[0036] Referring to Figure 1 , Figure 1 is a flowchart of a NB-IoT terminal remote upgrading method provided by an embodiment of the application. The NB-IoT terminal remote upgrading method of the embodiment of the application can be applied to a NB-IoT platform, for example, the NB-IoT terminal remote upgrading method can be implemented by a software program configured on the NB-IoT platform. As shown in Figure 1 , the method comprises the following steps S100-S150.

[0037] S100, obtaining a remote upgrading list corresponding to a NB-IoT terminal to be upgraded from an Internet of Things application, and extracting a plurality of terminal IDs from the remote upgrading list.

[0038] In the embodiment of the application, for the convenience of understanding, the NB-IoT platform is first explained and described, as shown in Figure 2 , the structure of the NB-IoT platform is shown in Figure 2 Figure 2 ​In the embodiment, the NB-IoT platform comprises a policy management module, a queue management module and a data collection module, wherein the policy management module is configured to maintain the preconfigured wireless signal strength level mapping table of the NB-IoT cell, the remote upgrade queue length mapping table, the cell flow control parameter and the remote upgrade queue trigger time mapping table, the remote upgrade in-out queue rule table and other policy information; the queue management module is in communication connection with the data collection module and the policy management module to interact, to obtain the state information of the data collection module and the policy information of the policy management module and to make a judgment, to manage and control the NB-IoT terminal remote upgrade queue of the cell, including the queue length, the trigger time and the remote upgrade queue; and the data collection module is configured to collect the information of the NB-IoT terminal remote upgrade list, the terminal ID, the cell ID, the service state, the power state, the resource space, the cell wireless signal strength level and the flow control.

[0039] Understandably, the user sends a remote upgrade request to the NB-IoT platform through the Internet of Things application, the NB-IoT platform receives the remote upgrade request, and the data collection module in the NB-IoT platform obtains the remote upgrade list corresponding to the NB-IoT terminal to be upgraded from the Internet of Things application, and extracts a plurality of terminal IDs from the remote upgrade list. Understandably, the terminal ID is the ID corresponding to the NB-IoT terminal to be upgraded.

[0040] S110, query a plurality of base station IDs corresponding to the plurality of terminal IDs, and form a remote upgrade initial queue according to the plurality of base station IDs.

[0041] In the embodiment, after the data collection module in the NB-IoT platform obtains the plurality of terminal IDs, it also queries a plurality of base station IDs corresponding to the plurality of terminal IDs, and the queue management module forms a remote upgrade initial queue according to the plurality of base station IDs.

[0042] S120, for each base station ID, obtain wireless signal coverage information corresponding to the base station ID, and determine the remote upgrade queue length of each cell corresponding to each base station ID according to the wireless signal coverage information, the preconfigured wireless signal level mapping table and the preconfigured remote upgrade queue length mapping table.

[0043] In this embodiment of the invention, for each base station ID, the data acquisition module acquires wireless signal coverage information corresponding to the base station ID, wherein the wireless signal coverage information includes a reference signal received power and a signal-to-noise ratio (SNR); the queue management module determines the wireless signal strength level of each cell corresponding to each base station ID based on the wireless signal coverage information and a pre-configured wireless signal level mapping table; specifically, if the reference signal received power is within a first preset received power range / a second preset received power range / a third preset received power range and the SNR is within a first preset SNR range / a second preset SNR range / a third preset SNR range, then the wireless signal strength level of each cell corresponding to each base station ID is set to a first level / a second level / a third level according to the pre-configured wireless signal level mapping table. More specifically, the pre-configured wireless signal strength level mapping table is as follows: Figure 3 As shown, in Figure 3 In this process, the platform and network sides collaborate to determine the signal strength level of each NB-IoT base station cell based on its reference signal received power and signal-to-noise ratio (SNR). The range of the reference signal received power and SNR is configured as needed by the platform and network sides in collaboration. Understandably, as... Figure 3 As shown, the first preset receiving power range, the second preset receiving power range, and the third preset receiving power range are [A1, 0], [A2, A1) and [A3, A2) respectively; the first preset interference-to-noise ratio range, the second preset interference-to-noise ratio range, and the third preset interference-to-noise ratio range are [B1, 0], [B2, B1) and [B3, B2) respectively; and the first level, the second level, and the third level are L1 level, L2 level, and L3 level respectively.

[0044] Furthermore, after determining the wireless signal strength level of each cell, the remote upgrade queue length of each cell is determined according to the wireless signal strength level of each cell and a pre-configured remote upgrade queue length mapping table. Specifically, for each cell, if the wireless signal strength level of the cell is the first level / second level / third level, then the remote upgrade queue length of the cell is set to the first length / second length / third length according to the pre-configured remote upgrade queue length mapping table. More specifically, as... Figure 4 As shown, Figure 4 For the pre-configured remote upgrade queue length mapping table, by Figure 4 It is known that the maximum number of terminals supported by the remote upgrade queue for each cell is determined based on the wireless signal strength level of each cell; that is, the maximum number of terminals is the length of the remote upgrade queue. The queue length supported by each wireless signal strength level is configured as needed by the platform and network sides in collaboration. Understandably, as...Figure 4 As shown, the remote upgrade queue lengths corresponding to the L1 level, the L2 level and the L3 level are C1, C2 and C3.

[0045] S130, acquiring flow control information corresponding to each of the cells, and adjusting the trigger time of the NB-IoT terminal in each of the cells according to the flow control information and the preconfigured remote upgrade queue trigger time mapping table.

[0046] In the embodiment of the application, after determining the remote upgrade queue length corresponding to each cell, the data acquisition module acquires flow control information corresponding to each of the cells, and the queue management module adjusts the trigger time of the NB-IoT terminal in each of the cells according to the flow control information and the preconfigured remote upgrade queue trigger time mapping table. Specifically, if the flow control information is the first preset flow control information / second preset flow control information, the trigger time of the NB-IoT terminal in each of the cells is set to increase the first preset delay time / second preset delay time according to the preconfigured remote upgrade queue trigger time mapping table. More specifically, as shown in the table, Figure 5 Figure 5 The remote upgrade queue trigger time mapping table is preconfigured, the remote upgrade queue trigger time refers to the time of triggering the terminal in the queue to start the upgrade process, if the detected flow control message is "SIB14 Access Barring", the trigger time is delayed by M seconds; if the detected flow control message is "OVERLOAD START" or "Back-off timer", the trigger time is randomly delayed by N seconds; wherein M and N are configured by the platform side and the network side as needed. Understandably, the first preset flow control information is "SIB14 Access Barring", and the second preset flow control information is "OVERLOAD START" or "Back-off timer"; the first preset delay time and the second preset delay time are M seconds and N seconds, respectively.

[0047] S140, acquiring state information of the NB-IoT terminal, and adjusting the in-out queue state of the NB-IoT terminal in each of the cells according to the state information and the preconfigured remote upgrade in-out queue rule table, to form a remote upgrade queue.

[0048] ​In the embodiment of the present application, after adjusting the triggering time of the NB-IoT terminal in each cell, the data acquisition module acquires the state information of the NB-IoT terminal, wherein the state information includes terminal service state, power state and resource space; the queue management module adjusts the in-out queue state of the NB-IoT terminal in each cell according to the state information and the preconfigured remote upgrade in-out queue rule table to form a remote upgrade queue. Specifically, if the terminal service state is in an idle state, the power state is in a preset power range, and the resource space is less than a preset resource space, the in-out queue state of the NB-IoT terminal in the cell corresponding to the state information is set to in according to the preconfigured remote upgrade in-out queue rule table. If the terminal service state is not in the idle state, the power state is not in the preset power range, and the resource space is not less than the preset resource space, the in-out queue state of the NB-IoT terminal in the cell corresponding to the state information is set to out according to the preconfigured remote upgrade in-out queue rule table. As shown in Figure 6 Figure 6 The remote upgrade in-out queue rule table is preconfigured, and Figure 6 in which, the NB-IoT terminal is determined to be in or out according to the terminal service state, the power state, the resource space and the like. If the terminal service state is in an idle state, the terminal power percentage is greater than P, and the terminal storage resource space is greater than S, the terminal is determined to be in, otherwise, the terminal is determined to be out; wherein P and S can be configured by the platform side or the customer as needed. It should be noted that if one of the three conditions that the terminal service state is not in an idle state, the terminal power percentage is not greater than P, and the terminal storage resource space is not greater than S is not met, the terminal is determined to be out.

[0049] S150, remotely upgrading the NB-IoT terminal according to the remote upgrade queue.

[0050] In the embodiment of the present application, the NB-IoT terminal is remotely upgraded according to the remote upgrade queue. It should be noted that the above-mentioned NB-IoT terminal remote upgrade is for the NB-IoT terminal after online, and for the NB-IoT terminal not online, the above-mentioned remote upgrade method will be automatically triggered after online. Understandably, according to the acquired wireless signal coverage information of the base station cell, the flow control message, the state information of the NB-IoT terminal and the preconfigured multiple mapping tables, the in-out queue state, the queue length and the triggering time of the NB-IoT terminal remote upgrade queue can be dynamically adjusted in real time, so as to dynamically adapt to the network load state and the terminal capability, improve the NB-IoT terminal remote upgrade success rate, reduce the remote upgrade retry times, and reduce the network congestion probability. ​

[0051] Figure 7 This is an application diagram illustrating a remote upgrade method for an NB-IoT terminal provided in an embodiment of the present invention, such as... Figure 7 As shown, Customer A needs to perform a batch firmware upgrade on 100,000 gas meters distributed in a densely populated residential area, with each upgrade package divided into 300 segments; Customer B needs to perform a batch software upgrade on 200,000 water meters distributed in the same area, with each upgrade package divided into 10 segments. Customers A and B submit their upgrade requests to the NB-IoT platform and can configure specific parameters of the remote upgrade queuing rules table through the platform's graphical interface, setting thresholds such as power consumption and resource space. After configuration, the NB-IoT platform aggregates customer requirements, forms a remote upgrade list for the corresponding residential area, and configures mapping table parameters such as remote upgrade queue length and trigger events according to the NB-IoT remote design method described above. The platform collects status information in real time through the data acquisition module, dynamically adjusting the remote upgrade queue based on the network-side status to form a remote upgrade queuing list, queue length, and random trigger time that matches the residential area, improving the success rate of remote upgrades and enhancing the customer experience.

[0052] In summary, this embodiment optimizes and improves the success rate of remote terminal upgrades by coordinating the NB-IoT platform, network, and terminal sides. Dynamic adjustment of the upgrade queue reduces the number of retries for remote NB-IoT terminal upgrades, lowering network congestion and creating a virtuous cycle. Multiple tables maintained by the policy management module, such as the wireless signal strength level mapping table, remote upgrade queue length mapping table, remote upgrade queue trigger time mapping table, and terminal remote upgrade queuing rules table, can be configured as needed, allowing customers to configure relevant parameters on the terminal side. Dynamic adjustment of the remote upgrade queue trigger time is achieved by randomly configuring discrete delays, further improving the chance of peak-shaving. Therefore, it can improve the success rate of large-scale, batch remote upgrades of massive numbers of NB-IoT terminals.
