Abstract:
LIPA PDN Connectivity indicates a PDP Context (in the case of a GERAN or UTRAN femto cell connected to a GPRS core network) or a PDN Connection (in the case of an E-UTRAN femto cell connected to a GPRS core network) 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 (e.g. internet traffic) towards a defined IP network close to the UE's point of attachment to the access network. Remote PDN Connectivity indicates a regular PDP Context or PDN Connection established neither according to LIPA PDN Connectivity nor SIPTO PDN Connectivity. 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.
