Embodiment Construction

[0044]In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0045] Aiming at the current dual-card dual-standby mobile terminal on the market, it only provides automatic switching for the 2G / 3G / 4G network of the same operator, but when facing different operators, it can only rely on the user to manually switch the network. The solution provided by the example is: when the dual-card dual-standby mobile terminal moves to a place where the network quality of the default network type is poor, the mobile terminal can automatically mark the USIM card of the high-quality operator as the default communication card, thereby saving Remove t...

Abstract

The embodiment of the invention provides a network switching method and a mobile terminal. The method comprises: a universal subscriber identity module card corresponding to the better marked network quality in the marked network quality corresponding to at least two target network types marked in an area where a mobile terminal is located is determined; the determined universal subscriber identity module card corresponding to the better marked network quality is compared with a universal subscriber identity module card in current default usage by the mobile terminal to determine whether two universal subscriber identity module cards are same; if not, the universal subscriber identity module card in current default usage by the mobile terminal is switched to be the determined universal subscriber identity module card corresponding to the better marked network quality. Therefore, the universal subscriber identity module (USIM) card of the operator with the excellent network quality can be marked as a default USIM card automatically, so that the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a network switching method and a mobile terminal. Background technique [0002] As we all know, the call quality and data communication of mobile terminals are closely related to the network quality provided by telecom operators. Because the network quality of various telecom operators varies in different regions, for example, in some regions, the signal of China Mobile is relatively weak, while the signal of China Unicom is relatively strong. The network provided by the operator can make up for the defect that the operator has different network quality in different regions. When a dual-card dual-standby mobile terminal makes a mobile call in a fixed area, if a USIM card (Universal Subscriber Identity Module: Universal Subscriber Identity Module) with poor network quality is used to make a mobile call, the mobile terminal needs radio frequency transmission power to ...
