Simplified transmission and upgrading method for OTA data of Android system and storage medium of simplified transmission and upgrading method

Abstract

The invention provides a simplified transmission and upgrading method for OTA data of an Android system. The method mainly comprises the steps that a sending end preprocesses an OTA data packet, screens repeated files in an OTA data packet and records first information; after leaving at least one sample, each duplicated file discards rest duplicated files and then transmits the duplicated files toa receiving end; the receiving end obtains the processed OTA data packet and finds samples of the repeated files according to records of the first information; according to the OTA data transmissionmethod and the OTA data transmission device, copy samples of the first information are received and filled according to the record of the first information to restore the OTA data packet, so that theOTA data needing to be transmitted are effectively slimmed, the transmission efficiency of the OTA data is improved, the data transmission time consumption and the bandwidth requirement are reduced, and the use experience is greatly improved.

Description

technical field [0001] The invention relates to the technical field of streamlined data transmission, in particular to a streamlined transmission and upgrade method of Android system OTA data and a storage medium thereof. Background technique [0002] The full English name of OTA is Over-the-AirTechnology (space download technology). OTA upgrade refers to the standard software upgrade method provided by the Android system, which remotely manages SIM card data and applications through the air interface of mobile communication (GSM or CDMA). technology. The air interface can use WAP, GPRS, CDMA1X and short message technology. The current application of OTA technology enables mobile communications to provide not only voice and data services, but also new service downloads.

In order to ensure that the system can be restored in the event of abnormal si...

AI Technical Summary

Problems solved by technology

[0003] The existing OTA data transmission scheme is implemented by adding codes on the basis of the existing system firmware. In order to ensure that the system can be restored in the event of abnormal situations such as upgrade failures and power outages, it is necessary to completely download the firmware and replace the original firmware. Upgrade or improvement, so data transmission consumes a lot of bandwidth, and the overall download time is extremely long, resulting in an extreme waste of network resources, which seriously affects the experience of using this type of technology

[0004] On the other hand, with the development of the existing Android system OTA upgrade differential packet technology, the existing technology can already generate a differential packet on the server side according to the version number of the current upgrade end, thereby reducing the amount of data transmission.

However, the problem that the existing technology cannot solve is that the firmware package that is flashed into the device for the first time still needs to be completely downloaded or transmitted. The above effects cannot be achieved when improving or other scenarios that require a complete download of the firmware
