Hybrid next generation mobile system analysis based on Internet applications

To address future demand for improved services the next generation mobile systems will be compatible and interoperable with IPv6 and with various access technologies such as 802. llx. Discussion in the literature is currently as to whether the recently developed High Speed Packet Access (HSPA) or the developing Long Term Evaluation (LTE) technology is appropriate for the next generation mobile system. However, the HSPA and the LTE technologies require enhancements to provide ubiquitous data services. Hybrid network interworking of 3G/WLAN is capable of supporting ubiquitous data services and improved data rates in WLAN hotspots. This paper provides the results of a performance analysis of two potential 3G/WLAN integration schemes: tight and loose coupling. Mobile IP is used as a mobility management scheme and EAP-AKA for common authentication.
