Mobile terminal and system upgrade method thereof

Abstract

The invention discloses a mobile terminal, which is applied to dual-channel-based communication. The mobile terminal comprises a first mobile communication system and a second mobile communication system which is connected with the first mobile communication system through a universal serial bus, wherein the first mobile communication system is used for sending an upgrade instruction to the second mobile communication system during acquisition of an upgrade package; the second mobile communication system is used for receiving the upgrade instruction and sharing a storage region to the first mobile communication system according to the upgrade instruction; the first mobile communication system is also used for receiving the storage region, and sharing the upgrade package to the second mobile communication system through the storage region; and the second mobile communication system is also used for receiving the upgrade package, and performing upgrading according to the upgrade package. The invention also discloses a system upgrade method. Through adoption of the mobile terminal and the system upgrade method, the problem of upgrade of a dual-card terminal using a 4G network is solved.

Description

technical field

[0001] The invention relates to the field of communication technology, in particular to a mobile terminal and a system upgrading method thereof. Background technique

[0002] Currently on the market, mobile terminals that can be configured with dual SIM cards (SubscribeIdentityModule, customer identification module) usually can only support one card for surfing the Internet and the other card for making calls, and there are very few mobile terminals that can simultaneously support two SIM cards for surfing the Internet. With the development of mobile communication technology, some mobile terminals have realized that two cards can access the Internet at the same time, but if one card is connected to the 4G network, the other card can only connect to the 3G network at most. The ability to connect to the 4G network at the same time with dual cards. Moreover, there is currently no method to upgrade the systems corresponding to the two SIM cards, especially the u...
