Claim 0:
1. A method for operating a replication control component, the method comprising:
collecting information about mobility of a user equipment;
determining, based on the information, that a handover takes place by which a data session exchanged via a cellular network between a serving application instance and the user equipment is transferred from the serving application instance to a target application instance selected from a plurality of application instances located in a cloud environment, wherein the data session comprises session state data;
determining a location of the target application instance in the cloud environment;
determining target replica locations of replica of the session state data individually on a per session basis for said data session during its runtime taking into account the location of the target application instance, wherein the replica comprises a master replica and at least one slave replica and the target replica locations are determined for the master replica and the at least one slave replica;
predicting a trajectory of the user equipment;
determining the target replica location of the master replica that is collocated at a first node as close as possible to the serving application instance taking into account the projected trajectory;
determining the target replica location of the at least one slave replica that is located in at least one second node which is a direct neighbor of the first node; and
transmitting, to a data handling component, the target replica location information and an instruction to the data handling component to distribute the replica to the target replica locations.
