This paper presents an advanced cell visiting probability estimator for more accurately reserving resources for an estimated time interval to neighbouring cells by exploiting key mobility parameters (speed, direction and distance). The call admission control strategy used allocates bandwidth more efficiently to provide consistent Quality of Service (QoS) guarantees for multimedia traffics. Concomitantly, to ensure continuity of on-going calls with better utilization of resources, bandwidth is borrowed from existing adaptive calls without affecting the minimum QoS guarantee. Simulation results prove that the new scheme offers substantial improvements over the recent existing schemes.
