A telecom intelligent card, an air card writing system and an air card writing method

Abstract

The invention provides a telecom intelligent card, an air card writing system and an air card writing method. The telecom intelligent card pre-writes KI numbers and is provided with an IMSI number input module which is used for inputting IMSI numbers of the intelligent card, and also an individualized data writing module which receives and writes individualized data of the intelligent card. The card writing method includes the following steps: users send numbers needed to be opened and ID numbers of blank telecom intelligent cards to a server through a client service; the server obtains individualized data with IMSI numbers after testing the numbers to pre-open numbers and send the IMSI numbers to the client device; users install the blank telecom intelligent card to a mobile phone and input the IMSI numbers; the sever sends the individualized data to the blank telecom intelligent card which writes the individualized data. The card, card writing system and method can realize the air card writing in remote areas; the running and maintenance cost of the card writing system is lower, thus being good for the popularization and application of the air card writing system.

Description

technical field [0001] The invention relates to a telecommunication smart card, in particular to a telecommunication smart card based on short message writing, an air card writing system and an air card writing method for writing to the telecommunication smart card. Background technique [0002] Along with the development of mobile communication technology, the use of mobile phone is very popular, and mobile phone mostly uses detachable telecommunication smart card to carry out communication, as SIM card, UIM card etc. There are many kinds of data stored in the existing SIM card, including system original data written by the SIM card manufacturer, personalized data such as network parameters and user data written by the telecom operator when it is sold to the user. [0003] The SIM card manufacturer will hand over the blank SIM card with the original data of the system to the telecom operator, and when selling the SIM card to the user, use the remote card writing system to m...

AI Technical Summary

Problems solved by technology

[0011] Although the card writing system can realize remote card writing and improve the work efficiency of handling SIM card account opening, the card writing system needs to be equipped with a remote card writing device, and the operation and maintenance costs of the card writing system are relatively high.

Moreover, the card writing device and the server need to be connected through a wired network. For remote areas where there is no wired network, the card writing system cannot be used for remote card writing, which is not conducive to the promotion and application of the card writing system.
