[0130] As shown in FIG1 a , a communication system 100 includes a first terminal 101 and a second terminal 102 ;

[0131] In some embodiments, the communication system 100 may further include a network device, which may be an access network device or a core network device.

In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0135] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0136] In some embodiments, the core network device may be a single device including a first network element, or may be a plurality of devices or a group of devices, each including a first network element. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0137] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0138] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1a, or a portion thereof, but are not limited thereto. The entities shown in FIG1a are illustrative only. The communication system may include all or a portion of the entities shown in FIG1a, or may include other entities other than those shown in FIG1a. The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0139] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0140] In some embodiments, driven by the increasing demand for speed, latency, high-speed mobility, and energy efficiency, coupled with the increasing diversity and complexity of future services, fifth-generation mobile communication technology (5G) has been introduced. The primary application scenarios for 5G are: enhanced mobile ultra-broadband (eMBB), ultra-reliable and low-latency communications (URLLC), and massive machine-type communications (mMTC). eMBB continues to focus on providing users with multimedia content, services, and data, and demand for it is growing rapidly. Furthermore, since eMBB can be deployed in diverse scenarios, such as indoors, in urban areas, and in rural areas, its capabilities and requirements vary significantly, making a blanket statement impossible. Detailed analysis is required based on specific deployment scenarios. Typical applications of URLLC include industrial automation, power automation, remote medical operations (surgery), and traffic safety. mMTC's key features include high connection density, low data volumes, latency-insensitive services, low module costs, and a long service life.

[0141] In some embodiments, ranging may be performed based on a received signal strength indication (RSSI) of the Bluetooth protocol.

[0142] In some embodiments, the vehicle-mounted terminal broadcasts signals periodically based on the Bluetooth protocol, and the mobile phone scans the broadcast signals; after the mobile phone scans that the vehicle-mounted terminal is within the communication range, it sends a Bluetooth connection request to the vehicle-mounted terminal and completes the Bluetooth connection with the vehicle-mounted terminal.

[0143] In some embodiments, the mobile phone and the vehicle-mounted terminal exchange information to establish a secure channel, and complete the identity confirmation of the mobile phone and the vehicle-mounted terminal within the secure channel.

[0144] In some embodiments, the mobile phone broadcasts a Bluetooth signal while maintaining a Bluetooth connection. The primary anchor point (which may be a vehicle-mounted terminal) and the secondary anchor point (which may be a vehicle-mounted terminal) on the vehicle receive the Bluetooth signal and measure the RSSI value of the broadcast signal.

[0145] In some embodiments, the vehicle terminal completes ranging based on the RSSI values ​​calculated by each anchor point and the mapping between RSSI and distance.

[0146] In some embodiments, the distance and the rate of change of the distance are used to determine whether the mobile phone is close to or far away from the car, thereby achieving contactless unlocking or locking.

[0147] In some embodiments, RSSI attenuates as distance increases. A preset mapping between attenuation and distance allows for stable distance measurement. However, because Bluetooth signals are susceptible to environmental interference (e.g., shielding, obstruction, and reflection), RSSI can fluctuate significantly.

[0148] In some embodiments, when the mobile phone is stationary relative to the vehicle body, even though it is not moving closer to or farther away from the vehicle, the RSSI fluctuates greatly, causing the calculated distance to fluctuate greatly, thus causing the vehicle to frequently switch between unlocked and locked states.

[0149] In some embodiments, a series of digital filtering techniques are used to smooth out RSSI fluctuations. However, filtering parameters are difficult to adapt to all usage scenarios, and RSSI smoothing inevitably causes system lag, resulting in a poor experience in seamless unlocking.
