unavailable at this time the data and video sessions are transferred to the cellular access network 2 1230 in a third scenario the above two scenarios can be combined to see how the communication transfers from ethernet ip network to wireless lan network to cellular network with or without the user knowledge and intervention based on policies and user preferences to continue the communication without disruption in the communication referring now to fig2 there is illustrated a block diagram of an exemplary interconnection architecture for communication by a terminal such as terminal 1 1210 over heterogeneous networks with multiple peers such as the network shown in fig1 an application layer 1010 generates or interprets information provides mechanisms for generation and consumption of information and may also provide encryption decryption compression and other processing support communication over multiple heterogeneous networks require matching the resource s availability application requirements for the resources and the coordination management and adaptation to meet these demands a session convergence layer 1020 implements this functionality in the preferred embodiment of the invention the session convergence layer 1020 accepts the information processed by a presentation layer 1035 and then directs the information to the application in such a way so as to not change the existing communication method by the application to the communication mediums another function of the session convergence layer 1020 is resource management to avoid conflict of resources by competing presentation layers usage the implementation of the resource management is dependent on the implementation on the target application.
