Embodiment Construction

[0019] figure 1 It is a schematic flow chart of a method for writing a smart card according to an embodiment of the present invention. The method in this embodiment can be executed by a server, such as figure 1 Shown, including:

[0020] 101. When a card writing request for instructing a smart card to write a card is received, obtain an idle personalized data card resource, and obtain an idle personalized data code number resource.

[0021] Among them, the smart card is a blank smart card before writing the card, only the hardware identification number is pre-stored, and it can also include a pre-built chip operating system (COS) and card writing application.

[0022] Among them, the personal data card resources include ICCID, KI, operator variable algorithm configuration field (OperatorVariant Algorithm Configuration Field, OP), PIN and PUK; personal data code number resources include IMSI and SMSC.

[0023] When receiving a card writing request for instructing a smart card to write a...

Abstract

The invention provides a smart card writing method and a smart card writing device. When a card writing request used for indicating the writing of a smart card is received, idle personalized data card resources are acquired, idle personalized data code number resources are acquired, and the personalized data card resources and the personalized data code number resources are sent to a terminal loaded with the smart card so as to enable the terminal to write the smart card according to the personalized data card resources and the personalized data code number resources. The idle personalized data card resources and the idle personalized data code number resources are acquired separately when the card writing request is received, so that pre-writing of the personalized data card resources into the smart card is avoided, pre-establishment of the corresponding relation between the personalized data card resources and the personalized data code number resources is avoided, and the technical problem that the utilization rate of the personalized data card resources and the personalized data code number resources is low is solved.

Description

Technical field [0001] The present invention relates to communication technology, in particular to a method and device for writing a smart card. Background technique [0002] Smart card writing refers to writing data necessary for communication into a smart subscriber identity module (Subscriber Identity Module, SIM) card. The current card writing method is to apply to the server to download the personalized data code resource of the smart card through the card writing terminal in the business hall, such as International Mobile Subscriber Identification Number (IMSI) and Short Message Service Center (Short Message Service Center). , SMSC) to write the personalized data code number resource into the smart card through the card writing terminal. [0003] In the prior art, the smart card has pre-written personalized data card resources, including integrated circuit card identity (ICCID), authentication key (Key identifier, KI), and personal identification code (Personal identificatio...
