The 3GPP IP Multimedia Subsystem (IMS) is currently expected to provide the basic architecture framework for the Next Generation Network which will bridge the traditional divide between circuit-switched and packet-switched networks and consolidate both sides into one single network for all services. Therefore, the imminent commercial roll-out of IMS will(More)

One aspect highly neglected so far in Next Generation Networks development is that their access-agnostic service architecture requires NGN services to provide adequate user perception for a broad range of underlying access network technologies. Automated service testing for a wide variety of access technologies will therefore become indispensable in the(More)
