Problems solved by technology

However, since the dual-card dual-standby terminal needs to be provided with space for placing two SIM cards, the volume of the dual-card dual-standby terminal will be relatively large during circuit design, which is not convenient for users to carry, and the production cost is relatively high.
[0003] The prior art also provides a terminal with one card and two numbers, which can store two numbers on one SIM card. Although the volume of the terminal is reduced, the terminal with one card and two numbers cannot realize the simultaneous standby of two numbers

Abstract

The invention provides a communication terminal and a standby implementation method thereof and relates to the technical field of communication. The communication terminal comprises a fixing device for placing a storage unit, a baseband processing circuit, a radio frequency circuit and an antenna. The baseband processing circuit is connected with the fixing device and used for obtaining N authentication information in M authentication information. The radio frequency circuit is connected with the baseband processing circuit and used for modulating the authentication information corresponding to N numbers obtained by the baseband processing circuit into high frequency signals and enabling authentication determination information of base stations corresponding to the N numbers or communication signals to be modulated into baseband signals. The antenna is connected with the radio frequency circuit and used for enabling high frequency signals corresponding to the authentication information corresponding to the N numbers to be radiated into space and picking up the authentication determination information of the corresponding base stations from the N numbers in the space. The communication terminal and the standby implementation method of the communication terminal achieve simultaneous standby of a plurality of numbers and reduces the size of the communication terminal.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication terminal and a standby implementation method thereof. Background technique [0002] At present, the dual-card dual-standby terminal is usually equipped with two SIM card slots, so as to realize the simultaneous standby of the two SIM cards, and the user can conveniently choose to use the number corresponding to any one of the SIM cards for communication. However, since the dual-card dual-standby terminal requires space for placing two SIM cards, the volume of the dual-card dual-standby terminal will be relatively large during circuit design, which is not convenient for users to carry, and the production cost is high. [0003] The prior art also provides a terminal with one card and two numbers, which can store two numbers on one SIM card. Although the volume of the terminal is reduced, the terminal with one card and two numbers cannot realize the sim...
