摘要： There is provided a mobile communication system capable of improving the throughput. In this system, a radio base station device (1022) waits for an upstream retransmission packet for a predetermined period of time before the moment when the retransmission time out expiration time has come and transmits a retransmission wait release request to a radio network control device (1031). When the radio base station device (1022) receives a retransmission wait release response instructing to stop the retransmission wait from the radio network control device (1031), it stops wait for the upstream packet retransmission. When the radio network control device (1031) has confirmed that the upstream packet has been received from another radio base station device upon reception of the retransmission wait release request, it creates the retransmission wait release response instruction stop of the retransmission wait and transmits it to the radio base station device (1022).

摘要： RLC processing section 106 supplies packet data requested for retransmission from a mobile terminal and new packet data not requested for retransmission to buffer 107 corresponding to data amounts controlled in HS-DSCH/FP processing section 108. Buffer 107 temporarily stores the packet data requested for retransmission and the new packet data not requested for retransmission to output at predetermined timing. HS-DSCH/FP processing section 108 detects a receivable data amount of the mobile terminal using CQI, and controls RLC processing section 106 so that the amount of data stored of packet data in buffer 107 does not exceed the receivable data amount of the mobile terminal. It is thereby possible to decrease the number of retransmissions to improve the throughput, and prevent suspension of the communication and disconnection of the channel.

摘要： There is provided a control station device capable of suppressing a traffic amount by discarding packet data to be discarded by a control station device, without transmitting the packet data from the base station device to the control station device. In this device, a buffer (102) stores upstream packet data and discards it without outputting it when a predetermined time has elapsed after the storing of the upstream packet data. According to maximum wait time information, a timer management unit (106) makes an instruction to discard the upstream packet data which is to be discarded even if transmitted to an RNC, without transmitting it to the RNC (122). An alignment buffer (112) corrects the upstream packet data order inversion and discards the upstream packet data for which the maximum wait time has elapsed. A timer management unit (113) sets the maximum wait time and instructs the alignment buffer (112) to discard the upstream packet data for which the maximum wait time has elapsed.

摘要： A packet communication apparatus and a packet communication method capable of suppressing decrease in overall system throughput and preventing communication from being reset or disconnected. An ACK generation section (130) generates an ACK/NACK to indicate whether or not data transmitted on the radio channel has been demodulated correctly. A channel quality measurement section (140) measures channel quality of the radio channel from an AMD-PDU received. According to the ACK/NACK generation situation and the channel quality measured, a WSN determination section (160) determines a WSN appropriate for the channel condition and outputs the WSN to a status PDU generation section (170). More specifically, the WSN determination section (160) determines the WSN, for example, according to the ratio of ACK/NACKs generated in the near past and SIR measurement values. When the status PDU generation section (170) generates a status PDU, it sets the WSN determined by the WSN determination section (160) in the WSN field.

摘要： A mobile wireless system includes a first gateway (L-PGW), a second gateway (PGW), a first access point (HeNB) capable of establishing a communication path simultaneously with the first and second gateways, and a second access point (eNB) capable of establishing a communication path only with the PGW. When a mobile terminal connected to the HeNB and communicating with a communication destination node using a first path through the L-PGW switches a connection destination to the eNB, the HeNB establishes a second path through the HeNB and the PGW, while maintaining the first path. The HeNB transmits data, which has been transmitted to the HeNB along the first path, to the eNB along the second path, until the UE is connected to the eNB, and a third path to the communication destination node through the PGW is established. Accordingly, an interruption time of data reception involved in handover is shortened.

摘要： The invention relates to a method for distributing control signaling for session control of a multicast or broadcast service within a mobile communication network. Furthermore the invention also provides a base station, mobile terminal and communication system to perform the proposed method. In order to reduce the number of signaling connections for the service, the invention proposes to avoid the initial distribution of session control signaling in the entire mobile communications network or service area. Rather than providing service related control signaling connections upon session start, the control signaling connections are set up in response to service requests of the mobile terminals requesting the service. According to one further aspect, the mobile terminals send the service requests based on service announcements available at the mobile terminals, i.e. in contrast to conventional implementations, the mobile terminals do not await a notification of the access network on the availability of the service within the cell.

摘要： Disclosed are a radio communication base station device and a radio communication method which can reduce the interruption time of a service being received by UE while suppressing a resource consumption amount in an SFN area when the UE performs a handover from the SFN area to a non-SNF area. An MBMS reception request identification unit (127) judges an RRC message inputted from the UE (100). If an MBMS reception request is contained, an MBMS reception request is transmitted to an MBMS reception request storage unit (124). Moreover, when the RRC message from the UE (100) contains an adjacent cell reception quality measurement result, a handover decision unit (126) judges whether to perform a handover to the adjacent cell. The MBMS reception request storage unit (124) stores the MBMS reception request outputted from the MBMS reception request identification unit (127). When the handover decision unit (126) which has decided the handover requests for transmission of an MBMS reception request, the MBMS reception request storage unit (124) transmits the MBMS reception request to an MME (140).
