Abstract
Session Inter-Device (SID) mobility networks (50, 100, 150) are described in which a seamless transfer of a communication session from a first device (56, 106, 116) to a second device (66, 116, 166) can be achieved without interrupting the active session. According to the SID mobility network (50), the transfer can be accomplished by transferring away from the Transferring Node or first device (56) the IP address associated with the active session (58) so that the network (50) will route the session to the desired Target Node or second device (66). The Transferring Node (56) transfers its IP address (58) to the Agent (60) and stops requesting data packets addressed to its IP address (58). The Agent (60) then begins to request and eventually receive the packets addressed to the Transferring Node's IP address (58). The Agent (60) then transfers the packets to the Target Node (66). In an alternate SID mobility network (100), the Transferring Node (106) transfers a session specific IP address (114) to the Agent (110). The Agent (110) then transfers packets sent to the session specific IP address (114) to the Target Node (120). In another SID mobility network (150), the Transferring Nod…
