Abstract

Aspects of the present invention relate to methods and entities involved in enabling and improving inter-domain handover. A PS based RAN such as eUTRAN can identify which potential handover to prepare and which handover to initiate, PS-PS or SR-VCC based on: (1) the UE's SR-VCC capabilities, (2) “SR-VCC indication” from the MME, (3) active VoIP bearer, and (4) target cell capabilities.
