and A30, if the primary terminal distance exceeds the preset stable communication distance, selecting the base station communication mode as the target communication mode.
In this embodiment, the base station-passing communication method is a method of completing communication using a base station as a communication medium, and the base station-passing communication method may be a 4G communication method or a 5G communication method. The communication mode of the base station is a mode of completing communication through an interface without passing through the base station. The communication mode of the base station can be a PC5 (C-V2X underlying direct connection cellular communication protocol) communication mode.
Exemplarily, the steps a10 to a30 include: acquiring a first quantity of the first communication terminal and a second quantity of the second communication terminal, taking a sum of the first quantity and the second quantity as the terminal quantity of each communication terminal, and if the terminal quantity does not exceed a preset quantity threshold, generating a primary terminal distance between the first communication terminal and the second communication terminal according to first position information and second position information corresponding to the first communication terminal in the team formation instruction; determining a preset stable communication distance capable of stably communicating when the communication mode of the non-excessive base station is used; judging whether the distance of the primary terminal exceeds the preset stable communication distance or not; if the primary terminal distance does not exceed the preset stable communication distance, selecting the non-excessive base station communication mode as the target communication mode; and if the primary terminal distance exceeds the preset stable communication distance, selecting the base station passing communication mode as the target communication mode.

It can be understood that the preset stable communication distance corresponding to the base station communication mode is long, but the cost is high, but the preset stable communication distance corresponding to the base station communication mode is relatively short, but the cost is low, so that the communication mode suitable for vehicle-mounted real-time communication adaptation between the first communication terminal and the second communication terminal is realized by judging the initial terminal distance between the first communication terminal and the second communication terminal, and the cost of the vehicle-mounted real-time communication is reduced on the premise of ensuring the stability of the vehicle-mounted real-time communication.
In step a30, after the step of selecting the past base station communication mode as the target communication mode if the initial terminal distance exceeds the preset stable communication distance, the method further includes:
step A40, determining an updated terminal distance between the first communication terminal and the second communication terminal and a hysteresis distance corresponding to the preset stable communication distance;
step A50, if the updated terminal distance exceeds a first distance, selecting the base station passing communication mode as the target communication mode, wherein the first distance is the sum of the preset stable communication distance and the hysteresis distance;
step A60, if the updated terminal distance does not reach a second distance, selecting the non-excessive base station communication mode as the target communication mode, wherein the second distance is a difference value between the preset stable communication distance and the hysteresis distance;
step a70, if the updated terminal distance reaches the second distance and does not exceed the first distance, keeping the target communication mode unchanged.
In this embodiment, the hysteresis distance is a floating distance corresponding to the preset stable communication distance that can be communicated in the base station communication method, and the hysteresis distance may be 100m or 50m.
Exemplarily, the step a40 to the step a70 include: when detecting that the first position information and/or the second position information changes, taking a distance difference value between first updated position information and second updated position information as an updated terminal distance between the first communication terminal and the second communication terminal, and acquiring a floating distance which can be communicated in the non-base station communication mode as a hysteresis distance corresponding to the preset stable communication distance; if the updated terminal distance exceeds a first distance, selecting the base station passing communication mode as the target communication mode; if the updated terminal distance does not reach a second distance, selecting the non-excessive base station communication mode as the target communication mode; if the updated terminal distance reaches the second distance and does not exceed the first distance, keeping the target communication mode corresponding to the primary terminal distance or the updated terminal distance unchanged; and returning to the execution step: and acquiring the updated terminal distance between the first communication terminal and the second communication terminal.
It can be understood that the target communication mode is selected only by presetting a stable communication distance, in an actual communication scene, the distance floating of the first communication terminal and the second communication terminal is uncertain, and the situation of frequently switching the communication modes is easy to occur, so that the situation that the vehicle-mounted real-time communication between the first communication terminal and the second communication terminal is unstable and low in efficiency is caused, the technical defect that the distance floating of a small base number causes the situation of frequently switching the communication modes is avoided by adding the hysteresis distance, and the stability and the efficiency of the vehicle-mounted real-time communication are improved.
In step S30, the step of selecting the target communication mode according to the team forming command and the second location information further includes:
step B10, if the number of the terminals exceeds a preset number threshold, generating each terminal distance between the communication terminals according to the first position information and the second position information;
step B20, judging whether the terminal distance between a first target communication terminal and each communication terminal in each communication terminal does not exceed the preset stable communication distance;
step B30, if the communication terminal exists, selecting a single communication mode as the target communication mode, wherein the single communication mode is that the same communication mode is adopted among all the communication terminals;
and step B40, if the target communication mode does not exist, selecting a hybrid communication mode as the target communication mode, wherein the hybrid communication mode is that at least two communication modes are adopted between the communication terminals.
Exemplarily, the steps B10 to B40 include: if the number of the terminals exceeds a preset number threshold, generating each terminal distance between the communication terminals according to the first position information of the first communication terminal and each second position information; judging whether the terminal distance between a first target communication terminal and each communication terminal does not exceed the preset stable communication distance or not in each communication terminal; if the terminal distance between a first target communication terminal and each communication terminal does not exceed the preset stable communication distance in each communication terminal, selecting a single communication mode as the target communication mode, wherein the communication modes between the communication terminals adopt the non-base station communication mode; and if the terminal distance between the first target communication terminal and each communication terminal does not exceed the preset stable communication distance in each communication terminal, selecting a hybrid communication mode as the target communication mode.
As an example, referring to fig. 2, fig. 2 illustrates the single communication mode, and fig. 2 includes: a first target communication terminal (illustrated interphone a), each of the communication terminals (illustrated interphones B and RSU), and a preset stable communication distance (illustrated S) corresponding to the target communication terminal 1 ) And a preset stable communication distance S corresponding to the RSU 3 . Selecting the single communication mode as the target communication mode because the terminal distance between the first target communication terminal and each communication terminal does not exceed the preset stable communication distance corresponding to each communication terminal, and enabling the interphones B and RSU to be respectively communicated with the first target through a base station-free modeThe communication terminals communicate, and thus, the interphone B and the RSU can indirectly communicate through the first target communication terminal.
In step B40, the selecting a hybrid communication method as the target communication method, where the hybrid communication method is a method in which at least two communication methods are used between the communication terminals, and the selecting the hybrid communication method includes:
a step B41 of determining, among the communication terminals, a second target communication terminal whose terminal distance to at least one short-range communication terminal does not exceed the preset stable communication distance;

and step B43, selecting the base station passing mode as a target communication mode between the second target communication terminal and a long-distance communication terminal, wherein the long-distance communication terminal is a communication terminal except for the second target communication terminal and the short-distance communication terminal.
Exemplarily, the steps B41 to B43 include: determining a second target communication terminal, among the communication terminals, which is not more than the preset stable communication distance from the terminal to at least one short-range communication terminal; selecting the base station non-passing mode as a target communication mode between the second target communication terminal and each short-distance communication terminal, wherein each short-distance communication terminal is communicated with the second target communication terminal through the base station non-passing mode; and selecting the base station passing mode as a target communication mode between the second target communication terminal and the long-distance communication terminal, wherein each long-distance communication terminal is communicated with the second target communication terminal through the base station passing mode.
Compared with a method for vehicle-mounted real-time communication in a full-duplex communication mode such as a radio station, social software or a telephone, a team forming instruction is generated and sent to a cloud server, so that the cloud server can obtain second position information corresponding to a second communication terminal according to the team forming instruction; if the position information sent by the cloud server is received, acquiring user interaction information, and encrypting the user interaction information to obtain an encrypted information frame; according to the formation instruction and the second position information, a target communication mode is selected, the encrypted information frame is sent to the second communication terminal according to the target communication mode, so that the second communication terminal can decrypt the encrypted information frame to obtain the user interaction information, the appropriate communication mode is matched in real time according to the formation instruction, and the private information interaction in the formation queue is realized, so that the technical defect that personal and private vehicle-mounted real-time communication cannot be realized due to the fact that most radio stations are public radio stations, or when the number of base stations between vehicles or vehicle roads is small or even no base station exists, the delay condition of the vehicle-mounted real-time communication is easy to occur is overcome, and the privacy and the high efficiency of the vehicle-mounted real-time communication are achieved.
