In this article, based on the overview of network coupling structure between radio access technologies, the concept of joint radio resource management built onto the reference structure is introduced. In order to optimize usage of radio resource and jointly designed from the user perspective, a joint scheduling mechanism allowing traffic to be split over a tightly coupled radio network supported by an adaptive radio multihoming approach is deliberately discussed. With respect to the time-division access scheme in HIPERLAN/2, which is selected as one example of WLAN, algorithms and performance of traffic scheduling in such a radio access technology are given. The required synchronization scheme supporting traffic splitting is also introduced.read more

UMTS to WLAN Handover based on A Priori Knowledge of the Networks
TL;DR: Simulation results in a WLAN hot spot deployment show that handover based on a priori knowledge of the networks increases handover success rate, compared to classical blind handover, and can be integrated into several B3G handover algorithms, to decrease handover delay and complexity.
