[0060] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0061] Figure 1 It is one of the flow diagrams of a data processing method provided by the present invention. The present invention discloses a data processing method, the execution subject is a user plane function UPF, including:

[0062] Determine an execution mode of a user plane function UPF, wherein the execution mode includes a dual-transmission mode and a screening mode;

[0063] In the dual-send mode, a first network identifier of a first source data packet and a second network identifier of a first duplicate data packet are respectively marked with a sequence number, so as to send the first source data packet marked with the sequence number and the first duplicate data packet marked with the sequence number to a target terminal;

[0064] In the screening mode, the second source data packet and the second duplicate data packet in the uplink data are respectively parsed to screen out a target data packet in any first data packet set, wherein the sequence number of the target data packet is the sequence number parsed for the first time;

[0065] The first duplicate data packet is determined by duplicating a first source data packet in a user plane function UPF;

[0066] The first network identifier and the second network identifier are determined according to a tunnel of a virtual extended local area network VXLAN;

[0067] The first data packet set is a set of each second source data packet and a second copy data packet corresponding to each second source data packet.

[0068] In step 101, the user plane function (UPF) is an important part of the 5G core network system architecture, and is mainly responsible for the routing and forwarding related functions of the user plane data packets in the 5G core network. As the user plane network element of the 5G network, the user plane function mainly supports the routing and forwarding of terminal service data, data and service identification, action and policy execution, etc., and the present invention can implement the execution modes of the dual-transmission mode and the screening mode according to the user plane function UPF. In the dual-transmission mode, the data packets are mainly copied and sent through multiple channels, while in the screening mode, the received data are screened and recorded, and duplicate data packets are removed.

[0069] In step 102, in the dual-send mode, the first copied data packet is determined by the first source data packet in the copied user plane function UPF, and the first network identifier and the second network identifier are determined according to the tunnel of the virtual extended local area network VXLAN. The present invention adopts the tunnel method of the virtual extended local area network VXLAN to perform dual-send encapsulation of data, and adopts the method of sequence number (SequenceNUM, SN) identification to mark the first network identifier of the first source data packet and the second network identifier of the first copied data packet in turn. At this time, for the data packet set composed of the first copied data packet corresponding to each first source data packet, the same sequence number is used, and for different data packet sets, different sequence numbers are used.

[0070] The present invention uses serial numbers to mark the first network identifier of the first source data packet and the second network identifier of the first copy data packet respectively, and sends the first source data packet marked with the serial number and the first copy data packet marked with the serial number to the target terminal according to the user plane function UPF.

[0071] In step 103, in the screening mode, the uplink data is an uplink data packet sent by the target terminal to the user plane function UPF, and the uplink data packet includes a second source data packet and a second copy data packet, and the second copy data packet is determined by copying the second source data packet. Accordingly, according to the technical solution of marking the data packets with serial numbers in step 102, in this step 103, the second source data packet and the second copy data packet also carry corresponding serial numbers, and this operation step will be completed before the target terminal sends the uplink data to the user plane function UPF.

[0072] Furthermore, the second source data packet and the second copy data packet in the uplink data are parsed respectively to parse out the sequence number of each second source data packet and the sequence number of each second copy data packet. When it is determined that the sequence number of one of the data packets in any first data packet set is an unparsed sequence number, it is considered that the sequence number is a new sequence number that has not been marked. At this time, the data packet corresponding to it is a non-duplicate data packet, and the data packet is filtered out. The first data packet set is a set of each second source data packet and the second copy data packet corresponding to each second source data packet, and then the remaining data packets in the first data packet set are eliminated. The remaining data packets are the data packets in the first data packet set excluding the filtered data packets.

[0073] The present invention provides a data processing method, system, device and medium, which first determine the corresponding execution mode of the user plane function UPF according to different trigger conditions, and implement operations such as dual transmission, analysis, and deduplication of data in different execution modes. The present invention copies and marks the data to be transmitted at the transmitting end, and transmits it at the wireless air interface in a multi-channel manner, so that the received data can be deduplicated at the corresponding receiving end according to the mark, thereby effectively reducing the packet loss rate, delay and jitter without changing the user facilities, and improving the reliability of data transmission at the air interface.

[0074] Figure 2 It is a schematic diagram of a flow chart of determining an execution mode of a user plane function UPF provided by the present invention, wherein determining the execution mode of the user plane function UPF includes:

[0075] In case that the user plane function UPF receives downlink data from the data network DN, determining that the execution mode is a dual-transmission mode;

[0076] In case that the user plane function UPF receives uplink data from the target terminal, it is determined that the execution mode is a screening mode.

[0077] In step 1011, Fig. 9 This is the third structural diagram of a data processing system provided by the present invention. When the user plane function UPF receives downlink data from a data network (DN), the user plane function UPF needs to transmit the downlink data from the data network DN to the target terminal. Accordingly, the downlink data from the data network DN needs to be sent to the target terminal after the dual-send encapsulation operation in step 102, that is, the execution mode is determined to be the dual-send mode.

[0078] In step 1012, when the user plane function UPF receives uplink data from the target terminal, that is, the target terminal double-encapsulates the uplink data and transmits it to the user plane function UPF, at this time, it is necessary to parse and deduplicate the uplink data received from the target terminal, that is, determine that the execution mode is the screening mode.

[0079] Figure 3 The present invention provides a flow chart of sending a first source data packet and a first copy data packet to a target terminal, wherein the first network identifier of the first source data packet and the second network identifier of the first copy data packet are respectively marked with a sequence number, so as to send the first source data packet marked with the sequence number and the first copy data packet marked with the sequence number to the target terminal, including:

[0080] Mark each first source data packet with a different sequence number in the network identifier VNI of the virtual extended local area network VXLAN tunnel;

[0081] Marking the first duplicate data packet corresponding to each first source data packet according to the sequence number corresponding to each first source data packet;

[0082] Each first source data packet is sent to the target terminal using a first channel path, and each first copy data packet is sent to the target terminal using a second channel path.

[0083] In step 1021, when the user plane function UPF sends the downlink data received from the data network DN to the target terminal in two paths, the serial number is used to add an identification serial number to the first source data packet at the end of the network identifier VNI of the virtual extended local area network VXLAN tunnel header.

[0084] In step 1022, since there is an identical copy data packet for each first source data packet, that is, for each first source data packet, the first copy data packet corresponding to each first source data packet is marked according to the serial number corresponding to each first source data packet, so that the serial number is used to add the same identification serial number to the same source data packet at the end of the network identifier VNI of the virtual extended local area network VXLAN tunnel header.

[0085] In step 1023, each first source data packet is sent to the target terminal using the first channel path, and each first copy data packet is sent to the target terminal using the second channel path. The present invention uses an independent channel path (Path Session) for each first source data packet and an independent channel path (Path Session) for each second source data packet, so that the present invention can forward the data packets to the target terminal in a multi-channel and multi-session manner, so that it has high reliability at the wireless air interface.

[0086] Figure 4 The present invention provides a flow chart of respectively parsing a second source data packet and a second copy data packet in uplink data, wherein the process of respectively parsing a second source data packet and a second copy data packet in uplink data includes:

[0087] Receiving a second source data packet of a third channel path and a second copy data packet of a fourth channel path respectively;

[0088] Parse the second source data packet and the second copy data packet to obtain a serial number corresponding to each second source data packet and a serial number corresponding to each second copy data packet.

[0089] In step 1031, in such an embodiment, the target terminal adopts a multi-channel form to transmit the second source data packet and the second copy data packet after double encapsulation to the user plane function UPF using different channel paths respectively, and the user plane function UPF respectively receives the second source data packet of the third channel path and the second copy data packet of the fourth channel path.

[0090] In step 1032, each second source data packet has an identical second copy data packet, and the two constitute a second data packet group. Before being sent by the target terminal, each second data packet group is marked with the same serial number so that different second data packet groups have different serial numbers. The second source data packet and the second copy data packet are parsed to obtain the serial number corresponding to each second source data packet and the serial number corresponding to each second copy data packet.

[0091] Figure 5 This is the second flow chart of a data processing method provided by the present invention. The present invention also discloses a data processing method, the execution subject is a target terminal, and includes:

[0092] Determine an execution mode of the target terminal, wherein the execution mode includes a dual-send mode and a screening mode;

[0093] In the dual-transmission mode, the third network identifier of the third source data packet and the fourth network identifier of the third duplicate data packet are respectively marked with a sequence number, so as to send the third source data packet marked with the sequence number and the third duplicate data packet marked with the sequence number to the user plane function UPF;

[0096] The third network identifier and the fourth network identifier are determined according to a tunnel of a virtual extended local area network VXLAN;

[0097] The second data packet set is a set of each fourth source data packet and a fourth copy data packet corresponding to each fourth source data packet.

[0098] In step 201, the target terminal is an important part of the 5G core network system architecture. The current 5G network is networked according to the core network, base station, target terminal, and transmission equipment. After the target terminal accesses the base station, the data is sent from the air interface to the base station, and the base station sends it to the user plane function UPF of the core network through the transmission equipment. The user plane function UPF processes and forwards it to the external network. The present invention can implement the execution mode of the dual-transmission mode and the screening mode according to the target terminal. In the dual-transmission mode, the data packet is mainly copied and sent through multiple channels, while in the screening mode, the received data is screened and recorded, and duplicate data packets are removed.

[0099] In step 202, in the dual-send mode, the third replicated data packet is determined by the third source data packet in the replication target terminal, and the third network identifier and the fourth network identifier are determined according to the tunnel of the virtual extended local area network VXLAN. The present invention adopts the tunnel mode of the virtual extended local area network VXLAN to perform dual-send encapsulation of data, and adopts the sequence number (SequenceNUM, SN) identification mode to mark the third network identifier of the third source data packet and the fourth network identifier of the third replicated data packet in turn. At this time, the second data packet set is a set of each fourth source data packet and the fourth replicated data packet corresponding to each fourth source data packet. For the second data packet set composed of the third replicated data packet corresponding to each third source data packet, the same sequence number is used, and for different second data packet sets, different sequence numbers are used.

[0100] The present invention uses serial numbers to mark the third network identifier of the third source data packet and the fourth network identifier of the third copy data packet respectively, and sends the third source data packet marked with the serial number and the third copy data packet marked with the serial number to the user plane function UPF according to the target terminal.

[0101] In step 203, in the screening mode, the fourth source data packet and the fourth copy data packet in the downlink data from the user plane function UPF are parsed respectively, the downlink data packet is a downlink data packet sent by the user plane function UPF to the target terminal, the downlink data packet includes a fourth source data packet and a fourth copy data packet, the fourth copy data packet is determined by copying the fourth source data packet, accordingly, according to the technical solution of marking the data packets with serial numbers in step 102, in this step 203, the fourth source data packet and the fourth copy data packet also carry corresponding serial numbers, and this operation step will be completed before the downlink data packet sent by the user plane function UPF to the target terminal.

[0104] When the target terminal receives downlink data sent from a user plane function UPF, it is determined that the execution mode is a screening mode.

[0105] In step 2011, the input instruction may include a third source data packet for executing the dual-send mode, and at the same time have an input signal that needs to be sent to the user plane function UPF. Furthermore, when the target terminal receives the input instruction, it is considered that it needs to adopt the dual-send mode to dual-encapsulate the third source data packet and then send it to the user plane function UPF.

[0106] In step 2012, when the target terminal receives downlink data sent from the user plane function UPF, that is, the user plane function UPF encapsulates the downlink data in dual transmission and transmits it to the target terminal, at this time, it is necessary to parse and deduplicate the downlink data received from the user plane function UPF, that is, determine that the execution mode is the screening mode.
