Description

Technical Field

[0001] The embodiments of the present disclosure relate to the field of vehicle network communications, and in particular to a method, apparatus, device, and storage medium for locally updating an FPLMN. Background Art

[0002] In vehicle-to-vehicle communications, the Forbidden Public Land Mobile Network (FPLMN) list is used to prevent vehicles from connecting to unavailable networks. However, in some cases, the FPLMN list may need to be updated. For example, when a vehicle roams to a new country, the PLMNs previously marked as unavailable may be based on experience in the original country, but in the new country, these PLMNs may not be a problem at all, so an update of the FPLMN list is required.

[0003] In the related art, users are typically required to manually update the FPLMN list or wait for the FPLMN list to automatically expire. However, manually updating the FPLMN list is cumbersome and, if the FPLMN list needs to be updated for a large number of vehicles and is distributed over a wide area, requires significant manpower and material resources. Waiting for the FPLMN list to automatically expire takes a long time, resulting in delayed FPLMN list updates. Therefore, a simple and timely method for updating the FPLMN list is urgently needed. Summary of the Invention

[0004] In order to solve the above technical problems or at least partially solve the above technical problems, the embodiments of the present disclosure provide a method, apparatus, device and storage medium for locally updating an FPLMN.

[0006] After the vehicle is powered on, obtain the vehicle's current FPLMN list;

[0007] stationing at least one current FPLMN in the current FPLMN list;

[0008] In a case where the vehicle successfully camps on a target FPLMN in the at least one current FPLMN, the target FPLMN is deleted from the current FPLMN list.

[0009] A second aspect of an embodiment of the present disclosure provides a device for locally updating an FPLMN, the device including:

[0010] A first acquisition module is used to obtain the current FPLMN list of the vehicle after the vehicle is powered on;

[0011] A first stationing module, configured to station at least one current FPLMN in the current FPLMN list;

[0012] The first deleting module is configured to delete the target FPLMN from the current FPLMN list when the vehicle successfully camps on the target FPLMN in the at least one current FPLMN.

[0013] A third aspect of an embodiment of the present disclosure provides an electronic device, which includes: a processor and a memory, wherein a computer program is stored in the memory, and when the computer program is executed by the processor, the processor executes the method of the first aspect above.

[0014] A fourth aspect of an embodiment of the present disclosure provides a computer-readable storage medium, in which a computer program is stored. When the computer program is executed by a processor, the method of the first aspect described above can be implemented.

[0015] The technical solution provided by the embodiments of the present disclosure has the following advantages over the prior art:

[0016] The disclosed embodiment can obtain the vehicle's current FPLMN list after the vehicle is powered on; perform network stationing on at least one current FPLMN in the current FPLMN list; and, if the vehicle successfully stations on a target FPLMN in at least one current FPLMN, delete the target FPLMN from the current FPLMN list. Thus, the above technical solution can automatically and timely update the current FPLMN list locally, eliminating the need for users to manually update the FPLMN list or wait for a long time for the FPLMN list to automatically expire, thereby improving the convenience and timeliness of FPLMN list updates.

[0023] 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 therein can be combined with each other in the absence of conflict.

[0024] 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.

[0025] Figure 1 This is a flow chart of a method for locally updating FPLMN provided by an embodiment of the present disclosure. The method can be executed by an electronic device. The electronic device can be exemplarily understood as a device such as a telematics box (T-BOX). Figure 1 As shown, the method provided in this embodiment includes the following steps:

[0026] S110: After the vehicle is powered on, obtain the current FPLMN list of the vehicle.

[0027] Specifically, the current FPLMN list refers to the current FPLMN list of the vehicle.

[0028] In some embodiments, the current FPLMN list of the vehicle is obtained immediately after the vehicle is powered on.

[0029] In other embodiments, after the vehicle is powered on, if a first preset condition is met, the current FPLMN list of the vehicle is obtained, wherein the first preset condition includes at least one of the following: a first preset time has passed since the last acquisition of the FPLMN list, a user-triggered FPLMN list acquisition request is received, the network quality of the PLMN to which the vehicle is currently connected is less than a preset threshold, or the vehicle is disconnected from the network.

[0030] Specifically, the first preset condition may be any condition that can trigger the electronic device to obtain the current FPLMN list after the vehicle is powered on.

[0031] Specifically, the specific value of the first preset duration can be set by those skilled in the art according to actual conditions and is not limited here.

[0032] Specifically, a specific triggering method of the FPLMN list acquisition request may include touching an FPLMN list acquisition control, voice inputting an FPLMN list acquisition instruction, etc., but is not limited thereto.

[0033] Specifically, network quality indicators include, but are not limited to, signal strength, signal quality, network latency, network speed, and packet loss rate. Accordingly, preset thresholds include, but are not limited to, signal strength thresholds, signal quality thresholds, network latency thresholds, network speed thresholds, and packet loss rate thresholds, but are not limited thereto.

[0034] It can be understood that by setting it up so that after the vehicle is powered on, if the first preset condition is met, the current FPLMN list is obtained and then an attempt to stay on the network is made, it is possible to avoid frequent acquisition of the current FPLMN list and attempts to stay on the network, thereby avoiding unnecessary failed attempts and reducing the waste of power and resources.

[0035] S120: Station at least one current FPLMN in the current FPLMN list.

[0036] Specifically, the current FPLMN refers to the FPLMN included in the current FPLMN list. Specifically, stationing refers to the vehicle's attempt to connect to and remain on a specific PLMN. Stationing is the process of establishing initial contact between the vehicle and the network, which involves selecting an appropriate network for connection. Once the vehicle is successfully stationed, it must register with the network to legally initiate and receive communications on that network.

[0037] It should be noted that there are many specific implementations for stationing at least one current FPLMN. Typical examples are described below, but do not constitute a limitation to the present disclosure.

[0038] In some embodiments, camping on at least one current FPLMN in the current FPLMN list includes:

[0039] S121. Determine the network priority of the current FPLMN in the current FPLMN list.

[0040] Specifically, the stationing priority is used to represent the order in which the current FPLMN is attempted to be stationed. The higher the stationing priority, the earlier the vehicle attempts to station on the FPLMN.

[0041] In some examples, the current FPLMN list includes emergency call networks and non-emergency call networks, wherein the on-network priority of the emergency call network is higher than the on-network priority of the non-emergency call network.

[0042] Specifically, the emergency call network refers to those PLMNs that are specially configured and support emergency call services (such as the eCall system).

[0043] It can be understood that setting the priority of the emergency call network to be higher than that of the non-emergency call network allows the vehicle to try to register on the emergency call network first, thereby increasing the probability of the vehicle subsequently registering on the emergency call network and thus improving driving safety.

[0044] In some examples, the current FPLMN list includes an emergency call network, wherein S121 includes: determining the network priority of the emergency call network in the current FPLMN according to the preset priority strategy corresponding to the emergency call network, wherein the preset priority strategy includes: the network priority of the independent network is higher than the network priority of the cellular network, the network priority of the cellular network is higher than the network priority of the satellite communication, and the network priority of the satellite communication is higher than the network priority of the WIFI.

[0045] Specifically, when the current FPLMN includes multiple emergency call networks of the same type, other priority strategies can be used to further set the on-network priority for the emergency call networks of the same type. For example, for emergency call networks of the same type, their on-network priority can be set according to the time when they join the current FPLMN list, wherein the on-network priority is positively correlated or negatively correlated with the time when they join the current FPLMN list. For another example, for emergency call networks of the same type, their historical network connection data and current context data can be obtained, wherein the current context data includes the current geographic location, the current driving route, the current SIM card operator and the user's network preference, and then based on the historical network connection data and the current context data, their on-network priority is determined (refer to S1211 and S1212 in the following text, which will not be repeated here). For another example, for the same type of emergency call network, if the "current PLMN list of other vehicles and basic vehicle information" broadcasted by other vehicles is received, the network priority of the emergency call network not included in the "current PLMN list of other vehicles with the same basic information as one's own vehicle" is higher than the network priority of the emergency call network included in the "current PLMN list of other vehicles with the same basic information as one's own vehicle". For another example, for the same type of emergency call network, if the "target FPLMN of other vehicles and basic vehicle information" broadcasted by other vehicles is received, the network priority of the "target FPLMN of other vehicles with the same basic information as one's own vehicle" is higher than the network priority of other emergency call networks. But it is not limited to this.

[0046] As you can understand, an independent network refers to a secure, dedicated network designed specifically for critical missions. Setting the independent network's priority to the highest allows it to be prioritized for connection attempts. This helps ensure quick and reliable connection with emergency services in the event of an accident or other emergency, improving rescue efficiency and passenger safety. Cellular networks offer wide coverage and relatively stable service quality, making them suitable for most everyday communication needs. Setting it to a priority just below the independent network allows it to be prioritized for connection attempts after the independent network. This ensures that basic communication needs are met while fully utilizing existing public infrastructure. Satellite communications can provide connectivity in remote areas or areas beyond cellular network coverage. Setting it to a priority below cellular networks but above Wi-Fi allows for essential communication support in areas without cellular network coverage, avoiding the risk of complete loss of connection. While Wi-Fi may offer high data speeds, it has limited coverage and is less secure than cellular and independent networks, so it is given the lowest priority. This ensures that vehicles first attempt to connect to more stable and secure options, only resorting to Wi-Fi when no other options are available. This helps enhance the reliability of the overall communication system.

[0047] In some examples, the current FPLMN list includes non-emergency call networks, and S121 includes: S1211, obtaining historical network connection data and current context data of non-emergency call networks in the current FPLMN, wherein the current context data includes the current geographic location, current driving route, current SIM card operator, and user networking preferences.

[0048] Specifically, historical network connection data is used to characterize the historical connection status of the network, and its indicators include but are not limited to: signal strength, signal quality, network delay, network speed, packet loss rate, and traffic cost (the cost of using the network, such as whether it is free or whether it exceeds the package traffic).

[0049] Specifically, the current geographical location of the vehicle (ie, the current geographical location) belongs to the position information, and the current driving route belongs to the path information, which provide data on the vehicle's position and moving direction.

[0050] Specifically, the current SIM card operator provides the operator to which the SIM card currently used by the vehicle belongs.

[0051] Specifically, user networking preferences are characteristics of user networking behavior, including information about the user's network selection (such as whether to prioritize independent networks or cellular data), data consumption habits, and other aspects.

[0052] S1212: Determine the network priority of the non-emergency call network in the current FPLMN list based on the historical network connection data and the current situation data.

[0053] It should be noted that there are many specific implementations of S1212. Typical examples are described below, but they do not constitute a limitation to the present disclosure.

[0054] In an example, S1212 includes: S12121. For each non-emergency call network in the current FPLMN list, calculate the historical connection score based on the weights corresponding to each indicator in the historical network connection data; S12122. For each non-emergency call network in the current FPLMN list, determine its coverage stability in the current geographic location and the geographic location to be passed in the current driving route, and then determine the coverage stability score; S12123. For each non-emergency call network in the current FPLMN list, determine the operator matching score based on whether it belongs to the current SIM card operator; S12124. For each non-emergency call network in the current FPLMN list, determine the user's preference for it, and then determine the user preference score; S12125. For each non-emergency call network in the current FPLMN list, add up the weighted historical connection score, coverage stability score, operator matching score and user preference score to obtain the network priority.

[0055] Exemplarily, historical connection score = (signal strength weight × signal strength score) + (signal quality weight × signal quality score) + (network delay weight × network delay score) + (network speed weight × network speed score) + (packet loss rate weight × packet loss rate score) + (traffic cost weight × traffic cost score), wherein the signal strength score is positively correlated with signal strength; the signal quality score is positively correlated with signal quality; the network delay score is negatively correlated with network delay; the network speed score is positively correlated with network speed; the packet loss rate is negatively correlated with the packet loss rate score; and the traffic cost is negatively correlated with the traffic cost score.

[0056] Specifically, the coverage stability score is used to characterize the network's stable coverage capability on the section "from the current geographic location to the destination on the current driving route", and the coverage stability score is positively correlated with coverage stability.

[0057] Specifically, for a current FPLMN, if it belongs to the current SIM card operator, the operator matching score is positive, otherwise the operator matching score is 0.

[0058] Specifically, the user preference score is positively correlated with the user preference degree.

[0059] It can be understood that by determining the network priority of non-emergency call networks in the current FPLMN list based on historical network connection data and current situation data, the network priority can be comprehensively evaluated from multiple dimensions so that the vehicle can give priority to trying the better current FPLMN for network stationing, which is conducive to improving the vehicle's enjoyment of the best network experience.

[0060] In another example, the method further includes: receiving the current FPLMN list of other vehicles and basic information of the vehicle broadcast by other vehicles, or receiving the target FPLMN of other vehicles and basic information of the vehicle broadcast by other vehicles. At this time, S1212 includes: determining the on-site priority of the non-emergency call network in the current FPLMN list of the own vehicle based on historical network connection data, current situation data, and the current FPLMN list (or target FPLMN) of other vehicles and basic information of the vehicle.

[0061] Exemplarily, after S12125, the on-network priority of the non-emergency call network in the current FPLMN list is updated according to the following priority update strategy: for the non-emergency call network in the current FPLMN list of the own vehicle: the on-network priority of the non-emergency call network not included in the "current FPLMN list of other vehicles with the same basic information as the own vehicle" is higher than the on-network priority of the non-emergency call network included in the "current FPLMN list of other vehicles with the same basic information as the own vehicle"; or, the on-network priority of the "target FPLMN of other vehicles with the same basic information as the own vehicle" is higher than the on-network priority of other non-emergency call networks.

[0062] In another example, S1212 includes: inputting historical network connection data and current situation data of the non-emergency call network in the current FPLMN into the trained priority assessment model, and obtaining the on-network priority of the non-emergency call network in the current FPLMN output by the priority assessment model.

[0063] S122. Station the current FPLMNs in the current FPLMN list in sequence according to the stationing priority until a second preset condition is satisfied, wherein the second preset condition includes at least one of the following: the vehicle successfully stations at the target FPLMN or stationing fails for all current FPLMNs in the current FPLMN list.

[0064] It can be understood that by stationing on the current FPLMN in the current FPLMN list in sequence according to the stationing priority, stationing can be attempted in an orderly manner, increasing the probability of finding an available network. Even if some networks are unavailable, there is still a chance to connect to other available networks, thereby improving the success rate of stationing.

[0065] Of course, in other embodiments, stationing is performed on at least one current FPLMN in the current FPLMN list, including: stationing the current FPLMNs in the current FPLMN list in ascending or descending order according to the order in which the current FPLMNs are added to the current FPLMN list until the second preset condition is met.

[0066] S130: When the vehicle successfully camps on at least one target FPLMN in the current FPLMN, the target FPLMN is deleted from the current FPLMN list.

[0067] Specifically, the target FPLMN refers to the current FPLMN where the vehicle is successfully stationed. The vehicle successfully being stationed at the target FPLMN indicates that the target FPLMN is currently an available network. At this point, it needs to be deleted from the current FPLMN list to update the current FPLMN list.

[0068] The disclosed embodiments can locally and automatically update the current FPLMN list in a timely manner, without requiring the user to update the FPLMN list through tedious manual operations or to wait a long time for the FPLMN list to automatically expire, thereby improving the convenience and timeliness of FPLMN list updates.

[0069] In another embodiment of the present disclosure, after deleting the target FPLMN from the current FPLMN list, it also includes: broadcasting the updated current FPLMN list and basic information of the vehicle, or broadcasting the target FPLMN list and basic information of the vehicle, wherein the basic information includes at least one of the following: vehicle series, vehicle model and current SIM card operator.

[0070] Specifically, the current FPLMN list (or target FPLMN) and basic information of the vehicle may be broadcasted via a broadcasting method known to those skilled in the art, such as Bluetooth broadcasting, and the present disclosure does not limit this.

[0071] It can be understood that by broadcasting the current FPLMN list and the basic information of the vehicle or broadcasting the target FPLMN and the basic information of the vehicle, vehicles with the same basic information in the surrounding area can also give priority to trying the target FPLMN, thereby improving the success rate of other vehicles stationed in the network, reducing the risk of other vehicles constantly trying to station in the network resulting in a long stationing time, and thus reducing roaming switching delays.

[0072] In another embodiment of the present disclosure, when the vehicle successfully camps on a target FPLMN in at least one current FPLMN, network registration is performed for the target FPLMN.

[0073] Specifically, once a vehicle has successfully stationed on a network, it must then register with the network to legally initiate and receive communications on that network. Network registration involves the vehicle sending a request to the selected network to verify its identity and obtain service authorization. If registration is successful, the network will allow the device to use its resources and services. Simply put, stationing focuses more on how to select and connect to a network, while network registration is a subsequent step involving the formal registration and authentication process on the selected network to ensure that it can properly use that network's services.

[0074] It is understandable that after the current FPLMN list is successfully updated, network re-registration needs to be triggered immediately to avoid registration failure due to residual invalid FPLMNs.

[0075] The following describes in detail the method for local updating of FPLMN provided by the embodiment of the present disclosure with reference to a specific example. Figure 2As shown, (1) Detect FPLMN list: T-BOX detects its stored FPLMN list every time it is powered on (regardless of whether the vehicle has a network or not, it needs to be checked. If the vehicle has a network, it must not affect the network in use). (2) Determine FPLMN status: For each FPLMN in the FPLMN list, it should regularly try to stay on the network so that when the vehicle network quality is less than the preset threshold or the network is disconnected, it can switch to a better network. Among them, the order of trying to stay on the network is as follows: emergency call network is tried first. If there are multiple emergency call networks in the FPLMN list, the order of trying to stay on the network is as follows: private network / 5G slice>cellular network (5G / 4G)>satellite communication>WIFI, ensuring that the network related to Ecall / Bcall gets the first chance to be retried; then try non-contracted roaming operators or FPLMNs with poor signal quality. These FPLMNs can determine the order of trying to stay on the network based on factors such as current geographical location, current driving route, historical network connection data, current SIM card operator, user preferences, etc. (3) Clear available FPLMNs: If TBOX can successfully register to a certain FPLMN, the FPLMN is cleared from the FPLMN list. At the same time, the localized FPLMN list, as well as its own vehicle series, model, operator information and other information can be packaged and broadcasted, so that other vehicles with the same conditions in the surrounding area can give priority to trying the above-mentioned cleared available FPLMNs, avoiding other vehicles from searching for networks one by one and reducing roaming switching delays. For example: Vehicle A is paired with Vehicle B via Bluetooth, and then a Bluetooth data channel (such as SPP / RFCOMM) is established. Vehicle A can then package the localized FPLMN list, as well as its own vehicle series, model, operator information and other information and send them to Vehicle B. (4) Update FPLMN list: After TBOX successfully clears the available FPLMNs, it must immediately trigger network re-registration to avoid registration failure due to residual invalid FPLMNs. After the T-BOX is successfully updated, it must continue to monitor the status of other FPLMNs.

[0076] Figure 3 FIG. 1 is a structural diagram of a device for locally updating FPLMN provided by an embodiment of the present disclosure.
