Performance of RSCP-triggered and Ec/No-triggered inter-frequency handover criteria for UTRA

Abstract

This paper compares two different handover criteria in WCDMA through simulations. The simulations are carried out in a WCDMA HCS system where the hexagonal macro and the Manhattan-like micro layer use different frequencies. Two possible handover triggering schemes i.e. CPICH RSCP and CPICH Ec/No, are compared under the same simulation environments and various cell loads. The handover performance is observed in terms of system efficiency including signalling and QoS such as call dropping probability and call blocking probability.
