Embodiment Construction

[0076] Embodiments of the present application are described below in conjunction with the accompanying drawings.

[0077] The embodiments of the present application can be applied to a scenario where the first device downloads a data package when it is in normal use, or a scenario where a full image upgrade package needs to be downloaded for repair when the first device cannot be used normally. For example, when the mobile phone mirroring causes the mobile phone to fail to boot or boot normally due to reasons such as flashing, random access memory (random access memory, RAM) jump, read-only memory (read-only memory) jump, third-party application mistakenly deleted files, etc. When using it, you need to download the full image upgrade package for repair. It should be understood that, when the first device cannot be used normally, the operating system currently used by the first device is a backup operating system. Although the function of the backup operating system is relative...

Abstract

A method and device for downloading data packets, the method comprising: a first device sends a first request message to x second devices respectively, and sends a second request message to N-x second devices respectively; the first device receives N pieces of capability information from N second devices; the first device determines a fragmentation strategy based on the N pieces of capability information; the first device sends corresponding fragmentation download request messages to the M second devices based on the fragmentation strategy; The first device receives M data packet fragments from M second devices. Therefore, the first device can utilize the idle capabilities of the M second devices to realize fast downloading of data packets, which can effectively shorten the downloading time of data packets.

Description

technical field [0001] The present application relates to the field of terminals, in particular to a method and device for downloading data packages. Background technique [0002] At present, in the field of over-the-air (OTA) technology, the device side issues a system upgrade application or the server side pushes a system upgrade request, and the device side decides whether to upgrade the system to the latest version. If it chooses to upgrade, it will establish a transmission with the server. Link to download the latest upgrade package. [0003] However, as each updated system version carries more and more new functions, the size of the upgrade package becomes larger and larger as the version changes, and is often calculated in GB. Therefore, the time for downloading the upgrade package occupies an absolute part of the upgrade time. most of the time. Although the strategy of downloading the upgrade package in the background can be adopted when the device is in normal use...
