With the popularization of these new functions or services of the Internet of Vehicles, the requirements of mobile communication services by car companies and users have changed from optional configurations to default requirements, and higher and higher requirements have been placed on the quality of mobile communication services. At present, the network coverage of a single communication operator is uneven.

The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0068] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0069] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure.

[0070] Example 1

[0071] The present invention adopts a method for switching available operators in manual and automatic modes. By designing a policy management and policy execution architecture, manual and automatic policy parameters are managed, and these policies are executed according to user selection or network environment. The economy of operator selection and high availability requirements are taken into account, helping intelligent connected vehicles to achieve high-availability networking functions.

[0072] The present invention includes two parts: strategy management and strategy execution. The strategy management is mainly used to manage the conditions and parameters required for switching execution, and the strategy execution is to execute specific switching according to the network environment where the user and the vehicle are located.

[0073] like Figure 1 As shown, the disclosure proposes one aspect of the present invention, which is to propose a high-availability network design method for intelligent networked vehicles, comprising the following steps:

[0074] S100, configuring a communication card on the TBOX of the vehicle, and presetting card data of two or more operators in the communication card;

[0075] Communication card, using eUICC card or dual SIM single standby mode. Preset two or more operators' card data (profile) in the eUICC card or dual SIM card to facilitate switching operators according to user selection or network quality.

[0076] The present invention can use eUICC card or dual-card single standby mode as the operator bearer of policy management and policy execution. The following will respectively describe the operator management switching of the present invention for eUICC card or dual-card single standby mode. Among them, as a vehicle network system, its internal communication module such as 4G / 5G module, and system facilities such as TBOX are prior art, and their specific functions will not be repeated here.

[0077] like Figure 2 As shown, an implementation scheme of using an eUICC card for operator management switching. As an optional implementation scheme of the present invention, optionally, in step S100, configuring a communication card on the TBOX of the vehicle and presetting card data of two or more operators in the communication card includes:

[0078] S101, configuring an eUICC card on the vehicle;

[0079] S102, pre-installing card data of two or more operators in the eUICC card, and configuring the eUICC card on the TBOX;

[0080] S103: Connect the eUICC card to the communication module in the TBOX according to the first preset communication interface.

[0081] An eUICC card is configured on the TBOX of each vehicle. Two or more operator card data (Profile) are preset in the eUICC card or dual cards. Because the eUICC card is a large-capacity SIM card with remote management and local management functions, it can store the card data (Profile) of multiple operators at the same time. The operator card data can be switched through the local management function. When designing the hardware, the eUICC can be used to replace the original SIM card.

[0082] like Figure 3 As shown, it is a mode of using a SIM card to switch operators. As an optional implementation of the present invention, optionally, in step S100, configuring a communication card on the TBOX of the vehicle and presetting card data of two or more operators in the communication card include:

[0083] S101, configuring two or more SIM cards on the vehicle;

[0084] S102, pre-installing the operator's card data in the SIM card, and configuring the SIM card on the TBOX;

[0085] S103, connecting the SIM card to the communication module in the TBOX according to the second preset communication interface.

[0086] The dual-SIM single-standby mode refers to using the multi-SIM card function of the communication module. During hardware design, two SIM cards from different operators are connected to the communication module, and different SIM cards are selected through the control interface of the communication module.

[0087] The following will specifically describe an implementation method for switching communication cards for communication according to the configured operator switching management policy.

[0088] S200, presetting a handover management strategy for conditions and parameters required for handover of operators and a handover execution strategy for specifically executing the handover management strategy, and configuring both the handover management strategy and the handover execution strategy on the TBOX;

[0089] Here, a switching management strategy is configured on the TBOX of the vehicle-mounted system, and a switching management strategy module is established accordingly; and a switching execution strategy is configured, and a switching strategy execution module is established accordingly. Specifically, the present invention includes two parts: strategy management and strategy execution. Strategy management is mainly used to manage the conditions and parameters required for switching execution, and strategy execution is to perform specific switching according to the network environment in which the user and the vehicle are located. In terms of implementation, the operator switching mode is mainly divided into manual switching mode and automatic switching mode. During manual switching, the operator is selected according to the switching instruction input by the user through the THU, and the operator is manually restored and switched according to the input switching recovery instruction. Automatic switching is based on the remote management system configured on the background management platform such as the cloud platform to monitor the network operation status of the vehicle, and automatically implement the switching of the operator according to the configured automatic switching strategy, and implement the recovery switching of the operator according to the automatic switching recovery strategy. The switching management strategy and the switching execution strategy are both configured on the TBOX.

[0090] S300, obtaining the network environment in which the user and the vehicle are located, inputting a switching instruction according to the network environment in which the user and the vehicle are located, and executing the switching execution strategy.

[0091] According to the selected manual switching mode and automatic switching mode, for example, according to the switching instruction manually input by the user, or the switching instruction obtained by judging the network environment in which the user and the vehicle are located, the corresponding configured switching strategy, that is, the switching execution strategy, is executed to realize the switching of operators.

[0092] The following describes in detail the operator switching modes and usage methods of different modes.

[0093] like Figure 4As shown, a manual switching control mode is set. As an optional implementation of the present invention, optionally, in step S200, the switching management strategy for presetting the conditions and parameters required by the switching operator and the switching execution strategy for specifically executing the switching management strategy, and configuring both the switching management strategy and the switching execution strategy on the TBOX, include:

[0094] S201, presetting a first strategy establishment rule;

[0095] S202: Establishing rules according to the first strategy, setting and establishing a manual mode switching strategy, including:

[0096] Primary and backup operator strategy P1 is used to select the primary and backup operators from a technical and business perspective;

[0097] The manual switching recovery strategy P2 is used to implement the recovery switching of the primary operator or the backup operator according to the switching recovery command input by the user in the manual switching mode. P2 includes timed recovery, next ignition recovery and never recovery;

[0098] S203, configuring both P1 and P2 on the TBOX, establishing a manual switching interface corresponding to and matching P2, and configuring the manual switching interface on the IHU.

[0099] First, a manual mode switching strategy is established according to the rules of the first strategy. The first strategy establishment rules can be customized according to the user's control rules for manual switching as long as they can satisfy the user's ability to manually switch operators. This is not limited here. The following second strategy establishment rules are the same. Among them, the manual mode switching strategy includes: the primary and backup operator strategy P1: from a technical and business perspective, select the primary operator and the backup operator; the manual switching recovery strategy P2: including timed recovery (for example, 1 day, 7 days, 30 days), next ignition recovery, and never recovery.

[0100] Secondly, both P1 and P2 are configured on the TBOX, and a manual switching interface corresponding to the P2 is established, and the manual switching interface is configured on the IHU. The manual switching interface facilitates the user to manually input the switching instruction through the IHU, and send the switching instruction to the switching strategy execution module to match the specific strategy in the manual mode switching strategy. As an optional implementation scheme of the present invention, optionally, in step S300, the network environment of the user and the vehicle is obtained, and the switching instruction is input according to the network environment of the user and the vehicle, and the switching execution strategy is executed, including:

[0101] S301, obtaining an operator switching instruction input by a user through the manual switching interface to implement a manual switching mode;

[0102] S302: Implement switching between the primary operator and the backup operator according to the operator switching instruction;

[0103] S303: In the manual switching mode, according to the switching recovery instruction input by the user, the P2 is matched and executed to implement the recovery switching of the primary operator or the backup operator.

[0104] Specifically, Figure 4 The manual switching state transition diagram shown:

[0105] When a user is not satisfied with the service of the current operator, the user can choose to switch to an alternative operator through the central control large screen (Infotainment Head Unit, IHU) interface.

[0106] On the one hand, after the switch is successful, the vehicle uses the network service provided by the backup operator. The user can choose to switch back to the primary operator again through the IHU.

[0107] On the other hand, after the switch is successful, the vehicle can also switch back to the primary operator at a specified time according to the manual switch recovery strategy P2. When P2 specifies never to recover, no switch is performed.

[0108] On the other hand, after the switch is successful, for example, after the vehicle switches back to the primary operator according to the automatic switch strategy, there is no need to execute the recovery strategy P2 of the manual switch.

[0109] like Figure 5 The figure shows a control flow diagram of the automatic switching mode. The cloud needs to judge the collected data such as the vehicle network quality to determine whether it meets the configured automatic switching strategy, and then perform the automatic switching operation. Specifically, as an optional implementation scheme of the present invention, optionally, in step S200, the switching management strategy for the conditions and parameters required for switching operators and the switching execution strategy for specifically executing the switching management strategy are preset, and the switching management strategy and the switching execution strategy are configured on the TBOX, and also include:

[0110] S210, presetting a second strategy establishment rule;

[0111] S220: Establishing rules according to the second strategy, setting and establishing an automatic mode switching strategy, including:

[0112] The switching strategy P3 of automatic switching is used to realize automatic switching of the primary operator or the backup operator according to the network environment of the user and the vehicle. P3 includes the switching parameters of the primary operator and the backup operator, the switching threshold and hysteresis time of the communication network quality, the switching threshold and hysteresis time of the service network quality, and the maximum value and validity period of the ping-pong switching avoidance counter;

[0113] The automatic switching recovery strategy P4 is used to realize the automatic recovery switching of the primary operator or the backup operator according to the automatic switching switching strategy P3 in the automatic switching mode. P4 includes timed recovery, next ignition recovery and never recovery;

[0114] S230, configuring both P3 and P4 on the TBOX, establishing a switching strategy remote management module corresponding to and matching P3 and P4, and configuring the switching strategy remote management module on a cloud platform.

[0115] First, set the automatic switching strategy, including: automatic switching switching strategy P3: including the switching parameters of the primary and backup operators, including the switching threshold and delay time of the wireless network quality (such as RSRP, RSRQ, SINR), the switching threshold and delay time of the service network quality (latency, availability), the maximum value and validity period of the ping-pong switching avoidance counter; automatic switching recovery strategy P4: including timed recovery (for example, 1 day, 7 days, 30 days), next ignition recovery, and never recovery.

[0116] Secondly, both P3 and P4 are configured on the TBOX, and a switching strategy remote management module corresponding to and matching P3 and P4 is established, and the switching strategy remote management module is configured on a cloud platform.

[0117] In order to realize the automatic switching operation, in this embodiment, the TBOX of the vehicle is controlled remotely by the cloud. A switching strategy remote management module matching the automatic switching strategy is established on the cloud platform to realize the control of the switching strategy management module.

[0118] Specifically, as an optional implementation scheme of the present invention, optionally, in step S300, the obtaining of the network environment in which the user and the vehicle are located, inputting a switching instruction according to the network environment in which the user and the vehicle are located, and executing the switching execution strategy includes:

[0119] S310, obtaining the communication network quality and the service network quality of the vehicle through the switching strategy remote management module;

[0120] S320: Determine whether the network environment of the vehicle meets the P3 requirements or whether there are any abnormalities in the network channel of the operator according to the communication network quality and the service network quality; specifically, determine whether the vehicle meets the following conditions at the same time: (1) the switching condition is met: the wireless network quality is lower than the switching threshold and hysteresis time in P3; or the service network quality is lower than the switching threshold and hysteresis time in the automatic switching strategy P3; (2) there is no ping-pong switching: the ping-pong switching avoidance counter in the automatic switching strategy P3 does not reach the maximum value within the validity period;

[0121] S330: According to the judgment result, match and execute P3 to realize automatic switching of the operator of the vehicle.

[0122] like Figure 5 As shown, through the switching strategy remote management module, the communication network quality and business network quality of the vehicle are obtained, and it is judged and learned whether the network environment of the vehicle meets the requirements or whether there are any abnormalities in the operator's network channel. Specifically, it is necessary to judge whether the vehicle meets the following conditions at the same time:

[0123] (1) Whether the switching conditions are met: the wireless network quality (such as RSRP, RSRQ, SINR) is lower than the switching threshold in the automatic switching strategy P3 and meets the delay time; or the service network quality (latency, availability) is lower than the switching threshold in the automatic switching strategy P3 and meets the delay time; (2) There is no ping-pong switching: the ping-pong switching avoidance counter in the automatic switching strategy P3 does not reach the maximum value within the validity period.

[0124] If all conditions are met, the system switches to the backup operator.

[0125] As an optional implementation scheme of the present invention, optionally, in step S300, the obtaining of the network environment in which the user and the vehicle are located, inputting a switching instruction according to the network environment in which the user and the vehicle are located, and executing the switching execution strategy further includes:

[0126] S311. Obtaining an operator switching instruction input by a user through the manual switching interface;

[0127] S321, automatically switching and matching and executing P4 according to the operator switching instruction, to achieve automatic recovery switching of the operator;

[0128] S331, execute step S310 in a loop.

[0129] During the automatic switching process, if you want to switch manually, you need to input the switching command through the IHU. At this time, you need to change the execution strategy of the switching mode. Specifically:

[0130] On the one hand, after the switch is successful, the vehicle can use the network services provided by the backup operator. If the user needs to switch, the user can manually choose to switch back to the primary operator through the IHU. After the switch is successful, the vehicle switches back to the primary operator at the specified time according to the automatic switching recovery strategy P4. When P4 specifies never to recover, no switch is performed.

[0131] On the other hand, after the switch is successful, the vehicle can continue to monitor the quality of the wireless network and the service network. According to the above step S310, the vehicle's communication network quality and service network quality can continue to be monitored to continuously determine and learn whether the vehicle's network environment meets the requirements or whether there are any abnormalities in the operator's network channel. According to the judgment result, the primary operator is switched back through the configured strategy.
