Abstract

Handover is essential for seamless communication since subscribers move from cell to cell. This paper proposes an efficient handover decision based on user mobility to suppress the ping-pong effect. By using GPS positioning, the proposed algorithm adds a hysteresis parameter associated with distance between the mobile and surrounding base stations and a hysteresis parameter associated with the mobile heading direction in Event 1A and 1C. The performance was verified by applying the proposed method to a WCDMA system in urban Taipei city. The result shows that by using the proposed algorithm, handover number and mean active set number are decreased compared to the traditional algorithm
