Step 201: when detecting current area overload, selects maximum signal value from the adjacent cell signal strength values that terminal is measured;
It should be noted that, so-called " signal strength values " can be Reference Signal Received Quality value RSRQ or Reference Signal Received Power value RSRP, also can be other parameter values of the signal strength signal intensity that can reflect community.
Such as: the signal strength values that terminal 1-20 selects adjacent cell 1 is respectively maximum, the signal strength values that terminal 20-40 selects adjacent cell 2 is respectively maximum, the signal strength values that terminal 40-60 selects adjacent cell 3 is big-and-middle, and terminal 60-80 selects the signal strength values of adjacent cell 4 big-and-middle respectively.
