Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0076] It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the presence of the features declared thereafter, but does not exclude the addition of other features.

[0077] Based on the defects of passive Internet of Things terminals in storage capacity and computing power, the present scheme respectively provides a two-way pairing strategy from the Internet of Things terminal side and the relay node device side to realize the pairing of the Internet of Things terminal and the relay node device, so that the data collected by the Internet of Things terminal can be uploaded to the relay node device first, and then forwarded to the base station for final data processing after being processed by the relay node device.

[0078] The pairing method of the present scheme increases the flexibility and success rate of pairing. And it realizes the multi-connection pairing method of the Internet of Things terminal and the relay node device, fully excavates the network transmission performance of the Internet of Things terminal and the relay node device, and improves the data transmission efficiency.

[0079] Figure 1 Flowchart of the device pairing method provided by the embodiments of the present application Figure One The following embodiments are described in detail around the steps performed by the method when applied to the Internet of Things terminal side. As shown in Figure 1 The method can include:

[0080] S101, send the position information and identification information of the Internet of Things terminal to each relay node device, and receive the distance information of each relay node device and the Internet of Things terminal sent by each relay node device.

[0081] One Internet of Things terminal can establish an initial connection with one or more relay node devices, and send the position information and identification information of the Internet of Things terminal to each relay node device with which an initial connection is established.

[0082] And one relay node device can receive position information and identification information sent from different Internet of Things terminals, so that one relay node device can send the distance information of the relay node device and each Internet of Things terminal to each corresponding Internet of Things terminal.

[0083] The relationship between the Internet of Things terminal and the relay node device is many-to-many, that is, any Internet of Things terminal can send location information and identification information to multiple relay node devices, and can also receive distance information sent by multiple relay node devices, and any relay node device can receive location information and identification information sent by multiple Internet of Things terminals, and can send corresponding distance information to multiple Internet of Things terminals.

[0084] The relay node device can include but is not limited to the following types: 5G terminal (NR UE); LTE terminal (LTE UE); NB-IoT terminal; dedicated relay base station; wireless CPE node; edge computing platform; edge gateway; same type of Internet of Things terminal; third-party power device with protocol conversion function; third-party power amplifier and forwarding device compatible with transmission protocol.

[0085] The location information of the Internet of Things terminal can refer to coordinate information, which includes but is not limited to the following information: GPS (Global Positioning System) system positioning coordinate information; Beidou system positioning coordinate information; GLONASS (GLObal Navigation Satellite System) system positioning coordinate information; absolute coordinate positioning information; relative coordinate positioning information; real-time coordinate positioning information.

[0086] The identification information of the Internet of Things terminal includes but is not limited to the following information: ID (Identity document) information; product serial number; Name information; IP (Internet Protocol) address information; MAC (Media Access Control) address information; device manufacturer information. Among them, the ID information in the identification information of the Internet of Things terminal includes but is not limited to the following information: device identification information; device serial number information; temporary mobile user identity information; global unique temporary mobile user identity information; wireless network temporary identification information.

[0087] Optionally, the distance information between the Internet of Things terminal and the relay node device in the embodiment can refer to the Euclidean distance between the Internet of Things terminal and the relay node device.

[0088] S102, according to the service demand information, determine the number of required relay node devices.

[0089] The number of relay node devices required to be paired by different Internet of Things terminals when performing different services is different, and the Internet of Things terminal, service requirement, and required relay node device to be paired have a mapping relationship. The number of relay node devices required to be paired by the Internet of Things terminal can be determined according to the service requirement information to be currently performed.

[0090] That is, a set number of relay node devices need to be paired to complete the service.

[0091] S103, determine the number of relay node devices currently allowed to be paired according to the capability information of the Internet of Things terminal. The capability information is used to represent the load state of the Internet of Things terminal.

[0092] Generally, the capability information of the Internet of Things terminal is used to represent the load state of the Internet of Things terminal. In the embodiment, the capability information of the Internet of Things terminal includes but is not limited to the following information: Internet of Things terminal current available power information; upper limit information of the number of relay node devices allowed to be connected by the Internet of Things terminal at the same time; upper limit information of the number of relay node devices allowed to be paired by the Internet of Things terminal at the same time; identification information of the relay node device currently connected by the Internet of Things terminal; identification information of the relay node device currently paired by the Internet of Things terminal; identification information of the relay node device historically paired by the Internet of Things terminal.

[0093] The concept that needs to be distinguished is that the relay node device connected by the Internet of Things terminal can refer to the relay node device with which the Internet of Things terminal has established an initial connection and can perform transmission of basic information such as position information and coordinate information. The relay node device paired by the Internet of Things terminal can refer to the relay node device that has established an initial connection and has successfully paired. The Internet of Things terminal and the relay node device can perform transmission of collected data after successful pairing.

[0094] The number of relay node devices currently allowed to be paired by the Internet of Things terminal can be determined according to the capability information of the Internet of Things terminal.

[0095] S104, determine at least one candidate relay node device from each relay node device according to the number of relay node devices required to be paired, the number of relay node devices currently allowed to be paired, and the distance information of each relay node device from the Internet of Things terminal.

[0096] Based on the number of relay node devices required to be paired by the Internet of Things terminal, the number of relay node devices currently allowed to be paired, and the distance information of each relay node device from the Internet of Things terminal determined above, at least one candidate relay node device can be determined from each relay node device.

[0097] The embodiment focuses more on implementing multi-connection between the Internet of Things terminal and the relay node device, and a plurality of candidate relay node devices can be determined from the plurality of relay node devices to connect more relay node devices within the capability of the Internet of Things terminal, thereby improving the data transmission efficiency between the Internet of Things terminal and the relay node device.

[0098] In step S105, a pairing request is sent to each candidate relay node device, and a pairing result fed back by each candidate relay node device is received. The pairing result includes pairing success or pairing failure.

[0099] Optionally, the Internet of Things terminal can send a pairing request to each candidate relay node device, and receive a pairing result fed back by each candidate relay node device. When the pairing result is pairing success, the Internet of Things terminal and the candidate relay node device are paired successfully. When the pairing result is pairing failure, the Internet of Things terminal and the candidate relay node device are paired unsuccessfully. The candidate relay node device with pairing failure can be discarded, and the above method is executed cyclically to determine new candidate relay node devices for pairing until pairing is completed.

[0100] In summary, the device pairing method provided by the embodiment can determine the number of relay node devices currently allowed to be paired by the Internet of Things terminal based on the capability information of the Internet of Things terminal, and accurately determine the number of candidate relay node devices in combination with the number of relay node devices required to be paired by the Internet of Things terminal. That is, the upper limit of the relay node devices that can be paired by the Internet of Things terminal within the capability allowed by the Internet of Things terminal is determined in consideration of the capability information of the Internet of Things terminal, so as to fully utilize the device performance of the Internet of Things terminal and the relay node device, and improve the data transmission efficiency between the Internet of Things terminal and the relay node device. The number of candidate relay node devices that meet the number are determined from the plurality of relay node devices based on the distance information of each relay node device and the Internet of Things terminal. Since the distance information is related to the channel delay and the channel quality signal to a certain extent, the relay node devices are screened through the distance information, so that the pairing success rate of the selected candidate relay node devices and the Internet of Things terminal is higher, and the data transmission stability is also higher.

[0101] Optionally, in step S103, determining the number of relay node devices currently allowed to be paired according to the capability information of the Internet of Things terminal can include: determining the number of relay node devices currently allowed to be paired by the Internet of Things terminal according to the number of relay node devices simultaneously allowed to be paired by the Internet of Things terminal and the number of relay node devices currently paired by the Internet of Things terminal in the capability information of the Internet of Things terminal.

[0102] The content contained in the capability information of the IOT terminal is described above. The capability information can contain various information. In this embodiment, the number of relay node devices that the IOT terminal currently allows to pair can be determined according to the number of relay node devices that the IOT terminal simultaneously allows to pair and the number of relay node devices that the IOT terminal has currently paired in the capability information of the IOT terminal. The number of relay node devices that the IOT terminal has currently paired can be obtained according to the identification information of the relay node devices that the IOT terminal has currently paired.

[0103] Figure 2 Flowchart of the device pairing method provided by the embodiment of the application Figure Two Optionally, in step S104, each candidate relay node device can be determined from each relay node device according to the number of relay node devices required to pair, the number of relay node devices currently allowed to pair, and the distance information of each relay node device from the IOT terminal. This can include:

[0104] S201. Determine the number of candidate relay node devices required according to the number of relay node devices required to pair and the number of relay node devices currently allowed to pair.

[0105] The number of candidate relay node devices required can be determined according to the comparison result of the number of relay node devices required to pair and the number of relay node devices currently allowed to pair.

[0106] S202. Determine the order of each relay node device according to the distance information of each relay node device from the IOT terminal.

[0107] The list of relay node devices corresponding to the IOT terminal can be created according to the distance information of each relay node device from the IOT terminal. The list can contain the identification information of each relay node device connected by the IOT terminal, and can also mark the distance information between the relay node device and the IOT terminal. Optionally, each relay node device in the list of relay node devices can be sorted according to the distance information of each relay node device from the IOT terminal in descending order.

[0108] Of course, creating a list is only to facilitate the display of the order of each relay node device. In actual application, the list can also not be created intentionally.

[0109] S203. Determine each candidate relay node device from each relay node device according to the number of candidate relay node devices required, the identification information of each relay node device currently paired, and the order of each relay node device.

[0110] Based on the determined required number of candidate relay node devices and the identification information of the current and paired relay node devices of the Internet of Things terminal, and the ranking of the relay node devices, each candidate relay node device can be determined from the relay node devices.

[0111] Figure 3 Flowchart of the device pairing method provided by the embodiment of the application Figure Three In step S201, the required number of candidate relay node devices is determined according to the number of required relay node devices to be paired and the number of currently allowed relay node devices to be paired, which can include:

[0112] In step S301, if the difference between the number of required relay node devices to be paired and the number of currently paired relay node devices is greater than the number of currently allowed relay node devices to be paired, the number of currently allowed relay node devices to be paired is determined as the required number of candidate relay node devices.

[0113] Firstly, the number N of relay node devices to be paired currently can be calculated according to the difference between the number of required relay node devices to be paired and the number of currently paired relay node devices.

[0114] When the number N of relay node devices to be paired is greater than the number M of currently allowed relay node devices to be paired, although the number of required relay node devices to be paired is large, due to the capability limitation of the Internet of Things terminal, the Internet of Things terminal only allows pairing of M relay node devices in the case of allowed capability, and then the required number of candidate relay node devices is determined as M, that is, the number of currently allowed relay node devices to be paired of the Internet of Things terminal is determined as the required number of candidate relay node devices.

[0115] In step S302, if the difference between the number of required relay node devices to be paired and the number of currently paired relay node devices is less than or equal to the number of currently allowed relay node devices to be paired, the difference between the number of required relay node devices to be paired and the number of currently paired relay node devices is determined as the required number of candidate relay node devices.

[0116] When the number N of relay node devices still to be paired is less than or equal to the number M of relay node devices currently allowed to be paired, although the capacity of the Internet of Things terminal is sufficient, the number M of relay nodes allowed to be paired is greater than the number N of relay node devices required to be paired to perform the service requirement, but in this scenario, only N relay node devices are required to perform the service. At this time, the number N of relay node devices still to be paired can be determined as the number of required candidate relay node devices. That is, the difference between the number of relay node devices required to be paired and the number of currently paired relay node devices is determined as the number of required candidate relay node devices.

[0117] Optionally, in step S203, determining each candidate relay node device from each relay node device according to the number of required candidate relay node devices, the identification information of the currently paired relay node device, and the ranking of each relay node device can include:

[0118] According to the identification information of the currently paired relay node device, the currently paired relay node device can be removed from each relay node device to obtain the ranking of each remaining relay node device; and each candidate relay node device can be determined from each remaining relay node device according to the number of required candidate relay node devices and the ranking of each remaining relay node device.

[0119] Suppose the number of required candidate relay node devices is 5, then according to the ranking of each relay node device, the top 5 relay node devices can be taken as each candidate relay node device, of course, this is the case when the top 5 relay node devices do not contain the currently paired relay node device.

[0120] When the top 5 relay node devices contain the currently paired relay node device, the currently paired relay node device of the Internet of Things terminal is removed from the 5 relay node devices, and the candidate relay node device is selected from the 6th relay node device in order, and the number of candidate relay node devices is consistent with the number of paired relay node devices removed from the relay node devices.

[0121] Optionally, the method of the present application can further include discarding the candidate relay node device that fails to be paired, and determining a new candidate relay node device until the number of candidate relay nodes successfully paired meets the number of required candidate relay node devices, and then stopping pairing.

[0122] In some embodiments, when the IoT terminal fails to pair with a candidate relay node, the IoT terminal can delete the candidate relay node device that fails to pair, and determine new candidate relay node devices for pairing according to the ranking of the remaining relay node devices. When the number of relay node devices that successfully pair with the IoT terminal meets the required number, pairing is completed and pairing is stopped.

[0123] Figure 4 Flowchart of the device pairing method provided by the embodiments of the present application Figure Four Optionally, the method can further include:

[0124] S401, if a new relay node device is detected to be activated, the new relay node device is taken as a relay node device corresponding to the IoT terminal, and the ranking of the current candidate relay node devices is updated according to the distance information between the new relay node device and the IoT terminal.

[0125] The method further provides an updating method of the relay node device. Optionally, when the IoT terminal detects that a new relay node device is activated, the IoT terminal establishes a connection with the new relay node device, and the ranking of the current candidate relay node devices can be updated according to the distance information between the new relay node device and the IoT terminal.

[0126] S402, if the relay node device corresponding to the IoT terminal is detected to be turned off, the turned-off relay node device is no longer taken as the relay node device corresponding to the IoT terminal.

[0127] In some cases, when the IoT terminal detects that a relay node device connected thereto is turned off, the relay node device is no longer taken as one of the relay node devices of the IoT terminal. The ranking of the relay node devices can change due to the turning off of the existing relay node device, so that the determined candidate relay node devices can also change.

[0128] Through the updating strategy provided by the method, the relay node devices corresponding to the IoT terminal can be updated in real time, so that the selection of the candidate relay node devices is dynamically updated, and the selected candidate relay node devices have the best matching efficiency with the IoT terminal.

[0129] In another implementable manner, the relay node device can also send the capability information of the relay node device to the IoT terminal, and the IoT terminal can determine the candidate relay node devices from the relay node devices according to the capability information of the IoT terminal in combination with the capability information of the relay node device.

[0130] The capability information of the relay node device includes but is not limited to: the upper limit of the number of IoT terminals allowed to be connected by the relay node device at the same time; the upper limit of the number of IoT terminals allowed to be paired by the relay node device at the same time; the identification information of the IoT terminals currently connected by the relay node device; the identification information of the IoT terminals currently paired by the relay node device; the identification information of the IoT terminals historically paired by the relay node device; the current available channel information of the relay node device; the current available computing power information of the relay node device, etc.

[0131] For example: assuming that the candidate relay node device determined by the IoT terminal according to its own capability information includes relay node device 1, and according to the capability information of relay node device 1, it is known that the number of IoT terminals currently allowed to be paired by relay node device 1 has reached the upper limit, then relay node device 1 can be deleted from the candidate relay node device of the IoT terminal.

[0132] Combining the capability information of the IoT terminal and the capability information of the relay node device for comprehensive judgment can make the selected candidate relay node device more accurate.

[0133] In some embodiments, after receiving the pairing request sent by the IoT terminal, the candidate relay node device can detect its node state, and when the detection is passed, it sends a pairing success message to the IoT terminal, and when the detection is not passed, it sends a pairing failure message to the IoT terminal.

[0134] The node state detection includes but is not limited to the following contents: 1. The node has available idle channels; 2. The node has idle computing power resources; 3. The number of terminals matched by the node does not exceed the upper limit value.

[0135] If the above conditions are all met at the same time, the state check is passed; otherwise, the state check is not passed.

[0136] In summary, the device pairing method provided in the embodiment can determine the number of relay node devices that the Internet of Things terminal is currently allowed to pair based on the capability information of the Internet of Things terminal, and can accurately determine the number of candidate relay node devices in combination with the number of relay node devices that the Internet of Things terminal device needs to pair. That is, in the case of considering the capability information of the Internet of Things terminal, the upper limit of the relay node devices that the Internet of Things terminal can pair is determined within the capability allowed range of the Internet of Things terminal, so as to fully utilize the device performance of the Internet of Things terminal and the relay node device and improve the data transmission efficiency between the Internet of Things terminal and the relay node device. The candidate relay node devices that meet the number are determined from the plurality of relay node devices based on the distance information of each relay node device and the Internet of Things terminal. Since the distance information is related to the channel delay and the channel quality signal to a certain extent, the relay node devices are screened through the distance information, so that the pairing success rate of the selected candidate relay node devices and the Internet of Things terminal is higher, and the data transmission stability is also higher.

[0137] The following embodiment takes the relay node device side as the execution subject to supplement the execution process of the device pairing method.

[0138] Figure 5 Process of the device pairing method provided in the embodiment Figure Five The method can include the following steps when applied to the relay node device.

[0139] S501, receiving the position information and the identification information sent by each Internet of Things terminal, and determining the distance information between each Internet of Things terminal and the relay node device according to the position information of the relay node device and the position information of each Internet of Things terminal.

[0140] The process of the pairing method executed on the relay node device side is basically the same as the process of the above-mentioned Internet of Things terminal side. Therefore, the execution steps of the method on the relay node device side are supplemented and will not be described in detail.

[0141] The relay node device can receive the position information sent by each Internet of Things terminal and calculate the distance information between each Internet of Things terminal and the relay node device according to the position information of the relay node device, and send each distance information to the corresponding Internet of Things terminal according to the identification information of each Internet of Things terminal.

[0142] S502, determining the number of Internet of Things terminals needed to be paired according to the business demand information.

[0143] The number of Internet of Things terminals needed to be paired by different relay node devices for different business demands is different. The number of Internet of Things terminals needed to be paired by the relay node device under the current business demand can be determined according to the mapping relationship between the business demand and the number of relay node devices and the number of Internet of Things terminals needed to be paired.

[0144] S503. Determine the number of IoT terminals that can be paired at present based on the capability information of the relay node device. The capability information is used to characterize the load status of the relay node device.

[0145] The above embodiments have described the contents of the capability information of the relay node device, and the number of IoT terminals that the relay node device is currently allowed to pair with can be determined based on the capability information of the relay node device.

[0146] S504. Based on the number of IoT terminals to be paired, the number of IoT terminals currently allowed to be paired, and the distance information between each IoT terminal and the relay node device, determine at least one candidate IoT terminal from the IoT terminals.

[0147] Based on the number of IoT terminals that the relay node device needs to be paired with, the number of IoT terminals that are currently allowed to be paired, and the distance information between each IoT terminal and the relay node device, at least one candidate IoT terminal can be identified from each IoT terminal.

[0148] S505. Based on the node status detection results of the relay node device, send pairing requests to each candidate IoT terminal and receive pairing confirmation messages from each candidate IoT terminal.

[0149] Before sending pairing requests to each candidate IoT terminal, the relay node device can also check its own node status. When the check result is successful, it sends a pairing request to each candidate IoT terminal. For each IoT terminal that receives the pairing request, it does not need to perform further checks. As long as it receives the pairing request, it sends a pairing confirmation message to the relay node device. The pairing confirmation message is used to indicate that the pairing is successful.

[0150] If the detection result fails, the node status can be re-detected after the timer expires, until the detection passes, at which point a pairing request is sent to each candidate IoT terminal.

[0151] In conclusion, the device pairing method provided in this embodiment can determine the number of IoT terminals currently allowed to be paired by the relay node device based on the capability information of the relay node device, and can accurately determine the number of candidate IoT terminals in combination with the number of IoT terminals required to be paired by the relay node device. That is, the upper limit of the IoT terminals that can be paired by the relay node device is determined within the range allowed by the capability of the relay node device, so as to fully utilize the device performance of the IoT terminals and the relay node device and improve the data transmission efficiency between the IoT terminals and the relay node device. The candidate IoT terminals satisfying the number are determined from the plurality of IoT terminals based on the distance information of each IoT terminal and the relay node device. Since the distance information is related to the channel delay and the channel quality signal to a certain extent, the IoT terminals are screened through the distance information, so that the pairing success rate of the selected candidate IoT terminals and the relay node device is higher, and the data transmission stability is also higher.

[0152] Optionally, in step S503, determining the number of IoT terminals currently allowed to be paired according to the capability information of the relay node device can include: determining the number of IoT terminals currently allowed to be paired by the relay node device according to the number of IoT terminals simultaneously allowed to be paired by the relay node device and the number of IoT terminals currently paired by the relay node device in the capability information of the relay node device.

[0153] Optionally, in step S504, a specific implementation of determining at least one candidate IoT terminal from the IoT terminals according to the number of IoT terminals required to be paired, the number of IoT terminals currently allowed to be paired, and the distance information of each IoT terminal and the relay node device can refer to steps S201-S203 and S301-S302.

[0154] Figure 6 Flowchart of the device pairing method provided in the embodiment Figure Six Optionally, in step S505, the node state detection result of the relay node device can include:

[0155] S601, if the node state detection of the relay node device is passed, a pairing request is sent to each candidate IoT terminal, and a pairing confirmation message sent by each candidate IoT terminal is received.

[0156] Optionally, the node state detection of the relay node device includes but is not limited to the following contents: the node has available idle channels; the node has idle computing power resources; the number of terminals connected by the node does not exceed the upper limit value. When the above three conditions are met, it is considered that the detection is passed, and then the relay node device can send a pairing request to each candidate IoT terminal and receive a pairing confirmation message sent by each candidate IoT terminal.

[0157] S602, if the node state detection of the relay node device fails, re-perform the node state detection after the timer expires, and send the pairing request to each candidate IoT terminal after the node state detection passes.

[0158] When one of the above three conditions is not met, it is considered that the detection fails. Then, the relay node device can re-perform the node state detection after the timer expires, and send the pairing request to each candidate IoT terminal after the detection passes.

[0159] In some embodiments, similarly, the relay node device can update the IoT terminals connected to the relay node device when a new IoT terminal is detected to be activated or an already connected IoT terminal is detected to be closed, so as to achieve the purpose of updating the candidate IoT terminals.

[0160] In an implementable manner, when the relay node device determines the candidate IoT terminals only according to the self-capability information, the candidate IoT terminal can perform re-judgment according to the self-capability information of the IoT terminal when receiving the pairing request sent by the relay node device. When the self-capability information also meets the requirements, the relay node device sends a pairing confirmation message to the relay node device, otherwise, a pairing failure message is sent.

[0161] In another implementable manner, when the relay node device determines the candidate IoT terminals according to both the self-capability information and the capability information of each IoT terminal, the candidate IoT terminal can no longer perform re-judgment when receiving the pairing request sent by the relay node device, but directly sends a pairing confirmation message to the relay node device.
