Abstract: This deliverable starts by presenting a reference network architecture for inter-working between, Ethernet based, SPC access network and a fixed wireless access network. It then describes two use cases, used to identify different user “mobility types”, and solutions for supporting session continuity. A session at the application layer invariably puts a number of requirements to the underlying layers. Therefore the requirements on the application, transport, network and link layers are analyzed and some results from experimental tests on the impact of different link layer interfaces and applications running on different Operation Systems (OS) are presented. The policy framework specified in previous deliverables is revised and policy control workflow has been illustrated based on different mobility mechanisms. The Authentication and Authorization (AA) scheme that is being used in the SPC platform to support nomadism is also revisited and some innovative methods for minimizing the overall Handover (HO) delay, by binding the AA procedure with the layer 2 connections provisioning, are presented. The document also presents a summary of the specification and deployment of a MIP based implementation to support session continuity.
