Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, in particular to a unicast interactive service processing method, a road side unit, a vehicle-mounted unit and a system. BACKGROUND

[0002] Near field payment service realizes vehicle-mounted payment function under the condition of ensuring payment security through data interaction between vehicle-mounted equipment unit and road side facility unit. According to different security mechanisms, near field payment is divided into two main processes: under the symmetric key security mechanism based on electronic toll collection (ETC), the near field payment service interaction process is divided into five main stages of unicast interaction link establishment, toll information acquisition, pass certificate acquisition, user prompt and link release. Under the certificate security mechanism based on long term evolution-vehicle to everything (LTE-V2X), toll information acquisition and unicast interaction link establishment are combined to complete. The current unicast interaction process, after the road side unit (RSU) and the vehicle-mounted unit (OBU) complete a unicast interaction, the RSU sends a link release message to the OBU to end the current unicast toll process. However, since the road service table (RST) sent by the RSU is still periodically and continuously sent, even after the OBU ends the current unicast toll process, the OBU will still receive the announcement message and further perform the subsequent interaction process. At this time, repeated interaction will occur, resulting in repeated billing or data interaction abnormalities, so there is a lack of a corresponding processing mechanism to avoid the OBU from establishing a connection with the RSU again after the link release. SUMMARY

[0104] To make the technical problems, technical solutions and advantages to be solved in the present application more clear, the following will be described in detail in combination with the accompanying drawings and specific embodiments. In the following description, specific details such as specific configurations and components are provided only to help a comprehensive understanding of the embodiments of the present application. Therefore, it should be clear for those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, in order to be clear and concise, the description of known functions and structures is omitted.

[0105] It should be understood that every feature, structure, or characteristic described herein is within a preferred embodiment of the present application. It should be understood that "one embodiment" or "an embodiment" as described throughout this specification means that a particular feature, structure, or characteristic described is included in at least one embodiment of the application. Therefore, appearances of "in one embodiment" or "in an embodiment" throughout this specification are not necessarily referring to the same embodiment. Furthermore, the particular features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0106] In various embodiments of the present application, it should be understood that the size of the serial number of the following processes does not mean the order of execution, and the execution order of the processes should be determined by its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0107] It should be understood that the term "and / or" herein is only a description of the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can represent: A exists alone, A and B exist together, and B exists alone. In addition, the character " / " herein generally represents that the front and rear associated objects are in an "or" relationship.

[0108] In the embodiments provided in the present application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined according to A. However, it should also be understood that the determination of B according to A does not mean that B is determined only according to A, but B can also be determined according to A and / or other information.

[0109] Referring to Figure 1 A preferred embodiment of the present application provides a processing method of unicast interactive service, applied to a first road side unit, comprising:

[0110] Step S101, after sending a first link release message to the first vehicle-mounted unit, monitoring the received unicast service response information about the first preset service type within the first preset condition, the first link release message is used to release the unicast interactive service of the first preset service type between the first road side unit and the first vehicle-mounted unit;

[0111] Step S102, when the unicast service response information is received within the first preset condition, it is judged whether the unicast service response information is sent by the first vehicle-mounted unit;

[0112] Step S103, when it is determined that the unicast service response information is sent by the first vehicle-mounted unit, a preset processing strategy is executed.

[0113] In a preferred embodiment of the present application, a processing method for unicast interactive services applied to a first road side unit is provided. After the first road side unit sends a first link release message to a first vehicle-mounted unit that has completed unicast interactive services, the first vehicle-mounted unit may continue to respond to the same type of unicast service announcement message due to the first road side unit periodically broadcasting all types of unicast service announcement messages. To avoid repeated interaction between the first road side unit and the first vehicle-mounted unit, the first road side unit monitors the received unicast service response information about the first preset service type within the first preset condition. The specific implementation includes but is not limited to receiving the first unicast service response information sent by the vehicle-mounted unit within the first preset condition, and determining the service type of the first unicast service response message according to the application program identifier (AID) in the first unicast service response information. When the service type of the first unicast service response information is the first preset service type, it is determined that the unicast service response information is monitored. At this time, it is judged whether the unicast service response information is sent by the first vehicle-mounted unit. When it is determined that the unicast service response information is sent by the first vehicle-mounted unit, the original service processing flow is no longer executed, but is processed according to the preselected preset processing strategy, thereby avoiding repeated interaction between the first road side unit and the first vehicle-mounted unit, and further avoiding data interaction abnormalities, repeated billing and other problems, improving the security and efficiency of communication. The limitation of the first preset condition avoids the first vehicle-mounted unit and the first road side unit from interacting again after one interaction, thereby affecting the original function, and avoiding affecting the interests of the owner of the first road side unit.

[0114] Specifically, the processing method for unicast interactive services as described above further includes:

[0115] In the case of being in a link connection state with the first vehicle-mounted unit about the first preset service type and not sending the first link release message, the unicast service response information and / or the first unicast service data information about the first preset service type repeatedly sent by the first vehicle-mounted unit is ignored.

[0116] In a specific embodiment of the present application, in addition to the above-mentioned judgment after the first link release message is sent to the first vehicle-mounted unit, the first roadside unit can also ignore the received unicast service response information and / or first unicast service data information about the first preset service type repeatedly sent by the first vehicle-mounted unit in the case that the first roadside unit is in a link connection state with the first vehicle-mounted unit about the first preset service type and the first link release message has not been sent. The first unicast service data information can be any information sent by the first vehicle-mounted unit between the establishment of link connection and the release of link. Through the above-mentioned ignoring operation, repeated interaction caused by repeated reception of information sent by the first vehicle-mounted unit due to communication abnormalities and other factors can be effectively avoided. Preferably, the processing method of the unicast interactive service as described above, the step of executing the preset processing strategy comprises:

[0117] sending a second link release message to the first vehicle-mounted unit;

[0118] or sending a toll pass obtaining message to the first vehicle-mounted unit;

[0119] or sending a user prompt message to the first vehicle-mounted unit;

[0120] or ignoring the unicast service response information.

[0121] In another preferred embodiment of the present application, the step of executing the preset processing strategy is further exemplified, taking the first preset service type as a near field payment service for example, the step of executing the preset processing strategy comprises:

[0122] the first roadside unit skips the charging information obtaining stage, the toll pass obtaining stage and the user prompting stage, and directly enters the link release stage, i.e. sends a second link release message to the first vehicle-mounted unit again, and directly ends the service processing flow;

[0123] or the first roadside unit skips the charging information obtaining stage and the toll pass obtaining stage, and directly enters the user prompting stage, i.e. sends a user prompt message to the first vehicle-mounted unit, prompts the user that the charging has been successful, avoids repeated charging, and then enters the link release stage to end the service processing flow;

[0124] or the first roadside unit skips the charging information obtaining stage, and directly enters the toll pass obtaining stage, i.e. sends a toll pass obtaining message to the first vehicle-mounted unit, obtains the toll pass of the first vehicle-mounted unit, and further enters the user prompting stage and the link release stage, and finally ends the service processing flow;

[0125] In the above-mentioned three preset processing strategies, the first roadside unit skips the charging information obtaining stage, avoids interaction with the charging system, and further avoids the problem of repeated charging.

[0126] The step of executing the preset processing strategy can also be: when it is determined that the unicast service response information is sent by the first vehicle-mounted unit, directly ignoring the unicast service response information, at this time the first road side unit will not enter the charging information acquisition stage, the toll voucher acquisition stage, the user prompt stage and the link release stage, which can avoid problems such as data interaction and repeated charging, reduce the processing flow, and thus be conducive to reducing resource occupation and improving the processing efficiency of the first road side unit.

[0127] Optionally, when the first preset service type is not the near field payment service, the preset processing strategy can be adjusted according to the corresponding processing stage.

[0128] Referring to Figure 2 , specifically, the method for processing unicast interactive services as described above, the step S102 of determining whether the unicast service response information is sent by the first vehicle-mounted unit comprises:

[0129] Step S201, when the unicast service response information is received within the first preset condition, acquiring interaction information when the first road side unit completes the unicast interactive service of the first preset service type;

[0130] Step S202, when the information in the unicast service response information is consistent with the corresponding information about the first vehicle-mounted unit in the interaction information, determining that the unicast service response information is sent by the first vehicle-mounted unit;

[0131] The unicast service response information and the interaction information both include at least one of the following: system information, vehicle information, IC card pre-reading information, payment account information, vehicle-mounted unit number, passage information and medium access control source address.

[0132] In another preferred embodiment of the present application, the step of determining whether the unicast service response information is sent by the first vehicle-mounted unit is exemplified. When the unicast service response information is received within the first preset condition, the interaction information of the first roadside unit when completing the unicast interaction service of the first preset service type is obtained, wherein the interaction information includes the information currently stored by the first roadside unit or a server connected to the first roadside unit when interacting with the first roadside unit for the first preset service type, and preferably, the interaction information is information within a preset time period. After obtaining the above interaction information, the unicast service response information is searched and compared in the interaction information, and when it is determined that the corresponding information consistent with the information in the unicast service response information exists in the interaction information, and the corresponding information is information about the first vehicle-mounted unit, it is determined that the unicast service response information is sent by the first vehicle-mounted unit. Optionally, when obtaining the interaction information, only the corresponding information when interacting with the first vehicle-mounted unit can be obtained, or when determining, the corresponding information about the first vehicle-mounted unit is selected first, and then the corresponding information about the first vehicle-mounted unit is compared with the information in the unicast service response information to determine whether they are consistent. When the corresponding information about the first vehicle-mounted unit does not exist in the interaction information, the original processing flow is executed. In a specific embodiment, taking the first preset service type as the near field payment service as an example, the unicast service response information and the interaction information each include at least one of the following: system information, vehicle information, IC card pre-reading information, payment account information, vehicle-mounted unit number, passing information, and medium access control source address. When determining, each item of information in the unicast service response information is compared with the corresponding information in the interaction information, and when there is a consistent condition, and the corresponding information when consistent is information about the first vehicle-mounted unit, it is thus determined that the unicast service response information is sent by the first vehicle-mounted unit, and a preset processing strategy is executed, thereby avoiding problems such as repeated interaction between the first roadside unit and the first vehicle-mounted unit.

[0133] Further, the processing method of the unicast interaction service as described above, the first preset condition includes at least one of the first preset time length and the first preset distance;

[0134] The first preset time length and the first preset distance are related to at least one of the vehicle speed of the first vehicle-mounted unit, the front road condition of the first vehicle-mounted unit, and the communication range of the roadside unit when the first link release message is sent.

[0135] In another specific embodiment of the present application, the first preset condition comprises at least one of the first preset time length and the first preset distance, that is, after the first roadside unit sends the first link release message to the first vehicle-mounted unit, timing is performed, the step of monitoring the unicast service response information about the first preset service type received within the first preset condition is performed within the first preset time length, and / or, after the first roadside unit sends the first link release message to the first vehicle-mounted unit, the motion distance of the first vehicle-mounted unit or the relative distance between the first vehicle-mounted unit and the first roadside unit is obtained, and in the case that the motion distance or the relative distance is less than the first preset distance, the step of monitoring the unicast service response information about the first preset service type received within the first preset condition is performed.

[0136] Specifically, the first preset time length and the first preset distance are determined according to at least one of the vehicle speed of the first vehicle-mounted unit when the first link release message is sent, the road condition in front of the first vehicle-mounted unit, and the communication range of the roadside unit, that is, a corresponding relationship between the first preset time length and at least one of the vehicle speed, the road condition, and the communication range can be established in advance, which includes but is not limited to a functional relationship and a mapping relationship, and then the corresponding first preset time length can be obtained when the vehicle speed, the road condition, and / or the communication range are obtained. Similarly, a corresponding relationship between the first preset distance and at least one of the vehicle speed, the road condition, and the communication range can be established in advance, and preferably the first preset distance can be equal to the communication range of the first roadside unit.

[0137] Referring to Figure 3 In another preferred embodiment of the present application, a processing method of unicast interactive service is applied to a second vehicle-mounted unit, comprising:

[0138] Step S301, after receiving a third link release message sent by a second roadside unit, monitoring received unicast service announcement information about a second preset service type under a second preset condition, the third link release message is used to release the unicast interactive service of the second preset service type between the second roadside unit and the second vehicle-mounted unit;

[0139] Step S302, when the unicast service announcement information is received within the second preset condition, determining whether the unicast service announcement information is sent by the second roadside unit;

[0140] Step S303, when it is determined that the unicast service announcement information is sent by the second roadside unit, ignoring the unicast service announcement information;

[0141] Step S304, when the third preset condition is met, performing link release according to the third link release message.

[0142] In another preferred embodiment of the present application, a processing method for unicast interactive service applied to a second vehicle-mounted unit is also provided. After receiving a third link release message about a second preset service type sent by a second roadside unit, the second vehicle-mounted unit monitors received unicast service announcement information about the second preset service type under a second preset condition. That is, under the second preset condition, after receiving a unicast service announcement information, first, the service type of the unicast service announcement information is determined according to the application identifier in the unicast service announcement information. When the service type is the second preset service type, the step of determining whether the unicast service announcement information is sent by the second roadside unit is performed, that is, whether it is a repeated service initiated by the second roadside unit is determined. When it is determined that the unicast service announcement information is sent by the second roadside unit, it indicates that the second vehicle-mounted unit receives the repeated service initiated by the same roadside unit under the second preset condition. At this time, the unicast service announcement information is ignored, that is, no response is made to the unicast service announcement information, which can avoid problems such as repeated interaction, abnormal data interaction, repeated charging, and the like. Further, since link release needs to be performed after receiving the third link release message to completely disconnect the link connection with the second roadside unit, under a third preset condition of link release, link release is performed according to the third link release message, which reduces the consumption of resources and / or energy and the like by link connection.

[0143] Specifically, the processing method for unicast interactive service as described above further includes:

[0144] In the case of being in a link connection state with the second roadside unit about the second preset service type and not receiving the third link release message, the unicast service announcement information and / or the second unicast service data information about the second preset service type repeatedly sent by the second roadside unit is ignored.

[0145] In a specific embodiment of the present application, in addition to the above-mentioned processing after receiving the third link release message sent by the second roadside unit, the received unicast service announcement information and / or the second unicast service data information about the second preset service type repeatedly sent by the second roadside unit can also be ignored under the condition that the second roadside unit is in a link connection state with the second vehicle-mounted unit about the second preset service type and does not receive the second link release message. The second unicast service data information can be any information sent by the second roadside vehicle-mounted unit between the establishment of link connection and the link release. Through the above-mentioned ignoring operation, repeated interaction caused by repeated reception of information sent by the second roadside unit due to communication abnormalities and the like can be effectively avoided.

[0146] Referring to Figure 4In particular, the processing method of the unicast interactive service as described above, when it is determined that the unicast service announcement information is sent by the second road side unit, the step S303 of ignoring the unicast service announcement information further comprises:

[0147] In step S401, the motion state of the vehicle-mounted unit is acquired.

[0148] In step S402, when it is determined that the unicast service announcement information is sent by the second road side unit and the motion state is a preset state, the unicast service announcement information is ignored.

[0149] In a preferred embodiment of the present application, in order to ensure the accuracy of the above steps and avoid misjudgment caused by the vehicle-mounted unit itself, the motion state of the vehicle-mounted unit is further acquired when the step is executed. When it is determined that the unicast service announcement information is sent by the second road side unit and the motion state is a preset state, the unicast service announcement information is ignored. The preset state includes but is not limited to that the vehicle-mounted unit does not produce displacement and / or the vehicle-mounted unit does not produce U-turn. For example, when the parking lot or the road entrance and exit are controlled by the same road side unit, the above-mentioned motion state judgment can avoid the situation that the vehicle cannot drive out because it cannot complete the interaction when it drives in and then immediately drives out.

[0150] Preferably, the processing method of the unicast interactive service as described above, when the unicast service announcement information is received in the second preset condition, the step of determining whether the unicast service announcement information is sent by the second road side unit comprises:

[0151] When the unicast service announcement information is received in the second preset condition, the identification information of the road side unit with which the second vehicle-mounted unit completes the unicast interactive service of the second preset service type is acquired. The identification information and the unicast service announcement information both include at least one of the following information: medium access control source address, charging type, location coordinate information of the road side unit, charging information and road side unit number;

[0152] When the message layer of the second vehicle-mounted unit determines that the information in the unicast service announcement information is consistent with the corresponding information in the identification information, it is determined that the unicast service announcement information is sent by the second road side unit;

[0153] And / or, when the network layer of the second vehicle-mounted unit determines that the medium access control source address in the unicast service announcement information is consistent with the medium access control source address in the identification information, it is determined that the unicast service announcement information is sent by the second road side unit.

[0154] Preferably, when judging whether the unicast service announcement information is sent by the second road side unit, the identification information of the second road side unit with which the second vehicle-mounted unit completes the second preset type of unicast interactive service is acquired first, and the identification information can be used to identify the second road side unit, wherein the identification information and the unicast service announcement information both include at least one of the following information: a medium access control source address, a charging type, position coordinate information of the road side unit, charging information and a road side unit number;

[0155] When the identification information is acquired, the message layer of the second vehicle-mounted unit judges according to the identification information and the unicast service announcement information, and when the information in the unicast service announcement information is consistent with the corresponding information in the identification information, it is determined that the unicast service announcement information is sent by the second road side unit.

[0156] And / or, when the medium access control source address is included in both the identification information and the unicast service announcement information, when the network layer of the second vehicle-mounted unit determines that the medium access control source address in the unicast service announcement information is consistent with the medium access control source address in the identification information, it is determined that the unicast service announcement information is sent by the second road side unit.

[0157] Specifically, the processing method of the unicast interactive service as described above, the second preset condition includes at least one of the following:

[0158] The second vehicle-mounted unit is within a second preset time length and / or a second preset distance after receiving the third link release message;

[0159] The second vehicle-mounted unit is within the communication range of the second road side unit;

[0160] The second vehicle-mounted unit does not perform unicast interactive service with other road side units about the second preset type of service.

[0161] In a specific embodiment of the present application, the second preset condition as described above can be that the second vehicle-mounted unit is within a second preset time length and / or a second preset distance after receiving the third link release message, and through the second preset time length and / or the second preset distance, the second vehicle-mounted unit can be effectively prevented from interacting with the same road side unit multiple times in a short time.

[0162] The second preset condition as described above can also be that the second vehicle-mounted unit is within the communication range of the second road side unit, which can effectively reduce the resource and / or energy consumption caused by the step of still performing the above-mentioned judgment when the unicast service announcement information obviously cannot be sent by the same road side unit.

[0163] The second preset condition can also be that the second vehicle-mounted unit does not perform unicast interaction with other roadside units about the second preset service type. After the second vehicle-mounted unit performs unicast interaction with other roadside units about the second service type, it is considered that the service associated with the second roadside unit has been covered or has been completed in full, for example, in a regional toll road section, if no interaction with an exit roadside unit occurs, no interaction with an entrance roadside unit will occur again, which can effectively avoid problems such as repeated charging or charging confusion.

[0164] Preferably, the processing method of the unicast interaction service as described above, the second preset time length and the second preset distance are related to at least one of the position coordinates, the road conditions ahead, the vehicle speed, and the communication range of the roadside unit when the second vehicle-mounted unit receives the third link release message.

[0165] Alternatively, the second preset time length is related to the time length information carried in the third link release message, and the second preset distance is related to the distance information carried in the third link release message.

[0166] In a specific embodiment of the present application, the second preset time length and the second preset distance defined above can be determined according to at least one of the position coordinates, the road conditions ahead, the vehicle speed, and the communication range of the roadside unit when the second vehicle-mounted unit receives the third link release message. The specific manner includes but is not limited to pre-establishing a corresponding relationship between the second preset time length and / or the second preset distance and at least one of the vehicle speed, the road conditions, and the communication range, which includes but is not limited to a functional relationship and a mapping relationship, so that when the vehicle speed, the road conditions, and / or the communication range are obtained, the corresponding second preset time length and / or the second preset distance can be obtained.

[0167] Alternatively, the second preset time length can be related to the time length information in the third link release message sent by the second roadside unit, that is, it can be indicated by the second roadside unit, reducing the consumption of computing resources. Similarly, the second preset distance can also be indicated by the second roadside unit through the distance information in the third link release message.

[0168] Specifically, the processing method of the unicast interaction service as described above, the third preset condition includes at least one of the third preset time length and the third preset distance.

[0169] The third preset time length and the third preset distance are related to at least one of the position coordinates, the road conditions ahead, the vehicle speed, and the communication range of the roadside unit when the second vehicle-mounted unit receives the third link release message.

[0170] Alternatively, the third preset time length is related to the time length information carried in the third link release message, and the third preset distance is related to the distance information carried in the third link release message.

[0171] In a specific embodiment of the present application, the third preset time length and the third preset distance defined above can be determined according to at least one of the position coordinates of the second vehicle-mounted unit when the third link release message is received, the road conditions ahead, the vehicle speed, and the communication range of the road side unit. The specific manner includes but is not limited to pre-establishing a corresponding relationship between the third preset time length and / or the third preset distance and at least one of the vehicle speed, the road conditions, and the communication range, which includes but is not limited to a functional relationship and a mapping relationship. Thus, when the vehicle speed, the road conditions, and / or the communication range are obtained, the corresponding third preset time length and / or third preset distance can be obtained.

[0172] Alternatively, the third preset time length can be related to the time length information in the third link release message sent by the second road side unit, i.e., it can be indicated by the second road side unit. Similarly, the third preset distance can also be indicated by the second road side unit through the distance information in the third link release message.

[0173] Preferably, the third preset time length is greater than or equal to the second preset time length, and the third preset distance is greater than or equal to the second preset distance.

All the implementation means in the above-mentioned method embodiment are applicable to the second vehicle-mounted unit embodiment, and can also achieve the same technical effects.

[0217] A further preferred embodiment of the present application also provides a unicast service processing system of vehicle networking, comprising at least one vehicle-mounted unit and at least one road-side unit connected through vehicle networking communication;

[0218] The vehicle-mounted unit is the second vehicle-mounted unit as described above.

[0221] A further preferred embodiment of the present application also provides a computer program readable storage medium, on which a computer program is stored, and the computer program is executed by a processor to implement the steps of the processing method of the unicast interactive service applied to the first road-side unit as described above, or implement the steps of the processing method of the unicast interactive service applied to the second vehicle-mounted unit as described above.

[0222] Referring to Figure 7 Optionally, in another preferred embodiment of the present application, a processing method of unicast interactive service is also disclosed, applied to a third road-side unit, comprising:

[0223] Step S701, when receiving the unicast service response information about the third preset service type sent by the third vehicle-mounted unit, obtaining the first historical service processing information about the third preset service type stored by the third road-side unit;

[0224] Step S702, judging whether the unicast service response information is the repeated service response information according to the first historical service processing information;

[0225] Step S703, when determining that the unicast service response information is the repeated service response information, executing a preset processing strategy.

[0226] In a preferred embodiment of the present application, a processing method for unicast interactive services applied to a third road side unit is provided. After receiving a second unicast service response information sent by a third vehicle-mounted unit, the third road side unit determines a third preset service type of the second unicast service response information according to an application identifier in the second unicast service response information, acquires first historical service processing information about the third preset service type stored in the third road side unit, and determines whether the unicast service response information is repeated service response information according to the first historical service processing information. If it is determined that the unicast service response information is repeated service response information, the original service processing procedure is not executed, but a preset processing strategy is executed to avoid repeated interaction between the third road side unit and the third vehicle-mounted unit, and further avoid data interaction abnormalities, repeated billing and other problems, thereby improving the safety and efficiency of communication.

[0227] Preferably, since the vehicle-mounted unit only stores the first historical service processing information in a preset time period, if the first historical service processing information about the third preset service type stored in the third road side unit is not acquired, the original service processing procedure is executed.

[0228] Preferably, in the processing method for unicast interactive services, the step of executing the preset processing strategy includes:

[0229] Ignoring the unicast service response information.

[0230] The step of executing the preset processing strategy can also be that when it is determined that the unicast service response information is repeatedly sent by the third vehicle-mounted unit, the unicast service response information is directly ignored. At this time, the third road side unit does not enter the charging information acquisition stage, the pass voucher acquisition stage, the user prompt stage and the link release stage again, thereby avoiding data interaction, repeated billing and other problems, reducing the processing procedure, and further reducing resource occupation and improving the processing efficiency of the third road side unit.

[0231] Optionally, when the third preset service type is not a near field payment service, the preset processing strategy can be adjusted according to the corresponding processing stage.

[0232] Referring to Figure 8 , specifically, in the processing method for unicast interactive services, the step of determining whether the unicast service response information is repeated service response information according to the first historical service processing information includes:

[0233] Step S801, when there is corresponding information consistent with the information in the unicast service response information in the target historical service processing information, obtaining a first time difference and / or a first distance difference between the third road side unit when obtaining the target historical processing information and when receiving the unicast service response information;

[0234] Step S802, when the first time difference is not greater than a fourth preset time length and / or the first distance difference is less than or equal to a fourth preset distance, determining that the unicast service response information is the repeated service response information.

[0235] In a specific embodiment of the present application, when it is determined that there is corresponding information consistent with the information in the unicast service response information in the target historical service processing information, the target historical service processing information is determined to be historical information corresponding to the unicast service response information. Preferably, when there are multiple historical information corresponding to the unicast service response information, the historical information closest to the current time is determined to be the target historical service processing information. At this time, the time difference between the third road side unit when obtaining the target historical service processing information and receiving the unicast service response information and / or the distance difference of the third vehicle-mounted unit are obtained, wherein the first time difference is the difference between the historical time corresponding to the target historical service processing information and the current time when receiving the unicast service response information, and the first distance difference is the difference between the historical position of the third vehicle-mounted unit corresponding to the target historical service processing information and the current position of the third vehicle-mounted unit when receiving the unicast service response information or the difference between the position of the third road side unit and the current position of the third vehicle-mounted unit.

[0236] When the first time difference is not greater than a third preset time length and / or the first distance difference is less than or equal to a fourth preset distance, it can be determined that the third vehicle-mounted unit has responded to the fourth preset type of service about the third road side unit again in a short time, and therefore the unicast service response information is determined to be the repeated service response information.

[0237] Further, as described above, the processing method of the unicast interactive service, the fourth preset time length and / or the fourth preset distance are related to at least one of the speed of the third vehicle-mounted unit when obtaining the target historical service processing information, the road condition in front of the third vehicle-mounted unit, and the communication range of the road side unit.

[0238] In another specific embodiment of the present application, specifically, the fourth preset time length and the fourth preset distance are determined according to at least one of a vehicle speed of the third vehicle-mounted unit, a road condition in front of the third vehicle-mounted unit, and a communication range of the third road side unit when the target historical service processing information is acquired, that is, a corresponding relationship between the fourth preset time length and at least one of the vehicle speed, the road condition, and the communication range can be established in advance, and the corresponding relationship includes but is not limited to a functional relationship and a mapping relationship, so that the corresponding fourth preset time length can be obtained when the vehicle speed, the road condition, and / or the communication range are acquired. Similarly, a corresponding relationship between the fourth preset distance and at least one of the vehicle speed, the road condition, and the communication range can be established in advance, and preferably, the fourth preset distance can be equal to the communication range of the third road side unit.

[0239] Specifically, the processing method of the unicast interactive service, and has the characteristics that the target historical service processing information and the unicast service response information both include at least one of the following: system information, vehicle information, IC card pre-reading information, payment account information, vehicle-mounted unit number, passing information, and medium access control source address.

[0240] Referring to Figure 9 Optionally, in another preferred embodiment of the present application, a processing method of a unicast interactive service is also disclosed, applied to a fourth vehicle-mounted unit, and includes the following steps:

[0241] Step S901, when receiving the unicast service announcement information about the fourth preset service type sent by the fourth road side unit, acquiring historical service interaction information about the fourth preset service type stored by the fourth road side unit;

[0242] Step S902, determining whether the unicast service announcement information is repeated service announcement information according to the historical service interaction information;

[0243] Step S903, when determining that the unicast service announcement information is repeated service announcement information, ignoring the unicast service announcement information.

[0244] In a specific embodiment of the present application, when the fourth on-board unit receives the first unicast service announcement information sent by the fourth roadside unit, the fourth preset service type of the first unicast service announcement message is determined according to the application program identifier in the first unicast service announcement information, and the historical service interaction information about the fourth preset service type is obtained from the stored information, and whether the received unicast service announcement information is repeated service announcement information is determined according to the historical service interaction information. If the unicast service announcement information is not repeated service announcement information, the original processing flow is processed, and if the unicast service announcement information is repeated service announcement information, in order to avoid repeated interaction between the fourth roadside unit and the fourth on-board unit due to still executing the original service processing flow, and further leading to data interaction abnormalities, repeated billing and other problems, the safety and efficiency of communication are improved.

[0245] Optionally, due to the limitation of the storage space of the on-board unit, the stored information can be overwritten or deleted after a preset time period.

[0246] Referring to Figure 10 , preferably, the processing method of the unicast interactive service as described above, the step S902 of determining whether the unicast service announcement information is repeated service announcement information according to the historical service interaction information comprises:

[0247] Step 1001, obtaining the identification information of the roadside unit with which the fourth on-board unit completes the unicast interactive service of the fourth preset service type;

[0248] Step 1002, determining whether there is target historical service interaction information corresponding to the fourth roadside unit in the historical service interaction information according to the identification information and the unicast service announcement information;

[0249] Step 1003, when it is determined that there is the target historical service interaction information, obtaining the second time difference and / or the second distance difference of the fourth on-board unit when obtaining the target historical service interaction information and when receiving the unicast service announcement information;

[0250] Step 1004, when the second time difference is less than or equal to a preset fifth preset time length, and / or the second distance difference is less than or equal to a preset fifth preset distance, it is determined that the unicast service response information is the repeated service response information.

[0251] In a specific embodiment of the present application, when judging whether the unicast service announcement information is repeated service announcement information according to the historical service interaction information, the identification information of the roadside unit with which the fourth vehicle-mounted unit completes the unicast interaction service of the fourth preset service type is first acquired, and then whether there is target historical service interaction information corresponding to the fourth roadside unit in the historical service interaction information can be judged according to the identification information and the unicast service announcement information. If there is not, it can be determined that the unicast service announcement information is not repeated service announcement information. If there is, the second time difference or the second distance difference when the target historical service interaction information is acquired and the current time are judged. Specifically, the second distance difference is the actual moving path length of the vehicle-mounted unit, the distance between the current position of the vehicle-mounted unit and the position of the vehicle-mounted unit when the target historical service interaction information is acquired, the distance between the current vehicle-mounted unit and the fourth roadside unit, or the difference between the distance between the current vehicle-mounted unit and the fourth roadside unit and the distance between the vehicle-mounted unit and the fourth roadside unit when the target historical service interaction information is acquired.

[0252] When the second time difference is less than or equal to a preset fifth preset time length, and / or the second distance difference is less than or equal to a preset fifth preset distance, it is considered that the current fourth vehicle-mounted unit has not left the communication range of the fourth roadside unit after interacting with the fourth roadside unit. At this time, it is determined that the unicast service response information is the repeated service response information, and the unicast service announcement information can be ignored to avoid repeated interaction of the fourth vehicle-mounted unit with the fourth roadside unit.
