1. eSIM module and working principle developed at present
As shown in fig. 5, the eSIM ecosystem architecture (eSIM module) includes MNO (operator), CI digital signature authentication center, EUM (eSIM manufacturer), eSIM card, SM-DP (subscription data preparation), SM-SR (subscription data security routing), and the like, the SM-DP, MNO, SM-SR calls ES5, ES6, ES8 interface access through data SMs, BIP-CATTP, HTTPs transport layer protocol, and the eSIM performs PROFILE or application dynamic management. Specifically, each character is divided as follows:
CI: the CA center is responsible for issuing digital certificates and root certificate verification for MNOs, SM-DPs, SM-SRs and EUMs.
EUM: responsible for eSIM production, root certificate and EUM production certificate download, operator communication PRO-FILE initialization.
SM-DP: subscription data preparation is responsible for generating PROFILE and managing ISD-P card content in eSIM.

The eSIM switching strategy adopts a heartbeat-based switching algorithm to realize signal switching of three networks of China Mobile, china telecom and China Unicom, as shown in fig. 6, and the specific steps are as follows:
s1, after the module is electrified, uploading data through an eSIM module of the communication terminal every three minutes, namely acquiring terminal position information, terminal moving speed and terminal time information from an operation base station, and sending the terminal position information, the terminal moving speed and the terminal time information to an eSIM cloud management platform.
S2, the eSIM module reports information to the eSIM cloud management platform at regular time: terminal position information, terminal moving speed, terminal time information, base station signal strength, connection time extension, network operators and EID, ICCID, IMEI, and requests a new task, wherein the time interval duration is the duration of one heartbeat.
And S3, the eSIM cloud management platform performs network switching in the steps S4-S5 according to the specific switching strategy according to all the information reported in the step S2 and the system starting and running stages.
And S4, when the system is started, a three-network optimal selection strategy is mainly adopted to perform network selection and switching. The three-network optimal selection strategy is to select according to the communication network optimization index, wherein one index is whether the signal (signal strength) is optimal, the other index is whether the network delay is shortest, the third index is the lowest network cost, and an optimal network is selected after comparison.
1) Comparing signal quality: and if the signal strength of the current operator is lower than the first threshold value-110 dbm, switching the operation base station, judging the signal again until the signal strength is higher than the first threshold value, and using the operation base station.

2. At present, the main structure, the working principle and the working flow of the Beidou communication module are introduced.
The main components of the hardware are as follows:
the Beidou satellite receiving part: the Beidou satellite antenna receives signals, sends the signals to the Beidou signal receiving chip, namely the SoC chip in communication with the chip after demodulation, and then transmits data to the SoC BP (Baseband Processor) baseband processor part through the APB high-speed bus.
The big dipper signal receiving chip mainly comprises two parts:
SoC AP (Application Processor) application processor portion: ARM single core is used as CPU core, necessary peripheral equipment such as internal memory, NOR Flash external storage, clock signal and APB bus is connected with Beidou baseband.
SoC BP (Baseband Processor) baseband processor portion: the core Beidou SoC baseband processor obtains satellite navigation messages, outputs the satellite navigation messages to the SoC AP application processor, obtains terminal position information, terminal moving speed and terminal time information of the communication terminal through calculation, and sends the terminal position information, the terminal moving speed and the terminal time information to the IMX6 series main processor through the SoC AP application processor.
The main processor outputs: and transmitting terminal position information, terminal moving speed and terminal time information of the communication terminal to the eSIM cloud management platform.
The working principle is mainly described:
s1, if the eSIM module controlled by the main processor cannot acquire any communication signal of the operation base station, the main processor is informed to switch to the Beidou communication module.
S2, in the navigation and positioning process of the Beidou satellite to the communication terminal, the Beidou satellite only provides Beidou satellite observation information for the communication terminal, when the communication terminal of the user obtains the navigation message of the Beidou satellite, the communication terminal of the user can automatically perform data calculation and obtain a positioning result, and the calculation process for realizing positioning is completed by a main processor.
And in the PVT calculation process, the receiving communication terminal calculates satellite position coordinates of the observation time according to four satellite navigation messages, then calculates terminal position information and terminal time information of the current communication terminal according to the calculated satellite position coordinates and satellite pseudo-range measured values, and then calculates the terminal moving speed of a communication terminal receiver according to Doppler frequency shift. The basic calculation process is shown in fig. 7.
Algorithms for calculating terminal position information and terminal time information of a communication terminal generally employ a least square method and a kalman filter algorithm.
When the number of captured satellites is greater than 4, a group of calculated pseudo ranges, satellite positions and time correction values of all captured satellites are taken down, the pseudo ranges are corrected according to the time correction values, and the position of a user (communication terminal) is solved by using a least square method. A common solution for this procedure is a four-star-like positioning method, which is implemented by first applying the equation (1) to the pseudoranges ρ of n satellites j The method comprises the following steps:
T s for the system time of signal leaving satellite, T u For the system time of arrival of the signal at the user receiver, delta t For the deviation of the satellite clock relative to the system clock, t u For the deviation of the receiver clock from the system time c represents the speed of light. j=1, 2,3.
The following linearization method is adopted for the formula (1), so that the following steps are obtained:
in the formula (2), Δρ n Pseudo-range differential variable, deltax, representing user (communication terminal) u ，Δy u ，Δz u Representing three-dimensional coordinate differential variables of satellites, x being used for three-dimensional coordinates of jth satellite j ，y j ，z j (j=1, 2,3,) n represents Δt u A is a differential variable of the deviation of the receiver clock from the system time xj ，a yj And a zj The unit vector representing the cosine of the direction and pointing to the j satellite from the approximate user direction is expressed as a matrix:
the matrix of the formula (3) is expressed to obtain:
Its least squares solution is:
calculate Deltax u ，Δy u ，Δz u The position (terminal position information) x of the user can be obtained by the above formulas u ，y u ，z u And solving the clock difference t of the receiver according to the equation set u (deviation of the receiver clock from the system time). The condition for this calculation method is that Δx is required u ，Δy u ，Δz u Located near the linearization point.
From the calculus knowledge, the speed is the derivative of the user position with respect to time, i.e. the movement speed V of the user can be found by equation (6).
The calculation method given by the above formula needs to be satisfied at t 2 -t 1 During this time, the user keeps the running speed relatively constant, where u (t 1 ) Representing t 1 The position of the user at the moment, u (t 2 ) Representing t 2 The location of the user at the moment.
Thus, the P position (terminal position information), T clock (terminal time information), and V speed (terminal moving speed) of the communication terminal are calculated.
And S3, the communication terminal transmits the resolved terminal position information, terminal moving speed and terminal time information to the eSIM cloud management platform.
And S4, when the eSIM base station cannot communicate, the terminal position information, the terminal moving speed and the terminal time information which are solved by the communication terminal are sent to the Beidou satellite in a short message form, and then summarized data are sent to an eSIM cloud management platform, so that data transmission from the terminal to the cloud is realized.
S5, the main processor periodically detects the signal of the operation base station according to the time of 1 minute. And if the operation base station signal is detected, autonomously switching to the eSIM module. If the communication terminal is forcedly set to be in Beidou satellite communication, acquiring original information provided by the Beidou satellite according to a set period, sending calculated information to the Beidou satellite, and then transmitting the information to the eSIM cloud management platform by the Beidou satellite.
3. The main structure, working principle and working flow of the main processor and the WiFi and Bluetooth modules are introduced.
The main configuration of the host processor in communication with the WiFi and Bluetooth modules is shown in fig. 4.
The working principle is mainly described:
s1, the main processor detects whether a WiFi network which can be accessed exists around, and if so, auxiliary relative geographic position information (Assisted Position) which can be obtained through WiFi is sent to the eSIM cloud management platform.
S2, whether the WiFi network can be accessed or not, switching into the eSIM module, scanning the operation base station, and selecting a proper operation base station according to the strategy introduced by the eSIM module.
Meanwhile, the configuration of the communication terminal can also be carried out by utilizing the WiFi and Bluetooth modules through the mobile phone. The basic working principle is introduced as follows:
s1, whether the mobile phone and the communication terminal can communicate through Bluetooth protocol or WiFi protocol, if the communication can be connected, the mobile phone can configure the communication terminal through an applet or an App.
The configuration of the related parameters of the communication terminal mainly comprises the following steps: wiFi network parameter configuration, bluetooth network parameter configuration, network connection period parameter configuration of three operators, forced manual switching of the networks of the three operators, whether manual switching to a Beidou navigation network is performed, a Beidou short message sending enabling switch and a Beidou short message sending periodic parameter.
