This application is a Section 371 of International Application No. PCT/CN2018/115215, filed Nov. 13, 2018, which was published in the Chinese language on Jul. 4, 2019 under International Publication No. WO 2019/128501 A1, which claims priority under 35 U.S.C. § 119(b) to Chinese Patent Application No. 201711476183.4, filed Dec. 29, 2017, the disclosures of which are incorporated herein by reference.

FIELD

The present disclosure relates to communication technologies, and in particular, to an inter-vehicle wireless payment method based on a 5G communication network and a system for the same.

BACKGROUND

At present, Electronic Toll Collection (ETC) technology is widely used in highway scenarios, and it has been an on-board charging system largely promoted in Europe, America, Japan and China, wherein communication between an on-board electronic tag and a microwave antenna over an ETC-dedicated lane is realized via microwave-specific short-range communication technologies, and bank background settlement is achieved via Internet technologies.

An ETC charging system consists of a plurality of subsystems, including: an Automatic Vehicle Identification (AVI) system, an Automatic Vehicle Classification (AVC) system, a Video Enforcement System (VES) and other peripheral systems.

The Automatic Vehicle Classification (AVC) system determines the type of a passing vehicle via various sensor devices mounted in and around a lane and check it with the vehicle type data stored on an on-board unit (OBU). The Video Enforcement System (VES) is employed to take the image of the license plate of a vehicle having no valid on-board unit installed and rushing through the ETC lane, for determining a toll-evading vehicle owner and notifying the vehicle owner of the fee payable. For a high-speed ETC lane, the Video Enforcement System is indispensable. For a low-speed ETC lane, an automatic high-speed rail is often employed to force an illegal vehicle to stop.

The Automatic Vehicle Identification (AVI) system uses a microwave antenna mounted on a portal or on the roadside to inquire the identification information stored on the on-board unit, for example, information such as ID number of the on-board unit, vehicle type and vehicle owner, etc., to identify whether the vehicle is allowed to pass through the ETC lane. The AVI system is the fundamental system forming an ETC lane, and it often consists of an On-Board Unit (OBU), a RoadSide Unit (RSU), an on-board unit programmer and other devices.

The main problem of the current ETC payment lies in that an additional device needs to be mounted on a vehicle and there exists only a few application scenarios, mostly for highway toll station. For a user, a dedicated bank card needs to be applied for; and for a toll station, a dedicated communication device needs to be erected. More importantly, for the ETC technology, only the payment scenario of vehicles towards roadside devices has been considered, while the inter-vehicle payment scenario has not been considered or technically designed.
