4 Business frame
Adopting many application frame of GP ,the whole frame of near field communication business has installed many applications in SIM/UIM card. It is separated by several independent safe region, so this can guarantee the seclusion of each other and the independence. Each application can offer the safe region ,application and application data respectively..
Whole frame of near field communication business need to fulfill the norm which is established by the Global Platform. It contains three parts: card delivered man, application provided man and user

4.1 Card delivered man
Taking the responsibility of delivering and managing card, card delivered men own card management system, key management system and certificate management system equipment which can be only used in the dissymmetrical situation. They can administer the card’s resource and lifecycle ,key, and certificate, they can also administer the foundation of safe region which is offered by other supporters ，and the
popedom of administer ,and then can exchange the application data with the other safe region. They are often operator, for example China Unicom.

4.2 Application provided man
Offering and administering the application of near field communication business, providing with application management system, key management system, certificate management system equipment which is offered in the dissymmetrical situation, application provided men supply all kinds of business application and administer the card’s safe region. They can also control the application key of safe region,
certificate, data and so on. Meanwhile the function of safe download would be included. They could be operator, bank, public transport
company and retailer.

4.3 User
  Taking charge of download ,install and use the near field communication business ,user can  offer all kinds of business application through card delivered men and application provided men exchanged mutually, operating the mobile platform and SIM/UIM card, downloading in the safe region and installing new application.

5 Business system constitute

5.1 User card

(1) support SWP protocol
  Making use of the C6 pin which is not be used in the SIM card until now to SWP communication, connecting the C6 pin which is not be used with the near field communication chip, user card can assure the communication between near field communication and user card so this can support contactless exchange, contemporarily it must be compatible with ISO7816 in order to ensure the norm using of original mobile
communication business.
     　　
（2）Support multithreading operating mode
  Multi near field communication business can be used by the user ,so this need multi application be in activate situation synchronously。Therefore ,the whole frame of SIM card must support multithreading  or multi operating.

（3）Support GP frame
In order to ensure the safety of exchange application and download in the air, the frame of application management should be achieved following the Global Platform 2.1.1.

（4）Support Jave standard
In order that the industry application provided men and the trusty third party can explore exchange application, user card can support Java standard to assure the operation between card and application. Javacard 2.2.1 needed to support too.

（5）Support BIP function
In order that operator can supply with more diversification dynamics service and ensure the high velocity of data transfer, mobile platform and contactless user card should fulfill the supporting of BIP function.
