Abstract:
1. A method of deciding execution of handover of a mobile terminal from a source base station to a target base station in a wireless communication system, the method comprising: deciding, by a source base station that currently serves the mobile terminal, a target base station for handover of the mobile terminal; deciding, by the source base station, a hysteresis value for determining a time point of executing the handover; determining, by the source base station, whether a difference between a first received signal strength of a signal from the target base station to the mobile terminal and a second received signal strength of a signal from the source base station to the mobile terminal is continuously maintained to be equal to or greater than the hysteresis value for a predetermined time duration; and deciding, by the source base station, to execute the handover when the difference between the first received signal strength and the second received signal strength is continuously maintained to be equal to or greater than the hysteresis value for the predetermined time duration, wherein the deciding, by the source base station, a hysteresis value includes deciding the hysteresis value based on traffic loads of the source base station and the target base station, a movement speed of the mobile terminal, and traffic distribution in the mobile terminal.
