Patent number: 11405831Abstract: When a handover request for performing a handover of a terminal (70) from a macro cell C1 to a CSG cell C2 is received from an SeNB 10 (S8), a base station (TeNB) (40) of the CSG cell C2 transmits a handover response in accordance with a handover enabled/disabled state (S12). The handover response includes an identifier of the terminal (70) in the CSG cell C2. Upon receiving the response, the SeNB (10) notifies the identifier to the terminal (70) (S14). The TeNB (40) repeatedly transmits a dedicated signal containing a handover command via a dedicated channel set using the identifier at an interval shorter than a gap period (S18). Accordingly, whether or not access is permitted can be judged promptly and a smooth handover can be realized.Type: GrantFiled: March 18, 2021Date of Patent: August 2, 2022Assignee: Panasonic Intellectual Property Corporation of AmericaInventors: Hidenori Matsuo, Takahisa Aoyama, Hong Tat Toh, Hidetoshi Suzuki

Patent number: 8817681Abstract: A wireless communication terminal apparatus and wireless communication method, wherein the time necessary for implementation of handover is reduced without increasing the complexity of the configuration of the wireless communication terminal apparatus. A gap confirmation unit (105) determines to start the UE-initiated GP at the current DRX cycle in cases when the extended DRX active period is shorter than the UE-initiated GP start offset, and determines to start the UE-initiated GP at the next DRX cycle in cases when the extended DRX active period is longer than the UE-initiated GP start offset. A UE-initiated GP configuration unit (106) generates a gap pattern at the determined DRX cycle.Type: GrantFiled: April 19, 2010Date of Patent: August 26, 2014Assignee: Panasonic Intellectual Property Corporation of AmericaInventors: Takahisa Aoyama, Hong Tat Toh, Hong Cheng, Benjamin Tien Ming Koh, Pek Yew Tan

Publication number: 20120100856Abstract: In a mobile communication system, a handover of a terminal device (MT) from a macrocell base station (eNB) to a small cell base station (HeNB) is controlled via a host device (MME or HeNB-GW). Physical cell ID deployment map information (PCI deployment map information), which includes at least information (PCI/CGI map information) indicating the correspondences between physical cell IDs and unique cell IDs of CSG cells for which access is granted, is generated in the host device (MME or HeNB-GW). When the terminal device measures the reception quality for surrounding CSG cells for handover control to any of the CSG cells, the terminal device uses the PCI deployment map information to generate a measurement result report. Thus, a service interruption caused by handover control to an inaccessible small cell can be avoided, and the wait time for handover control can be reduced.Type: ApplicationFiled: January 6, 2012Publication date: April 26, 2012Applicant: PANASONIC CORPORATIONInventors: Chie Ishida, Takahisa Aoyama, Hong Tat Toh, Hong Cheng, Tien Ming Benjamin Koh
