Patent ID: 8812003

Claim:
A method for avoiding the occurrence of ping-pong handovers by a UE in the connected state between adjacent cells, comprising: presetting an adjusting determination parameter Δ in an evolved Node B (eNB); during a statistics period, the evolved Node B (eNB) in a long term evolution (LTE) system serving cell determining the ping-pong handovers between the serving cell and an adjacent cell occurred when said eNB determines a user equipment (UE) has been handed over between the serving cell of the eNB and the adjacent cell continuously for at least three times within a duration of a ping-pong judging threshold value; wherein said eNB considers each three times that the UE is handed over between the serving cell of the eNB and the adjacent cell continuously within the duration of the ping-pong judging threshold value as one ping-pong handover; at the end of the statistics period, the eNB increasing a value of a handover control parameter of the serving cell of the eNB when the eNB judges that the times of the serving cell of the eNB being the source cell in the second handover of all ping-pong handovers is greater than a sum of the times of the serving cell of the eNB being the target cell in the second handover of all ping-pong handovers and Δ, or when the eNB judges that the absolute value of the difference between the times of the serving cell of the eNB being the target cell and the times of the serving cell of the eNB being the source cell in the second handover of all ping-pong handovers is less than Δ.
