[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments 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.

[0021] The flowcharts shown in the accompanying drawings are only examples and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may also be decomposed, combined or partially merged, so the actual execution order may change according to actual conditions.

[0022] It should be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0023] The embodiment of the present invention provides a message transmission method, device and storage medium. The message transmission method can be applied to network element equipment.

[0024] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0025] Please refer to Figure 1 , Figure 1 A schematic flow chart of the steps of a message transmission method provided by an embodiment of the present invention.

[0026] like Figure 1 As shown, the message transmission method includes steps S101 to S105.

[0027] Step S101: Establish multiple communication links with target devices, and determine at least two target communication links from the multiple communication links.

[0028] Please refer to Figure 2 , Figure 2 A schematic diagram of a scenario for implementing the message transmission method provided in an embodiment of the present invention.

[0029] like Figure 2As shown, multiple communication links are established between the network element device and the target device, wherein the communication link may be a QoS (Quality of Service) link, a session, a bearer, etc., which is not limited here.

[0030] Exemplarily, the target device may be a target terminal device, such as a mobile phone, tablet computer, laptop computer, desktop computer, personal digital assistant, wearable device or other electronic device; it may also be a target network element device, which is not limited here.

[0031] Exemplarily, when transmitting a target message between a network element device and a target device, in order to ensure the reliability of communication quality, at least two target communication links between the network element device and the target device are used to transmit target messages with the same message information, so as to prevent the target message from being lost due to abnormal conditions such as failure or congestion of the communication link when transmitting the target message through one communication link in the related art. The number of target messages can be determined according to actual needs.

[0032] In some embodiments, the network element device includes a business management function network element and a user plane function network element. The establishing of multiple communication links with the target device and determining at least two target communication links from the multiple communication links include: establishing multiple communication links with the target device through the user plane function network element; and determining at least two target communication links from the multiple communication links according to the instructions of the business management function network element.

[0033] Please refer to Figure 3 , Figure 3 A schematic diagram of a scenario for implementing the message transmission method provided in an embodiment of the present invention.

[0034] like Figure 3 As shown, the network element device can be a network element in the 5G core network. Specifically, the core network establishes a communication link with the target device through the user plane function network element (User Plane Function, UPF): communication link 1, communication link 2, ..., communication link N, N is a positive integer greater than 2, wherein the communication link can be, for example, Qosflow: Qosflow1, Qosflow2, ..., QosflowN; it can also be a session: Session1, Session2, ..., SessionN; it can also be a bearer: Bearer1, Bearer2, ..., BearerN, which is not limited here. In addition, the service management function network element (Session Management Function, SMF) in the core network also establishes signaling links with the UPF and the target device respectively, and the SMF can instruct the UPF to communicate with the target device through at least two target communication links through the signaling link.

[0035] In some embodiments, the target device includes a target terminal device; establishing multiple communication links with the target device and determining at least two target communication links from the multiple communication links includes: establishing multiple communication links with the target terminal device and sending target communication link information to the target terminal device, wherein the target communication link information is used to instruct the target terminal device to send the target message through at least two target communication links.

[0036] Please refer to Figure 4 , Figure 4 A schematic diagram of a scenario for implementing the message transmission method provided in an embodiment of the present invention.

[0037] like Figure 4 As shown, the target device for establishing a communication link with the network element device may be a target terminal device, such as various types of user equipment (UE). Specifically, the SMF sends target communication link information, such as a link identifier of the target communication link, to the UPF through a signaling link, instructing the UPF to enable the communication link corresponding to the link identifier as the target communication link.

[0038] In some embodiments, the target device includes a target network element device; establishing multiple communication links with the target device and determining at least two target communication links from the multiple communication links includes: establishing multiple communication links with the target network element device, transmitting a third negotiation message to the target network element device through the multiple communication links, and receiving a fourth negotiation message transmitted by the multiple communication links of the target network element device; determining at least two target communication links from the multiple communication links based on at least one of the third negotiation message and the fourth negotiation message.

[0039] Please refer to Figure 5 , Figure 5 A schematic diagram of a scenario for implementing the message transmission method provided in an embodiment of the present invention.

[0040] like Figure 5 As shown, the target device for establishing a communication link with the network element device may also be a target network element device, such as other network element devices in the core network. Specifically, the SMF and the target network element device determine the target communication link through at least one of the third negotiation message and the fourth negotiation message.

[0041] Exemplarily, SMF can instruct the target network element device to obtain the communication quality of multiple communication links through the third negotiation message. The target network element device sends the communication quality of multiple communication links to SMF through the fourth negotiation message. SMF determines the target communication link based on the content of the fourth negotiation message, and instructs UPF to send and receive messages through the target communication link.

[0042] Alternatively, the target communication link can also be determined through a third negotiation message. For example, the target network element first sends a fourth negotiation message to instruct the SMF to obtain information about multiple communication links from the UPF, and then the SMF sends a third negotiation message to the target network element. At the same time, the SMF determines the target communication link based on the information in the third negotiation message.

[0043] In some embodiments, establishing multiple communication links with the target device and determining at least two target communication links from the multiple communication links also includes: acquiring contract information and / or configuration information of the target device based on a communication request of the target device; establishing multiple communication links with the target device based on the contract information and / or configuration information, and determining at least two target communication links from the multiple communication links.

[0044] Exemplarily, in the related art, message transmission between the target device and the target device is usually achieved through a communication link. However, if the communication link is abnormal, the target device will not be able to receive the target message. Therefore, in scenarios where high-reliability communication is required, a redundant mechanism is used for message transmission. Specifically, there will be at least two target communication links between the network element device and the target device at the same time, and the target messages transmitted respectively in at least two target communication links have the same message information. Taking the case where the target device receives the target message as an example, if the target device receives the target message sent by any target communication link, it can be regarded that the target device has received the target message, and the target messages sent on other target communication links are redundant messages.

[0045] Exemplarily, based on the contract information of the target device, it can be determined whether the target device is a device that requires highly reliable communication. Specifically, for example, when the target device is a target terminal device, it can be determined whether the target terminal device has a demand for highly reliable communication based on the indication of the contract information of the target terminal device. Of course, it is not limited to this, and it is also possible to determine whether the target device is a device that requires highly reliable communication based on the contract information of the target device, for example, determining whether the target network element device has a demand for highly reliable communication based on the indication of the configuration information of the target network element device.

[0046] Exemplarily, for a target device that requires high-reliability communication, multiple communication links are established between the network element device and the target device, and at least two target communication links are determined.

[0047] Exemplarily, establishing multiple communication links with the target device and determining at least two target communication links from the multiple communication links includes: determining a preset number of the target communication links based on the contract information; and determining the preset number of target communication links from the multiple communication links.

[0048] Exemplarily, the number of target communication links may also be determined according to the contract information. Specifically, a preset parameter for indicating the number of target communication links may be set in the contract information of the target device.

[0049] Exemplarily, the preset number of target communication links may be a positive integer greater than 1, such as 2, 3, etc., which is not limited here.

[0050] Step S102: at least two target messages are transmitted between the network element device and the target device through at least two of the target communication links, and at least two of the target messages have the same message information.

[0051] Exemplarily, at least two target messages are transmitted between the network element device and the target device through at least two of the target communication links. The network element device may send at least two target messages to the target device through at least two target communication links, and the target device receives at least two target messages sent by the network element device through at least two target communication links. Alternatively, the target device may send at least two target messages to the network element device through at least two target communication links, and the network element device receives at least two target messages sent by the target device through at least two target communication links. This is not limited here.

[0052] Step S103: Monitor the communication quality of at least two of the target communication links, and determine an abnormal communication link with communication abnormality from the at least two target communication links according to the communication quality monitoring result.

[0053] Exemplarily, step S103 may be executed synchronously with step S102, for example, in the process of transmitting at least two target messages between the network element device and the target device through at least two target communication links, the communication quality of at least two target communication links is monitored.

[0054] Exemplarily, the abnormal communication link is a link in the target communication link whose communication quality is abnormal, for example, the target communication link is faulty or blocked.

[0055] Exemplarily, whether the target communication link is an abnormal communication link can be determined based on the message transmission information on the target communication link. For example, if the message transmission delay on the target communication link is greater than the preset delay, the target communication link is determined to be an abnormal communication link. Of course, it is not limited to this. For example, the abnormal communication link can also be determined based on whether the transmission rate is less than the preset rate, which is not limited here.

[0056] Exemplarily, when an abnormality occurs in a target communication link, a replacement communication link is determined to replace the abnormal communication link, ensuring that a preset number of communication links exist simultaneously for transmitting the target message, thereby improving the reliability of message transmission.

[0057] Step S104: determine at least one replacement communication link from the preset candidate communication links, and use the replacement communication link to replace the abnormal communication link to update at least one abnormal communication link in the at least two target communication links.

[0058] Exemplarily, the candidate communication link is a communication link other than the target communication link among the multiple communication links established in step S101.

[0059] Exemplarily, determining at least one replacement communication link from preset candidate communication links may be determined randomly, or may be determined based on a preset rule, which is not limited herein.

[0060] In some embodiments, determining at least one replacement communication link from preset candidate communication links, and replacing the abnormal communication link with the replacement communication link to update at least one abnormal communication link among at least two target communication links, includes: detecting the communication quality of the candidate communication link through the service management function network element, wherein the candidate communication link is a communication link other than the target communication link; determining the replacement communication link from the candidate communication links according to the communication quality of the candidate communication link, and instructing the user plane function network element to replace the abnormal communication link with the replacement communication link.

[0061] Exemplarily, the replacement communication link may be determined by the SMF. Figure 3 As shown, SMF obtains the communication quality of each target communication link between the target device and UPF through the signaling link, and determines the replacement communication link based on the communication quality.

[0062] Taking the message transmission rate as an example, the SMF may instruct the UPF to determine the link with the highest message transmission rate among the candidate communication links as the replacement communication link, but this is certainly not limited to this and is not limited here.

[0063] In some embodiments, the method of determining at least one replacement communication link from preset candidate communication links and replacing the abnormal communication link with the replacement communication link to update at least one abnormal communication link among at least two target communication links also includes: a first negotiation message sent by the user plane function network element to the target device, and a second negotiation message received by the user plane function network element from the target device, to determine at least one replacement communication link from the preset candidate communication links.

[0064] Exemplarily, the replacement communication link may also be determined by negotiation between the UPF and the target device, by sending a first negotiation message and a second negotiation message between the UPF and the target device to each other, thereby determining the replacement communication link from preset candidate communication links.

[0065] Exemplarily, the order of sending the first negotiation message and the second negotiation message is not limited here. The UPF may send the first negotiation message to the target device first, or the target device may send the second negotiation message to the UPF first.

[0066] Exemplarily, the replacement communication link may be determined from preset candidate communication links according to the transmission rates of the first negotiation message and the second negotiation message, for example, the message transmission rate of the candidate communication link is determined according to the sending and receiving conditions of the first negotiation message and the second negotiation message, and the candidate communication link with the highest message transmission rate is determined as the replacement communication link. Of course, this is not limited to this and is not limited here.

[0067] Exemplarily, the number of determined replacement communication links corresponds to the number of abnormal communication links.

[0068] In some embodiments, determining at least one replacement communication link from preset candidate communication links, and using the replacement communication link to replace the abnormal communication link to update at least one abnormal communication link among at least two target communication links, includes: copying the target message, and transmitting the copied target message through the replacement communication link, wherein the target message includes copy information, and the copy information is used to enable the target device to perform redundancy processing on at least two received copies of the target message.

[0069] Exemplarily, in order to achieve highly reliable communication, a target message with the same message information is sent through at least two target communication links. When sending the target message, the network element device copies the target message and sends it through different target communication links; when receiving the target message, the target device identifies and eliminates redundancy based on the copy information. Specifically, the target device only needs to obtain the message information of the first received target message and read the copy information in the target message. If a target message with the same copy information is subsequently received, it only needs to discard the target message with the same copy information, thereby reducing the data processing burden of the target device.

[0070] Step S105: Utilize the updated at least two target communication links to transmit the target message.

[0071] Exemplarily, the replacement communication link is used to replace an abnormal communication link in the target communication link, that is, among the at least two target communication links after update, the abnormal communication link is replaced by the replacement communication link determined in step S104, ensuring that a preset number of communication links exist at the same time for transmitting the target message, thereby improving the reliability of message transmission.

[0072] Please refer to Figure 6 , Figure 6 A schematic diagram of a scenario for implementing the message transmission method provided in an embodiment of the present invention.

[0073] like Figure 6 As shown, the network element device may include two or more sub-network element devices, such as a first UPF and a second UPF, and can be connected to multiple target devices, such as a first target device and a second target device. The sub-network element devices in the network element device can negotiate with each other to ensure that the number of target communication links for simultaneously transmitting target messages with the target devices is a preset number.

[0074] For example, the communication link between the network element device and the first target device includes: a first communication link a connected to the first UPF, a first communication link b connected to the first UPF, a first communication link c connected to the second UPF, and a first communication link d connected to the second UPF. The first UPF and the second UPF determine a preset number of target communication links from the communication links a, b, c, and d through negotiation, for example, communication links a and c are determined as target communication links; if an abnormal communication link occurs, for example, if the communication link c is abnormal, the first UPF and the second UPF determine the communication link b or d as a replacement communication link through negotiation, and replace the abnormal communication link c with the communication link b or d.

[0075] Exemplarily, the message transmission method implemented on the communication link between the network element device and the second target device is similar to the above process and will not be described in detail here.

[0076] See also Figure 7 , Figure 7 A schematic block diagram of the structure of a network element device provided in an embodiment of the present invention.

[0077] like Figure 6 As shown, the network element device 300 includes a processor 301 and a memory 302, and the processor 301 and the memory 302 are connected via a bus 303, such as an I2C (Inter-integrated Circuit) bus.

[0078] Specifically, the processor 301 is used to provide computing and control capabilities to support the operation of the entire network element device. The processor 301 can be a central processing unit (CPU), and the processor 301 can also be other general-purpose processors, digital signal processors (DSP), application-specific integrated circuits (ASIC), field-programmable gate arrays (FPGA) or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components, etc. Among them, the general-purpose processor can be a microprocessor or the processor can also be any conventional processor, etc.

[0079] Specifically, the memory 302 may be a Flash chip, a read-only memory (ROM) disk, an optical disk, a USB flash drive, or a mobile hard disk.
