Abstract
Provided is a handoff processing method including measuring a moving speed of a mobile terminal; measuring a size of a data packet generated in an application layer; measuring quality of a data transmission channel of the mobile terminal; calculating a maximum handoff delay time based on a relation between the moving speed and the data packet's size; estimating a handoff occurrence time point, based on a relation between a variation of the quality of the data transmission channel and the quality of the data transmission channel; and calculating a packet size and a moving speed of the mobile terminal that can minimize a delay due to a handoff occurrence by taking account of a handoff delay time according to the size of the data packet generated in the application layer and a moving speed of the mobile terminal into consideration, and providing the calculated packet size and moving speed.
