[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure claims priority to Chinese patent application number 202310877022.5, filed on July 17, 2023, entitled “Data Transmitting Method, Device, Electronic Device and Computer-Readable Storage Medium”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to the field of communication technologies, and in particular to a data sending method, device, electronic device, computer-readable storage medium, and computer program product. Background Art

[0004] In the field of communications technology, 5G (5th Generation Mobile Communication Technology) mobile communication networks have introduced various deterministic technologies to better support the needs of URLLC (Ultra-Reliable Low-Latency Communications) services. One deterministic technology utilizes a dual-transmit selective data transmission and reception method to ensure determinism and low latency during data transmission.

[0005] In related technologies, the dual-send selective reception function is deployed at both ends of a communication, where the two ends of the communication include a terminal and a server accessed by the terminal.

[0006] However, deploying the dual-transmit selective reception function at both ends of communication requires the terminals to have the ability to implement the dual-transmit selective reception function. However, the cost of iterating the terminals to enable the terminals to have the ability to implement the dual-transmit selective reception function is high, making the deterministic technology of dual-transmit selective reception difficult to implement.

[0007] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

[0051] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, they should be understood as "one or more".

[0052] FIG1 shows a schematic diagram of a data sending system in an embodiment of the present disclosure, to which the data sending method or data sending apparatus in various embodiments of the present disclosure can be applied.

[0053] As shown in FIG1 , the data transmission system may include: multiple terminals 101 , a gateway 102 , multiple base stations, a UPF (User Plane Function) network element 104 , and an application server 105 .

[0054] The gateway 102 is configured with at least one communication module pair, each communication module pair including two communication modules. It should be noted that the communication module 1021 and the communication module 1022 shown in FIG1 belong to the same module pair.

[0055] Each communication module configured in the gateway 102 can establish an Ethernet PDU (Protocol Data Unit) session with the UPF network element 104. The gateway 102 can send data to the UPF network element 104 based on the Ethernet PDU session between the communication module and the UPF network element 104, and can also receive data sent by the UPF network element 104 based on the PDU session.

[0056] Gateway 102 can also receive uplink data sent by any of multiple terminals 101 and forward the uplink data based on the destination address of the uplink data. In one embodiment, gateway 102 can copy the received uplink data, encapsulate the original uplink data and the copied uplink data with the same first tag, and then send the two copies of uplink data to UPF network element 104 based on the Ethernet PDU sessions of the two communication modules belonging to the same communication module pair. One PDU session corresponds to one copy of uplink data.

[0057] For example, the Ethernet PDU session path between communication module 1021 and UPF network element 104 includes base station 1031 among multiple base stations, the Ethernet PDU session path between communication module 1022 and UPF network element 104 includes base station 1032 among multiple base stations, and gateway 102 forwards two copies of uplink data with the same first tag to UPF network element 104 based on the Ethernet PDU sessions between communication modules 1021 and 1022. The forwarding path for one copy of the uplink data to UPF network element 104 is: communication module 1021 - base station 1031 - UPF network element 104. The forwarding path for the other copy of the uplink data to UPF network element 104 is: communication module 1022 - base station 1032 - UPF network element 104.

[0058] It should be noted that the path of the Ethernet PDU session between two communication modules belonging to the same communication module pair and the UPF network element 104 may include the same base station.

[0059] The UPF network element 104 selects and forwards the two uplink data based on the first label. Taking the destination address of the uplink data indicating the application server 105 as an example, the UPF network element 104 forwards the uplink data to the application server 105.

[0060] The process of the UPF network element 104 selecting and forwarding the two uplink data based on the first label includes: after receiving the uplink data that arrives earlier of the two uplink data, the UPF network element 104 sends an ACK (ACKnowledge Character) to the gateway 102 to indicate receipt of the uplink data, and forwards the earlier-arrived uplink data to the application server 105. Thereafter, after receiving the other uplink data, the UPF network element 104 determines that the other uplink data is duplicated data based on the first label, discards the other uplink data, and performs other processing other than forwarding, thereby completing deduplication and forwarding of the two uplink data.

[0061] In one embodiment, the gateway 102 may determine whether to replicate the uplink data based on the port of the source address and / or the port of the destination address of the uplink data. If it is determined that the uplink data does not need to be replicated for multiple transmissions, the gateway 102 may send the uplink data to the UPF network element 104 via an Ethernet PDU session of any communication module.

[0062] In one embodiment, the UPF network element 104 stores the correspondence between the two communication modules of each communication module pair configured in the gateway 102. The embodiments of the present disclosure do not limit how to store the correspondence in the UPF network element.

[0063] In one embodiment, the corresponding relationship can be configured in the UPF network element 104 by static writing.

[0064] In another embodiment, the corresponding relationship may be pre-configured in a UDM (Unified Data Management) network element, and then the UDM network element sends the corresponding relationship to the UPF network element 104 .

[0065] In another embodiment, the UPF network element 104 can replicate the downlink data sent by the application server 105 and encapsulate the original downlink data and the replicated downlink data with the same second tag. The UPF network element 104 then uses the stored correspondence to identify the two communication modules that belong to the same communication module pair. The two copies of downlink data are then sent to the gateway 102 based on the Ethernet PDU sessions of the two communication modules in the same communication module pair. One PDU session corresponds to one copy of the downlink data.

[0066] Continuing with the example, the path of the Ethernet PDU session between communication module 1021 and UPF network element 104 includes base station 1031 among multiple base stations, the path of the Ethernet PDU session between communication module 1022 and UPF network element 104 includes base station 1032 among multiple base stations, and UPF network element 104 forwards two copies of downlink data with the same second tag to gateway 102 based on the Ethernet PDU sessions between communication modules 1021 and 1022. The forwarding path for one copy of downlink data to gateway 102 is: UPF network element 104 - base station 1031 - communication module 1021. The forwarding path for the other copy of downlink data to gateway 102 is: UPF network element 104 - base station 1032 - communication module 1022.

[0067] The gateway 102 selects and forwards the two downlink data based on the second tag. For example, if the destination address of the downlink data indicates one of the multiple terminals 101 , the gateway 102 forwards the downlink data to the terminal.

[0068] The process by which gateway 102 selects and forwards the two downlink data packets based on the second tag includes: upon receiving the first of the two downlink data packets, gateway 102 sends an ACK to UPF network element 104 to indicate receipt of the downlink data, and then forwards the first-arrived downlink data packet to the corresponding terminal. Subsequently, upon receiving the other downlink data packet, gateway 102 determines based on the second tag that the other downlink data packet is duplicate data, discards the other downlink data packet, or otherwise performs other processing other than forwarding the other downlink data packet, thereby completing deduplication and forwarding of the two downlink data packets.

[0069] In one embodiment, the UPF network element 104 may determine whether to replicate the downlink data based on the port of the source address and / or the port of the destination address of the downlink data. If it is determined that the downlink data does not need to be replicated for multiple transmission, the UPF network element 104 may send the downlink data to the gateway 102 via the Ethernet PDU session of any communication module.

[0070] The technical solution provided by the embodiments of the present disclosure realizes a dual-transmission and selective reception method on the network side through the cooperation of the gateway and the UPF network element. Since the correspondence between the gateway, the UPF network element and the terminal is one-to-many, that is, the gateway and the UPF network element both serve multiple terminals, compared with improving the terminal so that the terminal has the dual-transmission and selective reception capability, the method of configuring a communication module pair in the gateway requires lower costs and less workload, thereby reducing the cost of implementing the dual-transmission and selective reception function in the network, which is conducive to promoting the implementation of the dual-transmission and selective reception function in the network, thereby improving the reliability and certainty of data transmission.

[0071] Multiple terminals 101, gateways 102, multiple base stations, UPF network elements 104, and application servers 105 are connected to each other through a network, which can be a wired network or a wireless network.

[0072] In some embodiments, the wireless network or wired network described above uses standard communication technologies and / or protocols. The network is typically the Internet, but may also be any network, including but not limited to a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile, wired or wireless network, a private network or any combination of a virtual private network). In some embodiments, technologies and / or formats including Hypertext Markup Language (HTML), Extensible Markup Language (XML), etc. are used to represent data exchanged over the network. In addition, conventional encryption technologies such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), and Internet Protocol Security (IPsec) may be used to encrypt all or some links. In other embodiments, customized and / or dedicated data communication technologies may be used to replace or supplement the above-mentioned data communication technologies.

[0073] Any of the multiple terminals 101 can be various electronic devices, including but not limited to smart phones, tablet computers, laptop computers, desktop computers, wearable devices, augmented reality devices, virtual reality devices, etc.

[0074] In one embodiment, any one of the multiple terminals 101 is an industrial terminal. The embodiments of the present disclosure do not limit the specific type of industrial terminal.

[0075] In one embodiment, gateway 102 is an industrial gateway.

[0076] The application server 105 may be a server that provides various services, such as a background management server that provides support for devices operated by users using the terminal 101. The background management server may analyze and process received request data and feed back the processing results to the terminal device.

[0077] In some embodiments, the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers. It can also be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms.

[0078] Those skilled in the art will appreciate that the number of terminals, base stations, gateways, UPF network elements, and application servers in FIG1 is merely illustrative, and any number of terminals, base stations, gateways, UPF network elements, and application servers may be used as needed. This disclosure does not limit this.

[0079] This exemplary implementation is described in detail below with reference to the accompanying drawings and examples.

[0080] The present disclosure provides a data transmission method, which can be executed by any electronic device with computing and processing capabilities, for example, a gateway.

[0081] FIG2 shows a flow chart of a data sending method in one embodiment of the present disclosure. As shown in FIG2 , the data sending method provided in the embodiment of the present disclosure includes the following S201 to S203 .

[0082] S201: The gateway receives uplink data sent by the terminal.

[0083] S202: The gateway copies the uplink data and packs the uplink data and the copied uplink data with a first label to obtain two copies of uplink data both having the first label.

[0084] The embodiments of the present disclosure do not limit the specific type of label that the first label is. For example, the first label includes the destination address of the uplink data and the serial number of the uplink data. For another example, the first label includes the source address of the uplink data and the serial number of the uplink data. For another example, the first label includes the source address, destination address, and serial number of the uplink data. For another example, the first label is a label generated by the gateway for the uplink data and is used to uniquely identify the uplink data. The embodiments of the present disclosure do not limit the specific composition of the first label generated by the gateway.

[0085] It should be noted that the two uplink data pieces both having the first tag include the same data content.

[0086] In one embodiment, the gateway stores at least one first port information, and copying the uplink data may include: determining a first relationship between the port information of the destination address of the uplink data and the at least one first port information; when the first relationship is that the at least one first port information includes the port information of the destination address, copying the uplink data.

[0087] Among them, when at least one first port information includes the port information of the destination address of the uplink data, it can be determined that the uplink data is uplink data that needs to be dual-sent (copying and packaging the same first label, and sending it to the UPF network element through the Ethernet PDU session of two modules belonging to the same communication module pair). The first port information is used to compare with the port information of the destination address of the uplink data to determine whether the uplink data needs to be dual-sent.

[0088] In another embodiment, the gateway stores at least one second port information, and copying the uplink data may include: determining a second relationship between the port information of the source address of the uplink data and at least one second port information; when the second relationship is that at least one second port information includes the port information of the source address, copying the uplink data.

[0089] Among them, when at least one second port information includes the port information of the source address of the uplink data, it can be determined that the uplink data is uplink data that needs to be dual-sent, and the second port information is used to compare with the port information of the source address of the uplink data to determine whether the uplink data needs to be dual-sent.

[0090] In another embodiment, the gateway stores at least one first port information and at least one second port information, and copying the uplink data may include: determining a first relationship between the port information of the destination address of the uplink data and the at least one first port information, and a second relationship between the port information of the source address of the uplink data and the at least one second port information; when the first relationship is that the at least one first port information includes the port information of the destination address, and the second relationship is that the at least one second port information includes the port information of the source address, copying the uplink data.

[0092] By utilizing at least one first port information and / or at least one second port information, uplink data can be selectively dual-transmitted, thereby facilitating service for uplink data that needs dual-transmission more and avoiding resource waste caused by dual-transmitting all uplink data.

[0093] S203, the gateway sends one uplink data of the two uplink data to the UPF network element based on the Ethernet PDU sessions of the two communication modules belonging to the same communication module pair, so that the UPF network element forwards the uplink data received first of the two uplink data based on the first label.

[0094] The gateway copies the uplink data, and after packaging the original uplink data and the copied uplink data with the same first label, the two copies of the uplink data are sent to the UPF network element through the Ethernet PDU sessions of the two communication modules belonging to the same communication module pair. Among them, one copy of the uplink data is sent by one Ethernet PDU session. Afterwards, the UPF network element forwards the uplink data received first of the two copies of the uplink data based on the first label, and discards (or performs other processing other than forwarding, for example, only storing it locally) the uplink data received later of the two copies of the uplink data (this process is hereinafter referred to as: selecting and forwarding the two copies of the uplink data based on the first label).

[0095] By sending one of the two copies of uplink data respectively through two Ethernet PDU sessions, the reliability and certainty of the uplink data transmission can be better guaranteed.

[0096] For the specific implementation of the UPF network element selecting and forwarding the two copies of uplink data based on the first label, please refer to the description in the embodiment corresponding to Figure 1, which will not be repeated here.

[0097] In one embodiment, before performing S203, it is necessary to establish an Ethernet PDU session between the communication module in the gateway and the UPF network element, so as to facilitate the subsequent sending or receiving of data based on the Ethernet PDU session.

[0098] It should be noted that the gateway is configured with at least one communication module pair, each communication module pair including two communication modules, each of which can establish an Ethernet PDU session with a UPF network element. The embodiments of this disclosure do not limit the number of at least one communication module pair. For example, at least one communication module pair is one communication module pair.

[0099] In one embodiment, the gateway also receives a copy of downlink data with a second label sent by the UPF network element based on the respective Ethernet PDU sessions of the two communication modules belonging to the same communication module pair, and obtains two copies of downlink data, the data content of the two copies of downlink data is the same; and forwards the downlink data received first of the two copies of downlink data based on the second label (this process is hereinafter referred to as: selecting and forwarding the two copies of downlink data based on the second label).

This method provides a way to implement the deterministic technology of dual transmission and selective reception on the network side. In addition, since the relationship between the gateway and the terminal is one-to-many, that is, the gateway serves multiple terminals, iterating the gateway to enable the gateway to have dual transmission capabilities requires less cost and workload than iterating the terminal to enable the terminal to have dual transmission capabilities, which reduces the cost required for the implementation of the deterministic technology of dual transmission and selective reception, and is conducive to promoting the implementation of the dual transmission and selective reception function.

[0120] S304, the UPF network element sends one of the two downlink data to the gateway based on the Ethernet PDU sessions of the two communication modules belonging to the same communication module pair, so that the gateway forwards the downlink data received first of the two downlink data based on the second label.

[0121] The UPF network element copies the downlink data and encapsulates the original and copied data with the same second tag. It then sends the two copies of the downlink data to the gateway via separate Ethernet PDU sessions for the two communication modules in the same communication module pair. Each copy of the downlink data is sent via a single Ethernet PDU session. The gateway then selects and forwards the two copies of the uplink data based on the second tag.

Subsequently, the gateway selectively receives the dual-sent downlink data. This approach provides a way to implement the deterministic technology of dual transmission and reception on the network side, reducing the cost required to implement this deterministic technology and promoting the implementation of the dual transmission and reception selective function.
