Abstract:
Local IP Access (LIPA) allows an IP-capable user equipment (UE) connected via a femto cell direct access to other IP-capable devices in the local IP network. Selected IP Traffic Offload (SIPTO) is used to offload selected types of IP traffic towards a defined IP network close to the UE's point of attachment to the access network. LIPA PDN Connectivity indicates a PDP Context or a PDN Connection that gives access to services located in the local IP network of the femto cell subsystem. SIPTO PDN Connectivity indicates a PDP Context or PDN Connection that allows offload of selected types of IP traffic towards a defined IP network close to the UE's point of attachment to the access network. Systems, devices and methods are described herein that enable the identification of the type of connectivity available to a UE and enable session continuity for local cellular coverage.
