20090207855 | COMMUNICATIONS SYSTEM, COMMUNICATIONS PROCESSING METHOD, AND NODES - To the logical links established between the first node and the second node by use of the first protocol belonging to the first layer, a signal, which is a signal of the second protocol belonging to the second layer higher than the first layer and to which signal the information identifying the transmission source node is transmitted. The first and the second nodes manage the communications links in association with the node identifier added to the signal received through the communications links. | 08-20-2009 |
20090252108 | BASE STATION, WIRELESS CONTROL APPARATUS, AND WIRELESS APPARATUS - In a base station that performs internal data transfer based on the CPRI, a dividing part divides the data to be transferred into division data. A transfer part transfers the division data by using a plurality of CPRI links. A receiving part receives the division data transferred by the CPRI links. A restoring part restores the original data from the division data received by the receiving part. | 10-08-2009 |
20100202410 | Communication System - A source eNB determines whether an X2 interface is established between the source eNB and a target eNB when the source eNB performs a handover of a UE under the control of the source eNB to the target eNB. When the X2 interface is not established between the source eNB and the target eNB, the source eNB inquires with an address management node about the IP address of the target eNB. Upon receipt of the IP address of the target eNB from the address management node, the source eNB accesses the target eNB using the IP address and establishes the X2 interface. After establishing the X2 interface, the source eNB performs a handover of the UE to the target eNB. | 08-12-2010 |
20100296399 | WIRELESS BASE TRNSCEIVER STATION, COMMUNICATION SYSTEM, AND DATA TRANSFER METHOD - A wireless base transceiver station that transmits and receives data to and from an external device via fixed-line communication and transmits and receives data to and from a mobile station via radio communication. The wireless base transceiver station includes a radio communication unit configured to measure radio quality in a radio zone based on an error rate of data received from the radio zone, and a fixed-line communication unit configured to measure the amount of data flow in a fixed-line zone to perform flow control on data in the fixed-line zone. The wireless base transceiver station includes a control unit configured to control the flow control performed by the fixed-line communication unit, based on the amount of data flow in the fixed-line zone and the radio quality in the radio zone that have been measured by the fixed-line communication unit and the radio communication unit. | 11-25-2010 |
20110235564 | BASE STATION APPARATUS AND METHOD FOR DELIVERING MULTICAST SIGNAL - A base station apparatus includes a receiver, a transmitter, a determiner, and an instruction sender. The receiver receives a multicast signal. The transmitter transmits the multicast signal to a mobile station apparatus. The determiner determines, in accordance with a status of communication with the mobile station apparatus, whether the transmission of the multicast signal is needed. The instruction sender transmits, in accordance with a result of the determination, an instruction signal indicating whether to join a group of destinations of the multicast signal to a distribution apparatus for distributing the multicast signal. | 09-29-2011 |
20120108231 | BASE STATION, DETECTION DEVICE, COMMUNICATION SYSTEM AND DETECTION METHOD - A base station includes: an interface that transfers user data; a processor that controls the base station in accordance with a process including: obtaining a period of time from when a transfer unit receives the user data to when the interface transmits the user data; and detecting an abnormality in the interface based on the period of time. | 05-03-2012 |
