It is flat.Cell reselection offset is set as the difficult to target gravity treatment of positive value, otherwise is easy to Target cell gravity treatment.The offset of cell individual character is set as
The difficult of negative value switches to target, otherwise is easy to switch to Target cell.
Present embodiments are specifically described below in conjunction with attached drawing.
Referring to Fig. 2, a kind of method for identifying pseudo-base station provided by the present application, is applied to mobile terminal, the method packet
It includes:
Step S110: the actual value of multiple cell access characteristic parameters of the acquisition for mobile terminal base station.
Step S120: by the actual value of the multiple cell access characteristic parameter and the multiple cell access characteristic parameter
Corresponding default judgment condition is matched, and the multiple corresponding matching characteristic of cell access characteristic parameter is obtained
Value.
By the actual value of cell access characteristic parameter and the corresponding default judgment condition of cell access characteristic parameter
Carry out it is matched during, the decision value that the actual value of cell access characteristic parameter includes with default judgment condition can be compared
It is right, matching characteristic value is determined according to comparison result.
In multiple cell access characteristic parameters, cell access characteristic parameter and difference including difference sensitivity are insensitive
Cell access characteristic parameter, wherein the actual value of the cell access characteristic parameter of difference sensitivity and default judgment condition difference
Bigger, characterization base station is that the probability of pseudo-base station is higher, and the actual value of the insensitive cell access characteristic parameter of difference and default
Judgment condition difference size is for judging whether base station is that pseudo-base station does not influence.It is then used as a kind of mode, it is multiple getting
After cell access characteristic parameter, then the cell access features ginseng of the first classification in the multiple cell access characteristic parameter is obtained
Number and the cell access characteristic parameter of the second classification.Wherein, the cell access characteristic parameter of the first classification is that difference is insensitive
Cell access characteristic parameter, second classification cell access characteristic parameter be difference sensitivity cell access characteristic parameter.
As a kind of mode classification, it is described first classification cell access characteristic parameter include position area LAC information, it is general
It is grouped wireless service mark；The cell access characteristic parameter of second classification includes minimum reception level, control channel maximum
Power level, cell reselection offset, cell reselection lag and periodical position renewing timer.
It whether include described the according in the corresponding default judgment condition of cell access characteristic parameter of first classification
The actual value of the cell access characteristic parameter of one classification determines the corresponding matching of cell access characteristic parameter of first classification
Characteristic value.
For example, the default judgment condition of position area LAC information is [1,2,3 ..., 65534], if position area LAC information
Actual value be 30, then the matching characteristic value of position area LAC information be 0, if the actual value of position area LAC information be 0, position
The matching characteristic value for setting area's LAC information is 1.It should be noted that subsequent for the determination of matching characteristic value can also be in conjunction with pseudo- base
Judgment condition of standing is described further, and is not described further in detail herein.
The actual value of cell access characteristic parameter according to second classification includes with corresponding default judgment condition
The size of the difference of decision value determines the corresponding matching characteristic value of cell access characteristic parameter of second classification.
For example, being [A, Z] for the possibility value range of some cell access characteristic parameter, then it is used as a kind of mode, it is right
The default judgment condition answered can be [A, T], be also possible to [T, Z].For subsequent statement for the sake of simplicity, assuming that [A, T] is default
Judgment condition.
Then, the actual value of cell access characteristic parameter is compared with threshold T, if in default judgment condition model
In enclosing, then the mismatch degree of this feature parameter is 0, if not calculating matching further within the scope of default judgment condition
Characteristic value.Further, if not within the scope of default judgment condition, by other than default judgment condition value interval (T, Z]
N parts are divided into, dividing method includes but is not limited to following two:
Equisection method: being divided into N parts for [T, Z], i.e., each subinterval is respectively [T, T+ (Z-T)/N], (T+ (Z-T)/N, T+
(Z-T)*2/N]、(T+(Z-T)*2/N,T+(Z-T)*3/N]...、((Z-T)*(N-1)/N+T,Z]。
Not equisection method: will (T, Z] be divided into N parts, N parts of size be respectively x, 2x, 3x ... Nx, closer to threshold T
Section is bigger, i.e., the size in the 1st part section is Nx, the 2nd part to N parts of sections of size be respectively (N-1) x ..., x.N parts of areas
Between be respectively [T, T+2*N* (Z-T)/N* (N+1)], (T+2*N* (Z-T)/(N* (N+1)), T+2*N* (Z-T)/(N* (N+1))+
2* (N-1) * (Z-T)/(N* (N+1))], (Z-2* (Z-T)/(N* (N+1)), Z].
When actual value falls in n-th part (1≤n≤N) in the section [T, Z], this feature parameter matching characteristic value is n.
Step S130: being weighted summation to the corresponding matching characteristic value of the multiple cell access characteristic parameter,
Obtain the corresponding pseudo-base station parameter in the base station.
Step S140: the pseudo-base station parameter is compared with parameter preset, when comparison result meets preset condition,
It is pseudo-base station by the identification of base stations.
It should be noted that when determining matching characteristic value in the step 120, it can be in conjunction with default judgment condition and step
Preset condition in S140 confirms.
It is then pseudo-base station by identification of base stations when preset condition is that pseudo-base station parameter is greater than parameter preset as a kind of mode,
And in default judgment condition include when being the parameter of normal Base Station, the cell access characteristic parameter insensitive for difference,
Corresponding characteristic value is 0, and to characterize a possibility that base station is pseudo-base station smaller, and matching characteristic value is 1, then characterizes the base station
A possibility that for pseudo-base station, is bigger.
For example, if the default judgment condition of position area LAC information is [1,2,3 ..., 65534], wherein [1,2,
It 3 ..., 65534] is content included by the position area LAC information of normal Base Station, then in this case, the position got
The actual value of area's LAC information is 30, and 30 is interior in [1,2,3 ..., 65534], then available position area LAC information is corresponding
Matching characteristic value is 0, opposite, if the actual value of the position area LAC information got is 0, and 0 not [1,2,3 ...,
65534] in, then the corresponding matching characteristic value of available position area LAC information is 1.
For the cell access characteristic parameter of difference sensitivity, the corresponding characteristic value the big, shows that the base station is pseudo-base station
Possibility is bigger, therefore, is greater than parameter preset in the pseudo-base station parameter finally calculated, is then pseudo-base station by identification of base stations.Example
Such as, when the minimum possibility value range for receiving level got is [- 99, -96], then the minimum judgment condition for receiving level is
[- 97, -96] are divided into 3 parts by [- 99, -97], then equisection method as described above, each section that equal part obtains be [-
97, -96.67], (- 96.67, -96.34] and (- 96.34, -96.01], the matching characteristic value being corresponding in turn to is 1,2,3.When
The actual value that minimum receives level is -98, then this falls into normal range (NR), and it is 0 that minimum, which receives the corresponding matching characteristic value of level, and
When the minimum actual value for receiving level is -96.66, then the minimum corresponding matching characteristic value of level that receives is 2.Wherein, characteristic value
More high, the mismatch degree for characterizing base station actual value and judgment condition is higher, and include in judgment condition is normal Base Station parameter
In the case where, the mismatch degree the high, shows that the probability that base station is pseudo-base station is also bigger.
In addition, alternatively, in addition to can set judgment condition to include normal Base Station parameter other than, may be used also
With set judgment condition to include pseudo-base station parameter, then in this case, matching characteristic value content then with foregoing manner
On the contrary.For example, if the default judgment condition of position area LAC information is [- 1,0], and the reality of the position area LAC information got
Actual value is still 30, but 30 is interior in [- 1,0], then the corresponding matching characteristic value of available position area LAC information is 0.
A kind of method identifying pseudo-base station provided by the present application, by using to the actual values of multiple cell access parameters into
The analysis of row comprehensive and quantitative, more accurate identifies whether base station is pseudo-base station, improves the accuracy of pseudo-base station identification.
Referring to Fig. 3, a kind of method for identifying pseudo-base station provided by the present application, is applied to mobile terminal, the method packet
It includes:
Step S210: the actual value of multiple cell access characteristic parameters of the acquisition for mobile terminal base station.
Step S220: by the actual value of the multiple cell access characteristic parameter and the multiple cell access characteristic parameter
Corresponding default judgment condition is matched, and the multiple corresponding matching characteristic of cell access characteristic parameter is obtained
Value.
Step S230: and the multiple small by the corresponding matching characteristic value of the multiple cell access characteristic parameter
Access characteristic parameter corresponding weighting coefficient in area's is multiplied, and obtains multiple product values.
As a kind of mode, when access characteristic parameter is divided into the insensitive cell access characteristic parameter of difference and difference
When sensitive cell access characteristic parameter, it is assumed that the mismatch degree of the insensitive characteristic parameter of difference be a1, a2 ..., am, weighting
Coefficient be p1, p2 ..., pm, the mismatch degree of difference sensitive features parameter be B1, B2 ..., Bn, weighting coefficient Q1,
Q2 ..., Qn, then the pseudo-base station parameter R of the final cell are as follows:
Step S240: the multiple product value is summed, and obtains the corresponding pseudo-base station parameter in the base station.
Step S250: the pseudo-base station parameter is compared with parameter preset, when comparison result meets preset condition,
It is pseudo-base station by the identification of base stations.
After it is pseudo-base station that mobile terminal is by identification of base stations, if can be accessed without other cells, also it can choose
It resides in and has been identified as cell locating for the base station of pseudo-base station.
As a kind of mode, as shown in figure 4, the application further include:
Step S310: the mobile terminal is resident cell locating for the base station.

Completed in the radio band of mobile terminal cell locating for base station frequency sweep, down-going synchronous, obtain broadcast message and etc..
Step S320: judge mobile terminal whether successful execution communication service.
Step S330: if successful execution communication service when the mobile terminal is resident cell locating for the base station, obtain to
Characteristic parameter is adjusted, the characteristic parameter to be adjusted is corresponding matching characteristic value table in the multiple cell access characteristic parameter
Levy the parameter that the base station is pseudo-base station to be confirmed.
Wherein, communication service includes voice service or data service.
Step S340: the weighting coefficient corresponding to the characteristic parameter to be adjusted is reduced.
In this case, when reducing weighting coefficient, characteristic parameter to be adjusted can be subtracted to g1 or multiplied by coefficient g2,
Wherein 0 < g1, g2 < 1.
For example, mobile terminal, during identifying base station, there are two the decision value of cell access characteristic parameter is non-zero for base station
(i.e. it is pseudo-base station to be confirmed that the matching characteristic value of this two cell access characteristic parameters, which characterizes the base station), two cells connect
Entering characteristic parameter is respectively: position area LAC information and minimum reception level.The actual value of position area LAC is 0, presets judgement item
Part is (1,2,3 ..., 65534)；The actual value that minimum receives level is -43, presets judgment condition Shi≤- 49.Such as scheme to move
Terminal re-recognizes the cell for normal base station cell in the cell successful execution voice service.Then assume g1=0.05,
KG=0.9, then position area LAC information and the minimum weighting coefficient for receiving level, i.e., be adjusted to by GM=1-0.05=0.95
0.95.Wherein, KG is adjustment threshold value.
Step S350: judge whether be not less than tune after the weighting coefficient corresponding to the characteristic parameter to be adjusted reduces
Whole threshold value.
Step S360: if being less than the adjustment threshold value, the actual value of the characteristic parameter to be adjusted is added to corresponding
In default judgment condition, the corresponding weighting coefficient of the characteristic parameter to be adjusted is restored to the initial of the adjustment threshold value
Value, the initial value are not less than the adjustment threshold value.
For example, mobile terminal, during identifying base station, there are two the decision value of cell access characteristic parameter is non-zero for base station
(i.e. it is pseudo-base station to be confirmed that the matching characteristic value of this two cell access characteristic parameters, which characterizes the base station), two cells connect
Enter characteristic parameter difference still: position area LAC information and minimum reception level.The actual value of position area LAC information is 0, minimum
The actual value for receiving level is -47.Mobile terminal is after the cell successful execution data service, in g1=0.06, KG=0.95
In the case where, GM=1-0.06=0.94, i.e. GM < KG.Start default judgment condition amendment, default the sentencing of position area LAC information
Certainly condition be adjusted to (0,1,2,3 ..., 65534), minimum receives the default judgment condition Tiao Zheng Wei≤- 43 of level, simultaneously plus
Weight coefficient GM becomes 1.Wherein, GM is weight coefficient.
A kind of method identifying pseudo-base station provided by the present application, by using to the actual values of multiple cell access parameters into
The analysis of row comprehensive and quantitative, more accurate identifies whether base station is pseudo-base station, improves the accuracy of pseudo-base station identification.And
And when it is resident be identified as cell locating for the base station of pseudo-base station when, after successful execution communication service, cell can be accessed again
