Wireless correspondence is confronting the quickest progressive changes in innovation. The control plane 4G speeds are intended to surpass that of 3G. Current 3G speeds have an upper top at 14 Mbps downlink and 5.8Mbps uplink. On the off chance that we accomplish the speed of up to 100 Mbps for a moving client and 1 Gbps for stationary client is achieved, it is named 4G advancements. Seamless roaming and versatility the executives are the premier difficulties before heterogeneous 4G remote systems. The goal of this work is to discover the simple and helpful strategy for vertical handoff which spread all the vital parameters required for handoff with a rearranged way utilizing layered methodology so both programmed and client explicit handovers are conceivable. Here we propose the GPA strategy to be created on the three layered stage to give a straightforward design which performs both kind of handovers considering more extensive scope of elements for basic leadership.
