[0002] With the sweeping wave of intelligentization and connectivity, automobiles have evolved from simple means of transportation into "mobile intelligent terminals" integrating information perception, communication interaction, and entertainment services. However, our increasing reliance on in-vehicle networks has created a sharp contradiction with the "blind spots" and "weaknesses" of wireless network coverage in reality. Whether speeding across the vast Gobi Desert or navigating urban canyons congested with base stations, users may face wireless network connection interruptions due to factors such as incomplete operator network coverage, geographical obstructions, and performance failures of in-vehicle equipment. These interruptions can cause numerous inconveniences for users, such as navigation malfunctions, entertainment disruptions, information silos, and even threats to driving safety. Summary of the Invention

Thus, in the event of a wireless network interruption for the first vehicle terminal, a data transmission path can be established with the second vehicle terminal via the direct link to reconnect to the wireless network, thereby extending and sharing the wireless network.

[0033] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0034] In various embodiments of the present invention, it should be understood that the sequence number of each process described below does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0035] In addition, the terms "system" and "network" are often used interchangeably in this article.

[0036] The terms "first," "second," etc., used in the specification and claims of this invention are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same class, not limited in number; for example, the first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0037] Before providing a detailed description of the embodiments of the present invention, the following related concepts will be explained:

[0038] Cellular Vehicle-to-Everything (C-V2X) technology, derived from V2V direct connection technology, can achieve direct communication based on cellular technology. Its design includes low-latency, highly reliable vehicle-to-vehicle and vehicle-to-infrastructure direct communication capabilities. This means that there are no fundamental technical obstacles to achieving basic data interoperability between vehicles, laying a solid protocol foundation for building a shared wireless network.

[0039] Moreover, pre-installed C-V2X communication modules have become standard equipment in many vehicle models. These modules integrate the antennas, RF chips, and processing units required for direct V2V connections, possessing the hardware potential for wireless network sharing. From an industry ecosystem perspective, chip manufacturers, equipment suppliers, OEMs, and telecom operators have formed a close-knit industry alliance, jointly promoting the implementation of C-V2X technology. The widespread adoption of hardware platforms and the continuous decline in costs have made large-scale deployment of V2V wireless network sharing functionality economically feasible at the hardware level.

[0040] The application system of the vehicle wireless network connection method described in this embodiment of the invention, hereinafter referred to as the vehicle wireless network connection system, can implement not only the vehicle wireless network connection method applied to a first vehicle terminal and / or a second vehicle terminal, but also any of the following methods:

[0041] Identity authentication and connection establishment method: Before the first vehicle terminal and the second vehicle terminal access the wireless network, the first vehicle terminal and the second vehicle terminal can authenticate their identities with a trusted management center through a cellular network or roadside unit and obtain temporary communication credentials for accessing the wireless network. In subsequent interactions between the first vehicle terminal and the second vehicle terminal, identity authentication can be performed based on the corresponding temporary communication credentials.

[0042] Dynamic networking and route discovery method: When the wireless network connection of the first vehicle terminal is interrupted, a network sharing request is broadcast through the V2V channel; the second vehicle terminal (hotspot source) that receives the network sharing request and accesses the wireless network responds, or performs multi-hop relay through intermediate vehicle terminals, and automatically forms a temporary V2V data transmission path;

[0043] Data relay and hotspot sharing method: The second vehicle terminal provides wireless network access service to the first vehicle terminal through the established V2V data transmission path. The data can be encrypted end-to-end throughout the transmission process to ensure user privacy and communication security.

[0044] Incentive Mechanisms and Settlement Methods: Mechanisms such as blockchain or credit scores can be introduced to reward the second vehicle terminal that provides network resources (e.g., data vouchers, service fees, credit scores), forming a virtuous cycle of "one for all, all for one". In terms of business models, in addition to the aforementioned blockchain or credit score system, OEMs can package and sell it as a value-added service, while operators can view it as an effective means to expand network coverage and increase user stickiness.

[0045] See Figure 1 This invention provides a wireless network connection method for a vehicle, applied to a first vehicle terminal. For example, the first vehicle terminal is a communication device that supports cellular technology or direct communication between devices / terminal pass-through / device-to-device technology, etc. Specifically, the first vehicle terminal is a communication device that supports C-V2X technology.

[0046] Furthermore, the method includes:

[0047] Step 101: Broadcast a network sharing request via the direct link;

[0048] In this embodiment of the invention, the Sidelink supports C-V2X technology for device-to-device communication, allowing direct data exchange between vehicle terminals.

[0049] The network sharing request sent by the first vehicle terminal can be understood as a connection request to connect to a "vehicle hotspot." Here, a "vehicle hotspot" refers to sharing a wireless network connection with other communication devices through the vehicle terminal. The first vehicle terminal can be understood as the requester of the "vehicle hotspot."

[0050] Step 102: Receive the network sharing response sent by the second vehicle terminal in response to the network sharing request;

[0051] In this embodiment of the invention, the second vehicle terminal can be understood as a sharer of the "vehicle hotspot".

[0052] The network sharing response includes an allow sharing response or a deny sharing response.

[0053] Step 103: If the network sharing response is an enable sharing response, establish a data transmission path with the second vehicle terminal and access the wireless network through the data transmission path.

[0054] In this embodiment of the invention, when the network sharing response is an enable sharing response, it means that the first vehicle terminal and the second vehicle terminal have successfully established a data transmission path. Through the data transmission path and the second vehicle terminal, the first vehicle terminal can access the wireless network.

[0055] It should be noted that, if the network sharing response is a rejection response, the method further includes:

[0056] Based on the rejection information and / or suggestion information of the rejection response, adjust the network sharing request to obtain the adjusted network sharing request;

[0057] Send the adjusted network sharing request to attempt to reconnect to the wireless network.

[0058] It should also be noted that steps 101 to 103 above can be understood as the negotiation process in the vehicle wireless network connection method described in the embodiments of the present invention.

[0059] In one embodiment, optionally, the network sharing request carries the identifier of the first vehicle terminal and / or the identifier of at least one second vehicle terminal.

[0060] In this embodiment of the invention, the first vehicle terminal broadcasts the network sharing request via the direct link, the network sharing request carrying the identifier of the first vehicle terminal; or,

[0061] The first vehicle terminal broadcasts the network sharing request via the direct link. The network sharing request carries the identifier of the first vehicle terminal and the identifier of at least one second vehicle terminal.

[0062] Understandably, in one aspect, the network sharing request carries the identifier of the first vehicle terminal. Thus, when the second vehicle terminal receives the identifier of the first vehicle terminal in the network sharing request, it can also carry the identifier of the first vehicle terminal in its network sharing response. The second vehicle terminal broadcasts the network sharing response. Since the network sharing response carries the identifier of the first vehicle terminal, the first vehicle terminal can receive the network sharing response sent by the second vehicle terminal.

[0063] On the other hand, if the network sharing request carries the identifier of at least one second vehicle terminal, then at least one second vehicle terminal can respond to the network sharing request; if the network sharing request only carries the identifier of the first vehicle terminal, then vehicle terminals other than at least one second vehicle terminal can also respond to the network sharing request.

[0064] In one implementation, optionally, the network sharing request also carries a request identifier.

[0065] In this embodiment of the invention, the request identifier is used to indicate the network sharing request. The request identifier can be represented by reqID. The network sharing request carries the request identifier. Thus, when the second vehicle terminal receives the request identifier in the network sharing request, it can also carry the request identifier in the network sharing response. The first vehicle terminal receives the request identifier in the network sharing response to match the network sharing request.

[0066] In one implementation, optionally, the network sharing request also carries a request status identifier.

[0067] In this embodiment of the invention, the request status identifier is used to indicate the request status of the network sharing request, and the request status identifier can be represented by reqStatus. Here, the value of the request status identifier in the network sharing request sent by the first vehicle terminal is request(1).

[0068] The second vehicle terminal receives the request status identifier in the network sharing request and may also carry the request status identifier in the network sharing response. If the network sharing response is an allow sharing response, the value of the request status identifier in the network sharing response is accept (6), which is used to indicate the request status of allowing the network sharing request; if the network sharing response is a reject sharing response, the value of the request status identifier in the network sharing response is reject (7), which is used to indicate the request status of rejecting the network sharing request.

[0069] In one embodiment, optionally, the network sharing request carries the identifier of the first vehicle terminal and the identifier of at least one second vehicle terminal; the method further includes:

[0070] Receives identification information, service capability announcements, and location information from each of the multiple vehicle terminals;

[0071] Based on the service capability announcement and the location information, at least one second vehicle terminal with network sharing capability and located within a preset range of the first vehicle terminal is selected from among the multiple vehicle terminals.

[0072] In this embodiment of the invention, if the network sharing request carries the identifier of the first vehicle terminal and the identifier of at least one second vehicle terminal, then before step 101, the first vehicle terminal can receive the identifiers of multiple vehicle terminals, service capability announcements, and location information. The service capability announcements are used to indicate the capabilities possessed by the vehicle terminals, such as network sharing capabilities. The first vehicle terminal selects at least one second vehicle terminal with network sharing capabilities from among the multiple vehicle terminals and within a preset range of the first vehicle terminal, so that in step 101, the network sharing request broadcast via a direct link carries the identifier of at least one second vehicle terminal.

[0073] Here, the second vehicle terminal periodically sends its identifier, service capability announcements, and location information according to application layer instructions, typically at a frequency of 1Hz.

[0074] Therefore, this embodiment of the invention further includes selecting at least one second vehicle terminal before step 101. Here, selecting at least one second vehicle terminal is essentially a process of discovering the second vehicle terminal, referred to as the discovery process. The vehicle wireless network connection method described in this embodiment of the invention includes not only the negotiation process of steps 101 to 103 described above, but also a discovery process prior to the negotiation process.

[0075] In one implementation, optionally, the network sharing request carries the expected response time of the network sharing response;

[0076] Receiving a network sharing response sent by the second vehicle terminal in response to the network sharing request includes:

[0077] Within the expected response time, the second vehicle terminal sends a network sharing response in response to the network sharing request.

[0078] In this embodiment of the invention, the first vehicle terminal sends the network sharing request in step 101, carrying the expected response time of the network sharing response. After step 101, the first vehicle terminal starts a timer and receives the network sharing response sent by the second vehicle terminal in response to the network sharing request within the expected response time.

[0079] It should be noted that after step 101, the first vehicle terminal starts a timer, and if no network sharing response is received when the expected response time is reached, the timer stops and reports the lack of network sharing response to the application layer, which then determines the subsequent strategy, such as resending the network sharing request.

[0080] In one embodiment, optionally, the method further includes at least one of the following:

[0081] Network information is obtained through the data transmission path;

[0082] Periodically send the Basic Safety Message (BSM) to the first vehicle terminal;

[0083] The BSM of the second vehicle terminal is received periodically.

[0084] In this embodiment of the invention, after step 103, the first vehicle terminal can obtain network information through the data transmission path and the second vehicle terminal. The network information is related to the network needs of the user of the first vehicle terminal; for example, if the user of the first vehicle terminal wants to listen to music, the network information is music song information; if the user of the first vehicle terminal wants navigation, the network information is map information.

[0085] Furthermore, after step 103, the first vehicle terminal can periodically send its own BSM (Browser Message Signal). In this way, the second vehicle terminal can receive the BSM of the first vehicle terminal, determine that the first vehicle terminal is online, and continue to share the wireless network for the first vehicle terminal.

[0086] Furthermore, after step 103, the first vehicle terminal can also periodically receive the BSM of the second vehicle terminal. In this way, the first vehicle terminal can receive the BSM of the second vehicle terminal to determine that the second vehicle terminal is online and continue to access the wireless network through the second vehicle terminal.

[0087] It should be noted that the first vehicle terminal obtaining network information through the data transmission path and the second vehicle terminal is essentially a process in which the first vehicle terminal and the second vehicle terminal enter a hotspot sharing process, referred to as the sharing process. The vehicle wireless network connection method described in this embodiment of the invention includes not only the negotiation process of steps 101 to 103 described above, but also the sharing process following the negotiation process.

[0088] In one embodiment, optionally, the network sharing request carries a request identifier; the method further includes:

[0089] Send and / or receive a sharing cancellation request, the sharing cancellation request being used to indicate the end of network sharing or the suspension of network sharing, and the sharing cancellation request carrying the request identifier;

[0090] Receive and / or send a share cancellation response, wherein the share cancellation effect carries the request identifier.

[0091] In this embodiment of the invention, after step 103, both the first vehicle terminal and the second vehicle terminal can initiate a sharing cancellation request at any time.

[0092] Both the sharing cancellation request and the sharing cancellation response carry the request identifier, and the request identifier in the sharing cancellation request and the sharing cancellation response is the same as the request identifier in the network sharing request.

[0093] Furthermore, the sharing cancellation request may also carry a request status identifier, and the value of the request status identifier is cancel(3), used to indicate the request status of canceling the network sharing request. The sharing cancellation response may also carry a request status identifier, and the value of the request status identifier is revoke(8), used to indicate the request status of canceling the network sharing request.

[0094] Furthermore, the sharing cancellation request sent by the first vehicle terminal may also carry the identifier of the second vehicle terminal, so that the second vehicle terminal receiving the identifier of the second vehicle terminal may cancel sharing the wireless network with the first vehicle terminal.

[0095] Alternatively, the sharing cancellation request received by the first vehicle terminal may also carry the identifier of the first vehicle terminal, so that the first vehicle terminal can cancel access to the wireless network through the second vehicle terminal.

[0096] Therefore, the embodiment of the present invention further includes a cancellation process after step 103. The vehicle wireless network connection method described in this embodiment of the present invention includes, in addition to the negotiation process described in steps 101 to 103 above, a cancellation process following the negotiation process.

[0097] In one implementation, optionally, if the network sharing response is a sharing permission response, the network sharing response carries the sharing validity period and / or the maximum sharing traffic;

[0098] Sending and / or receiving a share cancellation request, including:

[0099] If the shared validity period and / or the maximum shared traffic are satisfied, send and / or receive a shared cancellation request.

[0100] In this embodiment of the invention, after step 103, the first vehicle terminal and the second vehicle terminal may initiate a sharing cancellation request if the sharing validity period and / or the maximum sharing traffic are satisfied.

[0101] The sharing validity period refers to the duration during which the first vehicle terminal shares the wireless network with the second vehicle terminal, starting from the time the first vehicle terminal establishes the data transmission path with the second vehicle terminal.

[0102] The maximum shared traffic refers to the maximum allowed traffic of the first vehicle terminal through the data transmission path and the network information obtained by the second vehicle terminal.

[0103] In one implementation, optionally, the network sharing request carries information about sharing points;

[0104] In the case of sending and / or receiving a share cancellation request, the method further includes:

[0105] According to the agreed rules, the credit points of the first vehicle terminal are transferred to the second vehicle terminal.

[0106] In this embodiment of the invention, the network sharing request carries information about sharing points, which are credit points that the second vehicle terminal shares the wireless network with the first vehicle terminal, and that the first vehicle terminal can transfer to the second vehicle terminal.

[0107] Specifically, when sending and / or receiving a sharing cancellation request, during the sharing cancellation process, the first vehicle terminal may transfer its credit points to the second vehicle terminal according to the agreed rules.

[0108] In one embodiment, optionally, the network sharing request and / or the network sharing request carries sharing information of credit points; if the network sharing response is a rejection response, the network sharing response carries rejection information indicating that the credit points are insufficient, and carries suggestion information indicating that the credit points should be increased.

[0109] In this embodiment of the invention, if in step 102, the network sharing response received by the first vehicle terminal is a rejection response, and the network sharing response carries rejection information indicating insufficient credit points and suggestion information indicating an increase in credit points, then after step 102, the first vehicle terminal can adjust the sharing points information in the network sharing request according to the rejection information and the suggestion information, obtain the adjusted network sharing request, and resend the adjusted network sharing request.

[0110] Therefore, by employing the vehicle wireless network connection method described in this embodiment of the invention, a dynamic and self-organizing vehicular self-organizing network is constructed through V2V direct connection technology. This enables vehicles in signal blind spots to connect to "seed vehicles" with superior network signal quality via multi-hop relays, thereby achieving network extension and sharing. This "dandelion"-like information dissemination model no longer relies on fixed infrastructure, greatly enhancing the resilience and robustness of the entire transportation system's network connectivity, improving user experience, and eliminating network information anxiety.

[0111] See Figure 2 This invention provides a wireless network connection method for a vehicle, applied to a second vehicle terminal. For example, the second vehicle terminal is a communication device that supports cellular technology or direct communication between devices / terminal passthrough / device-to-device technology, etc. Specifically, the second vehicle terminal is a communication device that supports C-V2X technology.

[0112] Step 201: Receive network sharing requests via a direct link;

[0113] In this embodiment of the invention, the Sidelink supports C-V2X technology for device-to-device communication, allowing direct data exchange between vehicle terminals.

[0114] The network sharing request sent by the first vehicle terminal can be understood as a connection request to connect to a "vehicle hotspot." Here, a "vehicle hotspot" refers to sharing a wireless network connection with other communication devices through the vehicle terminal. The first vehicle terminal can be understood as the requester of the "vehicle hotspot," and the second vehicle terminal can be understood as the sharer of the "vehicle hotspot."

[0115] Step 202: In response to the network sharing request, send a network sharing response;

[0116] In this embodiment of the invention, the network sharing response includes an allow sharing response or a deny sharing response.

[0117] Step 203: If the network sharing response is an enable sharing response, a data transmission path is established with the first vehicle terminal, and the first vehicle terminal accesses the wireless network through the data transmission path.

[0118] In this embodiment of the invention, when the network sharing response is an enable sharing response, it means that the first vehicle terminal and the second vehicle terminal have successfully established a data transmission path. Through the data transmission path, the second vehicle terminal can share the wireless network with the first vehicle terminal.

[0119] It should be noted that the second vehicle terminal can perform the steps executed by the second vehicle terminal in the above-described wireless network connection method for the vehicle applied to the first vehicle terminal, which will not be repeated here.

[0120] In one embodiment, optionally, the network sharing request carries the identifier of the first vehicle terminal and / or the identifier of at least one second vehicle terminal.

[0121] In one embodiment, optionally, the network sharing request carries the identifier of the first vehicle terminal and / or at least one identifier of the second vehicle terminal; the method further includes:

[0122] Send the identifier, service capability announcement, and location information of the second vehicle terminal.

[0123] In one implementation, optionally, the network sharing request carries the expected response time of the network sharing response;

[0124] In response to the network sharing request, a network sharing response is sent, including:

[0125] Within the expected response time, in response to the network sharing request, a network sharing response is sent.

[0126] In one embodiment, optionally, the method further includes at least one of the following:

[0127] Periodically receive basic security messages from the first vehicle terminal;

[0128] The second vehicle terminal periodically sends basic security messages.

[0129] In one embodiment, optionally, the network sharing request carries a request identifier; the method further includes:

[0130] Receive and / or send a sharing cancellation request, the sharing cancellation request being used to indicate the end of network sharing or the suspension of network sharing, and the sharing cancellation request carrying the request identifier.

[0131] In one implementation, optionally, if the network sharing response is a sharing permission response, the network sharing response carries the sharing validity period and / or the maximum sharing traffic;

[0132] Receive and / or send a share cancellation request, including:

[0133] If the shared validity period and / or the maximum shared traffic are satisfied, receive and / or send a shared cancellation request.

[0134] In one implementation, optionally, the network sharing request carries information about sharing points;

[0135] In the case of receiving and / or sending a share cancellation request, the method further includes:

[0136] Obtain the credit points transferred by the first vehicle terminal according to the agreed rules.

[0137] In one embodiment, optionally, the network sharing request carries sharing information of credit points; if the network sharing response is a rejection response, the network sharing response carries rejection information indicating that the credit points are insufficient, and suggestion information indicating that the credit points should be increased.

[0138] Figure 3 This is a flowchart illustrating one embodiment of the wireless network connection method for vehicles described in this invention. Figure 3 As shown, the method includes:

[0139] Discovery process:

[0140] Step 301: The second vehicle terminal sends a service capability announcement;

[0141] Negotiation process:

[0142] Step 302: The first vehicle terminal selects the second vehicle terminal according to the service capability announcement and sends a network sharing request;

[0143] Step 303: The second vehicle terminal sends a network sharing response;

[0144] Step 304: If the network sharing response is an allow sharing response, then the first vehicle terminal sends a sharing start message;

[0145] Sharing process:

[0146] The first vehicle terminal obtains network information through the second vehicle terminal;

[0147] Step 305: The first vehicle terminal sends a sharing completion message;

[0148] Cancellation process:

[0149] Step 306: The second vehicle terminal sends a sharing cancellation request;

[0150] Alternatively, in step 307, the first vehicle terminal sends a sharing cancellation request;

[0151] Step 308: The credit points of the first vehicle terminal are transferred to the second vehicle terminal, and the second vehicle terminal obtains the credit points transferred by the first vehicle terminal.

[0152] In summary, the wireless network connection method for vehicles described in this invention enables the first vehicle terminal to interact with surrounding second vehicle terminals using V2V vehicle direct communication technology. By sharing hotspots with these second vehicle terminals, network collaboration is achieved. This transforms connected vehicles from isolated "information islands" into a "smart continent," shifting from passive prevention to proactive response, improving network resilience, and enabling resource sharing with zero marginal cost. This invention also provides a complete signaling process for discovery, negotiation, execution, and cancellation, and outlines a credit score transfer mechanism and delivery process, demonstrating commercial potential.

[0154] The first sending module 401 is used to broadcast a network sharing request via a direct link;
