Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
Basic thought of the present invention is: form 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, certification and encrypting module, memory module), this base station can be simulated active wireless network function but can not be provided communication service, can simulate position updating process, hereinafter described base station all refers to this particular base station.When mobile communication terminal detects the signal that this base station coverage area is stronger and does not have communication service, this mobile communication terminal is launch position update request initiatively, this base station simulation active wireless network receives this position updating request, and obtains the IMEI of current mobile communications terminal in position of mobile communication terminal renewal process or authentication and ciphering process.
Here, the described IMEI by position updating process acquisition current mobile communications terminal specifically comprises two kinds of situations: after base station acquisition current mobile communications Termination ID is also resolved, if the mobile communication terminal ID obtained is IMEI, the then IMEI of mobile communication terminal that obtains of base station stored, sending position updating request refusal to current mobile communications terminal more afterwards, is that current mobile communications terminal returns active wireless network; If the mobile communication terminal ID obtained is not IMEI, then base station is induced the IMEI of current mobile communications terminal to report self and is stored, and sends location updating refusal more afterwards, make current mobile communications terminal return active wireless network to current mobile communications terminal.Wherein, described active wireless network refers to can provide the mobile communications network of normal communications traffic for mobile communication terminal.
The described IMEI by authenticated encryption Procedure Acquisition current mobile communications terminal specifically comprises: when base station obtains the position updating request of mobile communication terminal initiation, authentication and CIPHERING REQUEST is sent to it, the authentication returned by the current mobile communications terminal received and encrypted response are obtained the international mobile equipment identification number IMEI of current mobile communications terminal and store, send location updating refusal to current mobile communications terminal more afterwards, make current mobile communications terminal return active wireless network.
Base station of the present invention obtains the implementation method of mobile communication terminal IMEI as shown in Figure 1 by position updating process, comprises the following steps:
Step 101: base station checks current network conditions, carries out corresponding configuration according to scanning result to self.
Here, the scanning configuration step of described base station, mainly find and configure suitable transmitting power, coverage, cell parameter, frequency etc., making base station signal in this base station range be better than other network signal of location, to make mobile terminal more easily access.Like this, mobile terminal, through this base station institute overlay area, detects the better community of signal, i.e. the community of this base station camouflage, can to this community own base station launch position update request.
Step 102: mobile communication terminal Sampling network signal, obtains signal stronger in base station coverage area.
Here, described base station is namely for forming 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, certification and encrypting module, memory module).
Step 103: mobile communication terminal, according to the signal obtained, when not having communication service, initiatively sends position updating request to described base station.
Step 104: judge whether position updating request sends successfully, if successfully sent, then performs step 105; Otherwise, return step 102.
Here, specifically how judging whether position updating request sends is successfully prior art, is not described in detail in this.
Step 105: described base station simulation active wireless network receives the position updating request that mobile communication terminal is sent, and obtains current mobile communications Termination ID.
Step 106-107: the mobile communication terminal ID obtained is resolved in described base station, judges that whether the mobile communication terminal ID that resolves is the IMEI of mobile communication terminal, if the ID resolved is IMEI, then performs step 110; Otherwise, perform step 108.
Step 108: described base station sends to current mobile communications terminal and reports IMEI to ask.
Step 109: after reporting IMEI to ask described in current mobile communications terminal receives, report the IMEI of self to described base station.
Step 110: described base station obtains the IMEI of current mobile communications terminal and stores.
Here, described storage can be stored in the user list pre-set by obtained mobile communication terminal IMEI.
Step 111: described base station sends position updating request refusal to current mobile communications terminal; Mobile communication terminal returns active wireless network after receiving described position updating request refusal.
The implementation method of authenticated encryption Procedure Acquisition mobile communication terminal IMEI is passed through as shown in Figure 2 in base station of the present invention, comprises the following steps:
Step 201: base station checks current network conditions, carries out corresponding configuration according to scanning result to self.
Step 202: mobile communication terminal Sampling network signal, obtains signal stronger in base station coverage area.
Step 203: mobile communication terminal, according to the signal obtained, when not having communication service, initiatively sends position updating request to described base station.
Step 204: judge whether position updating request sends successfully, if successfully sent, then performs step 205; Otherwise, return step 202.
Step 205: described base station simulation active wireless network receives the position updating request that mobile communication terminal is sent.
Step 206: described base station sends authentication and CIPHERING REQUEST to current mobile communications terminal.
Step 207: after current mobile communications terminal receives above-mentioned authentication and CIPHERING REQUEST, to the return authentication of described base station and encrypted response.
Step 208: described base station receives described authentication and the encrypted response of the return of current mobile communications terminal, therefrom obtains the international mobile equipment identification number IMEI of current mobile communications terminal and stores.
Step 209: described base station sends position updating request refusal to current mobile communications terminal; Mobile communication terminal returns active wireless network after receiving described position updating request refusal.
Step 101-209 is the complete procedure that base station obtains mobile communication terminal IMEI, in actual applications, after mobile communication terminal detects the new base station coverage area that signal is stronger, upgrade to this base station launch position at any time when there is no communication service, in the position updating process of this mobile communication terminal or in authenticated encryption process, base station just can obtain the IMEI of this mobile communication terminal and store, because the process of this acquisition and storage IMEI is very short, the proper communication of active wireless network normal operation and mobile communication terminal can not be affected.
