Problems solved by technology
[0003] In view of the problems shown above, the present invention provides a remote upgrade method and system for NB-IoT equipment to solve the problem that the traditional OTA management background mentioned in the background technology has no method for concurrent OTA of a cell base station. The number of downloads is regulated, which will lead to too many OTA downloads of devices in the same base station, and the OTA function will fail due to concurrent congestion, which will cause NB-IoT terminal devices to download and upgrade firmware to timeout or fail, resulting in devices in the entire community due to the above The problem that OTA upgrades cannot be performed due to network congestion

Embodiment Construction
[0078] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.
[0079] The NB-IoT network has the characteristics of narrow bandwidth, slow speed, high connection, and high latency. In the OTA application scenario, when connected devices in the same community are concentrated in the same time period for OTA download and upgrade firmware, very high bandwidth will be required. , for NB-IoT terminal equipment, due to the mobility of equipment, the num...

The present invention discloses a remote upgrade method and system for NB-IoT devices, comprising: receiving a version detection request periodically sent by a target NB-IoT device, and confirming whether the target NB-IoT device has firmware according to the version detection request Update version, if it is confirmed that the target NB-IoT device has a firmware update version, obtain the target cell ID corresponding to the target NB-IoT device, and confirm whether the target NB-IoT device is allowed to download the firmware update version according to the number of device connections of the target cell ID. After the NB-IoT device downloads the firmware update version, it generates a target update report for the target NB-IoT device and stores it. The workload of the OTA server is reduced, and at the same time, the firmware update efficiency of other connected devices of the OTA server is improved, and the occurrence of NB‑IoT terminal devices downloading and upgrading firmware timeout or Failure and other problems ensure that each NB-IoT terminal device can download its own updated firmware, which greatly improves the practicability.
Description
technical field [0001] The present invention relates to the field of equipment upgrade technology, in particular to a remote upgrade method and system for NB-IoT equipment. Background technique [0002] The NB-IoT network has the characteristics of narrow bandwidth, slow speed, high connection, and high latency. In the OTA application scenario, when connected devices in the same community are concentrated in the same time period for OTA download and upgrade firmware, very high bandwidth will be required. , for NB-IoT terminal equipment, due to the mobility of equipment, the number of NB-IoT terminal equipment under the same cell base station is dynamic and shares bandwidth. When faced with the application of OTA upgrade package download, the traditional The OTA management background has no way to control the number of concurrent OTA downloads of a base station in a certain cell. This will cause too many OTA downloads of devices in the same base station, and the OTA function ...
