the processor is further configured to determine a first distance between the UE and the first base station according to the cell location information and the current location information of the UE; determining a base station to be switched by the UE according to the first distance and a second distance, wherein the second distance is the distance between the UE and the second base station, and the second base station is a base station which is currently connected with the UE; or, according to the first distance and a second distance, synchronously switching the UE between the first base station and a second base station, where the second distance is a distance between the UE and the second base station, and the second base station is a base station currently establishing connection with the UE.
9. The base station of claim 8, wherein the cell location information further comprises location information of a third cell, the third cell being a cell to which the third base station belongs, the third base station being a base station to which the UE was connected before connecting to the first base station.
10. The base station of claim 8 or 9, wherein the processor is configured to optimize mobility of the UE according to the cell location information.
11. The base station of claim 10, wherein the cell location information comprises at least one of a location coordinate of the first cell, an identity of the first cell, a range of the first cell, and a time of the UE at the first cell, a location coordinate of a third cell, an identity of the third cell, a range of the third cell, and a time of the UE at the third cell.
12. The base station of claim 11, wherein the processor is further configured to determine the UE movement path information according to the cell location information.
13. The base station of claim 11 or 12, wherein the position coordinates of the first cell are first antenna position coordinates of the first cell, and wherein the first antenna is an antenna to which a first base station of the first cell is connected.
14. The base station of claim 11 or 12, wherein the position coordinate of the third cell is a third antenna position coordinate of the third cell, and wherein the third antenna is an antenna to which a third base station of the third cell is connected.
