Abstract

The handset SIM card with two groups of network data includes base board and two network data memory units, one set on one side of the base board and the other set on other side. The handset SIM card in novel structure makes it possible for the user to accept the service from two communication service suppliers simultaneously. The handset SIM card has the same sizes as traditional ones and is easy to match with various cellphones.

Description

Handset SIM card with two groups of network data

The present invention relates to the handset SIM card technique, specifically is a kind of handset SIM card with two groups of network data.

At present, cell-phone (being mobile phone) has become the communication instrument that the modern society people generally use.Interrelated data shows that the social owning amount of China's mobile phone in 2000 has reached more than 4,000 ten thousand, and China will become the potential market of global mobile phone maximum, can reach more than 1.2 hundred million in several years.

Cell-phone mainly is divided into two kinds of digital type and matching tests, and existing pan-European formula GSM hand-phone system promptly belongs to the cell-phone of digital type.When using this cell-phone to carry out communication, cell-phone stores up the record data via reading SIM card, after obtaining network registration in hand-phone system operator's the network, can use in its communication network and dial and connect session services.Yet, the communication channel that numerous system operator is used also is not quite similar, GSM900, GSM1800, GSM1900 etc. are for example arranged, and many operators release service functions such as convenience, liveliness proof, financeization constantly, the cell-phone user will have the SIM card of two or many different system operator different channels simultaneously, is used for selective system operator type service disaggregatedly.

At present, the SIM card that system operator provides for the cellphone subscriber as shown in Figure 1, this SIM card only can be stored group network data, different system operator's network data or same system operator's heterogeneous networks data then need be stored in respectively in the different SIM card.For example when the specific service of needs, just must the selective system operator, replace the exclusive SIM card of this Internet business merchant and use.Because the SIM card volume is little, not portable, preservation, loses easily, loses etc., depositing the SIM card that is replaced has increased inconvenience to the user.

In order to satisfy above-mentioned mobile telephone with multiple cards user's needs, prior art generally adopts two independently SIM card, with two independently SIM card place the corresponding position of battery of mobile phone or mobile phone main body to be provided with in two SIM embedding slot seats, select needed SIM card and mobile phone to connect by conversion control circuit, a diverter switch.Adopt this mode, increased conversion control circuit, the structural member of mobile phone and battery needs redesign, and new die sinking tool increases cost.

The objective of the invention is to overcome the above-mentioned deficiency of prior art, a kind of handset SIM card with two groups of network data is provided, use double SIM card to obtain the demand for services of the different channel that the operator provides to satisfy the cellphone subscriber, do not increase the cost of cell-phone simultaneously again.

The handset SIM card that the present invention has two groups of network data is the innovative product of existing single SIM card.It comprises: substrate and the network data memory that is arranged at the substrate one side, it is characterized in that: the another side at described substrate is provided with second network data memory.

Above-mentioned two network data memories with handset SIM card of two groups of network data store up the network data that record has two numbers of same communication system respectively.

Above-mentioned two network data memories with handset SIM card of two groups of network data store up the network data that record has two numbers of different communication systems respectively.

The SIM card of the network data that will use during use is packed into according to the method for SIM card commonly used in the sim card slot of cell-phone, and start can be used required network service.When needs altering system service provider, only need shut down, take off battery pack, take out this SIM card, and turn-over puts into draw-in groove, the contact of corresponding network data memory is contacted with the draw-in groove contact, load onto battery, start can be used required system service merchant's Communications service.

The present invention has following advantage compared with the prior art: can be chosen at random by the user needs to use a memory of SIM card to be connected to cell-phone, serves disaggregatedly to obtain corresponding system operator.Simultaneously, can avoid system line busy or enter the communication inconvenience that causes the blind area.

This SIM card one card for multiple uses, system conversion is convenient, fast, can enjoy Communications service and the service-specific that two operators of system are provided at any time.

This SIM card overall dimension is identical with legacy card, and is supporting with existing various mobile phones easily, need not redesign the structural member of mobile phone, do not increase the cost of existing mobile phone, accepted by numerous cellphone subscribers easily.

SIM card description of drawings of the present invention is as follows:
