Handoff Traffic Acceptance Criteria with QoS Guarantee for the CDMA 1xEV-DO RA System

摘要

In this article two new criteria for handoff traffic acceptance based on the received signal power and the buffer occupation percentage are proposed. The proposed criteria are evaluated in conjunction with the data schedulers Max C/I (Maximum Carrier Interference) and PF (Proportional Fair). The evaluation is carried out through HTTP source models and using QoS metrics such as the average packet delay, the throughput and the loss percentage in function of handoff traffic load. The results showed that depending on the chosen criterion, it is possible to assure the QoS of CDMA 1xEV-DO RA system and still to accept a good amount of handoff traffic.
