Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Usually integrated subscriber identification module on the Plug-in SIM card of today, the user can only have the network ID of a common carrier on a portable terminal, can not satisfy the user has two or more carrier ID in a portable terminal demand, and, can be implemented in shared same portable terminal in the mobile communications network under the different systems along with the development of portable terminal.In order to save the portable terminal inner space also in order to save cost, integrated dual user identification module or user identification module multi will be the most effective settling modes on a Plug-in SIM card, this just need increase PAD quantity on the Plug-in SIM card, the information interface of subscriber identification module is provided.Be that example describes now with encapsulation dual user identification module on the Plug-in SIM card.
Traditional Plug-in SIM card is of a size of 25mm (length) * 15mm (wide) * 0.76mm (thick), contact position and concrete size as shown in Figure 1, the minimum contact size is generally 2mm * 1.7mm.
The mode of two subscriber identification modules of encapsulation can have several modes below (but being not limited only to) on plug-in SIM card base:
● shared identical contact.
At present SIM card is used 5 PAD, according to the position of each contact of ISO7816 standard code as shown in Figure 2, and the signal definition such as the table 1 of each contact.If two common subscriber identification modules of encapsulation can be carried out the signal switching controls by idle contact C4 or C8 between two modules, its chip and contact position can be as shown in Figure 3, and each contact definition is as table 2.Perhaps do not take original contact, by the C9 contact of an arbitrary shape of optional position increase on card, carry out the signal switching controls between two modules, as shown in Figure 4, each contact signal definition is as table 3.
There is annexation mutually in two sim modules that embed the card base, can just be chosen between two modules by the level of control contact C4 (C8) on the module or contact C9 and switch, and for example high level is selected SIM1, low level SIM2.The signal control switching circuit can have multiple multi-form, and this is a known technology.Because common contact, in section at the same time, have only a sim module in running orderly to carry out data communication by interface down, another SIM card is under suspension or the dormant state.When needed, changeable coming.So under synchronization, only support the network of a Mobile Network Operator to connect.

● use diverse contact.
Two subscriber identification modules that embed the card base work alone separately, no annexation, and exterior terminal provides corresponding interface according to the smart card packaged type, and portable terminal need provide two cover contacts.By the control of portable terminal, carry out the selection of sim module, can only select a module job, also can select two modules to work simultaneously.Two modules can be encapsulated on the same one side of card base or on coplanar not.
Two subscriber identification module encapsulation side by side on the same one side of card base, its outside Pad physical form is similar, but because the size restrictions of Plug-in SIM card, the Pad of increase needs corresponding minification, as shown in Figure 5.
Two subscriber identification modules encapsulate at the not coplanar of card base, and its external contact physical form is identical, as shown in Figure 6.A kind of as contact intelligent card of regulation SIM card in GSM11.11 and the ISO/IEC7816 standard, its thickness is 0.78mm.The Chip Packaging of two-sided PAD is removed intermediate insulating layer, and each face has the space greater than 0.35mm thickness, can realize fully that with now packaging technology Fig. 7 can be referring to the xsect effect of its encapsulation.
By with upper type, on a SIM card chip, realize to provide for two or more mobile communication carriers the technical scheme of service.Two SIM chips carry different telecom operators' services respectively; The user no longer needs to change SIM card when changing telecom operators; During physical connection, only adaptive socket gets final product in the simple change of the needs mobile phone.
Method described in the utility model and smart card are not limited to the embodiment described in the embodiment, and those skilled in the art draw other embodiment according to the technical solution of the utility model, belong to technological innovation scope of the present utility model equally.
