<P>PROBLEM TO BE SOLVED: To provide a radio base station capable of improving communication quality of a radio terminal which is in a long distance from the radio base station, and to provide a radio communication method. <P>SOLUTION: A control part 13 receives random access (Random Access, or RA) from a radio terminal, and checks distance information stored in a storage part 12 to check whether or not the radio terminal is a long distance terminal when a radio resource occupancy is lower than a threshold α. When the radio terminal is the long distance terminal, the control part 13 refers to a radio resource weighting value β stored in the storage part 12, and transmits AA_Pending to the radio terminal when the weighting value β is larger than a threshold γ. The radio terminal transmits the RA again after a predetermined period of time. When the RA is received from the radio terminal after the predetermined period of time, the control part 13 specifies another radio terminal to transmit access assignment (Access Assignment, or AA) to the radio terminal. The radio terminal which receives the AA performs TCH communication in the specified radio resource (channel) and opens a stream. <P>COPYRIGHT: (C)2012,JPO&INPIT |
