Based on the above system architecture, as shown in fig. 4, an embodiment of the present application provides a method for managing a roadside unit, where the method may include S101-S1010:

s101, the message access gateway of V2X receives the target registration request sent by the first RSU.

In order to realize the unified management of the management subsystem on a large number of first RSUs, the first RSUs produced by different manufacturers can be registered in a unified mode, the registered first RSUs can be communicated with an intelligent networked automobile to complete information interaction with the intelligent networked automobile, meanwhile, the registered first RSUs can be accessed into a mobile communication network to perform information interaction with an MEC platform or a cloud platform, and the information interaction between the management subsystem and the first RSUs needs to be completed through a V2X message access gateway, so that the V2X message access gateway can receive a target registration request sent by the first RSUs.

The target registration request carries the IMEI of the first RSU.

Since the IMEI of the communication modules of different first RSUs are different, the management subsystem may identify the first RSU according to the IMEI, so that the target registration request sent by the first RSU to the V2X message access gateway may carry the IMEI of the first RSU, and it should be noted that the IMEI is the IMEI of the communication module of the first RSU.

Specifically, step S101 is one of specific implementations of S201 in fig. 20.

S102, V2X message access gateway sends target registration request to management subsystem.

Specifically, step S102 is one of the specific implementations of S202 in fig. 20.

S103, the management subsystem receives the target registration request sent by the V2X message access gateway.

S104, when the management subsystem determines that the IMEI is legal, a sequence number corresponding to the IMEI is created, and a target mapping relation used for indicating the corresponding relation between the IMEI and the sequence number is generated.

In order to ensure that the first RSUs registered in the management subsystem are all legal devices, and thus ensure the security of the system after the first RSUs access the car networking system, after receiving a target registration request sent by a V2X message access gateway, the management subsystem first needs to determine the validity of the IMEI of the first RSUs; further, in order to ensure that the first RSUs logged in the management subsystem are all devices registered in the management subsystem, when the IMEI is determined to be legal, a sequence number corresponding to the IMEI may be created, and a target mapping relationship indicating a corresponding relationship between the IMEI and the sequence number may be generated.

Specifically, step S104 is one of the specific implementations of S203 in fig. 20.

Optionally, as shown in fig. 5, when the management subsystem determines that the IMEI is legal, the management subsystem in step S104 creates a sequence number corresponding to the IMEI, and generates a target mapping relationship for indicating a corresponding relationship between the IMEI and the sequence number, which may specifically include: S10411-S10418:

s10411, the management subsystem creates a sequence number corresponding to the IMEI and generates a target mapping relation for indicating the corresponding relation between the IMEI and the sequence number.

S10412, the management subsystem sends a first request carrying the sequence number and the target mapping relation to the V2X message access gateway.

Since the first RSU communicates with the car networking system using a Subscriber Identity Module (SIM) card, each SIM card having a different IMSI, to further ensure the security of the first RSU registered with the management subsystem, the management subsystem may send a first request to the first RSU via the V2X message access gateway, the first request requesting the first RSU for the IMSI of the SIM card used by the first RSU.

Specifically, step S10412 is one of specific implementations of S206 in fig. 20.

Optionally, before the step S10412, that is, before the management subsystem sends the first request carrying the sequence number and the target mapping relationship to the V2X message access gateway, the management subsystem may send a first target registration response (corresponding to S204 and S205 in fig. 20) carrying the sequence number and the target mapping relationship indicating the correspondence between the IMEI and the sequence number to the first RSU through the V2X message access gateway, and after sending the first target registration response to the first RSU, perform the step S10412.

And S10413, the V2X message access gateway receives the first request carrying the sequence number and the target mapping relation sent by the management subsystem.

It should be noted that the V2X message access gateway has a temporary storage function, and when receiving a message carrying a sequence number and a target mapping relationship sent by the management subsystem, may store the received sequence number and the target mapping relationship.

S10414, V2X the message access gateway sends the first request to the first RSU.

Specifically, step S10414 is one of specific implementations of S207 in fig. 20.

S10415, V2X the message access gateway receives the first response sent by the first RSU.

The first response carries the sequence number, the target mapping relation and the IMSI of the first RSU. Specifically, step S10415 is one of specific implementations of S208 in fig. 20.

S10416, V2X the message access gateway sends a first response to the management subsystem.

Specifically, step S10416 is one of the specific implementation manners of S209 in fig. 20.

And S10417, the management subsystem receives the first response sent by the V2X message access gateway.

S10418, when the management subsystem determines that the sequence number and the target mapping relation are both correct, updating the target mapping relation according to the IMSI, so that the updated target mapping relation is used for indicating the corresponding relation among the sequence number, the IMEI and the IMSI.

After the V2X message access gateway sends the first request to the first RSU, the sequence number in the first response sent by the first RSU received by the V2X message access gateway may be abnormal, so when the management subsystem receives the first response sent by the V2X message access gateway, the sequence number carried in the first response is compared to ensure that the first RSU with a correct sequence number is registered; further, since there may be a situation that a plurality of first RSUs are simultaneously registered in the management subsystem, in order to avoid that the registration result is affected by a situation that a target mapping relationship is confused when the plurality of first RSUs are simultaneously registered in the management subsystem, when the management subsystem receives the first response sent by the V2X message access gateway, the target mapping relationship carried by the first response also needs to be compared, and when the sequence number and the target mapping relationship are determined to be correct, the target mapping relationship is updated to the corresponding relationship used for indicating the sequence number, the IMEI, and the IMSI.

Alternatively, as shown in fig. 5, the steps S10416 to S10418 may be replaced by the steps S10419 to S10422:

s10419, V2X the message access gateway determines whether the sequence number carried by the first response is correct.

Since the V2X message access gateway stores the first request carrying the sequence number of the first RSU and the target mapping relationship received from the management subsystem, in order to improve the registration efficiency of the first RSU, before the V2X message access gateway sends the second response to the management subsystem, the sequence number of the first RSU is compared first, and when the sequence number is determined to be correct, the second response is sent to the management subsystem.

It should be noted that since the storage space of the V2X message access gateway is small, there is a possibility that the stored target mapping relationship may be misaligned, and therefore, only the sequence number is confirmed here, and the target mapping relationship is confirmed by the management subsystem.

And S10420, when the serial number is determined to be correct, sending a second response to the management subsystem.

And the second response carries the target mapping relation and the IMSI of the first RSU.

And S10421, the management subsystem receives the second response sent by the V2X message access gateway.

S10422, when the management subsystem determines that the target mapping relation is correct, updating the target mapping relation according to the IMSI, so that the updated target mapping relation is used for indicating the corresponding relation among the serial number, the IMEI and the IMSI.

Since the first RSU sends the target registration request to the management subsystem through the V2X message access gateway, the target registration request may simultaneously carry the IMEI of the first RSU and the IMSI of the first RSU, so when the management subsystem determines that the IMEI is legal, the target mapping relationship among the IMEI, the IMSI and the sequence number may be directly created, so, optionally, as shown in fig. 6, creating the sequence number corresponding to the IMEI in step S104, and generating the target mapping relationship for indicating the corresponding relationship between the IMEI and the sequence number may specifically include S1042:

s1042, creating a sequence number corresponding to the IMEI, and generating a target mapping relation for indicating the corresponding relation among the IMEI, the IMSI and the sequence number.

Optionally, as shown in fig. 7, when the management subsystem determines that the IMEI is legal, the management subsystem in step S104 creates a sequence number corresponding to the IMEI, and generates a target mapping relationship for indicating a corresponding relationship between the IMEI and the sequence number, which may further include: S1043-S1044:

s1043, creating a sequence number corresponding to the IMEI, and generating a target mapping relation for indicating the corresponding relation between the IMEI and the sequence number.

S1044 creates an access password and/or key for the first RSU and inserts the access password and/or key into the target registration reply sent to the V2X message access gateway.

The access password may be a string of plaintext, the key may be a string of encrypted data randomly generated by the management subsystem, when the first RSU logs in the management subsystem, the management subsystem or the V2X message access gateway may authenticate the access password and/or the key carried in the login request of the first RSU, and after the authentication is passed, send a login request reply to the first RSU, so as to further ensure the security of the system after the first RSU registered by the management subsystem accesses the car networking system.

S105, the management subsystem sends a target registration response to the V2X message access gateway.

The target registration response carries the sequence number, the target mapping relation and the registration identifier, and the registration identifier is used for indicating that the first RSU is registered completely.

Optionally, after the step S105, that is, after the first RSU receives the target mapping relationship carrying the corresponding relationship between the indication IMEI and the sequence number, the third request carrying the sequence number, the target mapping relationship, and the IMSI (which may be called as a first login request in practice) may also be directly sent to the V2X message access gateway (corresponding to S2011 in fig. 20), when the V2X message access gateway receives the third request sent by the first RSU and determines that the sequence number carried by the third request is correct (corresponding to S2012 in fig. 20), the third request is forwarded to the management subsystem (corresponding to S2013 in fig. 20), and after the management subsystem determines that the target mapping relationship carried by the third request is correct, the target mapping relationship is updated according to the IMSI carried by the third request, so that the updated target mapping relationship is used to indicate the corresponding relationship between the IMEI, the changed IMSI, and the sequence number (corresponding to S2014 in fig. 20), after the update, the V2X message access gateway retransmits a target registration response (actually, the target registration response may be a first login response corresponding to the first login request) to the first RSU, where the target registration response carries the sequence number, the updated target mapping relationship, and the registration identifier (corresponding to S2015 and S2016 in fig. 20).

Optionally, the target registration response may further carry a registration state identifier, where the registration state identifier may be an identifier that is created by the management subsystem for the first RSU after receiving the target registration request sent by the V2X message access gateway and used for indicating a registration state of the first RSU, where the registration state identifier includes a flag bit, an initial state of the flag bit is unregistered, and when the management subsystem creates a sequence number and a target mapping relationship for the first RSU, indicating that the first RSU has been successfully registered in the management subsystem, the management subsystem may change the flag bit included in the registration state identifier from initial unregistered to registered, and send the changed registration state identifier including the registered flag bit to the V2X message access gateway. It should be noted that, when the subsequent first RSU needs to log in the management subsystem and sends a login request to the management subsystem, the login request should carry a registration status identifier so that the management subsystem determines whether the first RSU has been registered; of course, if the first RSU is the first RSU that has already been registered, the login request should also carry the registration identifier.

Optionally, after the management subsystem creates a serial number and a target mapping relationship for the first RSU and changes the flag bit of the registration identifier, the management subsystem may generate a registration log of the first RSU, where the registration log may include information such as a registration date of the first RSU.

And S106, the V2X message access gateway receives the target registration response sent by the management subsystem.

S107, V2X message access gateway sends a target registration reply to the first RSU.

And S108, the management subsystem sends a management instruction to the V2X message access gateway.

Wherein, the management instruction is at least one of the following: the system comprises a parameter configuration instruction, a parameter extraction instruction, an information strategy reporting instruction, a remote control instruction and a remote upgrading instruction.

And S109, the V2X message access gateway receives the management instruction sent by the management subsystem.

S1010, V2X the message access gateway sends a management instruction to the second RSU.

It should be noted that the second RSU is any one of the first RSUs, and specifically, the second RSU is the first RSU that is registered in the management subsystem and logged in the management subsystem.

As the second RSU can perform data interaction with other platforms only after being in the LOGIN state, optionally, referring to fig. 8, an embodiment of the present application further provides a signaling interaction diagram that the registered second RSU logs in the management subsystem, first, the second RSU sends a LOGIN request (LOGIN) (corresponding to 11 in fig. 8) to the V2X message access gateway, where the LOGIN request carries a serial number, a target mapping relationship, and a registration identifier of the second RSU; after the V2X message access gateway receives the login request sent by the second RSU, performs access authentication on the serial number carried in the login request (corresponding to 12 in fig. 8), and forwards the login request to the management subsystem (corresponding to 13 in fig. 8) when the serial number is determined to be correct; after receiving a LOGIN request forwarded by a V2X message access gateway, a management subsystem determines whether a flag bit of a registration state identifier carried by the LOGIN request is registered or whether the LOGIN request carries a registration identifier, and when the flag bit is registered or the LOGIN request carries the registration identifier, performs order relation authentication (corresponding to 14 in fig. 8) on a target mapping relation carried by the LOGIN request, and after the authentication is passed, sends a LOGIN request response (LOGIN _ ACK) to a second RSU through the V2X message access gateway (corresponding to 15 and 16 in fig. 8); after receiving the response of the login request, the second RSU sends a configuration report (CONFIG _ TRAP) (corresponding to 17 in fig. 8) to the V2X message access gateway, that is, a message that tells the V2X that the message access gateway itself successfully logs in; the V2X message access gateway replies a configuration report reply (CONFIG _ TRAP _ ACK) to the second RSU after receiving the configuration report (corresponding to 18 in fig. 8), and simultaneously sends a login success notification (corresponding to 19 in fig. 8) to the management subsystem, that is, a message that the second RSU has successfully logged in is notified to the management subsystem, and the management subsystem replies a login success notification reply (corresponding to 20 in fig. 8) to the V2X message access gateway after receiving the login success notification.

It should be further noted that, after the management subsystem receives the login request forwarded by the V2X message access gateway, if it is determined that the flag bit of the registration status identifier carried in the login request is unregistered or the login request carries the registration identifier, the management subsystem needs to send a re-registration request to the second RSU through the V2X message access gateway.

The parameter configuration instruction is at least used for indicating the second RSU logged in the management subsystem to update the self configuration according to the configuration information carried in the parameter configuration instruction.

Illustratively, referring to fig. 9, a signaling interaction diagram of the management subsystem for performing parameter configuration on the second RSU is provided, specifically, the management subsystem first sends a configuration request (CONFIG _ SET) (corresponding to 21 in fig. 9) to the V2X message access gateway; when the V2X message access gateway receives the configuration request sent by the management subsystem, it replies a configuration request acknowledgement (CONFIG _ SET _ RSP) to the management subsystem (corresponding to 22 in fig. 9), and sends a configuration request (CONFIG _ SET) to the second RSU (corresponding to 23 in fig. 9); when the second RSU receives the configuration request sent by the V2X message access gateway, it replies a configuration request result (CONFIG _ SET _ ACK) (corresponding to 24 in fig. 9) to the V2X message access gateway; after receiving the configuration request result replied by the second RSU, the V2X message access gateway sends the configuration request result (corresponding to 25 in fig. 9) to the management subsystem; after receiving the configuration request result sent by the V2X message access gateway, the management subsystem replies a configuration request result acknowledgement (CONFIG _ SET _ ACK _ RSP) (corresponding to 26 and 27 in fig. 9) to the second RSU through the V2X message access gateway, where the configuration request result acknowledgement carries configuration information; after receiving the configuration request result confirmation, the second RSU temporarily stores the configuration information carried by the configuration request result confirmation, and saves the original configuration (corresponding to 28 in fig. 9); the management subsystem confirms whether the written new parameters need to be restarted or not according to the types of the parameters in the configuration information, when the new parameters need not to be restarted, the second RSU writes the new parameters and takes effect (corresponding to 2910 in fig. 9), and sends a configuration report (CONFIG _ TRAP) (corresponding to 2911 and 2912 in fig. 9) to the management subsystem through the V2X message access gateway, wherein the configuration report carries the result of successful or failed configuration of the second RSU parameters; after receiving the configuration report, the management subsystem sends a configuration report reply (CONFIG _ TRAP _ ACK) (corresponding to 2913 and 2914 in fig. 9) to the second RSU through the V2X message access gateway; when the restart is confirmed, the second RSU first needs to log out through the V2X message access gateway (corresponding to 2920 and 2921 in fig. 9), re-initiate a log-in process (corresponding to 2924 in fig. 9) after receiving a log-out reply (corresponding to 2922 and 2923 in fig. 9) sent by the management subsystem through the V2X message access gateway (the specific log-in process may refer to fig. 8), after the log-in is confirmed, write in new parameters and take effect (corresponding to 2925 in fig. 9) by the second RSU, and finally send a configuration report (corresponding to 2926 and 2927 in fig. 9) to the management subsystem through the V2X message access gateway; after receiving the configuration report, the management subsystem sends a configuration report reply (corresponding to 2928 and 2929 in fig. 9) to the second RSU through the V2X message access gateway.

In addition, when the configuration information of the second RSU is lost or damaged, the configuration request may also be initiated to the management subsystem through the V2X message access gateway, as shown in fig. 10, a signaling interaction diagram is provided in which the second RSU initiates the configuration request to the management subsystem, and a specific configuration process is similar to a process in which the management subsystem initiates the configuration request to the second RSU, and is not described here again. In addition, except that the second RSU needs to log out in the above-mentioned parameter configuration requiring restart process, in other session processes, the second RSU or the management subsystem may terminate the session for some reason, at this time, the party terminating the session needs to initiate a log-out process to the other party, and a reason for terminating the connection needs to be marked.

Exemplarily, referring to fig. 11, a signaling interaction diagram is provided for the second RSU to initiate a LOGOUT request to the management subsystem, specifically, first, the second RSU sends a LOGOUT request (LOGOUT) to the V2X message access gateway (corresponding to 41 in fig. 11); after the V2X message access gateway receives the logout request sent by the second RSU, it forwards the logout request to the management subsystem (corresponding to 42 in fig. 11); after receiving the LOGOUT request forwarded by the V2X message access gateway, the management subsystem sends a LOGOUT request response (LOGOUT _ ACK) (corresponding to 43 and 44 in fig. 11) to the second RSU through the V2X message access gateway; after receiving the logout request response, the second RSU disconnects the connection of the Transmission Control Protocol (TCP) or the User Datagram Protocol (UDP) (corresponding to 45 in fig. 11).

The parameter extraction instruction is at least used for indicating the second RSU to report the configuration information to the management subsystem.

After the second RSU is in the login state, when an administrator needs to extract the operation information of the second RSU, the administrator may check the operation information through the management subsystem, specifically, the management subsystem may send a configuration acquisition request (CONFIG _ GET) to the second RSU through the V2X message access gateway, so that the second RSU reports its own working state or configuration parameters, such as location, signal strength, communication mode, service code, and the like.

Exemplarily, referring to fig. 12, a signaling interaction diagram is provided, in which a management subsystem requires a second RSU to report configuration information, specifically, the management subsystem first sends a configuration acquisition request (corresponding to 51 in fig. 12) to a V2X message access gateway; when the V2X message access gateway receives the configuration acquisition request sent by the management subsystem, it forwards the configuration acquisition request to the second RSU (corresponding to 52 in fig. 12); after receiving the configuration acquisition request, the second RSU processes the information carried in the configuration acquisition request, determines the information (corresponding to 53 in fig. 12) that needs to be reported to the management subsystem, and sends a configuration acquisition request reply (CONFIG _ GET _ ACK) (corresponding to 54 and 55 in fig. 12) carrying the determined information that needs to be reported to the management subsystem through the V2X message access gateway; and the management subsystem receives the information reported by the second RSU, displays and records the information (corresponding to 56 in fig. 12).

The reporting information policy instruction is at least used for instructing the second RSU to report the target information to the management subsystem according to a preset rule, and after receiving the reporting information policy instruction, the second RSU may report the target information to the second RSU management subsystem through the V2X message access gateway, where the target information at least includes: configuration information, alarm information and statistical information; specifically, when the second RSU detects a change in its configuration parameters or the second RSU management subsystem requires reporting of the configuration parameters, the second RSU may send configuration information to the V2X message access gateway; when the second RSU detects that the external state of the second RSU changes, the acquired information exceeds a set threshold value, a fault, a communication module is abnormal and a link is abnormal, the second RSU can send alarm information to the V2X message access gateway; the management subsystem can also make a strategy about reporting the statistical information by the second RSU, so that the second RSU can automatically report the statistical data in a preset period according to the requirement of the management subsystem, the statistical data comprises information such as a service use mark of the second RSU, and the statistical data can be cleared after the second RSU reports the target information successfully.

The remote control instruction is at least used for instructing the second RSU to execute an operation corresponding to the remote control instruction, and specifically, the management subsystem may send the remote control instruction carrying control restart or reset to the second RSU through the V2X message access gateway, and when receiving the remote control instruction, the second RSU gives a response and triggers a corresponding operation according to a requirement of the management subsystem.

The remote upgrade instruction is used for instructing the second RSU to upgrade the software of the second RSU.

Illustratively, referring to fig. 13, a signaling interaction diagram for the management subsystem to remotely upgrade the second RSU is provided, specifically, the management subsystem first sends a download notification (URL _ INFO) (corresponding to 61 in fig. 13) to the V2X message access gateway, and after receiving the download notification sent by the management subsystem, the V2X message access gateway sends the download notification (corresponding to 62 in fig. 13) to the second RSU; after receiving the download notification, the second RSU sends a download notification reply (URL _ INFO _ ACK) (corresponding to 63, 64 in fig. 13) to the management subsystem through the V2X message access gateway, and then downloads the file carried by the download notification through the third party upgrade server (corresponding to 65, 66, 67, 68, 69 in fig. 13); logging in again after downloading (corresponding to 70 in fig. 13), executing upgrading (corresponding to 71 in fig. 13) after logging in successfully, and reporting upgrading to the management subsystem through the V2X message access gateway (corresponding to 72 and 73 in fig. 13); after receiving the upgrade report, the management subsystem sends an upgrade report reply (corresponding to 74 and 76 in fig. 13) to the second RSU through the V2X message access gateway, and updates the upgrade status of the second RSU (corresponding to 75 in fig. 13).

In addition, when the first RSU needs to replace the SIM card, the first RSU needs to initiate a change request for changing the IMSI in the SIM card to the management subsystem again, so that the management subsystem updates the target mapping relationship, so optionally, as shown in fig. 14, after step S107, the method further includes: S1011-S1017:

s1011, V2X the message access gateway receives the IMSI change request sent by the first RSU.

The IMSI change request carries the changed IMSI, the sequence number, the target mapping relation and the registration identifier of the first RSU.

S1012, V2X the message access gateway sends an IMSI change request to the management subsystem.

And S1013, the management subsystem receives the IMSI change request sent by the V2X message access gateway.

S1014, the management subsystem updates the target mapping relation according to the changed IMSI, so that the updated target mapping relation is used for indicating the corresponding relation among the IMEI, the changed IMSI and the serial number.

S1015, the management subsystem sends an IMSI change response corresponding to the IMSI change request to the V2X message access gateway.

Wherein, the IMSI change response carries the updated target mapping relationship.

And S1016, the V2X message access gateway receives an IMSI change response corresponding to the IMSI change request sent by the management subsystem.

S1017, V2X the message access gateway sends an IMSI change response to the first RSU.

Further, in order to improve the registration efficiency, optionally, as shown in fig. 14, the above step S1012 may be replaced with steps S10211 to S10212:

the S10211, V2X message access gateway determines whether the sequence number carried by the IMSI change request is correct.

S10212, when the serial number is determined to be correct, the V2X message access gateway sends an IMSI change request to the management subsystem.

Further, since the management subsystem and the cloud platform where the first RSU is located also include some service subsystems, and the service subsystems are used to provide service support for the first RSU, after the first RSU is registered, the management subsystem also needs to notify the service subsystem of a message that the first RSU is registered, and optionally, as shown in fig. 15, step S105 may further include:

s1051, the management subsystem sends the target registration response to the V2X message access gateway.

S1052, the management subsystem sends a registration completion notification to the service subsystem of the first RSU.

The registration completion notification carries the sequence number, the target mapping relationship and the registration identifier.

It should be noted that, in this embodiment of the application, a communication protocol between the RSU and the V2X message access gateway belongs to an application layer protocol, and based on a TCP/Internet Protocol (IP) or UDP/IP layer, a protocol stack thereof is as shown in fig. 16, a protocol message between the RSU and the V2X message access gateway performs message interaction in a "request-response" manner, and for a request message sent by a requester, a responder must have and only has one response message as a reply; secondly, the protocol adopts the concept of session, and the RSU starts by sending a login request message to the V2X message access gateway, successfully logging in and authenticating and sending a successful login response message; the process is considered as a session process between the RSU and the V2X message access gateway until one end of the two communication parties initiates a logout request and the other end sends a logout response; in addition, the RSU is in an unregistered state, and cannot directly send uplink messages such as data and states to the cloud platform, and a login request must be initiated first, and the data can be sent to the cloud platform after a session is established successfully by login; in addition, in a session process, under the condition that there is no message interaction between the RSU and the V2X message access gateway, the RSU needs to periodically send a session state report to the V2X message access gateway to confirm that the RSU is in a session holding state; on the contrary, in the case of no message interaction, if the RSU does not send the session status report regularly, after the set time is exceeded, the V2X message access gateway considers that the session connection with the RSU is ended, and sends a logout request to the RSU.

In a session process of the RSU and the V2X message access gateway, if the RSU sends a new login request message to the management subsystem for some reason (for example, the RSU is restarted after power failure), the session is regarded as terminated, and meanwhile, the V2X message access gateway needs to immediately clear relevant information of the own party in the session process, and reprocess a new login request of the RSU according to a login process.

In addition, during one session between the RSU and the V2X message access gateway, if there is data communication between the RSU and the V2X message access gateway, it can be used as a judgment condition for RSU session maintenance, and after the RSU finishes the interaction with the V2X message access gateway, it must perform log-out operation to disconnect the session connection with the management subsystem.

In addition, due to reasons such as communication mode and processing failure, the communication between the RSU and the V2X message access gateway inevitably causes packet loss or overtime, so to ensure reliable transmission of data, a packet loss retransmission mechanism is adopted between the RSU and the V2X message access gateway; according to the packet loss and the occurrence frequency of timeout, the communication abnormity between the RSU and the V2X message access gateway can be divided into two cases: occasional anomalies and communication failures.

The sporadic abnormality mainly refers to the accidental, burst and non-continuous packet loss condition in the communication process between the RSU and the V2X message access gateway.

As shown in fig. 17, a signaling interaction process of data packet loss and retransmission between the RSU and the V2X message access gateway under the accidental abnormal condition is provided, specifically, as shown in fig. 17, when a session connection between the RSU and the V2X message access gateway is established, a data packet n containing a data request message of a requester is lost before reaching the responder in a communication process, if the requester does not receive a request response within a preset time period, whether to perform retransmission can be determined according to preset parameters, and if it is determined to perform retransmission, a message sequence number during retransmission is unchanged, but the number of retransmission times is increased incrementally; in addition, as shown in fig. 18, another signaling interaction process of data packet loss and retransmission between the RSU and the V2X message access gateway under the accidental abnormal condition is provided, specifically, as shown in fig. 18, when a session connection between the RSU and the V2X message access gateway is established, after a data request message of a requesting party reaches a responding party, a response message replied by the responding party is lost if the data request message does not reach the requesting party in the transmission process, and similarly, if the requesting party does not receive a request response within a preset time period, whether to perform retransmission or not may be determined according to preset parameters, a message sequence number during retransmission is unchanged, but the number of retransmission times is incremented.

As shown in fig. 19, when the requester retransmits overtime, the message sequence number in the data retransmission message of the requester should be the same as the message sequence number of the original message, so that the same request packet can be indicated, and meanwhile, the message retransmission times need to be updated according to the retransmission times; when the answering party receives the same message with the same message serial number from the same requesting party, the message is treated as the same message, the message serial number is kept the same when replying, and the message retransmission identification number is the same as the number in the treated request message retransmission identification when replying.

In addition, when packet loss, timeout continuously occurs or the ratio is large, the RSU and the V2X message access gateway are in a communication failure state, at this time, the party (which may be the RSU or the V2X message access gateway) that detects the communication failure first sends a LOGOUT message to the known peer IP, and reports the communication failure through the status word of the LOGOUT message. After the LOGOUT is sent by the requester, the requester releases the connection after receiving LOGOUT _ ACK or receiving overtime. If the LOGOUT message or LOGOUT _ ACK message is lost in the transmission process, the connection is released after the request party receives the LOGOUT _ ACK message overtime, and the response party can detect that the connection is invalid after no data packet is transmitted for a period of time; the RSU may then decide whether to reinitiate the connection again according to its own needs. In addition, after the communication failure is disconnected, the session connection between the RSU and the V2X message access gateway is also ended, and a new session connection must be started by initiating login from the RSU side.

For example, as shown in fig. 20, an embodiment of the present application further provides a signaling interaction diagram of a system architecture shown in fig. 3, where the method for managing a rsu provided by the foregoing embodiment is applied, and specific signaling content description may refer to description in the foregoing embodiment and is not repeated here.
