Method, system and terminal for system update between mobile communication terminals

Abstract

The embodiments of the present invention provide a method, system and terminal for system update between mobile communication terminals. The method includes the following steps: a destination mobile terminal judges whether it is compatible with a source mobile terminal on hardware; if the two parties are compatible on hardware, the destination mobile terminal obtains system backup files transmitted by the source mobile terminal through a wireless network; and the destination mobile terminal performs system update on the basis of the system backup files. The advantage of the above technical solutions provided by the embodiments of the present invention lies in that the system update can be realized between mobile phones through the wireless network, no longer depends on an update server, and does not need to download update files from the update server, and thereby the burden of the update server can be reduced and meanwhile it is good for the mobile phone users to exchange their systems conveniently. The success rate of the update can be ensured by judging whether the hardware of the two parties is compatible before an update. With the embodiments of the present invention, users are provided with more convenient update means to choose, rather than totally rely on the operator servers or professionals.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, system and terminal for system upgrade between mobile communication terminals. Background technique [0002] figure 1 Schematic diagram of an over-the-air upgrade for prior art. Wireless upgrade is generally through OTA (Over-the-Air Technology, over-the-air technology), which needs to download the upgrade package from the operator's upgrade server to the cache partition of the mobile phone or SD card (Secure Digital Memory Card, secure digital card), and then When starting the installation, the upgrade package should be as small as possible considering the cost of the download process, so the differential method is generally used. However, there are still variables in the OTA upgrade process, which may be undiscovered bugs or power outages during the upgrade. [0003] In the prior art, there is a mature Linux LiveCD (directly bootable system) solution on the PC, su...

Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that the prior art has at least the following deficiencies: the upgrade method of the prior art relies on a professional upgrade server, and the upgrade is not convenient, which is not conducive to exchanging or updating the system between users.

Moreover, the upgrade method of the prior art does not consider whether the system upgrade file to be written into the mobile phone is compatible with the hardware version of the mobile phone, so there is a risk of upgrade failure. Once the upgrade fails, the functions of the mobile phone cannot be used normally. The method also has deficiencies in terms of security
