Methods to sustain cellular channel availability in high traffic location

This paper concerns GSM cellular network where congestion problem is common resulting in insufficient capacity of high interference level. One of the most efficient techniques is cell breathing where the coverage will shrink when more users are supported. Further, we propose a new approach that is intersystem handoff for congested network where the handoff takes place from one network to another network. It is analyzed that proposed approach Intersystem handoff in congested area is approximately 89% more cost effective than cell breathing approach.
