This paper focuses on the cellular structure of small cells for the high density of population and a handoff scheme especially designed for real-time and QoS guaranteed services between two heterogeneous networks. In case of inter-system handoff (ISHO), the time required to complete the handoff can vary and depends on the network structure. And also the transmission of additional signals can increase the probability of failure for ISHO. The proposed scheme significantly reduces the ISHO failure rate up to about 16% compared to the existing one. This can be accomplished by alleviating workloads of boundary base stations and distributing them to predetermined neighboring cells.
