A mobile core network with distributed data services is provided. The mobile core network includes distributed mobile cores associated with mobile data service (MDS) agents at distributed data centers. A central MDS agent is host at a central data center providing legacy mobility management entity (MME) functions. The central MDS agent and the MDS agents at the distributed data centers coordinate with each other for synchronizing context information, such as subscriber data, session context data and metrics data of UEs, so that the context information is available at the central data center and the distributed data centers when or before it is requested.

System and method for mobile core data services

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.
