Embodiment 1

[0042] combined with figure 1 As shown, an OTA upgrade download method based on layered interaction design, including:

[0043]The first layer of interaction: the interaction between the smart terminal and the upgrade management server:

[0044] After the smart terminal is turned on and connected to the network, it carries the information of the smart terminal device and sends an upgrade request to the upgrade management server;

[0045] The upgrade management server is based on whether the smart terminal device information matches the deployed upgrade plan. If there is a matching upgrade plan, it will send an upgrade request response message carrying the download address of the upgrade policy file to the smart terminal. If there is no match, it will reply to the smart terminal with ERROR status information . Initiates a second-tier interaction only if there is an upgrade deployment.

[0046] The second layer of interaction: the smart terminal interacts with the upgrade pol...

Embodiment 2

[0056] On the basis of Example 1, in conjunction with the attached figure 1 and 2 As shown, the upgrade management server responds to the upgrade request of the smart terminal and the process of the smart terminal downloading the upgrade policy file to the upgrade policy server is as follows:

[0057] The smart terminal receives the upgrade request response message from the upgrade management server. When the upgrade request response message is empty or in the ERROR state, jump directly to step C7; when the upgrade request response message is not empty and not in the ERROR state, the smart terminal parses the upgrade request response message, Obtain the upgrade deployment version number, upgrade strategy download address and md5 code, and compare the upgrade deployment version number with the firmware version number in the machine. If the upgrade deployment version number is higher than the firmware version number of the machine, go to step C1, otherwise Go to step C7;

Embodiment 3

[0066] On the basis of Example 1, in conjunction with the attached figure 1 and 2 As shown in , the current upgrade deployment version number sversion of the server is added to the upgrade request response message of the upgrade management server, as shown in Table 1.

[0067]

[0068] Table 1 Fields added to the upgrade request response message

[0069] The fields associated with the upgrade policy file in the upgrade request response message are shown in Table 2,

[0070]

[0071]

[0072] Table 2 Fields related to the upgrade policy file in the upgrade request response message

[0073] The upgrade pre-decision in the first-layer interaction includes: first parse out the upgrade deployment version number in the upgrade request response message, compare the upgrade deployment version number with the local firmware version number, and when the upgrade deployment version number is higher than the local firmware version No., analyze the upgrade policy file download a...

Abstract

The invention discloses an OTA upgrade download method based on a hierarchical interaction design. The method comprises an intelligent terminal and an upgrade management server, an upgrade strategy server and an upgrade package server, and comprises the following steps: first-layer interaction: sending an upgrade request to the upgrade management server by the intelligent terminal, matching equipment information of the intelligent terminal with a deployed upgrade plan, returning an upgrade request response message by the upgrade management server, and performing upgrade pre-decision by the intelligent terminal; second-layer interaction: downloading an upgrade strategy file by the intelligent terminal from the upgrade strategy server, and parsing the upgrade strategy file to obtain a download address of a file needing to be downloaded; and third-layer interaction: downloading an upgrade package by the intelligent terminal from the upgrade package server, and saving the upgrade package in a cache partition. According to the OTA upgrade download method based on the hierarchical interaction design provided by the invention, a hierarchical interaction process of an intelligent terminalupgrade application and a cloud server is adopted, upgrade decision processing is added in each layer of interactive nodes, the operation of downloading files of the intelligent terminal is reduced byoptimizing the interaction, and the upgrade judgment and downloading efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of operating system software, in particular to an OTA upgrade download method based on layered interaction design. Background technique [0002] In addition to the solidified system software on the Android smart terminal when it leaves the factory, the device manufacturer is still continuously updating the whole machine software to solve the legacy problems of the old version and add new functions to improve the user experience. Upgrading the system software on the user device through OTA is an efficient method commonly used by many Android smart terminal device manufacturers. Some Android smart terminal manufacturers rent the OTA service platform provided by other companies, and some manufacturers build their own OTA upgrade systems, but these OTA upgrade systems are all composed of cloud upgrade servers and smart terminal device upgrade applications. The device requests an upgrade from the cloud server an...
