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

Interworking of WLAN and 3G systems
TL;DR: In contrast to several approaches that investigate solutions for the IP layer, the focus of the paper is on mechanisms on the link layer to improve the handover, respectively scanning other air-interfaces, measurements and appropriate triggers from the link Layer that are considered in the hand over decision process.
