Abstract  Abstract

Session continuity may be maintained when communication devices transition from communicating through network infrastructure (e.g. through a cellular network) to direct mode communications (e.g. a communication path directly between two communication devices). For example in switching from an infrastructure mode communication path to a direct mode communication path a method may include: determining a public-facing address corresponding to the infrastructure path; replacing for a packet that is to be transmitted over the direct mode communication path to a second communication device a source address field of the packet with the determined public-facing address; and encapsulating the packet with source and destination address fields corresponding to the first and second communication device through the direct mode communication path respectively.
