Patent ID: 7894458

Claim:
An IP Telecom Network system, comprising: at least one dual-address connectionless data network with a plurality of devices; a plurality of IP networks; and a plurality of edge gateway devices; wherein the plurality of IP networks connects to the at least one dual-address connectionless data network through the plurality of edge gateway devices; wherein the at least one dual-address connectionless data network includes at least one address mapping device with an address mapping table; wherein each device within the dual-address connectionless data network and each edge gateway device are individually assigned an address of the dual-address connectionless data network, and each device within the IP network and each edge gateway device are individually assigned an IP address; wherein a mapping relationship between the IP address and the dual-address data networks address is stored in the address mapping table of the address mapping device; wherein both addresses in the dual-address connectionless data network is the IP address used to address outside the dual-address connectionless data network; wherein the dual-address connectionless data network address is used to address within the dual-address connectionless data network; wherein the two operation modes which can be used within the dual-address connectionless data network at the same time are the connectionless operation mode and a connection-oriented tunnel operation mode; and wherein an assignment for address of the dual-address connectionless data network follows a location related layered structure address assignment rule.
