Abstract

PURPOSE:To attain smooth mobile radio communication by bringing a transmitter for a relay station into the transmission state by a reference station when transmission is started and bringing a transmitter for a mobile station into the transmission state after a timer set time. CONSTITUTION:When transmission start is given to terminals 8, 17 of the reference station, transmission start is given to the mobile station transmitter 4 and the relay station transmitter 13 via controller connection sections 5, 14, and a radio wave is irradiated from a mobile station antenna 1 and a relay station antenna 10 via antenna switching sections 2, 11. The radio wave is received by a reference station antenna 18 at the relay station and enters a receiver through an antenna switching section 19. A relay control section 22 uses reception information from the receiver 20 to apply transmission start to a mobile station transmitter 24, and a radio wave is irradiated from a mobile station antenna 26 to the mobile station via a switch section 25. Since a difference is given to the transmission start time between the transmitters 4 and 24 through the operation above, a timer 9 is applied when an input is given to the terminal 8 to retard the start of transmission for a prescribed time thereby making the transmission start identical to the transmitters 4 and 24.

、システム運用効率が悪く、また扱者の不安もあった。When transmitting to a mobile station using the same wave (breathtalk method), when the mountaintop relay station receives a radio wave (relay wave) from the base station, it puts the transmitter for the mobile station into a transmitting state based on the received information, and the mobile station It was a method to send radio waves to. In this method, there is a difference between the transmission time from the base station and the transmission time from the mountaintop relay station, which means that the inter-mobile station radio waves from the base station cause the relay station's mobile station receiver to enter the receiving state.
Next, the base station transmitter of the relay station enters the transmitting state, so
The mobile station was unable to open a call until the relay station started transmitting, resulting in poor system operation efficiency and concerns for operators.

Its purpose is to increase the efficiency of line usage and eliminate dishonesty on the part of operators.

When it receives the reception information of 0, it activates the transmitter for the mobile station to transmit, and transmits the information to the mobile station antenna 2 through the antenna switching section 25.
6, radio waves are emitted to the mobile station. In such an operation, there is a difference in transmission activation time between the mobile station transmitter 4 of the base station and the mobile station transmitter 24 of the relay station, so when a transmission activation input is received at the transmission activation input terminal 8 of the base station, the timer 9 is operated to delay the transmission activation input for a certain period of time so that transmission activation with the mobile station transmitter U of the relay station occurs within one hour.
