The base station for causing attachment to fail is determined as doubtful pseudo-base station, to improve the accuracy of doubtful pseudo-base station identification.
In an alternative embodiment, terminal can count the number of Attachments failure, then by the number and make a reservation for
Threshold value is compared；When the number is more than predetermined threshold, base station is determined as doubtful pseudo-base station, i.e. execution step 330；When this
When number is less than predetermined threshold, the step of counting the number that Attachments fail is continued to execute, until the number is more than predetermined
Threshold value or terminal stop when adhering to successfully.Predetermined threshold is illustrated below.
It is provided in relevant communication standards, when continuous 5 attachments of terminal and base station fail, meeting opening timing device, by base station
Corresponding cell can just reactivate after forbidding scheduled duration.If base station is pseudo-base station, which can lead to terminal continuous 5
Secondary attachment failure, thus make terminal in cell reselection gravity treatment to the corresponding cell of another pseudo-base station, so, can be set predetermined
Threshold value is less than 5, for example predetermined threshold can be 4 or 3 or 2 etc., and this embodiment is not limited.
Step 330, if number is more than predetermined threshold, base station is determined as doubtful pseudo-base station.
Step 340, doubtful pseudo-base station is verified, determines whether doubtful pseudo-base station is pseudo-base station according to verification result.
Normal base station may also can because of leading to failed authentication due to certain, in order to avoid normal base
Station is identified as pseudo-base station, and terminal can also continue to verify doubtful pseudo-base station, and is determined according to verification result doubtful
Pseudo-base station is pseudo-base station or normal base station, to improve the accuracy of pseudo-base station identification.
In conclusion pseudo-base station recognition methods provided in this embodiment is built if base station is pseudo-base station in terminal and base station
After vertical RRC connection, base station may lead to terminal attachment failure before with terminal successful authentication, to make terminal and GSM
Connection is established in base station, which is pseudo-base station.Above-mentioned characteristic based on pseudo-base station, terminal can count Attachments failure
Number, due to attachment be unsuccessfully occur before base station and terminal successful authentication, so, if number is more than predetermined threshold,
Base station can be then determined as to doubtful pseudo-base station, then, terminal can continue to verify doubtful pseudo-base station, and according to verifying

Step 341, the Location Area Identification LAI list of terminal, the cell accessed in the LAI list comprising terminal are obtained
LAI.
Terminal obtains the LAI of the cell, and the LAI is added after one corresponding cell in normal base station of every access
Into LAI list, then the LAI of the cell accessed in the LAI list comprising terminal.
Terminal can obtain the LAI of the corresponding cell of the doubtful pseudo-base station after getting doubtful pseudo-base station, and detect
Whether include the LAI in LAI list, if including the LAI in LAI list, thens follow the steps 342, it should if not including in LAI list
LAI thens follow the steps 343.
Step 342, if including the LAI of cell corresponding to doubtful pseudo-base station in LAI list, doubtful pseudo-base station is generated not
It is the verification result of pseudo-base station.
If in LAI list including the LAI, it can determine and access the corresponding cell of the doubtful pseudo-base station before terminal,
Also it can think that the doubtful pseudo-base station is normal base station, it is the verification result of pseudo-base station that terminal, which generates doubtful pseudo-base station not,.
Step 343, if not including the LAI of cell corresponding to doubtful pseudo-base station in LAI list, doubtful pseudo-base station is generated
It is the verification result of pseudo-base station.
If in LAI list including the LAI, it is corresponding small can to determine that terminal did not accessed the doubtful pseudo-base station before
Area can also think that the doubtful pseudo-base station is pseudo-base station, and terminal generates the verification result that doubtful pseudo-base station is pseudo-base station.
In another alternative embodiment, terminal can disappear according to the system of AS (Access Stratum, access layer)
Breath is to verify doubtful pseudo-base station, then step 340 may include the following steps:
Step 344, the system message that base station is sent is received.
In the present embodiment with system message for for SIB (System information block, system information block) 1 into
Row explanation.
Step 345, doubtful pseudo-base station is verified according to system message.
Due to may include much information in SIB1, below to the stream for verifying doubtful pseudo-base station by taking wherein several information as an example
Journey is illustrated.
In the first implementation, step 345 may include the following steps:
Step 3451, public land mobile network PLMN (Land Mobile Network, the public land in SIB1 are obtained
Ground mobile network) mark.
In general, a normal base station can provide service to the user of an operator, and an operator corresponds to one
A PLMN mark, so, a PLMN mark can be carried in the SIB1 that normal base station is sent to terminal.If being carried in SIB1
There is at least two PLMN mark, it may be considered that the base station is pseudo-base station, so, terminal can be identified according to the PLMN in SIB1
Quantity verify doubtful pseudo-base station.
Wherein, the PLMN mark in the available SIB1 of terminal, and compare the quantity and 1 of PLMN mark, if PLMN is identified
Quantity be equal to 1, then follow the steps 3452；If the quantity of PLMN mark is greater than 1,3453 are thened follow the steps.
Step 3452, if the quantity of PLMN mark is equal to 1, generating doubtful pseudo-base station not is the verification result of pseudo-base station.
Step 3453, if the quantity of PLMN mark is greater than 1, the verification result that doubtful pseudo-base station is pseudo-base station is generated.
In the second implementation, step 345 may include the following steps:
Step 3454, it determines whether configured with SIB5 in SIB1, and determines whether to receive what doubtful pseudo-base station was sent
SIB5。
In general, base station if normal needs to send SIB5 to terminal, then SIB5 can be configured in SIB1, and send to terminal
SIB5；Alternatively, base station if normal is not required to send SIB5 to terminal, then SIB5 will not be configured in SIB1, it will not be to terminal
Send SIB5, that is, whether in SIB1 configure SIB5 with whether issue SIB5 need it is corresponding.And if base station be pseudo-base station, can
To configure SIB5 in SIB1 but not send SIB5 to terminal, alternatively, configure SIB5 not in SIB1 but send SIB5 to terminal,
So whether terminal can be according to whether configuring SIB5 in SIB1 and issuing SIB5 and verify doubtful pseudo-base station.
Step 3455, if configured with SIB5 and SIB5 is received in SIB1, alternatively, if SIB5 being not configured in SIB1 and does not connect
SIB5 is received, then generating doubtful pseudo-base station not is the verification result of pseudo-base station.
Step 3456, if SIB5 is not received configured with SIB5 and in SIB1, alternatively, if SIB5 being not configured in SIB1 and connects
SIB5 is received, then generates the verification result that doubtful pseudo-base station is pseudo-base station.
In the third implementation, step 345 may include the following steps:
Step 3457, the configuration parameter of the intra-frequency measurement in SIB1 is obtained.
Intra-frequency measurement is referred to as intra-freq reselect, and the configuration parameter of intra-frequency measurement may include
Allow and not allow, wherein configuration parameter is that allow is used to indicate permission intra-frequency measurement, and configuration parameter is not allow
It is used to indicate and forbids intra-frequency measurement.
Normal base station can allow terminal to carry out intra-frequency measurement, and pseudo-base station can forbid terminal to carry out intra-frequency measurement, so,
Terminal can be according to whether allow intra-frequency measurement to verify doubtful pseudo-base station.
Step 3458, if configuration parameter is used to indicate permission intra-frequency measurement, generating doubtful pseudo-base station is not pseudo-base station
Verification result.
If configuration parameter is allow, it is the verification result of pseudo-base station that terminal, which generates doubtful pseudo-base station not,.
Step 3459, if configuration parameter, which is used to indicate, forbids intra-frequency measurement, generating doubtful pseudo-base station is testing for pseudo-base station
Demonstrate,prove result.
If configuration parameter is not allow, terminal generates the verification result that doubtful pseudo-base station is pseudo-base station.
It should be noted that terminal can be according to one or both of above-mentioned three kinds of implementations or three kinds of implementations
To verify doubtful pseudo-base station.When terminal according at least two implementations to verify doubtful pseudo-base station when, can be according to any
When kind implementation determines that doubtful pseudo-base station is pseudo-base station, the verification result that doubtful pseudo-base station is pseudo-base station is generated；According to institute
Implementation determines doubtful pseudo-base station not when being pseudo-base station, and generating doubtful pseudo-base station not is the verification result of pseudo-base station.
For example, terminal verifies doubtful pseudo-base station with the third implementation according to the first, then terminal can be in determination
The quantity of PLMN mark is greater than 1, or, configuration parameter, which is used to indicate, forbids intra-frequency measurement, or, the quantity of PLMN mark be greater than 1 and
Configuration parameter is used to indicate when forbidding intra-frequency measurement, generates the verification result that doubtful pseudo-base station is pseudo-base station；Determining PLMN mark
The quantity of knowledge is equal to 1 and configuration parameter is used to indicate when allowing intra-frequency measurement, and generating doubtful pseudo-base station not is the verifying of pseudo-base station
As a result.
In the present embodiment, terminal can identify whether base station is pseudo-base station, increases pseudo- base by NAS layers and AS layers of joint
Stand identification accuracy.In addition, being identified for pseudo-base station compared in terms of single, can effectively reduce to normal base station
Erroneous judgement, thus reduce because normal base station be mistaken for pseudo-base station, and cause terminal can not normal registration into network, thus
There is the problem of no-service situation.
Terminal can be combined with two kinds of optional embodiments above to verify doubtful pseudo-base station.For example, terminal can be with
Doubtful pseudo-base station is first verified according to the LAI of the corresponding cell of doubtful pseudo-base station, doubtful pseudo- base is verified further according to system message
It stands；Doubtful pseudo-base station can also be first verified according to system message, verified further according to the LAI of the corresponding cell of doubtful pseudo-base station
Doubtful pseudo-base station, this embodiment is not limited.It is first doubtful to verify according to the LAI of the corresponding cell of doubtful pseudo-base station to terminal below
Like pseudo-base station, the process that doubtful pseudo-base station is verified further according to system message is illustrated, and please refers to Fig. 4.
Step 401, terminal is from first service cell reselection to second service cell.
Step 402, it after RRC connection is established in terminal base station corresponding with second service cell, detects whether because not authenticating
And continuous 4 attachments is caused to fail, if continuous 4 attachments is caused to fail because of not authenticating, then follow the steps 403.
Step 403, terminal detection terminal storage LAI list in whether include second service cell LAI, if LAI arrange
The LAI for not including second service cell in table, thens follow the steps 404.
If including the LAI of second service cell in LAI list, terminal determines that base station is not pseudo-base station, terminates process.
Step 404, whether special parameter is carried in the system information of terminal detection second service cell, if carrying special ginseng
Number, thens follow the steps 405.
Wherein, special parameter includes: that the quantity of PLMN mark is greater than in 1, SIB1 configured with SIB5 and does not receive SIB5,
Alternatively, if SIB5 being not configured in SIB1 and receives SIB5, the configuration parameter of intra-frequency measurement is not allow.
If not carrying special parameter, terminal determines that base station is not pseudo-base station, terminates process.
Step 405, terminal determines that the corresponding base station of second service cell is pseudo-base station.
If realizing Fig. 4 using module, in an alternative embodiment, terminal may include attachment failure detection mould
