Description
Technical field
The present invention relates to mobile communication technology, relate in particular to a kind of portable terminal and stand-by switching method thereof.
Background technology
Along with the continuous development of mobile communication technology, the function of various portable terminals is constantly expanded, and its every performance also improves greatly, makes portable terminal (as mobile phone) become a necessary article of people's live and work gradually.In the daily use of portable terminal, the portable terminal that initial single deck tape-recorder list is treated can not satisfy some users' demand, particularly business users, often need switch between two or more cards.And if the portable terminal that the user uses the single deck tape-recorder list to treat, must shut down and unload the switching that battery just can block, then Ka frequent switching must bring a lot of troubles for the user, influences operating efficiency, therefore, the portable terminal of double-card dual-standby more and more is subjected to user's favor.
The portable terminal of double-card dual-standby of the prior art mainly is divided into two kinds, and a kind of is to support two global system for mobile communicationss (Global System for Mobile Communication simultaneously; Hereinafter to be referred as: the GSM) subscriber identification module of network (Subscriber Identity Model; Hereinafter to be referred as: the SIM) portable terminal of card standby, the i.e. portable terminal of the two standbies of the two GSM of support; A kind of is SIM card and code division multiple access (Code-Division Multiple Access who supports a GSM network simultaneously; Hereinafter to be referred as: the CDMA) subscriber identification module of network (User Identity Model; Hereinafter to be referred as: the UIM) portable terminal of card standby, promptly support the portable terminal of double-module double-standby.For the portable terminal of supporting two SIM card standbies simultaneously, can be divided into two types of dual-card dual-standby dual-pass and dual-card dual-standby single-pass.The former is by two baseband processor (Baseband Processor; Hereinafter to be referred as: BP) realize two card standbies simultaneously and conversation simultaneously, as Fig. 1 is the hardware configuration schematic diagram of dual-card dual-standby dual-pass portable terminal in the prior art, as shown in Figure 1, this portable terminal comprises that a main BP and one are from BP, each BP connects a draw-in groove respectively, and promptly every card all has corresponding BP to come its information is handled.And the portable terminal of dual-card dual-standby single-pass is realized the standby of two card by the time-division multiplex technology on a BP, as Fig. 2 is the hardware configuration schematic diagram of dual-card dual-standby single-pass portable terminal in the prior art, as shown in Figure 2, this portable terminal includes only a BP, this BP is connected with two draw-in grooves, realize a BP simultaneously to the processing of two cards by time-division multiplex technology, promptly every card is all realized the interaction process of information by this BP.And for the portable terminal of supporting SIM card and the standby of UIM card simultaneously, because the portable terminal of this double-module double-standby need be supported the network of two kinds of standards simultaneously, therefore can not realize by a multiplexing BP, can only be at an application processor (Application Processer; Hereinafter to be referred as: AP) go up two BP of carry and realize.As Fig. 3 is the hardware configuration schematic diagram of double-mode double-standby mobile terminal in the prior art, as shown in Figure 3, this portable terminal comprises an AP and two BP, each BP goes up the corresponding draw-in groove that connects, the type difference of two BP, be respectively GSM baseband chip and CDMA baseband chip, can realize that therefore the UIM that supports the SIM card of GSM network and support cdma network is stuck in standby simultaneously on the terminal.Yet portable terminal of the prior art can only be supported two standbies of two GSM or double-module double-standby, can not support two standbies of two GSM and double-module double-standby simultaneously, can not meet consumers' demand.
