Heterogeneous Signaling Framework for End-to-end QoS support in Next Generation Networks
Abstract
Next generation wireless communication systems aim to
handle diverse types of services across different types of
access technologies in a seamless way. This paper
proposes a next generation network architecture and
evaluates possible associated signaling strategies,
focusing in network-level QoS support aspects. The
scenarios handled cover terminal-initiated signaling,
network controlled signaling, and application-provider
controlled signaling. Possible message sequence charts
associated with these scenarios are presented and
discussed. The paper compares the relative merits of each
approach and concludes that the optimum QoS signaling
solution depends on the QoS models that will be used,
which are directly related to the business models chosen
by the operators.
