Embodiment
Below in conjunction with accompanying drawing the present invention is further specified.
Basic thought of the present invention is: constitute the particular base station that can obtain mobile communication terminal IMEI by radio-frequency front-end, modulator-demodulator, codec, protocol stack and upper application module (scanning configuration module, location update processing module, authentication and encrypting module, memory module); This base station can be simulated the current wireless network function but communication service can not be provided; Can simulate the completing place renewal process, hereinafter described the base station all refers to this particular base station.When mobile communication terminal detects the stronger signal of this base station coverage area and does not have communication service; This mobile communication terminal is initiatively initiated position updating request; This base station simulation current wireless network receives this position updating request, and in position of mobile communication terminal renewal process or authentication and ciphering process, obtains the IMEI of current mobile communication terminal.
Here; The said IMEI that obtains current mobile communication terminal through position updating process specifically comprises two kinds of situation: after the base station obtains current mobile communication terminal ID and resolves; If the mobile communication terminal ID that is obtained is IMEI; The IMEI of the mobile communication terminal that then base station stored obtained sends the position updating request refusal to current mobile communication terminal afterwards again, is that current mobile communication terminal returns the current wireless network; If the mobile communication terminal ID that is obtained is not IMEI, then the base station induces current mobile communication terminal to report self IMEI and storage, sends the position to current mobile communication terminal more afterwards and upgrades refusal, makes current mobile communication terminal return the current wireless network.Wherein, said current wireless network is meant can provide proper communication professional mobile communications network for mobile communication terminal.
The said IMEI that obtains current mobile communication terminal through the authenticated encryption process specifically comprises: when the base station obtains position updating request that mobile communication terminal initiates; Send authentication and enciphering request to it; The international mobile equipment identification number IMEI that authentication through the current mobile communication terminal repayment of receiving and encrypted response obtain current mobile communication terminal also stores; Send the position to current mobile communication terminal more afterwards and upgrade refusal, make current mobile communication terminal return the current wireless network.
Base station of the present invention is as shown in Figure 1 through the implementation method that position updating process obtains mobile communication terminal IMEI, may further comprise the steps:
Step 101: base station inspection current network conditions, according to scanning result self is carried out corresponding configuration.
Here; The scanning configuration step of said base station; Mainly be to find and dispose suitable transmission power, coverage, cell parameter, frequency etc., make the interior base station signal of this base station range be better than other network signal of location, so that portable terminal is inserted more easily.Like this, portable terminal detects the better sub-district of signal through this base station institute overlay area the time, and promptly position updating request can be initiated in the base station in the sub-district of this base station camouflage under this sub-district.
Step 102: mobile communication terminal detects network signal, obtains signal stronger in the base station coverage area.
Here, said base station is promptly for constituting the particular base station that can obtain mobile communication terminal IMEI by radio-frequency front-end, modulator-demodulator, codec, protocol stack and upper application module (scanning configuration module, location update processing module, authentication and encrypting module, memory module).
Step 103: mobile communication terminal when not having communication service, initiatively sends position updating request to said base station according to the signal that obtains.
Step 104: judge whether position updating request sends success, if successfully send, then execution in step 105; Otherwise, return step 102.
Here, how to judge that specifically whether position updating request sends is prior art successfully, is not described in detail in this.
Step 105: said base station simulation current wireless network receives the position updating request that mobile communication terminal is sent, and obtains current mobile communication terminal ID.
Step 106-107: the mobile communication terminal ID that said base station resolves obtained, judge whether the mobile communication terminal ID that is resolved is the IMEI of mobile communication terminal, if the ID that resolves is IMEI, then execution in step 110; Otherwise, execution in step 108.
Step 108: the IMEI request that reports is sent to current mobile communication terminal in said base station.
Step 109: after current mobile communication terminal is received the said IMEI of reporting request, report the IMEI of self to said base station.
Step 110: said base station obtains the IMEI and the storage of current mobile communication terminal.
Here, said storage can be that the mobile communication terminal IMEI that is obtained is stored in the preset user tabulation.
Step 111: the position updating request refusal is sent to current mobile communication terminal in said base station; Mobile communication terminal returns the current wireless network after receiving said position updating request refusal.
The implementation method that base station of the present invention obtains mobile communication terminal IMEI through the authenticated encryption process is as shown in Figure 2, may further comprise the steps:
Step 201: base station inspection current network conditions, according to scanning result self is carried out corresponding configuration.
Step 202: mobile communication terminal detects network signal, obtains signal stronger in the base station coverage area.
Step 203: mobile communication terminal when not having communication service, initiatively sends position updating request to said base station according to the signal that obtains.
Step 204: judge whether position updating request sends success, if successfully send, then execution in step 205; Otherwise, return step 202.
Step 205: said base station simulation current wireless network receives the position updating request that mobile communication terminal is sent.
Step 206: authentication and enciphering request are sent to current mobile communication terminal in said base station.
Step 207: after current mobile communication terminal is received above-mentioned authentication and enciphering request, to repayment authentication of said base station and encrypted response.
Step 208: said base station receives the said authentication and the encrypted response of current mobile communication terminal repayment, therefrom obtains the international mobile equipment identification number IMEI and the storage of current mobile communication terminal.
Step 209: the position updating request refusal is sent to current mobile communication terminal in said base station; Mobile communication terminal returns the current wireless network after receiving said position updating request refusal.
Step 101-209 is the complete procedure that the base station obtains mobile communication terminal IMEI; In practical application; After mobile communication terminal detects the stronger new base station coverage area of signal; When not having communication service, initiate the position to this base station at any time and upgrade, in the position updating process of this mobile communication terminal or in the authenticated encryption process, the base station just can obtain the IMEI and the storage of this mobile communication terminal; Because this process of obtaining and storing IMEI is very short, can not influence the proper communication of normal operation of current wireless network and mobile communication terminal.
