Patent number: 8185114Abstract: Disclosed are a system and a method for optimizing a handover process in a mobile broadband wireless access system. The method performs handover in a mobile communication system including a mobile subscriber station, a serving base station currently providing service to the mobile subscriber station, and at least one neighbor base stations adjacent to the serving base station. The method includes the steps of receiving a handover request from the mobile subscriber station by the serving base station; instructing the mobile subscriber station to perform handover by the serving base station in response to the handover request from the mobile subscriber station and performing by the mobile subscriber station a network reentry process for fast handover in accordance with information included in a handover instruction from the serving base station.Type: GrantFiled: March 16, 2010Date of Patent: May 22, 2012Assignee: Samsung Electronics Co., LtdInventors: Jung-Won Kim, Bo-Kyung Wang, Yong Chang

Patent number: 7813320Abstract: A handover method and system in a communication system. In the method, a serving Base Station (BS) broadcasts neighbor BS information including BS identifiers and preamble indices of a plurality of neighbor BSs, receives a handover request message from a Mobile Station (MS), the handover request message including a first set of at least one BS identifier and at least one preamble index for at least one neighbor BS among the plurality of neighbor BSs, and transmits a handover response message to the MS, the handover response message including a second set of at least one BS identifier and at least one preamble index for at least one recommended neighbor BS.Type: GrantFiled: June 29, 2009Date of Patent: October 12, 2010Assignee: Samsung Electronics Co., LtdInventors: Jung-Won Kim, Tae-Won Kim, Bo-Kyung Wang, Yong Chang, Hong-Sung Chang

Patent number: 7773524Abstract: An apparatus and method for using an Automatic Repeat reQuest (ARQ) in a Broadband Wireless Access (BWA) communication system are provided. In a transmitting method of a wireless communication system, a Media Access Control (MAC) layer creates a packet and transmits it to a physical layer, the physical layer generates a Hybrid ARQ (HARQ) burst using the packet received from the MAC layer and transmits it, the physical layer generates a HARQ ending signal and transmits it to the MAC layer when HARQ transmission of the packet is discontinued, and the MAC layer drives an ARQ retransmission timer for the packet in response to the HARQ ending signal.Type: GrantFiled: February 20, 2007Date of Patent: August 10, 2010Assignee: Samsung Electronics Co., LtdInventors: Geun-Hwi Lim, Joon-Ho Park, Bo-Kyung Wang, Yong Chang

Patent number: 7574210Abstract: Disclosed is a handover system in a BWA communication system. In the system, a serving BS broadcasts neighbor BS information including BS identifiers of a plurality of neighbor BSs and reference signal indices indicating reference signals used by the neighbor BSs, a MS receives the neighbor BS information and requests a scanning interval to the serving BS at a timing point at which the MS wants to perform a scanning, the serving BS allocates the scanning interval to the MS in response to a request for the scanning interval, and the MS scans reference signals received from the neighbor BSs during the scanning interval in response to the neighbor BS information.Type: GrantFiled: June 7, 2005Date of Patent: August 11, 2009Assignee: Samsung Electronics Co., LtdInventors: Jung-Won Kim, Tae-Won Kim, Bo-Kyung Wang, Yong Chang, Hong-Sung Chang
