Description
Technical field
The present invention relates to communication technical field, particularly relate to the wireless communication technology field that terminal is used subscriber identification card SIM.
Background technology
At present, wireless communication technique is showing improvement or progress day by day, and its business model is also constantly weeded out the old and bring forth the new.Such as the business model of a kind of existing " machine card integrated ", the band machine is machine card integrated when networking, and its mainly realization means are to replace traditional mobile phone card SIM with terminal recognition sign indicating number PSID sign indicating number, and the PSID sign indicating number is write in the mobile phone.That is to say, the PSID sign indicating number be distributors in the identification code of before sales at the common carrier place, be used for and phone number binding is used.
For this type of new business pattern, under the driving of common carrier subsidy policy, some illegal businessman utilize the technological means of " separation between machine and card " to seek exorbitant profit, promptly carry out the operation that mobile phone separates with cell-phone number in bulk, mobile phone after separating is sold to other market with low price, and will separate and other users are given in the SIM card direct marketing that obtains, therefrom seek exorbitant profit.These illegal businessman's the normal market order of way serious impact causes a large amount of telephone expenses to run off, disturb normal price policy, and the mobile phone charge of operator is sustained a loss; Seriously impact simultaneously manufacturer terminal market.
In view of above situation, common carrier and SIM supplier and manufacturer terminal have been taked various solutions from hardware and the encryption of software aspect, attempt to stop the realization of illegal " separation between machine and card " technology.Described solution roughly can be divided into two kinds of special-shaped card scheme and encrypted cards.So-called " special-shaped card " is meant by the means of pin (internal circuit) or the change SIM physical form of hardware modifications SIM, makes it to put into regular handset and use.SIM after being modified becomes non-standard card, therefore is referred to as " special-shaped card " in the industry.Encrypted card then refers to adopt the mode of software to realize, promptly by the means of encrypting the internal information of SIM is encrypted, and the mobile phone that only has secret key could normally read the information on the SIM and carry out proper communication.
Yet, by the checking of practice, above-mentioned prior art scheme not only causes the rising of terminal fault rate, the inconvenience of maintenance, simultaneously owing to crack the continuous appearance of means, make encrypted card and special-shaped card itself lose due effect, cause occurring SIM by free call on sb. else's expense through illegal means and mobile phone by the phenomenon of hollow pin.
Summary of the invention
