A Smart Handoff Procedure in 4G Networks

For the next generation mobile communication systems, all IP packet networks instead of the legacy networks that are mixture of circuit and packet switching services have been studied to guarantee the high-speed data transfer rate even in the high-speed mobile environments. In the packet networks, the rate that mobile users are serviced varies according to the number of users in a single cell. Moreover, as the adaptive modulation and coding adjusts the data rate in terms of channel conditions, the service quality are dominated by two components; service rate by cell load and data rate by channel conditions. Therefore, we propose the smart handoff procedure considering both the service rate and the data rate for the service quality in the next generation communication systems.
