[0072] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0073] It should be noted that all actions of acquiring signals, information or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where they are located, and with the authorization given by the owner of the corresponding device.

[0074] Figure 1 is a flow chart of a communication method shown in an exemplary embodiment of the present disclosure; Figure 1 As shown, the communication method is applied to a vehicle-mounted terminal, the vehicle-mounted terminal includes multiple APNs for Internet access, and the method may include:

[0075] Step 101, determine the target service corresponding to the link where each APN is currently located.

[0076] In this step, you can first determine the currently running services, and then determine the APN identifier corresponding to each service, so as to obtain the corresponding relationship between each APN identifier and the target service; you can also determine the target service corresponding to the link where each APN is currently located by checking the APN configuration information. The configuration information may include APN type, server address, port number, protocol type, user name, password, etc.

[0077] Step 102, obtaining the current safety status of the vehicle.

[0078] The safety status is used to indicate whether the vehicle needs rescue.

[0079] In this step, it can be determined whether the distress signal of the vehicle is received. If it is determined that the distress signal is received, it is determined that the vehicle needs rescue. The distress signal can be triggered by the SOS button on the current vehicle, and can also be reported by other vehicles. For example, when the current vehicle is in a state of waiting for rescue, the rescue signal is transmitted through lights. After other vehicle users obtain the rescue signal, they report the distress signal through their own vehicles.

[0080] Step 103: Determine first priority information of the plurality of target services corresponding to the plurality of APNs for Internet access.

[0081] In this step, in a possible implementation, preset priority data may be obtained, the preset priority data including specified priorities of a plurality of preset services; the priority of each target service is determined according to the preset priority data to obtain the first priority information.

[0082] The first priority information is the priority order of each preset service when the vehicle does not need rescue.

[0083] For example, the preset priority data includes multiple designated services that may be involved in the vehicle terminal, and the priority order of each designated service. For example, it may include service A, service B, service C, service D, service E, service F, service G, service H and service I, where the priority order of service AI is ADEHIFGBC, that is, A has the highest designated priority, D has a designated priority lower than A and higher than E, E has a designated priority lower than D and higher than H, I has a designated priority lower than H and higher than F, B has a designated priority lower than G and higher than C, and C has the lowest designated priority.

[0084] In another possible implementation, the priority order of each target service can be determined according to the order of service request times of different services to obtain the first priority information. For example, the earlier the service request time, the lower the priority, and the later the service request time, the higher the priority; or the later the service request time, the lower the priority.

[0085] Step 104: Allocate data resources of the link where each APN is located according to the security status and the first priority information.

[0086] The safety status may include a state waiting for rescue and a state not waiting for rescue.

[0087] In this step, when the safety state is a waiting for rescue state, the resource requirements of rescue-related data transmission services can be prioritized. When the data resource requirements of rescue-related data transmission services are met, data resources are provided for each APN link according to the priority order in the first priority information.

[0088] The above technical scheme can allocate data resources of the link where each APN is located according to the current safety status of the vehicle and the first priority information of multiple target services corresponding to the multiple APNs currently used for Internet access. It can reasonably and effectively allocate data resources based on the current safety status of the vehicle, which can improve the safety performance of the vehicle, and thus help improve the vehicle user experience.

[0089] Figure 2 is based on Figure 1 The embodiment shown is a flow chart of a communication method; Figure 2 As shown, Figure 1 The implementation method of allocating data resources of the link where each APN is located according to the security status and the first priority information in step 104 may include:

[0090] Step 1041: When it is determined that the vehicle is currently in the state to be rescued, determine the service type of each target service.

[0091] The service type may include rescue data transmission services and non-rescue data transmission services. The service type may be pre-set in the form of service attributes. This step may obtain the service type by acquiring attribute data of each target service.

[0092] Step 1042: Determine second priority information of a plurality of target services corresponding to the plurality of APNs for Internet access according to the first priority information and the service type of each of the target services.

[0093] Wherein, the service type includes rescue data transmission service, and this step can be performed by Figure 3 The steps S11 to S13 are implemented, Figure 3 is based on Figure 2 The embodiment shown is a flow chart of a communication method; Figure 3 As shown, this step may include:

[0094] S11, determining, according to the first priority information, a first standby priority level of the rescue data transmission service among the multiple target services corresponding to the multiple APNs for Internet access.

[0095] For example, if the multiple APNs used for Internet access are APN1, APN2, APN3 and APN4, the link where APN1 is located is responsible for the vehicle status information data transmission service (for example, service A), which belongs to the rescue data transmission type service, the link where APN2 is located is responsible for the entertainment service service of the vehicle audio and video system (service F), which belongs to the non-rescue data transmission type service, the link where APN3 is located is responsible for the OTA package download service (service B), which also belongs to the non-rescue data transmission type service, and the link where APN4 is located is responsible for the occupant's physical status data transmission service after a vehicle collision (service C), which belongs to the rescue data transmission service; that is, the target service corresponding to the links where APN1 and APN4 are located is the rescue data transmission type service, and according to the priority order ADEHIFGBC in the first priority information, it can be determined that the first standby priority of the target service corresponding to the links where APN1 and APN4 are located is that the service of the link where APN1 is located is higher than the service of the link where APN4 is located.

[0096] S12: Determine, according to the first priority information, a second standby priority of other services among the multiple target services corresponding to the multiple APNs for Internet access except the rescue data transmission service.

[0097] For example, still taking the example in S11 as an example, among the multiple target services corresponding to the multiple APNs for Internet access, other services except the rescue data transmission service are the entertainment service service (service F) of the vehicle audio and video system responsible for the link where APN2 is located and the OTA package download service (service B) responsible for the link where APN3 is located. According to the first priority information (ADEHIFGBC), it can be determined that the priority of service F is higher than that of service B, that is, the priority of the target service responsible for the link where APN2 is located is higher than the priority of the target service responsible for the link where APN3 is located.

[0098] S13: Determine the second priority information according to the first standby priority and the second standby priority.

[0099] In this step, the first standby priority level may be set higher than the second standby priority level, thereby obtaining the second priority level information.

[0100] For example, still taking the examples in S11 and S12 as an example, the first standby priority is that service A is higher than service C, that is, the priority of the target service that the link where APN1 is located is higher than the priority of the target service that the link where APN4 is located is responsible for, and the second standby priority is that the priority of service F is higher than service B, that is, the priority of the target service that the link where APN2 is located is higher than the priority of the target service that the link where APN3 is located is responsible for. Since the first standby priority is higher than the second standby priority, the priority order in the second priority information is ACFB, that is, the priority of service A is higher than that of service C, the priority of service C is higher than that of service F, and the priority of service F is higher than that of service B.

[0101] Step 1043: allocate data resources of the link where each APN is located according to the second priority information.

[0102] A possible implementation of this step is: when it is determined that the vehicle-mounted terminal is in a dual-card dual-pass state, obtain the first signal quality of the first communication card and the second signal quality of the second communication card; when at least one of the first signal quality and the second signal quality does not meet the preset quality requirements, determine a target communication card with better quality between the first signal quality and the second signal quality; and allocate data resources according to the second priority information through the target communication card.

[0103] Wherein, when it is determined that the vehicle terminal supports DSDA (Dual SIM Dual Active) and is registered on DSDA, it is determined that the vehicle terminal is in a dual SIM dual active state. The first communication card and the second communication card may be SIMs (Subscriber Identity Modules) of the same operator or different operators, the first signal quality and the second signal quality may both include parameters such as signal strength, signal-to-noise ratio, and reference signal received power, and the preset quality requirements may include a required range of signal strength, a required range of signal-to-noise ratio, and a required range of reference signal received power.

[0104] It should be noted that the implementation method of determining the target communication card with better quality between the first signal quality and the second signal quality described above may be that, when the difference between the signal strength of the first communication card and the signal strength of the second communication card is greater than a first preset positive value, the first signal quality is better, and the first communication card is used as the target communication card; when the difference between the signal strength of the first communication card and the signal strength of the second communication card is less than a first preset negative value, the second signal quality is better, and the second communication card is used as the target communication card; when the difference between the signal strength of the first communication card and the signal quality of the second communication card is greater than a first preset negative value and less than the first preset positive value, the target communication card is determined based on the signal-to-noise ratio of the first communication card and the signal-to-noise ratio of the second communication card. When the absolute value of the difference between the signal-to-noise ratio of the first communication card and the signal-to-noise ratio of the second communication card is less than a preset absolute value threshold, the target communication card is determined according to the magnitude of the reference signal received power; when the difference between the signal-to-noise ratio of the first communication card and the signal-to-noise ratio of the second communication card is greater than a second preset positive value, the first signal quality is better, and the first communication card is used as the target communication card; when the difference between the signal-to-noise ratio of the first communication card and the signal-to-noise ratio of the second communication card is less than a second preset negative value, the second signal quality is better, and the second communication card is used as the target communication card.

[0105] Another possible implementation is: the vehicle terminal is in a dual-card dual-pass state, the links where the multiple APNs for Internet access are located are provided with data resources by the first communication card, the first signal quality includes a first transmission delay duration, and the second signal quality includes a second transmission delay duration;

[0106] When both the first signal quality and the second signal quality meet the preset quality requirements, if it is determined that the transmission delay duration of the first communication card is greater than or equal to the specified duration, the first APN link to be deployed is determined, and the first APN link to be deployed is switched to the second communication card, and the second communication card provides data resources to the first APN link to be deployed; wherein, the first APN link to be deployed is the APN link corresponding to a specified number of target services with the lowest priority in the second priority information.

[0107] Optionally, after the second communication card provides data resources to the first APN link to be deployed, the method may further include:

[0108] When the delay duration of the second communication card is less than the specified duration and the delay duration of the first communication card is greater than the specified duration, a second APN link to be deployed is determined, and the second APN link to be deployed is switched to the second communication card, and the second communication card provides data resources to the second APN link to be deployed; wherein the second APN link to be deployed is the APN link corresponding to a specified number of target services with the highest priority in the second priority information.

[0109] Optionally, after the second communication card provides data resources to the second APN link to be deployed, the method further includes:

[0110] If the delay duration of the second communication card is greater than or equal to the specified duration, the first APN link to be deployed is switched to the first communication card, and the first communication card provides data resources to the first APN link to be deployed.

[0111] In another implementation, if the vehicle terminal is in a DSDS (Dual SIM Dual Standby) state or a single-SIM state, the data resource demand of each APN link can be met in turn according to the second priority information.

[0112] The above technical solution can allocate data resources according to the principle of giving priority to rescue data transmission services when the vehicle is in a rescue state, ensuring that the APN link where the rescue data transmission services are located has the highest priority, thereby effectively improving the vehicle's safety performance and facilitating the improvement of the vehicle's user experience.
