Abstract

The invention discloses a single-chip, multi-card and multi-standby mobile phone. The mobile phone comprises a baseband processing chip and a plurality of card slots for installing a user identification module. A plurality of user identification controllers which are same with the card slots in number are integrated in the baseband processing chip; each user identification controller is connected to one card slot and the constant connection is kept; and one baseband processing controller integrated by the base band processing chip is only connected to one user identification controller at same time. The user identification module comprises an SIM (Subscriber Identity Module) card, a UIM (User Identify Module) card and a USIM (Universal Subscriber Identity Module) card; correspondingly the user identification controllers are an SIM controller, a UIM controller and a USIM controller. The mobile phone has the characteristics of high integration, small size and high reliability during change of multiple cards, and has the advantages of small interference and low noise. The invention further discloses a method for solving conflict of the single-chip, multi-card and multi-solution during reading-writing multiple cards and receiving service. The method has the characteristic of high efficiency and fast speed; and by adopting the method, unnecessary cell reselection operation can be avoided, and power consumption can be reduced.

Description

technical field [0001] The application relates to the field of mobile communication, in particular to a multi-card multi-standby mobile phone realized by a single chip. Background technique [0002] The Chinese invention patent (hereinafter referred to as patent A) with the authorized announcement number CN101217745B discloses a single-chip dual-card dual-standby mobile phone, and its hardware structure is as follows: figure 1 shown. The single-chip dual-card dual-standby mobile phone includes independent modules such as an antenna, a radio frequency module, a baseband processing chip, a power supply, an external storage medium, an electronic switch, and two SIM card slots. Except that there are two SIM card slots, all other modules have only one. There is a SIM interface and a chip selection control circuit in the baseband processing chip. The SIM interface is connected to the electronic switch, and the electronic switch is connected to two SIM card slots at the same tim...
