Analytical Performance Evaluation of Inter-System Handover

Abstract

In this paper, we analyze the behavior of inter-system handover between second generation (GSM) and third generation (UMTS) mobile radio systems. A mathematical model is proposed to evaluate the handover performance. The handover initiation algorithm is based on the absolute signal strength thresholds. The algorithm performs handover when the averaged signal strength from the serving base station drops below a given threshold and that from the candidate base station exceeds a preset threshold. Handover rate and handover initiation delay are used as performance metrics. Based on numerical results, threshold parameter settings are determined for optimum handover performance.

Indexing terms:

• Mobile radio systems
• Inter-system handover
• Wireless communication
• Received signal strength measurements
