Publication number: 20230063007Abstract: A plasma lining structure is used in a process chamber to block direct line-of-sight for plasma generated within to grounded surface. The plasma lining structure includes a plurality of sections to cover at least one or more portions of an inside surface of a plasma confinement structure disposed in the process chamber. The sections of the plasma lining structure are positioned between a plasma region and the sidewall of the plasma confinement structure, when the plasma lining structure and the plasma confinement structure are disposed in the plasma chamber, such that the sections directly face the plasma region.Type: ApplicationFiled: February 2, 2021Publication date: March 2, 2023Inventors: John Holland, Stephan K.

Publication number: 20200344153Abstract: A packet processing method including a traffic classifier receives a first packet; the traffic classifier determines, in policy information in the traffic classifier and according to a first filtering rule that matches the first packet, a first service identifier that matches the first filtering rule, and an address, which matches the first filtering rule, of a first service routing trigger. The traffic classifier sends a second packet to the first service routing trigger. The policy information includes a filtering rule, an address of a service routing trigger, and a service identifier corresponding to the filtering rule. The filtering rule is used to identify a packet, and the service identifier is used to represent a sequence of a service node that processes the packet. The second packet is formed by adding the first service identifier to the first packet.Type: ApplicationFiled: July 13, 2020Publication date: October 29, 2020Applicant: Huawei Technologies Co., Ltd.Inventors: Dongjun Wu, Changjiang Yan, Shibi Huang

Patent number: 8594013Abstract: A system, method, and apparatus for implementing multimedia call continuity solve the problem that when a domain transfer happens, part of a media flow in a multimedia session cannot be transfer between bearers of different access modes. Besides a remote UE, the system further includes a multi-mode terminal MTF UE that supports media flow transfer between multiple modes and carries media flow transfer context information in an initiated media stream transfer request, and a media transfer function (MTF) that acts as an agent to initiate and perform a media renegotiation with the remote UE, according to the media flow transfer context information carried in the request. After the media renegotiation, the MTF UE or the MTF is adapted to release the media flow that needs to be transferred before the media renegotiation. Therefore, when a domain transfer happens, the media stream can be transferred between the bearers of different access modes that the MTF UE supports.Type: GrantFiled: May 22, 2009Date of Patent: November 26, 2013Assignee: Huawei Technologies Co., Ltd.Inventor: Dongjun Wu

Patent number: 7813509Abstract: A key distribution method for the next generation network (NGN), includes steps of: (a) a terminal sending a registration request message to a soft switch; (b) the soft switch sending an authentication request message to an authentication center; (c) the authentication center authenticating the terminal, then the soft switch distributing the session key to the terminal after the registration authentication being passed. The invention implements the key distribution during the registration authentication, thus the traffic is smaller, and it could be associated with the specialties of the NGN, and improve the efficiency of solving the security problem, the registration authentication of the terminal and the distribution of the key are more suitable specifically for the NGN.Type: GrantFiled: January 31, 2005Date of Patent: October 12, 2010Assignee: Huawei Technologies Co., Ltd.Inventors: Jun Yan, Dongjun Wu
