Power Congestion: RRM makes an admission algorithm decision. Downlinkadmission decision occurs. Therefore, RRM starts RRC establishment rejection.This often occurs when heavy network load leads to congestion. Further, we maystart Cell Traffic Load Analysis of related query, pay much attention to themaximum RTWP and the maximum TCP of this cell and make sure whether thereis uplink congestion or downlink congestion. For congestion, we may checkwhether a threshold is properly set and judge whether there is any radiointerference, whether expansion is necessary.
