    Abstract:

    Radio resource management is important aspect to investigate as part of the LTE-Advanced study.And FSHO is an important handover scheme in LTE-A. FSHO sorts the service to VoIP service and non-VoIP service. Non-VoIP service are transmitted by source eNodeB or target eNodeB. VoIP services are transmitted from both source eNodeB and target eNodeB. Compared to hard handover, FSHO increases the time delay and outage probability. In this paper, we propose an optimized fractional soft handover scheme based on FSHO. The main idea is to Multi-carrier Handover Method for VoIP. The theoretical analysis and simulation results show that the optimized proposed fractional soft handover not only attains the lowest handover outage probability but also improve the reliability of VoIP service.
