Their purpose is only to illustrate the feasibility of implementing the technical solution of the present application, but it does not mean that the applicant has or will necessarily use the solution.

[0080] For ease of understanding, the following Figure 1 , the system architecture applicable to the embodiments of the present application is described.

[0081] Figure 1 This is a schematic diagram of the system architecture provided by the embodiment of this application. Figure 1, includes a first mobile device 101, a second mobile device 102, a wireless communication base station 103 and a server 104.

[0082] The first mobile device 101 and the second mobile device 102 may perform short distance communication.

[0083] In actual application, there are multiple mobile devices around the first mobile device 101. The server 104 can determine multiple second mobile devices 102 that are close to the first mobile device 101 and are trustworthy based on the device information of the multiple mobile devices, and then send the device information of each second mobile device 102 to the first mobile device 101 through the wireless communication base station 103. The first mobile device 101 determines the target mobile device among the second mobile devices 102 based on the device information of each second mobile device 102, and performs short-range communication with the target mobile device.

[0084] Among them, the first mobile device includes: a location module, a communication module, a sensor module and an interaction module, and the server includes a location module, a preprocessing module, a model training module and an identity authentication module.

[0085] In the first mobile device, the location module can be used to obtain information such as the device location, the communication module can be used to send and receive data, the sensor module can be used for device detection processing, and the interaction module can be used for short-range communication.

[0086] In the server, the location module can be used to obtain the device information of each mobile device, the preprocessing module can be used to preprocess the authentication information of the mobile device, the model training module can be used to generate a preset model, and the identity authentication module can obtain the corresponding identity authentication result of the mobile device through the preset model.

[0087] In the related art, before short-range communication is performed, the mobile device needs to send a detection signal through a sensor to detect the surrounding mobile devices that can be matched. After receiving the response signal sent by the matching mobile device, the mobile device can establish a short-range communication connection with it, thereby achieving short-range communication. However, in the above process, the mobile device may need to send more detection signals to detect the matching mobile device, and there may be illegal devices among the matching mobile devices, which not only leads to a waste of resources, but also reduces the security of communication.

[0088] In view of the above technical problems, in an embodiment of the present application, when short-distance communication is required, the first mobile device first sends a short-distance communication request to the server, and the short-distance communication request includes the location of the first mobile device and the purpose of communication. After receiving the device information of multiple second mobile devices sent by the server, the first mobile device detects the target mobile device through a sensor according to the purpose of communication and the device information, and completes the short-distance communication by establishing a short-distance communication connection with the target mobile device. In the above process, the server can determine multiple second mobile devices that are close to the first mobile device and are trustworthy. In this way, the first mobile device can detect matching mobile devices by sending a small amount of detection signals, which not only saves resources but also improves the security of communication.

[0089] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0090] Figure 2 A flowchart of a short-distance communication method provided in an embodiment of the present application. Figure 2 As shown, the method may include the following steps:

[0091] S201. Send a short distance communication request to a server.

[0092] The execution subject of the embodiment of the present application may be the first mobile device, or may be a short-distance communication device arranged in the first mobile device. The short-distance communication device may be implemented by software, or may be implemented by a combination of software and hardware.

[0093] The short-range communication request includes the location of the first mobile device and the communication purpose, and the communication purpose includes: transmitting data and avoiding obstacles.

[0094] The location of the first mobile device may be obtained through a Global Positioning System (GPS).

[0095] S202: Receive device information of multiple second mobile devices sent by a server.

[0096] The distance between the first mobile device and the second mobile device is less than or equal to a preset distance, and the second mobile device is a device that has passed identity authentication.

[0097] The device information may include a device identification and a location of the second mobile device.

[0098] A device ID is a unique identifier assigned to a device.

[0099] The server may determine the multiple second mobile devices in the following manner: the server obtains the locations of the multiple mobile devices (the multiple mobile devices periodically report their locations to the server), and determines a mobile device to be selected from the multiple mobile devices according to the location of each mobile device and the location of the first mobile device, wherein the distance between the mobile device to be selected and the first mobile device is less than or equal to the preset distance. The server may also perform identity authentication processing on each mobile device to be selected, obtain an identity authentication result for each mobile device to be selected, and determine the mobile device to be selected whose identity authentication result is that the mobile device passed the identity authentication as the second mobile device.

[0100] For example, assuming that the preset distance is 200 meters, the distance between the device and the first mobile device is 150 meters, and the identity authentication result of the device is passed, the device can be determined as the second mobile device.

[0101] Optionally, the device may be authenticated using a preset model. For example, the device information currently acquired may be input into a preset model to obtain an authentication result corresponding to the device information.

[0102] The preset model can be obtained in the following way: obtaining authentication information of multiple devices in a historical period, the authentication information including device information and identity authentication results; preprocessing the authentication information, which may include cleaning, missing value filling, outlier processing, etc.; using a feature extraction algorithm (for example, principal component analysis) to extract relevant features from the authentication information, and inputting them into a deep learning model (for example, SiamRPN++ model) for training to obtain the preset model.

[0103] For example, assuming that there are 4 mobile devices around, namely, device 1, device 2, device 3 and device 4, and the preset distance is 80 meters, wherein the distance between device 1 and the first mobile device is 60 meters, the distance between device 2 and the first mobile device is 120 meters, the distance between device 3 and the first mobile device is 100 meters, and the distance between device 4 and the first mobile device is 50 meters. The identity authentication result of device 1 is failed, the identity authentication result of device 2 is failed, the identity authentication result of device 3 is passed, and the identity authentication result of device 4 is passed. Then, the distances and identity authentication results between device 1, device 2, device 3, device 4 and the first mobile device can be shown in Table 1:

[0104] Table 1

[0105]

[0106] According to Table 1, if the distance between device 4 and the first mobile device (50 meters) is less than the preset distance (80 meters), and the identity authentication result of device 4 is passed, device 4 can be confirmed as the second mobile device.

[0107] S203: Perform device detection processing through a sensor in the first mobile device according to device information and communication purposes of the plurality of second mobile devices, so as to detect and obtain a target mobile device among the plurality of second mobile devices.

[0108] The detection signal can be sent by the sensor to perform device detection processing. The sensor can be an infrared sensor, an ultrasonic sensor, a lidar sensor, etc.

[0109] The target mobile device can be detected in the following manner: determine the detection direction according to the communication purpose; perform detection processing through a sensor according to the detection direction to obtain detection information, wherein the detection information includes identifications of multiple detection devices, and the detection device is a mobile device detected by a first mobile device; determine the target mobile device among multiple second mobile devices according to device information of multiple second mobile devices and the detection information.

[0110] Optionally, if the purpose of communication is to transmit data, the detection direction is determined according to the position of each second mobile device in the device information and the position of the first mobile device; if the purpose of communication is to avoid obstacles, the moving direction of the first mobile device is determined as the detection direction.

[0111] After determining the detection direction, the target mobile device can be determined in the following manner: obtain the device identification of each second mobile device in the device information to obtain multiple second device identifications; obtain the device identification of each detection device in the detection information to obtain multiple detection device identifications; determine the repeated device identification among the multiple second device identifications and the multiple detection device identifications as the target device identification; determine the mobile device corresponding to the target device identification as the target mobile device.

[0112] For example, assuming that there are 5 second device identifiers in the device information, 10 detection device identifiers in the detection information, and there are 3 repeated device identifiers in the second device identifiers and the detection device identifiers, then the 3 repeated device identifiers can be determined as target device identifiers, and the second mobile devices corresponding to these three target device identifiers can be determined as target mobile devices.

[0113] S204: Establish a short-range communication connection with the target mobile device, and perform short-range communication with the target mobile device according to the communication purpose.

[0114] In actual application, the first mobile device may send a short distance communication connection request to the target mobile device, and establish a short distance communication connection with the target mobile device according to the short distance communication connection request.

[0115] The device information also includes a key pair. The server is also used to send the key pair to multiple second mobile devices.

[0116] Optionally, when the server sends the device information to the first mobile device, it may send the key pair to the second mobile device. For example, the server sends the identifier of the first mobile device and the key pair to the second mobile device.

[0117] Close range communication with a target mobile device can be performed in the following manner: according to the purpose of communication, target data to be transmitted to the target mobile device is determined; the target data is encrypted using the public key in the key pair to obtain encrypted data; the encrypted data is sent to the target mobile device so that the target mobile device decrypts the encrypted data using the private key in the key pair.

[0118] If the purpose of communication is to transmit data, the target data is determined to include: the location of the first mobile device, the identification of the first mobile device, and the data to be transmitted by the first mobile device; if the purpose of communication is to avoid obstacles, the target data is determined to include: the location of the first mobile device, the identification of the first mobile device, and the movement route of the first mobile device in the future time period.

[0119] In the embodiment of the present application, the first mobile device first sends a short-distance communication request to the server, and the short-distance communication request includes the location and communication purpose of the first mobile device. After receiving the device information of multiple second mobile devices sent by the server, the device detection process is performed according to the communication purpose and the device information to obtain the target mobile device, and then a short-distance communication connection is established with the target mobile device to achieve short-distance communication between mobile devices. In the above process, the server can determine multiple second mobile devices that are close to the first mobile device and are trustworthy. In this way, the first mobile device can detect matching mobile devices by sending a small amount of detection signals, which not only saves resources but also improves the security of communication.

[0120] Figure 3 Schematic diagram of the process of determining the target mobile device provided in the embodiment of the present application. Figure 3 , the method may include the following steps:

[0121] S301: Acquire the location and communication purpose of a first mobile device, and device information of a plurality of second mobile devices.

[0122] Among them, the communication purposes include: transmitting data and avoiding obstacles.

[0123] After S301, if the purpose of communication is to transmit data, S302 is executed; if the purpose of communication is to avoid obstacles, S303 is executed.

[0124] S302: Determine a detection direction according to the position of each second mobile device and the position of the first mobile device in the device information.

[0125] The detection direction can be determined in the following manner: determine the distance between the first mobile device and each second mobile device based on the position of each second mobile device and the position of the first mobile device in the device information; determine the second mobile devices corresponding to multiple preset directions based on the positions of each second mobile device; determine the detection direction among multiple preset directions based on the distance between the first mobile device and each second mobile device, and the second mobile device corresponding to each preset direction.

[0126] The number of the second mobile devices corresponding to the detection direction is greater than or equal to a preset threshold, and / or the average distance between the second mobile devices corresponding to the detection direction and the first mobile devices is less than or equal to a preset distance.

[0127] The preset direction refers to the connection direction between the first mobile device and the second mobile device.

[0128] The average distance refers to the average value of the distances between each second mobile device and the first mobile device in the same detection direction.

[0129] For example, assuming that the preset threshold is 1, the preset distance is 200 meters, the distance between the first mobile device and the second mobile device 1 is 100 meters, the preset direction is preset direction 1, the distance between the first mobile device and the second mobile device 2 is 200 meters, the preset direction is preset direction 1, the distance between the first mobile device and the second mobile device 3 is 150 meters, and the preset direction is preset direction 2, then the distances and preset directions of the second mobile device 1, the second mobile device 2, and the second mobile device 3 may be as shown in Table 2:

[0130] Table 2

[0131]

[0132] According to Table 2, it can be obtained that the second mobile device 1 and the second mobile device 2 are in the same preset direction (preset direction 1), that is, the number of second mobile devices corresponding to the preset direction 1 is 2, which is greater than the preset threshold (1), and / or, the average distance between the first mobile device and the second mobile device 1 and the second mobile device 2 (150 meters) is less than the preset distance (200 meters), then the preset direction 1 can be determined as the detection direction.

[0133] After S302, S304 is executed.

[0134] S303: Determine the moving direction of the first mobile device as the detection direction.

[0135] The moving direction of the first mobile device may be acquired through a sensor.

[0136] S304: Perform detection processing through sensors according to the detection direction to obtain detection information.

[0137] The detection information includes identifiers of multiple detection devices, and the detection devices are mobile devices detected by the first mobile device.

[0138] S305: Obtain a device identifier of each second mobile device from the device information to obtain a plurality of second device identifiers.

[0139] S306: Obtain a device identification of each detection device from the detection information to obtain multiple detection device identifications.

[0140] S307: Determine a repeated device identifier among the multiple second device identifiers and the multiple detection device identifiers as a target device identifier.

[0141] S308: Determine the mobile device corresponding to the target device identifier as the target mobile device.

[0142] It should be noted that the execution process of the above S305-S308 can refer to S203 and will not be repeated here.

[0143] In the embodiment of the present application, after obtaining the communication purpose of the first mobile device and the device information of multiple second mobile devices, the detection direction can be determined according to the communication purpose (transmitting data and avoiding obstacles), and the device detection processing can be performed according to the detection direction to obtain the detection information, which includes multiple detection device identifiers. Then, the second device identifier in the device information is compared with the detection device identifier in the detection information, and the repeated device identifier is determined as the target device identifier, and the mobile device corresponding to the target device identifier is determined as the target mobile device. In the above process, when the communication purpose is to transmit data, the detection direction can be determined according to the number of second mobile devices corresponding to the detection direction and the distance between them and the first mobile device, that is, a direction with more mobile devices and a shorter distance from the first mobile device is selected for detection, so as to avoid detection in unnecessary directions and save resources. Furthermore, the time for device detection is greatly reduced, and the detection efficiency is improved.

[0144] Based on any of the above embodiments, Figure 4 , the interaction process between the first mobile device, the second mobile device and the server is described in detail.
