Based on above-mentioned terminal hardware structure, each embodiment of the inventive method is proposed.

Embodiment one

Embodiments provide the recognition methods of a kind of pseudo-base station, as in figure 2 it is shown, the method may include that

S101, when carrying out network insertion, obtain at least one systematic parameter that at least one first base station is corresponding, this is extremely A few systematic parameter is for characterizing the messaging parameter judging whether to network insertion.

It should be noted that based on the communication construction shown in Fig. 3, terminal can communicate with base station, when terminal is carried out When community selection or re-selecting cell, this terminal can be searched for by the network frequency that base station carries out can use from core net, obtains Available network frequency point information is informed to terminal, and this terminal just selects the frequency that signal is strong to carry out from these network frequency point information Access, to realize network service.The recognition methods of a kind of pseudo-base station that the embodiment of the present invention provides is to be applied to terminal carrying out Community selects or in the case of gravity treatment, owing to being likely encountered the interference of the stronger network frequency of the signal of the camouflage of pseudo-base station, leads Cause terminal is connected to the method for the identification pseudo-base station of the scene proposition of pseudo-base station.

Broadcast system message that is concrete, that can continue due to base station, when terminal is needing to carry out the situation of network insertion Time lower, this terminal can obtain the system message of base station from the broadcast received.

It should be noted that the base station that can communicate with terminal in embodiments of the present invention is referred to as the first base station, Base station owing to communicating with this terminal can have multiple, therefore, and can communicate with terminal in the embodiment of the present invention The first base station can have at least one, the number of the concrete base station that can communicate with terminal is according to actual communication feelings Condition determines, the embodiment of the present invention is not restricted.

It is understood that terminal can receive the system message of the first base station broadcast in time, it is also possible to Receive or listening broadcast, such as, periodically receive broadcast or receive again when carrying out cell searching.Terminal can be according to connecing The broadcast received, finds the first base station, it is possible to determine whether to access the first base station by selection.One terminal may connect Receiving the broadcast that multiple first base station sends, and may select from the community that suitable first base station is corresponding, such as signal quality is relatively Good the first base station etc., thus reside in the community that this first base station is corresponding.

Therefore, when terminal wants to carry out network insertion, this terminal can obtain from least one the first base station corresponding At least one system message is resolved at least one systematic parameter that this at least one first base station is corresponding, say, that every The all corresponding system message in individual first base station, each system message can a corresponding systematic parameter.The present invention implements At least one systematic parameter in example judges whether to the messaging parameter of network insertion for characterizing.

S102, judging whether there is the target system parameters meeting preset rules at least one systematic parameter, this is preset Rule is for combination based on each parameter in systematic parameter, it is determined that whether there is pseudo-base station in this at least one systematic parameter Systematic parameter.

After terminal obtains at least one systematic parameter that at least one first base station is corresponding, this terminal just can will obtain At least one systematic parameter carry out mating or contrasting with preset rules, whether to judge in these at least one systematic parameters There is target system parameters, say, that terminal can be according to what preset rules was judged to meet from least one systematic parameter System parameter, the systematic parameter meeting preset rules that will determine that out in the embodiment of the present invention is referred to as target system parameters.

It should be noted that the preset rules in the embodiment of the present invention judges that at least one systematic parameter be not It it is the rule of the systematic parameter (target system parameters) that there is pseudo-base station.Concrete, preset rules is the system ginseng that base station is corresponding The combination of the parameter in number.

Optionally, the systematic parameter that each first base station in the embodiment of the present invention is corresponding may include that access is permitted protecting Stay block number (bs_ag_blks_res), CCCH configuration parameter (ccch_conf), the cycle (t_3212_ of location updating Timeout), community minimum accesses level value (rxlev_access_min) and cell reselection offset parameter (CELL_ RESELECT_OFFSET).Wherein, access allowance reserved block number, CCCH configuration parameter, the cycle of location updating are Controlling channel relevant parameter, it is cell selection parameters that community minimum accesses level, and cell reselection offset parameter is cell reselection ginseng Number.

It should be noted that in the setting of preset rules, i.e. systematic parameter parameter combination be by empirical value or experiment Value is determined.

It should be noted that owing to pseudo-base station wants terminal to access it is necessary to pretend the systematic parameter of oneself, such as signal strong Spending stronger etc., as shown in table 1, pseudo-base station is as follows with the contrast of the systematic parameter of real base station:

Table 1

As shown in Table 1, pseudo-base station and the systematic parameter of real base station be have camouflage vestige can be target-seeking.Therefore, the present invention is real Execute the preset rules in example to be formed by the parameter value combination of following systematic parameter:

1, bs_ag_blks_res=2；

2, ccch_conf=1；

3, t_3212_timeout=1；

4, rxlev_access_min=0；

5, CELL_RESELECT_OFFSET=63.

It should be noted that pseudo-base station decisional table can be made up of the combination of systematic parameter, due in the embodiment of the present invention Preset rules time systematic parameter in a part of parameter combination, therefore, the preset rules in the embodiment of the present invention can be from puppet Base station decisional table (table 2) is determined.

Table 2

Wherein, in table 2, the court verdict of pseudo-base station is as follows: 1 is pseudo-base station；2 is doubtful pseudo-base station；0 is real base station.

It should be noted that to be the probability of pseudo-base station big in the first base station corresponding to systematic parameter that court verdict is 2, but Being not necessarily, therefore, the preferably court verdict that the recognition methods of the pseudo-base station in the embodiment of the present invention identifies is 1 The first base station that systematic parameter is corresponding.Therefore, under the preset rules in the embodiment of the present invention can be according in table, judgement meets State the condition of situation:

(1,2,3) (4,5 regardless of whether meet) simultaneously meets for pseudo-base station；

(1,2,5) (3,4 regardless of whether meet) simultaneously meets for pseudo-base station；

(2,3,5) (1,4 regardless of whether meet) simultaneously meets for pseudo-base station；

(1,3,4,5) (2 regardless of whether meet) simultaneously meets for pseudo-base station.

Therefore, starting up of terminal is searched net, location updating, community weight by the recognition methods of the pseudo-base station that the embodiment of the present invention provides Choosing etc. all there is no impact, does not affect the regular traffic function of terminal.

S103, when judging to exist target system parameters, by the first corresponding for this target system parameters identification of base stations be Pseudo-base station.

Due to preset rules be the first base station corresponding to decision-making system parameter be whether the condition of pseudo-base station, therefore, terminal Judge whether at least one systematic parameter exists in the presence of the result of the target system parameters meeting preset rules is, i.e. work as end When end judges to there is, at least one systematic parameter, the target system parameters meeting preset rules, the mesh that this terminal will determine that out The first identification of base stations marking parameter corresponding is pseudo-base station.

It should be noted that terminal can get the systematic parameter of at least one the first base station, each first base station A corresponding systematic parameter, therefore, the number in this terminal judges target system parameters may have multiple, concrete, is basis Actual court verdict is learnt.

Concrete, a systematic parameter is combined by terminal with each parameter in preset rules mates；When one is System parameter and at least one parameter combination is time the match is successful, and terminal determines that this systematic parameter is the target meeting preset rules In systematic parameter one；Whether the remaining system parameter that terminal continues to judge at least one systematic parameter is goal systems ginseng Number, until determining whole target system parameters.

Exemplary, it is assumed that the 1, second base station, the first base station 2 that terminal gets and the systematic parameter of the 3rd base station 3, and Terminal judges goes out the parameter combination 1234 that the systematic parameter of the first base station 1 correspondence meets in table 2, the system of the second base station 2 correspondence Parameter meets the parameter combination 234 in table 2, and the systematic parameter of the first base station 3 correspondence meets the parameter combination 134 in table 2, then should Terminal judges goes out the first base station 2 and meets preset rules, and therefore, it is mesh that this terminal judges goes out the systematic parameter of the first base station 1 correspondence Mark system parameter, and then the first corresponding for this target system parameters base station 1 is identified as pseudo-base station by this terminal.

S104, when judging not exist target system parameters, utilize location updating authentication process identification at least one Whether the first base station exists pseudo-base station.

Due to preset rules be the first base station corresponding to decision-making system parameter be whether the condition of pseudo-base station, therefore, terminal Judge whether at least one systematic parameter exists the result of the target system parameters meeting preset rules in the presence of not, i.e. when Terminal judges goes out when there is not, at least one systematic parameter, the target system parameters meeting preset rules, and this terminal can be further The recognition methods of pseudo-base station of other modes of carrying out, then, terminal utilize location updating authentication process identification at least one Whether the first base station exists pseudo-base station.

Concrete, terminal is at least one the first more newly requested message of base station launch position；Receive at least one first base At least one the location updating response message of correspondence of standing；When at least one location updating response message is for accepting location updating message Time, it is pseudo-base station by accepting the first identification of base stations corresponding to location updating message.

On the basis of framework as shown in Figure 4, first, the more newly requested message of terminal launch position, the first base station receives this end By core net initiation authentication request to terminal after the location update request message of end, this terminal is by the identity identification information of user Pretend, become the specific information of a non-user, and the specific information of this non-user is reported to base station；Work as base Station determines the specific information of terminal feedback when being error message, and the position updating request of this terminal can be refused in real base station, The location updating response message that i.e. first base station sends is refusal location updating message, then, the real base station mirror to terminal Weigh unsuccessfully；Pseudo-base station then no matter the Authentication Response of terminal feedback be that what information all can the position updating request of receiving terminal disappear Breath, thus feed back to one, terminal and accept location updating message, therefore, this terminal can be by the position of the first base station of acquisition Update response message and identify the true and false of at least one the first base station.

The recognition methods of a kind of pseudo-base station that the embodiment of the present invention is provided, by when carrying out network insertion, obtains extremely At least one systematic parameter that few first base station is corresponding, this at least one systematic parameter judges whether to net for sign The messaging parameter that network accesses；Judge whether at least one systematic parameter exists the target system parameters meeting preset rules, should Preset rules is used for combination based on each parameter in systematic parameter, it is determined that whether there is pseudo-base station at least one systematic parameter Systematic parameter；When judging to exist target system parameters, it is pseudo-base by the first corresponding for target system parameters identification of base stations Stand；When judging not exist target system parameters, utilize at least one first base station of authentication process identification of location updating Whether there is pseudo-base station.When using above-mentioned technic relization scheme, owing to terminal can identify pseudo-base with coupling system parameter and authentication The method stood combines, and before terminal is in cell reselection and during the different scene of location updating, can use and different identify pseudo-base The method stood, thus improve motility and the suitability identifying pseudo-base station.

S203, determine access permit the first predetermined threshold value of reserved block number, CCCH configuration parameter second pre- If the 3rd predetermined threshold value in the cycle of threshold value, location updating, community minimum access the 4th predetermined threshold value and the community weight of level value Select the 5th predetermined threshold value of offset parameter.

S204, the first predetermined threshold value, the second predetermined threshold value, the 3rd predetermined threshold value, the 4th predetermined threshold value and the 5th are preset Threshold value carries out combination in any, forms the combination of N number of parameter, and wherein, N is more than or equal to 1.

S205, determining that M parameter group is combined into preset rules from N number of parameter combines, wherein, M is more than or equal to 1 and little In equal to N.

Table 1

As shown in Table 1, pseudo-base station and the systematic parameter of real base station be have camouflage vestige can be target-seeking.Therefore, terminal determines Access and permit the first predetermined threshold value of reserved block number, the second predetermined threshold value of CCCH configuration parameter, location updating It is the 5th pre-that 3rd predetermined threshold value in cycle, community minimum access the 4th predetermined threshold value of level value and cell reselection offset parameter If threshold value can be such that

2, ccch_conf=1；

3, t_3212_timeout=1；

4, rxlev_access_min=0；

5, CELL_RESELECT_OFFSET=63.

It should be noted that pseudo-base station decisional table can be combined into by the parameter group in systematic parameter, terminal is pre-by first If threshold value, the second predetermined threshold value, the 3rd predetermined threshold value, the 4th predetermined threshold value and the 5th predetermined threshold value carry out combination in any, form N The combination of individual parameter is as shown in the parameter in table 2 combines, due in systematic parameter during preset rules in the embodiment of the present invention Partial parameters combines M parameter combination, and therefore, the preset rules in the embodiment of the present invention can be from pseudo-base station decisional table (table 2) In determine.

Table 2

It should be noted that to be the probability of pseudo-base station big in the first base station corresponding to systematic parameter that court verdict is 2, but Being not necessarily, therefore, the preferably court verdict that the recognition methods of the pseudo-base station in the embodiment of the present invention identifies is 1 The first base station that systematic parameter is corresponding.Therefore, the preset rules in the embodiment of the present invention can be according in table judgement meet with The situation of lower M parameter combination:

S206, by a systematic parameter with in preset rules each parameter combine mate.
