Claim 4:
5. A device for optimizing unbalanced loads covered by a same network, comprising:
a judgment module, configured to determine whether loads of cells covered by a same network are balanced;
a first determination module, configured to determine, if the judgment module determines that the loads of the cells covered by the same network are unbalanced, a cell with a highest network load rate and a cell with a lowest network load rate in the cells covered by the same network;
a second determination module, configured to determine a target offset parameter corresponding to a predetermined index according to a timing advance and the number of sampling points of the cell with the highest network load rate and a timing advance and the number of sampling points of the cell with the lowest network load rate, wherein the predetermined index is an index to which a user equipment refers when selecting a cell; and
an adjustment module, configured to adjust a load of the cell with the highest network load rate and a load of the cell with the lowest network load rate based on the target offset parameter, to make the number of the sampling points of the cell with the highest network load rate be less than the number of the sampling points of the cell with the lowest network load rate,
wherein the second determination module comprises:
a judgment unit, configured to determine whether a distribution of the timing advance of the cell with the highest network load rate is similar to a distribution of the timing advance of the cell with the lowest network load rate; and
a determination unit, configured to: adjust, if the judgment unit determines that the distribution of the timing advance of the cell with the highest network load rate is not similar to the distribution of the timing advance of the cell with the lowest network load rate, an antenna down-tilt angle of the cell with the lowest network load rate to be the same as an antenna down-tilt angle of the cell with the highest network load rate, and determine the target offset parameter corresponding to the predetermined index; and directly determine, if the judgment unit determines that the distribution of the timing advance of the cell with the highest network load rate is similar to the distribution of the timing advance of the cell with the lowest network load rate, the target offset parameter corresponding to the predetermined index,

wherein for determining the target offset parameter corresponding to the predetermined index, the determination unit is configured to:
adjust an initial offset parameter to acquire an intermediate offset parameter, wherein the intermediate offset parameter is a minimum integer capable of making a difference between a value of the predetermined index of the cell with the highest network load rate and the intermediate offset parameter be less than a value of the predetermined index of the cell with the lowest network load rate;
determine, if the value of the predetermined index of the cell with the highest network load rate is reduced by the intermediate offset parameter, whether the number of the sampling points of the cell with the highest network load rate is greater than the number of the sampling points of the cell with the lowest network load rate;
increase, if it is determined that the number of the sampling points of the cell with the highest network load rate is greater than the number of the sampling points of the cell with the lowest network load rate in a case that the value of the predetermined index of the cell with the highest network load rate is reduced by the intermediate offset parameter, the intermediate offset parameter by a predetermined step and determine the increased intermediate offset parameter as a new intermediate offset parameter, and perform the operation of determining, if the value of the predetermined index of the cell with the highest network load rate is reduced by the intermediate offset parameter, whether the number of the sampling points of the cell with the highest network load rate is greater than the number of the sampling points of the cell with the lowest network load rate; and
determine, if it is determined that the number of the sampling points of the cell with the highest network load rate is not greater than the number of the sampling points of the cell with the lowest network load rate in a case that the value of the predetermined index of the cell with the highest network load rate is reduced by the intermediate offset parameter, a newest intermediate offset parameter as the target offset parameter.
