    摘要: A method in a communications receiver (20) for handling a selective call message comprises the steps of measuring a parameter of the selective call message (104, 116) and selecting whether to provide the selective call message to a display (118) or a communications port (106) in response to measuring the parameter of the selective call message (104, 116). The communications receiver (20) can function as either a pager or a radio frequency (RF) modem. A controller (66) determines the parameters of the message and operates the communications receiver (20) as a pager or as an RF modem in response to the parameters measured.

    摘要: A method and apparatus in a selective call receiver allow a user to receive maildrop message without losing access to previously received but unread maildrop messages in the same message slot. The selective call receiver comprises an address correlator (107) which determines whether received selective call signals comprise an individual or maildrop address assigned to the selective call receiver. A message memory (122) comprises an individual message portion (126) having an individual memory directory (127) and a maildrop message portion (128) having a maildrop memory directory (129). A processor (112) determines whether the decoded selective call message is an individual message or a maildrop message (204), determines whether a previously received maildrop message stored in the maildrop portion of the memory and having a maildrop address equivalent to the maildrop address of the decoded selective call message is "read" or "unread" (216), and provides identification information corresponding to the previously received one of the maildrop messages from the maildrop memory directory means to the individual memory directory means (222) if the previously received one of the maildrop messages is "unread".

    摘要: Briefly, according to the invention, a method (100) for updating the channel priority table in a receiver (300) having a signal condition table is disclosed. The receiver (300) is adapted to receive a carrier signal modulated with an information signal having a pre-determined format. The format of the information signal determines the priority of the channel the carrier signal is received on. The steps of the disclosed method include monitoring the carrier signal of the highest priority channel with activity, and periodically scanning (126 and 128) other channels including decoding of their information signals. The decoded information signal is compared to the condition table of the receiver in order to detect a higher priority carrier signal. The higher carrier signal is then monitored and the channel priority table is updated accordingly (120 or 112).

    摘要: A communication system (100) encodes and decodes information utilizing at least four modulation levels for transmitting the information as symbols representing symbol bits in symbol bit positions. At least one of the symbol bit positions exhibits an error rate higher than that of another of the positions. A processor (204) encodes (702) the information into an even number of code words and transmits the code words as an interleaved data stream. The processor (204) rearranges (706, 708) the transmission order of the code word bits in a predetermined way to form a modified transmission order such that the code words are transmitted (710) with substantially equal error rates. A receiver (110) receives and demodulates (712) the interleaved data stream to derive the code word bits, and then reorders (714, 716) the code word bits to undo bit modifications resulting from the modified transmission order, thereby restoring the code words. The receiver then decodes the code words to recover the information.

    摘要: A method (200) and apparatus (100, 402) are shown for determining whether first and second data messages in a communication system are duplicates. The method comprises forming (304) from the first and second data messages a corresponding pair of first and second message identifiers (120, 126). The identifiers (120, 126) comprise bits generated from first and second message characteristic values calculated (206) from portions (118, 124) of the first and second data messages. The method further comprises comparing 316 the first and second message identifiers (120, 126) to determine whether the first and second message identifiers (120, 126) are substantially equivalent to each other, substantially equivalent identifiers (120, 126) being indicative that the first and second data messages are duplicates.
