Description

Technical Field

[0001] This application relates to the field of vehicle-mounted vehicle technology, and in particular to a network connection method, device, equipment, medium, and product. Background Technology

[0002] With the rapid development of automotive intelligence, in-vehicle network systems have become an indispensable part of modern automobiles. These systems support various intelligent vehicle functions, such as navigation, remote control, and fault diagnosis. However, ensuring the stability and reliability of in-vehicle network systems when the vehicle is in sleep mode remains a significant technical challenge for the industry.

[0003] In the standard approach, the vehicle enters a sleep mode after the user locks and leaves the vehicle to conserve energy and extend battery life. While in sleep mode, the vehicle maintains a fixed heartbeat cycle to keep connected to the cloud. Each heartbeat wakes the vehicle, which then interacts with the cloud to confirm the status of the persistent connection. If the interaction is successful, the connection is considered normal; if it fails, the vehicle attempts to re-establish the connection with the cloud.

[0004] However, in practical applications, due to the instability of the network environment, this simple reconnection mechanism may encounter the situation of long connection being broken again during the reconnection process, which is not conducive to the stability of long connection. Summary of the Invention

The heartbeat wake-up information is used to indicate the connection status between the vehicle and the cloud, and the paging reception information is used to indicate the paging status of the cell accessed by the vehicle.

[0008] If the heartbeat wake-up information indicates a connection anomaly between the vehicle and the cloud, and the paging reception information indicates an anomaly in the paging process of the cell the vehicle is accessing, then if the network quality of the first cell meets preset conditions, the cell the vehicle is accessing will be switched from the second cell to the first cell, and the first cell will be a neighboring cell of the second cell.

[0009] Secondly, embodiments of this application provide a network connection device, the device comprising:

[0010] The first acquisition module is used to acquire heartbeat wake-up information and paging reception information corresponding to the heartbeat cycle when the vehicle is in a heartbeat cycle.

[0011] The switching module is used to switch the cell accessed by the vehicle from the second cell to the first cell when the heartbeat wake-up information indicates that there is a connection abnormality between the vehicle and the cloud, and the paging reception information indicates that there is an abnormality in the paging process of the cell accessed by the vehicle. If the network quality of the first cell meets the preset conditions, the first cell is a neighboring cell of the second cell.

[0021] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0022] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0023] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the term "comprising" or any other variations thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0024] To address the problems of the prior art, embodiments of this application provide a network connection method, apparatus, device, medium, and product.

[0025] The network connection method provided in the embodiments of this application is described below.

[0026] Figure 1 A flowchart illustrating a network connection method according to an embodiment of this application is shown. Figure 1 As shown, the method may specifically include the following steps:

[0027] Step 101: When the vehicle is in a heartbeat cycle, obtain the heartbeat wake-up information and paging reception information corresponding to the heartbeat cycle;

[0028] Step 102: If the heartbeat wake-up information indicates a connection anomaly between the vehicle and the cloud, and the paging reception information indicates an anomaly in the paging process of the cell the vehicle is accessing, and if the network quality of the first cell meets preset conditions, then the cell the vehicle is accessing is switched from the second cell to the first cell, and the first cell is a neighboring cell of the second cell.

[0029] In step 101, when the vehicle is in a heartbeat cycle, the heartbeat wake-up information and paging reception information corresponding to the heartbeat cycle are obtained;

[0030] In this embodiment, the heartbeat wake-up information is used to indicate the connection status between the vehicle and the cloud, and the paging reception information is used to indicate the paging status of the cell the vehicle is connected to. When a long-term connection exists between the vehicle and the cloud, the vehicle sends a fixed amount of information to the cloud at regular intervals to ensure the stability of the long-term connection. The heartbeat interval refers to the interval between two messages sent by the vehicle to the cloud. During this heartbeat interval, the vehicle is in a sleep state, and the heartbeat wake-up information refers to the connection information between the vehicle and the cloud during this sleep state. The paging reception information refers to the relevant information of the paging messages received by the vehicle during this sleep state.

[0031] In step 102, if the heartbeat wake-up information indicates a connection anomaly between the vehicle and the cloud, and the paging reception information indicates an anomaly in the paging process of the cell accessed by the vehicle, and if the network quality of the first cell meets preset conditions, then the cell accessed by the vehicle is switched from the second cell to the first cell, and the first cell is a neighboring cell of the second cell.

[0032] In this embodiment, the paging process refers to the process by which the base station locates the vehicle. Only when the connection between the vehicle and the base station is normal can the connection between the vehicle and the cloud be guaranteed to be normal. Therefore, if there is a connection anomaly between the vehicle and the cloud, and an anomaly in the paging process, it is considered that the second cell accessed by the vehicle is abnormal, i.e., the network quality is poor.

[0033] The second cell is the same cell as the first cell's Public Land Mobile Network (PLMN network). Different operators will operate different PLMN networks, and each network has its own unique identifier, called the PLMN ID, which is used to uniquely identify a PLMN in the network.

[0034] The second cell is deemed to meet the preset conditions when its network quality meets the following conditions:

[0035] Within a preset time period, the reference signal received power of the second cell is greater than a first threshold, and the fluctuation of the reference signal received power is less than the second threshold; within the preset time period, the signal-to-noise ratio (SNR) of the second cell is greater than a third threshold, and the fluctuation of the SNR is less than a fourth threshold, wherein the first threshold is greater than the second threshold, and the third threshold is greater than the fourth threshold. As an example, the preset time period can be 10 seconds, the first threshold can be 75 dB, the second threshold can be 3 dB, the third threshold can be 20 dB, and the fourth threshold can be 3 dB.

[0036] Alternatively, multiple second cells can be sorted according to their network quality from high to low to obtain a first cell sequence. When switching from a second cell to a first cell, the second cell is switched to the first cell in descending order according to this first cell sequence.

[0037] In the network connection method provided in this application embodiment, by obtaining the heartbeat wake-up information and paging reception information of the vehicle during the heartbeat cycle, it is possible to determine whether the network of the second cell accessed by the vehicle is abnormal. In this way, if there is a network quality abnormality in the second cell, the vehicle network can be switched to a neighboring cell with better network quality, namely the first cell, which can effectively reduce the risk of connection interruption and realize the stability and reliability of the vehicle network connection.

[0038] In one embodiment of this application, after obtaining the heartbeat wake-up information and paging reception information corresponding to the heartbeat cycle when the vehicle is in a heartbeat cycle, the method further includes:

[0039] If the connection status is disconnected and the reconnection situation is that a reconnection has already occurred, it is determined that there is a connection anomaly between the vehicle and the cloud.

[0040] If the paging message reception rate is less than the preset reception rate, it is determined that there is an anomaly in the paging process of the cell to which the vehicle is connected.

[0041] In this embodiment, the heartbeat wake-up information includes the connection status between the vehicle and the cloud after the heartbeat cycle ends, and the reconnection status between the vehicle and the cloud during the heartbeat cycle. Specifically, the end of the heartbeat cycle means that after the vehicle sends a heartbeat message, if the cloud does not receive the heartbeat message, the connection between the vehicle and the cloud can be determined to be disconnected. If the connection between the vehicle and the cloud is disconnected during the heartbeat cycle, and a reconnection occurs after the disconnection, the cloud will send a notification to the vehicle after the heartbeat cycle ends, informing it that the cloud failed to access the vehicle during the heartbeat cycle, i.e., a reconnection occurred. If the above two conditions are met, it can be determined that there is a connection anomaly between the vehicle and the cloud.

[0042] The paging reception information includes the vehicle's paging message reception rate within a heartbeat cycle. Specifically, this message reception rate can be obtained through the following steps: obtaining the paging cycle of the second cell and the vehicle's first message reception volume within the heartbeat cycle; determining the ratio between the heartbeat cycle and the paging cycle as the second message reception volume; and determining the paging message reception rate by comparing the second message reception volume with the first message reception volume. The preset reception rate can be 90%.

[0043] As an example, if the paging cycle of the second cell is 320ms and the heartbeat cycle is 3200ms, then the second message reception volume is 10 paging packets. If the first message reception volume is 8 paging packets, the paging message reception rate is 80%. If the paging message reception rate is less than 90%, then the paging process of that cell is considered abnormal.

[0044] In this embodiment, the network anomaly of the cell accessed by the vehicle can be determined by the heartbeat wake-up information and the paging message reception rate, thereby improving the accuracy of network judgment for accessing the cell.

[0045] In one embodiment of this application, before obtaining the heartbeat wake-up information and paging reception information corresponding to the heartbeat cycle when the vehicle is in a heartbeat cycle, the method further includes:

[0046] Obtain the vehicle's sleep period, during which the vehicle is in a sleep state;

[0047] A first vehicle control time period is determined within the sleep period. The start time of the first vehicle control time period is the moment when the vehicle first receives a vehicle control message within the sleep period, and the end time is the moment when the vehicle last receives a vehicle control message within the sleep period.

[0048] The step of acquiring heartbeat wake-up information and paging reception information corresponding to the heartbeat cycle when the vehicle is in a heartbeat cycle includes:

[0049] When the vehicle is in the first vehicle control time period and is in a heartbeat cycle, obtain the heartbeat wake-up information and paging reception information corresponding to the heartbeat cycle.

[0050] In this embodiment, in order to ensure network communication between the vehicle and mobile terminals such as mobile phones and tablets while the vehicle is in a dormant state, the present invention can only be triggered when the vehicle is in a dormant state.

[0051] The vehicle's dormancy period refers to the time between when the vehicle is parked and dormant and when mileage is recorded. During the vehicle's dormancy period, there may be information exchange between the vehicle and the mobile terminal, such as the mobile phone controlling the mobile terminal to turn on the air conditioning, lock the doors, or turn on the lights. The time period during which there is message exchange between the vehicle and the mobile terminal is the first vehicle control period. The start time of the first vehicle control period is the moment when the vehicle first receives a vehicle control message during the dormancy period, and the end time is the moment when the vehicle last receives a vehicle control message during the dormancy period.

[0052] To ensure the stability of the network connection between the vehicle and the mobile terminal during the sleep period, heartbeat wake-up information and paging reception information are obtained when the vehicle is in the first vehicle control period, so as to further execute subsequent steps and ensure the stability of the connection.

[0053] In one embodiment of this application, determining the first vehicle control time period within the sleep time period includes:

[0054] The dispersion of the vehicle within multiple second vehicle control time periods in a historical period is obtained, wherein the dispersion is the degree of difference between the multiple second vehicle control time periods;

[0055] Among the plurality of second vehicle control time periods, delete the second vehicle control time periods whose dispersion is greater than a preset threshold to obtain a plurality of third vehicle control time periods;

[0056] The average start time of each third time period in the plurality of third vehicle control time periods is determined as the average start time;

[0057] The average time of the termination time of each of the multiple third vehicle control time periods is determined as the average termination time.

[0058] The time period between the average start time and the average end time is defined as the first vehicle control time period.

[0059] In this embodiment, to ensure that the vehicle can trigger the network connection method of the present invention within a precise time period while maintaining the vehicle's range, it is necessary to obtain the relatively concentrated time periods during the vehicle's daily use to automatically trigger the present invention. As an example, if the period during the sleep period when the vehicle receives vehicle control messages most frequently is between 10:00 and 11:00, then the time period between 10:00 and 11:00 can be determined as the first vehicle control time period.

[0060] Specifically, firstly, all vehicle control time periods within a past period can be acquired. This data may exist in a discrete form, meaning each time period is independent and may be scattered across different time points. The degree of dispersion of each time period can be represented by a dispersion index. Secondly, the collected data is cleaned. Second vehicle control time periods with dispersion exceeding a preset threshold are those that deviate too much from the average time period. Dispersion can be represented by range, average, or standard value. Correspondingly, the preset threshold includes a preset range threshold, a preset average threshold, or a preset standard value threshold. These second vehicle control time periods with dispersion exceeding the preset threshold may be worthless for subsequent analysis and may even mislead the results. Therefore, these abnormal data need to be deleted, leaving a more accurate and reliable dataset, namely the third vehicle control time period.

[0061] Next, the average start time of all third vehicle control time periods is calculated. By taking the average, a representative start time can be obtained, which helps to determine a more stable and representative vehicle control time period later. Similarly, the average end time is obtained.

[0062] Finally, the time period between the average start time and the average end time is determined as the first vehicle control time period. This reveals the time period during which the vehicle frequently receives vehicle control messages. The invention is then executed within this time period, thereby reducing vehicle power consumption.

[0063] In one embodiment of this application, before obtaining the heartbeat wake-up information and paging reception information corresponding to the heartbeat cycle when the vehicle is within the vehicle control time period and in a heartbeat cycle, the method further includes:

[0064] Obtain the parking duration of the vehicle;

[0065] When the vehicle is within the first vehicle control time period and is in a heartbeat cycle, acquiring the heartbeat wake-up information and paging reception information corresponding to the heartbeat cycle includes:

[0066] When the parking duration exceeds a preset duration, the vehicle is within the first vehicle control time period, and is in a heartbeat cycle, the heartbeat wake-up information and paging reception information corresponding to the heartbeat cycle are obtained.

[0067] In this embodiment, the preset duration is preferably 5 minutes. To avoid the vehicle executing the invention during a short period of sleep, this scheme is only activated when the vehicle's parking time exceeds the preset duration, which effectively avoids unnecessary power consumption and improves the vehicle's range.

[0068] In addition, if the vehicle loses connection with the cloud within the heartbeat cycle when the parking time is less than the preset time, it will directly reconnect to the cloud.
