Abstract
Described aspects provide for improving the mobility of wireless communication devices between one network domain and another network domain, specifically, but not limited to, between a Wireless Local Area Network (WLAN) and a cellular network and the like. Present aspects provide for services to be moved seamlessly and in a reliable manner between the cellular and WLAN domains in order to minimize service disruption for the end user and provide the requisite Quality of Service (QoS) for the different applications. The aspects herein presented provide for various mechanisms that serve to improve the decision points related to when and what technology each service is expected to be associated with and provides better techniques to move the wireless communication device between cellular and WLAN domains when in-traffic and when idle.
