This Technical Report describes the solutions to implement the architectural aspects based on the requirements from TS 22.220
, clauses 5.7 and 5.9, and TS 22.101
, clause 4.3.5
, for LIPA and SIPTO at the local network.
the support of mobility for LIPA between the H(e)NBs located in the local IP network;
functionality to support Selected IP Traffic Offload requirements at the local network, including mobility.
The report is intended to document the analysis of the architectural aspects to achieve these objectives in order to include the solutions in the relevant technical specifications.
