Embodiment Construction

[0032] Mobile terminals produced by regular manufacturers, such as mobile phones, usually have a unique IMEI, that is, there is a one-to-one correspondence between IMEI and terminal equipment; while illegal terminals such as counterfeit mobile phones and black mobile phones usually share the same IMEI for multiple terminal equipment , so the illegal IMEI can be identified according to the number of users corresponding to the IMEI. The present invention will be further described through specific embodiments below in conjunction with the accompanying drawings.

[0033] Please refer to figure 1 , the method for identifying illegal IMEI described in the embodiment of the present invention, comprises the following steps:

[0034] Step 11, obtain the communication bills of the mobile terminal in the network within a predetermined period of time, each of which includes the IMEI and user identification of the mobile terminal, and the communication bills can specifically be voice comm...
