In this paper, an adaptive threshold load balancing (ATLB) scheme is proposed for the joint load control (JOLDC) in the end-to-end reconfigurable system. The dynamic threshold based on heterogeneous load measurement is designed to adapt to varying load conditions for efficient resource utilization, while the network-initiated vertical handover (NIVHO) process is adopted for the timely control by exploiting the network-controlled reconfiguration management. Furthermore, considering terminal reconfigurability and the service variety, a multi-objective terminal selection algorithm is designed for NIVHO to minimize the system overhead and the impact on end-users. Simulation results show that the proposed scheme is effective in relieving congestion and improving system performance across the overlapped heterogeneous radio networks as well as the users' satisfaction.
