Abstract: To achieve load distribution in a short period of time, a mobile communication system includes a mobile terminal (505), a radio base station (503), and a relay base station (504) that relays radio communication between the radio base station (503) and the mobile terminal (505). In the mobile communication system having such a configuration, the radio base station (503) includes control means for handing over the subordinate relay base station (504) to a neighboring radio base station (503) when a load on the radio base station is greater than a predetermined threshold. The control means is preferably configured to confirm whether the neighboring base station (503) can accept the relay base station (504) upon handover of the relay base station (504).

Abstract: In order to reduce the occurrence of call loss in mobile stations while suppressing degradation of communication quality in a handover destination cell, a communication unit (11) forming an eNB (10) receives, from another eNB located adjacent to an own eNB, a first reception quality in a cell formed by the own eNB and a second reception quality in a cell formed by the another eNB. The first reception quality and the second reception quality are measured by one or more UE that are in radio communication with the another eNB. A control unit (12) accepts a call associated with UE which satisfies a first condition that the first reception quality is higher than the second reception quality in preference to a call associated with UE which does not satisfy the first condition.

Abstract: A wireless base station that solves a problem in which both the suppression of a power consumption of a wireless base station and the reduction of the period that a mobile terminal takes to identify a cell cannot be satisfied at a time is provided. Determination section 101 determines whether or not a mobile terminal is present in a cell that wireless base station 10a manages. If determination section 101 determines that a mobile terminal is present, control section 102 sets wireless base station 10a for a first transmission repetition as a transmission repetition of a pilot signal; if determination section 101 determines that no mobile terminal is present, control section 102 sets wireless base station 10a for a second transmission repetition lower than the first transmission repetition as a transmission repetition of the pilot signal.

Abstract: In a mobile communication system, an interference equalization method is installed in a radio base station for managing a cell configured of sectors, thus equalizing interference between sectors in uplink communication and improving sector-user throughputs. In the situation that congestion occurs in a second sector adjacent to a first sector, a handover from the second sector to the first sector is accelerated when uplink interference of the first sector is equal to or above a first threshold while the usage rate of resource blocks in the first sector is equal to or below a second threshold. This accelerates a handover from the second sector undergoing congestion to the first sector having available resource blocks, thus equalizing uplink interference between these sectors.

Abstract: In order to reduce the occurrence of call loss in mobile stations while suppressing degradation of communication quality in a handover destination cell, a communication unit (11) forming an eNB (10) receives, from another eNB located adjacent to an own eNB, a first reception quality in a cell formed by the own eNB and a second reception quality in a cell formed by the another eNB.

A control unit (12) accepts a call associated with UE which satisfies a first condition that the first reception quality is higher than the second reception quality in preference to a call associated with UE which does not satisfy the first condition.

Abstract: An integrative radio base station holds station data required for operation including information on the cell managed by itself and the information on the cells managed by an adjacent integrative radio base stations. If information on the cells of the destination of a mobile terminal is not held at the time of the handover of the mobile terminal, the information is acquired from a station data management device. The station data management device manages station data for each integrative radio base station and transmits information on the cell requested from the integrative radio base station to a source that made the request.

Abstract: Disclosed is the retransmission control method used in a mobile communication system including mobile terminals (MTs), base stations (BSs) and the radio network controller (RNC) which controls the BSs. When an MT detects data error, it sends the 1st negative acknowledgement (NACK) to the BS. This first NACK includes a cell ID which indicates the cell where the reception data is transmitted. When cell ID in this 1st NACK includes cell ID of a cell besides the cell which the BS itself manages, the BS sends the 2nd NACK to the RNC. This 2nd NACK includes the cell ID and the data number to specify the data in which the mobile terminal detected the data error. The RNC decides the BS where data is to be retransmitted based on the cell IDs in the 2nd NACK and sends data retransmission request to the decided BS.

Abstract: A first network apparatus transmits data via a plurality of sequenced packets. A second network apparatus sets a packet holding time to be an appropriate value for every service class, and holds an earlier arriving packet up to the maximum packet holding time when an earlier transmitted packet from the first network apparatus is overtaken and a later transmitted packet arrives earlier. In addition, the second network apparatus rearranges the packets in the transmitted sequence if the overtaken packet arrives during the packet holding time, and gives up rearranging the packets in the transmitted sequence if the overtaken packet does not arrive during the packet holding time.
