Problems solved by technology

[0005] However, when a large number of end users perform upgrade visits, the interaction between the distributed persistence management device and the distributed database may be blocked, which in turn doubles the capacity of multiple ordered queues inside the distributed cache device and leads to memory exhaustion , eventually causing the entire FOTA service to be unavailable, thus affecting the stability of the FOTA upgrade

Embodiment Construction

[0040] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] see figure 1 , propose an embodiment of the stable processing method based on FOTA upgrade of the present invention, described method comprises the following steps:

[0042] Step S11: The stabilization processing device generates a certain number of semaphores during initial startup.

[0043] The stable processing device of the present invention controls the concurrent number of upgrade requests through a semaphore. In this embodiment, the stable processing device includes a stable filter module and a stable monitoring module. When the stable filter module is initially started, the value of the semaphore is calculated according to the memory capacity of the distributed cache device and the size of the data interacted with each time by the FOTA server. number, and generate a corresponding number of semaphores....

Abstract

The invention discloses a stabilizing treatment method and device based on FOTA (Firmware Over-The-Air) upgrading. The method comprises the following steps: a stabilizing treatment device generates a certain quantity of semaphores during initial startup and controls a concurrent quantity of upgrading requests sent to an FOTA server according to the semaphores; the stabilizing treatment device detects the length of each ordered queue in a distributed cache device and calculates the growth rate of the FOTA data according to the length; and the stabilizing treatment device dynamically regulates the quantity of the semaphores according to the growth rate of the FOTA data. Therefore, the real-time monitoring of the upgrading requests of the FOTA server and the dynamic regulation of the concurrent quantity of the upgrading requests can be realized, various strategies are adopted to cause stability and data integrity to be balanced, the stability of the FOTA upgrading is improved, the stability and the smoothness of system operation are guaranteed, the accuracy and the integrity of data in the ordered queues can be furthest guaranteed, and the accuracy of later data analysis and operation is guaranteed.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a stable processing method and device based on FOTA upgrade. Background technique [0002] The FOTA upgrade (Firmware Over-the-Air) technology mainly refers to a technology for remotely managing and updating firmware in a terminal device through an air interface. Through the FOTA upgrade operation, not only the application software can be downloaded and upgraded, but also the operating system of the device can be updated. In this way, the FOTA upgrade operation enables the device manufacturer to send the upgrade package to the user's terminal device through the network, thereby upgrading the firmware and software, which not only facilitates the user, but also saves costs for the device manufacturer. [0003] During the FOTA upgrade process of the existing terminal device, the FOTA server will interact with the terminal device multiple times, and will synchronize a...
