Description

Technical Field

[0001] The present invention relates to a 5G technical field, and in particular to a monitoring method, system, device and storage medium for a 5G Internet of Things terminal. Background Art

[0002] 5G terminals are increasingly being used, and are increasingly being used in the Internet of Things. 5G IoT terminals are used for environmental monitoring, traffic monitoring, climate monitoring, forest fire prevention, and hydrological monitoring, etc. The access method is to establish a wireless channel between the 5G module and the 5G base station, and finally access the Internet through the core gateway of the base station uplink. At the same time, the monitoring platform at the other end of the Internet of Things directly uses a public network address. The 5G terminal can establish communication with the public network address of the monitoring platform using the private network address assigned by the base station side. The communication relationship is as follows: Figure 1 shown.

[0003] In order to uniformly monitor all 5G terminals, 5G terminals need to send handshake messages to the monitoring platform regularly to prove that they are online. In the prior art, 5G terminals use core routers to convert private network addresses into public network addresses, so that messages can reach the Internet and communicate with the public network address of the monitoring platform. The main handshake mechanisms used include private protocols and ICMP protocols.

[0004] Among them, since multiple 5G terminals may not be provided by the same manufacturer, it is costly to support private protocols and the implementation of private protocols is cumbersome. Therefore, the ICMP protocol has been widely used, but when multiple 5G terminals convert private network addresses to public network addresses, the public network addresses may be the same or partially the same, making it impossible for the monitoring platform to determine which 5G terminal's communication link is normal, affecting the monitoring quality of 5G terminals.

[0069] 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 only 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.

[0070] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0071] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein are only for the purpose of describing the embodiments of the present invention and are not intended to limit the present invention.

[0072] In order to monitor and manage 5G IoT terminals, 5G IoT terminals need to periodically send handshake messages to the monitoring platform to let the monitoring platform know that they are online. Limited by the number and cost of public IPs, most 5G IoT terminals use private IPs and monitoring platforms use public IPs. When a 5G IoT terminal sends a handshake message to the corresponding monitoring platform, the private network source IP address message is usually subjected to network address translation (NAT) through a core router, and finally converted to a public network source IP address to reach the Internet and communicate with the monitoring platform. The monitoring platform cannot actively communicate with the 5G IoT terminal because it cannot find the route on the 5G IoT terminal side. When the monitoring platform needs to receive handshake messages transmitted by multiple 5G IoT terminals, the converted public network addresses of multiple 5G IoT terminals may be the same, making it impossible for the monitoring platform to determine which 5G IoT terminal is online. Based on this, an embodiment of the present application discloses a monitoring method for 5G IoT terminals, such as Figure 2 As shown, the method includes:

[0073] S101. After obtaining a handshake instruction, call a network management command to generate a target message.

[0074] The 5G IoT terminal needs to periodically send a handshake message to the corresponding monitoring platform. Therefore, on the 5G IoT terminal side, a handshake instruction will be periodically received or generated to start the handshake message sending process. In one embodiment, the 5G IoT terminal will receive a handshake instruction every time a preset time period passes; the handshake instruction includes but is not limited to a clock signal. In another embodiment, the 5G IoT terminal will generate a handshake instruction every time a preset time period passes. Among them, the handshake instruction can be generated by a timer or by a processing chip. It should be noted that whether the 5G IoT terminal receives a handshake instruction or generates a handshake instruction, it is determined that the handshake instruction has been obtained.

[0075] After the 5G Internet of Things terminal obtains the handshake instruction, or when the handshake instruction is obtained, the network management command is called, and the target message is generated by the called network management command. Among them, the network management command refers to a command that can generate a message, including but not limited to the ping command. The target message generated based on the ping command is an IP message. Specifically, the type of the target message is an ICMP message. In addition, the message is a data unit exchanged and transmitted in the network, which contains the complete data information to be sent. The length is not limited and the length can be changed. In this embodiment, the target message generated by the called network management command is the handshake message that needs to be transmitted to the corresponding monitoring platform. S102. Write the terminal information into the fill segment of the target message based on the preset fill format.

[0076] In one embodiment, the target message includes an Ethernet header, an IP header, an ICMP header and a data field, wherein the data field is a padding segment. By writing the terminal information of the 5G Internet of Things terminal into the target message, multiple target messages received by the same monitoring platform can carry the terminal information of the corresponding 5G Internet of Things terminal, so that the monitoring platform can distinguish the source of each target message. After the monitoring platform knows the source of each target message, it can know which 5G Internet of Things terminals are online to realize the monitoring of the 5G Internet of Things terminal. In addition, since the protocol stack of the monitoring platform will not do any processing on the data field of the target message after receiving the target message, based on this mechanism, the terminal information is written in the padding segment, which can ensure the integrity and accuracy of the terminal information, and is not easy to be lost or tampered with, thereby improving the monitoring quality.

[0077] S103: Transmit the target message to the monitoring platform.

[0078] In one embodiment, a target message containing corresponding terminal information in the filling segment is sent to a corresponding monitoring platform, so that the monitoring platform can learn the terminal information from the target message, thereby locking the corresponding 5G Internet of Things terminal, enabling the monitoring platform to accurately monitor the 5G Internet of Things terminal and improving the monitoring quality.

[0079] In another embodiment of the present invention, in order to further define and illustrate, Figure 3 As shown, the step of writing the terminal information into the filling segment of the target message based on the preset filling format includes:

[0080] S201. Obtain a filling category and a filling order based on a filling format.

[0081] S202: Obtain corresponding terminal information based on the filling category.

[0082] S203: Fill the terminal information into the filling segment of the target message according to the filling order.

[0083] On the one hand, in order to enable the monitoring platform to identify the corresponding 5G IoT terminal through terminal information and improve the monitoring quality, the filling format constrains the filling category; on the other hand, in order to improve the writing efficiency of terminal information and the convenience of the monitoring platform reading the target message filling segment, the filling order is constrained to improve the monitoring efficiency.

[0084] Among them, in one embodiment, the filling format only includes the filling category, and the so-called filling category includes but is not limited to the terminal serial number, terminal manufacturer, terminal software version number, assigned 5G private network IP and check code, and there is no limit on the filling category and the number of filling categories. It is intended to enable the monitoring platform to lock the corresponding 5G Internet of Things terminal through the detailed information of the filling category. In this embodiment, the filling order is the arrangement order of the filling categories.

[0085] In other embodiments, the filling format includes a filling order in addition to the filling category. When filling the terminal information into the filling segment, it is performed according to the filling order. This facilitates orderly arrangement of the contents in the filling segment when there are a large number of filling categories, and efficient parsing of the monitoring platform, and quick search for the required terminal information.

[0086] In other embodiments, the filling order is the time sorting of the 5G Internet of Things terminal obtaining the terminal information corresponding to the filling category, that is, after obtaining the filling category through the filling format, the terminal information is obtained according to the filling category, and the terminal information obtained first is arranged in front, which is used as the filling order.

[0087] In one embodiment, the terminal information is stored in the memory of the corresponding 5G IoT terminal. According to the name or number of the filling category, the corresponding terminal information can be retrieved from the specified storage path or storage table. In other embodiments, after obtaining the filling category, the 5G IoT terminal outputs the filling category and then receives the terminal information transmitted by other terminals or input devices. Among them, the other terminal can be a database server, etc.

[0088] In another embodiment of the present invention, for further definition and explanation, before the step of filling the terminal information into the filling segment of the target message according to the filling order, the method includes:

[0089] Determine whether the padding length of the padding segment is less than the required length of the terminal information.

[0090] If so, configure the byte space of the padding segment to increase the padding length.

[0091] According to the mechanism of variable message length, in order to ensure that the terminal information of all filling categories can be written into the filling segment, the length of the filling segment is expanded to ensure the integrity of the terminal information and meet the requirements of the filling format. At the same time, it is also easy to meet the transmission of terminal information, so that more terminal information can be transmitted to the monitoring platform for other processing, and the purpose of the target message transmitted between the 5G IoT terminal and the monitoring platform can be expanded.

[0092] Specifically, in one embodiment, the padding length and the required length of the terminal information both refer to the number of bytes, such as 32 bytes, 128 bytes, and 256 bytes. After obtaining the terminal information, the required length can be estimated based on the terminal information, and then the padding length of the padding segment in the target message can be compared to obtain the size relationship between the two. In another embodiment, after the required length is estimated based on the terminal information, it is compared with the overall length of the target message. When the required length is less than the partial length of the target message, the byte space of the padding segment is configured. It should be noted that for a fixed application scenario, the lengths of the Ethernet header, IP header, and ICMP header in the target message are all fixed, that is, the proportion of the total length of the Ethernet header, IP header, and ICMP header in the target message length is certain and known, so that it can be obtained whether the padding length needs to be expanded.

[0093] In one embodiment, after configuring the byte space of the filling segment, the expansion request is transmitted to the operating system of the 5G IoT terminal, and the operating system expands the filling length. The expansion request can represent the number of bytes of the filling segment to be applied for, or it can represent the number of bytes of the target message to be applied for. In this embodiment, the expansion request applies to set the target message to 256 bytes.

[0094] In addition, in one embodiment, before the step of filling the terminal information into the filling segment of the target message according to the filling order, the step includes:

[0095] Configure the byte space of the padding segment to expand the padding space.

[0096] That is, the size between the padding length and the required length is no longer judged, but the target message is directly expanded to 256 bytes, which is conducive to reducing the execution steps and improving the efficiency of the 5G IoT terminal transmitting handshake messages to the monitoring platform, thereby improving the monitoring efficiency and saving network resources.

[0097] In another embodiment of the present invention, for further definition and explanation, after the step of filling the terminal information into the filling segment of the target message according to the filling order, the method includes:

[0098] Determine whether there is any remaining byte space in the padding segment.

[0099] If so, fill the remaining byte space with the preset placeholder information.

[0100] In order to fix the length of the target message, the unused space of the padding segment is occupied by placeholder information, which ensures the standardization and uniformity of the target message generated by the 5G IoT terminal. The placeholder information includes but is not limited to padding; the value of padding is 0.

[0101] For ease of understanding, Figure 4 As shown, in an application scenario, after the timer generates a handshake instruction, the handshake instruction triggers the start of a ping packet, which contains a ping program, and the ping program generates a network management command, namely, a ping command. Then configure the byte space of the padding segment and apply for a 256-byte ICMP message, namely, the target message. The ping command generates a 256-byte ICMP message, fills the IP header, wherein the IP header includes the destination IP and the source IP; fills the ICMP header, wherein the ICMP type is 8; fills the data field, namely, the padding segment, wherein the filling content of the data field is the magic word, the terminal serial number, the manufacturer, the version number and the private network address, and the check value of the magic word, the terminal serial number, the manufacturer, the version number and the private network address. Use padding to occupy the space, ensure that the length of the ICMP message is fixed, and output the ICMP message.

[0102] The present application embodiment discloses a monitoring method for a 5G Internet of Things terminal, such as Figure 5 As shown, the method includes:

[0103] L101. After receiving the target message, determine whether the target message meets the preset message requirements.

[0104] In one embodiment, the target message is a message whose filling segment carries the terminal information of the corresponding 5G Internet of Things terminal, and the target message is an IP message, and the specific type belongs to an ICMP message. Among them, the monitoring platform is preset with a message requirement, and the message requirement is used to determine whether the received target message is a handshake message transmitted by the 5G Internet of Things terminal, thereby determining the subsequent processing of the received target message. For example, in an application scenario, if the target message is not a handshake message transmitted by the 5G Internet of Things terminal after judgment, the target message is directly discarded or transmitted to the protocol stack for subsequent processing; if it is a handshake message, subsequent processing is performed. In addition, the usability and security of the target message can also be verified according to the message requirements. For example, if it is verified according to the message requirements that the target message does not carry terminal information, that is, there is no terminal information in the filling segment, then the target message is not usable.

[0105] L102. When the target message meets the message requirements, obtain the terminal information carried by the target message.

[0106] In one embodiment, the target message meets the message requirements, which proves that the target message is a handshake message sent by the 5G IoT terminal to the monitoring platform, and the target message is usable. At this time, the terminal information is obtained, and the 5G IoT terminal corresponding to the target message can be known through the terminal information, so as to lock the 5G IoT terminal and consider that the 5G IoT terminal is online. The monitoring process of the monitoring platform can accurately lock each 5G IoT terminal according to the target message, reduce the error rate and the discard rate of the target message, and improve the monitoring quality and efficiency.

[0107] L103. Update the handshake information of the corresponding IoT terminal based on the terminal information.

[0108] Among them, the IoT terminal is a 5G IoT terminal. The terminal information includes information that can represent the uniqueness of the 5G IoT terminal, so that the monitoring platform can know which 5G IoT terminal sent the target message, so that the monitoring platform can update the handshake information of the corresponding 5G IoT terminal. Through the handshake information, the online status of the 5G IoT terminal under the control of the monitoring platform can be known, and the 5G IoT terminal can be monitored.

[0109] In another embodiment of the present invention, in order to further define and illustrate, Figure 6 As shown, the steps for determining whether the target message meets the preset message requirements include:

[0110] L201. Get the storage address of the target message.

[0111] In order to verify whether the target message is a handshake message transmitted by the 5G IoT terminal and the availability of the target message, in one embodiment, the hook function packet_ptr is used to execute step L101. Therefore, the storage address of the target message is transmitted to the hook function so that the hook function obtains it. It is convenient to use the hook function to parse the target message, and it is also helpful to parse the target message in an orderly manner when the monitoring platform receives multiple target messages, thereby reducing the error rate.

[0112] L202. Determine whether the target message is an IP message.

[0113] In one embodiment, it is determined whether the Ethernet header eth.type in the target message is 0x800; if so, it is determined that the target message is an IP message, otherwise the target message is transmitted to the protocol stack on the monitoring platform side.

[0114] When the target message is an IP message, L203 determines whether the target message is an ICMP message.

[0115] In one embodiment, it is determined whether the IP header ip.ip_p is 1; if so, it is determined that the target message is an ICMP message, otherwise the target message is transmitted to the protocol stack on the monitoring platform side.

[0116] When the target message is an ICMP message, L204, obtain the field address of the padding segment in the target message.

[0117] In one embodiment, the field address of the padding segment is derived based on the Ethernet header length, the IP header length and the ICMP header length. Specifically, the field address of the padding segment = packet_ptr + Ethernet header length + IP header length + ICMP header length.

[0118] L205. Determine whether the padding segment carries terminal information based on the field address.

[0119] In one embodiment, after obtaining the field address, the starting position of the padding segment in the target message is known. The first field obtained from the starting position is the magic word. It is determined whether the magic word is 0x88991122; if so, it proves that the information in the padding segment is available and edited; if not, it proves that the padding segment does not have terminal information.

[0120] When the filling segment carries the terminal information, L206 generates a check code and determines whether the check code matches a preset check code.

[0121] In one embodiment, a check code is generated by term_info calculation and compared with a preset check code. If they are the same, they match, and if they are different, they do not match. The preset check code refers to the check code in the padding segment of the target message. Through the above steps to determine whether the target message meets the message requirements, on the one hand, the entire judgment process does not require manual intervention and is automatically executed, which can improve the efficiency and accuracy of the target message verification process; on the other hand, the information carried by the target message, such as the Ethernet header, IP header, etc., is verified one by one, which is convenient for improving the accuracy of the handshake information updated by the monitoring platform and improving the monitoring quality.

[0122] It should be noted that the field address of the filling segment is known in step L204, and part of the terminal information in the filling segment is subsequently read according to the field address. Step L102 can read all the terminal information in the filling segment according to the field address.

[0123] In another embodiment of the present invention, in order to further define and illustrate, Figure 7 As shown, the steps of updating the handshake information of the corresponding IoT terminal based on the terminal information include:

[0124] L301. Obtain the terminal serial number from the terminal information.

[0125] In one embodiment, the terminal information includes a terminal serial number. In one application scenario, the terminal serial number is searched in the terminal information according to the identifier of the terminal serial number, thereby obtaining the terminal serial number. In another application scenario, since the terminal information in the padding segment has a padding order, the terminal serial number can be searched according to the padding order, thereby obtaining the terminal serial number. In other application scenarios, the terminal serial number can also be found by combining the length of each type of terminal information, the field address of the padding segment, and the padding order.

[0126] L302. When a terminal serial number exists in the preset terminal information table, the handshake time of the corresponding IoT terminal in the terminal information table is updated to the current time, and the accumulated handshake times of the corresponding IoT terminal are increased.

[0127] In order to facilitate the monitoring of 5G IoT terminals, the terminal serial number is used to identify whether the handshake information of the corresponding 5G IoT terminal has been stored in the terminal information table. If so, it is directly updated on the basis of the handshake time. Among them, the handshake time is convenient for knowing the last online time of the 5G IoT terminal; the number of handshakes is convenient for knowing the length of time the 5G IoT terminal has been online since the start of monitoring, which improves the monitoring accuracy of the monitoring platform for 5G IoT terminals.

[0128] It should be noted that before executing step L302, in one embodiment, the monitoring platform searches the terminal information table to see whether there is a terminal serial number that is the same as the terminal serial number. If so, it proves that a handshake message related to the corresponding 5G Internet of Things information is stored in the terminal information table, and the update can be performed directly based on it.

[0129] L303. When the terminal serial number does not exist in the terminal information table, the terminal information, handshake time and handshake number are recorded in the terminal information table.

[0130] In order to record the handshake information in time and monitor the 5G IoT terminal, it is necessary to explain that, in one embodiment, in order to ensure that the handshake information of the 5G IoT terminal is stored in time and not easily lost, before the step of updating the handshake information of the corresponding IoT terminal based on the terminal information, the following steps are included:

[0131] Determine whether the terminal information table exists.
