Load balance is a key technology in future heterogeneous wireless networks due to its merits like improving resource utilization, enlarging system capacity and providing QoS for users. This paper presents a load balancing scheme which is composed of QoS-based and load-related admission control and dynamic vertical handover. The scheme can provide better QoS and jointly optimize resource utilization...
Facing the different wireless access networks, this paper has proposed several novel interworking AAA architectures among the 3GPP, WiMax and hotspot wireless LANs. In these architectures, a new entity named standby 3GPP AAA server is defined to cope with the single point failure. Moreover, based on the proposed interworking AAA architectures, a hierarchy AAA scheme is proposed. As a result, the simulation...
