Abstract: 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.
