[0110] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings.

[0111] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0112] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for display, data for analysis, etc.) involved in this disclosure are all information and data authorized by the user or fully authorized by all parties.

[0113] See also Figure 1 , Figure 1 The present invention is a flowchart of a message communication processing method according to an exemplary embodiment. Specifically, the method can be applied to a sending end. The method may include the following steps:

[0114] Step S101, when a first original message content corresponding to any message to be sent is received, a first physical address of the first original message content is obtained.

[0115] In practical applications, the above-mentioned sending end may be a sending terminal of the message, such as a vehicle-mounted terminal, etc. The vehicle-mounted terminal may include a vehicle-mounted domain controller. Accordingly, the message communication processing method provided in the embodiment of the present application may be executed based on the vehicle-mounted domain controller.

[0116] In a specific embodiment, the first original message content corresponding to the message to be sent may be the first original message content corresponding to the message that the vehicle-mounted domain controller needs to send. In a specific embodiment, the first original message content may be control data. Exemplarily, the control data may be unmanned driving environment perception data streams such as power control data, brake control data, and steering control data. Specifically, the power control data may be engine speed and accelerator pedal position. The brake control data may be brake pedal position and brake pressure. The steering control data may be steering wheel data and steering torque. In a specific embodiment, the first original message content may be perception data. Exemplarily, the perception data may be millimeter wave radar data and lidar data.

[0117] In a specific embodiment, the message to be sent is a third encapsulated message, such as Figure 2 As shown, the above method also includes:

[0118] Step S201: encapsulate the first original message content based on the real-time publish-subscribe protocol at the application layer to obtain a first encapsulated message.

[0119] In a specific embodiment, the first encapsulated message includes a message header of a real-time publish-subscribe protocol and the first original message content. The message header of the real-time publish-subscribe protocol includes basic information such as protocol version, message type, sequence number, etc., which is used to identify and process the message.

[0120] Step S203, in the process of accessing the first preset memory based on the first preset original partition, based on the third preset configuration information, determine the second storage space from the first preset queue of the first preset memory, and store the first encapsulated message in the second storage space.

[0121] In a specific embodiment, the first preset raw partition is used to allocate the first preset memory to the first preset queue rawpktQ (raw packet queue) and the preset sending queue. Exemplarily, the first preset raw partition can be RAW (raw device) on the sending end side. In a specific embodiment, the first preset memory includes a first preset queue and a preset sending queue, and the first preset memory is mapped based on mmap (Memory Mapping) so that the first preset raw partition, the first user-mode driver and the first network card hardware can all access it. In a specific embodiment, the third preset configuration information is the virtual address of the first preset queue in the first preset memory. In a specific embodiment, the first preset queue is used to store messages to be sent. In a specific embodiment, the second storage space is any free storage space rawpktqe (rawpacket queue element) in the first preset queue.

[0122] In a specific embodiment, in the process of accessing the first preset memory based on the first preset original partition, based on the third preset configuration information, the second storage space is determined from the first preset queue of the first preset memory, and the first encapsulated message is stored in the second storage space. This can be based on the virtual address of the first preset queue in the first preset memory. The first preset original partition can access the first preset queue in the first preset memory, search for an idle second storage space in the first preset queue, and store the first encapsulated message in the second storage space.

[0123] Step S205: Record the first virtual address and the first memory address of the first encapsulated message in the second storage space.

[0124] In a specific embodiment, the first virtual information may be an address assigned by the operating system to the current message communication process, and the first virtual information includes a page directory index, a page table index, and an offset within a page. In a specific embodiment, the page directory index is used to find an item in the page directory, the page table index is used to find an item in the page table, and the offset within a page is used to locate data within a page.

[0125] Step S207: encapsulate the first encapsulated message in the second storage space based on the user datagram protocol at the transport layer to obtain a second encapsulated message.

[0126] In a specific embodiment, the second encapsulated message includes user datagram protocol port information, a message header of a real-time publish-subscribe protocol, and the first original message content. In a specific embodiment, the user datagram protocol port information is used to identify a specific application or service in the network, and each user datagram protocol port information is associated with a specific application or service. Through the user datagram protocol port information, it can be determined to which application or service the first encapsulated message should be delivered.

[0127] Step S209: encapsulate the second encapsulated message in the second storage space based on the Internet protocol at the network layer to obtain a third encapsulated message.

[0128] In a specific embodiment, the third encapsulated message includes an Internet Protocol address, a User Datagram Protocol port information, a message header of a Real-time Publish Subscribe Protocol, and the first original message content. In a specific embodiment, the Internet Protocol address is used to uniquely identify and locate each device in the Internet or a local area network. Through the Internet Protocol address, the second encapsulated message can be correctly routed to the target device.

[0129] In the above embodiments, the flexibility and efficiency of message transmission are improved through the layered encapsulation process. Application layer encapsulation ensures that the message format meets the protocol requirements, and further encapsulation of the transport layer and the network layer ensures that the message is transmitted safely and reliably in the network. Based on the virtual address of the first preset queue in the first preset memory, the first preset original partition can directly access the first preset queue and determine the second storage space, which helps to efficiently store the messages to be sent, thereby improving the utilization rate of the first preset memory and the flexibility of processing the messages to be sent, ensuring the reasonable allocation and efficient access of the first preset memory resources, and improving the integrity and performance of the transmission of the messages to be sent.

[0130] In a specific embodiment, the obtaining of the first physical address of the first original message content includes:

[0131] The first virtual address is converted into a first physical address.

[0132] In a specific embodiment, the first virtual address is converted into the first physical address by first obtaining a base address of a page table from a page directory using a page directory index of the first virtual address, then obtaining a base address of a page frame from a page table using a page table index of the first virtual address, and finally combining the page frame base address with the page offset of the first virtual address to calculate the final first physical address.

[0133] In the above embodiment, by converting the first virtual address into the first physical address, it is ensured that the actual first preset memory can be correctly accessed and operated. This conversion enables the first network card hardware to read the message to be sent from the first preset memory so as to correctly send the message to be sent, ensure that the content of the message to be sent is consistent with the actual message in the memory, and improve the accuracy and reliability of message transmission.

[0134] Step S103, in the process of accessing the first preset memory based on the first user mode driver, based on the first preset configuration information, a first storage space is determined from a preset sending queue of the first preset memory, and the first physical address is stored in the first storage space.

[0135] In a specific embodiment, the first preset configuration information is a virtual address of a preset sending queue in a first preset memory. In a specific embodiment, the preset sending queue is a memory area for storing and managing basic information of received messages to be sent. In a specific embodiment, the first storage space is any free storage space in the preset sending queue.

[0136] In a specific embodiment, in the process of accessing the first preset memory based on the first user state driver, based on the first preset configuration information, the first storage space is determined from the preset sending queue of the first preset memory, and the first physical address is stored in the first storage space, which can be based on the virtual address of the preset sending queue in the first preset memory. The first user state driver can access the preset sending queue in the first preset memory, search for the free first storage space in the preset sending queue, and place the first physical address in the first storage space, thereby changing the first storage space from an idle state to an occupied state.

[0137] Step S105, in the process of accessing the first preset memory based on the first network card hardware, when it is detected that any free storage space in the preset sending queue is occupied, based on the second preset configuration information, the first storage space is taken out from the preset sending queue, the first storage space is parsed, and the first physical address is obtained.

[0138] In a specific embodiment, the second preset configuration information is the physical address of the preset sending queue in the first preset memory.

[0139] In a specific embodiment, in the above-mentioned process of accessing the first preset memory based on the first network card hardware, when it is detected that any free storage space in the preset sending queue is occupied, based on the second preset configuration information, the first storage space is taken out from the preset sending queue, and the first storage space is parsed to obtain the first physical address, which can be based on the physical address of the preset sending queue in the first preset memory. The first network card hardware can access the preset sending queue in the first preset memory. When it is detected that any free storage space in the preset sending queue is occupied, the occupied first storage space is taken out from the preset sending queue and parsed to obtain the first physical address.

[0140] Step S107: Send the message to be sent based on the first physical address and the first network card hardware.

[0141] In a specific embodiment, Figure 3 As shown, the sending of the message to be sent based on the first physical address and the first network card hardware includes:

[0142] Step S301, in a process of accessing a first preset memory based on first network card hardware, obtaining a first memory address based on fourth preset configuration information and a first physical address.

[0143] In a specific embodiment, the fourth preset configuration information is the physical address of the first preset queue in the first preset memory.

[0144] In a specific embodiment, in the process of accessing the first preset memory based on the first network card hardware, based on the fourth preset configuration information and the first physical address, obtaining the first memory address can be based on the physical address of the first preset queue in the first preset memory. The first network card hardware can access the first preset queue in the first preset memory, and based on the first physical address of the second storage space of the message to be sent in the first preset queue, obtain the first memory address of the second storage space of the message to be sent in the first preset queue.

[0161] Step S401: when any message to be received is received, a second physical address of the message to be received is obtained.

[0162] In practical applications, the above-mentioned receiving end may be a receiving terminal for the message, such as a vehicle-mounted terminal, etc. The vehicle-mounted terminal may include a vehicle-mounted domain controller. Accordingly, another message communication processing method provided in an embodiment of the present application may be executed based on the vehicle-mounted domain controller.

[0163] In a specific embodiment, the above-mentioned message to be received may be a message that the vehicle-mounted domain controller needs to receive. In a specific embodiment, the above-mentioned message to be received may be control data.

[0164] In a specific embodiment, the obtaining of the second physical address of the message to be received includes:

[0165] In the process of accessing the second preset memory based on the second network card hardware, based on the seventh preset configuration information and the second preset controller, a fourth storage space is determined from the second preset queue of the second preset memory, and the message to be received is stored in the fourth storage space;

[0166] The second physical address of the message to be received in the fourth storage space is recorded.

[0167] In a specific embodiment, the second preset memory includes a second preset queue rawpktQ (rawpacket queue) and a preset receive queue RQ (receive queue), and the second preset memory is mapped based on mmap (Memory Mapping) so that the second pre-raw partition, the second user-mode driver and the second network card hardware can all access it. In a specific embodiment, the seventh preset configuration information is the physical address of the second preset queue in the second preset memory. In a specific embodiment, the second preset controller is used to directly transfer data between the memory and the peripherals in the computer system.

[0168] In a specific embodiment, the second preset queue is used to store messages to be received. In a specific embodiment, the fourth storage space is any free storage space rawpktqe (rawpacket queue element) in the second preset queue.

[0169] In a specific embodiment, in the process of accessing the second preset memory based on the second network card hardware, based on the seventh preset configuration information and the second preset controller, the fourth storage space is determined from the second preset queue of the second preset memory, and the message to be received is stored in the fourth storage space. It can be based on the physical address of the second preset queue in the second preset memory. The second network card hardware can access the second preset queue in the second preset memory, search for an idle fourth storage space in the second preset queue, and store the message to be received in the fourth storage space.

[0170] In the above embodiment, through the physical address of the second preset queue in the second preset memory, the second network card hardware can directly access the second preset memory, determine the fourth storage space in the second preset queue, and ensure that the message to be received is correctly stored in the appropriate storage location. In addition, the message is stored in the free storage space in the second preset queue, which optimizes the use of the second preset memory. Selecting the free storage space avoids conflicts and overwriting of messages to be received, and improves the efficiency of the second preset memory management. Recording the second physical address of the message to be received in the fourth storage space provides the necessary information for the subsequent processing of the message, which can quickly locate the position of the message to be received in the subsequent processing stage, reduce the search time, and improve the system processing efficiency.

[0171] Step S403, in the process of accessing the second preset memory based on the second network card hardware, based on the fifth preset configuration information, determine the third storage space from the preset receiving queue of the second preset memory, and store the second physical address in the third storage space.

[0172] In a specific embodiment, the fifth preset configuration information is a physical address of the preset receiving queue in the second preset memory. In a specific embodiment, the preset receiving queue is a memory area for storing and managing basic information of received messages to be received. In a specific embodiment, the third storage space is any free storage space RQE (receive queue element) in the preset receiving queue.

It can be based on the physical address of the preset receive queue in the second preset memory. The second network card hardware can access the preset receive queue in the second preset memory, search for an idle third storage space in the preset receive queue, and place the second physical address in the third storage space, thereby changing the third storage space from an idle state to an occupied state.

[0174] Step S405, in the process of accessing the second preset memory based on the second user mode driver, when it is detected that any free storage space in the preset receiving queue is occupied, based on the sixth preset configuration information, the third storage space is taken out from the preset receiving queue, the third storage space is parsed, and the second physical address is obtained.

[0175] In a specific embodiment, the sixth preset configuration information is a virtual address of the preset receiving queue in the second preset memory.

[0176] In a specific embodiment, in the process of accessing the second preset memory based on the second user state driver, when it is detected that any free storage space in the preset receive queue is occupied, based on the sixth preset configuration information, the third storage space is taken out from the preset receive queue, and the third storage space is parsed to obtain the second physical address, which can be a virtual address based on the preset receive queue in the second preset memory. The second user state driver can access the preset receive queue in the second preset memory. When it is detected that any free storage space in the preset receive queue is occupied, the occupied third storage space is taken out from the preset receive queue and parsed to obtain the second physical address.

[0177] Step S407: Based on the second physical address and the second preset original partition, obtain the second original message content corresponding to the message to be received.

[0178] In a specific embodiment, the above method further includes:

[0183] Based on the second memory address, the message to be received is taken out from the fourth storage space, and the message to be received is decapsulated to obtain the second original message content.

[0184] In a specific embodiment, the above-mentioned conversion of the second physical address into the second virtual address can be as follows: first, the page table of the current process is obtained, and the page table records the mapping relationship between the virtual address and the physical address. Then, the physical address is used to find the page table entry, and the page table entry stores the mapping relationship between the virtual address and the physical address. The physical address usually needs to be converted into a corresponding page table index in order to find the corresponding page table entry from the page table. Secondly, according to the mapping information in the page table entry, the virtual address is calculated. The mapping usually includes the address mapping of the page directory and the page table, and the final virtual address is obtained in combination with the offset in the page table entry.

[0185] In a specific embodiment, the second preset original partition is used to allocate the second preset memory to the second preset queue and the preset receiving queue. Exemplarily, the second preset original partition can be a RAW (raw device, original partition) on the receiving end side. In a specific embodiment, the eighth preset configuration information is a virtual address of the second preset queue in the second preset memory.

[0186] In a specific embodiment, in the process of accessing the second preset memory based on the second preset original partition, based on the eighth preset configuration information and the second virtual address, the second memory address obtained can be a virtual address based on the second preset queue in the second preset memory, and the second preset original partition can access the second preset queue in the second preset memory, and based on the second virtual address of the message to be received in the third storage space of the second preset queue, the second memory address of the message to be received in the fourth storage space of the second preset queue is obtained.

[0187] In the above embodiment, by converting the second physical address into the second virtual address, the message to be received can be located in the second preset memory space, and the second memory address of the message to be received is recorded in the fourth storage space, so that the subsequent processing steps can accurately find and operate the message to be received. In addition, based on the virtual address of the second preset queue in the second preset memory, the second preset original partition can directly access the second preset memory, thereby obtaining the message to be received in the second preset memory, reducing the overhead of intermediate conversion and improving the efficiency of message transmission.

[0188] In a specific embodiment, the above method further includes:

[0189] Obtaining a second message length of the message to be received;

[0190] The method of obtaining the second memory address based on the eighth preset configuration information and the second virtual address includes:

[0194] In the above embodiment, based on the second virtual address and the second message length of the message to be received, double protection can be provided. In case the second virtual address is not fully obtained, the second memory address of the message to be received in the second preset memory can be accurately located to ensure that the message to be received is read correctly.

[0195] In a specific embodiment, the second original message content is a third decapsulated message, and the decapsulation process is performed on the message to be received, and the second original message content obtained includes:

[0197] Decapsulating the first decapsulated message at the transport layer to obtain a second decapsulated message;

[0198] The second desealed message is desealed at the application layer to obtain a third desealed message.

[0199] In a specific embodiment, the first unsealed message is a to-be-received message with the Internet Protocol address removed.

[0200] In a specific embodiment, the second unsealed message is a message to be received without information including an Internet Protocol address and a User Datagram Protocol port.

[0201] In a specific embodiment, the third unsealed message is a to-be-received message with the Internet Protocol address, User Datagram Protocol port information, and Real-time Publish Subscribe Protocol message header removed.

[0202] In the above embodiment, through the layer-by-layer decapsulation process, the header information of each layer of the protocol can be gradually stripped from the network layer, the transport layer to the application layer, and the message closest to the user's needs can be accurately extracted. The decapsulation step of each layer ensures that the message is correctly decoded according to the protocol specification, thereby reducing the risk of message damage or parsing errors.
