METHOD FOR OPERATING MOBILE RADIOTELEPHONE IN A CDMA RADIOTELEPHONE SYSTEM AND CDMA RADIOTELEPHONE

摘要

BACKGROUND OF THE INVENTION The present invention relates to a mobile radio telephone code division multiplex in an access radio telephone system, which system base stations provide pseudo-random signals, a regular short PN sequence, and a long PN sequence, which is used as a short PN sequence envelope time indicator, which determines the offset of relatively slow and relatively high speed signals before the sleep mode step. c) sleep time is programmed using a relatively slow sleep time clock generator; (E) the timing of the mobile radiotelephone to the timing of exit from the sleep mode to the relatively slow clock and f) the sleep mode is synchronized with the time indicator. The present invention relates to a code division multiplexed CDMA radiotelephone for use in a process of code division multiplex access radiotelephone system, which provides base station signals, regular short PN sequences, and long PN sequences, which are used as short PN signal wrapper time indicators that produce a relatively slow signal, sleep time, for a radiotelephone. clock signal generator (205), short sequence PN signal generation matched with time signal of the radiotelephone system - a relatively fast clock signal from the PN signal generator to produce an oscillator synchronized with the time indicator, and one to the oscillator of the CDMA radiotelephone units that distinguish between fast and slow clock. also contains - its part is controlled by a relatively slow clock signal, in combination with the difference in the number of clocks and - the sleeping units of the radiotelephone are in synchronization with the CDMA system time indicator in synchronization, with a wake-up, relatively fast clock edge synchronizer (202). ŕ
