[0077] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

[0078] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, data stored, data displayed, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties. Furthermore, the collection, use and processing of the relevant data must comply with relevant laws, regulations and standards, and corresponding operation entry points are provided for users to choose to authorize or refuse.

[0079] It should be noted that in the embodiments of this application, certain software, components, models and other existing solutions in the industry may be mentioned. These should be regarded as exemplary and are only intended to illustrate the feasibility of implementing the technical solution of this application. However, it does not mean that the applicant has used or necessarily used the solution.

[0080] To facilitate understanding, the following will be combined with... Figure 1 The system architecture applicable to the embodiments of this application will be described.

[0081] Figure 1 This is a schematic diagram of the system architecture provided for an embodiment of this application. Please refer to [link / reference]. Figure 1It 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 can communicate at close range.

[0083] In practical applications, multiple mobile devices exist around the first mobile device 101. The server 104 can determine multiple trusted second mobile devices 102 that are close to the first mobile device 101 based on the device information of these multiple mobile devices. Then, the server 104 sends the device information of each second mobile device 102 to the first mobile device 101 via the wireless communication base station 103. Based on the device information of each second mobile device 102, the first mobile device 101 identifies the target mobile device among the second mobile devices 102 and establishes short-range communication with the target mobile device.

[0084] The first mobile device includes a location module, a communication module, a sensor module, and an interaction module, while 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 acquire information such as the device's location, the communication module can be used to send and receive data, the sensor module can be used for device detection and processing, and the interaction module can be used for short-range communication.

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

[0087] In related technologies, before establishing short-range communication, mobile devices need to send detection signals via sensors to detect nearby compatible mobile devices. Upon receiving a response signal from a compatible mobile device, the mobile device can establish a short-range communication connection, thus achieving short-range communication. However, in this process, the mobile device may need to send numerous detection signals to detect compatible mobile devices, and some of these compatible devices may be illegitimate, leading to wasted resources and reduced communication security.

[0088] To address the aforementioned technical problems, in this embodiment, when short-range communication is required, the first mobile device first sends a short-range communication request to the server. This request includes the location of the first mobile device and the communication purpose. After receiving device information from multiple second mobile devices sent by the server, the first mobile device, based on the communication purpose and this device information, detects the target mobile device using sensors and establishes a short-range communication connection with it to complete the short-range communication. During this process, the server can identify multiple trustworthy second mobile devices that are close to the first mobile device. Thus, the first mobile device can detect matching mobile devices by sending only a small number of detection signals, saving resources and improving communication security.

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

[0090] Figure 2 This is a flowchart illustrating a short-range communication method provided in an embodiment of this application. Please refer to... Figure 2 As shown, the method may include the following steps:

[0091] S201, Send a short-range communication request to the server.

[0092] The execution subject of this application embodiment can be a first mobile device or a near-field communication device installed in the first mobile device. The near-field communication device can be implemented by software or by a combination of software and hardware.

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

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

[0095] S202, Receive device information of multiple second mobile devices sent by the 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] Device information may include the device identifier and location of the second mobile device.

[0098] Equipment identification refers to the unique identifier assigned to equipment.

[0099] The server can determine multiple second mobile devices in the following way: The server obtains the locations of multiple mobile devices (which periodically report their locations to the server), and based on the location of each mobile device and the location of the first mobile device, determines candidate mobile devices from among these multiple mobile devices. The distance between the candidate mobile devices and the first mobile device is less than or equal to a preset distance. The server can also perform identity authentication processing on each candidate mobile device, obtain the identity authentication result of each candidate mobile device, and determine the candidate mobile device whose identity authentication result is successful as the second mobile device.

[0100] For example, assuming the preset distance is 200 meters, the distance between the device and the first mobile device is 150 meters, and the device's authentication result is successful, then the device can be identified as the second mobile device.

[0101] Optionally, device authentication can be performed using a preset model. For example, by inputting the device information obtained at the current moment into the preset model, the authentication result corresponding to that device information can be obtained.

[0102] The preset model can be obtained as follows: acquire authentication information of multiple devices within a historical period, including device information and identity authentication results; preprocess the authentication information, which may include cleaning, missing value imputation, outlier handling, etc.; use a feature extraction algorithm (e.g., principal component analysis) to extract relevant features from the authentication information and input them into a deep learning model (e.g., SiamRPN++ model) for training to obtain the preset model.

[0103] For example, suppose there are four mobile devices in the vicinity: Device 1, Device 2, Device 3, and Device 4. The preset distance is 80 meters. Specifically, 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 authentication result of Device 1 is unsuccessful, the authentication result of Device 2 is unsuccessful, the authentication result of Device 3 is successful, and the authentication result of Device 4 is successful. Then, the distances and authentication results between Device 1, Device 2, Device 3, and 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 authentication result of device 4 is passed, then device 4 can be identified as the second mobile device.

[0107] S203. Based on the device information and communication purpose of the multiple second mobile devices, device detection processing is performed using sensors in the first mobile device to detect the target mobile device among the multiple second mobile devices.

[0108] Sensors can send detection signals for device detection and processing. These sensors can be infrared sensors, ultrasonic sensors, and lidar sensors, among others.

[0109] The target mobile device can be detected in the following way: determine the detection direction based on the communication purpose; based on the detection direction, perform detection processing through sensors to obtain detection information, which includes the identifiers of multiple detection devices, and the detection devices are the mobile devices detected by the first mobile device; based on the device information of multiple second mobile devices and the detection information, determine the target mobile device among the multiple second mobile devices.

[0110] Optionally, if the purpose of communication is to transmit data, the detection direction is determined based on the positions of the second mobile devices and the first mobile device in the device information; if the purpose of communication is to avoid obstacles, the movement direction of the first mobile device is determined as the detection direction.

[0111] After determining the detection direction, the target mobile device can be identified as follows: obtain the device identifier of each second mobile device from the device information to obtain multiple second device identifiers; obtain the device identifier of each detection device from the detection information to obtain multiple detection device identifiers; identify the duplicate device identifiers among the multiple second device identifiers and multiple detection device identifiers as the target device identifier; identify the mobile device corresponding to the target device identifier as the target mobile device.

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

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

[0114] In practical applications, the first mobile device can send a short-range communication connection request to the target mobile device and establish a short-range communication connection with the target mobile device based on the short-range communication connection request.

[0115] The device information also includes key pairs. The server is also used to send key pairs to multiple secondary mobile devices.

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

[0117] Short-range communication with a target mobile device can be achieved as follows: Based on the purpose of communication, determine the target data to be transmitted to the target mobile device; encrypt the target data using the public key in the key pair to obtain encrypted data; send the encrypted data to the target mobile device so that the target mobile device can decrypt the encrypted data using the private key in the key pair.

[0118] If the purpose of communication is to transmit data, the target data includes: the location of the first mobile device, the identifier 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 includes: the location of the first mobile device, the identifier of the first mobile device, and the movement route of the first mobile device in the future.

[0119] In this embodiment, the first mobile device first sends a proximity communication request to the server. This request includes the location and communication purpose of the first mobile device. After receiving device information from multiple second mobile devices sent by the server, the server performs device detection processing based on the communication purpose and this device information to obtain the target mobile device. Then, a proximity communication connection is established with the target mobile device, enabling proximity communication between the mobile devices. In this process, the server can identify multiple trustworthy second mobile devices that are close to the first mobile device. Thus, the first mobile device can detect matching mobile devices by sending only a small number of detection signals, saving resources and improving communication security.

[0120] Figure 3 This is a schematic diagram illustrating the process of determining the target mobile device as provided in an embodiment of this application. Please refer to... Figure 3 The method may include the following steps:

[0121] S301. Obtain the location and communication purpose of the first mobile device, as well as device information of multiple second mobile devices.

[0122] The purposes of communication include: transmitting data and avoiding obstacles.

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

[0124] S302. Determine the detection direction based on the positions of each second mobile device and the first mobile device in the device information.

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

[0126] Among them, the number of 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 device corresponding to the detection direction and the first mobile device is less than or equal to a preset distance.

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

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

[0129] For example, assuming 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, and the distance between the first mobile device and the second mobile device 3 is 150 meters, 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 can be shown in Table 2:

[0130] Table 2

[0131]

[0132] According to Table 2, 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 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, execute S304.

[0134] S303. The direction of movement of the first mobile device is determined as the detection direction.

[0135] The direction of movement of the first mobile device can be obtained through sensors.

[0136] S304. Based on the detection direction, the sensor performs detection processing to obtain detection information.

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

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

[0139] S306. Obtain the device identifier of each detection device from the detection information to obtain multiple detection device identifiers.

[0140] S307. Among multiple second device identifiers and multiple detection device identifiers, the duplicate device identifiers are identified as the target device identifier.

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

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

[0143] In this embodiment, after obtaining the communication purpose of the first mobile device and the device information of multiple second mobile devices, a detection direction can be determined based on the communication purpose (data transmission and obstacle avoidance). Device detection processing is then performed based on the detection direction to obtain detection information, which includes multiple detection device identifiers. The second device identifiers in the device information are then compared with the detection device identifiers in the detection information. Duplicate device identifiers are identified as target device identifiers, and the mobile device corresponding to the target device identifier is identified as the target mobile device. In this process, when the communication purpose is data transmission, the detection direction can be determined based on the number of second mobile devices corresponding to the detection direction and their distance from the first mobile device. That is, a direction with many mobile devices and a short distance from the first mobile device is selected for detection, avoiding unnecessary detection in other directions, saving resources, and significantly reducing device detection time, thus improving detection efficiency.

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