Embodiment Construction

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and 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.

[0021] The present invention provides a method for standby switching of the SIM card of a mobile terminal, please refer to figure 1 , the method flow includes:

[0022] S110, monitor the signal strength of each SIM card of the mobile terminal in real time;

[0023] S120. Determine whether there is a first SIM card that satisfies the call forwarding condition. The call forwarding condition is that the signal strength of the SIM card is lower than a preset threshold. If there is the first SIM card, perform step S130;

[0024] S130. Determine whether the f...

Abstract

The invention discloses an SIM (subscriber identity module) standby switchover method and a device of a mobile terminal and belongs to the technical field of communication. The method comprises the steps of monitoring signal strength of each SIM of the mobile terminal in real time, judging whether a first SIM meeting a call forwarding condition exists, judging whether the first SIM meets a condition of enabling a call forwarding function if so, and enabling the call forwarding function of the first SIM if so, wherein the call forwarding condition is that the signal strength of the SIM is less than a preset threshold, and the condition of enabling the call forwarding function is that the duration that the signal strength of the first SIM is less than the preset threshold exceeds a first preset duration. With the adoption of the method and the device, the problem of call missing due to a poor signal of dual SIM dual standby can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and a device for standby switching of a SIM card of a mobile terminal. Background technique [0002] With the rapid development of science and technology, people's lives are becoming more and more abundant. The complex relationship network between people has already broken through the limitations of time and space. Now smart terminals have also begun to add However, due to the limitation of the chip, before the ideal goal of transitioning from dual card and single pass to dual card and dual pass, single pass has always been the resistance that hinders the development of dual card function. [0003] The existing dual-card terminal can insert two subscriber identity modules (Subscriber Identity Module, SIM), and can simultaneously answer calls on standby, but due to the limitation of chip functions in the prior art, two SIM cards cannot simultaneously select multiple...
