Description

FIELD



[0001] 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



[0002] 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.

[0003] 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 (YES) and other peripheral systems.

[0004] 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 (YES) 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.

[0005] 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.

[0006] 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.

DETAILED DESCRIPTION



[0031] Some of the embodiments of the disclosure will be introduced below for providing a basic understanding of the disclosure, rather than confirming a key or crucial element of the disclosure or limiting the protection scope of the disclosure.

[0032] First, several concepts to be mentioned in the disclosure will be illustrated.
  1. 1) 5G (the Fifth Generation Mobile Communication Standard): it is also referred to as the fifth generation mobile communication technology, 5G for short, which is an extension of 4G, and the theoretical downlink speed of a 5G network is 10Gb/s (corresponding to a download speed of 1.25GB/s).
  2. 2) MEC (Mobile Edge Computing): mobile edge computing provides an IT service environment and a cloud computing ability in an RAN (Radio Access Network) nearest to a user mobile terminal, for further reducing delay/time delay, improving network operation efficiency, improving business distribution/delivery capacity and optimizing/improving end user experience. Thus, the "Edge" here refers to the mobile communication base station per se (eNodeB and RNC, etc.) and various servers in a wireless network (for example, sink node deployed therein). A mobile edge computing server deployed at the edge of a radio access network opens real-time wireless and network information (for example, real-time specific position of a user in a mobile state, and real-time load condition of a base station, etc.) to various upper applications and services, so as to provide various situation-related services.
  3. 3) D2D (Device-to-Device): it refers to Device-to-Device, D2D for short. Device-to-Device communication is a novel technology that allows terminals to communicate directly by multiplexing cell resources under the control of a system, thereby solving the problem of lack of spectrum resources of a wireless communication system to a certain extent. D2D technology may be applied to a mobile cellular network to improve resource utilization and network capacity. The resource occupied by each D2D communication link is equal to that occupied by a cellular communication link. D2D communication may obtain the frequency resource and transmission power required for communication, under the control of a macro cellular base station.


[0033] First of all, an inter-vehicle wireless payment method based on a 5G communication network according to the first embodiment of the disclosure will be illustrated.

[0034] Fig.1 is a flowchart showing an inter-vehicle wireless payment method based on a 5G communication network according to the first embodiment of the disclosure.

[0035] As shown in Fig.1, the inter-vehicle wireless payment method based on a 5G communication network according to the first embodiment of the disclosure includes:

a request sending step S100, in which a requesting vehicle sends a payment request to a base station;

a request-based retrieving step S200, in which the base station retrieves a vehicle information of a friend vehicle of the requesting vehicle based on the payment request;

an encrypting step S300, in which the base station encrypts a payment request information using the vehicle information of the friend vehicle;

a broadcasting step S400, in which the base station broadcasts the encrypted payment request information;

a decrypting and receiving step S500, in which at least one vehicle within a broadcast coverage of the base station attempts to decrypt the broadcasted payment request information using its respective vehicle information, and if one of the at least one vehicle decrypts the broadcasted payment request information successfully, the one of the at least one vehicle, that is the friend vehicle, acts as a responding vehicle and acquires the payment request information;

a payment implementation step S600, in which the responding vehicle generates a payment information based on the payment request information and sends the payment information to the base station, the base station sends the payment information to a payment platform, and the payment platform returns a payment result to the responding vehicle; and

a D2D communication step S700, in which the base station allocates a D2D communication channel to the requesting vehicle and the responding vehicle, and the responding vehicle and the requesting vehicle communicate with each other via the D2D communication channel.



[0036] In a certain embodiment, VIN is employed as the vehicle information.

[0037] Next, an inter-vehicle wireless payment system based on a 5G communication network according to the first embodiment of the disclosure will be illustrated.

[0038] Fig.2 is a block diagram showing a structure of an inter-vehicle wireless payment system based on a 5G communication network according to the first embodiment of the disclosure.

[0039] As shown in Fig.2, the inter-vehicle wireless payment system based on a 5G communication network according to the first embodiment of the disclosure includes a first on-board terminal 100 provided on a requesting vehicle, a base station 200, a second on-board terminal 300 provided on a responding vehicle and a payment platform 400.

[0040] The first on-board terminal 100 is configured to: perform 5G communication with the base station 200; generate a payment request and send it to the base station 200; and perform D2D communication with the second on-board terminal 300.

[0041] The base station 200 is configured to: retrieve driver information of the requesting vehicle and a vehicle information of a friend vehicle of the requesting vehicle based on the vehicle information of the requesting vehicle contained in the payment request; encrypt a payment request information using the vehicle information of the friend vehicle and broadcast the encrypted payment request information; and send a payment information to the payment platform upon receiving the payment information from the second on-board terminal 300; additionally, the base station 300 is configured to allocate a D2D communication channel to the requesting vehicle 200 and the second on-board terminal 300 as the responding vehicle.

[0042] The second on-board terminal 300 is configured to: perform 5G communication with the base station 200; decrypt the broadcasted payment request information using the vehicle information of the responding vehicle to acquire the above payment request information; generate the payment information based on the payment request information and send the payment information to the base station 200; and perform D2D communication with the first on-board terminal 100.

[0043] The payment platform 400 is configured to accomplish payment based on the payment information and return a payment result to the second on-board terminal 300 as the responding vehicle.

[0044] In a certain embodiment, the first on-board terminal 100 includes: a first GPS module 110 configured to acquire clock information to keep in synchronization with the base station 200, and establish an uplink and a downlink; a first 5G communication module 120 configured to implement 5G communication with the base station 200 and implement D2D communication with the second on-board terminal; and a first payment module 130 configured to generate the payment request. In a certain embodiment, the second on-board terminal 300 includes: a decryption module 310 configured to decrypt the encrypted payment request information broadcasted by the base station 200 using the vehicle information of the responding vehicle; a second payment module 320 configured to generate the payment information based on the decrypted payment request information; a second GPS module 330 configured to acquire clock information to keep in synchronization with the base station 200, and establish an uplink and a downlink; and a second 5G communication module 340 configured to implement 5G communication with the base station 200 and implement D2D communication with the first on-board terminal.

[0045] Theoretically, the first on-board terminal 100 and the second on-board terminal 300 may be configured with the same function, while the above description only refines their respective detailed functions.

[0046] In a certain embodiment, the base station 200 includes: a communication module 210 configured to communicate with the first on-board terminal 100 and the second on-board terminal 300 respectively; a core network 220 configured to store vehicle-related information, for example, the driver information and the VIN of the vehicle, and friend information of the vehicle driver, etc.; a mobile edge computing module 230 configured to retrieve the driver information of the requesting vehicle and the vehicle information of the friend vehicle thereof from the vehicle-related information stored in the core network 220 based on the vehicle information of the requesting vehicle contained in the payment request, and encrypt the payment request information using the vehicle information of the friend vehicle; a broadcasting module 240 configured to broadcast the encrypted payment request information; a payment module 250 configured to send the payment information to the payment platform 400 upon receiving the payment information from the second on-board terminal 300; and a D2D establishing module 260 configured to allocate the D2D communication channel to the requesting vehicle and the responding vehicle.

[0047] Next, one example of the inter-vehicle wireless payment method based on a 5G communication network according to the first embodiment of the disclosure will be illustrated.

[0048] This example shows an on-board payment method by which wireless payment is directly implemented between vehicles based on the D2D technology in a 5G communication system. This method is applicable to a scenario in which a vehicle finds that, when performing on-board payment, the account balance is not enough to pay the current fee (e.g., toll) and needs to loan money from other vehicles. In this case, for making a compromise between the practicability and allsidedness of the method, the banks of the vehicle user and the lender are allowed to be different, thus a third-party platform (which is referred to as payment platform here) is introduced in the method for accomplishing interbank transaction.

[0049] Furthermore, for easy description, each vehicle is in a normal-speed driving state or in a stationary state, that is, the driving speed is lower than 60km/h, thereby ensuring that the D2D communication is able to be established between vehicles. The D2D communication is under the control of the base station, and both of the vehicles of the two parties meet the requirements of D2D communication, that is, the path loss from the sending end to the receiving end is less than a certain threshold TH1 (of which the value is associated with the geographic environment of the vehicle), and the received signal strength of the receiving end is larger than a certain threshold TH2 (of which the value is associated with the geographic environment of the vehicle). The on-board terminal of the vehicle updates the GPS data at a fixed frequency (for example, 1 Hz, which is concerned with the GPS type). At the same time, the payment bank card bond to the current vehicle (i.e., the "requesting vehicle") and the payment bank card bond to the friend vehicle are from different banks, and a payment platform is employed for realizing interbank transaction.

[0050] The inter-vehicle wireless payment method based on a 5G communication network according to this embodiment includes the following steps:
  1. 1) the current vehicle starts, and the first on-board terminal 100 works, wherein the first on-board terminal includes a first GPS module 110, a first communication module 120 and a first payment module 130. By the first GPS module 110, the current vehicle may acquire the clock information to keep in synchronization with the base station 200 and establish an uplink communication link and a downlink communication link. The current vehicle may further obtain its own motion state information and position information via the first GPS module 110, wherein the motion state information and the position information respectively refer to the speed and acceleration of the current vehicle and the latitude and longitude of the vehicle, and such information may help the on-board terminal more accurately screen the payment scenario-related information.
  2. 2) The first on-board terminal 100 of the current vehicle sends the vehicle identification number (VIN) to the base station 200 via the uplink, and the base station 200 loads the basic information of the current vehicle into a mobile edge computing (MEC) module 230 of the base station 200 by accessing the core network 220, wherein the information includes related information such as friend information of the current vehicle and credit rating of the current vehicle;
  3. 3) When the first on-board terminal 100 detects that the current vehicle is in an idling state, the vehicle enters step 4); otherwise, it continues to perform the detection step.
  4. 4) The payment module 130 of the first on-board terminal 100 generalizes the payment request message received previously, pushes it to an on-board display screen, to prompt the user to pay. If the user account balance is enough for the current payment, it performs payment and returns step 3); otherwise, it performs step 5);
  5. 5) The current vehicle sends information such as the VIN and the required amount to the base station 200. Since the payment request message received by the current vehicle is a generalized message, there may exist a plurality of payees, thus in order to lower data transmission volume and ensure information security of the current vehicle, real-time transaction between the current vehicle and the friend vehicle is employed in this method, and the payment to the payee is accomplished by the current vehicle.
  6. 6) The base station 200 transfers such information to the mobile edge computing module 230, and the mobile edge computing module 230 extracts the friend information according to the VIN, then accomplishes the search of the friend vehicle of the current vehicle according to the VIN, and then performs information encryption using the VIN of the friend vehicle, wherein the information to be encrypted is the VIN of the current vehicle, the driver information of the current vehicle and the required amount of the current vehicle;
  7. 7) The broadcasting module 240 broadcasts the information encrypted by the mobile edge computing module 230, and the second on-board terminal 300 provided on the vehicle (i.e., the responding vehicle) receiving the broadcasted information attempts to decrypt using its own VIN, and if the information cannot be decrypted successful, it will be discarded. If the information can be decrypted successfully, the second on-board terminal 300 displays the loan information on an on-board display screen, wherein the loan information includes, for example, the driver information of the current vehicle and the required amount of the current vehicle.
  8. 8) If the user decides to lend to the current vehicle, the second payment module 320 of the second on-board terminal 300 of the responding vehicle performs payment, specifically, it pays the requested amount to the current vehicle. The second 5G communication module 340 of the responding vehicle sends grant information to the base station 200 via the uplink, wherein the grant information includes a grant flag, VIN of the responding vehicle, VIN of the current vehicle and payment amount, etc. If the base station does not receive the grant information within a set time, it enters step 12).
  9. 9) After the base station 200 receives and parses the grant information, it performs two operation: starting to establish a D2D connection between the current vehicle and the responding vehicle, that is, entering step 10); finding the account information used by the current vehicle and the account information used by the responding vehicle via the mobile edge computing module 230 using the VIN of the current vehicle and the VIN of the responding vehicle, packaging the two pieces of account information and the payment amount information and uploading it to the payment platform 400, and accomplishing inter-bank transfer with the aid of the payment platform 400, that is, entering step 11).
  10. 10) The D2D establishing module 260 of the base station 200 detects that the source vehicle and the destination vehicle are in the same cell or in adjacent cells, and determines according to a strategy with a maximum number of allowed D2D connections whether a D2D connection therebetween can be established. If it is determined that the D2D connection can be established, the base station 200 allocates resources to the D2D connection and establishes a link for the D2D connection; otherwise, it enters a waiting state.
  11. 11) The payment platform 400 parses the information received and informs the payer bank, i.e., the bank of the account used by the responding vehicle, to subtract the corresponding amount from the corresponding account. At the same time, it informs the payee bank, i.e., the bank of the account used by the current vehicle, to add the corresponding amount to the corresponding account. After the payment platform 400 receives a success feedback from the payer bank and a success feedback from the payee bank, it sends success information of the current payment to the second on-board terminal 300 of the responding vehicle via the base station 200.
  12. 12) A D2D link is established between the requesting vehicle and the responding vehicle thereof, and after the responding vehicle receives the payment success information forwarded by the base station 200, the responding vehicle (i.e., the second on-board terminal 300) sends the account identification number of its own vehicle to the current vehicle (i.e., the first on-board terminal 100), and the first on-board terminal 100 stores this information into non-accomplished payment, which will be uniformly pushed in the next payment information. The current vehicle sends the repayment proposal information as set by the user to the responding vehicle, wherein the information includes related information such as specific repayment time and repayment mode, etc. If the responding vehicle receives and accepts the proposal, it sends accept information to the current vehicle, which indicates that an agreement is reached.
  13. 13) After the transaction and the agreement are accomplished, the first on-board terminal 100 and the second on-board terminal 300 notify the base station 200 via the uplink that the D2D link is disconnected and resources are released.
  14. 14) The base station 200 notifies the current vehicle via the downlink that no friend vehicle responds to the request. If the current vehicle selects to initiate a request to a strange vehicle (that is, not a friend vehicle), the base station performs information broadcasting, wherein the information includes request VIN, account identification number used by the vehicle and requested amount, then it enters step 8). If the current vehicle selects to give up, it enters step 3) and waits for the next payment request message push.


[0051] In the case of selecting to loan from a strange vehicle, for example, the method further includes the following features: the information encryption key is a uniformly set key, for example, initially set as: 'rent', which is the information shared by all vehicles, and all vehicles may decrypt the information encrypted with 'rent' as a key; it may be preset for a vehicle whether to lend money to a strange vehicle, if it is set to 'no', the vehicle does not use 'rent' to decrypt the information, and the loan information from a strange vehicle may be regarded as irrelevant information and be discarded; if it is set to 'yes', the vehicle may decrypt the loan information from a strange vehicle, and the push flow is consistent with that in which it loans money from a friend vehicle; for repayment, in this system, the payment platform 400 is set as being able to issue an electronic loan statement for being used for related affairs.
