step S101: and acquiring the current network quality index of the LPWAN environment where the LPWAN terminal suitable for the air firmware upgrading is located.
Before executing step S101, it is first determined whether the LPWAN terminal is suitable for over-the-air firmware upgrade, that is, whether the LPWAN terminal is suitable for over-the-air firmware upgrade according to a traffic model of the LPWAN terminal. In specific implementation, according to a service model of the LPWAN terminal, determining that the LPWAN terminal is in an operating mode or a non-operating state, if the LPWAN terminal is determined to be in the operating mode, determining that the LPWAN terminal is an LPWAN terminal suitable for air firmware upgrade, and if the LPWAN terminal is determined to be in the non-operating mode, determining that the LPWAN terminal is an LPWAN terminal not suitable for air firmware upgrade.

And if the current network quality index reaches or exceeds a preset index threshold, determining that the LPWAN environment is suitable for air firmware upgrading. The current network quality index may be one or a combination of multiple indexes. The preset index threshold may be configured and issued by the FOTA server, or may be locally configured by the LPWAN terminal.

Namely, the firmware upgrade package is searched and downloaded only under the condition that the working mode is adopted and the current network quality index reaches the standard.
It should be noted that, during installation of the firmware upgrade package, if the LPWAN terminal is moved from the operating mode to the non-operating mode (i.e., is in the non-operating mode), or the LPWAN terminal is in the operating mode and the service of the current service cycle is not completed, the installation of the firmware upgrade package is stopped. Namely, the firmware upgrade package is only installed in the working mode and the current service cycle service is completed.
It will be understood by those skilled in the art that all or part of the steps in the method for implementing the above embodiments may be implemented by hardware related to instructions of a program, and the program may be stored in a computer readable storage medium.
Fig. 2 is a schematic diagram of an LPWAN network environment provided in the embodiment of the present disclosure, as shown in fig. 2, in the LPWAN network environment, a terminal of the internet of things (or an LPWAN terminal) collects data, and communicates with a service server through a cloud end by using a base station (or an LPWAN base station) supporting an LPWAN protocol. The firmware upgrading method comprises the steps that a firmware upgrading package of the terminal (or the LPWAN terminal) of the Internet of things is deployed in an FOTA server, the terminal (or the LPWAN terminal) of the Internet of things searches for the package and downloads the package from the FOTA server, and the firmware upgrading is completed after the firmware upgrading package is downloaded to the local. The service server and the FOTA server may be different servers or may be implemented on the same server.
Fig. 3 is a schematic structural diagram of an internet of things terminal (or LPWAN terminal) for LPWAN adaptive FOTA upgrade provided in an embodiment of the present disclosure, as shown in fig. 3, the internet of things terminal (or LPWAN terminal) includes 3 main modules in a FOTA service portion: the FOTA search and download module 51, the FOTA installation module 52 and the FOTA upgrade main control module (i.e. LPWAN FOTA main control module) 53.
The FOTA upgrade main control module 53 is a key module of the adaptive FOTA upgrade apparatus under the LPWAN, and determines whether to perform FOTA upgrade by detecting signal strength, signal-to-noise ratio, communication bandwidth (i.e., determining whether the LPWAN environment is suitable for firmware upgrade over the air) and/or an operation mode of the internet of things terminal (or LPWAN terminal) (i.e., determining whether the LPWAN terminal is suitable for firmware upgrade over the air) included in the current LPWAN environment. The FOTA upgrade main control module 53 communicates with the FOTA packet searching and downloading module 51 and the FOTA installation module 52, and controls the behaviors of the two modules.
The FOTA packet searching and downloading module 51 communicates with the FOTA server storing the firmware upgrade packet, completes packet searching and downloading of the over-the-air firmware upgrade packet, and stores the packet to the internet of things terminal (or LPWAN terminal).
The FOTA installation module 52 performs firmware local installation and update actions of FOTA.
Fig. 5 is a schematic diagram of a package searching and downloading process of adaptive FOTA upgrade under LPWAN according to an embodiment of the present disclosure, and as shown in fig. 5, the process may include the following steps:
step 701: and the server or the terminal initiates an upgrading process.
The FOTA upgrade can be initiated by the server or the device itself.
Step 702: the LPWAN FOTA upgrade main control module 53 is started.
When the FOTA upgrade is started, the device starts the LPWAN FOTA upgrade main control module 53 for managing and controlling the flow of FOTA upgrade in the LPWAN network.
The FOTA upgrade main control module 53 configures an index threshold of the LPWAN network environment where the FOTA upgrade process is located, where the index threshold may be one or a combination of some indexes, such as one or more of current signal strength, signal-to-noise ratio, and network transmission bandwidth.
The configuration of the index threshold is through a configuration file or other modes, a user can dynamically modify the configuration, and the configuration file can be issued through a server or locally dynamically modified.
The indicator threshold is used for describing the communication and transmission quality of the current LPWAN network, and when the indicator threshold is lower than the value, it indicates that the LPWAN environment where the terminal is located is not suitable for air firmware upgrade, that is, the network transmission quality where the terminal is located is poor, data transmission delay is high, and battery power consumption of the terminal is obviously increased. The FOTA packet searching and downloading upgrading operation needs to be stopped under the threshold.
Step 703: the FOTA upgrade master control module 53 determines whether the terminal is suitable for over-the-air firmware upgrade, if yes, step 704 is performed, otherwise, step 703 is performed.
The FOTA upgrade main control module 53 determines whether the terminal is in a working mode according to the service model of the terminal, if so, determines that the terminal is suitable for the air firmware upgrade, that is, the terminal is suitable for the air firmware upgrade, otherwise, determines that the terminal is not suitable for the air firmware upgrade, that is, the terminal is not suitable for the air firmware upgrade. That is to say, the LPWAN FOTA upgrade main control module 53 needs to determine the current working mode of the LPWAN terminal, fig. 4 is a schematic diagram illustrating a working mode conversion of the terminal of the internet of things under the LPWAN according to the embodiment of the present disclosure, and as shown in fig. 4, the terminal of the internet of things under the LPWAN determines the current working mode according to the set service model. For example, in the report of data read by a water meter in an NBIOT network, a common working service model is to report data once every 24 hours, a service Mode of the water meter is a reported time, for example, 10 minutes, a Mode of the terminal in the period of time is a working Mode (Work Mode), and the water meter is in a Sleep Mode (Sleep Mode) at the rest of the time. The LPWAN FOTA upgrade main control module 53 detects whether the current terminal is in a working mode, performs FOTA operation if the current terminal is in the working mode, and does not perform FOTA flow if the current terminal is in a sleep mode.
It should be noted that, in the stage of searching and downloading the package, the apparatus and method may utilize the service operating mode of the LPWAN terminal to perform the corresponding FOTA upgrade package searching and downloading process in the operating mode.
Step 704: the FOTA upgrade master control module 53 determines whether the LPWAN environment in which the terminal is located is suitable for over-the-air firmware upgrade, if yes, step 705 is performed, otherwise step 703 is performed.
When the terminal is in the working mode, the current network quality index is obtained, the actually obtained data of the LPWAN network is compared with the threshold (i.e. the threshold set in step 702) configured and set in the FOTA upgrade main control module 53, when the threshold is higher than the threshold, the current network environment is suitable for the air firmware upgrade, and at this time, the package search and download operation of the FOTA is started. When the current network environment is lower than the threshold, the current network environment is not suitable for the air firmware upgrading, and the packet searching and upgrading operation of the FOTA is not carried out at the moment, so that the phenomenon that the battery power of the terminal is excessively consumed, and the working life of the terminal is sharply reduced is prevented. The quality indexes of the current network environment can be signal strength, signal to noise ratio, current network data transmission bandwidth and any other indexes related to network transmission delay and rate, the indexes are related to the rate and delay of data transmission, the low data transmission rate can prolong the FOTA upgrade time of the terminal under the LPWAN network, increase the battery power of the terminal, and therefore the service life of the terminal is shortened. The detection of the threshold may be compared and judged according to one or a combination of several.
Step 705: the FOTA search and download module 51 is notified to start searching for a package.
When the obtained indexes of the network, such as the signal strength, the signal-to-noise ratio, the current transmission network threshold and the like, meet the configured threshold requirements, it indicates that the current network environment is suitable for the air firmware upgrade, the air firmware upgrade processing can be performed on the terminal, at this time, the FOTA packet searching and downloading module 51 is notified to work, and the packet searching process is started first.
Step 706: after the FOTA upgrade package is searched, the FOTA upgrade package is downloaded, and the FOTA upgrade package is downloaded to an upgrade package storage area in the device.
It should be noted that, because the index parameter of the network is dynamic and may change, in the packet searching and downloading process of FOTA upgrade, the LPWAN FOTA upgrade main control module 53 needs to detect the dynamically changing index at regular time, and if the dynamically changing index is lower than the threshold index required by FOTA upgrade, the FOTA upgrade is stopped. And if the index is recovered to be above the threshold, continuing the FOTA packet searching and downloading process, and stopping and recovering actions can set a time threshold, and if the index is reduced or the recovery time is longer than the time threshold, starting corresponding operations, so that the FOTA upgrading actions are prevented from being stopped and started too frequently due to the jitter of the network threshold index.
It should be noted that, during the searching and downloading of the firmware upgrade package, if the LPWAN terminal is shifted from the operating mode to the non-operating mode (i.e., the LPWAN terminal is a terminal unsuitable for over-the-air firmware upgrade at this time) or the network environment is unsuitable for over-the-air firmware upgrade, the searching and downloading of the firmware upgrade package is stopped. That is, the packet searching and downloading process of the FOTA upgrade packet is within the time period of the working mode of the LPWAN terminal, when the LPWAN is switched to the working mode and needs to be switched to the sleep mode at that time, the current packet searching and downloading process is stored in the current working state and is suspended, and the current packet searching and downloading process is continued when the LPWAN terminal enters the working mode next time. The obtained real-time LPWAN network parameters and the set index threshold still need to be detected according to the flow when FOTA upgrade packet searching or downloading is performed next time.
Step 707: and completing upgrading by the FOTA upgrading package.
It should be noted that, when the download of the FOTA upgrade package is completed, the download completion flag is set, and the lpwan ota installation module 52 is notified to perform detection.
Fig. 6 is a schematic diagram of an installation process of an adaptive FOTA upgrade in an LPWAN network, where as shown in fig. 6, the process may include the following steps:
step 801: the FOTA install module 52 determines whether the download of the FOTA upgrade package is completed, if so, executes step 802, otherwise, repeats the step.
The FOTA install module 52 of the present apparatus checks the flag indicating that the download of the FOTA upgrade package is completed, and confirms that the download of the FOTA upgrade package is completed.
Step 802: determining whether the LPWAN terminal in the working mode has completed the service of the current service period (i.e. the LPWAN terminal is not currently doing the service), if yes, executing step 803, otherwise, repeating the step.
The method comprises the steps that the current LPWAN terminal is in a working mode, after the service of the service period is completed, before the current LPWAN terminal enters a dormant mode, FOTA installation work is started, after the FOTA installation is completed, the device enters dormancy or carries out next service according to the service period, and service reporting which does not affect the LPWAN terminal is carried out to the maximum extent.
It should be noted that, during installation of the firmware upgrade package, if the LPWAN terminal is moved from an operating mode to a non-operating mode (i.e., is in a non-operating mode, such as a sleep mode), or the LPWAN terminal is in an operating mode and the traffic of the current traffic cycle is not completed, the installation of the firmware upgrade package is stopped.
Step 803: completing the FOTA firmware upgrade of the LPWAN terminal.
In the existing FOTA upgrading technology, the FOTA upgrading method of the LWM2M is an upgrading mode applied to an LPWAN network, and the FOTA upgrading is performed by using a UDP-based COAP upgrading packet mode in the method for obtaining the upgrading packet. At present, the LWM2M FOTA technology does not consider some characteristics of the actual operating environment of the LPWAN network, so that a large amount of battery power of LPWAN equipment is consumed in the LWM2M FOTA upgrading process, and the design service life of the equipment is greatly reduced. Namely, LWM2M FOTA is a current Internet of things terminal FOTA upgrade, but brings a large power consumption influence under the condition of dynamic change of a network environment, and the upgrading mode is not associated with an actual business working model. In one embodiment, because the network signal strength of the environment where the terminal of the internet of things works is poor, interference exists between signals among the terminals when the terminals are on the network simultaneously, the signal-to-noise ratio is low, and the like, considering that the signal strength difference of the terminal of the internet of things in the LPWAN network and interference data among the signals can cause great delay in sending and receiving data, the actual downloading rate is far less than the theoretical rate, and the FOTA upgrade package searching time and the upgrade package downloading time are long, the device and the method provided by the embodiment of the disclosure can detect the current network condition of the LPWAN on the basis of the existing FOTA technology, including network indexes such as the current signal strength, interference and bandwidth. And executing the FOTA process when the signal intensity, the signal-to-noise ratio and the bandwidth reach preset thresholds, and not performing FOTA upgrading operation when the signal intensity, the signal-to-noise ratio and the bandwidth are lower than the thresholds. Specifically, the package search and upgrade of FOTA upgrade are related to indexes of the LPWAN network, FOTA upgrade is executed when the network indexes are good (larger than a set threshold), and FOTA upgrade is not executed when the indexes are not good. For example, the signal strength (RSRP), the signal-to-noise ratio (SINR), and the network download rate, if the RSRP, the network download rate is higher than a certain threshold, the upgrade procedure is executed, and if the RSRP, the network download rate is lower than the certain threshold, the upgrade procedure is stopped. In another embodiment, considering the working period of the terminal service model, a large amount of time is in a dormant state or a shutdown state, and a small amount of time is in a working state, for example, data is reported once a day by a typical NB-IOT water meter reading service. The FOTA upgrading scheme of the embodiment of the disclosure is combined with the working mode of the service of the LPWAN, when the service is in the working mode, the FOTA upgrading process is performed, and when the service is in the dormant mode, the FOTA process is not performed, so that the power consumption is saved to the maximum extent. Specifically, after FOTA upgrade is started, according to the working mode and the service cycle of the LPWAN terminal, FOTA packet search and download are performed only when the terminal is in the working mode and performs networking service, and the terminal does not perform FOTA packet search and download in a non-working mode outside the service period alone. For example, NBIOT water meter needs to report meter reading data once in 24 hours, and the time for reporting data in each networking process is about 10 minutes. The service period of the water meter is 24 hours, the working mode time is 10 minutes, the rest time is a sleep mode, after the FOTA upgrading is started, the device detects whether the network index meets the upgrading condition according to the working mode of the service period in 10 minutes, and searches for the package and downloads after the network index meets the upgrading condition, and the sleep mode does not search for the package and downloads for the FOTA. The service model of the NB-IOT water meter reading is a typical case, and the actual service period can be configured differently. It should be noted that the FOTA installation is completed after the service reporting, and the FOTA installation does not affect the normal service reporting process basically. In the example of the water meter, the FOTA can be installed after the reporting of the working mode of the water meter is completed, and the normal reporting of the meter reading data of the water meter cannot be influenced by the device and the method.
Generally, the main function of the LPWAN is to complete data collection and reporting, and the design goal is to shorten the service time as much as possible, and most of the time is in a dormant state, so that the service life of the battery can be kept longer. Based on the goal, the power consumption brought by the FOTA service is reduced as much as possible, and the reporting of the service is not influenced as much as possible. The embodiment of the disclosure searches and downloads the FOTA upgrade package according to the working mode and the service period of the LPWAN terminal, and does not consume extra electric quantity. When packet searching and downloading are started, the index of the current network can be dynamically detected, and when the index is lower than a threshold, the FOTA packet searching and downloading can not be started in a working period. Because the service life of the battery is seriously influenced by the FOTA packet searching and downloading under the condition of poor network quality, in order to save the battery power of the terminal, the FOTA upgrading is executed and stopped under the condition of dynamic change of the network environment. After the FOTA upgrade package is downloaded, the FOTA installation is started after the current service is finished, and the normal data reporting service is not influenced as much as possible by giving priority to the service reporting work of the terminal.
The method and the device are suitable for the FOTA upgrading operation scene of the Internet of things terminal (or the LPWAN terminal) under the LPWAN, and can also be applied to the application scene issued by the configuration parameters of the low-power-consumption network terminal.
Fig. 7 is a schematic block diagram of an over-the-air firmware upgrading apparatus provided by an embodiment of the present disclosure, and as shown in fig. 7, the apparatus may include an obtaining module 21, a determining module 22, and an upgrading module 23, where the obtaining module 21 and the determining module 22 may implement the function of the FOTA upgrade main control module 53 in fig. 3, and the upgrading module 23 may implement the functions of the FOTA search and download module 51 and the FOTA installation module 52 in fig. 3.
The obtaining module 21 is configured to obtain a current network quality index of an LPWAN environment where a low power consumption wide area network LPWAN terminal suitable for air firmware upgrade is located.
The determining module 22 is configured to determine whether the LPWAN environment is suitable for over-the-air firmware upgrade according to a current network quality indicator of the LPWAN environment in which the LPWAN terminal is located. The determination module implements the function of step S102 described above.
In another embodiment, the determining module 22 is further configured to determine whether the LPWAN terminal suitable for the over-the-air firmware upgrade is an LPWAN terminal suitable for the over-the-air firmware upgrade according to a traffic model of the LPWAN terminal before acquiring a current network quality indicator of an LPWAN environment in which the LPWAN terminal suitable for the over-the-air firmware upgrade is located. That is, the determining module 22 determines whether the LPWAN terminal is in an operating mode according to a service model of the LPWAN terminal, and if the LPWAN terminal is determined to be in the operating mode, it is determined that the LPWAN terminal is an LPWAN terminal suitable for firmware upgrade over the air.
In this embodiment, if the current network quality indicator reaches or exceeds a preset indicator threshold, the determining module 22 determines that the LPWAN environment is suitable for over-the-air firmware upgrade, where the current network quality indicator is an indicator related to a current network transmission delay and rate, and includes at least one of a current signal strength, a signal-to-noise ratio, and a network transmission bandwidth.
The upgrade module 23 is configured to perform air firmware upgrade processing on the LPWAN terminal if it is determined that the LPWAN environment is suitable for air firmware upgrade.
In this embodiment, if it is determined that the LPWAN environment is suitable for over-the-air firmware upgrade, the upgrade module 23 searches and downloads a firmware upgrade package, and after the firmware upgrade package is downloaded, if the service of the current service period that the LPWAN terminal in the working mode has completed is completed, the firmware upgrade package is installed.
