Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present invention in its various embodiments. However, the technical solution claimed in the present invention can be implemented without these technical details and various changes and modifications based on the following embodiments.
As shown in fig. 1, a first embodiment of the present invention relates to an APP background keep-alive method, which is applied to iOS devices, including but not limited to smart phones and palm computers. The iOS device is in communication connection with a terminal device, such as a vehicle-mounted Bluetooth device. The method includes steps 101 to 105.
Step 101: and receiving a wake-up notice periodically sent by the terminal equipment to wake up the target APP.
In this embodiment, the target APP is, for example, a bluetooth digital key. in the iOS device, the APP that exits the background is generally suspended in about 10 seconds, and different models and running states may affect the suspending time of the APP. For the same model, the APP hang time may vary from 5S (seconds) to 10S (seconds) in different operating states.
Before the iOS equipment and the terminal equipment are connected without establishing Bluetooth, the target APP can be opened, the iOS equipment continuously scans the terminal equipment, and after the scanning is successful, the Bluetooth connection is established with the terminal equipment. Or the iOS device sends a broadcast packet, which is scanned by the terminal device, thereby establishing a connection. After the bluetooth connection is successfully established, the terminal device periodically sends a wakeup notification to the iOS device, and the iOS device executes a wakeup application operation to wake up the target APP after receiving the wakeup notification each time. Specifically, if the target APP is suspended when the wakeup notification is received, the target APP is automatically woken up, the survival time of the target APP in the background after being woken up is recalculated, and if the target APP survives when the wakeup notification is received, the survival time of the target APP after the wakeup operation is executed is also recalculated. Therefore, the iOS device side can keep the target APP alive in the background by periodically performing the wake-up operation.
Step 102: and monitoring survival condition information of the target APP.
Survival status information for APP includes: survival status information of the target APP within the monitoring period; the monitoring time period comprises N current sending periods; n is a natural number greater than or equal to 1.
In this embodiment, the monitoring period is, for example, 1 current transmission cycle. In some examples, the monitoring period may be a plurality of transmission cycles, for example, the monitoring period may include 2 or 3 transmission cycles.
Step 103: and determining whether the sending period of the current awakening notification needs to be adjusted or not according to the survival condition information, executing the step 104 when the adjustment is needed, and returning to the step 101 if the adjustment is not needed.
Step 104: the adjustment direction is determined based on the survival status information.
Step 105: and informing the terminal equipment to adjust the sending period according to the adjusting direction.
In this embodiment, steps 103 and 104 specifically include: and determining whether the target APP is suspended in the monitoring time period according to the survival condition information in the monitoring time period, and if the target APP is suspended in the monitoring time period, determining that the sending period needs to be adjusted and the sending period needs to be reduced.
In this embodiment, the information on the survival status in the monitoring period includes: monitoring the survival time of the target APP in each sending period in a time period; the survival time of the target APP in each sending period in the monitoring time period is obtained by monitoring in the following mode:
controlling a timer to start timing when a current awakening notification is received, acquiring the timing duration of the timer when the next awakening notification is received, and taking the acquired timing duration as the survival duration of the target APP in each sending period; wherein the timer stops counting time when the target APP is suspended.
Here, a counter may be provided in the target APP, and the timing function is realized by counting. When the current wake-up notification is received, the counter is set to 0, and then the counter value is incremented by 1 per unit time, which may be 1 second, 500 milliseconds, 200 milliseconds, etc. And when the next awakening notification is received, reading the count value of the counter, and calculating the timing duration in the current sending period according to the count value and the unit time, wherein the timing duration is the survival duration of the target APP in the current sending period.
Determining whether the target APP is suspended in the monitoring time period according to the survival condition information in the monitoring time period, specifically including: and if the survival time of the APP in one or more sending periods in the monitoring time period is less than the current sending period, judging that the target APP is suspended in the monitoring time period. Specifically, if the monitoring time period is a current sending period, if the survival duration of the APP in the current sending period is less than the current sending period, determining that the target APP is suspended in the monitoring time period; and if the monitoring time period comprises a plurality of current sending cycles, determining that the target APP is suspended in the monitoring time period when the survival time of the APP in any sending cycle in the monitoring time period is less than the current sending cycle.
It should be noted that, in this embodiment, if it is determined that the transmission cycle needs to be reduced according to the survival time of the APP in each transmission cycle in the monitoring time period, the reduction amplitude of the current transmission cycle may be determined according to the survival time of the target APP in each transmission cycle in the monitoring time period, and the reduction amplitude is sent to the terminal device.
Specifically, the reduction amplitude may be equal to a difference between the current transmission period and the survival time of the corresponding APP, for example, if the current transmission period is 8S, the survival time of the corresponding APP is 7.5S, the reduction amplitude may be equal to 0.5S, and the transmission period after adjustment is the survival time of the APP at this time. Alternatively, the amplitude of the adjustment may be increased appropriately, that is, the adjusted transmission period is slightly smaller than the survival time of the APP.
In some examples, monitoring survival status information over a time period may further include: and monitoring whether the network long connection between the target APP and the background server is disconnected in each sending period in a time period. Similarly, if there is a record of disconnection between the target APP and the network long connection of the background server in any sending period in the monitoring time period, it is determined that the target APP is suspended in the monitoring time period.
In some examples, it may also be determined whether a suspension condition of the target APP in the monitoring period meets a preset condition according to the survival condition information in the monitoring period, and if the suspension condition meets the preset condition, it is determined that the transmission cycle needs to be adjusted, and the transmission cycle needs to be reduced. Specifically, if the difference between the survival time lengths of the APP and the current transmission cycle in one or more transmission cycles in the monitoring time period is greater than a first threshold, it is determined that the suspension condition satisfies the preset condition. For example, the first threshold is, for example, 0.5S, if the monitoring time period is a current sending period, the current sending period is, for example, 9S, and the survival time duration in the monitoring time period is 8.8S, at this time, the difference between the current sending period and the corresponding survival time duration is 0.2S, and since 0.2S is less than 0.5S, it is determined that the suspension condition does not satisfy the preset condition, and it is determined that the sending period does not need to be adjusted. In other words, when the difference between the current sending period and the corresponding survival time is small, the sending period may not be adjusted, and when the difference between the current sending period and the corresponding survival time is large, the terminal device is notified to execute the sending period adjustment action, so that the sending period can be prevented from being adjusted frequently without affecting the user experience.
Or, if the survival condition information includes a record of whether the network long connection between the target APP and the background server is disconnected in each sending period in the monitoring time period, and the monitoring time period includes a plurality of current sending periods, the number of times of suspension in the current monitoring time period can also be obtained, and if the number of times of suspension is greater than a set threshold, it is determined that the suspension condition meets a preset condition, and the sending period needs to be reduced.
In this embodiment, the information on the survival status of the APP further includes: system resource usage information related to the actual lifetime of the APP. The system resource usage information is, for example, system resource usage. In particular, the system resource usage may be a combined usage of system resources related to the lifetime of the application, such as a combined usage of processor and memory resources, or a usage of a single system resource.
The actual lifetime of the APP may vary with the usage of system resources. In step 103 and step 104, if the target APP is not suspended within the monitoring time period or the suspension condition of the target APP within the monitoring time period does not satisfy the preset condition, it indicates that the current transmission cycle has satisfied the APP keep-alive requirement, but the transmission cycle may need to be increased along with the change of the APP survival time, and at this time, a corresponding estimated survival time is obtained according to the system resource usage information and the preset corresponding relationship between the estimated survival time and the system resource usage information; and if the difference between the estimated survival time and the current sending period is larger than a second threshold value, determining to increase the sending period.
The correspondence between the estimated time to live and the system resource usage information is, for example, the correspondence between the estimated time to live interval and the system resource usage interval. For example, the system resource usage rate is between 80% and 90% when the survival time is between 5S and 6S. For example, the second threshold is 1S, if the current transmission period is 5S, and the estimated survival time obtained according to the system resource usage information and the preset corresponding relationship between the estimated survival time and the system resource usage information is, for example, 6.5S, it may be determined that the difference between the estimated survival time and the current transmission period is greater than the second threshold, and at this time, it is determined that the transmission period needs to be increased.
It should be noted that, in some examples, the present embodiment may further include: and if the system resource use change rate is determined to be in the preset change range according to the system resource use information, the terminal equipment is notified to adjust the sending period in a suspending mode until the system resource use change rate deviates from the preset change range. The system resource usage change rate reflects the fluctuation speed of the system resource usage rate, and also relates to the fluctuation speed of the APP survival time. The preset variation range is used for reflecting the condition that the utilization rate of the system resources fluctuates rapidly. For example, when a user uses an application with large resource consumption, the usage rate of the system resource may fluctuate rapidly. In this embodiment, when the change rate of the system resource usage is within the preset change range, the APP has a fast fluctuation of the survival time, and the terminal device is notified to adjust the transmission period in a suspension manner until the change rate of the system resource usage deviates from the preset change range, and the transmission period adjustment function is resumed. It should be noted that, during the time of suspending the notification of the terminal device to adjust the transmission period, the terminal device may be notified to adjust the transmission period to a smaller value to implement APP keep-alive. Therefore, the embodiment can avoid adjusting the sending period when the survival time of the APP fluctuates fast, thereby reducing the adjusting times of the sending period and being beneficial to reducing the power consumption.
Compared with the prior art, the method has the advantages that the target APP is awakened by the iOS device according to the awakening notification periodically sent by the terminal device, the survival condition of the APP is monitored in real time, whether the sending period of the awakening notification needs to be increased or decreased is determined according to the survival condition of the APP, the sending period is increased or decreased by the terminal device, the sending period is matched with the survival condition of the APP, the APP can be kept alive, the unnecessary awakening notification is reduced, and the power consumption of the device is saved.
The second embodiment of the invention relates to an APP background keep-alive method, which is applied to terminal equipment in communication connection with iOS equipment, wherein the terminal equipment comprises but is not limited to vehicle-mounted Bluetooth equipment. iOS devices include, but are not limited to, smart phones, palm top computers, and the like. The target APP is, for example, a bluetooth digital key. As shown in fig. 2, the method includes steps 201 to 203.
Step 201: a wake up notification to wake up the target APP is periodically sent to the iOS device.
Step 202: in response to a transmission cycle adjustment request transmitted by the iOS device, the transmission cycle is adjusted based on the adjustment direction indicated by the adjustment request.
In this embodiment, if the actual survival time or the estimated survival time of the target APP is received, the sending period is adjusted according to the actual survival time or the estimated survival time.
Here, when the adjustment direction indicated by the adjustment request is to reduce the transmission period, the i OS device may obtain the survival duration (i.e., the actual survival duration) of the APP in the current transmission period according to the method in the foregoing embodiment, and send the survival duration to the terminal device. In step 202, if the actual survival time of the APP sent by the iOS is received, the actual survival time may be used as the adjusted sending period, or the actual survival time reduced by a certain value may be used as the adjusted sending period, so that the sending period may be adjusted in one step. When the adjustment direction indicated by the adjustment request is to increase the transmission period, the iOS device may obtain the estimated survival duration of the APP in the current transmission period according to the method in the foregoing embodiment, and send the estimated survival duration to the terminal device. The terminal device may use the estimated survival time period as the adjusted transmission period.
In some examples, if the actual survival time or the estimated survival time of the target APP is not received, the transmission period is gradually adjusted according to a fixed step size or a step size from large to small.
For example, when the iOS device instructs the terminal device to turn down or turn up the transmission period, the terminal device may adjust the transmission period according to a fixed step size, where the fixed step size is, for example, 0.5S, 0.2S, and the like. In some examples, the terminal device may gradually adjust the transmission period in a step-wise manner from a large step size to a small step size. For example, when the sending period is reduced, the initial step length may be 1S, that is, the sending period is reduced by 1S to obtain the adjusted sending period, and with the increase of the adjustment times, the step length may be reduced to 0.5S or 0.2S, etc., so that not only the sending period can be adjusted quickly, but also the adjusted sending period can be made to be closer to the actual survival time of the APP, thereby achieving the balance of application keep-alive and energy consumption saving.
Step 203: and sending a wakeup notification according to the adjusted sending period.
After the adjustment of the transmission period is completed, the terminal device may notify the iOS device, and transmit a wakeup notification according to the adjusted transmission period.
Compared with the prior art, the embodiment periodically sends the awakening notification to the iOS device, and adjusts the sending period according to the indication of the iOS device, so that the APP keeps alive, the sending of the awakening notification is reduced as much as possible, and the energy consumption of the device is saved.
