Abstract:
A radio communication permission control apparatus includes a request receiving section, a reply section, an estimating section, a storage section, a determining section and a priority section. The request receiving section receives communication start request signals from requesting communication terminals. The reply section replies to each of the requesting communication terminal based on priority levels of the requesting communication terminals, a response indicating whether or not to permit communication start every time the request receiving section receives each of the communication start request signals. The priority section increases the priority levels for the prohibited communication terminals.
Abstract:
A relay device according to the present invention includes an uplink signal relaying unit that performs an uplink signal relaying operation that amplifies an uplink signal transmitted through an uplink channel from a mobile station and re-transmits the amplified uplink signal to a base station; a frequency information acquisition unit that acquires frequency information that represents a frequency band that said mobile station uses for the uplink channel periodically or at predetermined timings; an uplink signal detection unit that determines whether or not the average reception power of the uplink signal in the frequency band represented by the frequency information acquired by said frequency information acquisition unit exceeds a predetermined threshold; and a control unit that controls the uplink signal relaying operation performed by said uplink signal relaying unit based on a determined result of said uplink signal detection unit.

Abstract:
When an information storage unit of a radio base station setting device includes information related to a CDMA radio base station device which has supplied discrimination information, the radio base station setting device deletes the information from the information storage unit, and estimates the location of the CDMA radio base station device. The radio base station setting device reads communication configurations for existing radio base station devices installed around the estimated location from the information storage unit. The radio base station setting device determines communication configurations for the CDMA radio base station device based on the read communication configurations for the existing radio base station devices, and the estimated location.
Abstract:
Each mobile terminal and/or radio base station determines whether a radio base station transmits radio waves of excessive power. Based on determination results obtained by a plurality of mobile terminals and/or radio base stations, a radio-system management server determines whether a certain radio base station transmits radio waves of excessive power. When the certain radio base station transmits radio waves of excessive power, the radio-system management server instructs the certain radio base station to forcefully stop its radio transmission by transmitting a forced transmission-stop control message to the radio network controller that controls the certain radio base station.
Abstract:
The random access communication method according to the present invention includes a mobile station transmitting a transmission continuation request signal which requests a continuation of transmission of random access data to a base station during transmission of the random access data, the base station judging, upon receiving a transmission continuation request signal from the mobile station, whether or not to permit a continuation of transmission of the random access data depending on the current communication situation, the base station transmitting a transmission continuation permission signal or a transmission continuation rejection signal to the mobile station depending on whether or not to permit the continuation of transmission of the random access data, and the mobile station continuing, upon receiving the transmission continuation permission signal from the base station, transmission of the random access data.

Abstract:
A path detector (100) provides statistics of rates at which preamble signals are detected within a predetermined time period. For a delay amount segment where the detection rate is low, the sampling rate of correlation value calculation is reduced, and the number of correlator sets used for the preamble signal detection is reduced. Correlator sets made available by that reduction are used to detect message signal paths, thereby raising the operating rate of the RAKE receivers of a decoder (200) to improve the throughput of the message signals. Further, the statistics of the rates of preamble signal detections are periodically updated, and when the preamble signal detection rate of the delay amount segment where the sampling rate was reduced becomes higher, the number of the correlator sets used for the preamble signal detection is increased so as to return the sampling rate to its original value.
