Abstract

The invention provides a method, a device and a terminal for card personalization over the air. The method comprises the following steps of: transmitting an integrated circuit card identity (ICCID) of a subscriber identity module (SIM) card to an authentication device for the card personalization over the air, so that the authentication device for the card personalization over the air authenticates the SIM card according to the ICCID; receiving a random parameter from the authentication device for the card personalization over the air after the SIM card passes the authentication, wherein the random parameter is generated according to an international mobile subscriber identification (IMSI) number; resolving the random parameter, and acquiring the IMSI number; and writing the IMSI number into the SIM card. According to the method, the device and the terminal for the card personalization over the air, the waste of IMSI number resources can be avoided.

Description

technical field

[0001] The invention relates to communication technology, in particular to a method, device and terminal for writing cards in the air. Background technique

[0002] With the rapid development of mobile communications, more and more users use mobile phones, which makes the resources of various global universal numbers corresponding to SIM cards increasingly tight.

[0003] Especially for the IMSI (International Mobile Subscriber Identification Number) number in the SIM (Subscriber Identity Module, subscriber identification card) card, in the prior art, it has been written into the SIM card when it is produced. stuck. However, it takes a long time for the SIM card to be used from the factory to the sale, which makes the IMSI number occupied all the time. Especially when some users no longer use the SIM card, it takes a long time for the operator to The IMSI number in the SIM card can be taken back and used again, which causes a waste of IMSI number resources....
