Embodiment

[0025] Such as image 3 As shown, the mobile communication terminal of this example includes a first radio frequency front end, a second radio frequency front end, a first switch, a baseband processor, a second switch, a first mobile phone card interface, a second mobile phone card interface, and other functions unit and power system. Into the first mobile phone card interface and the second mobile phone card interface, insert two mobile phone cards respectively corresponding to the working modes of the first radio frequency front end and the second radio frequency front end. Under the control of the baseband processor, when the first switch connects the first radio frequency front-end to the baseband processor, and the second switch connects the first mobile phone card to the baseband processor, the mobile communication terminal in this example can complete the first mobile phone System functions; when the first switch connects the second radio frequency front-end to the bas...

Abstract

The invention relates to a mobile communication technology, especially a mobile communication terminal with a plurality of standby modes. Aiming to solve the problems of high cost and low sensitivity caused by the intra-influence of two systems of double-card mobile phone in prior art, the invention discloses a mobile communication terminal based on the microscope by turns standby mode, which can realize dual-card dual-standby phone, dual-mode dual-standby phone or single card standby function. The technical solution in the invention comprises: switching the mobile phone card and radio frequency front by a high speed change-over switch, to cause the two systems to work on different time slot, and forms microscope standby 'by turns', thereby avoids the intra-interference. Base-band processor selects switch conduction mode automatically according to the mobile phone card class used by the user, to realize the simultaneous standby of dual cards in same mode or different modes. Applying the invention in dual-card mobile phone, can reduce cost, and avoid intra-interference between the two systems.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a mobile communication terminal with multiple standby modes. Background technique [0002] The rapid development of communication technology, as well as the continuous improvement of users' demand for communication quality and communication information, have formed a situation where multiple modes of mobile communication systems coexist today, such as the second-generation GSM and CDMA mobile communication systems, the third-generation CDMA2000, W -CDMA and TD-SCDMA mobile communication systems. These mobile communication systems use different radio frequency bands, the physical layer technology is not compatible, and the charging standards are also different due to geographical reasons. In order to realize simple, fast, and cheap timely and appropriate communication, users need to have mobile communication terminals (or mobile phones) of various standards, which greatly increa...
