[0050] To make the objectives, technical solutions and advantages of the present invention more clear, the following will clearly and completely describe the technical solutions of the present invention in combination with specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part rather than all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0051] In the description of one or more embodiments of the present invention, the term "including" and its similar terms should be understood as open inclusion, that is, "including but not limited to". The term "based on" should be understood as "at least partially based on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". Terms such as "first", "second", etc. may refer to different or the same objects. There may also be other explicit and implicit definitions below.

[0052] With the continuous development of technology, more and more vehicle models are starting to be equipped with wireless access points to provide in-vehicle networks. On the one hand, it can meet the interconnection and communication needs and networking needs among the driving recorders, reverse cameras, co-pilot screens, rear seat screens, etc. installed in the vehicle, and can also reduce the wiring harnesses required to be laid in the vehicle, with good flexibility. On the other hand, it can also enable the driver and passengers to easily access streaming media services by connecting mobile terminal devices to the in-vehicle network and enjoy multimedia content such as music, videos, and games, so as to enhance the driving and riding experience of the driver and passengers.

[0053] However, although the in-vehicle network provided by the wireless access points installed in the vehicle can bring convenience to the driver and passengers, there are still certain challenges in the safety management during the operation of the vehicle network. For example, currently, usually only a single wireless access point is provided in the vehicle, so that all the intelligent devices in the vehicle and the mobile terminal devices of the driver and passengers will be connected to the same in-vehicle network, thus making it impossible to effectively manage the communication situations among the devices connected to the in-vehicle network. In addition, since the in-vehicle network usually supports Internet access, illegal persons may remotely access the devices connected to the in-vehicle network by taking advantage of security vulnerabilities, which is also likely to cause a risk of leakage of sensitive data in these devices.

[0054] Based on this, how to ensure the security and controllability during the operation of the in-vehicle network has become a technical problem that urgently needs to be solved.

[0055] The present invention provides a method for connecting a wireless access point. This method enables a vehicle to provide multiple wireless access points with different supported data transmission types. When a connection request for a target wireless access point provided by the vehicle from a target station is received, information carried in the connection request that reflects the data transmission requirements of the target station can be combined. When it is determined that the data transmission type supported by the target wireless access point can meet the data transmission requirements of the target station, a wireless connection between the target wireless access point and the target station is established. Thus, on the basis of meeting the different Internet usage requirements of the passengers in the vehicle, the security and controllability of the in-vehicle network operation can be improved.

[0056] Please refer to Figure 1 , which is a schematic flowchart of a method for connecting a wireless access point provided by an embodiment of the present invention. From a program perspective, the execution subject of this process can be the program of the target wireless access point installed in the vehicle. Alternatively, the execution subject of this process can also be the target wireless access point in the vehicle, and no specific limitation is made in this regard.

[0057] Among them, the vehicle usually can provide multiple wireless access points, and at least some of the supported data transmission types of the wireless access points can be different; and the above-mentioned target wireless access point can be any wireless access point provided by the vehicle, and no specific limitation is made in this regard.

[0058] Next, for Figure 1 the process shown below, the method for connecting the wireless access point specifically may include the following steps:

[0059] Step S102, obtain a connection request for the target wireless access point from the target station; among them, information carried in the connection request that reflects the data transmission requirements of the target station is included.

[0060] In an embodiment of the present invention, a target wireless access point (Access Point, AP) can be commonly known as a "Wi-Fi hotspot". It can serve as the central node of the network, responsible for managing the access and data forwarding of the target station (Station, STA), so that the target station can connect to the in-vehicle network through the Wi-Fi method to perform local area network communication or access the Internet through the in-vehicle network.

[0061] In practical applications, a vehicle may be equipped with a Wi-Fi module, so that the Wi-Fi module can be used to provide multiple wireless access points including the target wireless access point. It can be understood that the relationship between the Wi-Fi module and the wireless access point can be either a one-to-one relationship or a one-to-many relationship, and no specific limitation is imposed thereon. Moreover, there can be various types of the target sites. For example, it may include a driving recorder, a reverse camera, a co-pilot screen, a rear seat screen, a laptop computer, a smart phone, a smart bracelet, etc., and no specific limitation is imposed thereon either.

[0062] In an embodiment of the present invention, when the target site has a data transmission requirement and the target site expects to use the in-vehicle network corresponding to the target wireless access point for data transmission, the target site may generate a connection request carrying information for reflecting the data transmission requirement of the target site and send the connection request to the target wireless access point, so that the target wireless access point can decide whether to establish a wireless connection therebetween.

[0063] Step S104, determine whether the data transmission type supported by the target wireless access point can meet the data transmission requirement of the target site, and obtain a first determination result.

[0064] In an embodiment of the present invention, the data transmission types supported by each wireless access point at the vehicle can be preset, and the data transmission types supported by different wireless access points may be different. Moreover, the data transmission requirements that can be met by different data transmission types may also be different. Based on this, in order to reduce the inconvenience caused by the need to replace the connected wireless access point because the successfully connected wireless access point cannot meet the data transmission requirement of the target site, after receiving the connection request from the target site, the target wireless access point can detect whether the data transmission type supported by the target wireless access point itself can meet the data transmission requirement of the target site, so as to decide whether to establish a wireless connection therebetween in combination with the corresponding determination result.

[0065] In practical applications, the data transmission requirement of the target site can be determined according to the type, function of the target site and the requirements of the current user. For example, when the target site is a driving recorder, its data transmission requirement can be either to send the captured image data or video data to the in-vehicle main screen for display or to send the captured image data or video data to the cloud server for storage. When the target site is a smart phone of a driver or passenger, its data transmission requirement can be either to project the video played on the smart phone to the rear seat screen at the vehicle or to access Internet data, etc., and no specific limitation is imposed thereon.

[0066] In practical applications, the data transmission types supported by the target wireless access point may include at least one of: Internet data transmission type, mobile device screen mirroring data transmission type, and vehicle area network data transmission type. Among them, the Internet data transmission type may indicate that after the target site successfully accesses the target wireless access point, it can access and receive Internet data based on the vehicle network corresponding to the target wireless access point. The mobile device screen mirroring data transmission type may indicate that after the target site successfully accesses the target wireless access point, it can mirror the data at the target site to other devices connected to the target wireless access point for display. The vehicle area network data transmission type may indicate that after the target site successfully accesses the target wireless access point, it can perform data interaction with other devices connected to the target wireless access point, but cannot access the Internet. Of course, according to actual needs, the data transmission types supported by the target wireless access point may also include other types, which are not specifically limited herein.

[0067] In practical applications, the vehicle networks corresponding to the respective wireless access points on the vehicle can usually be data-isolated from each other. Therefore, the multiple vehicle networks on the vehicle can belong to independent virtual local area networks, so that by pre-setting the data transmission types supported by the wireless access points corresponding to the respective vehicle networks, it is possible to conveniently implement effective control over the data transmission processes of the respective sites connected to the vehicle network.

[0068] Moreover, since when a wireless access point only supports the vehicle area network data transmission type, the sites connected to the wireless access point cannot be accessed by the Internet, it is beneficial to ensure the security of sensitive data at the site. When a wireless access point only supports the mobile device screen mirroring data transmission type, the data transmission functions that the sites connected to the wireless access point can utilize the vehicle network to implement will be limited to the screen mirroring function, which is also beneficial to improving the controllability of data transmission during the operation of the vehicle network. When a wireless access point only supports the Internet data transmission type, it can fully meet the various networking needs of users. Based on this, it can be seen that when the data transmission types supported by different wireless access points are different, the data security levels of the vehicle networks corresponding to different wireless access points can be different, so that it is possible to implement hierarchical control over the security risks existing during the operation of the vehicle network, with good flexibility.

[0069] To facilitate understanding of the vehicle network situation provided by the vehicle, an example is given herein in conjunction with Figure 2 for illustration. Figure 2 FIG. is a schematic diagram of a connection scenario of a wireless access point provided by an embodiment of the present invention. As shown in Figure 2As shown, it is assumed that the in-vehicle device at the vehicle can provide a first wireless access point 201, a second wireless access point 202, and a third wireless access point 203. The first wireless access point 201 only supports the Internet data transmission type, the second wireless access point 202 only supports the mobile device screen mirroring data transmission type, and the third wireless access point 203 only supports the in-vehicle local area network data transmission type.

[0070] Based on this, when the main screen device 204, the co-pilot screen device 205, the left rear row screen device 207, and the right rear row screen device 208 are all wired to the in-vehicle device, if a passenger needs to use the smartphone 206 to perform screen mirroring at any of the above in-vehicle screen devices, the passenger can operate the smartphone 206 to connect to the second wireless access point 202. Alternatively, when the left rear row screen device 207 and the right rear row screen device 208 are both in-vehicle tablet devices, the passenger can also connect the left rear row screen device 207 and the right rear row screen device 208 to the second wireless access point 202, so that the smartphone 206 can perform screen mirroring to them after connecting to the second wireless access point 202, which has good flexibility.

[0071] Alternatively, when a passenger wants to use in-vehicle tablet devices such as the left rear row screen 207 and the right rear row screen device 208 or the smartphone 206 to browse the Internet, the above devices can be operated to establish a wireless connection with the first wireless access point 201. Alternatively, when the application at the host device allows the video data collected by the dashcam 209 to be displayed at the right rear row screen device 208, the dashcam 209 and the right rear row screen device 208 can be both wirelessly connected to the third wireless access point 203 to meet the actual needs. It can be understood that when the data transmission requirements of the above devices change, the wireless access point they need to connect to can also be changed according to the actual needs, which will not be elaborated here.

[0072] Step S106, if the first judgment result indicates that the data transmission type supported by the target wireless access point can meet the data transmission requirements of the target site, establish a wireless connection between the target wireless access point and the target site.

[0073] In the embodiment of the present invention, if the first judgment result indicates that the data transmission type supported by the target wireless access point can meet the data transmission requirements of the target site, the target wireless access point can usually allow the establishment of a wireless connection between the two, so that the target site can successfully access the in-vehicle network corresponding to the target wireless access point, and then the in-vehicle network can be used to perform relevant data transmission to meet its own data transmission requirements, which is convenient and fast.

[0074] When the first judgment result indicates that the data transmission type supported by the target wireless access point cannot meet the data transmission requirements of the target site, the target wireless access point usually rejects establishing a wireless connection between the two. Subsequently, the target site can try to establish a wireless connection with other wireless access points provided by the vehicle, which will not be elaborated here.

[0075] Figure 1 The method in can enable the vehicle to provide multiple wireless access points with different supported data transmission types. When receiving a connection request from the target site for the target wireless access point provided by the vehicle, it is possible to combine the information carried in the connection request that reflects the data transmission requirements of the target site. When it is determined that the data transmission type supported by the target wireless access point can meet the data transmission requirements of the target site, a wireless connection between the target wireless access point and the target site is established. Thus, on the basis of meeting the different Internet usage requirements of the passengers in the vehicle, the security and controllability of the in-vehicle network operation can be improved.

[0076] In a feasible implementation manner, before obtaining the connection request from the target site for the target wireless access point, it may further include:

[0077] Sending the access point information of the target wireless access point to the target site; wherein, the access point information carries preset identification information of the data transmission type supported by the target wireless access point.

[0078] Correspondingly, obtaining the connection request from the target site for the target wireless access point may include:

[0079] Obtaining a connection request carrying target identification information of a data transmission type that matches the data transmission requirements of the target site.

[0080] Correspondingly, determining whether the data transmission type supported by the target wireless access point can meet the data transmission requirements of the target site may include:

[0081] Determining whether the target identification information of the data transmission type carried in the connection request is consistent with the preset identification information of the data transmission type supported by the target wireless access point.

[0082] In the embodiments of the present invention, unique preset identification information can be set in advance for each data transmission type supported by the wireless access points in the vehicle. And since the data transmission type supported by the wireless access point can reflect the data transmission requirements it can meet, based on this, the target wireless access point can send the access point information carrying the preset identification information of the data transmission type it supports to the target site.

[0083] After determining that the target wireless access point can meet the data transmission requirements of the target site by combining the preset identification information of the data transmission type supported by the target wireless access point, the target site can generate a connection request carrying the target identification information of the data transmission type matching its own data transmission requirements, and use the target identification information of the data transmission type carried in the connection request as the information reflecting its data transmission requirements.

[0084] Subsequently, if the target wireless access point determines that the target identification information of the data transmission type carried in the connection request of the target site is consistent with the preset identification information of the data transmission type supported by itself, it can be considered that itself can meet the data transmission requirements of the target site, and then it can allow the establishment of a wireless connection between the two. If the target wireless access point determines that the target identification information of the data transmission type carried in the connection request of the target site is inconsistent with the preset identification information of the data transmission type supported by itself, it can be considered that itself cannot meet the data transmission requirements of the target site, and then it can refuse to establish a wireless connection between the two, which is convenient and fast.

[0085] In a feasible implementation manner, sending the access point information of the target wireless access point to the target site may include:

[0086] If the target wireless access point is a wireless access point with a data security level lower than the preset data security level, sending a beacon frame carrying the preset identification information of the data transmission type supported by the target wireless access point to the target site; and / or,

[0087] Sending a probe response frame carrying the preset identification information of the data transmission type supported by the target wireless access point to the target site.

[0088] In the embodiments of the present invention, a beacon frame (Beacon) is usually periodically sent by a wireless access point AP at a certain time interval to announce the existence of the wireless network corresponding to the wireless access point. In practical applications, the beacon frame usually contains network parameters of the wireless network, such as service set identifier (Service Set Identifier, SSID) information, the data rate it supports, and related security settings, etc., which are not specifically limited herein.

[0089] In an embodiment of the present invention, after a station obtains the network parameters of a wireless access point through a beacon frame, it may send a probe request frame carrying the SSID information and supported rate information of the wireless access point to the wireless access point to indicate the network it desires to join and its own capabilities. The wireless access point will then reply with a probe response frame carrying its own SSID information, MAC address, encryption method, etc. to the station, so that the station can initiate a connection request to the wireless access point in the next authentication stage.

[0090] In an embodiment of the present invention, according to the data transmission types supported by each wireless access point, the data security levels of each wireless access point can be preset. Alternatively, the data security levels corresponding to each data transmission type can be preset, and the data security level corresponding to the data transmission type supported by the wireless access point can be used as the data security level of the wireless access point, without specific limitation. And in practical applications, the data security levels corresponding to the Internet data transmission type, the mobile device screen mirroring data transmission type, and the in-vehicle local area network data transmission type can increase in sequence, or the data security levels of the wireless access points supporting the above respective data transmission types can increase in sequence. Of course, different data security levels can also be set for the above data transmission types according to actual needs, without specific limitation.

[0091] In an embodiment of the present invention, when the data security level of a wireless access point is relatively low, generally, the control over the access process of the wireless access point can be appropriately relaxed. Therefore, a wireless access point with a data security level lower than the preset data security level is allowed to send a beacon frame and a probe response frame carrying the SSID information of the wireless access point to the station.

[0092] Moreover, since the station can obtain the beacon frame and the probe response frame sent by the wireless access point before generating a connection request for the wireless access point, and the preset identification information of the data transmission type supported by the wireless access point can also be regarded as a kind of network parameter of the vehicle-mounted network. Based on this, the preset identification information of the data transmission type supported by the target wireless access point can be added to the beacon frame and the probe response frame that the target wireless access point needs to send, so that the target station can obtain the preset identification information of the data transmission type supported by the target wireless access point by receiving the beacon frame and / or the probe response frame sent by the target wireless access point, which is convenient and fast.

[0093] In practical applications, both the beacon frame and the probe response frame can include an SSID Element field. The SSID Element field usually contains information such as Element ID, Length, and SSID. Based on this, preset identification information of the data transmission type supported by the target wireless access point can also be added to the SSID Element field, so that the beacon frame and the probe response frame can carry the preset identification information of the data transmission type supported by the target wireless access point. Of course, other fields in the beacon frame and the probe response frame can also be used to carry the preset identification information of the data transmission type supported by the target wireless access point, and no specific limitation is made in this regard.

[0094] In a feasible implementation manner, sending the access point information of the target wireless access point to the target station may include:

[0095] If the target wireless access point is a wireless access point whose data security level is equal to or higher than the preset data security level, after the target wireless access point receives a probe request frame carrying the service set identifier of the target wireless access point sent by the target station, it sends a probe response frame carrying the preset identification information of the data transmission type supported by the target wireless access point to the target station.

[0096] Wherein, the target wireless access point is a wireless access point that is prohibited from sending a beacon frame carrying the service set identifier of the target wireless access point in the probe request frame.

[0097] In the embodiment of the present invention, when the data security level of the wireless access point is relatively high, it is usually necessary to strictly control the access process of this wireless access point to reduce the risks that may be brought by the site randomly connecting to this wireless access point. Therefore, a wireless access point whose data security level is equal to or higher than the preset data security level can be prohibited from sending a beacon frame (Beacon) carrying the SSID information of this wireless access point to the site. At this time, only a site that has pre-stored the SSID information of this wireless access point, or a site that can receive the SSID information of this wireless access point input by the user, can send a probe request frame carrying the SSID information of this wireless access point to this wireless access point. Subsequently, this wireless access point can send a probe response frame carrying the preset identification information of the data transmission type supported by this wireless access point to this site, so that this site can obtain the preset identification information of the data transmission type supported by this wireless access point.

[0098] Based on this, if the target wireless access point is a wireless access point with a data security level equal to or higher than the preset data security level, the target wireless access point needs to send a probe response frame carrying preset identification information of the data transmission type it supports to the target site only after receiving a probe request frame carrying the service set identifier of the target wireless access point sent by the target site. For a site that cannot obtain the service set identifier of the target wireless access point, since such a site cannot send a probe request frame carrying the service set identifier of the target wireless access point to the target wireless access point, the target wireless access point will not send a probe response frame to such a site. Therefore, such a site usually cannot know the preset identification information of the data transmission type supported by the target wireless access point, and thus cannot successfully connect to the target wireless access point. This helps to improve the controllability and security of the connection process for the target wireless access point with a higher data security level.

[0099] In a feasible implementation manner, the connection request for obtaining the target identification information of the data transmission type that matches the data transmission requirement of the target site may include:

[0100] Obtaining an authentication request frame carrying the target identification information sent by the target site.

[0101] In an embodiment of the present invention, after receiving the probe response frame fed back by the target wireless access point, the target site may decide whether to join the vehicle-mounted network corresponding to the target wireless access point according to its own capabilities and the capabilities of the target wireless access point; if it decides to join, it may generate and send an authentication request frame (Authentication Request) to the target wireless access point, so that after the target wireless access point authenticates the target site in response to the authentication request frame and passes the authentication, a wireless connection is established between the two.

[0102] Based on this, the target wireless access point may use the authentication request frame received from the target site as the connection request of the target site for the target wireless access point. In practical applications, the target identification information of the data transmission type that matches the data transmission requirement of the target site may be added to an existing field in the authentication request frame, or a new field may be added to the authentication request frame to record the target identification information of the data transmission type that matches the data transmission requirement of the target site, and no specific limitation is made thereto.

[0103] In a feasible implementation manner, after determining whether the target identification information of the data transmission type carried in the connection request is consistent with the preset identification information of the data transmission type supported by the target wireless access point, it may further include:

[0104] If the target identification information is consistent with the preset identification information, send a first authentication response frame indicating successful authentication of the target site to the target site.

[0105] If the target identification information is inconsistent with the preset identification information, send a second authentication response frame indicating failed authentication of the target site to the target site.

[0106] In the embodiment of the present invention, after the target wireless access point performs identity authentication processing on the authentication request frame (Authentication Request) of the target site in response to it, it can usually return an authentication response frame (Authentication Response) to the target site to indicate whether the identity authentication of the target site is successful.

[0107] Based on this, in addition to performing identity authentication processing on the target site according to the existing identity authentication strategy, the target wireless access point can also verify whether the target identification information of the data transmission type carried in the authentication request frame of the target site is consistent with the preset identification information of the data transmission type supported by the target wireless access point. If they are consistent, it is allowed to generate and feedback a first authentication response frame indicating successful authentication of the target site to the target site; if they are inconsistent, a second authentication response frame indicating failed authentication of the target site can be generated and feedback to the target site. Thus, it can be ensured that a wireless connection between the two is established only when the target wireless access point can meet the data transmission requirements of the target site, which is convenient and fast.

[0108] In the embodiment of the present invention, according to the different device types, device sources, and data transmission requirements of different sites, each site can also have a corresponding security level. For example, the security level of in-vehicle intelligent devices can be relatively high, while the security level of mobile terminal devices carried by users can be relatively low; or, the security level of dash cams can be relatively high, while the security level of in-vehicle tablets that need to be connected to the network can be relatively low; there is no specific limitation on this. In practical applications, the corresponding security levels of each site can either be set by the user using the application program installed at the site, or can be set by itself according to the data transmission requirements of the application at the site or the service functions supported by the application, etc., and there is no specific limitation on this.

[0109] To further ensure the security and controllability when the target site communicates using the vehicle-mounted network, the security level information of the target site can also be carried in the connection request of the target site for the target wireless access point (e.g., authentication response frame), so that the target wireless access point can know the security level of the target site. Subsequently, when the target site requests to connect to the target wireless access point, the target wireless access point can send the first authentication response frame indicating successful authentication for the target site to the target site when it determines that the data transmission type supported by the target wireless access point can meet the data transmission requirements of the target site, and the security level of the target site is equal to or higher than the security level of the devices allowed to access by the target wireless access point. Otherwise, it can send the second authentication response frame indicating failed authentication for the target site to the target site. This can prevent a target site with a lower security level from using the vehicle-mounted network corresponding to a wireless access point with a higher requirement for device security level, thereby enhancing the security and controllability during the operation of the vehicle-mounted network.

[0110] It should be noted that if the security level information of the target site is not carried in the connection request, it can be considered that the target site is at the lowest security level. At this time, the target site can still successfully access the wireless access point with the lowest requirement for device security level, which is beneficial to expanding the applicable range of the wireless access point access method proposed by the present invention, reducing the transformation cost for the target site, and having good practicability.

[0111] In practical applications, the security level information of the target site and the target identification information of the data transmission type carried in the connection request and matching the data transmission requirements of the target site can be different information. Of course, since the target identification information of the data transmission type carried in the connection request can also reflect to a certain extent the possible risk level in the data transmission process of the target site, the target identification information of the data transmission type carried in the connection request can also be directly used as the security level information of the target site, and the data security level of the target wireless connection point can be used as the lowest security level of the devices allowed to access by the target wireless access point to simplify the identity authentication process. There is no specific limitation on this.

[0112] Please refer to Figure 3 , which is a schematic flowchart of a method for connecting a wireless access point provided by an embodiment of the present invention. From a program perspective, the execution subject of this process can be a program installed at the target site. Or, the execution subject of this process can also be the target site. There is no specific limitation on this.

[0113] Next, for Figure 3 the process shown, the method for connecting the wireless access point can specifically include the following steps:

[0114] Step S302: Obtain the access point information of the target wireless access point among multiple wireless access points provided by the vehicle; wherein, the access point information carries preset identification information of the data transmission type supported by the target wireless access point, and at least some of the wireless access points provided by the vehicle have different supported data transmission types.

[0115] In an embodiment of the present invention, when a target station needs to access a target wireless access point, it is usually necessary to obtain the access point information of the target wireless access point, so as to generate a connection request for the target wireless access point in combination with the access point information of the target wireless access point.

[0116] In an embodiment of the present invention, since the vehicle can provide multiple wireless access points with different supported data transmission types, and each data transmission type can be set with corresponding unique identification information, in order to facilitate the target station to identify whether each wireless access point at the vehicle can meet the data transmission requirements of the target station, the access point information obtained by the target station can include the preset identification information of the data transmission type supported by the target wireless access point.

[0117] Optionally, the data transmission type supported by the target wireless access point may include at least one or any one of an Internet data transmission type, a mobile device screen mirroring data transmission type, and a vehicle area network data transmission type, and no specific limitation is made thereto.

[0118] Step S304: Generate a connection request for the target wireless access point based on the access point information; wherein, the connection request carries information for reflecting the data transmission requirements of the target station.

[0119] In an embodiment of the present invention, after the target station determines that the target wireless access point can meet the data transmission requirements of the target station by combining the preset identification information of the data transmission type supported by the target wireless access point obtained in step S302, it can generate a connection request carrying information for reflecting the data transmission requirements of the target station, so that after the target wireless access point determines that it can meet the data transmission requirements of the target station, a wireless connection between the two can be established.

[0120] Step S306: Send the connection request to the target wireless access point, so as to establish a wireless connection between the target wireless access point and the target station when the data transmission type supported by the target wireless access point can meet the data transmission requirements of the target station.

[0121] In an embodiment of the present invention, the connection request sent by the target station to the target wireless access point when executing step S306 can be for the target wireless access point to execute Figure 1The connection request obtained in step S102 of the method, so as to jointly execute Figure 1 and Figure 3 In the method of, a wireless access between the two can be established when the target wireless access point can meet the data transmission requirements of the target site.

[0122] Figure 3 In the method of, by making the target site generate a connection request carrying information reflecting the data transmission requirements of the target site and sending the connection request to the target wireless access point, the target wireless access point can establish a wireless connection between the two when it determines that the data transmission type it supports can meet the data transmission requirements of the target site, so as to improve the security and controllability of the in-vehicle network operation on the basis of meeting the different Internet usage requirements of the occupants in the vehicle.

[0123] In a feasible implementation manner, obtaining the access point information of the target wireless access point among the multiple wireless access points provided by the vehicle may include:

[0124] Obtaining a beacon frame or a probe response frame sent by the target wireless access point and carrying preset identification information of the data transmission type supported by the target wireless access point; wherein, the target wireless access point is a wireless access point with a data security level lower than a preset data security level; or,

[0125] Generating a probe request frame carrying the service set identifier of the target wireless access point based on the service set identifier of the target wireless access point input by the user or stored locally; wherein, the target wireless access point is a wireless access point with a data security level equal to or higher than the preset data security level, and the target wireless access point is prohibited from sending a beacon frame carrying the service set identifier of the target wireless access point.

[0126] After sending the probe request frame to the target wireless access point, receiving a probe response frame sent back by the target wireless access point and carrying preset identification information of the data transmission type supported by the target wireless access point.

[0127] In the embodiment of the present invention, a target wireless access point with a data security level lower than the preset data security level can actively send a beacon frame to the target site, so that the target site can obtain the service set identifier SSID of the target wireless access point and the preset identification information of the data transmission type supported by the target wireless access point by receiving the beacon frame. Therefore, the target site can obtain the access point information of the target wireless access point by receiving the beacon frame sent by the target wireless access point.

[0128] Subsequently, the target station can also generate and send a probe request frame for the target wireless access point in combination with the service set identifier (SSID) of the target wireless access point carried in the beacon frame, and receive a probe response frame fed back by the target wireless access point. At this time, the probe response frame can also carry preset identification information of the data transmission types supported by the target wireless access point. Of course, the probe response frame may not carry the preset identification information of the data transmission types supported by the target wireless access point, and no specific limitation is made in this regard.

[0129] In the embodiment of the present invention, since the target wireless access point with a data security level equal to or higher than the preset data security level can be prohibited from sending a beacon frame to the target station, the target station cannot obtain the service set identifier (SSID) of the target wireless access point and the preset identification information of the data transmission types supported by it through the beacon frame.

[0130] Based on this, after the target station obtains the service set identifier of the target wireless access point input by the user, or obtains the service set identifier of the target wireless access point stored locally in the target station, it can generate and send a probe request frame carrying the service set identifier of the target wireless access point to the target wireless access point, so that the target wireless access point feeds back a probe response frame carrying the preset identification information of the data transmission types supported by it to the target station. At this time, the target station can obtain the access point information of the target wireless access point by receiving the probe response frame sent by the target wireless access point.

[0131] In practical applications, the service set identifier of the target wireless access point stored locally in the target station can be either information pre-stored by the user in the target station, or information obtained and stored by the target station when establishing a wireless connection with the target wireless access point last time, and no specific limitation is made in this regard. Of course, the target station can also obtain the service set identifier (SSID) of the target wireless access point with a data security level equal to or higher than the preset data security level through other means, and no specific limitation is made in this regard.

[0132] In a feasible implementation manner, generating a connection request for the target wireless access point based on the access point information may include:

[0133] Generating an authentication request frame carrying target identification information of a data transmission type matching the data transmission requirements of the target station based on the access point information.

[0134] Correspondingly, after sending the connection request to the target wireless access point, it may further include:

[0135] Receiving a first authentication response frame fed back by the target wireless access point to indicate successful authentication for the target station; wherein the first authentication response frame is an authentication response frame generated by the target wireless access point when determining that the target identification information is consistent with the preset identification information. Or,

[0136] Receiving a second authentication response frame fed back by the target wireless access point to indicate failed authentication for the target station; wherein the second authentication response frame is an authentication response frame generated by the target wireless access point when determining that the target identification information is inconsistent with the preset identification information.

[0137] In an embodiment of the present invention, since there can often be a correlation between the data transmission types supported by each wireless access point at the vehicle and the data transmission requirements of the target station, based on this, the target station can carry, in the connection request, the target identification information that is unique to the data transmission type with the highest correlation with its data transmission requirements as the information reflecting its data transmission requirements. Subsequently, when the target wireless access point determines that the target identification information carried in the connection request is consistent with the preset identification information of the data transmission type it supports, it can generate and feed back a first authentication response frame indicating successful authentication for the target station to the target station; otherwise, it can generate and feed back a second authentication response frame indicating failed authentication for the target station to the target station, so as to effectively manage the target stations accessed at the in-vehicle network.

[0138] In an embodiment of the present invention, according to the different types of devices, device sources, and data transmission requirements corresponding to different stations, each station can also have a corresponding security level. In practical applications, the corresponding security level of each station can be set by the user using the application program installed at the station, or, alternatively, it can be set by itself according to the data transmission requirements of the application at the station or the service functions supported by the application, etc., and no specific limitation is made thereto.

[0139] To further ensure the security and controllability when a site communicates using a vehicle-mounted network, the security level information of the target site can also be carried in the connection request of the target site to the target wireless access point (e.g., an authentication response frame), so that the target wireless access point can know the security level of the target site. Subsequently, when the target site requests to connect to the target wireless access point, the target wireless access point can send a first authentication response frame indicating successful authentication for the target site to the target site when it determines that the data transmission type supported by the target wireless access point can meet the data transmission requirements of the target site, and the security level of the target site is equal to or higher than the security level of the devices allowed to access by the target wireless access point. Otherwise, it can send a second authentication response frame indicating failed authentication for the target site to the target site. This can prevent a target site with a lower security level from using the vehicle-mounted network corresponding to a wireless access point with a higher requirement for device security level, thereby enhancing the security and controllability during the operation of the vehicle-mounted network.

[0140] It should be noted that if the security level information of the target site is not carried in the connection request, it can be considered that the target site is at the lowest security level. At this time, the target site can still successfully access the wireless access point with the lowest requirement for device security level, which is beneficial to expanding the applicable range of the above-mentioned wireless access point access method, reducing the transformation cost for the target site, and having good practicability.

[0141] In practical applications, the security level information of the target site and the target identification information of the data transmission type that matches the data transmission requirements of the target site carried in the connection request can be different information. Of course, since the target identification information of the data transmission type carried in the connection request can also reflect to a certain extent the possible risk level in the data transmission process of the target site, the target identification information of the data transmission type carried in the connection request can also be directly used as the security level information of the target site, and the data security level of the target wireless connection point can be used as the lowest security level of the devices allowed to access by the target wireless access point to simplify the identity authentication process. There is no specific limitation on this.
