RADIO RESOURCE ALLOCATION CONTROL METHOD

Japanese Patent JP3422692

B2

PROBLEM TO BE SOLVED: To prevent the deterioration of the using efficiency of a radio resource by connecting plural radio terminals through radio lines with one radio base station, allowing the radio terminals to share radio frequencies among the radio terminals, and directly transmitting the allocation of radio channels to the radio terminals by using the radio channels.
SOLUTION: A transmission and reception branching filter 2 operates a switching operation for introducing a radio signal captured by an antenna 1 to a receiver 5, and for switching a radio signal from a transmitter 4 to the antenna 1. A frequency synthesizer 3 operates channel switching by switching the transmission frequencies of the transmitter 4 or changing the frequencies of the local transmitter of the receiver 5 and switching the reception frequencies. When a message detecting part 6 detects a channel allocation request signal from among the reception signals of the receiver 5, it informs a control part 7 of the detected result. The control part 7 controls each part based on this signal, and transmits an assignment message by using an assignable empty channel from the using situation of a resource and the situation of the presence or absence of interference.
