Embodiment
Below in conjunction with accompanying drawing, a kind of method of locking of user number by wireless terminal device and embodiment of device of realizing provided by the invention is described in detail.
At first a kind of method of locking of user number by wireless terminal device that realizes that the embodiment of the invention is provided is described in detail.
As shown in Figure 1, a kind of method that realizes locking of user number by wireless terminal device that the embodiment of the invention provides in wireless terminal device energising start, enters before the init state, carries out following steps:
S101, judge whether wireless terminal device has inserted SIM card, if, carry out S102, if not, execution in step S112.
Whether the SIM card that S102, judgement are inserted is the SIM card of test usefulness, if, execution in step S111, otherwise, execution in step S103 continued.
This step S102 is an optional step, this step S102 need and set for the test of SIM card, SIM card is before sale or after selling, may test, the MCC that tests employed SIM card is different with the normal SIM card of using of user in the network with MNC, can judge whether this SIM card belongs to the test SIM card by MCC and MNC in this step to SIM card, if test SIM card, then permit wireless terminal device and be used, this wireless terminal device enters normal initialization procedure subsequently.
S103, judge and whether store encrypted file system in this wireless terminal device that (Encrypting File System, EFS) file if exist, determine that then this wireless terminal device had locked Subscriber Number, execution in step S105; If do not exist, determine that then this wireless terminal device did not lock this Subscriber Number, execution in step S104.
In the embodiment of the invention, the international mobile subscriber identification number (International Mobile Subscribe Identity, mapping value IMSI) and the IMSI of SIM card that comprise mapping value, Subscriber Number and the SIM card of Subscriber Number and wireless terminal device IMEI in the EFS file.
S104, wireless terminal device and Subscriber Number are locked, generate EFS file and storage.Turn to execution in step S111 then.
In embodiments of the present invention, Subscriber Number can be write in advance by operator and distribute to the user in the SIM card, for example Subscriber Number can be write in the MSISDN file of SIM card.
Particularly, in that the process of wireless terminal device and Subscriber Number locking and generation EFS file is as follows:
Read allocating in advance of storing in the SIM card that the current wireless terminal equipment inserts to the Subscriber Number of this wireless terminal device and the IMEI of this wireless terminal device, according to default hash algorithm, calculate the Subscriber Number that reads and read the mapping value between the IMEI and deposit in predefined first logo file;
Read the IMSI of the SIM card that the current wireless terminal equipment inserts,, calculate the mapping value of the Subscriber Number that reads and IMSI and deposit in predefined second logo file according to default hash algorithm;
Write down the IMSI of the SIM card of current insertion, deposit in predefined the 3rd logo file;
It is read-only and the unsuppressible-suppression state that first logo file, first logo file and the 3rd logo file are set.
First logo file, second logo file and the 3rd logo file have been formed the EFS file.
Preferably, in the embodiment of the invention, default hash algorithm can adopt the MD5 hash algorithm.The MD5 hash algorithm belongs to the irreversible encryption algorithm, its ciphering process does not need to use key, form ciphertext to expressly encrypting the back, ciphertext after the encryption can't directly be deciphered, decrypting process must expressly be encrypted once more through input, when relatively the result of twice encryption is consistent, can think that just the plaintext of input once more is the plaintext after the deciphering.It is big that the irreversible encryption algorithm cracks difficulty, and easy to use, do not have the problem of key keeping and distribution.
S105, read the IMEI of wireless terminal device, and store in the SIM card of current insertion allocate Subscriber Number in advance to this wireless terminal device; Calculate first mapping value between the two;
Computational methods adopt default hash algorithm, the hash algorithm that this is default, and the algorithm that adopts with step S104 is identical.
S106, first mapping value that step S105 is calculated are compared with the mapping value of wireless terminal device IMEI with the Subscriber Number that comprises in the EFS file of wireless terminal device storage, if both unanimities, execution in step S107, otherwise, execution in step S112.
Under the situation of both unanimities, the Subscriber Number in the SIM card of current insertion is described, consistent with the Subscriber Number of this wireless terminal device locking.Otherwise, think that Subscriber Number and this wireless terminal device among the SIM of current insertion do not match, forbid the use of this wireless terminal.
The IMSI of S107, reading SIM card, Subscriber Number that calculating is read and second mapping value between the IMSI.
Computational methods adopt default hash algorithm, the hash algorithm that this is default, and the algorithm that adopts with step S104 is identical.
S108, second mapping value that step S107 is calculated are compared with the mapping value of SIM card IMSI with the Subscriber Number that comprises in the EFS file of wireless terminal device storage, if both unanimity, execution in step S111; If both are inconsistent, then carry out following step S109.
In this step S108, under the situation of both unanimities, the SIM card of using when the SIM card of current insertion and this locking of user number by wireless terminal device are described is the same card, if both are inconsistent, there will be two kinds of situations so, the legal card (Subscriber Number does not become, but SIM card is changed) that changes of a kind of user of being, another kind is illegal jack per line card.In order further to distinguish, need to carry out following step S109.
The IMSI that stores in S109, the use EFS file initiates register requirement to its belonging network; If succeed in registration, execution in step S112 then; If registration is unsuccessful, and the reason of refusal registration be this IMSI not in attaching position register HLR, execution in step S110 and step S111; If registration is unsuccessful, but the reason of refusal registration is other reasons except aforementioned " IMSI is not in attaching position register ", so also turns to execution in step S112.
If network refusal registration, and the reason of refusal be this IMSI not in HLR, prove that so the user has changed SIM card legally, but the Subscriber Number in this SIM card is consistent with the Subscriber Number that this wireless terminal locks.If network is accepted registration, perhaps refusal is registered as other reasons, and employed SIM card was current still effective when this wireless terminal locking of user number then was described, the SIM card of current insertion wireless terminal device is illegal jack per line card.
IMSI in the 3rd logo file of the IMSI replacement EFS file of the SIM card of the current insertion that S110, use are read; Use first mapping value to replace the mapping value of IMEI and Subscriber Number in first logo file of EFS file; And use second mapping value to replace the mapping value of IMSI and Subscriber Number in second logo file of EFS file.
S111, allow this wireless terminal device to be used.
Among this step S111, after the descriptor of the predefine port that this wireless terminal device shines upon, add the normal revision of using of indication and count revision number, (User Interface, UI) this wireless terminal device allows to be used with the user interface of informing this wireless terminal device.
S112, forbid that this wireless terminal device is used.
Serial ports product mark (Product ID in this wireless terminal device mapping, PID) and identification of the manufacturer (Vendor ID, VID) add the revision number that indication bans use of behind the descriptor, forbid being used with this wireless terminal device of UI of informing this wireless terminal device, simultaneously, each port of this wireless terminal also is closed, and prevents from illegally to be cracked.
