METHOD FOR TRANSFERRING A FLOW BETWEEN HETEROGENEOUS ACCESS POINTS

A method is provided for handing off flows. The flow, having a flow identifier, is established between a terminal and a correspondent. The terminal has as many terminal identifiers as access interfaces to access networks of mutually different data technologies. A first execution entity converts a ha...

Summary:A method is provided for handing off flows. The flow, having a flow identifier, is established between a terminal and a correspondent. The terminal has as many terminal identifiers as access interfaces to access networks of mutually different data technologies. A first execution entity converts a handoff execution order emanating from a decision entity into execution messages by taking into account a hierarchy of execution entities of a current network. After a handoff decision has been taken for a given pair of flow and terminal identifiers, the decision entity sends an execution order to the first execution entity. The first execution entity: selects a mobility protocol from the mobility protocols supported by the execution entities of the hierarchy associated with the current network; selects in the hierarchy at least one execution entity responsible for executing the mobility protocol; and sends to the selected execution entities respective execution messages.
