DISCRIMINATING-CALL SYSTEM AND ITS SECONDARY STATION

communications engineering. SUBSTANCE: discriminating-call system has its base stations 1 and 2 transmitting address code words at desired speed. High-speed autographic information, for example that of e-mail message type, is transmitted at speed exceeding that of address code word transmission. If it is simultaneously transmitting system, character-to-character interference may occur; in order to reduce effect of this interference when decoding autographic information and at the same time to prevent excessive expenditure of secondary-station batteries autographic information received by definite secondary station is stored and then aligned in other- than-real time. Mobile terminal can turn on transmitter for conveying acknowledgements or other response signals in the form of, say, extended-spectrum signals. Acknowledgement signals may be used for locating mobile terminal. EFFECT: enhanced speed of system using secondary station. 18 cl, 12 dwg
