Embodiment 1
[0029] This embodiment provides a method for over-the-air card writing, which is applicable to network architectures including 2G networks and 3G networks. The 2G network is the Global System of Mobile communication (GSM), which includes base stations, MSC (Mobile Switching Center, Mobile Switching Center) and Home Location Register (Home Location Register, HLR). The core, which controls the business of all base stations, provides switching functions and connections with other functions in the system, and the home location register is used to authenticate the ICCID (Integrate Circuit Card Identity) number of the user's SIM card. When the authentication is passed, a random parameter is randomly sent to the SIM card, and the user obtains the IMSI number according to the random parameter. The 3G network includes a base station, MSC and HSS (Home Subscriber Server). The functions of the MSC in 3G are the same as those of the MSC in 2G, and the functions of HSS are the same as thos...
Embodiment 2
[0044] This embodiment provides a method for over-the-air card writing. The network architecture and execution subject applicable to the method for over-the-air card writing are the same as those in Embodiment 1, and will not be repeated here.
[0045] Specifically, the method for over-the-air card writing of this embodiment includes:
[0046] Step 201, judging whether there is an IMSI number in the SIM card, and turning to step 202 when the judging result is no.
[0047] When it is determined that the IMSI number does not exist in the SIM card, it means that the SIM card has not been connected to the network normally before. This is because the network architecture in the prior art requires that the SIM card must have an IMSI number before it can be used normally. No IMSI number means that the terminal using the SIM card can only call emergency numbers, but cannot dial or surf the Internet normally.
[0048] Step 202, send the ICCID number of the SIM card to the authenticat...
Embodiment 3
[0063] Embodiment 3 provides a method for over-the-air card writing, which is used to provide an IMSI number to a terminal without an IMSI number. The applicable network architecture is the same as that described in Embodiment 1, and will not be repeated here. The executor of this embodiment is an authentication device for an over-the-air card, and the authentication device for an over-the-air card may be the authentication device for an over-the-air card described in any of the above-mentioned embodiments.
[0064] Such as figure 2 As shown, it is a schematic flow chart of the method for over-the-air card writing according to this embodiment, which specifically includes:
[0065] Step 301, receiving the ICCID number of the SIM card sent by the terminal, and authenticating the SIM card according to the ICCID number.
[0066] The ICCID number is an integrated circuit card identification code in the prior art, which is solidified in the SIM card. ICCID numbers can be compose...
