Two-way radio paging system having base station and mobile station implementing two-way communication of transmission reception

摘要

In a two-way radio paging system whose communication efficiency is improved, when a mobile station (2) becomes incapable of transmitting, unnecessary communication is not repeated between a transmission base station (1) and a reception base station (3). When a state is noticed that where it is capable of transmitting from the mobile station (2), the transmission base station (1) transmits calling-signal to the mobile station (2). The mobile station (2) receives the calling signal, before transmitting reception response toward the reception base station (3). The reception base station (3) receives the reception response. One communication is completed. When the reception base station (3) failed to receive the reception response, the transmission base station (1) transmits again calling-signal. This is repeated until the reception base station (3) succeeds in receiving the reception response from the mobile station (2). When a state is noticed that where it is difficult to continue transmission from the mobile station (2), the side of base station causes subsequent communication processing to limit to calling transmission from the transmission base station (1) to the mobile station (2). The reception base station (3) does not receive the reception response from the mobile station (2) to complete one communication.
