3rd embodiment
Shown in Figure 18, third embodiment of the invention provides a kind of method of cell switching, applied to base station, including such as
Lower step：
Step 301：Obtain the channel occupancy information of at least one first object base station；
Step 302：Receive user equipment to report at least one first object base station with receive reference signal phase
The first measured value closed；
Step 303：According to the channel occupancy information and first measured value, the switching mesh of the user equipment is determined
Mark base station.
The method of the cell switching of third embodiment of the invention, believes by using the channel occupancy of the adjacent base station got
Breath switches over assessment to UE, can ensure that UE is switched to the idle base station of a channel occupancy, improve the machine of UE receiving and transmitting signals
Meeting, avoid compared with long time delay.
Wherein, the method that channel occupancy information is obtained in step 301 can be no longer superfluous herein referring specifically to first embodiment
State.
And first measured value related to receiving reference signal in step 302 is, for example, Reference Signal Received Power measurement
Value or Reference Signal Received Quality measured value, the present invention are not limited.
In the specific embodiment of the invention, this determines UE switching target base according to channel occupancy information and the first measured value
Stand at least to be realized using the following two kinds mode：
Mode one
In mode once, base station selects the first measured value more than or equal to the first object base station of the first predetermined threshold value first
UE handover-target base station Candidate Set is formed, then according to the channel occupancy information of acquisition, from the handover-target base station Candidate Set
Handover-target base station of the most idle first object base station of middle selection channel occupancy as UE.
Wherein, first predetermined threshold value is pre-set.Also, if the first measured value of a certain first object base station
More than or equal to first predetermined threshold value, mean that the signal of the first object base station is more excellent, can be as the switching target of candidate
Base station.
Mode two
Under mode two, base station is first according to channel occupancy information and the first measured value, it is determined that each first object base station
Handover decisions reference index value, then select first object base station the cutting as UE that the handover decisions reference index value is maximum
Change target BS.
Wherein, the handover decisions reference index value is used for the changeable degree for representing corresponding first object base station.Specifically, the
The handover decisions reference index value of one target BS is bigger, and its changeable degree is higher, i.e. after UE is switched to the first object base station,
Receiving and transmitting signal can be more preferable.
And the handover decisions reference index of corresponding first object base station is determined according to channel occupancy information and the first measured value
The method of value is, for example,：
If it is directed to first object base station A, then, A handover decisions reference index value is：
A channel occupancy information is multiplied by the first preset value, and the second preset value is multiplied by plus A the first measured value.
Wherein, the first preset value and the second preset value are pre-set according to actual conditions, by channel occupancy information
Combined with the first measured value and assessment is switched over to first object base station.
Fourth embodiment
