    • PROBLEM TO BE SOLVED: To provide a radio network system reducing the missing and redundancy of data in transmission and reception in a radio base station, and achieving a smooth handover when a handover execution is decided by a UE. SOLUTION: A UE1-0 monitors the down qualities of each node B, and determines the transmission of a handover request. A handover original node B2-0 receives the handover request from the UE1-0, and transmits the handover request and the information of the UE1-0 required for the handover to a handover destination node B2-1 through a c-plane pass between nodes B. The handover destination node B2-1 reserves a resource required for the handover on the basis of the handover request. The handover original node B2-0 and the handover destination node B2-1 mutually form a u-plane pass, and transfer user data. COPYRIGHT: (C)2008,JPO&INPIT

    • PROBLEM TO BE SOLVED: To suppress the occurrence of unneeded handover processing by preventing calls from concentrating on a specific Node-B even when a RNC (Radio Network Controller) is excluded from a mobile communication system.
      SOLUTION: A UE (User Equipment) 20 compares a reception SIR (Signal to Interference power Ratio) of an outgoing reference signal from a handover source node-B 30 connected currently to a radio channel with a reception SIR of an outgoing reference signal from a handover destination node-B 31 that is about to perform handover. When the reception SIR of the outgoing reference signal of the handover destination node-B 31 is larger than the reception SIR of the outgoing reference signal from the handover source node-B 30, the UE 20 monitors resource information 63 notified from the handover destination node-B 31, and performs a handover request to the handover destination node-B 31 when it is confirmed that the resource information 63 shows that handover is possible.

    • 要解决的问题:即使当从移动通信系统中排除RNC(无线网络控制器)时,也可以通过防止集中于特定节点B的呼叫来抑制不必要的切换处理的发生。 解决方案:UE(用户设备)20将来自当前连接到无线电信道的切换源节点-B 30的出站参考信号的接收SIR(信号与干扰功率比)与出站基准的接收SIR进行比较 来自即将进行切换的切换目的地节点-B 31的信号。 当切换目的地节点-B31的出站参考信号的接收SIR大于来自切换源节点-B 30的出站参考信号的接收SIR时,UE 20监视从切换目的地节点通知的资源信息63 -B31,并且当确认资源信息63示出可能进行切换时,对切换目的地节点-B 31执行切换请求。 版权所有(C)2007,JPO&INPIT

    • PROBLEM TO BE SOLVED: To effectively use a hardware source of a base station by eliminating an invalid cells from an active set with respect to an incoming high-speed signal such as E-DCH (enhanced-dedicated channels). SOLUTION: Base stations 100 and 101 measure a reception state of the incoming high-speed signal from a mobile terminal 1 and periodically notifies an RNC (radio network controller) 200 of the reception state. The RNC 200 determines cells to be eliminated from the active set on the basis of the reception state (for example, reception SIR) notified from the respective base stations 100 and 101. The RNC 200 transmits to the base station 100 and the mobile terminal 1 a radio channel release request to release a radio channel of an incoming high-speed signal set in cells determined to be eliminated from the active set. The base station 100 and the mobile terminal which receive the radio channel release request from the RNC 200 respectively release the radio channel to thereby eliminate the cell 110 from the active set.

    • PROBLEM TO BE SOLVED: To reduce interference with an adjacent cell when a mobile terminal moves between cells.
      SOLUTION: In a base station, when a propagation delay time threshold value discrimination section 12 discriminates that a propagation delay time measured by a propagation delay time measurement section 11 is greater than a preset propagation delay time threshold value and a Doppler frequency threshold value discrimination section 14 discriminates that a Doppler frequency measured by a Doppler frequency measurement section 13 is greater than a preset Doppler frequency threshold value, an additional scheduling control signal is selected, which is used by a scheduling control signal transmission section 16 to perform control of decreasing a transmission rate. Further, in other cases, a scheduling control signal for controlling a transmission rate and outputted from a scheduling control section 15 is selected, the selected additional scheduling control signal or the selected scheduling control signal is transmitted to the mobile terminal as a transmission rate control signal.

    • PROBLEM TO BE SOLVED: To provide a method for facilitating processing upon occurrence of collision of preambles and avoiding interference with other terminal.
      SOLUTION: When the number of signatures for specifying a terminal is increased and the signature is separated into a group and a personal in random access and there is no response of AICH (Access Indicator Channel) from a base station to preamble transmission, such a control as increasing the number of repeating transmission of preamble is performed in place of the power ramp control for raising transmission power of preamble. Both preambles of group and personal signatures are processed when the state of line is good, but the signature of group is processed at first and then the signature of personal is processed when the state of line is bad.
