Method and device for achieving dual-card dual-standby dual communication of mobile terminal

Abstract

The invention relates to a method and device for achieving dual-card dual-standby dual communication of a mobile terminal. The method includes the steps that a base band-radio frequency interface is shared to establish two radio frequency channels; the two radio frequency channels are switched cyclically in a preset period through a switch switching module, and thus dual-card dual-standby dual communication of the mobile terminal is carried out. According to the method and device, on a platform using one base band and two sets of radio frequency and sharing the base band-radio frequency inference, the switch switching module is added to the radio frequency-base band interface, and thus radio frequency modules of the two paths of independent radio frequency channels can respectively be used cyclically, base band resources are released, it is avoided that one path of radio frequency channel monopolizes the radio frequency-base band interface, and the dual-card dual-standby dual communication of a mobile phone is achieved. Not only is the utilization rate of the base band resources improved, but also the user experience and the practicality of the dual-card mobile phone are improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and a device for realizing dual-card dual-standby and dual-communication of a mobile terminal. Background technique [0002] With the continuous development of wireless communication technology, mobile phones have become an indispensable auxiliary tool for people's daily work, life and entertainment in today's society. With the introduction of different standards of operators, and the impact of various factors such as tariffs, Internet access, separation of work and private life, more and more people have two or more mobile phone cards. For this reason, the user usually needs to carry two or even more than two mobile phones, which brings great inconvenience. [0003] In order to solve the above problems, dual-card dual-standby mobile phones came into being. In order to realize the function of dual card dual standby, there is currently a solution: use one b...

Problems solved by technology

[0004] However, the existing solutions also have deficiencies. Because only one baseband chip is used, and the two radio frequencies share the baseband-radio frequency interface, the mobile phone cannot accept the call requests from the two card base stations at the same time.

When one of the cards is in a call, because it monopolizes the baseband-radio frequency interface, the channel of the other card is completely cut off, and dual communication cannot be achieved, resulting in the user missing the call and affecting the use of the user
