Method for transferring a flow between two heterogeneous access points

The invention relates to a method for transferring a flow between a first access point of a first access network, or current network, to an IP core network to which a terminal is connected, and a second access point of a second access network, or visited network, to the core network. The flow with an F_ID identifier is established between the terminal and a party. The terminal has as many identifiers as access interfaces to access networks of different given technologies. The method is implemented by a pair of entities including a transfer decision entity (HOD*) and a first execution entity (HOE*). The first execution entity (HOE*) converts a transfer execution order from the decision entity into execution messages while taking into account a hierarchy of execution entities of the current network, that comprises at least one other execution entity (HOE). Once a transfer decision is made for a given pair of flow and terminal identifiers, the decision entity (HOD*) sends an execution order (HO_Decision) to the
