Description
Technical field
The present invention relates to electronic information technical field more particularly to a kind of pseudo-base station detection method and a kind of mobile terminals.
Background technology
Since 2G communication networks are using unidirectional authentication, i.e., only 2G base stations authenticate mobile terminal, and mobile terminal
But 2G base stations are not authenticated, therefore mobile terminal is accessed pseudo-base station by criminal using this defect, with to mobile terminal
It sends refuse messages and even carries out fraud, significantly impact user's life.Although 4G communication networks are using two-way mirror
Power method can effectively avoid the upper pseudo-base station of mobile terminal connection, but current 4G cell phone all supports 2G communication networks, as long as
4G communication networks are disturbed, the network of mobile terminal can still fall back to 2G communication networks, and such GSM pseudo-base stations in the same old way can
Endanger mobile terminal.It can be said that no matter using 3G, 4G cell phone, it can not be real as long as mobile terminal supports the network format of 2G
The interference for avoiding GSM pseudo-base station refuse messages.In addition, for the manufacturing technology of pseudo-base station, even new LTE puppet bases
It stands, it is also by means of GSM pseudo-base stations, therefore to the research of GSM pseudo-base stations whithin a period of time still to send refuse messages
With substantial worth.
In addition, existing pseudo-base station detection method mainly includes in the following manner：
（1）The support of hardware is needed, the drawback is that, of high cost, use scope is small.
（2）Just start the detection to pseudo-base station after refuse messages are received, the drawback is that, detection not in time, can not be timely
Notify user.
（3）It is simply simple GSM pseudo-base stations are detected, and the flicker variation of intermediate network types, the drawback is that
Without timely carrying out pseudo-base station detection, cause testing result that can not timely feedback to user.
（4）Detect whether change in signal strength rate is more than normal value, the drawback is that：Since signal strength values are with several factors
It is related, therefore the Detection accuracy of this method is not high.
The content of the invention
It is an object of the invention to provide a kind of pseudo-base station detection method and mobile terminal, at low cost, applied widely,
Detection is in time and accuracy rate is high.
To achieve these goals, the invention discloses a kind of pseudo-base station detection method, mainly include the following steps that：
The network type of mobile terminal is monitored, when network type becomes unknown network type from 2G communication networks, judges movement
Terminal connection is pseudo-base station.
Further, it is further comprising the steps of：
The network type of mobile terminal is monitored, when first network type is 2G communication networks, starts timing first network type
The t1 that holds time；
When first network type becomes the second network type, judge whether the second network type is unknown network type, if so,
And the t1 that holds time of first network type then judges that mobile terminal connection is pseudo- base less than a default time threshold T1
It stands.
Further, it is further comprising the steps of：
One default time threshold T2 is set, when the t1 that holds time of first network type is less than threshold value T1 and the second network type
After unknown network type, judge whether mobile terminal receives new message in time threshold T2, if so, judging mobile terminal
Connection is pseudo-base station.
Further, it is further comprising the steps of：
When the t1 that holds time of first network type is less than threshold value T1, and judge that mobile terminal has received new message, when parsing this
When short message includes preset characters, then judge that mobile terminal connection is pseudo-base station.
Further, it is further comprising the steps of：
One default time threshold T2 is set, when the t1 that holds time of first network type is less than threshold value T1 and the second network type
After unknown network type, judge whether mobile terminal receives new message in time threshold T2, if receiving new message and parsing
The short message includes preset characters, then judges that mobile terminal connection is pseudo-base station.
On the other hand, to achieve these goals, the invention also discloses a kind of mobile terminal, detected including network single
Member, the network detection unit is used to monitor the network type of mobile terminal, when network type becomes unknown from 2G communication networks
During network type, judge that mobile terminal connection is pseudo-base station.
Further, a kind of mobile terminal, including network detection unit, time quantum, wherein：
The network detection unit is used to monitor the network type of mobile terminal, when first network type is 2G communication networks,
Trigger the t1 that holds time that the time quantum starts timing first network type；
The network detection unit is additionally operable to when first network type becomes the second network type, judges that the second network type is
It is no for unknown network type, if so, and first network type the t1 that holds time it is default less than the network detection unit when
Between threshold value T1, then judge mobile terminal connection be pseudo-base station.
Further, the mobile terminal further includes short message detection unit, and the network detection unit is additionally operable to setting one
Default time threshold T2 is unknown network when the t1 that holds time of first network type is less than threshold value T1 and the second network type
After type, the short message detection unit also judges whether mobile terminal receives new message in time threshold T2, if so, judging
Mobile terminal connection is pseudo-base station.
Further, the mobile terminal further includes short message detection unit, when the t1 that holds time of first network type is small

One step it is described in detail.
Although the step in the present invention is arranged with label, it is not used to limit the precedence of step, unless
Specify the order of step or based on the execution of certain step needs other steps, otherwise the relative rank of step is
It is adjustable.
Description of the invention mainly considers from following dimension：
（1）Pseudo-base station connects mobile terminal using 2G communication networks, can be then switched to when sending refuse messages to mobile terminal
One non-2G, non-3G, the dedicated network of non-4G, if therefore the network type of mobile terminal change, be likely to be because
Caused by pseudo-base station reason.
（2）Pseudo-base station is generally shorter using the time of dedicated network transmission short message and less than an empirical value.
（3）Pseudo-base station, generally can be short in a shorter interior transmission after being switched to send the dedicated network of short message
Letter.
（4）The short message that pseudo-base station is sent generally comprises some conventional characters.
Wherein,（1）For basic scheme, that is, the network type of mobile terminal is monitored, when network type is become by 2G communication networks
For unknown network type when, judge mobile terminal connection be pseudo-base station.Those skilled in the art can exist according to actual needs
