Patent ID: 7738438

Claim:
A radio base system multi-path connected to a plurality of mobile terminal devices via a plurality of paths being multiplexed to each of a plurality of slots being multiplexed in a time division manner, to transmit/receive signals, comprising: signal adjusting unit for performing an adaptive array process for performing multi-path connection to said plurality of mobile terminal devices; error detecting unit for detecting an error in a signal from the mobile terminal device connected to each of said plurality of slots; and control unit for, when a communication channel establishment request is sent from one of said plurality of mobile terminal devices, selecting one of said plurality of slots to determine if there is a mobile terminal device to which a communication channel is already connected for said for selected slot, allocating a channel to said one mobile terminal device if there is no mobile terminal device to which a communication channel is already connected for said selected slot, determining if multi-path connection is appropriate for said one mobile terminal device when there is a mobile terminal device to which a communication channel is already connected, permitting, when it is determined that multi-path connection is possible, channel establishment in accordance with a result of detection of said error detecting unit, and selecting, when it is determined that multi path connection is impossible, a subsequent slot sequentially.
