摘要:
A communication duration configuring method is used in a mobile communication system with a relay station for relaying wireless communications between a base station and a mobile station. The method includes: configuring at least one of a downlink communication duration in which the relay station receives a transmission signal from the base station while limiting a transmission of a signal from the relay station to the mobile station, and an uplink communication duration in which the relay station transmits the transmission signal to the base station while limiting a transmission of a signal from the mobile station to the relay station; measuring a self-interference amount in the relay station; and controlling a configuration of the communication duration according to the self-interference amount.

In an intermittent communication system where an intermittent communication can be made between a base station and a mobile station, a transmitting unit of the mobile station transmits a request to start a normal communication after stopping an intermittent communication at timing different from the intermittent communication if a handover is determined to be required. A transiting unit transits from the intermittent communication to the normal communication after the transmitting unit transmits the request. A handover performing unit performs a handover upon completion of transition to the normal communication by the transiting unit.

A wireless communication system includes a relay station, first and second wireless base stations, a gateway device, and a mobile station. The gateway device is connected to the first and second wireless base stations by a cable. The first and second wireless base stations are interconnected by a cable. The relay station is connected wirelessly to the first wireless base station to perform relayed communication via the first wireless base station. When the mobile station at a lower level than the relay station executes handover to the second wireless base station, the first wireless base station switches a data transfer route by redirecting data which is not yet completely transmitted to the mobile station, to be forwarded to the second wireless base station.

A reordering method of sending packets, to which numbers indicating the packet order are added, to a mobile station from a base station, and rearranging the order of the packets at the mobile station, this includes forwarding from a source base station to a target base station, packets, not sent to the mobile station before a handover sequence, or packets, a confirmation response of proper reception has not been received from the mobile station, transmitting preferentially those packets from the target base station to the mobile base station and then transmitting packets received from a host station to the mobile station, giving packets information indicating that the packets are jump packets when transmitting the packets to the mobile station, received from the host station with the order jumped, deciding jump packets are not objects of reordering, and performing the reordering process for packets that are objects of reordering.
摘要:
A control method in a mobile communication system, that includes configuring a discard timer corresponding to a service data unit (SDU) for discarding the SDU according to a value of the timer; maintaining the value of the discard timer corresponding to the SDU when a handover is performed without restarting or resetting the value of the discard timer; and discarding the corresponding SDU when the maintained value of the discard timer reaches a given value.
摘要:
A mobile communication system, that includes a buffer storing packet data to be sent; and a controller configured for discarding the packet data according to a value of a timer corresponding to the packet data, maintaining the value of the timer corresponding to the packet data when a handover is performed without restarting or resetting the value of the timer, wherein the discarding further includes discarding the corresponding packet data when the value of the timer reaches a given value.

摘要:
A control method in a mobile communication system with a buffer unit for temporarily storing packet data to be sent, includes dropping the packet data stored in the buffer unit before sending when a drop timer corresponding to the packet data before sending reaches a given value or when a drop condition required by a drop mechanism accompanying the buffer unit is satisfied, and dropping the packet data stored in the buffer unit after sending when a drop timer corresponding to the packet data after sending reaches a given value.
摘要:
A communication system transmits a paging signal from a base station to a mobile terminal, via a designated carrier among multiple carriers. The communication system includes the base station that transmits the paging signal via the designated carrier, and further transmits via a carrier that is among the carriers and not the designated carrier, information that indicates the designated carrier; and the mobile terminal that based on the information received via a carrier to which the mobile terminal is connected, connects to the designated carrier and receives the paging signal transmitted via the designated carrier.
摘要:
A control method in a radio communication system wherein a radio communication device transmits, to another radio communication device, a predetermined signal that gives an opportunity to the other radio communication device to detect a change of a rule to be applied from a first rule to a second rule. The method includes transmitting, from the radio communication device, a paging signal at a timing specified by the first rule and a timing specified by the second rule and receiving, by the other radio communication device, the paging signal at the timing specified by the first rule when the predetermined signal was transmitted by the radio communication device to the other radio communication device but not received by the other radio communication device.
