  To ensure the maximum utilization of the limited bandwidth resources and
improved quality of service (QoS) is the key issue for wireless communication
networks. Excessive call blocking is a constraint to attain the desired QoS. In
cellular network, as the traffic arrival rate increases, call blocking
probability (CBP) increases considerably. Paying profound concern, we proposed
a scheme that reduces the call blocking probability with approximately steady
call dropping probability (CDP). Our proposed scheme also introduces the
acceptance factor in specific guard channel where originating calls get access
according to the acceptance factor. The analytical performance proves better
performance than the conventional new-call bounding scheme in case of higher
and lower traffic arrival rate.
