Abstract
A method for detecting and reducing ping-pong handover effect of a cellular network is disclosed. The method provides a systematic way to determine which cell pairs of the network have high probability of suffering from the ping-pong handover effect. The method comprises collecting network traffic statistic data of multiple items, wherein each of the items corresponds to a state change of multiple mobile units within cells of the network; determining whether a plurality of criteria are met according to the network traffic statistic data; and detecting the ping-pong effect between the cells according to the result of the determining step. The method also comprises changing a handover parameter for the cells with the ping-pong handover effect.
