Problems solved by technology

In this way, on the one hand, the integration level of the mobile phone is not high, and the volume is large, which is not conducive to carrying; on the other hand, the cost of the mobile phone remains high, the cost increases, and the power consumption also increases greatly.
For radio frequency signals, in order to avoid co-channel interference, one RF antenna is generally designed at the top of the mobile phone, and the other is designed at the end of the mobile phone to minimize interference, and the distance between the two antennas must generally be greater than 100mm, causing mobile phone The degree of integration and volume are limited

Embodiment Construction

[0019] As mentioned in the background art, the cost of existing dual-card dual-standby mobile phones is relatively high, and some users sometimes even have three or more frequently used SIM cards at the same time. The invention proposes a new mobile terminal and a communication network connection method, which can realize the multi-card standby function under the premise of low cost.

[0020] The specific implementation of the method for connecting a mobile terminal and a communication network provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Please refer to figure 1 , is a schematic structural diagram of the mobile terminal.

[0022] The mobile terminal includes more than two SIM card slots. In this specific embodiment, the mobile terminal includes three SIM card slots, which are card slots 111 , 112 and 113 .

[0023] In other specific embodiments of the present invention, the number of the SIM card ...

Abstract

The invention discloses a mobile terminal and a communication network connection method. The mobile terminal comprises more than two SIM card slots, a micro-control chip which includes a bus module and an SIM card communication module, and an analogue switch chip which is respectively connected with the bus module and the SIM card communication module of the micro-control chip; and the analogue switch chip is also used for realizing electrical connection between the SIM card communication module and one SIM card slot. The mobile terminal and the communication network connection method can be used for realizing low-cost multi-card multi-standby.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for connecting a mobile terminal and a communication network. Background technique [0002] With the improvement of people's daily life, more and more people need to use two or more phone numbers, but generally a mobile phone can only hold a phone card, and it is very difficult for people to carry two or more mobile phones. It is inconvenient, therefore, a dual-card dual-standby mobile phone with dual numbers in one machine has emerged as the times require. [0003] However, current dual-card dual-standby mobile phones usually use two sets of chip architectures, that is, two sets of radio frequency, baseband, and protocol stack software are required, which is equivalent to making the internal chip architectures of two mobile phones in one mobile phone. In this way, on the one hand, the integration degree of the mobile phone is not high, and the volume is large, which...
