Patent number: 8983473Abstract: An LTE base station (100) conducts radio communication with a radio terminal which can execute a handover between a plurality of radio communication systems having different attainable communication rates. The LTE base station (100) is provided with a service detection unit (121A), which detects the classification of a communication service being used by a radio terminal, and a transmission unit (111), which sends the radio terminal a command for handover to the radio base station of a radio communication system, which handles the communication rate required for the communication service detected by the service detection unit (121A).Type: GrantFiled: July 26, 2010Date of Patent: March 17, 2015Assignee: KYOCERA CorporationInventors: Keiji Murakami, Hirokazu Matsunami, Kyoko Fujito

Patent number: 8983474Abstract: A radio controller 100 includes an acquisition unit configured to acquire a radio communication state of a neighboring cell around the cell formed by a base station 200, and a threshold determination unit configured to determine an in-out threshold based on an acquisition result of the radio communication state by the acquisition unit. The threshold determination unit calculates an estimated overall reception level within a frequency band at a point at which the reception level of the common control channel transmitted by the base station 200 becomes the highest in the cell formed by the base station 200, based on the reception level of the common control channel and the overall reception level, and determines the in-out threshold based on the calculated estimated overall reception level.Type: GrantFiled: June 3, 2011Date of Patent: March 17, 2015Assignee: NTT DOCOMO, INC.Inventors: Hiroyuki Hosono, Takeshi Terayama, Takeshi Okamoto

Patent number: 8983469Abstract: A method and system for managing neighbor cell information are disclosed in the present invention. A user equipment is reselected into a current Universal Terrestrial Radio Access (UTRA) cell from a former resident cell belonging to other system, and finds out that the former resident cell is not in a neighbor cell list of the current UTRA cell and the user equipment itself supports a neighbor cell relation maintenance function, and/or after receiving an indication notified by a network side that the user equipment can report neighbor cell relation, the user equipment reports an air interface signaling message carrying cell information of the former resident cell to a Radio Network Controller (RNC); the RNC receives and decodes the air interface signaling message, acquires the cell information of the former resident cell, and updates inter-system neighbor cell information according to the cell information of the former resident cell.Type: GrantFiled: May 18, 2011Date of Patent: March 17, 2015Assignee: ZTE CorporationInventors: Meifang He, Zhongming Chen, Yin Gao

Publication number: 20150072693Abstract: Cell relocation procedures to address handover between a macro radio network controller (RNC) and a home base station in a wireless communication network, while accounting for access control or membership verification procedures needed to support a Closed Subscriber Group (CSG) at the home base station. An example method begins with the receiving of a request for handover of the mobile terminal from an RNC of the macro wireless network. A closed subscriber group (CSG) identifier for the home base station and a cell access mode for the home base station are then sent, to a core network node associated with the macro wireless network, for use by the core network node in membership verification or access control for the mobile terminal. In response, the home base station receives a CSG membership status for the mobile terminal from the core network node.Type: ApplicationFiled: September 8, 2014Publication date: March 12, 2015Inventor: Angelo Centoza

Patent number: 8977272Abstract: A mobile communication system includes a first radio control device that manages a first cell, a second radio control device that manages a second cell, and a third radio control device. The second cell is set as a handover destination cell of the first cell. The third radio control device manages the second cell as a redundant configuration of the second radio control device. The third radio control device notifies the first radio control device of the third radio control device managing the second cell as the redundant configuration of the second radio control device. The first radio control device sets so that the third radio control device manages the second cell as the redundant configuration of the second radio control device.Type: GrantFiled: February 21, 2012Date of Patent: March 10, 2015Assignee: NTT DOCOMO, INC.Inventors: Hiroto Tooyama, Kouji Makino, Yoshifumi Morihiro, Narumi Umeda, Masato Hiraki, Shinsuke Sawamukai

Patent number: 8977265Abstract: A method for minimizing handoff latencies when a handoff is performed in a wireless network. An access point (AP) or base station associated to a current wireless station (STA) allows information required for a reassociation to the STA to be propagated to handoff-capable neighboring APs or base stations. When the STA moves, a neighboring AP or base station performs the reassociation to the STA on the basis of context. When a handoff procedure is performed, the time taken to receive context of a corresponding STA is reduced, such that a fast handoff can be implemented.Type: GrantFiled: December 3, 2004Date of Patent: March 10, 2015Assignees: Samsung Electronics Co., Ltd., University of Maryland College ParkInventors: In-Sun Lee, Kyuno-Hun Jang, Min-Ho Shin, William Albert Arbaugh, Arunesh Mishra

Publication number: 20150065145Abstract: An interference suppression method, base station and controlling node of the base station are disclosed. In the method, the controlling node informs via a first control signal the base station which is broadcasting a first synchronization signal containing a first cell identity (ID) and a first reference signal, of broadcasting a second synchronization signal containing a second cell ID and a second reference signal. The controlling node then informs via a second control signal the base station of adjusting signal powers of the first reference signal and the second reference signal to trigger a handover from the first cell ID to the second cell ID.Type: ApplicationFiled: April 17, 2012Publication date: March 5, 2015Applicant: TELEFONAKTIEBOLAGET L M ERICSSON (PUBL)Inventor: Haiyang Huang
