[0002] With the widespread application of 5G mobile networks, more and more scenarios require multimodal service flow coordination to complete tasks. In multimodal service scenarios, when multiple modalities (audio, video, control signaling, motion data, etc.) exist within the same service, to meet the actual service requirements, these multiple service flows need to maintain a certain level of synchronization. That is, the relative order of different service flows originating from different source terminals should remain unchanged after arriving at different destination terminals. Therefore, a method for synchronizing multiple service flows is needed. Summary of the Invention

[0065] The present invention will be further described in detail below with reference to the embodiments, starting with a description of the relevant technologies.

[0066] As mentioned above, the relative order of different service flows originating from different source terminals needs to remain unchanged upon arrival at different destination terminals. The following solutions are provided in related technologies:

[0067] For situations where different service flows (voice, video, control signaling, etc.) originate from the same source terminal and arrive at the same destination terminal, the source terminal and destination terminal can use a unified encoding method for different service data to achieve coordination of different service data, or add design task frames and system frame numbers to achieve coordination of multiple service flows on the same terminal.

[0068] For multi-service packets that need to be coordinated from different source terminals to different destination terminals, there is also a design controller to obtain the transmission status of the data streams that need to be synchronized and generate transmission adjustment information for the network intermediate nodes corresponding to the data streams based on the transmission status. The controller sends the transmission adjustment information to the network intermediate nodes to realize the synchronization of multiple data streams that need to be synchronized on the network side.

[0069] However, the above solutions either rely on the end-side processing system to correlate and synchronize packets from different service flows, or on a network-side super controller capable of dynamically adjusting network parameters for different service flows that need synchronization. Specifically, the following issues arise:

[0070] Question 1: In the current 5G mobile network system, the service flows that need to be coordinated belong to different application devices, making it impossible to complete the coordinated processing of service flows using a unified terminal. For example, in a factory remote demonstration case... Figure 1 As shown:

[0071] At the sending end (factory), two signals are transmitted: 1) collection of robot control information; 2) video collection of robot behavior;

[0072] At the receiving end (demonstration site), the two signals are used for: 1) converting robot control information signals into the behavior of the virtual robot in VR; 2) playing the captured video on the screen.

[0073] The two applications are developed by different manufacturers and run on completely different hardware. Therefore, it is impossible to develop a terminal that can coordinate the two applications to complete the coordination of the two business flows and ensure that the sequence of the two business flows arriving at the destination remains unchanged from the sequence sent out by the source.

[0074] Question 2: During the process of transmitting business data using the 5G mobile network, there are many network devices involved. It is not possible to open the configuration interfaces of all network devices along the mobile network path to collect the transmission status of different business data and adjust the corresponding transmission data.

[0075] To address the aforementioned issues, there is a need for a solution that addresses the multi-service flow coordination requirements from different sources and destinations while minimizing disruption to 5G mobile network architecture and configuration.

[0076] Here, we will further combine Figure 2 Explain the data transmission schemes in the relevant technologies;

[0077] Figure 2 This is a schematic diagram of a data transmission network structure provided in an embodiment of the present invention; as shown below. Figure 2As shown, the data source of the collaborative data service group is connected to the network via the same Customer Premise Equipment (CPE), and the data destination of the collaborative data service group is connected to the network via the same CPE.

[0078] The message sequence sent by terminal (UE) A is processed by SNAT in sequence at the source CPE (denoted as CPE1) and then sent to the source base station (denoted as gNB1) to enter the mobile network; when it finally reaches the terminal CPE (denoted as CPE2), CPE2 performs SNAT reverse processing on the message and then sends it to UEC.

[0079] The message sequence sent by the UEB is processed by SNAT in sequence at the source CPE (i.e., CPE1) and then sent to the source base station (i.e., gNB1) to enter the mobile network; when it finally reaches the end CPE (i.e., CPE2), CPE2 performs SNAT reverse processing on the message and then sends it to the UED.

[0080] Because each message sequence is forwarded on the network according to the "best-effort" principle, the arrival time and order of different messages at the endpoint cannot be guaranteed. Figure 3 As shown.

[0081] Based on this, the method provided in this embodiment of the invention involves a first network device determining at least two service packets that meet preset conditions, generating a group packet based on the at least two service packets, and sending the group packet to a second network device. The group packet is then split by the second network device and sent to the corresponding terminal. Correspondingly, the second network device receives the group packet from the first network device, splits the group packet to obtain at least two service packets, and sends each of the at least two service packets to the corresponding terminal.

[0082] The present invention will be further described in detail below with reference to the embodiments.

[0083] Figure 4 This is a flowchart illustrating a data transmission method provided in an embodiment of the present invention; as shown below. Figure 4 As shown, the method is applied to a first network device; the first network device can be a CPE, denoted as the first CPE, specifically a source-side CPE; the method includes:

[0084] Step 401: Determine at least two service messages that meet preset conditions, and generate a group message based on the at least two service messages;

[0085] Step 402: Send the group message to the second network device; the group message is split by the second network device and sent to the corresponding terminal.

[0086] In some embodiments, determining at least two service messages that satisfy preset conditions includes:

[0087] Determine the address information of each of at least two pending service messages; the address information specifically includes: source address information and destination address information;

[0088] Based on the address information of each of the pending service messages, a preset matching rule is queried to determine at least two service messages that meet the preset conditions;

[0089] The preset matching rules include: at least one set of matching addresses.

[0090] The destination address information refers to the address information of the destination terminal to which the service message is to be sent; the specific address is determined based on the actual sending requirements; the source address information refers to the address information of the terminal that sends the service message.

[0091] Here, the service message to be processed can be a service message of multiple modes (also known as a service flow), such as audio, video, control signaling, action data and other service messages.

[0092] Specifically, the preset matching rules are used to indicate at least two service messages (i.e., service data streams) that can be matched.

[0093] In practical applications, users (such as operations and maintenance personnel) can configure the matching addresses and save them in the matching rules.

[0094] Here, the matching addresses can be: at least two sets of source and destination address relationships; for example, UE1 sending to UE3 and UE2 sending to UE4 are pre-configured as a pair of matching addresses; in application, it can be assumed that service packets sent from UE1 to UE3 and service packets sent from UE2 to UE4 can be packaged into group packets.

[0095] The address matching relationship between UE1 sending to UE3 and UE2 sending to UE4 can be stored in the matching rules according to the number of each UE and the address corresponding to each UE. In practical applications, the matching rules are queried based on the address of the UE that needs to send the service message (i.e., the source address information) and the address of the UE to which it is to be sent (i.e., the destination address information). When a match is found with the matching rules, it is considered that there are at least two service messages that can be packaged into a group message.

[0096] The address information can be Internet Protocol (IP) address, Media Access Control (MAC) address, etc.

[0097] In some embodiments, before generating the group message based on the at least two service messages, the method further includes:

[0098] Perform a Network Address Translation (NAT) operation on each of the at least two service packets to obtain the source address information of each service packet after translation.

[0099] In some embodiments, generating a group message based on the at least two service messages includes:

[0100] The at least two service messages are reassembled to obtain at least one storage segment;

[0101] The message is encapsulated based on the at least one segment of the storage to obtain a group message;

[0102] Wherein, each of the at least one storage units includes at least one of the following: message type, message length, and message.

[0103] Here, the storage body adopts the Type-Length-Value (TLV) format; wherein, the type can store the message type stored in the storage body, the length can store the message length of the message stored in the storage body, and the Internet Protocol (IP) packet can store the corresponding message;

[0104] The message may include: message content and message address information, wherein the address information includes: destination address information of the message and source address information of the converted message.

[0105] In this way, after the second network device receives and splits the packet, it can determine the destination address information corresponding to the corresponding service packet, i.e. the address information of the destination terminal, based on the address information of each storage segment. Thus, the service packet is distributed based on the destination address information to complete the data transmission.

[0106] Here, the group message uses one or more storage units to store the data message. That is, the group message can include at least one storage unit. Each storage unit is used to store one segment of the reassembled data message from at least two service messages. The destination address corresponding to each data message segment is recorded in the IP packet so that the CPE at the destination end can split and distribute the data to the corresponding destination terminal.

[0107] Considering that all service messages that need to be synchronized are packaged in the same group message and transmitted in the mobile / fixed network as a group message, it can be ensured that when the destination CPE receives this group message, the IP protocol stack on the CPE can be effectively utilized to achieve the order preservation and reassembly of the group message, and the relative order of all service messages packaged in the message remains consistent with that when sent from the source after splitting.

[0108] Thus, the sequence of two service messages arriving at the destination remains unchanged from the sequence sent from the source.

[0109] In some embodiments, sending the group message to the second network device includes:

[0110] The mobile address of the first network device is used as the source address of the group message, and the group message is sent to the second network device according to a preset group message time interval;

[0111] The preset group message time interval is determined based on the message transmission frequency requirements. These requirements are set by developers or users based on their needs.

[0112] Figure 5 A flowchart illustrating another data transmission method provided in an embodiment of the present invention; as shown Figure 5 As shown, the method is applied to a second network device; the second network device can be a CPE, denoted as the second CPE, specifically a destination-side CPE; the method includes:

[0113] Step 501: Receive a group message from the first network device;

[0114] Step 502: Split the group of packets to obtain at least two service packets;

[0115] Step 503: Send each of the at least two service messages to the corresponding terminal.

[0116] In some embodiments, before splitting the group of packets, the method further includes:

[0117] Order preservation processing is performed based on at least one group of received messages.

[0118] Here, considering that all service messages that need to be synchronized are packaged in the same group message and transmitted in the mobile / fixed network as a group message, it can be ensured that when the destination CPE receives this group message, the IP protocol stack on the CPE can be effectively utilized to achieve the order preservation and reassembly of the group message, and the relative order of all service messages packaged in the message remains consistent with that when sent from the source after splitting.

[0119] Specifically, during group message transmission, the group message may be too long (exceeding the network's length requirement) and therefore sent in fragments. Different fragments may arrive in different orders due to network reasons, meaning that the fragments may not arrive at the destination in the order they were sent. Therefore, after receiving the fragments, the destination can buffer them and reassemble them into a complete group message, that is, package them together as a reassembled IP packet, and then unpack them according to the reassembled group message. This achieves the order preservation and reassembly of the group message.

[0120] In some embodiments, sending each of the at least two service messages to the corresponding terminal includes:

[0121] Perform a reverse Network Address Translation (NAT) operation on each of the service packets to determine the destination address information corresponding to each service packet, that is, the address information of the destination terminal corresponding to each service packet;

[0122] Each service message is sent to the corresponding destination terminal based on the address information of the destination terminal corresponding to each service message.

[0123] pass Figure 4 and Figure 5 The data transmission method described above, after completing the NAT address translation of the original packets on the source CPE side (i.e., the first network device, or the first CPE), periodically reassembles the multi-flow service packets to be coordinated, and sends the reassembled group packets with the address of the first CPE as the source address. Upon receiving the coordinated group packets on the destination CPE side (i.e., the second network device, or the second CPE), the group packets are split into individual service packets, and the split service packets are sequentially processed by NAT reversal before being distributed. Thus, through the above-described multi-service service packet coordinated transmission method, service flow alignment and synchronization are achieved, ensuring the consistency of multiple service flows, i.e., coordinated service flow transmission is realized.

[0124] The first CPE and the second CPE can specifically be 5G CPE, that is, CPE that supports 5G network. It can receive 5G network signals like a 5G mobile phone and convert them into WiFi signals. It has advantages such as mobility, strong access and good signal. It can be used to build small-scale experimental / display networking and demonstration networking for many industrial Internet applications.

[0125] In a scenario where data is sent from a first CPE to a second CPE, the first CPE can perform the following functions:

[0126] 1. Configurable matching rules for multimodal service messages and automatic allocation of group numbers for group messages;

[0127] 2. The time interval for sending group messages can be preset according to local time and message sending frequency requirements;

[0128] 3. For CPE mobile addresses, perform NAT processing on all service packets sequentially;

[0129] 4. Within the same time interval, group packets are encapsulated for multimodal service messages that require data coordination, and the group packets are sent to the base station using the CPE mobile address as the source address.

[0130] The second CPE can perform the following functions:

[0131] 1. Receive group messages (i.e., the local machine) from the base station and perform order preservation processing;

[0132] 2. Identify group messages and perform service message splitting within the group messages;

[0133] 3. Perform SNAT reverse processing on the split service flows and distribute them to different destination terminals.

[0134] In scenarios where data is returned from the second CPE to the first CPE, the second CPE, acting as the sender, can also perform the functions described above for the first CPE, i.e., execute... Figure 4 The method shown; the first CPE, acting as the receiving end (i.e., the destination end), can also achieve the same function as the second CPE, i.e., execute... Figure 5 The method shown.

[0135] Figure 6 A schematic diagram of a data transmission network provided for an application embodiment of the present invention; as shown. Figure 6 The CPE on the data source side is modified to reassemble all business messages that need to be coordinated (i.e., business messages that meet the preset conditions) according to a specified granularity (e.g., time interval) to obtain coordinated group messages (referred to as group messages); correspondingly, the CPE on the data destination side is modified to split and distribute the received business messages.

[0136] Because all service messages requiring synchronization are packaged in the same group message and transmitted in mobile / fixed networks as group messages, it can be ensured that when the destination CPE receives this group message, the IP protocol stack on the CPE can be effectively utilized to achieve message ordering and reassembly. Furthermore, the relative order of all service messages packaged in the group message remains consistent with the order in which they were sent from the source after splitting. Figure 7 As shown.

[0137] Figure 8 This is a schematic diagram of a group message encapsulation provided in an embodiment of the present invention; as shown. Figure 8As shown, the Media Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP), and Service Discovery Application Profile (SDAP) are defined protocol messages between the CPE and the base station. The CPE reassembles the group messages and encapsulates them according to the collaborative group protocol (CGP) message format.

[0138] Among them, the CGP protocol is the group message co-encapsulation protocol required by the method provided in the embodiments of the present invention; CGP can be regarded as an application layer protocol based on the UDP protocol, and the port number is 38899.

[0139] For group messages in CGP protocol format, the message header includes:

[0140] GroupId: 8 bits, stores the group ID of the group message;

[0141] Length: 8 bits, stores the total length of the group message, including the group ID length of the group message;

[0142] PktNum: 8 bits, stores the number of packets in the group message;

[0143] The message portion uses a TLV format storage device;

[0144] TLV: Collaborative service group messages stored in the format of type, length, and value; specifically, T(8) stores the message type, L(8) stores the message length, and IP Packet stores the specific message content and message address information.

[0145] The total number of TLVs is determined by PktNum (packet value), which is based on the number of storage segments required for the reassembled group messages.

[0147] The first processing module is used to determine at least two service messages that meet preset conditions, and generate a group message based on the at least two service messages;

[0157] The preset group message time interval is determined according to the message sending frequency requirements.
