It is removed in the banned list of base station cell.
Specifically, in base station cell after being removed in the banned list of base station cell, base station cell can be carried out again random
Access procedure.It, can be first in resident base station when mobile terminal, which is login state in some operator, to do business
Initiating random access procedure in cell, if 6 failures were initiated, and radio resource control layer would be according to the SINR that physical layer reports
It is no to preset in SNR ranges, for example, default SNR ranges can be the range of -10db to -40db, if not at this
Then the base station cell is put into the banned list of base station cell in default SNR ranges.Rrc layer request simultaneously, which starts, to be forbidden
The timer preset time of the base station cell, wherein in the present embodiment, preset time can be, but not limited to 15 minutes, such as
Preset time can also be the time of other durations such as 5 minutes, 10 minutes and 20 minutes.Radio resource control layer initiates other base station
Cell reselection, if can be if gravity treatment, i.e. mobile terminal net state can be being fallen, then will without other suitable base station cell
No service (NO SERVICE) is reported, after NAS layers of Non-Access Stratum receives no service, will initiate to search net, it is suitable to find again
Cell it is resident.Since the base station cell is prohibited access, so will not be resident on the base station cell again, 15 points at that time
After the timer expiry of clock, radio resource control layer gets rid of the cell inside the banned list of base station cell, so that the base
Cell of standing can carry out random access procedure again.
