Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto.
Fig. 1 shows a flowchart corresponding to a program upgrading method for a narrowband internet of things NB-IOT device provided in an embodiment of the present invention, and as shown in fig. 1, the method includes:
step S101, NB-IOT equipment sends current software version information of the NB-IOT equipment to a server;
step S102, a server receives current software version information sent by the NB-IOT equipment and sends an upgrading instruction to the NB-IOT equipment according to the current software version information of the NB-IOT equipment;
s103, the NB-IOT equipment receives an upgrade instruction sent by the server;
step S104, the NB-IOT equipment determines whether to carry out program upgrading according to the attribute information of the upgrading file and the hardware state of the NB-IOT equipment;
step S105: and if the NB-IOT equipment determines to carry out program upgrading, sending an upgrading request to the server and receiving the upgrading file sent by the server.
In the embodiment of the invention, NB-IOT equipment sends current software version information to a server and receives an upgrading instruction sent by the server, the NB-IOT equipment determines whether to carry out program upgrading according to attribute information of an upgrading file in the upgrading instruction and the hardware state of the NB-IOT equipment, and if the NB-IOT equipment determines to carry out program upgrading, the NB-IOT equipment sends an upgrading request to the server and receives the upgrading file sent by the server. Therefore, the NB-IOT equipment can jointly judge whether to carry out program upgrading according to the received attribute information of the upgrading file and the hardware state of the NB-IOT equipment, so that the problem that the upgrading fails due to the fact that the server cannot know the hardware state of the NB-IOT equipment and actively carries out the program upgrading on the NB-IOT equipment can be avoided, and the efficiency of the program upgrading is effectively improved.
Specifically, in step S101, the NB-IOT device may send the current software version information to the server in various manners, for example, the NB-IOT device may send the current software version information at power-on start, or may send the current software version information at connection with the server, or may send the current software version information to the server periodically according to a set period, or may send the current software version information to the server when performing data communication with the server, which is not limited in this embodiment of the invention.
In step S102, the server receives the current software version information sent by the NB-IOT device, and determines whether to perform program upgrade on the NB-IOT device according to the current software version information of the NB-IOT device and an OTA (over the air) policy stored in the server.
In the embodiment of the present invention, the OTA policy stored in the server refers to a principle that the server upgrades the programs of the NB-IOT devices connected thereto, where software version information of the programs to which the NB-IOT devices are to be upgraded is specified. The specific content of the OTA policy may be determined by a person skilled in the art according to actual needs, for example, the OTA policy may be that all NB-IOT devices need to be upgraded to the latest software version, and the server determines to perform program upgrade on a certain NB-IOT device when the current software version information sent by the NB-IOT device is not the latest software version. For another example, the OTA policy is that the software versions of all NB-IOT devices are unified, and the server determines to perform program upgrade on a certain NB-IOT device when determining that the current software version information sent by the NB-IOT device is not the same as the software versions of most NB-IOT devices.
And if the server determines to perform program upgrading on the NB-IOT equipment, sending an upgrading instruction to the NB-IOT equipment. The upgrade indication includes attribute information of the upgrade file, where the attribute information may specifically include information such as size and type of the upgrade file. In this embodiment of the present invention, the type of the upgrade file may be any one or more of a protocol core, an application core, and a firmware core, which is not specifically limited in this embodiment of the present invention.
In step S103 and step S104, the NB-IOT device receives the upgrade instruction sent by the server, and determines whether to perform program upgrade according to the attribute information of the upgrade file in the upgrade instruction and the hardware state of the NB-IOT device itself.
In the embodiment of the invention, after receiving the upgrade instruction sent by the server, the NB-IOT equipment determines the current hardware state of the NB-IOT equipment, wherein the hardware state can specifically refer to the currently available memory space and storage space of the NB-IOT equipment.
According to the attribute information of the upgrade file, if the NB-IOT device determines that the current hardware state of the NB-IOT device can support the program upgrade, and if the memory space and the storage space can normally receive and store the upgrade file, the NB-IOT device sends an upgrade request to the server, so that the server sends the upgrade file to the NB-IOT device in step S105 after receiving the upgrade request.
After step S105, the NB-IOT device performs program upgrade according to the upgrade file after receiving the upgrade file, and feeds back a confirmation message indicating that upgrade is successful to the server after successful upgrade.
Therefore, compared with the method that the server actively sends the upgrade file to the NB-IOT equipment and performs the program upgrade under the condition that the hardware state of the NB-IOT equipment cannot be known in the prior art, the method has the advantages that the NB-IOT equipment has the initiative for whether the program upgrade is performed or not in the implementation of the method, and the NB-IOT equipment sends the upgrade request to the server only when the hardware state of the NB-IOT equipment is determined to support the program upgrade, so that the problem that the program upgrade fails due to insufficient memory or storage space of the NB-IOT equipment is effectively avoided, and the efficiency of the program upgrade is effectively improved.
It should be noted that, in step S105, before the NB-IOT device sends the upgrade request to the server, the NB-IOT device may further determine whether to perform fragmentation processing on the upgrade file according to the attribute information of the upgrade file and the current hardware state.
For example, if the upgrade file is large, the server sends the entire upgrade file to the NB-IOT device at one time, and the NB-IOT device may select to fragment the upgrade file when the memory or storage space of the NB-IOT device is not enough to receive the entire upgrade file. For another example, if the current network state is poor, when the server sends the whole upgrade file to the NB-IOT device at one time, the probability that the file needs to be retransmitted due to an error in the file transmission process is high, and in the severe case, even if the file needs to be retransmitted for many times, the upgrade file cannot be successfully received finally, and due to the fact that the transmitted data volume is increased, the NB-IOT device can select to perform fragmentation processing in such a case, so that the power consumption of the NB-IOT device and the probability of an error in the file transmission process are reduced.
And if the NB-IOT equipment determines to perform the fragment processing, an upgrading strategy for performing the fragment processing on the upgrading file is formulated, and the upgrading strategy is sent to the server through an upgrading request. In the embodiment of the present invention, the upgrade strategy formulated by the NB-IOT device specifically includes the number of fragments for fragmenting the upgrade file, and the identifier and size of each fragment.
Thus, after receiving an upgrade request sent by the NB-IOT device, the server may perform fragmentation processing on the upgrade file according to the upgrade policy in the upgrade request, divide the upgrade file into a plurality of fragments, and send a confirmation message indicating that the fragmentation processing is completed to the NB-IOT device, so as to notify that the preparation work before the NB-IOT device is upgraded is completed.
Furthermore, the NB-IOT device may pull each fragment from the server according to information of each fragment divided from the upgrade file in its own upgrade policy, and specifically includes:
and aiming at any fragment obtained by dividing the upgrade file, the NB-IOT equipment sends a fragment request message to the server, wherein the fragment request message comprises the identifier of any fragment. And the server receives a fragmentation request message sent by the NB-IOT equipment, and sends the fragmentation corresponding to the identification of any fragmentation to the NB-IOT equipment according to the identification of any fragmentation.
Therefore, in the embodiment of the present invention, after determining to perform program upgrade, the NB-IOT device may further formulate an upgrade policy for performing fragment processing according to the attribute information of the upgrade file and the current hardware state of the NB-IOT device, so that the server divides the upgrade file into a plurality of fragments, and performs independent transmission on each fragment. The server does not need to transmit the whole upgrade file to the NB-IOT equipment at one time, so that the possibility that the transmission process of the upgrade file is wrong, the upgrade file needs to be continuously retransmitted and the program upgrade is finally failed due to overlarge upgrade file is avoided, and the program upgrade efficiency is effectively improved. In addition, only one fragment is transmitted between the server and the NB-IOT equipment at a time, and compared with the whole upgrade file, the data volume of the fragment file is smaller, so that the power consumption of the NB-IOT equipment is reduced, and the performance of the NB-IOT equipment is not influenced in the transmission process of the upgrade file.
In step S104, since the hardware state (i.e., the memory space and/or the storage space) of the NB-IOT device may be dynamically changed, once the NB-IOT device triggers a timer in the NB-IOT device according to the attribute information of the upgrade file and the current hardware state, if it is determined that the program upgrade is not performed. When the next state of the timer comes, judging whether the hardware state can support the program upgrading again according to the attribute information of the upgrading file and the hardware state of the NB-IOT equipment, and if the upgrading is determined, sending an upgrading request to the server.
In the embodiment of the present invention, the duration of the set period in the timer may be set by a person skilled in the art according to actual needs, and the present invention is not limited to this specifically.
