Patent number: 9408110Abstract: A network includes a Mobile Station (MS) for sending a Service Flow (SF) modification request message to a Base Station (BS) to modify an SF. The BS sends a path modification request message to a serving SF Authorization (SFA) when there is the information on the SF. The BS also sends an SF modification response message comprising a Confirmation Code ‘Reject SF not found’ to the MS when there is no information on the SF. The serving SFA sends a resource reservation request message to an anchor SFA when there is the information on the SF, and sends a path modification response message comprising a Failure Indication (FI) ‘Requested Context Unavailable’ to the BS when there is no information on the SF. The anchor SFA sends a resource reservation response message comprising the FI ‘Requested Context Unavailable’ to the serving SFA when there is no information on the SF.Type: GrantFiled: December 15, 2009Date of Patent: August 2, 2016Assignee: Samsung Electronics Co., Ltd.Inventors: Yoon-Jeong Ha, Ki-Back Kim, Kwon-Young Kim, Hyung-Seok Ha, Jae-Jeong Shim, Jung-Shin Park, Han-Kyung Lee, Chang-Yeon Kim

Patent number: 9338531Abstract: A multiplexer capable of automatically and dynamically selecting a correct or the best input out of a pre-configurable set of alternative inputs, based on the current status of the alternative inputs. An input status-sensitive, dynamic, M-by-M digital cross-connect can be formed out of an arrangement of M (an integer) instances of such input-controllable dynamic M:1 multiplexers. An application is an SDH/SONET cross-connect system that is able to perform a protection-switch for any number, up to all, of its output paths, simultaneously, if necessary, thereby enabling a short and deterministic latency for individual-path-granular protection-switch process for cross-connects of unlimited capacity. Another application is an SDH/SONET path that can be dynamically shared, even at a single time-slot granularity, among multiple path sources.Type: GrantFiled: April 18, 2015Date of Patent: May 10, 2016Inventor: Mark Henrik Sandstrom
