Future wireless mobile devices will have to support a variety of heterogeneous access technologies while having a limited number of transceiver chains. One of the most challenging tasks remains how to support wireless access in one of the technologies, while preparing a "Smooth transition" to another, especially to technologies with a lengthy network entry such as WiMAX. This paper proposes an efficient way to organize a WiMAX network entry process while continuing a communication session with stringent QoS requirements via WLAN. The authors advocate the prioritization of the strict WiMAX timing over the contention-based WLAN channel access.
