    • A method for avoiding cell pingpong reselection is disclosed in the present invention, which comprises: cells which are able to be candidate serving cells are selected, according to an S criteria, from current serving cells and adjacent non-serving cells; an optimal cell is determined, according to an R criteria, from the candidate serving cells; if the optimal cell is not the current serving cell, it is determined that whether the signal intensity and the signal quality of the optimal cell are greater than or equal to reselection thresholds, wherein the reselection thresholds are greater than the minimum serving thresholds of the serving cell; and in the condition that the signal intensity and the signal quality of the optimal cell are greater than or equal to reselection thresholds, the cell reselection is initiated. The embodiments of the present invention also provide a corresponding terminal. Since the reselection thresholds of the cell reselection are increased in the solution of the present invention, the cells with good signal intensity and bad signal quality or the cells with bad signal intensity and good signal quality will not be within the candidate range of the reselection cells, and thus the cell pingpong reselection is avoided to occur frequently effectively.
    • 本发明公开了一种避免小区乒乓重选的方法,其特征在于包括:根据S标准从当前服务小区和相邻的非服务小区中选择能够成为候选服务小区的小区; 根据R标准从候选服务小区确定最佳小区; 如果最佳小区不是当前服务小区,则确定最佳小区的信号强度和信号质量是否大于或等于重选阈值,其中重选阈值大于服务小区的最小服务阈值 细胞; 并且在最佳小区的信号强度和信号质量大于或等于重选阈值的条件下,启动小区重选。 本发明的实施例还提供相应的终端。 由于在本发明的解决方案中小区重选的重选阈值增加,所以具有良好的信号强度和不良信号质量的小区或具有差的信号强度和良好信号质量的小区将不在候选小区的候选范围内 ,因此可以有效地避免细胞乒乓重选。
