A multi-card one-phone radio mobile phone and its implementation method

Abstract

The invention relates to radio mobile phone technology, in particular to a multi-card wireless mobile phone in one machine and a method for realizing the simultaneous use of multiple cards in one machine. A multi-card wireless mobile phone, which includes at least two telephone decks, and also includes baseband processors with the same number as the telephone decks and a selection switch; the telephone decks are electrically connected to the corresponding baseband processors; At least two baseband processors are electrically connected to the common radio transceiver through selection switches, and communicate with corresponding serving base stations through antennas. Mobile phone user can use the mobile phone of the present invention that can install at least two cards under a kind of technology standard according to actual needs, also can dispose the mobile phone that has multiple technology standard (GSM, CDMA20001X etc.) card at the same time, has realized one machine many The function of multiple card numbers, and the at least two card numbers can be used at the same time, fundamentally overcome the defects of the prior art.

Description

[technical field]

[0001] The invention relates to radio mobile phone technology, in particular to a multi-card wireless mobile phone in one machine and a method for realizing the simultaneous use of multiple cards in one machine. [Background technique]

[0002] Currently there are two main standards applicable to 2G wireless devices: one is GSM / GPRS / EDGE, and the other is CDMA20001X. The GSM standard defines that mobile phones use SIM cards to work, while CDMA20001X defines that mobile phones use RUIM cards. In addition, emerging WCDMA, EVDO, TD-SCDMA and other 3G standards and future mobile phone standards also use cards of their corresponding technical standards. These mobile phone cards are all detachable, and the user's unique mobile phone number and personal information are stored thereon. That is: most of the existing mobile phones are one machine, one card and one number. With the busy business of people from all walks of life, or wishing to separate the phone call...
