TR 23.829 (SA2)
Local IP Access and Selected IP Traffic Offload (LIPA-SIPTO)

|   ToC   |   3GPP‑Page   |   Help   |

(W-zip) V10.0.1    2011/10    43 p.


Rapporteur:  Mr. Hédé, Patrice

Support of Local IP access for the Home (e)NodeB Subsystem and of Selected IP traffic offload for the Home (e)NodeB Subsystem and for the macro layer network is required in TS 22.220 and TS 22.101.

This TR describes the following functionalities:
  • Local IP access – LIPA – to residential/corporate local network for Home (e)NodeB Subsystem;
  • Selected IP traffic offload – SIPTO – (e.g. Internet traffic) for Home (e)NodeB Subsystem;
  • Selected IP traffic offload (e.g. Internet traffic, corporate traffic) for the macro network (3G and LTE only).
The report is intended to analyse the architectural aspects to achieve these objectives and to gather the technical content until it can be included in the relevant technical specifications
