Description

Technical Field

[0001] The present disclosure relates to the technical field of vehicle-mounted terminals, and in particular to a method, device, equipment and medium for controlling network traffic usage of a vehicle-mounted terminal. Background Art

[0002] Each mobile communication network belongs to a specific operator. When using the mobile communication network, the vehicle terminal signs a contract with the operator (hereinafter referred to as the home operator). After signing the contract, the vehicle terminal can access the home operator network, or can access the operator network that has a roaming agreement with the home operator.

[0003] At present, when the vehicle terminal accesses the mobile communication network and establishes service channels such as bearer and service quality flow, the network element in the mobile communication network allocates an IP address to the vehicle terminal, and the vehicle terminal uses the IP address as the source IP address to access the Internet. In the home operator network, the IP address of the vehicle terminal is allocated by the home operator network, and in the roaming operator network, the IP address of the vehicle terminal can be allocated by the home operator network or the roaming operator network.

[0004] The operating system and applications of the vehicle terminal can access specific websites through the Internet to obtain corresponding services. In actual application, the operating system and applications of the vehicle terminal may leak traffic. However, the solution for managing leaked traffic at the application level cannot avoid the leakage of underlying, non-business-related traffic. In addition, the network only counts the network traffic usage of the vehicle terminal and does not intervene in the mobile network traffic usage of the vehicle terminal. Therefore, for some special scenarios related to the vehicle terminal, it is necessary to manage the Internet services that the vehicle terminal can access from the perspective of the vehicle terminal, so as to achieve the management of mobile network traffic. In summary, there is a need for a solution that can actively control mobile network traffic based on the vehicle terminal.

[0005] According to the current IP address allocation principle, the IP address allocated by the network to the vehicle terminal is not a public IP address, but a local area network IP address with the operator network as the granularity. Therefore, it is not possible to simply use the IP address to directly control the mobile network traffic of the vehicle terminal. Summary of the invention

[0006] In order to solve the above technical problems, the present disclosure provides a method, device, equipment and medium for controlling network traffic usage of a vehicle-mounted terminal.

[0007] In a first aspect, an embodiment of the present disclosure provides a method for controlling network traffic usage of a vehicle-mounted terminal, comprising:

[0008] In response to the vehicle-mounted terminal accessing the operator network, obtaining a PLMN identifier and an IP address currently used by the vehicle-mounted terminal;

[0009] Querying the IP address range corresponding to the currently used PLMN identifier in the preset IP pool, and matching the IP address with the IP address range to determine the service status of the IP address;

[0010] In response to the vehicle terminal attempting to access a network address, performing access control according to the service status and the network address through a built-in domain name system of the vehicle terminal;

[0011] Wherein, when the service status is a restricted status and the network address is not included in the built-in domain name system, the built-in domain name system cannot resolve the network address and denies access to the network address.

[0012] In a second aspect, an embodiment of the present disclosure provides a network traffic usage control device for a vehicle-mounted terminal, comprising:

[0013] An acquisition module, configured to acquire a PLMN identifier and an IP address currently used by the vehicle-mounted terminal in response to the vehicle-mounted terminal accessing the operator network;

[0014] A determination module, configured to query a preset IP pool for an IP address range corresponding to the currently used PLMN identifier, and match the IP address with the IP address range to determine the service status of the IP address;

[0015] a control module, for performing access control according to the service status and the network address through a built-in domain name system of the vehicle terminal in response to the vehicle terminal attempting to access the network address;

[0016] Wherein, when the service status is a restricted status and the network address is not included in the built-in domain name system, the built-in domain name system cannot resolve the network address and denies access to the network address.

[0017] In a third aspect, an embodiment of the present disclosure provides an electronic device, comprising: a processor; a memory for storing executable instructions of the processor; the processor is used to read the executable instructions from the memory and execute the instructions to implement the network traffic usage control method of the vehicle-mounted terminal described in the first aspect above.

[0018] In a fourth aspect, an embodiment of the present disclosure provides a computer-readable storage medium, wherein the storage medium stores a computer program, and when the computer program is executed by a processor, the method for controlling network traffic usage of a vehicle-mounted terminal described in the first aspect above is implemented.

[0019] Compared with the prior art, the technical solution provided by the disclosed embodiment has the following advantages: in response to the vehicle-mounted terminal accessing the operator network, the PLMN identifier and IP address currently used by the vehicle-mounted terminal are obtained, and the IP address is matched with the IP address range corresponding to the PLMN identifier currently used in the preset IP pool to determine the service status of the IP address. Then, in response to the vehicle-mounted terminal attempting to access the network address, access control is performed according to the service status and the network address through the built-in domain name system of the vehicle-mounted terminal. When the service status is restricted and the network address is not included in the built-in domain name system, the built-in domain name system cannot resolve the network address and refuses access to the network address. Therefore, by configuring the preset IP pool and the built-in domain name system, the mobile network traffic is jointly controlled in combination with the IP address of the vehicle-mounted terminal and the PLMN of the current network operator, and active management of the mobile network traffic of the vehicle-mounted terminal is achieved. While controlling the mobile network traffic of the vehicle terminal, the problem of underlying, non-service-related traffic leakage is solved. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0027] First, the preset IP (Internet Protocol) pool in the embodiment of the present disclosure is described.

[0028] In the disclosed embodiment, the vehicle terminal includes a preset IP pool, which may include a PLMN identifier and its corresponding IP address range, or may be empty. The PLMN identifier in the preset IP pool is derived from the PLMN used by the home operator of the vehicle terminal's mobile network service, and / or the PLMN used by a roaming operator that has a roaming agreement with the home operator. The PLMN identifier in the preset IP pool and its corresponding IP address range may be negotiated by the vehicle manufacturer and the operator. The preset IP pool may be configured by the operator. Taking the home operator as an example, the home operator directly configures the PLMN identifier and its corresponding IP address range in the preset IP pool used by the vehicle terminal, or uses OTA (Over the air) to send the PLMN identifier and its corresponding IP address range to the preset IP pool of the vehicle terminal.

[0029] When the vehicle terminal is in a non-roaming scenario, the home operator allocates a restricted IP address range to the vehicle terminal, and the vehicle terminal sets or updates the preset IP pool according to the IP address range allocated by the home operator; the IP address range allocated by the home operator corresponds to the PLMN identifier of the home operator.

[0030] When the vehicle terminal is in the home routing scenario, the home operator allocates a restricted IP address range to the vehicle terminal, and the vehicle terminal sets or updates the preset IP pool according to the IP address range allocated by the home operator; the IP address range allocated by the home operator corresponds to the PLMN identifier of the roaming operator.

[0031] When the vehicle terminal is in a roaming routing scenario, the home operator allocates a restricted IP address range to the vehicle terminal, and the vehicle terminal sets or updates the preset IP pool according to the IP address range allocated by the home operator; the IP address range allocated by the home operator corresponds to the PLMN identifier of the roaming operator. Alternatively, when the vehicle terminal is in a roaming routing scenario, the roaming operator allocates a restricted IP address range to the vehicle terminal, and the vehicle terminal sets or updates the preset IP pool according to the IP address range allocated by the roaming operator; the IP address range allocated by the roaming operator corresponds to the PLMN identifier of the roaming operator.

[0032] Optionally, the operator can pre-allocate at least one IP address range corresponding to a PLMN identifier for a batch or batches of vehicles based on parameters such as IMSI (International Mobile Subscriber Identity), ICCID (Integratecircuit card identity), MSISDN (Mobile SubscriberInternational ISDNnumber, Integrated Service Digital Network) in the user identification module used by the vehicle terminal. If the vehicle terminal does not need to control the network traffic usage within a specific operator's network, the preset IP pool of the vehicle terminal does not include the operator's PLMN identifier and its corresponding IP address range.

[0033] Figure 1 This is a flow chart of a method for controlling network traffic usage of a vehicle-mounted terminal provided in an embodiment of the present disclosure. The method provided in an embodiment of the present disclosure can be executed by a network traffic usage control device of the vehicle-mounted terminal, which can be implemented in software and / or hardware and can be integrated on any electronic device with computing capabilities.

[0034] like Figure 1 As shown, the network traffic usage control method of the vehicle terminal provided by the embodiment of the present disclosure may include:

[0035] Step 101: in response to the vehicle-mounted terminal accessing the operator network, obtaining the PLMN identifier and IP address currently used by the vehicle-mounted terminal.

[0036] In this embodiment, each operator corresponds to at least one PLMN (Public Land Mobile Network), and different PLMNs are distinguished by PLMN identifiers. When the vehicle terminal accesses the operator network, the vehicle terminal selects a PLMN from the PLMN range supported and broadcast by the operator, and the operator network allocates an IP address to the vehicle terminal. Then, in response to the vehicle terminal accessing the operator network, the currently used PLMN identifier and IP address can be obtained.

[0037] As an example, when the vehicle terminal is in a non-roaming scenario, the operator network of the home operator is accessed according to the IP address assigned by the home operator. When the vehicle terminal is in a home routed (HR) scenario, the operator network of the roaming operator is accessed according to the IP address assigned by the home operator. When the vehicle terminal is in a roaming routed (Local Breakout, LBO) scenario, the operator network of the roaming operator is accessed according to the IP address assigned by the home operator, or, according to the IP address assigned by the roaming operator, the operator network of the roaming operator is accessed.

[0038] Optionally, after the vehicle-mounted terminal accesses the operator network to establish a wireless bearer, the IP address allocated to the vehicle-mounted terminal can be any one of a terminal-level IP address, a PDN (Packet Data Network) connection-level IP address, and a PDU (Packet Data Unit) session-level IP address.

[0039] Step 102, querying the preset IP pool for an IP address range corresponding to the currently used PLMN identifier, and matching the IP address with the IP address range to determine the service status of the IP address.

[0040] Among them, the vehicle-mounted terminal includes a preset IP pool. If the preset IP pool includes an IP address range corresponding to at least one PLMN identifier, wherein each PLMN identifier in the preset IP pool corresponds to one or more IP address ranges, and the IP address range corresponds to one or more IP addresses. For example, the preset IP pool is located in the subscriber identification module (Subscriber Identity Module, SIM) used by the vehicle-mounted terminal, and the IP address range is divided according to the granularity of the operator's PLMN.

[0041] In this embodiment, a query is made as to whether the preset IP pool includes an IP address range corresponding to the currently used PLMN identifier. If an IP address range corresponding to the currently used PLMN identifier is found, a match is performed between the IP address and the IP address range to determine the service status of the IP address, wherein the service status includes a restricted status and an unrestricted status.

[0042] As an example, for each IP address in the IP address range corresponding to the currently used PLMN identifier, the currently used IP address is matched with the IP address in the IP address range. If an IP address identical to the currently used IP address is matched, it is determined that the IP address range includes the currently used IP address. In the case where the IP address range corresponding to the currently used PLMN identifier includes the currently used IP address, it is determined that the service state of the currently used IP address is a restricted state. In the case where the IP address range corresponding to the currently used PLMN identifier does not include the currently used IP address, it is determined that the service state of the currently used IP address is an unrestricted state.

[0043] In one embodiment of the present disclosure, after querying the IP address range corresponding to the currently used PLMN identifier in the preset IP pool, if the PLMN identifiers in the preset IP pool are inconsistent with the currently used PLMN identifier, that is, the preset IP pool does not contain the IP address range corresponding to the currently used PLMN identifier, then it is determined that the service status of the currently used IP address is unrestricted.

[0044] In one embodiment of the present disclosure, after querying the IP address range corresponding to the currently used PLMN identifier in the preset IP pool, if the preset IP pool is empty, it is determined that the service status of the currently used IP address is unrestricted.

[0045] Step 103 , in response to the vehicle-mounted terminal attempting to access the network address, access control is performed according to the service status and the network address through the built-in domain name system of the vehicle-mounted terminal.

[0046] In this embodiment, access control is performed based on the service status and network address through the built-in domain name system of the vehicle terminal, including: when the service status is restricted and the network address is not included in the built-in domain name system, the built-in domain name system cannot resolve the network address and denies access to the network address.

[0047] Among them, the vehicle terminal includes a built-in domain name system, and the built-in domain name system is configured to be able to resolve a specific network address, and the network address adopts a URL (Uniform Resource Locator) for example. Optionally, the network address can be added to the built-in domain name system. If the built-in domain name system contains the network address, the built-in domain name system can resolve the network address, otherwise, the built-in domain name system cannot resolve the network address. For example, the built-in domain name system is set with a network address, and the network address attempted to be accessed is matched with the set network address. If the network address that is the same as the network address attempted to be accessed is matched, it is determined that the built-in domain name system contains the network address attempted to be accessed, and the built-in domain name system can resolve the network address. Otherwise, it is determined that the built-in domain name system does not contain the network address attempted to be accessed, and the built-in domain name system cannot resolve the network address.

[0048] As an example, the vehicle manufacturer may set the network address in the built-in domain name system during the installation of the vehicle terminal. In this example, the network address set in the built-in domain name system includes the network address required to be accessed by the Internet of Vehicles service and / or other necessary Internet network addresses, which are not limited here.

[0049] As another example, the user can flexibly set the network address in the built-in domain name system of the vehicle terminal. In this example, the network address set in the built-in domain name system may include an Internet network address set by the user.

[0050] According to the technical solution of the disclosed embodiment, in response to the vehicle-mounted terminal accessing the operator network, the PLMN identifier and IP address currently used by the vehicle-mounted terminal are obtained, and the IP address is matched with the IP address range corresponding to the currently used PLMN identifier in the preset IP pool to determine the service status of the IP address. Furthermore, in response to the vehicle-mounted terminal attempting to access the network address, access control is performed according to the service status and the network address through the built-in domain name system of the vehicle-mounted terminal. When the service status is restricted and the network address is not included in the built-in domain name system, access to the network address is denied. Therefore, by configuring the preset IP pool and the built-in domain name system, the mobile network traffic is controlled in combination with the IP address of the vehicle-mounted terminal and the PLMN of the current network operator, and active management of the mobile network traffic of the vehicle terminal is achieved. While controlling the mobile network traffic of the vehicle terminal, the problem of underlying, non-service-related traffic leakage is solved.

[0051] Based on the above embodiments, Figure 2 A flowchart of another method for controlling network traffic usage of a vehicle terminal provided by an embodiment of the present disclosure is shown in FIG. Figure 2As shown, the built-in domain name system of the vehicle terminal is used to perform access control based on the business status and network address, and also includes:

[0052] Step 201, when the network address is included in the built-in domain name system, the network address is resolved by the built-in domain name system to obtain the target IP address, so as to access the network address according to the target IP address.

[0053] In this embodiment, when the vehicle terminal attempts to access a network address, the vehicle terminal first sends a domain name resolution request to the built-in domain name system of the vehicle terminal, and the built-in domain name system resolves the network address that is attempted to be accessed in combination with the service status of the currently used IP address. If the built-in domain name system contains the network address, the built-in domain name system can resolve the network address, and obtain the corresponding target IP address by resolving the network address to obtain the requested service, thereby enabling access to the network address. If the built-in domain name system does not contain the network address, the built-in domain name system cannot resolve the network address.

[0054] Step 202: When the network address is not included in the built-in domain name system, if the service status is unrestricted, a resolution request for the network address is sent to the external Internet.

[0055] Step 203, receiving the target IP address returned by the external Internet, and accessing the network address according to the target IP address.

[0056] In this embodiment, when the network address is not included in the built-in domain name system, it is determined whether the service status is restricted. If the service status is unrestricted, the vehicle-mounted terminal uses the established bearer to send a domain name resolution request to the external Internet. The external Internet resolves the network address to determine the corresponding target IP address, and returns the target IP address to the vehicle-mounted terminal. Then, the corresponding target IP address is obtained to obtain the requested service, thereby enabling access to the network address.

[0057] In one embodiment of the present disclosure, when a preset traffic control condition is met, a preset IP pool is set or updated, and / or a network address contained in a built-in domain name system is set or updated. The setting or updating of the preset IP pool is triggered and completed by the operator, and the setting or updating of the built-in domain name system is completed by the vehicle manufacturer or the user. Optionally, the prompt information of the vehicle terminal is obtained, and it is determined whether the traffic control condition is met based on the prompt information of the vehicle terminal and the tariff information of different regions / operators. For example, the vehicle terminal generates prompt information based on the statistical traffic usage information to provide to the user, or, when the operator is switched, if the PLMN of the mobile network used by the vehicle terminal changes, prompt information is provided to the user, and the user can learn about the mobile network tariff information of different operators, and then the user can adjust the network address in the built-in domain name system according to the prompt information and tariff information. Currently, the operator network only counts the network traffic usage of the vehicle-mounted terminal and will not interfere with the mobile network traffic usage of the vehicle-mounted terminal. In this embodiment, from the perspective of the vehicle-mounted terminal, the Internet services that the vehicle-mounted terminal can access are managed, thereby realizing the control of mobile network traffic. Furthermore, due to the different mobile network traffic charges in different regions, when the mobile network traffic charge of the vehicle's home operator is higher, or when the vehicle enters the roaming operator network from the home operator network, and the mobile network traffic charge of the roaming operator is higher, the user can be prompted to control the mobile network traffic. For example, the user can continue to use the mobile traffic control strategy of the vehicle terminal in the home operator network.

[0058] The following are examples using actual application scenarios.

[0059] Embodiment 1: The vehicle terminal uses Internet services in the home operator network, and whether or not to restrict Internet services based on the vehicle terminal. Vehicles equipped with vehicle terminals must be used within the coverage of the home operator network. Vehicle users can determine whether it is necessary to control the use of mobile network traffic from the perspective of the vehicle terminal based on their own needs, such as network traffic charges.

[0060] If control is required, the home operator shall allocate a specific IP address range, which corresponds to the PLMN of the home operator. Then, the home operator shall configure the IP address range and its corresponding PLMN identifier into the preset IP pool, and the network address required to be accessed shall be set in the built-in domain name system of the vehicle terminal. The setting of the built-in domain name system can follow the default configuration, or the user can add or reconfigure it in the built-in domain name system according to his or her own Internet usage habits. Based on the above settings, the vehicle terminal can realize the control of mobile network traffic in the network of the home operator.

[0061] When the vehicle terminal accesses the home operator network, the home operator network allocates an IP address for Internet access to the vehicle terminal, and the vehicle terminal determines the service status of the currently used IP address based on the currently used PLMN and the preset IP pool. If the preset IP pool contains the IP address range corresponding to the currently used PLMN, and the currently used IP address is within the IP address range, the service status of the currently used IP address is restricted, otherwise, the service status is unrestricted.

[0062] When the vehicle terminal attempts to access a network address, the vehicle terminal sends the service status and network address to the built-in domain name system. If the network address exists in the built-in domain name system, the built-in domain name system resolves the network address to achieve access. If the network address does not exist in the built-in domain name system, it is determined whether to resolve it based on the service status. If the service status is unrestricted, the network address is resolved through the external Internet to achieve access. If the service status is restricted, the built-in domain name system does not use the established bearer to send a domain name resolution request to the external Internet, and the vehicle terminal cannot obtain the requested service to achieve control.

[0063] If control is not required, the preset IP pool of the vehicle terminal may not include the PLMN identifier of the home operator and its corresponding IP address range, and the user may not modify the network address contained in the built-in domain name system.

[0064] Optionally, for vehicles from the same batch equipped with on-board terminals with the above-mentioned management and control functions, since the vehicles may be sold to different regions, operators in different regions may adopt different mobile network traffic usage strategies. Users can determine whether management and control is needed based on the mobile network traffic usage strategy of the operator in their area and their own needs. Vehicles from the same batch can flexibly configure personalized mobile network traffic control strategies in different operator networks.

[0065] Embodiment 2: The vehicle terminal uses Internet services on the roaming operator network. The IP address used by the vehicle terminal is allocated by the home operator network, and the home operator allocates the IP address range for mobile network traffic control to the vehicle terminal. Vehicles equipped with vehicle terminals can not only be used within the coverage of the home operator network, but also enter areas outside the network coverage of the home operator. If there is a roaming agreement between the home operator and the local operator, the vehicle terminal can access the Internet using the local operator network, that is, using the roaming operator network to access the Internet.

[0066] In this embodiment, when the vehicle terminal accesses the roaming operator network, the home operator network allocates an IP address to the vehicle terminal, such as the following two roaming network architectures: the home operator and the roaming operator adopt a roaming method of home routing, and the IP address is allocated by the home operator network; the home operator and the roaming operator adopt a roaming method of roaming routing, and the IP address is allocated by the home operator network.

[0067] If control is required, the home operator shall allocate a specific IP address range, which corresponds to the PLMN of the roaming operator. The home operator shall configure the IP address range and its corresponding PLMN identifier into the preset IP pool, and the network address required to be accessed shall be set in the built-in domain name system of the vehicle terminal. The settings of the built-in domain name system can follow the default configuration, or the user can add or reconfigure it in the built-in domain name system according to his or her own Internet usage habits. Based on the above settings, the vehicle terminal can realize the control of mobile network traffic in the roaming operator network.

[0068] When the vehicle terminal accesses the roaming operator network, the home operator network allocates an IP address for Internet access to the vehicle terminal, and the vehicle terminal determines the service status of the currently used IP address based on the currently used PLMN and the preset IP pool. If the preset IP pool contains the IP address range corresponding to the currently used PLMN, and the currently used IP address is within the IP address range, the service status of the currently used IP address is restricted, otherwise, the service status is unrestricted.

[0069] In the roaming operator network, when the vehicle terminal attempts to access a network address, the vehicle terminal sends the service status and network address to the built-in domain name system. If the network address exists in the built-in domain name system, the built-in domain name system resolves the network address to achieve access. If the network address does not exist in the built-in domain name system, it is determined whether to resolve it based on the service status. If the service status is unrestricted, the network address is resolved through the external Internet to achieve access. If the service status is restricted, the built-in domain name system does not use the established bearer to send a domain name resolution request to the external Internet, and the vehicle terminal cannot obtain the requested service to achieve control.

[0070] If control is not required, the preset IP pool of the vehicle terminal may not include the PLMN identifier of the roaming operator and its corresponding IP address range, and the user may not modify the network address contained in the built-in domain name system.

[0071] Embodiment 3: The vehicle uses Internet services on the roaming operator network, and the IP address used by the vehicle terminal is allocated by the roaming operator network, and the roaming operator network allocates the IP address range for mobile network traffic control to the vehicle terminal. Vehicles equipped with vehicle terminals can not only be used within the coverage of the home operator network, but also enter areas outside the network coverage of the home operator. If there is a roaming agreement between the home operator and the local operator, the vehicle terminal can access the Internet using the local operator network, that is, using the roaming operator network to access the Internet.

[0072] In this embodiment, when the vehicle terminal accesses the roaming operator network, the roaming operator network allocates an IP address to the vehicle terminal, such as the following roaming network architecture: a roaming method of roaming routing is adopted between the home operator and the roaming operator, and the IP address is allocated by the roaming operator network.

[0073] If control is required, the home operator negotiates with the roaming operator, and the roaming operator allocates a specific IP address range, which corresponds to the PLMN of the roaming operator. The roaming operator configures the IP address range and its corresponding PLMN identifier into the preset IP pool, and the built-in domain name system of the vehicle terminal is set with the network address to be accessed. The settings of the built-in domain name system can use the default configuration, or the user can add or reconfigure it in the built-in domain name system according to his or her own Internet usage habits. Based on the above settings, the vehicle terminal can realize the control of mobile network traffic in the roaming operator network.

[0074] When the vehicle terminal accesses the roaming operator network, the roaming operator network allocates an IP address to the vehicle terminal, and the vehicle terminal determines the service status of the currently used IP address based on the currently used PLMN and the preset IP pool. If the preset IP pool contains the IP address range corresponding to the currently used PLMN, and the currently used IP address is within the IP address range, the service status of the currently used IP address is restricted, otherwise, the service status is unrestricted.

[0075] In the roaming operator network, when the vehicle terminal attempts to access a network address, the vehicle terminal sends the service status and network address to the built-in domain name system. If the network address exists in the built-in domain name system, the built-in domain name system resolves the network address to achieve access. If the network address does not exist in the built-in domain name system, it is determined whether to resolve it based on the service status. If the service status is unrestricted, the network address is resolved through the external Internet to achieve access. If the service status is restricted, the built-in domain name system does not use the established bearer to send a domain name resolution request to the external Internet, and the vehicle terminal cannot obtain the requested service to achieve control.

[0076] If control is not required, the preset IP pool of the vehicle terminal may not include the PLMN identifier of the roaming operator and its corresponding IP address range, and the user may not modify the network address contained in the built-in domain name system.

[0077] As a result, network traffic usage control of the vehicle terminal in non-roaming scenarios and roaming scenarios is achieved.

[0078] Figure 3 A schematic diagram of a network traffic usage control device for a vehicle terminal provided by an embodiment of the present disclosure is shown in FIG. Figure 3 As shown, the network traffic usage control device of the vehicle-mounted terminal includes: an acquisition module 31, a determination module 32, and a control module 33.

[0079] An acquisition module 31 is used to acquire a PLMN identifier and an IP address currently used by the vehicle-mounted terminal in response to the vehicle-mounted terminal accessing the operator network;

[0080] A determination module 32, configured to query the preset IP pool for an IP address range corresponding to the currently used PLMN identifier, and to match the IP address with the IP address range to determine the service status of the IP address;

[0081] A control module 33, for responding to the vehicle terminal attempting to access the network address, and performing access control according to the service status and the network address through the built-in domain name system of the vehicle terminal;

[0082] Among them, when the service status is restricted and the network address is not included in the built-in domain name system, the built-in domain name system cannot resolve the network address and denies access to the network address.

[0083] In one embodiment of the present disclosure, the determination module 32 is specifically configured to:

[0084] Match the IP address with the IP address range to determine the service status of the IP address, including:
