This paper presents a method of reducing handoff delay and minimising handoff failure probability using available technology, without compromising bandwidth efficiency considerably, by altering and streamlining the functionality and task division of the contemporary handoff technique. This would result in fewer call failures and in congestion-free networks. There is a need for reduced handoff time in Next Generation Wireless Systems (NGWS), since lower handoff periods would result in higher data efficiency and fewer handoff failures. This would cause fewer data packet losses resulting in higher QoS, which is a primary facet of NGWS networks. Moreover, 4G networks integrate certain microcellular networks, like IEEE 802.11, which requires quicker handoff because number of handoffs becomes exponentially higher and cell size dramatically drops with respect to macrocellular networks.
