Abstract: A cooperative paging system (10) and radio telephone system (15) combine to provide conventional delivery of short paging messages to a combination pager/radio telephone (40) via a first communication path, while a radio telephone link operating at a higher data rate is used to deliver large data messages to the pager/radio telephone (40). The radio telephone link is formed by a transceiver section (205) of the pager/radio telephone (40) coupling to a radio telephone base station (50,52) and calling up a paging terminal (32) of the paging system (10). The paging terminal (32) retrieves the large data messages from a temporary message memory (42) to deliver to the pager/radio telephone (40).

Abstract: PCT No. PCT/US87/00004 Sec. 371 Date Jun. 11, 1987 Sec. 102(e) Date Jun. 11, 1987 PCT Filed Jan. 2, 1987.A communication receiver is disclosed which can decode signals transmitted by radio frequency propagation. A programmable controller uses instructions in a non-volatile reprogrammable memory to decode and process the signals, and to output the information contained in the signals in a useable form. The controller also responds to predetermined signals by decoding and processing information for new decoding and operating instructions, and stores the data in a temporary memory. Logic circuitry responds to subsequent predetermined signals to enable selective reprogramming of the non-volatile reprogrammable memory by data stored in the temporary memory to alter the decoding characteristics of the receiver.

Abstract: A receiver (70) receives a transmitted signal having a periodic predetermined signal, a method and apparatus (99) detects a first predetermined signal. Power may be conserved during a portion of a subsequent predetermined signal. The subsequent predetermined signal is divided into at least a first and second portion. If the first portion is detected, the subsequent predetermined signal is considered detected and power is conserved for the second portion. If the first portion is not detected, the receiver remains active for the second portion in order to detect the subsequent predetermined signal.

Abstract: A microcomputer (104) having predetermined clock pulse frequency requirements receives pulses from a multiplying type frequency synthesizer (200) which utilizes a reference frequency less than the largest of the predetermined requirements. The synthesizer (200) is responsive to program instructions to generate clock pulse frequencies sufficient to satisfy the requirement for immediate execution of programmed tasks. As the execution requirements change, the synthesizer (200) responds to provide only the frequency required. Thus, the power dissipated by the entire microcomputer system is minimized.
