Problems solved by technology

[0002] The current CDMA / GSM dual-mode dual-standby can only realize the simultaneous standby of the domestic CDMA and GSM modes. When roaming to an area covered by GSM only, it can only achieve GSM single-mode standby or dual-GSM standby single-pass mode, and the SIM The card needs to be placed in the correct card slot before it can be used

Embodiment 1

[0032] Such as figure 1 As shown, the present invention provides a dual-mode dual-standby terminal, including: a first dual-mode (CDMA+GSM) baseband chip including a CDMA baseband unit 1 for processing CDMA signals and a GSM baseband unit 2 for processing GSM signals 5. A second dual-mode (CDMA+GSM) baseband chip 7 including a CDMA baseband part 3 and a GSM baseband part 4, an application processor AP chip 6, a first card slot 10 and a second card slot 11 (for placing a SIM card ), the AP chip 6 is connected to the first dual-mode baseband chip 5 and the second dual-mode baseband chip 7 respectively, and the first card slot 10 is respectively connected to the first dual-mode baseband chip 5 and the second dual-mode baseband chip 5 through the quadruple electronic switch 8 The two dual-mode baseband chips 7 are connected, and the second card slot 11 is also connected to the first dual-mode baseband chip 5 and the second dual-mode baseband chip 7 through the quadruple electronic...

Embodiment 2

[0037] Such as figure 2 As shown, the present invention also provides a method for realizing dual-mode dual-standby using the dual-mode dual-standby terminal described in Embodiment 1, including the following steps:

[0038] S1. The first dual-mode baseband chip detects the geographic location of the dual-mode dual-standby terminal;

[0039] S2. The first dual-mode baseband chip detects the type of the SIM card in the first card slot,

[0040] S3. The second dual-mode baseband chip detects the type of the SIM card in the second card slot;

[0041] S4. The AP chip sends the geographic location information detected by the first dual-mode baseband chip to the second dual-mode baseband chip;

[0042] S5. The first dual-mode baseband chip selects the startup mode of the SIM card in the first card slot according to the geographic location information and the type of the SIM card in the first card slot, and the second dual-mode baseband chip selects the startup mode of the SIM car...

Abstract

The invention relates to the technical field of communication and discloses a dual mode and dual standby terminal. The terminal comprises a first dual mode baseband chip, a second dual mode baseband chip, an application processor (AP) chip, a first clamping groove and a second clamping groove. The AP chip, the first clamping groove and the second clamping groove are connected with the first dual mode baseband chip and the second dual mode baseband chip respectively. The invention further discloses a method for achieving dual mode and dual standby. According to the dual mode and dual standby terminal and the method for achieving dual mode and dual standby, dual mode and dual pass standby can be achieved in any area, and two subscriber identity module (SIM) cards can be inserted into any clamping groove to be used in any mode.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a dual-mode, dual-standby terminal and a method for realizing dual-mode, dual-standby, and dual-communication. Background technique [0002] The current CDMA / GSM dual-mode dual-standby can only realize the simultaneous standby of the domestic CDMA and GSM modes. When roaming to an area covered by GSM only, it can only achieve GSM single-mode standby or dual-GSM standby single-pass mode, and the SIM The card needs to be inserted into the correct card slot before it can be used. [0003] Therefore, how to design a solution that can realize dual-mode dual-pass standby in any area and that can be used by inserting dual SIM cards into any card slot is an urgent problem to be solved. Contents of the invention [0004] (1) Technical problems to be solved [0005] The first technical problem to be solved in the present invention is: how to design a scheme that can realize dual...
