It is required that and different characteristics pseudo-base station.Accumulated by long term data, can according to the variation tendency of different type pseudo-base station to Y,
P, T combination is adjusted, to adapt to the update of pseudo-base station.
Y：The priority of judgment condition, priority represent the pseudo-base station type distribution of this feature；Priority is higher, and representing should
The pseudo-base station of feature is more.
P：The weighted value of judgment condition, weighted value represent the conspicuousness of pseudo-base station this feature；Weighted value is bigger, represents pseudo- base
The conspicuousness of this feature of standing is stronger.
T：Decision threshold, decision threshold represent the Stringency of UE judgement pseudo-base stations, the smaller expression of T values, and judgment condition is got over
Strictly, it is found that the probability of pseudo-base station is higher, but judgment condition is smaller, it is understood that there may be erroneous judgement.
In specific deterministic process is carried out using judgment condition, including
1) GPRS Indicator (GPRS instructions)：When in system infomation type 3 without GPRS
Indicator fields, judgement are true, and P1 is effective, and otherwise judgement is invalid；
mnc_2：When MNC (mobile network code) is not belonging to { set A } in system infomation type 3, judgement
It is true, P2 is effective, and otherwise judgement is invalid；
3) T3212 (periodical location area renewal duration)：As T3212 in system infomation type 3<=Ta
When, judgement is true, and P3 is effective, and otherwise judgement is invalid；Ta is equal to the T3212 average values of all adjacent base station cells,
Ta=T3212NCELL1+T3212NCELL2...+T3212NCELLN/n；
4) rxlev_access_min (this cell minimum received signal level)：As system infomation type 3
Middle rxlev_access_min<During=Tb, judgement is true, and P4 is effective, and otherwise judgement is invalid；Tb is equal to all adjacent base station cells
Rxlev_access_min average values,
Tb=rxlev_access_minNCELL1+rxlev_access_minNCELL2...+rxle v_access_
minNCELLN/n；
5) CELL_RESELECT_OFFSET (cell reselection biasing)：When in system infomation type 3
CELL_RESELECT_OFFSET>During=Tc, judgement is true, and P4 is effective, and otherwise judgement is invalid；It is small that Tc is equal to all adjacent base stations
The CELL_RESELECT_OFFSET average values in area,
Tc=CELL_RESELECT_OFFSETNCELL1+CELL_RESELECT_OFFSETNCELL2 ...+CELL_
RESELECT_OFFSETNCELLn/n；
Table 2 is the priority and judgment condition table according to the present embodiment, as follows：
