Method for interlocking between machine and card, user identification module card and terminal

Abstract

The embodiments of the invention provide a method for interlocking between a machine and a card, a user identification module card and a terminal, for realizing interlocking between the machine and the card and effectively guaranteeing safety of business. The method for interlocking between the machine and the card comprises the user identification module card receives the identity identification of the terminal and the user identification module card stores at least one identity identification of a legal terminal; the user identification module card is in the stored at least one identity identification of the legal terminal, the user identification module card sends to the terminal the identity identification of the user identification module card when the user identification module card has the same received identity identification, so that the terminal can confirm the user identification module card is the legal user identification module card according to the user identification. The invention can be used in mobile communication business.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for machine-card interlocking, a subscriber identification module card and a terminal. Background technique [0002] At present, with the development of communication services and the continuous improvement of user needs, communication operators have launched a machine-card binding service with relatively preferential tariffs for business promotion needs. This machine-card binding service requires the terminal and the subscriber identification module card to be used together, and the user needs to use a dedicated terminal and a dedicated subscriber identification module card bound to each other. To realize this kind of machine-card binding service, firstly, it is required that the special subscriber identification module card can only be used on the special terminal bound with it, and cannot be used on ordinary terminals. Security also requires that the dedicated...

Problems solved by technology

[0004] But above-mentioned two kinds of methods of prior art can only realize single lock card, all can not realize machine-card interlock (Phone and Card Mutual Lock), promptly can only make special-purpose user identity module card only in its binding It is used on dedicated terminals, but there is no restriction on dedicated terminals. Any subscriber identification module card can be used in dedicated terminals. Therefore, the legitimate rights and interests of operators and the security of machine-card binding services cannot be effectively guaranteed.
