Embodiment Construction

[0054]FIG. 1 is a schematic diagram of a data exchange process through a terminal device 131 between a plurality of access networks 111, 113, 115 and 117 communicatively connected to the terminal device 131 according to the present invention. The EPD (End Device) 131 may be, for example but not limited to, a notebook, a personal computer, a telephone, a server, a PDA (Personal Digital Assistant), and a video game console. Each of the plurality of access networks 111, 113, 115 and 117 is a circuit switched data network or a packet switched data network. Multiple access networks 111, 113, 115 and 117 can work according to the same protocol. In another embodiment of the present invention, each of the plurality of access networks 111, 113, 115 and 117 operates according to a different protocol, and these protocols are not compatible with each other in communication. Multiple access networks 111, 113, 115 and 117 may be managed by one or more service providers. Typical examples o...

Abstract

An end-point device that is attached to a primary access point delivers a detachment logic and network address of at least a secondary access point to the primary access point. The end-point device informs the primary access point about intended detachment. The detachment logic directs the primary access point to forward data destined for the end-point device to the secondary access point after detachment in anticipation that the end-point device will be attached to the secondary access point even if detached from the primary access point. The end-point device delivers the detachment logic anytime after attachment or after detachment from the primary access point. The detachment logic directs the primary access point to store session information and network association information so that the end-point device is relieved from re-establishing communication session and re-establishing association with a data network while switching attachment from the primary access point to another access point. The primary access point has an alternate pathway to communicate with the end-point device even after detachment.

Description

technical field [0001] The present invention relates to data communication and more particularly to the transfer of packet data by terminal equipment from a node belonging to one data network to another node belonging to another data network of a different kind. Background technique [0002] Computers, video game consoles, notebook computers, telephones, PDAs (Personal Digital Assistants), and other types of terminals can be used in packet-switched data networks. The packet-switched data network described here may be, for example, an EDGE (Enhanced Data Rates for GSM Evolution) network, a GSM (Global System for Mobile Communications) network, a CDMA (Code Division Multiple Access) network, an IEEE (Institute of Electrical and Electronics Engineers) 802.11 Network, Bluetooth, WiMax (Worldwide Interoperability for Microwave Access) network, Internet, intranet, satellite network, etc. The terminals exchange data packets with the packet-switched network, the data packets typica...
