Description

Technical Field

[0001] The present application relates to the technical field of electric vehicles, and in particular to a vehicle communication traffic processing method, device, cockpit, vehicle and storage medium. Background Art

[0002] As vehicle intelligence technology continues to improve, the vehicle's smart cockpit can provide Internet access services. At present, the Internet traffic in most vehicles' cockpits can be divided into entertainment traffic and system traffic. Among them, the system traffic generated by vehicle navigation and vehicle system-level application Internet access is paid by the vehicle manufacturer; the entertainment traffic generated by entertainment APP (Application), such as music APP and video APP Internet access, is paid by the user.

[0003] See also Figure 1 , is a schematic diagram of realizing traffic differentiation in the related art. The Ethernet port eth0 of the vehicle's CDU (Central Display Unit) is assigned two IP addresses (for example, 192.168.2.1 and 192.168.2.2 respectively). The system selects the export IP address according to the uid (user identifier) ​​of the application in the TCP / IP (Transmission Control Protocol / Internet Protocol) protocol stack. The TBOX (Telemtrics Box, on-board communication module) side forwards the message to different APN (Access Point Name) exports to access the external network, for example, forwarding to APN1 or APN2 according to the export IP address.

[0004] When the hotspot is turned on on the large central control screen in the cockpit, after other devices are connected to the large screen hotspot, source address conversion is required when they access the Internet through CDU and TBOX. That is to say, all messages going out of the CDU must have their source addresses set to 192.168.2.1 or 192.168.2.2 according to the relevant firewall settings. At this time, all apps on the CDU and devices connected to the CDU can only access the Internet through one APN exit, for example, all through the source address 192.168.2.1 to access the Internet, that is, through the system traffic channel to access the Internet, and the vehicle manufacturer pays for the system traffic generated, or all through the source address 192.168.2.2 to access the Internet, that is, through the entertainment traffic channel to access the Internet, and the user pays for the entertainment traffic generated. In this way, the original traffic allocation rules are changed, and traffic may be stolen, resulting in disputes over traffic costs. For example, the OTA (Over The Air) of a vehicle generally requires Internet access through the system traffic channel. At this time, when the hotspot is turned on on the large screen in the cockpit, the user may access the Internet through the entertainment traffic channel, causing the user to pay the OTA traffic fee. OTA traffic is huge, so the vehicle manufacturer generally pays the OTA traffic fee. The above situation is likely to lead to disputes over traffic fees, cause user complaints, and affect the user's Internet experience. Summary of the invention

[0050] Related technologies When the hotspot is turned on on the large central control screen in the cockpit, the original traffic allocation rules are changed, which may lead to traffic leakage and traffic fee disputes. For example, the vehicle's OTA accesses the Internet through the entertainment traffic channel, which leads to traffic fee disputes, user complaints, and affects the user's Internet experience.

[0051] In response to the above problems, an embodiment of the present application provides a vehicle communication traffic processing method, which can avoid traffic theft, reduce traffic fee disputes, and improve the user's Internet experience.

[0052] The technical solution of the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0053] Figure 2 It is a first flow chart of the vehicle communication traffic processing method shown in an embodiment of the present application.

[0054] like Figure 2 As shown, the method includes:

[0055] Step 201, when it is detected that a hotspot is turned on in a vehicle cabin, a first message for accessing an external network sent by an application in the vehicle cabin and a second message for accessing an external network sent by a device connected to the hotspot are obtained.

[0056] Among them, obtaining the second message sent by the device connected to the hotspot for accessing the external network may include: after identifying that the device connected to the hotspot requests access to the external network, obtaining the second message sent by the device through the PREROUTING chain of the firewall for accessing the external network.

[0057] Step 202, access the external network according to the historically configured communication channel by acquiring the first message sent by the application in the vehicle cabin for accessing the external network, the historically configured communication channel includes a first communication channel and a second communication channel, wherein the first communication channel is a non-system traffic channel, and the second communication channel is a system traffic channel.

[0058] The method of acquiring a first message sent by an application program in a vehicle cabin for accessing an external network and accessing the external network according to a historically configured communication channel may include:

[0059] In the case where the in-cabin application includes vehicle navigation and a system-level application of the vehicle, the first message sent by the in-cabin application for accessing the external network is obtained, and the external network is accessed through the second communication channel (system traffic channel);

[0060] In the case where the in-cabin application includes an entertainment APP, the first message sent by the in-cabin application for accessing the external network is obtained, and the external network is accessed according to the first communication channel (non-system traffic channel).

[0061] In this way, the original traffic zone mode in the cockpit can be kept intact. For example, vehicle navigation and vehicle system-level application Internet access still belong to system traffic, and the traffic fee is paid by the vehicle manufacturer; entertainment APP (Application), such as music APP and video APP Internet access, still belong to entertainment traffic, and the traffic fee is paid by the user.

[0062] Step 203: Access the external network through the first communication channel using the second message sent by the device connected to the hotspot for accessing the external network.

[0063] This step 203 may include:

[0064] Setting a preset identifier for a second message sent by the device connected to the hotspot for accessing an external network;

[0065] Convert the source address of the second message after the preset identifier is set, so that the converted source address corresponds to the source address of the first communication channel;

[0066] The second message after the source address translation is accessed to the external network through the first communication channel.

[0067] The step of setting a preset identifier for the acquired second message sent by the device connected to the hotspot for accessing the external network may include:

[0068] After the second message for accessing the external network sent by the device connected to the hotspot passes through the FORWARD chain of the firewall, it jumps to the first custom chain;

[0069] A preset identifier is set for the second message in the first custom chain.

[0070] The step of performing source address conversion on the second message after the preset identifier is set so that the converted source address corresponds to the source address of the first communication channel may include:

[0071] The second message after setting the preset identifier passes through the POSTROUTING chain of the firewall and then jumps to the second custom chain;

[0072] In the second custom chain, according to the preset identifier, the source address of the second message is converted so that the converted source address corresponds to the source address of the first communication channel.

[0073] It should be noted that step 202 and step 203 can be executed simultaneously without a necessary order relationship.

[0074] Through this embodiment, it can be found that in the technical solution of the present application, when it is detected that the hotspot in the vehicle cockpit is turned on, the first message sent by the application in the vehicle cockpit for accessing the external network is obtained, and the external network is accessed according to the historically configured communication channel. The historically configured communication channel includes a first communication channel and a second communication channel, wherein the first communication channel is a non-system traffic channel and the second communication channel is a system traffic channel; the second message sent by the device connected to the hotspot for accessing the external network is obtained, and the external network is accessed according to the first communication channel. Through the above processing, when the hotspot in the vehicle cockpit is turned on, the present application maintains the original traffic distribution method of the cockpit unchanged, and sets the Internet access method of the device connected to the hotspot to access the Internet through the non-system traffic channel, which can prevent all APPs from accessing the Internet through the system traffic channel or all through the non-system traffic channel. In this way, when the hotspot in the vehicle cockpit is turned on, traffic stealing can be avoided, and the vehicle's OTA can be prevented from accessing the Internet through the non-system traffic channel, thereby reducing traffic fee disputes and improving the user's Internet experience.

[0075] Figure 3 It is a second flow chart of the vehicle communication traffic processing method shown in an embodiment of the present application.

[0076] like Figure 3 As shown, the method includes:

[0077] Step 301, when it is detected that a hotspot is turned on in a vehicle cabin, a first message for accessing an external network sent by an application in the vehicle cabin is obtained.

[0078] Step 302 , access the external network according to the historically configured communication channel using the first message sent by the in-cabin application program for accessing the external network. The historically configured communication channel includes an entertainment traffic channel and a system traffic channel.

[0079] In this step, when the in-cabin application includes vehicle navigation and vehicle system-level application, the first message for accessing the external network sent by the in-cabin application is obtained, and the external network is accessed according to the system traffic channel;

[0080] In the case where the in-cabin application includes an entertainment APP, the first message for accessing the external network sent by the in-cabin application is obtained, and the external network is accessed according to the entertainment traffic channel.

[0081] In this way, the original traffic zone mode in the cockpit can be kept intact. For example, vehicle navigation and vehicle system-level application Internet access still belong to system traffic, and the traffic fee is paid by the vehicle manufacturer; entertainment APP (Application), such as music APP and video APP Internet access, still belong to entertainment traffic, and the traffic fee is paid by the user.

[0082] The cockpit Internet access paths involved in step 301 and step 302 can be simultaneously referred to Figure 4 As shown in the dotted box 2 circled in the figure. Figure 4 It is a schematic diagram of the application framework of the vehicle communication traffic processing method shown in the embodiment of the present application.

[0083] Step 303, when it is detected that the hotspot in the vehicle cabin is turned on, a second message for accessing an external network sent by a device connected to the hotspot is obtained.

[0084] It should be noted that step 301 and step 303 can be executed simultaneously without a necessary order relationship.

[0085] Also see Figure 4 In step 303, after identifying that the device connected to the hotspot requests to access the external network, the second message for accessing the external network sent by the device through the PREROUTING chain of the firewall can be obtained. If the device connected to the hotspot, such as a mobile phone, is not accessing the local device, it means that it is requesting to access the external network, so the message can be forwarded to the FORWARD chain.

[0086] Figure 4 In the above diagram, the PREROUTING chain, INPUT chain, FORWARD chain, OUTPUT chain, and POSTROUTING chain are all firewall chains. The forwarding path of the message sent by the device connected to the hotspot through the hotspot is as follows: Figure 4 As shown in the solid line frame 1, the cockpit Internet access path is as follows Figure 4 As shown in the dotted box 2 circled in the figure.

[0087] It should be noted that iptables rules are a configuration method of the Linux firewall system, which is used to set, maintain and check the IP packet filtering rules of the Linux kernel. Iptables rules can control the entry, exit and forwarding of network data packets, and realize the management and security protection of network traffic. Iptables rules can include four tables, namely filter (filter table), nat (address translation table), mangle (modification table) and raw (tracking table), each of which has different functions and scopes. To convert the source address through iptables rules, nat (address translation table) can be mainly used.

[0088] Generally, you can use the "nat table" of iptables to set nat rules. The nat table can include multiple chains: PREROUTING chain, INPUT chain, FORWARD chain, OUTPUT chain, and POSTROUTING chain. Among them, you can select the appropriate chain to add rules according to user needs.

[0089] Step 304: Set a preset identifier for the acquired second message sent by the device connected to the hotspot for accessing the external network.

[0090] Step 304 may include:

[0091] Step 3041, after the second message for accessing the external network sent by the device connected to the hotspot passes through the FORWARD chain of the firewall, it jumps to the first custom chain.

[0092] In order to solve the problem of traffic leakage when the cockpit hotspot is turned on, this application adds the following rules to the cockpit network firewall but is not limited to this.

[0093] For example, add a jump rule to the FORWARD chain as follows:

[0094] iptables -t mangle -A FORWARD -j tetherctrl_mangle_FORWARD.

[0095] The function of the jump rule is to jump to the first custom chain. This application adds a jump rule in the FORWARD chain of iptables, according to which all messages passing through the FORWARD chain can be jumped to a custom chain named "tetherctrl_mangle_FORWARD" for further processing, which can be called the first custom chain.

[0096] Step 3042: Set a preset identifier for the second message in the first custom chain.

[0097] In this step, all messages passing through the tetherctrl_mangle_FORWARD table are set with a preset mark in the first custom chain, such as a preset label or other form of mark. The preset label may be, for example, mark 0x1000 but is not limited thereto:

[0098] iptables -t mangle -A tetherctrl_mangle_FORWARD -i wlan0 -j MARK --set -xmark 0x1000.

[0099] Among them, wlan0 is a network port used to connect to a mobile terminal such as a mobile phone.

[0100] The purpose of this iptables command is to mark all packets passing through the "tetherctrl_mangle_FORWARD" table with a specific mark, such as "mark 0x1000" but not limited to this, and can also be other marks. This mark can be used for subsequent packet processing, such as policy routing or packet filtering.

[0101] Step 305 , performing source address conversion on the second message after the preset identifier is set, so that the converted source address corresponds to the source address of the entertainment traffic channel.

[0102] Step 305 may include:

[0103] Step 3051, after the second message with the preset identifier is set passes through the POSTROUTING chain of the firewall, and then jumps to the second custom chain.

[0104] In this step, you can add the following redirection rules to the POSTROUTING chain:

[0105] iptables -t nat -A POSTROUTING -j tetherctrl_nat_POSTROUTING.

[0106] The purpose of this jump rule is to jump to the second custom chain. The purpose of this iptables command is to add a jump rule in the "POSTROUTING" chain. According to this jump rule, all messages passing through this chain can be jumped to a custom chain named "tetherctrl_nat_POSTROUTING" for processing. This custom chain can be called the second custom chain.

[0107] Step 3052: In the second custom chain, the source address of the second message is converted according to the preset identifier, so that the converted source address corresponds to the source address of the entertainment traffic channel.

[0108] In this step, the second custom chain performs source address translation on the second message according to the above-mentioned label "mark 0x1000", that is, performs source address translation on all hotspot traffic:

[0109] iptables -t nat -A tetherctrl_nat_POSTROUTING -o eth0 -m mark--mark0x1000-j MASQUERADE.

[0110] The purpose of this iptables command is to convert the source address of all hotspot traffic passing through the "tetherctrl_nat_POSTROUTING" table in the second custom chain according to the previously added label (mark0x1000), so that the converted source address corresponds to the source address of the entertainment traffic channel, so that they can access the external network normally through the Ethernet port (eth0 network port).

[0111] Through the above processing, the embodiment of the present application performs source address conversion on all traffic passing through the cabin hotspot, but does not affect the original traffic differentiation logic.

[0112] Step 306: The second message after the source address translation is accessed to the external network through the entertainment traffic channel.

[0113] After translating the source address of all hotspot traffic passing through the "tetherctrl_nat_POSTROUTING" table in the previous step, the second message after the source address translation can access the external network through the entertainment traffic channel, that is, it can access the external network normally through the Ethernet port (eth0 network port).

[0114] Through this embodiment, it can be found that in the related technology, when the hotspot is turned on in the cockpit, all messages passing through the POSTROUTING chain are subjected to source address conversion. The embodiment of the present application only converts the source address of the messages marked with a label in the FORWARDING chain, and does not affect the original CDU Internet access channel. This prevents all APPs on the large screen from using entertainment traffic or system traffic after the hotspot is turned on. Only the traffic using the hotspot is set to use entertainment traffic. The original traffic differentiation scheme of the cockpit is not affected, which avoids the behavior of stealing traffic in some environments, such as avoiding the situation where OTA traffic uses entertainment traffic, thereby reducing disputes over traffic costs and improving the user's Internet experience.

[0115] The vehicle communication traffic processing method of the present application is introduced in detail above, and the embodiments of the present application correspondingly provide a vehicle communication traffic processing device, a vehicle cabin and a car.

[0116] Figure 5 It is a first structural schematic diagram of a vehicle communication traffic processing device shown in an embodiment of the present application.

[0117] like Figure 5 As shown, the vehicle communication traffic processing device 50 provided in the present application includes: a message acquisition module 51, a first processing module 52, and a second processing module 53.

[0118] The message acquisition module 51 is used to acquire a first message sent by an application in the vehicle cabin for accessing an external network and a second message sent by a device connected to the hotspot for accessing an external network when detecting that a hotspot is turned on in the vehicle cabin.

[0119] After identifying that the device connected to the hotspot requests to access the external network, the message acquisition module 51 may acquire a second message for accessing the external network sent by the device through the PREROUTING chain of the firewall.

[0120] The first processing module 52 is used to access the external network through a historically configured communication channel for acquiring a first message sent by an application program in the vehicle cabin for accessing the external network. The historically configured communication channel includes a first communication channel and a second communication channel, wherein the first communication channel is a non-system traffic channel and the second communication channel is a system traffic channel.

[0121] The first processing module 52 may access the external network through the second communication channel (system traffic channel) for the first message sent by the vehicle in-cabin application for accessing the external network when the vehicle in-cabin application includes vehicle navigation and vehicle system-level application;

[0122] In the case where the in-cabin application includes an entertainment APP, the first message sent by the in-cabin application for accessing the external network is obtained, and the external network is accessed according to the first communication channel (non-system traffic channel).

[0123] The second processing module 53 is used to access the external network through the first communication channel based on the second message for accessing the external network sent by the device connected to the hotspot.

[0124] The second processing module 53 can set a preset identifier for the second message sent by the device connected to the hotspot for accessing the external network; perform source address conversion on the second message after the preset identifier is set, so that the converted source address corresponds to the source address of the first communication channel; and access the external network through the first communication channel for the second message after the source address conversion.

[0125] The device provided by the present application, when detecting that a hotspot is turned on in the vehicle cockpit, accesses the external network through a historically configured communication channel for a first message sent by an application in the vehicle cockpit for accessing an external network, wherein the historically configured communication channel includes a first communication channel and a second communication channel, wherein the first communication channel is a non-system traffic channel and the second communication channel is a system traffic channel; and accesses the external network through the first communication channel for a second message sent by a device connected to the hotspot for accessing an external network. Through the above processing, when the hotspot is turned on in the vehicle cockpit, the present application maintains the original traffic allocation method of the cockpit unchanged, and sets the Internet access method of the device connected to the hotspot to access the Internet through a non-system traffic channel, which can prevent all APPs from accessing the Internet through the system traffic channel or all through the non-system traffic channel. In this way, when the hotspot is turned on in the vehicle cockpit, traffic stealing can be avoided, and the vehicle's OTA can be prevented from accessing the Internet through a non-system traffic channel, thereby reducing disputes over traffic charges and improving the user's Internet experience.

[0126] Figure 6 It is a second structural schematic diagram of the vehicle communication traffic processing device shown in an embodiment of the present application.

[0127] like Figure 6 As shown, the vehicle communication traffic processing device 50 provided in the present application includes: a message acquisition module 51, a first processing module 52, and a second processing module 53.

[0128] The functions of the message acquisition module 51, the first processing module 52, and the second processing module 53 can be found in Figure 5 Described in .

[0129] In one embodiment, the second processing module 53 may include: an identification submodule 531 , an address conversion submodule 532 , and an access submodule 533 .

[0130] The identification submodule 531 is used to set a preset identification for the second message sent by the device connected to the hotspot for accessing the external network.

[0131] The identification submodule 531 can jump the second message for accessing the external network sent by the device connected to the hotspot to the first custom chain after passing through the FORWARD chain of the firewall; and set a preset identifier for the second message in the first custom chain.

[0132] The address conversion submodule 532 is used to convert the source address of the second message after the preset identifier is set, so that the converted source address corresponds to the source address of the first communication channel.

[0133] The address conversion submodule 532 can jump the second message after setting the preset identifier through the POSTROUTING chain of the firewall to the second custom chain; in the second custom chain, the source address of the second message is converted according to the preset identifier, so that the converted source address corresponds to the source address of the first communication channel.

[0134] The access submodule 533 is used to allow the second message after the source address translation to access the external network through the first communication channel.

[0135] The device provided in the present application only performs source address conversion on the messages labeled in the FORWARDING chain, without affecting the original CDU Internet access channel. This prevents all APPs on the large screen from using entertainment traffic or system traffic after the hotspot is turned on. Only the traffic using the hotspot is set to use entertainment traffic, and the original traffic differentiation scheme of the cockpit is not affected. This avoids traffic stealing in some environments, such as preventing OTA traffic from using entertainment traffic, thereby reducing disputes over traffic charges and improving users' Internet experience.
