摘要： A hand-over control method is disclosed to control the change of connections between a radio communication terminal and a plurality of radio communication base stations for radio communication. The received power of a signal from a radio communication base station in a cell that that is subject to the influence of fading is likely to vibrate within a predetermined strength range. Even if a cell satisfies hand-over conditions, there is a greater likelihood that the cell is still subject to the influence of fading, if the received power is not exceeding this predetermined range The current received quality of a signal from a radio communication terminal in the cell is compared with last received quality of the signal from the radio communication base station when the radio communication terminal finished radio communication with radio communication base station. If the former quality is not higher than the latter quality by a predetermined level or more, the radio communication base station is determined to still be subject to the influence of fading, and hand-over is not performed. If, on the other hand, the former quality is higher than the latter quality by the predetermined level or more, the radio communication base station is determined not to be subject to the influence of fading, and hand-over is not performed.

摘要： The invention provides a transmission bit rate discrimination method and apparatus wherein, when a base station in a mobile communication which makes use of spectrum spreading performs transmission at a variable bit rate using four different transmission bit rates and repetitively transmits transmission symbols of a low transmission bit rate, a mobile station detects a rate of repetitions of received symbols and discriminates the transmission bit rate of received data simply. A received symbol sequence for one frame is inputted to shifters for shifting the received symbol sequence by one, three and seven symbol distances, respectively, and a correlation calculator for calculating an auto-correlation. The outputs of the shifters are inputted to correlation calculators for calculating cross-correlations, and results of the correlation calculations are inputted to a comparator, by which they are compared with reference to a result of the auto-correlation calculation to discriminate the transmission bit rate. A switch is switched in response to the discriminated transmission bit rate so that the received symbol sequence is sent out to one of Viterbi decoders which corresponds to the transmission bit rate.
