Abstract: A base transceiver station of a soft handover destination node does not perform control by using Hybrid Automatic Repeat Request, and a base transceiver station of a soft handover origin node sends data to a mobile node according to control performed by using Hybrid Automatic Repeat Request when the soft handover occurs. A radio network controller sends data destined for the mobile node only to the base transceiver station of the soft handover origin node. When the data is transferred from the base transceiver station of the soft handover origin node, the radio network controller transfers the data to the base transceiver station of the soft handover destination node. When a request to resend the data is received from the base transceiver station of the soft handover destination node, the radio network controller transfers the resend request to the base transceiver station of the soft handover origin node.

Abstract: To obtain a mobile communication system that can perform handover without causing instantaneous interruption and packet loss and without lowering the performance of the entire network when a mobile communication system is realized by the IP network. During handover of a MN from a handover source cell to a handover destination cell, the MN obtains a CoA of a link, to which a handover destination BTS is connected, and sends it to a handover source BTS. When the handover source BTS receives the CoA from the MN, it measures a data transfer time to the handover destination BTS and transfers an IP packet destined to the MN to the handover destination BTS, and after the transfer time has passed, the handover source BTS sends it to the MN as radio data. The handover destination BTS sends the transferred data to the MN as radio data. The MN sends a message including the CoA to a CN when the handover completed. When the CN receives the message, it routes and directly sends data to the handover destination BTS.

Abstract: When a mobile node makes handover, the mobile node issues a binding update message and sends the binding update message to a base transceiver station from which handover is made. When the base transceiver station from which handover is made sends radio data to the mobile node, it also transfers the same data to a base transceiver station to which handover is made, so that the base transceiver station to which handover is made also sends the radio data to the mobile node. As a result, the mobile node receives the radio data via an IP network from both the base transceiver station from which handover is made and the base transceiver station to which handover is made. Since the mobile node makes soft handover, the handover can be made without causing a communication short-break and a packet loss.

Abstract: User-authentication data, terminal information, and encoded information are received through infrared communication and/or communication using an IC card, a position-registration request is made to a micro radio-base station 2 on the basis of the received information, and communication performed between a mobile terminal 3 and a micro radio-base-station device is controlled.

Abstract: There is provided a reset circuit in which the necessity for adjusting the constant of the pull-up resistor of the reset trigger signal is eliminated to assure a reliable reset operation. The reset circuit has another function to cancel the reset, even when clocks are stopped on power up. During the normal operation, a clock stop detection signal CALMB takes on the level ‘H’ so that a reset trigger signal CPURSTB is masked by an OR gate circuit 8. If the clocks are stopped during the normal operation, and the clock stop detection signal CALMB is ‘L’, the reset trigger signal CPURSTB is passed through OR gate circuits 6, 8 and AND gate circuit 10, and output as a reset output signal RSTB.

Abstract: A clock producing circuit comprises a phase comparator to produce a comparison signal representing phase difference between a first output clock produced by a first PLL and a second output clock produced by a second PLL. The comparison signal is supplied to a digital filter included in the second PLL. The digital filter updates filter coefficients thereof to reduce the phase difference while the first output clock is selected as a selected output signal. Thus, the second output clock coincides the first output clock in phase. If the first reference clock disappears, the second output clock instead of the first output clock is selected as the selected output clock. At the same time, the digital filter stops updating the filter coefficients. A phase shift is not caused in the selected output clock by changing from the first output clock to the second output clock.
