Inventor: ZHANG WENLIN
IPC: H04L12/28
Filed: 2004-12-01
Abstract: The invention relates to a method for establishment of the service tunnel inwireless local area network. The method includes: the service authentication authorization unit makes authentication and authorization to the user terminal of WLAN currently requesting service, and determines whether the authentication and authorization are passed, if so, produces service authorization information which comprises shared communication cryptic keys used between the user terminal of WLAN currently requesting service and the purpose packet data gateway, else finishes the current flow; the service authentication authorization unit sends the produced service authorization information which comprises shared communication cryptic keys to the purpose packet data gateway; the purpose packet data gateway negotiates with the user terminal currently requesting service to establish the relation of safe trust according to the achieved shared communication cryptic keys, if the establishment is successful, the purpose packet data gateway continues to assign tunnel resources and negotiate parameters to the user terminal currently requesting service, and completes the establishment of the' tunnel;  or else finishes the current flow. The method makes it possible to establish the safe service data tunnel between the user terminal and the packet data gateway.

Patent CA-2525147-A1 (CA)
Inventor: KITAMURA YASUFUMI
IPC: B21B1/02
Filed: 2004-05-20
Abstract: Fe-Cr alloy billet manufacturing method according to the present invention, since the blooming is carried out with the high reduction rate surface of the cast steel covered with a scale layer of a large area rate as 70 %  or more and without the descaling applied, can reduce the indentation and inclusion of the scale. Thereby, in the case of a billet for use in seamless steel pipes being manufactured from a steel strip of a Fe-Cr alloy, surface treatment before tube-making can be largely reduced. Thereby, when the Fe-Cr alloy billet is adopted in manufacturing seamless steel pipes, since even the Fe-Cr alloy steel pipe relatively hard to process can be manufactured at low manufacturing cost and efficiently, it can be widely applied in a field of manufacturing hot seamless steel pipes.
