Personalized card writing method, system and device

Abstract

The invention discloses a personalized card writing method and system. The method comprises: a subscriber logs in a remote card writing server via a card writing terminal; the remote card writing server distributes personalized data and card writing components required by the subscriber to an intermediate card connected with the card writing terminal, and the intermediate card stores the personalized data and the card writing components; and the intermediate card is connected to a subscriber terminal used by the subscriber, and the subscriber terminal reads the personalized data in the intermediate card, and calls the card writing components in the intermediate card to write the personalized data to a subscriber identity module (SIM) or a universal subscriber identity module (USIM) in the subscriber terminal. The invention simultaneously discloses the remote card writing server, a subscriber card and the user terminal. By adopting the method, system and device provided by the invention, the safety of the service data can be ensured, the realization is simple and convenient, and the service experience of subscribers can be enhanced.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a personalization card writing method, system and device. Background technique [0002] The personalized card writing service is a service of writing personalized data into a subscriber identity card (SIM, Subscriber Identity Module) or a global subscriber identity card (USIM, Universal Subscriber Identity Module). The personalization data specifically refers to the network parameters and personal data related to the user number in the SIM card or USIM card (usually, the SIM card is used in the 2G network, and the USIM card is used in the 3G network), that is, it is used for the user to log in to the network normally, Normal use of mobile service data. [0003] At present, there are mainly two ways to realize the personalized card writing business: [0004] 1) Remote card writing [0005] Remote card writing is a business that establishes a card writing terminal in the busine...

Problems solved by technology

[0006] But, there can be certain problem in this scheme in practical application: described card write terminal is usually slightly modified, such as the ordinary personal computer (PC, PersonalCumputer) that remote card write control program is installed, and those skilled in the art know, The security of existing PCs cannot be fully guaranteed, that is to say, the card writing component saved on the PC is likely to be attacked and maliciously cracked, which in turn leads to security risks in the SIM card.

However, this scheme also has certain defects, such as: it is necessary to develop a special card writing terminal and a main card, which is different from the program 1) that only needs to install a remote card writing program on an ordinary PC, and the special card writing terminal used in this scheme, etc. It is more complicated to implement, and in the process of writing cards, short messages or GRPS channels need to be used for business data interaction, which is slow and has a low sending success rate, thus reducing the user's business experience
