To guarantee rationally switching, base station can be adjacent area frequency/specific biasing (Ofn/Ocn) of cell setting, or be clothes Specific biasing (Ofs/Ocs) is arranged in frequency/cell of being engaged in, to help terminal to be switched to best cell.

By taking A3 event as an example, A3 event are as follows: adjacent cell is better than serving cell, this event occurs to be used to determine that UE is It is no to be switched to adjacent cell, when adjacent cell than serving cell quality be higher than a thresholding (Neighbour > Serving+Offset), The switching between interior/frequency frequently can just be triggered.The decision threshold of A3 event is as follows:

Event entry condition: Mn+Ofn+Ocn-Hys > Ms+Ofs+Ocs+Off

Event leaves condition: Mn+Ofn+Ocn+Hys < Ms+Ofs+Ocs+Off

Wherein:

Mn: the measurement result of adjacent cell does not consider to calculate any biasing；

Ofn: the adjacent area frequency specifically biases；

Ocn: the Cell Individual Offset of the adjacent area, while if being not neighbor cell configuration, it is set as 0；

Ms: the measurement result of the serving cell under any biasing is not calculated；

Ofs: frequency specifically biases on service frequency；

Ocs: the Cell Individual Offset of serving cell is set as 0 if do not configured for serving cell；

Hys: the lag parameter of the event；

Off: for the offset parameter of the event；

In the prior art, when configuring measurement parameter for UE, there is no the preferences for considering UE for base station, such as to data speed Rate/multi-connection preference.

It can guarantee UE higher data speed to make terminal not switch on the carrier wave for not supporting dual link or be switched to as far as possible On the carrier wave of rate, base station can be the lesser Ofn and/or Ocn value of carrier wave setting for not supporting dual link, or be server carrier Ofs and/or Ocs is set, or biggish Hys and/or Off is set for current event.In order to which assistant base station does reasonable measurement Parameter configuration is reported, UE needs to report it to high data rate/dual link preference.
