If the result after summation is greater than the second predetermined threshold value, then to determine described the first system base station, according to after predetermined manner adjustment, multiplexingly to upgrade to described second system base station; Described predetermined manner covers for reducing crossing of described the first system base station;
Wherein, described second predetermined threshold value is less than described first predetermined threshold value.
9. the device according to any one of claim 6-8, is characterized in that,
Described network architecture parameters value comprises: the station of high, the described the first system base station, station of described the first system base station is close;
Described network coverage parameter value comprises: the non-master telephone service accounting of described the first system base station, soft-switch proportion, overlapping coverage rate.
10. device according to claim 9, it is characterized in that, described determining unit is worth the first corresponding unavailable factor for determining with described network architecture parameters, and the second unavailable factor corresponding with described network coverage parameter value is specially, and described determining unit is used for:
The unavailable factor of the close correspondence in station of the first system base station described in high for the station of described the first system base station corresponding unavailable Summing Factor is weighted summation, the result after summation is determined the described first unavailable factor;
The unavailable factor corresponding to the unavailable factor corresponding for the non-master telephone service accounting of described the first system base station, described soft-switch proportion and the unavailable factor corresponding to described overlapping coverage rate are weighted summation, the result after summation is defined as the described second unavailable factor.
