Problems solved by technology

[0004] As mentioned above, the problem existing in the terminal in the prior art is that for the act of deleting the original ESN area recorded in the NV area and writing a new record, because there is no corresponding preventive measure, it cannot be recorded in the network. Search out the illegally copied terminal

Embodiment Construction

[0014] Attached below figure 1 And attached figure 2 , the process of performing corresponding processing to prevent illegal use of the mobile communication terminal in the present invention having the above structure will be described.

[0015] In the mobile communication terminal production process, the electronic serial number (ESN) of the terminal is recorded for a non-volatile (NV: Non-Volatile) area (step S1).

[0016] like figure 1 As shown in , different from this record, the above-mentioned electronic serial number (ESN) is recorded in an area of ​​the flash memory 1 (for example: Sector#0). And, the area (Sector#0) of the above-mentioned flash memory 1 is designated as an area that will never be deleted even if all software in the terminal is deleted and re-downloaded (steps S2, S3).

[0017] Thereafter, after the terminal is listed and sold to the user, the user will start to use the terminal. At this time, for some reason, when recording a new terminal ESN in t...

Abstract

The present invention discloses a technique of preventing the illegally copying and using the mobile communication terminal with electronic serial number. The present invention is realized by the following procedures: the first procedure, recording the serial number which is same to the serial number storing in the nonvolatile semiconductor memory zone at certain area of the flash memory, and putting it on the market after it has been permanently locked; the second procedure, when the electronic serial number storing in the nonvolatile semiconductor memory zone is reregistered, comparing the new-recording electronic serial number to the electronic serial number in the flash memory, to confirm whether the two numbers are same; the third procedure, after the confirming result, if the two serial numbers do not accord to each other, transmitting the two different electronic serial numbers to the network end and taking required measures. Using the invention it can definitely prevent the illegally using based on the copying the electronic serial numbers of the terminal.

Description

technical field [0001] The present invention relates to a technology for preventing illegal copying and use of mobile communication terminals, and more specifically, relates to a technology for preventing illegal use of mobile communication terminals from recording new electronic serial numbers and illegal use of terminals after illegal reading. method of communication terminal. Background technique [0002] In recent years, with the rapid increase in the penetration rate of mobile phones, it has become a must-have item in modern life. This kind of mobile phone can not only provide the original voice call service, but also provide various data transmission services and other various additional services. According to its function, it can also be called a multimedia communication device. [0003] In the case of a CDMA terminal, authentication is based on the Electronic Serial Number (ESN: ElectronicSerial Number) and the Mobile Identification Number (MIN: Mobile Identificatio...
