Abstract: The present invention aims at extending a talkable time allocated by a server at the user's will of the equipment. In a PoC service that implements a half duplex talk session using a packet communication among a plurality of equipments via a PoC server, the PoC server receives a talking time extend request from a user equipment 21 to which a floor is granted (step S801). Then, the PoC server grants the talking time extend request by determining that no floor take request is made by equipments except the user equipment 21 to which the floor is granted. Then, the PoC server transmits a talking time extend notification to the equipment to which the talking time extend request is granted (step S802).

Abstract: A method of detecting a position of a radio mobile station in radiocommunications, which is capable of accurately and simply finding the position of the mobile station. At a measuring point the mobile station measures the reception radio strength levels from a plurality of base stations and conveys the measurement results through the base station to a control station. The control station learns, through a neural network, the correlation between the reception radio strength levels and the position of the mobile station on the basis of the measurement results at a plurality of measuring points and the positions of the measuring points. Subsequently, when the mobile station communicates to the control station the reception radio strength levels measured at an arbitrary point, the control station estimates the position of the mobile station, causing those measurement results, on the basis of the correlation obtained through the learning.

Abstract: A bi-directional video signal transmission system is equipped with transmission lines having coupled upsteam and downstream segments. With the entire band of a RF signal being taken as a modulation frequency band, an image signal modulated to a frequency band and RF-multiplexed in the upstream segment is introduced into the downstream segment at the modulated frequency and is then branched to demodulate the same frequency band, thereby obtain one video signal transmission channel. In response to a request by a subscriber, a channel management section assigns and releases the transmission channels and further outputs a control command whereby a transceiver control section performs switching-control of the transmission frequencies to transceiver units.
