即RAN2可以将接收到来自核心网的数据或信令发送给对应的终端设备，RAN2还可以将接收到的来自终端设备的数据或信令发送给对应的核心网设备。In a possible design, the first access network device communicates with the first terminal device according to the first connection parameter, including: the first access network device receives the second uplink data from the first terminal device, and sends the second uplink data to the first terminal device. The second uplink data is transmitted to the core network device. The first access network device receives the second downlink data from the core network device, and transmits the second downlink data to the first terminal device. Based on this solution, the method for RAN2 to take over the communication of RAN1 is clarified. That is, the RAN2 can send the data or signaling received from the core network to the corresponding terminal equipment, and the RAN2 can also send the received data or signaling from the terminal equipment to the corresponding core network equipment.

在一种可能的设计中，第一接入网设备可以根据第五信息确定第二接入网设备是否出现故障。示例性的，在一些实现中，该第五信息可以包括与第二接入网设备进行通信的终端设备发送的信息。例如，该信息可以为ACK/NACK。所述第一接入网设备可以根据第五信息确定第二接入网设备是否出现故障包括：第一接入网设备确定接收到的NACK占比大于第一阈值，则确定第二接入网设备故障。基于该方案，提供了一种RAN2确定RAN1是否出现故障的具体实现。由于RAN2与RNA1具有相同的小区配置，即RAN2与RAN1同频工作，因此在终端设备向RAN1进行ACK/NACK反馈时，RAN2也能接收到该反馈信息，RAN2可以根据接收到的反馈信息中，NACK的占比与第一阈值之间的大小关系，确定RAN1是否出现故障。例如，当NACK的占比大于第一阈值时，则说明UE与RAN1之间的通信存在大量的未完成，由此RAN2可以确定RAN1出现故障。In a possible design, the first access network device may determine whether the second access network device is faulty according to the fifth information. Exemplarily, in some implementations, the fifth information may include information sent by a terminal device that communicates with the second access network device. For example, the information may be ACK/NACK. The first access network device determining whether the second access network device is faulty according to the fifth information includes: the first access network device determines that the proportion of received NACKs is greater than the first threshold, and then determines that the second access network device is faulty. Equipment failure. Based on this solution, a specific implementation for RAN2 to determine whether RAN1 is faulty is provided. Since RAN2 and RNA1 have the same cell configuration, that is, RAN2 and RAN1 work on the same frequency, when the terminal device sends ACK/NACK feedback to RAN1, RAN2 can also receive the feedback information, and RAN2 can receive the feedback information according to the received feedback information. The magnitude relationship between the proportion of NACKs and the first threshold determines whether RAN1 is faulty. For example, when the proportion of NACKs is greater than the first threshold, it means that there is a large number of uncompleted communications between the UE and RAN1, and thus RAN2 can determine that RAN1 is faulty.

在一种可能的设计中，第一接入网设备可以根据第五信息确定第二接入网设备是否出现故障。示例性的，在一些实现中，该第五信息可以包括与第二接入网设备进行通信的终端设备发送的信息。例如，该信息可以为终端设备与第二接入网设备发送的第一参考信息对应的反馈信息。所述反馈信息是所述终端设备对所述第一参考信息进行测量后获取的信息。所述第一接入网设备可以根据第五信息确定第二接入网设备是否出现故障，包括：第一接入网设备根据所述反馈信息，确定第二接入网设备故障。作为一种示例，该第一参考信息可以包括CSI-RS，和/或CSI-IM，和/或DMRS，和/或CRS。该反馈信息可以包括终端设备根据接收到的第一参考信息进行测量后触发获取的事件。该事件可以用于指示参考信息小于对应的预设阈值。基于该方案，提供了又一种RAN2判断RAN1是否出现故障的方案。示例性的，RAN1可以周期性地(或者灵活配置的)向UE发送参考信息，UE可以通过测量该参考信息对应的内容(如CSI-RS，信号功率等)，触发是否生成对应的事件报告。其中，该触发机制可以为当测量结果低于对应的预设阈值时触发的。该事件报告可以用于指示当前测量结果不达标等。RAN2可以通过收集包括事件报告的反馈信息，确定RAN1是否出现故障。In a possible design, the first access network device may determine whether the second access network device is faulty according to the fifth information. Exemplarily, in some implementations, the fifth information may include information sent by a terminal device that communicates with the second access network device. For example, the information may be feedback information corresponding to the first reference information sent by the terminal device and the second access network device. The feedback information is information obtained after the terminal device measures the first reference information. The determining, by the first access network device, whether the second access network device is faulty according to the fifth information, includes: the first access network device determining, according to the feedback information, that the second access network device is faulty. As an example, the first reference information may include CSI-RS, and/or CSI-IM, and/or DMRS, and/or CRS. The feedback information may include an event triggered to acquire after the terminal device performs measurement according to the received first reference information. This event can be used to indicate that the reference information is smaller than the corresponding preset threshold. Based on this solution, another solution for RAN2 to judge whether RAN1 is faulty is provided. Exemplarily, RAN1 may periodically (or flexibly configure) send reference information to the UE, and the UE may trigger whether to generate a corresponding event report by measuring the content (such as CSI-RS, signal power, etc.) corresponding to the reference information. The triggering mechanism may be triggered when the measurement result is lower than the corresponding preset threshold. The event report can be used to indicate that the current measurement result is not up to standard, etc. RAN2 can determine whether RAN1 is faulty by collecting feedback information including event reports.

Exemplarily, in some implementations, the fifth information may include second reference information sent by the second access network device. The first access network device may determine whether the second access network device is faulty according to the fifth information, including: the first access network device measures the received second reference information, and when the reference information is less than a corresponding threshold is determined, the second access network device is faulty. Based on this solution, another solution for RAN2 to judge whether RAN1 is faulty is provided. Exemplarily, RAN2 may periodically receive reference information sent by RAN1, and actively measure the reference information.

具体实施方式detailed description

目前，由于业务对应的通信链路的可靠性无法满足业务对于可靠性的要求，而其瓶颈之一为通信链路上设备(如单个基站)的可靠性不足。因此可以同时配置两个通信链路同步为单个业务提供通信服务，以便提升整体的可靠性。At present, since the reliability of the communication link corresponding to the service cannot meet the reliability requirements of the service, one of the bottlenecks is the insufficient reliability of the equipment (eg, a single base station) on the communication link. Therefore, two communication links can be configured simultaneously to provide communication services for a single service, so as to improve the overall reliability.

示例性的，请参考图1，为一种通信架构的示意图。其中，以应用层实体与数据网络(data net，DN)进行业务通信为例。Exemplarily, please refer to FIG. 1 , which is a schematic diagram of a communication architecture. Among them, the business communication between the application layer entity and the data network (data net, DN) is taken as an example.

如图1所示，在该通信架构中，可以在应用层实体与DN之间搭设两套完整的接入链路，其中，一个接入链路可以包括一个终端设备(如图1中的UE1或UE2)，一个基站(如图1中的RAN1或RAN2)，一个用户面功能实体(如图1中的UPF1或UPF2)。应用层实体在于DN进行通信时，可以将对应的信令分别通过两个接入链路传输处理，以便当一个接入链路出现故障时，另一个接入链路能够保证通信的不中断。由此提升通信链路的可靠性。As shown in Figure 1, in this communication architecture, two complete sets of access links can be set up between the application layer entity and the DN, wherein one access link can include a terminal device (UE1 in Figure 1 ). or UE2), a base station (such as RAN1 or RAN2 in FIG. 1 ), and a user plane functional entity (such as UPF1 or UPF2 in FIG. 1 ). When the application layer entity communicates with the DN, the corresponding signaling can be transmitted and processed through the two access links respectively, so that when one access link fails, the other access link can ensure uninterrupted communication. The reliability of the communication link is thereby improved.

然而，该方案虽然能够通过两个接入链路同时工作实现可靠性的提升，但是由于需要两套完整的接入链路上的设备(如两个UE，两个RAN，以及两个UPF)，因此会带来显著的硬件成本的提升。另外，由于两个UE需要在不同的频率(如图1所示的f1以及f2)下与不同的RAN进行数据交互，因此也会导致频谱资源的浪费。However, although this solution can improve reliability through the simultaneous operation of two access links, it requires two complete sets of equipment on the access links (such as two UEs, two RANs, and two UPFs). , so it will bring a significant increase in hardware cost. In addition, since the two UEs need to perform data interaction with different RANs at different frequencies (f1 and f2 as shown in FIG. 1 ), it will also lead to waste of spectrum resources.

请参考图2，为另一种通信架构的示意图。其中，以UE与DN进行业务通信为例。Please refer to FIG. 2 , which is a schematic diagram of another communication architecture. The service communication between the UE and the DN is taken as an example.

如图2所示，在该架构下，终端设备(如图2所示的UE)可以分别在f1和f2下，与包括RAN1和UPF1的链路1，以及包括RAN2和UPF2的链路2进行数据交互。这样，当UE需要访问DN时，可以同时通过链路1以及链路2与DN进行交互，以便在一个链路出现问题时，由于另一个链路的存在，保证通信不中断。由此提升通信链路的可靠性。As shown in Fig. 2, under this architecture, a terminal device (UE as shown in Fig. 2) can communicate with link 1 including RAN1 and UPF1 and link 2 including RAN2 and UPF2 under f1 and f2, respectively. Data interaction. In this way, when the UE needs to access the DN, it can interact with the DN through the link 1 and the link 2 at the same time, so that when a problem occurs on one link, the existence of the other link ensures that the communication is not interrupted. The reliability of the communication link is thereby improved.

但是，该方案依然存在问题。例如，与图1所示方案类似，该方案中的两个链路上都需要分别接入网设备以及用户面功能实体，因此会导致硬件成本的提升。同时由于UE需要同时在f1和f2下进行相同的业务通信，因此会导致频谱资源的浪费。另外，在该方案中，由于两个接入网设备(如RAN1和RAN2)一般采用双连接(Dual connectivity，DC)形式，因此当一个接入网设备出现故障时，另一个接入网设备也无法正常工作。However, there are still problems with this scheme. For example, similar to the solution shown in FIG. 1 , the two links in this solution need to access network equipment and user plane functional entities respectively, which will lead to an increase in hardware cost. At the same time, because the UE needs to perform the same service communication under f1 and f2 at the same time, it will lead to waste of spectrum resources. In addition, in this solution, since two access network devices (such as RAN1 and RAN2) generally adopt the form of dual connectivity (Dual connectivity, DC), when one access network device fails, the other access network device also unable to work properly.

为了解决上述问题，本申请实施例提供一种数据的传输方法，能够在适当节省硬件成本以及频谱资源的前提下，使得在第一接入网设备出现故障时，第二接入网设备可以顺利地接管业务，保证业务不中断，由此达到提升通信链路可靠性的目的。In order to solve the above problem, an embodiment of the present application provides a data transmission method, which can properly save hardware costs and spectrum resources, so that when the first access network device fails, the second access network device can smoothly It can take over the business and ensure that the business is not interrupted, thereby achieving the purpose of improving the reliability of the communication link.

Wherein, N is 1, that is, there is at least one terminal device (such as UE1) within the coverage area of the corresponding cell of the access network device 1 that has a service communication requirement as an example. As shown in FIG. 4 , the terminal device (UE1 in FIG. 4 ) can establish a communication link with the core network through the RAN1, the AMF and the UPF. This enables the UE to establish a service communication link with the DN through the AMF and/or the UPF.

在另一些实现方式中，该小区配置参数可以包括以下信息中的一个或多个：***消息以及相应时频资源；参考符号以及相应时频资源；小区标识(如PCI、CGI等)；主站的网际互连协议(internet protocol，IP)地址。In other implementation manners, the cell configuration parameters may include one or more of the following information: system messages and corresponding time-frequency resources; reference symbols and corresponding time-frequency resources; cell identifiers (such as PCI, CGI, etc.); primary station Internet Protocol (IP) address.

这样，RAN2可以根据RAN1发送的小区配置参数对其小区进行配置，以便在RAN1出现故障时，可以实现与UE1的通信。示例性的，RAN2可以根据RAN1发送的配置信息(如小区配置参数)进行小区配置后，实现了相同小区配置和覆盖。另外，因为RAN2获得了UE的第一连接参数，因此当RAN1故障时，RAN2可以实现对于UE的无感知接管。即UE业务连续不中断。In this way, the RAN2 can configure its cell according to the cell configuration parameter sent by the RAN1, so that when the RAN1 fails, the communication with the UE1 can be realized. Exemplarily, after RAN2 may perform cell configuration according to the configuration information (eg, cell configuration parameters) sent by RAN1, the same cell configuration and coverage are implemented. In addition, because the RAN2 obtains the first connection parameter of the UE, when the RAN1 fails, the RAN2 can implement a non-aware takeover for the UE. That is, UE services are continuous and uninterrupted.

需要说明的是，在本示例中的不同实现场景下，RAN1和RAN2也可以有相同或不同的频率部署。RAN1和RAN2可以全带宽备份，也可以频谱部分共享。例如，以频谱带宽为100兆赫兹(MHz)为例。RAN1可以使用前50MHz工作，后50MHz对RAN2进行备份。类似的，RAN2可以使用前50MHz对RAN1进行备份，后50MHz对其他UE提供服务。It should be noted that, in different implementation scenarios in this example, RAN1 and RAN2 may also have the same or different frequency deployments. RAN1 and RAN2 can be backed up in full bandwidth, or can share part of the spectrum. For example, consider a spectral bandwidth of 100 megahertz (MHz). RAN1 can use the first 50MHz to work, and the latter 50MHz to back up RAN2. Similarly, RAN2 can use the first 50MHz to back up RAN1, and the last 50MHz to serve other UEs.

另外，在不同的实现场景下，两个基站(如RAN1和RAN2)可以标识相同，也可以不同。当基站标识(如gNB ID)不同时，RAN1和RAN2可以通过UE标识协商，即将UE标识池进行分配，使得当备份基站接管时，UE标识不会重复。具体的一种可能实现的方式为，RAN1将RAN UE NGAP ID一个子集用于其覆盖下的UE，将其余的可用ID标识发送给RAN2。In addition, in different implementation scenarios, the two base stations (eg, RAN1 and RAN2) may have the same identifiers or different identifiers. When the base station identities (such as gNB IDs) are different, RAN1 and RAN2 can negotiate through UE identities, that is, allocate a pool of UE identities, so that when the backup base station takes over, the UE identities will not be repeated. A specific possible implementation method is that RAN1 uses a subset of RAN UE NGAP IDs for UEs under its coverage, and sends the remaining available ID identifiers to RAN2.

基于上述图6的说明，应当理解的是，RAN2通过RAN1共享的小区配置参数以及UE1(UE1和UE2)的连接参数，就可以实现RAN2与UE之间的数据传输。由此实现当RAN1出现故障时，RAN2能够顺利接管RAN1与UE之间的通信，以提高对应链路的可靠性。需要说明的是，在实际执行过程中，图6中的信息1和信息2可以是通过同一个消息进行发送的，也可以是通过不同消息进行发送的。另外，该信息1和信息2可以是同步发送的，也可以是异步发送的。在异步发送时，其先后顺序可以根据实际需要灵活调整。在不同的实现场景下，上述信息1和/或信息2可以是周期性发送消息，也可以是事件触发的。例如，具体的用于触发信息的发送的事件可以包括：当UE接入建立RRC连接，则第一RAN向第二RAN发送RRC相关配置信息，如第一连接参数。本申请实施例对此不作限制。Based on the above description of FIG. 6 , it should be understood that the RAN2 can implement data transmission between the RAN2 and the UE through the cell configuration parameters shared by the RAN1 and the connection parameters of the UE1 (UE1 and UE2). Therefore, when the RAN1 fails, the RAN2 can smoothly take over the communication between the RAN1 and the UE, so as to improve the reliability of the corresponding link. It should be noted that, in the actual execution process, the information 1 and the information 2 in FIG. 6 may be sent through the same message, or may be sent through different messages. In addition, the information 1 and the information 2 may be sent synchronously or asynchronously. When sending asynchronously, its sequence can be flexibly adjusted according to actual needs. In different implementation scenarios, the above-mentioned information 1 and/or information 2 may be sent periodically or triggered by an event. For example, the specific event for triggering the sending of information may include: when the UE accesses and establishes an RRC connection, the first RAN sends RRC-related configuration information, such as the first connection parameter, to the second RAN. This embodiment of the present application does not limit this.

在本申请实施例的一些实现方式中，RAN2还可以与第一核心网设备(如图4所示的AMF)进行交互，以便建立RAN2与控制面的数据传输通道。在本申请实施例的另一些实现方式中，RAN2还可以与第二核心网设备(如图4所示的UPF)进行交互，以便建立RAN2与用户面的数据传输通道。In some implementations of the embodiments of the present application, the RAN2 may also interact with the first core network device (the AMF shown in FIG. 4 ), so as to establish a data transmission channel between the RAN2 and the control plane. In other implementation manners of the embodiments of the present application, RAN2 may also interact with a second core network device (the UPF shown in FIG. 4 ), so as to establish a data transmission channel between RAN2 and the user plane.

示例性的，请参考图7，RAN2可以向AMF发送信息3(即执行S701)。实现与AMF之间的数据传输通道的建立。本申请实施例中，还可将该数据传输通道的建立称为第一关联(association)的建立。其中，该第一关联可以为流控制传输协议(stream control transmission protocol，SCTP)关联，或者传输网络层(transport network layer，TNL)关联，或者其他可以用于AMF与RAN2之间进行通信的关联。Exemplarily, please refer to FIG. 7 , RAN2 may send information 3 to the AMF (ie, perform S701). Realize the establishment of data transmission channel with AMF. In this embodiment of the present application, the establishment of the data transmission channel may also be referred to as establishment of a first association (association). Wherein, the first association may be a stream control transmission protocol (stream control transmission protocol, SCTP) association, or a transport network layer (transport network layer, TNL) association, or other associations that can be used for communication between AMF and RAN2.

应当理解的是，AMF可以在RAN2对应的地址(如称为地址2)接收到该信息3，AMF确认该地址2并未保存在其地址列表中，即可确定该地址2为新增的第一关联的地址。需要说明的是，该信息3还可以携带有RAN1的标识(如RAN1对应的global gNB ID)，以便AMF能够根据该信息3，确定接收到该信息3的地址2为与RAN1的地址(如地址1)对应的接入网设备为逻辑上的同一个接入网设备。It should be understood that the AMF can receive the information 3 at the address corresponding to RAN2 (such as address 2), and the AMF confirms that the address 2 is not stored in its address list, and can then determine that the address 2 is the newly added No. an associated address. It should be noted that the information 3 can also carry the identifier of RAN1 (such as the global gNB ID corresponding to RAN1), so that the AMF can determine, according to the information 3, that the address 2 that received the information 3 is the same as the address of RAN1 (such as the address 1) The corresponding access network device is logically the same access network device.

在一些实施例中，RAN2可以在RAN1与AMF建立连接(如基于NG-C接口的连接)后，直接向AMF发送上述信息3，以建立与AMF之间的第一关联。示例性的，该信息3可以通过RRC Configuration update消息传输。在一些场景下，AMF收到该消息后，可以回复响应消息。作为一种可能的实现方式，RAN2还可以向AMF发送指示信息1(即执行如图7所示的S702)，用于指示该地址2为非激活或挂起状态，以便AMF可以在存储该地址2的同时，暂时不通过该地址2下发数据，起到节省信令开销的目的。对应的，在RAN2确定RAN1出现故障(即执行如图7所示的S703)时，则RAN2可以向AMF发送指示信息2(即执行如图7所示的S704)，以便AMF根据该指示信息2，确定地址2为激活或非挂起状态，进而使得AMF通过该地址2向RAN2进行数据传输，达到RAN2接管RAN1与AMF之间通信的目的。作为一种可能的实现方式，在RAN2向AMF发送指示信息2时，RAN2还可以向AMF发送指示信息3，用于指示RAN1对应的地址1为非激活或挂起状态或者对该地址进行删除，以便在RAN1出现故障时，节省向RAN1的信令开销。一种可能的方式为，在RAN2向AMF发送消息4之前，RAN2收到RAN1发送的指示信息，该指示信息用于指示RAN2建立与AMF之间的第一关联。需要说明的是，在一些实现场景下，RAN2可以通过发送对应的消息，以建立与AMF之间的第一关联。例如，该消息可以为RRC Configuration update消息，或者其他能够实现对应功能的消息。由此，使得主站故障后，RAN1与AMF之间的连接快速平滑的由RAN2代替RAN1接管，保证了控制面不中断。In some embodiments, after RAN1 establishes a connection with the AMF (eg, a connection based on the NG-C interface), the RAN2 may directly send the above-mentioned information 3 to the AMF to establish the first association with the AMF. Exemplarily, the information 3 may be transmitted through the RRC Configuration update message. In some scenarios, the AMF can reply with a response message after receiving the message. As a possible implementation manner, RAN2 may also send indication information 1 to the AMF (that is, perform S702 as shown in FIG. 7 ) to indicate that the address 2 is in an inactive or suspended state, so that the AMF can store the address At the same time as 2, the data is not sent through the address 2 temporarily, so as to save the signaling overhead. Correspondingly, when RAN2 determines that RAN1 is faulty (that is, performing S703 as shown in FIG. 7 ), RAN2 may send indication information 2 to the AMF (that is, performing S704 as shown in FIG. 7 ), so that the AMF can perform S704 as shown in FIG. , determine that the address 2 is in the active or non-suspended state, and then enable the AMF to transmit data to the RAN2 through the address 2, so that the RAN2 takes over the communication between the RAN1 and the AMF. As a possible implementation manner, when RAN2 sends indication information 2 to AMF, RAN2 may also send indication information 3 to AMF, which is used to indicate that address 1 corresponding to RAN1 is in an inactive or suspended state or delete the address, In order to save the signaling overhead to RAN1 when RAN1 fails. A possible way is that before RAN2 sends message 4 to the AMF, RAN2 receives the indication information sent by RAN1, where the indication information is used to instruct RAN2 to establish the first association with the AMF. It should be noted that, in some implementation scenarios, the RAN2 may establish the first association with the AMF by sending a corresponding message. For example, the message may be an RRC Configuration update message, or other messages capable of implementing corresponding functions. Therefore, after the master station fails, the connection between RAN1 and AMF is quickly and smoothly taken over by RAN2 instead of RAN1, which ensures that the control plane is not interrupted.

在另一些实施例中，RAN2还可以是在确定RAN1故障后，才发送上述信息3，或信息3和指示信息3。In other embodiments, the RAN2 may also send the above-mentioned information 3, or the information 3 and the indication information 3 after determining that the RAN1 is faulty.

在另一些实施例中，RAN2还可以通过RAN1发送上述信息3，或信息3和指示信息1，或信息3和指示信息1和指示信息2，或信息3和指示信息1和指示信息2和指示信息3。In other embodiments, RAN2 may also send the above information 3, or information 3 and indication information 1, or information 3 and indication information 1 and indication information 2, or information 3 and indication information 1 and indication information 2 and indication through RAN1 Information 3.

在另一种实施例中，RAN2可以在确定RAN1故障之后，向AMF发送上述信息3，建立与AMF之间的第一关联。RAN2还可以向AMF发送指示删除RAN1对应地址的信息，由此实现RAN2与AMF的快速建立关联。In another embodiment, after determining that the RAN1 is faulty, the RAN2 may send the above-mentioned information 3 to the AMF to establish the first association with the AMF. RAN2 may also send information indicating deletion of the address corresponding to RAN1 to AMF, thereby realizing rapid association between RAN2 and AMF.

在另一种实施例中，RAN1和RAN2同时保持和AMF的关联，即当RAN2建立关联关系(如第一关联)后，RAN2可以向AMF发送指示该关联为备份关联的信息。AMF收到指示信息后，可以同时向RAN1和RAN2发送信令。在一些实现方式中，RAN2可以对接收到的来自AMF的数据(如来自AMF的信令)执行以下处理：当RAN1故障前，RAN2基于定时器保存信令，超时丢弃，或者向RAN1转发。当确定RAN1故障后，则向UE发送从AMF收到的信令。In another embodiment, RAN1 and RAN2 maintain the association with the AMF at the same time, that is, after RAN2 establishes an association relationship (eg, the first association), RAN2 may send information indicating that the association is a backup association to the AMF. After the AMF receives the indication information, it can send signaling to RAN1 and RAN2 at the same time. In some implementations, RAN2 may perform the following processing on received data from AMF (eg, signaling from AMF): before RAN1 fails, RAN2 saves the signaling based on a timer, discards it over time, or forwards it to RAN1. When it is determined that the RAN1 is faulty, the signaling received from the AMF is sent to the UE.

由此，即可建立RAN2与AMF之间的控制面数据传输通道。Thus, the control plane data transmission channel between RAN2 and AMF can be established.

在本申请实施例中，RAN2还可以与UPF建立用户面数据传输通道。In this embodiment of the present application, the RAN2 may also establish a user plane data transmission channel with the UPF.

示例性的，在高可靠低延迟通信(ultra-reliable and low latency communication，URLLC)建立时，可以建立对应的QoS流(flow)。此时，UPF可以分别为RAN1和RAN2分配两个地址，这两个地址可以为面向UPF的地址。UPF可以将这两个地址通过SMF和AMF发送给RAN1。RAN1可以将其中的一个地址发送给RAN2，以便RAN2能够知晓UPF的地址，进而根据该地址进行数据的上行发送。RAN1还可以获取RAN2的地址，并将RAN1和RAN2的地址一并(或分别)发送给UPF，以便UPF能够知晓RAN1和RAN2的地址，进而通过该地址实现数据的下行发送。由此，即可建立UPF与RAN1和RAN2之间的用户面双通道。实现了RAN与UPF的双路径，提高了传输的可靠性和低时延。Exemplarily, when a highly reliable and low latency communication (ultra-reliable and low latency communication, URLLC) is established, a corresponding QoS flow (flow) may be established. At this time, the UPF may allocate two addresses to RAN1 and RAN2 respectively, and the two addresses may be UPF-oriented addresses. UPF can send these two addresses to RAN1 via SMF and AMF. RAN1 may send one of the addresses to RAN2, so that RAN2 can know the address of the UPF, and then perform uplink transmission of data according to the address. RAN1 can also obtain the address of RAN2, and send the addresses of RAN1 and RAN2 together (or separately) to the UPF, so that the UPF can know the addresses of RAN1 and RAN2, and then realize the downlink transmission of data through the address. Thus, the user plane dual channels between the UPF and RAN1 and RAN2 can be established. The dual path of RAN and UPF is realized, which improves the reliability and low delay of transmission.

需要说明的是，上述示例中，是以通过RAN1转发UPF为RAN2分配的地址，同时通过RAN1向UPF上报RAN2的第十为例进行说明的。在另一些实施例中，UPF为RAN2分配的地址还可通过其他网元转发给RAN2，RAN2的地址也可通过其他网元发送给UPF。本申请实施例对此不作限制。It should be noted that, in the above example, the RAN1 forwards the address allocated by the UPF to the RAN2, and simultaneously reports the tenth address of the RAN2 to the UPF through the RAN1 as an example for description. In other embodiments, the address allocated by UPF to RAN2 may also be forwarded to RAN2 through other network elements, and the address of RAN2 may also be sent to UPF through other network elements. This embodiment of the present application does not limit this.

由此，结合上述图6以及图7以及对于UPF相关数据传输通道的建立的说明，RAN2就实现了对于终端设备(如UE1)，以及对核心网设备(如AMF，以及UPF)的数据传输通道的建立。也就是说，当RAN1出现故障时，RAN2就具备了接管RAN1的通信(如上行数据的传输和/或下行数据的传输)的能力。Therefore, in combination with the above-mentioned Figures 6 and 7 and the description of the establishment of the UPF-related data transmission channel, RAN2 realizes the data transmission channel for terminal equipment (such as UE1) and core network equipment (such as AMF, and UPF). establishment. That is, when RAN1 fails, RAN2 has the ability to take over the communication of RAN1 (eg, transmission of uplink data and/or transmission of downlink data).

需要说明的是，上述图6所示的方法，图7所示的方法，以及对于UPF相关数据传输通道的建立方法，其执行的先后顺序可以按照实际需要灵活设置，本申请实施例对此不作限制。It should be noted that, for the method shown in FIG. 6 , the method shown in FIG. 7 , and the method for establishing a UPF-related data transmission channel, the order of execution can be flexibly set according to actual needs, which is not made in this embodiment of the present application. limit.

另外，在本申请的一些实施例中，RAN2在建立了上述与UE1，以及与AMF和UPF的通信能力之后，当RAN1未发生故障时，RAN2不需要进行上下行数据的全量处理与发送，因此可以处于只接收不发送的状态。In addition, in some embodiments of the present application, after RAN2 establishes the above-mentioned communication capabilities with UE1, as well as with AMF and UPF, when RAN1 does not fail, RAN2 does not need to perform full processing and transmission of uplink and downlink data. Therefore, It can be in the state of only receiving but not sending.

示例性的，在一些实现方式中，RAN2可以接收第一上行数据，该第一上行数据可以是UE1发送的数据。RAN2可以启动其中的第一定时器，在该第一定时器计时结束后，即丢弃该第一上行数据。由此可以有效节省RAN2与UPF或AMF之间的信令开销。Exemplarily, in some implementation manners, RAN2 may receive first uplink data, where the first uplink data may be data sent by UE1. The RAN2 may start the first timer, and after the first timer expires, the first uplink data is discarded. Thereby, signaling overhead between RAN2 and UPF or AMF can be effectively saved.

示例性的，在一些实现方式中，RAN2可以接收第一上行数据，并将接收的第一上行数据发送给核心网设备(如UPF)，UPF从RAN1和RAN2接收到相同的数据，可以通过GTP-U SN号进行冗余去重。Exemplarily, in some implementations, RAN2 may receive the first uplink data, and send the received first uplink data to a core network device (such as UPF). The UPF receives the same data from RAN1 and RAN2, and can use GTP -USN number for redundant deduplication.

在另一些实现方式中，RAN2可以接收第一下行数据，该第一下行数据可以为UPF发送的数据。RAN2可以启动第二定时器，在该第二定时器计时结束后，即丢弃该第一下行数据。由此可以有效节省RAN2与UE1之间的信令开销，避免对RAN1于UE传输产生干扰。需要说明的是，在该示例的另一种设计中，RAN2在接收到该第一下行数据之后，也可以将该第一下行数据传输给UE1。可以理解的是，一般而言，核心网设备(如UPF)与接入网设备(如RAN2)之间可以通过有线的方式进行数据传输，因此具有较高的传输质量。而接入网设备与终端设备之间的数据传输一般可以采用无线传输的形式，由于空间干扰等问题的存在，数据传输的过程中容易出现掉包等问题。因此，在该设计中，当RAN2接收到第一下行数据后，可以将该数据转发给UE1，UE1同时还可接收到来自RAN1的数据。进而使得UE1可以通过接收到两份相同的数据，实现提升数据传输质量的目的。In other implementation manners, the RAN2 may receive the first downlink data, where the first downlink data may be data sent by the UPF. The RAN2 may start a second timer, and after the second timer expires, the first downlink data is discarded. In this way, signaling overhead between RAN2 and UE1 can be effectively saved, and interference to transmission between RAN1 and UE1 can be avoided. It should be noted that, in another design of this example, after receiving the first downlink data, the RAN2 may also transmit the first downlink data to the UE1. It can be understood that, generally speaking, data transmission between the core network device (such as UPF) and the access network device (such as RAN2) can be performed in a wired manner, and thus has higher transmission quality. The data transmission between the access network device and the terminal device can generally be in the form of wireless transmission. Due to the existence of problems such as spatial interference, problems such as packet loss are prone to occur in the process of data transmission. Therefore, in this design, after RAN2 receives the first downlink data, it can forward the data to UE1, and UE1 can also receive data from RAN1 at the same time. In this way, UE1 can achieve the purpose of improving data transmission quality by receiving two identical pieces of data.

其中，上述示例中的第一定时器对应的时长与第二定时器对应的时长可以是预先设置的，也可以是灵活配置的。例如，可以在RAN2中为UE1建立备份数据无线承载(data radio bearer，DRB)，在接收到第一上行数据时，根据第一定时器对应的时长，或者该第一上行数据携带的时间戳，执行对该数据的丢弃。又如，RAN2可以在收到第一下行数据后，进行PDCP缓存后，根据第二定时器对应的时长执行对其的丢弃操作，或进行下行传输，也可以根据下行数据携带的时间戳以及该包的有效时间对该包进行超时丢弃，比如0时刻接收该数据包，该包有效时间为两毫秒，则到2毫秒时，RAN2可以进行丢弃。例如，该第二定时器的时长可以由预设的(或核心网设备配置的)数据包延迟预算(packet delay budget，PDB)或接入网络PDB(access network packet delay budget，AN-PDB)确定。当RAN2判断RAN1出现故障后，停止对接收的下行数据包丢弃，将缓存的全部数据包或者根据有效时间将缓存的部分数据包发送给UE1。The duration corresponding to the first timer and the duration corresponding to the second timer in the above example may be preset or flexibly configured. For example, a backup data radio bearer (DRB) may be established for UE1 in RAN2, and when the first uplink data is received, according to the duration corresponding to the first timer, or the time stamp carried by the first uplink data, A discard of this data is performed. For another example, after receiving the first downlink data, RAN2 may perform PDCP buffering and discard it according to the duration corresponding to the second timer, or perform downlink transmission, or may perform downlink transmission according to the time stamp carried by the downlink data and The valid time of the packet is overtime and the packet is discarded. For example, when the packet is received at time 0, and the packet is valid for two milliseconds, RAN2 can discard it when it reaches 2 milliseconds. For example, the duration of the second timer may be determined by a preset (or configured by a core network device) packet delay budget (packet delay budget, PDB) or an access network packet delay budget (AN-PDB) . When RAN2 determines that RAN1 is faulty, it stops discarding the received downlink data packets, and sends all the buffered data packets or some of the buffered data packets to UE1 according to the valid time.

需要说明的是，在本申请实施例中，RAN2在接收到来自UE的上行数据，或者来自UPF的下行数据时，可以停止下行传输。其中，该下行传输至少可以包括以下数据传输中的一种或多种：随机接入信道(random access channel，RACH)反馈，对上行数据的ACK/NACK反馈等。应当理解的是，接入网设备在接收到上行数据时，会进行对应的反馈，以便UE能够知晓对应上行数据的传输状态。而在本申请实施例中，由于在RAN1未出现故障时，RAN2仅为备份使用，因此，RAN2可以关闭针对接收到的UE发送的上行数据进行的反馈。由此减小RAN2发送信息对RAN1正常通信的干扰。同时也能够节省RAN2与UE之间的信令开销。在本申请实施例中，当RAN1正常工作(及没有出现故障)时，RAN2所处的只接收数据，不进行下行数据的发送的状态，也可以称为备份状态，或者备份工作状态。It should be noted that, in this embodiment of the present application, the RAN2 may stop downlink transmission when receiving uplink data from the UE or downlink data from the UPF. The downlink transmission may include at least one or more of the following data transmissions: random access channel (random access channel, RACH) feedback, ACK/NACK feedback for uplink data, and the like. It should be understood that when the access network device receives the uplink data, it will perform corresponding feedback, so that the UE can know the transmission status of the corresponding uplink data. However, in this embodiment of the present application, since RAN2 is only used for backup when RAN1 is not faulty, RAN2 may disable feedback on the received uplink data sent by the UE. Therefore, the interference of the information sent by RAN2 to the normal communication of RAN1 is reduced. At the same time, the signaling overhead between RAN2 and the UE can be saved. In the embodiment of the present application, when RAN1 works normally (and no fault occurs), the state in which RAN2 only receives data and does not send downlink data may also be called a backup state or a backup working state.

另外，在本申请的一些实施例中，RAN2可以对接收到的下行数据进行编码或者数据处理，以便当RAN1出现故障时，RAN2可以将携带有正确编码的数据下发给UE，进而使得UE能够根据该编码，对从RAN2接收到的数据以及从RAN1接收到的数据进行正确的解析。示例性的，参考图4和图5，RAN1中的BBU1，以及RAN2中的BBU2，两个BBU的PDCP PDU SN号可以设置为相同或相关，以便RAN2在接收到下行数据时，能够与RAN1对该数据进行同步编号。例如，RAN2可以根据GTP-U SN对接收到的数据进行排序。在另一些实施例中，为了保证UE接收到信息的唯一性和连续性，也可通过RAN1和RAN2之间的周期性(或根据信令)SN号同步，实现下行数据的同步编号，即RAN1可以将数据包对应PDCP SN号和GTP-U SN号发送给RAN2。在另一些实施例中，当RAN1发现接收的数据包丢失时，比如GTP-U包出现空洞，则通知RAN2，RAN2则将当前数据包序号进行减1，如果RAN2接收数据包发生丢失，则在接收空洞包的下一个数据包时，将SN号加1。这样的调整使得PDCP数据包的SN编号在RAN1和RAN2一致，便于UE在备站接管后，接收的数据可以保持连续性，重复接收的包可以进行冗余删除。实现了终端业务的连续性。In addition, in some embodiments of the present application, the RAN2 may encode or process the received downlink data, so that when the RAN1 fails, the RAN2 can deliver the correctly encoded data to the UE, so that the UE can According to this encoding, the data received from RAN2 and the data received from RAN1 are correctly parsed. Exemplarily, referring to FIG. 4 and FIG. 5 , BBU1 in RAN1 and BBU2 in RAN2, the PDCP PDU SN numbers of the two BBUs can be set to be the same or related, so that RAN2 can communicate with RAN1 when receiving downlink data. The data is synchronized numbered. For example, RAN2 can sort the received data according to the GTP-USN. In other embodiments, in order to ensure the uniqueness and continuity of the information received by the UE, the synchronization number of the downlink data can also be realized through periodic (or according to signaling) SN number synchronization between RAN1 and RAN2, that is, RAN1 The data packet corresponding to the PDCP SN number and the GTP-US SN number can be sent to RAN2. In other embodiments, when RAN1 finds that the received data packet is lost, such as a hole in the GTP-U packet, it notifies RAN2, and RAN2 decrements the current data packet sequence number by 1. When receiving the next data packet of the hole packet, increment the SN number by 1. This adjustment makes the SN numbers of the PDCP data packets consistent between RAN1 and RAN2, so that after the UE takes over the standby station, the received data can maintain continuity, and the repeatedly received packets can be redundantly deleted. The continuity of terminal business is realized.

在另一些实施例中，RAN2可以对RLC进行正常SN编号，也可以不对接收到的下行数据进行编号，而在确定接管RAN1的通信之后，向对应的UE发送RLC初始化指令，以便UE对其接受到的数据的序号进行初始化，进而对接下来接收到的RAN2的数据进行正确的解析。此外PDCP层也可以适用该方式，即可以通过RAN2发送信令，对UE进行PDCP层进行初始化，后续数据从0或者1开始编排。实现了终端业务的连续性。In other embodiments, RAN2 may perform normal SN numbering on the RLC, or may not number the received downlink data, and after determining to take over the communication of RAN1, send an RLC initialization instruction to the corresponding UE, so that the UE can accept it. The serial number of the received data is initialized, and then the data of the RAN2 received next is correctly parsed. In addition, this method can also be applied to the PDCP layer, that is, signaling can be sent through RAN2 to initialize the PDCP layer of the UE, and subsequent data are arranged from 0 or 1. The continuity of terminal business is realized.

通过上述说明，本领域技术人员应当理解，RAN2通过上述处理已经具备了在RAN1出现故障时，接管RAN1与UE1之间的通信的能力。本申请实施例还提供多种不同的方法，使得RAN2能够自主确定RAN1是否发送故障，进而执行通信接管的操作。From the above description, those skilled in the art should understand that RAN2 already has the ability to take over the communication between RAN1 and UE1 when RAN1 fails through the above process. The embodiments of the present application also provide a variety of different methods, so that the RAN2 can autonomously determine whether the RAN1 sends a fault, and then perform the operation of taking over the communication.

示例性的，在一些实施例中，RAN2可以接收来自UE的信息，并根据UE反馈的信息，确定RAN1是否出现故障。Exemplarily, in some embodiments, the RAN2 may receive information from the UE, and determine whether the RAN1 is faulty according to the information fed back by the UE.

例如，该信息可以为UE反馈的ACK/NACK。应当理解的是，大部分UE相关业务均为周期性业务，UE会根据与其保持通信的接入网设备(如RAN1)发送的信息进行ACK/NACK反馈。由于RAN2处于能够接收信息的状态，因此RAN2能够接收到与RAN1保持通信的多个UE上报的ACK/NACK的情况。当RAN2在某个周期接收到的NACK占比超过第一阈值(如80％)时，则RAN2确定RAN1出现故障。For example, the information may be ACK/NACK fed back by the UE. It should be understood that most UE-related services are periodic services, and the UE will perform ACK/NACK feedback according to information sent by an access network device (eg, RAN1) that maintains communication with it. Since RAN2 is in a state of being able to receive information, RAN2 can receive ACK/NACK reported by multiple UEs that are in communication with RAN1. When the proportion of NACKs received by RAN2 in a certain period exceeds the first threshold (eg, 80%), then RAN2 determines that RAN1 is faulty.

在另一些实施例中，RAN2可以接收来自UE的第一测量信息，并根据该第一测量信息确定RAN1是否出现故障。In other embodiments, the RAN2 may receive the first measurement information from the UE, and determine whether the RAN1 is faulty according to the first measurement information.

例如，RAN1发送参考信息，该参考信息可以为CSI-RS，CSI-IM，解调参考信号(demodulation reference signal，DMRS)，小区参考信号(cell reference signal，CRS)中的一个或多个。UE接收RAN1发送的参考信息，并进行测量，测量后可以根据RAN1的配置进行周期性或者基于事件进行上报。RAN2和RAN1是同频同配置因此可以接收到UE上报的测量结果，RAN2根据UE上报的测量值，若低于某一阈值，则判断RAN1 出现故障。RAN2可以根据至少一个UE的上报结果进行判定。具体的UE若是根据事件触发上报，则可以设置第二阈值，当测量结果低于该值时进行上报。则RAN2可根据至少一个UE上报结果进行判断RAN1故障。例如，以第一参考信息为CSI-RS为例。RAN2接收到来自UE1和UE2反馈的CSI-RS测量结果小于第二阈值时，则认为UE1和RAN1之间的通信出现问题，即RAN1出现故障。For example, RAN1 sends reference information, and the reference information may be one or more of CSI-RS, CSI-IM, demodulation reference signal (DMRS), and cell reference signal (CRS). The UE receives the reference information sent by the RAN1, and performs measurement. After the measurement, the UE may perform periodic reporting according to the configuration of the RAN1 or report based on an event. RAN2 and RAN1 are in the same frequency and configuration, so they can receive the measurement results reported by the UE. RAN2 judges that RAN1 is faulty if the measurement value reported by the UE is lower than a certain threshold. RAN2 may make the determination according to the reporting result of at least one UE. If the specific UE triggers the report according to an event, a second threshold may be set, and the report will be performed when the measurement result is lower than the value. Then RAN2 can judge the failure of RAN1 according to the result reported by at least one UE. For example, take the first reference information as CSI-RS as an example. When the CSI-RS measurement result fed back by RAN2 from UE1 and UE2 is smaller than the second threshold, it is considered that there is a problem in the communication between UE1 and RAN1, that is, RAN1 is faulty.

在另一些实施例中，RAN2可以接收来自RAN1的第二参考信息，并根据该第二参考信息，确定RAN1是否出现故障。示例性的，类似于上述说明，RAN2可以根据对第二参考信号进行测量，若测量结果低于第三阈值，则确定RAN1出现故障。所述第二参考信息与第一参考信息可以相同。RAN2可以根据RAN1发送的对第二参考信息的配置，进而进行测量。In other embodiments, RAN2 may receive second reference information from RAN1, and determine whether RAN1 is faulty according to the second reference information. Exemplarily, similar to the above description, the RAN2 may measure the second reference signal, and if the measurement result is lower than the third threshold, it is determined that the RAN1 is faulty. The second reference information may be the same as the first reference information. RAN2 may perform measurement according to the configuration of the second reference information sent by RAN1.

需要说明的是，在实际执行过程中，RAN2可以灵活采取上述示例中提供的一种或多种方法判断RAN1是否出现故障。本申请实施例对此不作限制。It should be noted that, in the actual execution process, the RAN2 may flexibly adopt one or more methods provided in the above example to determine whether the RAN1 is faulty. This embodiment of the present application does not limit this.

在RAN2确定RAN1出现故障后，就可以接管RAN1与UE1之间的通信。当UPF确定RAN1数据不可达后，则停止向RAN1传输数据。待到RAN1故障解除恢复工作后，由RAN2将RAN1地址再发送给UPF，或者通知UPF该路径可达时，则UPF即可向RAN1发送数据，恢复双路传输。RAN1与RAN2互为备份关系，且故障恢复后可以维持当前工作状态或者转换为RAN1工作RAN2备份的状态，需要RAN1和RAN2协商，比如可以协商一个时间点RAN1接管RAN2停止工作，也可以RAN1向RAN2发送接管指示，RAN2停止工作，RAN1继续工作。After RAN2 determines that RAN1 is faulty, it can take over the communication between RAN1 and UE1. When the UPF determines that RAN1 data is unreachable, it stops transmitting data to RAN1. After RAN1 recovers from the fault, RAN2 will send the RAN1 address to UPF again, or notify UPF that the path is reachable, then UPF can send data to RAN1 to resume dual transmission. RAN1 and RAN2 are in a backup relationship with each other, and can maintain the current working state or switch to the backup state of RAN1 working RAN2 after failure recovery. It needs to negotiate between RAN1 and RAN2. Send a takeover instruction, RAN2 stops working, and RAN1 continues working.

示例性的，RAN2可以向RAN1发送接管指示，用于指示RAN1停止工作。同时RAN2可以向AMF发送相应的指示(如第三指示信息)，以便AMF确定RAN2处于非激活或者挂起状态改为激活或非挂起状态，通过地址2向AMF进行信令的下发。由此即实现了RAN2对于RAN1工作的接管。Exemplarily, RAN2 may send a takeover instruction to RAN1 to instruct RAN1 to stop working. At the same time, RAN2 may send a corresponding indication (such as third indication information) to AMF, so that AMF determines that RAN2 is inactive or suspended state is changed to active or non-suspended state, and sends signaling to AMF through address 2. In this way, RAN2 takes over the work of RAN1.

需要说明的是，在一些实施例中，当RAN1为故障时，如果RAN2关闭了或者停止了下行传输，则在确定RAN1故障后，RAN2可以开启该下行传输，以便能够对UE发送的信息进行正确的相应，保证通信的顺利进行。It should be noted that, in some embodiments, when RAN1 is faulty, if RAN2 turns off or stops downlink transmission, after determining that RAN1 is faulty, RAN2 can start the downlink transmission, so that the information sent by the UE can be correctly performed. to ensure smooth communication.
