Communication terminal and user card switching method thereof

Abstract

A communication terminal and a user card switching method thereof, the communication terminal supports at least two user cards, all user cards correspond to at least two network modes, and at least one of all user cards supports two or more network modes The first user card in standby mode; the communication terminal includes each baseband module corresponding to each network mode, and at least one of all baseband modules supports two or more user cards in the network mode corresponding to the baseband module The first baseband module on standby; the communication terminal also includes an application module, and the application module includes a control unit adapted to output a control signal when it is detected that the switching condition is met, and is adapted to communicate with the first baseband module under the control of the control signal A baseband module communicating with a user card is a switching unit for switching between the first baseband module and other baseband modules. The technical scheme can realize smooth switching of user cards, improve network finding efficiency during switching, and reduce impact on normal services.

Description

technical field [0001] The invention relates to the communication field, in particular to a communication terminal and a user card switching method thereof. Background technique [0002] With the rapid development of communication technology, the exchange of information between people is also more frequent, a mobile phone can no longer meet people's needs, especially those engaged in sales, management and other work, sometimes need two or three or more mobile phones to Barely meets needs. And it is very inconvenient to carry so many mobile phones, therefore, multiple cards and multiple standby mobile phones have appeared on the market. This kind of mobile phone allows users to only need one mobile phone carrier, but can install multiple Subscriber Identity Module (SIM, Subscriber Identity Module) cards or global Subscriber Identity Module (USIM, Universal Subscriber Identity Module) cards, which is obviously more convenient than carrying multiple mobile phones a lot.

Problems solved by technology

[0010] The problem to be solved by the present invention is that when the existing multi-card multi-mode communication terminal loses coverage or cannot normally reside in the network where the user card is on standby, it is difficult to realize the standby of the user card in time and reduce power consumption; When the signal quality of the network deteriorates, it is difficult to improve the quality of communication services provided by the user card in time
