  • Patent number: 9439123
    Abstract: 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.

  • Publication number: 20120100856
    Abstract: 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.

  • Publication number: 20120057474
    Abstract: Due to the coverage size of the CSG cell, handover to macro-cell may occur frequently. These handovers are not desirable to both the user and operators. However, to disable or delay the handover of the CSG Cell would cause UE experiencing radio link failure and not able to re-establish connection to other cells. The present invention introduces a method for the UE to increase the stickiness to the CSG cells based on the user preferences and application requirements. When applied, it keeps the UE to the CSG cell as long as possible and reduces the possibility of connection re-establishment failure. The invention is also applicable to the corporate network deployment with multiple CSG cells.

  • Publication number: 20100309803
    Abstract: The invention provides a wireless communication terminal device and a gap allotting method capable of completing a measuring process at high speed and reducing the number of retransmissions. Upon determining that the average number of retransmissions exceeds the parameter for the average number of retransmissions in gap length change judging unit (115), a gap changing unit (125) changes the currently set gap length using a gap off duration “G_Off_Duration”. A gap pattern setting unit (120) sets a gap pattern based on a gap parameter or the changed gap length, and a measuring unit (130) creates a gap by using the set gap pattern and measures the reference signal in a physical layer input during the gap.

  • Publication number: 20100159950
    Abstract: It is possible to provide a radio communication base station device, a radio communication terminal device, and a radio communication method which reduce a signaling load and perform flexible gap allocation. A target gap length generation unit (120) uses gap parameter configuration information acquired from a gap parameter generation unit (110) to subtract a gap offset from a maximum permissible gap length so as to calculate a minimum gap length. Moreover, when a new gap offset is reported from a network, a target gap length generation unit (120) re-calculates the minimum gap length according to the maximum permissible gap length which can be used.

  • Publication number: 20100048209
    Abstract: A wireless communication terminal apparatus and a wireless communication method wherein a measurement operation, which is suitable for a long DRX/DTX interval, is controlled without providing any new signaling between a terminal and a base station. When a DRX threshold terminal status determining part (107) determines that a set a DRX/DTX interval is longer than a DRX threshold, a measurement process deciding part (108) instructs a measurement implementing part (109) to use information for cell reselection. The measurement implementing part (109) then uses the information for cell reselection to perform a measurement. When a result of the measurement satisfies a cell reselection requirement, a measurement report transmission process deciding part (110) decides a transmission of a measurement report, which is then transmitted from a transmitting part (111) to a wireless communication base station apparatus currently connected.
