Abstract
Recently,
the integration of wireless radio networks with backhaul and core
networks has gained significant attention due to advances in air
interfaces, emergence of new delay-sensitive applications and ever
increasing proliferation of IP technologies towards the base
stations. Within standardization and research communities,
efforts are underway to address the issues of end-to-end signaling
delay in architectures integrating the radio access network based on
CDMA2000 Evolution Data Only Rev. A (EV-DOrA) with the IP Multimedia
Subsystem (IMS). Keeping signaling delay low, however, is a challenge
due to the text-based nature of the Session Initiation Protocol (SIP),
and, more significantly, due to the lossy and capacity constrained
properties of wireless links. This presentation will discuss
challenges in developing a model to analyze the IMS session setup delay
end-to-end and cross-layer. The cross-layer EV-DO radio link model
presented is analytical, but practical, we believe, and verified by
simulations and measurements. We ask: can IMS be designed
with a session setup performance that is reasonably independent of the
radio link quality?
