Description
Technical field
The utility model relates to technical field of wireless terminals, relates in particular to a kind of wireless terminal and plurality of SIM cards jockey thereof.
Background technology
SIM card (Subscriber Identity Module, Subscriber Identity Module) is used on wireless terminal user identity and Service Privileges being authenticated, and wireless terminal is by setting up alternately and being connected and finishing communication function of map network with Subscriber Identity Module.In the prior art, the baseband chip of a wireless terminal can only connect a SIM card, that is to say that a wireless terminal can only use a telephone number.
Under the common driving of technology, market and wireless mobile applied business development, the wireless mobile communications industry development is rapid, and mobile communication product has become the necessary article of people's routine work, life.Along with number of mobile phone users constantly increases, it is also more and more that user has the situation of SIM card of two above portable communication apparatus simultaneously.For example some need the crowd of frequent two places work, for avoiding expensive roaming in other places expense, can respectively have the SIM card on anticipatory remark ground usually in two places, use different SIM card in different cities.Frequent replacing SIM card or carry two mobile phones all very the trouble.
Address that need, the portable communication apparatus of a plurality of SIM card has appearred supporting, as controlling and change the data that comprised in two Subscriber Identity Modules, select to use any SIM card by restarting of mobile phone by the little processing and control element (PCE) (MCU) on the utilization mobile phone.This method needn't the user manually be changed the exchange that card just can be realized double SIM card, but need close mobile phone when switching SIM card and restart mobile phone again, and is very inconvenient for the user.
Publication number provides a kind of double card double standby mobile phone for the U.S. Patent application of US2006/0234693A1.This mobile phone can reach the mutual switching of two cards at open state, and does not need shutdown, does not more need manually to change card.But this mobile phone needs two cover baseband chips and two cover radio systems to come corresponding two SIM cards respectively, and the cost rising and the volume of mobile phone are increased.
Along with the demand in technical development and market, the scheme that a baseband chip connects two or more Subscriber Identity Modules has appearred again in the prior art, comprising:
(1) the built-in a plurality of Subscriber Identity Module handover modules of baseband chip.Along with technical development, some baseband chip has realized that by the mode of built-in multi-user's identification card handover module a baseband chip connects a plurality of Subscriber Identity Modules.A kind of cell phone control circuit is provided and has supported the mobile phones that block more as the Chinese patent application of publication number for CN201674672U.Described cell phone control circuit includes baseband module and sheet selected control molding piece.Baseband module includes a plurality of subscriber identify module card controllers, is used for controlling a plurality of subscriber identify module cards that coupled; Sheet selected control molding piece is coupled to baseband module, in order to a plurality of protocol entities to be provided, correspond to a plurality of subscriber identify module card controllers respectively, wherein when one of them protocol entity was set up conversation or data bus connection, protocol entity notified other protocol entities to change into second state by first state.This kind solution integrated level height, it is convenient to manufacture, but its shortcoming is a very flexible, must use specific baseband chip, autgmentability is poor.
(2) increase special-purpose multi-user's identification card handover module.Existing a large amount of baseband chip does not have built-in Subscriber Identity Module handover module, and equally also there is the demand of multi-card multi-standby in the system that uses these baseband chips, in such system, need to increase special chip for this reason and connect plurality of SIM cards, the double card double standby mobile phone of a kind of single cover chip realization is provided for the Chinese patent application of CN101217745A as publication number, described single chip dual-card dual-standby mobile telephone comprises antenna, radio-frequency module, baseband processing module, power module and two sim card slots, described baseband processing module links to each other with an electronic switch that connects two sim card slots simultaneously by the SIM interface, and by sheet selected control system circuit electronic switch is controlled.Thereby on a cover mobile phone hardware, realize the standby simultaneously of two cards.But so special chip can only be supported two-way or three tunnel SIM card at most at present.
Treat demand at wireless terminal four cards four that occur on the market, prior art has following two kinds of solutions:
The first, referring to shown in Figure 1, by baseband chip 1 and two single-chip 2 cascades of supporting the two-way SIM card of built-in two Subscriber Identity Module handover modules, each single-chip 2 links to each other with two SIM cards, thereby realizes four cards, four functions for the treatment of.
The second, referring to shown in Figure 2, by baseband chip 1 ' and three single-chip 2 cascades of supporting the two-way SIM card of no built-in multi-user's identification card handover module, each single-chip 2 links to each other with two SIM cards, thereby realizes four cards, four functions for the treatment of.
But there is following shortcoming in above-mentioned two kinds of schemes:
1) in order to realize four cards, four functions for the treatment of, each single-chip 2 all needs peripheral circuit, thereby scheme shown in Figure 1 need design 2 peripheral circuits, and scheme shown in Figure 2 need design 3 peripheral circuits, thus the peripheral circuit more complicated;
2) when switching in four SIM cards, scheme shown in Figure 1 needs 1 internal command and 2 interface chip orders, and scheme shown in Figure 2 needs 3 interface chip orders, thereby required order is more, has reduced treatment effeciency;
3) scheme shown in Figure 1 needs two single-chips 2, and scheme shown in Figure 2 needs three single-chips, thereby has increased the area of circuit board, has improved production cost; When realizing that four cards four are treated above demand, its needed chip can be more, thereby production cost can further improve.
