The distance between stand with target terminal user, distance is more remote, and source signal intensity is weaker, and distance is nearer, and source signal intensity is stronger.?
During the corresponding signal quality in two base stations of consideration, the corresponding source signal intensity in the base station had both been considered, in addition it is also necessary to which consideration is according to average
The channel estimation report that drop rate or outage are generated, therefore, it can to consider source signal intensity and average drop rate or
The channel estimation report that outage is generated.
That is, obtain the corresponding source signal intensity in base station that is currently connected into of target terminal user and adjacent base station is corresponding
(the destination channel intensity is similar with source signal intensity, and corresponding under not connected base station is destination channel for destination channel intensity
Intensity)；Also, according to default weight coefficient, channel estimation is reported and source signal intensity/destination channel intensity carry out plus
Power, finally respectively obtains corresponding the first evaluation of estimate for evaluating signal quality in base station that target terminal user is currently connected into, and
Corresponding the second evaluation of estimate for evaluating signal quality of adjacent base station, also, according to the first evaluation of estimate and the size of the second evaluation of estimate
To determine whether target terminal user needs to carry out switching or the gravity treatment of base station.
For example, when the first evaluation of estimate is better than the second evaluation of estimate, target terminal user need not carry out the switching of base station or weight
Choosing, when the second evaluation of estimate is better than the first evaluation of estimate, the base station being currently connected into is switched to second and comments by target terminal user needs

It is worth when exceeding default duration parameters with the difference of first evaluation of estimate more than the duration of threshold value, determines by described affiliated
Base station switches or reselects to the adjacent base station.
That is, when the signal quality of base station is considered, necessary not only for the signal instruction of consideration moment, in addition it is also necessary to examine
Consider the good and bad duration of signal quality, for example, only compare the in corresponding second evaluation of estimate of target BS for preparing to switch
In the case that the one evaluation of estimate more excellent duration exceedes default duration parameters, switching or the gravity treatment of base station is just carried out.Enter one
Step, in another embodiment, in addition it is also necessary to consider difference of second evaluation of estimate more than the first evaluation of estimate more than default threshold value
