    摘要： When a radio resource allocation channel transmitted from a radio base station (eNB) at a discontinuous reception timing satisfies a specific condition, a mobile station (UE) is configured not to reactivate a predetermined timer, even though the mobile station (UE) detects that the mobile station identifier allocated to the mobile station (UE) is included in the radio resource allocation channel transmitted from the radio base station (eNB), before the predetermined timer expires.

    摘要： A CDMA mobile communications system and its random access control method and base station are provided that can reduce the probability of failing to detect the preamble. A preamble detector (12) measures the signal-to-interference power ratio of a received preamble after RAKE combining, and makes a decision on whether to authorize a mobile station to transmit a message or not by comparing the detection result with the threshold value. Receiving from the preamble detector (12) the decision result indicating that the measurement value is equal to or greater than the threshold value, a CPU (14) causes a transmitter to transmit a transmission control signal authorizing a mobile station sending the preamble to transmit the message. In contrast, when the decision result indicates that the measurement value is less than the threshold value, the CPU (14) does not authorize the mobile station to transmit the message.
