Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of method of confirming global mobile communication base station simulator.
Background technology
GSM(globalsystemformobilecommunications, global system for mobile communications) base station simulator is a kind of testing equipment that can simulate all signals that send a GSM mobile communication base station, this equipment can carry out with mobile subscriber terminal the information interaction of various air interface aspects. GSM base station simulator, except comprising transceiver, BBP, also possesses the partial function of the equipment such as base station controller, mobile switching centre, mobile user affiliation location register.
The main application of GSM base station simulator is that mobile subscriber terminal (GSM mobile handset) is tested. Now GSM base station simulator can confirm that whether mobile subscriber terminal exists, and voice call etc. can be sent short messages mutually, dial or answer to mobile subscriber terminal in the signal cover of GSM base station simulator.
Generally GSM base station simulator uses between the shielding that does not have mobile communications network to cover. In the time using under the environment that GSM base station simulator is having mobile communications network to cover, if the signal strength signal intensity of GSM base station simulator is greater than the GSM base station signal strength of operator, mobile subscriber terminal can select to enter GSM base station simulator network, but not carrier network. Because GSM base station simulator is not truly connected with the mobile communications network of operator, therefore enter GSM base station simulator signal cover mobile subscriber terminal cannot with carrier network in mobile subscriber terminal proper communication, comprise transmitting-receiving short message, dial or answer voice call etc. In addition, because both wireless signal coverages often partly overlap, wireless signal frequency is also identical or close, and GSM base station simulator can produce and disturb the mobile communications network of operator in this case, thereby the normal operation of mobile communications network is caused to harmful effect. Because GSM base station simulator can be simulated all signals that send mobile communication base station, be therefore difficult to from signal, the base station of GSM base station simulator and operator be distinguished.

Compared with prior art, the invention has the beneficial effects as follows:
A kind of method of confirming global mobile communication base station simulator in the present invention, utilize the disappearance of GSM base station simulator to mobile subscriber terminal authentication functions, the existence that can accurately detect GSM base station simulator by invalid SIM and common GSM mobile handset whether, simple to operate, result is accurate.
Brief description of the drawings
Fig. 1 is a kind of method flow block diagram of confirming global mobile communication base station simulator of the present invention.
Detailed description of the invention
Below in conjunction with schematic diagram and concrete operations embodiment, the invention will be further described.
As shown in fig. 1, a kind of method of confirming GSM base station simulator, wherein, comprises the following steps:
Step 1: the Subscriber Identity Module of at least one Zhang Wuxiao is provided, and described Subscriber Identity Module comprises public land mobile network information (PLMN, PublicLandMobileNetwork);
In one embodiment of the invention, this invalid Subscriber Identity Module (SIM) can be the GSM mobile communications network of originally accessible operator but cancel because of the reason such as expired, to report the loss, cannot normally access the SIM of GSM mobile communications network, wherein, this KI value remains itself definite KI value.
In another embodiment of the present invention, this invalid Subscriber Identity Module can be homemade SIM, this SIM is applicable to or compatible GSM network, particularly, in this invalid Subscriber Identity Module except comprising PLMN information, also comprise integrated circuit identification card information (IntegrateCircuitCardIdentity, ICCID), whole world mobile identification number information (InternationalMobileSubscriberIdentification, etc. and KI (Keyidentifier IMSI), Ki), this KI can be chosen to be definite KI value arbitrarily.
Step 2: the mobile communications device that at least one identification global mobile communication network is provided;
Step 3: determine scope to be tested, Subscriber Identity Module is inserted among mobile communications device, definition decision condition information, described decision condition information comprises public land mobile network information;
Particularly, in the place that need to detect GSM simulator, can access the SIM of GSM network and insert among the mobile communications device that can identify GSM network, open communicator.
Step 4: observe and judge decision condition information;
In one embodiment of the invention, this decision condition information is except comprising PLMN information, comprise mobile country code (MCC), mobile network code, MNC (MNC) in addition, this decision condition information can also comprise the signal strength signal intensity indication information that mobile communications device is provided with. By observing in mobile communications device whether decision condition information can be detected, realize the detection of GSM base station simulator is determined.
Step 5: if show decision condition information, succeed in registration,, in the scope of described test, have GSM base station simulator;
Step 6: if do not show decision condition information, registration failure, now, can judge that GSM base station simulator does not exist; All right, by repeating the method for above-mentioned steps 1 to step 4, repeatedly carry out monitoring observation, whether exist to reach correct judgement GSM base station simulator.
In one embodiment of the invention, use the mobile phone of compatible GSM network, at tested point, a SIM cards of mobile phones calcellation or homemade GSM network that cannot access carrier is inserted in mobile phone, and start, now according to whether showing on mobile phone screen that decision condition information judges, because this SIM is the identification card that impossible access the GSM network of any operator, thereby, when show decision condition information on mobile phone screen time, represent this mobile phone searching and accessed GSM network, now show to have GSM base station simulator at tested point; Otherwise, through repeatedly testing detection, in mobile phone, do not show decision condition information, for example, on mobile phone, be shown as " SIM registration failure ", or " only for urgent call ", show network registry failure, there is not GSM base station simulator at tested point.
In embodiments of the invention, observing the decision condition information on mobile phone screen the method for judging has utilized GSM base station simulator can not carry out authentication to mobile subscriber terminal, even if or started authorizing procedure, but can not make to authenticating result the feature of any response, therefore in the time showing mobile country code (MCC), mobile network code, MNC (MNC) and signal strength signal intensity instruction on mobile phone screen, can judge that base station simulator exists; When being shown as " SIM registration failure ", or " only for urgent call ", or can judge base station simulator not while not showing mobile country code (MCC), mobile network code, MNC (MNC) and signal strength signal intensity instruction, can continue to observe.
Above specific embodiments of the invention be have been described in detail, but the present invention is not restricted to specific embodiment described above, it is just as example. To those skilled in the art, any equivalent modifications and alternative also all among category of the present invention.
