Description
Technical Field
The invention belongs to the technical field of communication, and particularly relates to an NPO mobile phone fraud tracing method and system.
Background
The NPO mobile phone means NO POWER ON, and means that the mobile phone is not turned ON to return to a factory, that is, the NPO phenomenon occurs in a new mobile phone in a guarantee period, and a manufacturer is obligated to return to the factory for detection and maintenance. According to the current regulations of continents, the newly purchased mobile phone can be returned without reason when the mobile phone cannot be started or has other faults (namely 'no power on', namely NPO mobile phone) within 14 days, or the newly purchased mobile phone can be freely replaced if the mobile phone cannot be started within 1 year after being sold for 14 days.
A few lawbreakers purchase real mobile phones by using quality guarantee service terms provided by mobile phone manufacturers, then detach the mobile phone main board, change the mobile phone main board into a fake main board purchased from other places, replace the real main board with the fake main board, then take the mobile phone back to a shop for goods return, and gain profits in a mode of cheating the main board. Furthermore, a fake NPO mobile phone is directly purchased, then a new phone can be freely replaced according to the rule that a mobile phone manufacturer can not be started up within 1 year after selling for 14 days, a guarantee reservation is carried out on a mobile phone official network, then the NPO mobile phone is taken to a mobile phone store, and the mobile phone can not be started up as a required phone replacement.
Aiming at the novel fraud behavior that illegal persons use the return policy and product detection loopholes of mobile phone manufacturers, the mobile phone manufacturers often cannot accurately distinguish false mobile phones due to the regulations in the aspects of technology and after-sale processes, and mistakenly think that the false mobile phones conform to the replacement regulations and provide replacement service, so that the mobile phone manufacturers suffer huge economic loss.

Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Example 1:
the embodiment provides an NPO mobile phone fraud pursuit method.
Firstly, the background of the NPO mobile phone is introduced, and the fraud behavior of the NPO mobile phone is characterized in that: the lawbreaker buys the real mobile phone A, then uses the NPO mobile phone B to go to a sales shop for maintenance/replacement, and successfully changes the NPO mobile phone B into the real mobile phone C, and then sells the two real mobile phones A and C.
Secondly, from the perspective of the terminal manufacturer, the real mobile phone a cannot be used, and at this time, the corresponding IMEI number of the mobile phone a, i.e. the IMEI, is the IMEI numberAIs not supposed to occur; but from the core network of the operator, the IMEI numbers of all the network-accessing terminals (including the IMEI corresponding to the a handset) can be detectedA) And through comparison of the terminal manufacturer and the core network data of the telecom operator, NPO fraud can be found, and a basis is provided for the terminal manufacturer to retrieve the A mobile phone.
Firstly, establishing an IMEI information base of NPO mobile phone of terminal manufacturer
1. Recording IMEI number of all maintenance mobile phones, using IMEIARepresents;
2. recording all IMEI numbers after changing machine, using IMEICRepresents;
3. establishing a database table B, and storing IMEIAAnd IMEICThe correspondence relationship of (a) is shown in the following table.
| Name of field | Type of field | Remarks for note |
| IMEIA | varchar(15) | Source IMEI number |
| IMEIB | Varchar(15) | IMEI number after changing machine |
| TIME | datetime | Time for changing machine |
Secondly, collecting and storing core network signaling data
In the mobile signaling network, as long as the terminal is in a power-on networking state, no matter whether a call is in progress, signaling interaction can be periodically or irregularly generated, and key fields of core network signaling data are collected and stored, including: IMSI, IMEI, time, LAC, CI.
Establishing a data table to store the above important fields includes that the table is defined as follows:
and calculating the corresponding geographic position according to the LAC and the CI, and storing the geographic position and the collected mobile terminal information into a mobile phone tracking information base together, wherein the mobile phone tracking information base stores information of all the mobile phone terminals which are accessed to the network.
According to the background handed over above, as shown in fig. 1, the steps of the NPO mobile phone fraud tracking method in this embodiment specifically include the following steps:
step one, regularly acquiring the information of each mobile phone terminal in a mobile phone tracking information base.
Specifically, for example, a day is taken as a unit, the signaling message of each mobile phone terminal in the mobile phone tracking information base is acquired, and the IMEI number, IMSI number, time, LAC, and CI information of the mobile phone terminal are acquired.
And step two, comparing the acquired information of the mobile phone terminal with the pre-stored information of the NPO mobile phone terminal.
Specifically, the IMEI number of each mobile phone terminal acquired in the step one is retrieved and compared in a pre-stored terminal manufacturer NPO mobile phone IMEI information base.
And step three, if the acquired information of the mobile phone terminal is matched with the pre-stored information of the NPO mobile phone terminal, sending the information of the mobile phone terminal to a terminal manufacturer for the terminal manufacturer to trace the mobile phone terminal.
Specifically, if the IMEI number of each mobile phone terminal acquired in the step one in the step two is retrieved and compared in a pre-stored NPO mobile phone IMEI information base of a terminal manufacturer to find that no coincidence exists, all terminals are considered to be normally used and do not need to be processed; and if the acquired IMEI number of the mobile phone terminal is matched with the prestored IMEI number of the NPO mobile phone terminal, acquiring the LAC and the CI of the mobile phone terminal according to the IMEI number of the mobile phone terminal to calculate the position information of the mobile phone terminal, and sending the acquired IMEI number and the position information of the mobile phone terminal to a terminal manufacturer for the terminal manufacturer to search for the mobile phone.
Through the steps, the NPO mobile phone fraud behaviors can be effectively identified, and effective pursuit behaviors can be carried out.
Aiming at the fraud behavior of illegal personnel by utilizing the return policy of mobile phone manufacturers and product detection loopholes, the method of the embodiment can find the deceived mobile phones in time, provide a pursuit basis for related departments, so as to recover related losses and improve the cost of NPO mobile phone fraud.
