摘要： PROBLEM TO BE SOLVED: To provide a means which automatically decides message transmission times and performs transmissions according to change of radio quality. SOLUTION: A base station has a radio quality measurement unit which measures radio quality between the base station itself and a terminal, and a message transmitting/receiving unit which has a function to transmit messages multiple times according to the radio quality. The message transmitting/receiving unit analyzes the radio quality using the data measured by the radio quality measurement unit, and calculates transmission times of the messages. Moreover, upon transmitting messages multiple times, it transmits making sequence numbers in headers attached to the messages as the same. The radio quality measurement unit measures radio wave quality itself between the terminal and the base station, or data necessary for deciding the quality of the radio wave, and transmits the data to the message transmitting/receiving unit.

摘要： PROBLEM TO BE SOLVED: To automatically and properly select a link used in each hop of the communication path and an adaptation at the boundary between management domains or layers according to service type and maintenance requirements without complicating a control sequence in an MPLS (Multi-Protocol Label Switching Architecture)/GMPLS (Generalized Multi-Protocol Label Switching Architecture) network. SOLUTION: Firstly, a means for appending an identifier of a service to be provided and attributes of the service to a communication path establishment control message to request to establish the path is installed in a source node. Secondly, a means for determining the maintenance requirements and adaptations of the communication path based on the service identifier and/or the service attribute is installed in each node. Thirdly, maintenance attributes of network resources are compared with the maintenance requirements to determine links and nodes through which the communication path passes. The determined links, nodes and adaptations are set as action parameters of a switch unit and/or an interface unit. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To prevent communication at a high bit rate from becoming difficult by interference of radio waves emitted from base stations in a boundary region in an HDR system. SOLUTION: An antenna module 19-1 has a plurality of antenna elements. A receiver high-frequency circuit 19-3 synthesizes signals according to an antenna directivity having a desired beam pattern. A demodulator 19-5 selects one of the received signals from wireless terminals and determines transmission beam direction information for use in directing the beam in the selected direction. A weight controller 19-13 generates weight coefficients for setting of the beam patterns and transmission beam directions and produces transmission time slots according to a table listing the relations of the transmission beam directions and the time slots for use in the beam radiation in those directions. A down-link fixed beam-forming circuit 19-11 and a modulator 19-10 control the antenna module 19-1 using the generated beam pattern, beam direction and transmission time slots to transmit the down-link signal.

摘要： PROBLEM TO BE SOLVED: To provide base stations which can gradually accommodate T1 leased lines in accordance with radio traffic volume without damaging an operating ratio, and routers for putting the base stations together, in a radio system having a plurality of T1 leased lines.
SOLUTION: The router acquires a multi-link group number of a base station from a line information of a multi-link PPP packet received from the base station, and automatically calculates an IP address from the multi-link group number and a multi-link group number of the router. Further, the router gives the automatically calculated IP address to a T1 line of the router, and also notifies the base station of the IP address.
