It should be noted that the internet of things card for identifying the identity of the user by the soft card (vUICC) can be considered, the most important is to identify who uses the number and match with the corresponding service package, and the soft card itself has no communication function and needs to be used in cooperation with a communication module of the internet of things device. The communication module is a core component in the Internet of things equipment, can convert data into a signal capable of being transmitted, and transmits the signal out through a wireless network; data transmission and interconnection can be realized only by the communication module, and the communication module is a communication basis of the Internet of things equipment. At present, a communication module in the internet of things device has the characteristic of small integrated circuit volume, and according to different categories such as 2G, 3G, 4G, 5G, NB-IoT, WiFi, bluetooth and the like of a network, a baseband chip, a data processing chip, a soft card, an antenna and other micro circuits are integrated on the communication module.
It can be understood that the soft card that starts the communication module in the internet of things device can perform network identification on the user identity in the operator network, and if the soft card contains SIM card data (data such as network access permission and authentication key) required for establishing an initialization connection with the operator network, the communication module of the internet of things device can access the operator network and establish an initialization connection with the operator network. The initialization connection here means that the device is allowed to access the network but is not yet able to access the network and perform data transceiving.
In this embodiment, the operator network may be an entity that performs network operation and provides services; the network operator needs to know not only the network operation status from the network perspective but also the network operation status from the service perspective and can effectively utilize the network resources when providing multimedia services and applications. For example, a china telecommunication network, a china mobile network, and a china unicom network can be used as the operator network.
And step S200, acquiring a service code number from a preset service platform through the operator network, writing the service code number into the soft card, and starting the communication module to receive and transmit service data with the operator network according to the service code number written in the soft card.
In this embodiment, after the internet of things device successfully establishes the initial connection with the operator network, the service data may be received and transmitted only by acquiring the corresponding service code number from the service platform. For example, the internet of things device accesses a preset service platform through an operator network, and obtains a service code number from the service platform, wherein the service code number includes SIM card data required for receiving and transmitting service data; and writing the acquired service code number into a soft card of the communication module, and transmitting and receiving service data between the Internet of things equipment and the operator network according to the service code number written in the soft card.
It should be noted that the service platform may be used by a device manufacturer or a device operator to manage a network server of the internet of things device, and has functions of ordering a firmware upgrade package, a network communication package, and allocating a service number for the internet of things device. For example, the service platform may be a network server for manufacturers of smart homes, a network server for manufacturers of intelligent transportation, a network server for manufacturers of intelligent medical care, and the like.
Step S300, accessing a preset firmware server by using an operator network, obtaining a latest firmware version of the communication module from the firmware server, and performing FOTA upgrade on the communication module.
In this embodiment, the firmware server may be set in the cloud and perform data interaction with the internet of things device through the operator network, different firmware upgrade versions of the communication module may be configured in the firmware server in advance, and the firmware upgrade version is selected reasonably according to the upgrade requirement of the communication module in the internet of things device, and preferably, the latest firmware version of the communication module is obtained from the firmware server to perform FOTA upgrade on the communication module.
In one embodiment, the firmware server may be an OTA server, and the OTA server is capable of implementing a firmware management function for remotely managing the internet of things device through an air interface of the mobile communication and providing a firmware upgrade service of the communication module. By applying The OTA (over The air) technology, The mobile communication can not only provide simple voice, text, picture and video services, but also provide services for downloading The firmware, so that The service content is not limited by a platform, and more personalized data service types close to The requirements of users are continuously developed. Through OTA over-the-air download technology, the Internet of things equipment can quickly download the latest firmware version of the communication module to the local so as to upgrade and install the firmware.
It should be noted that FOTA (Firmware Over-The-Air) refers to a cloud upgrading mode for downloading Firmware Over The Air of a terminal device, and an internet of things device acquires an intelligent terminal system upgrading package by using a network according to needs and an easy-to-expand mode, and performs cloud upgrading through FOTA to complete system repair and optimization. The essence of FOTA is firmware upgrade, including upgrade of driver, system, function, application, etc., and has no direct relation with hardware, the applicable terminal range is very wide, and basically, the FOTA can provide upgrade service for all terminals in the market, and no matter for network operators or terminal equipment manufacturers, the terminal upgrade requirements of a large number of users can be processed at the same time through cluster application, grid technology and distributed service terminals.
In this embodiment, referring to fig. 2, the step S100 described above mainly relates to a process of starting a soft card and establishing an initialization connection with an operator network, and the step may specifically include steps S110 to S120, which are respectively described below.
And S110, the Internet of things equipment writes the preset seed code number into a soft card of the communication module and performs network registration on the soft card.
The seed code number here includes SIM card data required for establishing an initialization connection with an operator network, for example, includes authentication data required for establishing an initialization connection, and specific content and data format may be different for different operators or different communication protocols, so the application does not limit the specific content and data format of the seed code number. In one embodiment, the preset seed code number may include: public Land Mobile Network (PLMN), International Mobile Subscriber Identity (IMSI), Integrated Circuit Card Identity (ICCID), authentication Key (KI), Operator root Key (OP), and so on.
And step S120, the Internet of things equipment sets a network access point name according to the seed code number in the soft card, and establishes initialization connection with the operator network by using the network access point name.
In a specific embodiment, an Agent process (Agent) is set to implement intelligent connection management, bridging a server and a terminal, and then the Agent may obtain a seed code number (Profile) by parsing a Shared file (Shared Profile), and write the seed code number (Profile) into a soft card by means of a Local seed code number Assistant (LPA for short) to perform network registration; then, the Agent sets a network Access Point Name (APN) to establish an initialization connection with the operator network.
Those skilled in the art can understand that starting the soft card to establish initial connection with the operator network can make full use of the soft card function built in the communication module in the internet of things device before leaving the factory, and access the operator network through the self-contained connection service, so as to provide convenience for the communication module to access the internet of things.
In this embodiment, referring to fig. 3, the step S200 mainly involves starting a process of the communication module to transmit and receive service data to and from the operator network by using a service code number written in the soft card, and the step may specifically include steps S210 to S230, which are respectively described as follows.
Step S210, the internet of things device accesses a preset service platform through an operator network to obtain a service activation code. The service platform may be configured with a Subscription management Data Preparation server (SMDP +) for preparing a service code number.
Specifically, the service platform can be arranged at a cloud end and performs data interaction with the internet of things device through an operator network. Then, when the internet of things device accesses the service platform, the SMDP + first prepares a service Activation Code (AC) and sends it to the Agent in the internet of things device.
Step S220, the internet of things device downloads a corresponding service code number from the subscription management data preparation server by using the service activation code, and writes the service code number into the soft card. The service code number here includes SIM card data required for communication with the operator network to transmit and receive service data.
Specifically, the Agent in the internet of things device downloads the allocated service code number from the SMDP + according to the service AC by means of the LPA, and further, the Agent writes the downloaded service code number into the soft card through the LPA.
Step S230, the internet of things device starts the communication module according to the service code number written in the soft card to establish communication connection with the operator network, and then performs service data transceiving with the operator network.
Specifically, since the service code number includes SIM card data (such as networking key, package service, etc.) required for communicating with the operator network to receive and transmit the service data, the Agent in the internet of things device can read the service code number written in the soft card to start the communication module to smoothly network, thereby realizing the receiving and transmitting operation of the service data.
Those skilled in the art can understand that the service code number is acquired from the service platform through the operator network, and the data transceiving function of the communication module is started through writing the soft card, so that the communication module in the internet of things equipment can normally access the operator network, and service data is transceived with the operator network, thereby facilitating the subsequent module firmware version upgrading through the operator network.
In this embodiment, referring to fig. 3, the step S300 mainly relates to a process of obtaining the latest firmware version of the communication module from the firmware server and performing FOTA upgrade on the communication module, and the step may specifically include steps S310 to S320, which are respectively described as follows.
Step S310, the internet of things device uploads the current firmware version number of the communication module to a preset firmware server by using the operator network. The firmware server is used for storing and managing different firmware versions of the communication module in the Internet of things equipment.
It should be noted that when a communication module in the internet of things device needs to perform network system upgrade or multimedia service upgrade, the firmware version of the communication module needs to be upgraded to obtain the update service. After the current firmware version of the communication module is uploaded to the firmware server, the firmware server analyzes the current firmware version and matches the latest firmware version number.
Step S320, the internet of things device obtains a download link of the latest firmware version number from the firmware server, and downloads the upgrade package corresponding to the latest firmware version number by using the download link.
Step S330, the Internet of things equipment locally releases the upgrade package to carry out FOTA upgrade on the communication module. It should be noted that after the upgrade package corresponding to the latest firmware version number is downloaded to the internet of things device, the installation can be completed through links such as verification and release.
Those skilled in the art can understand that the firmware server can uniformly manage the firmware version of the communication module by accessing the firmware server to obtain the latest firmware version of the communication module and perform FOTA upgrade on the communication module, so that the communication module in the internet of things device can quickly download the latest firmware version in the firmware server through an operator network and automatically upgrade to a customized version.
