  • Patent number: 6826400
    Abstract: A portable communications subscriber unit operates as a data transfer terminal as well as an analog cellular telephone M-ES. Two modes of operation, an analog cellular communication mode and a Cellular Digital Packet Data (CDPD) mode, are available in the subscriber unit. The subscriber unit distinguishes between paging signals indicative of a CDPD mode of communication and those indicative of an analog cellular mode of communication. The subscriber unit automatically preempts CDPD communications in favor of analog cellular communications such as those carried out in an AMPS system. The present inventive method enables the subscriber unit to remain registered in the CDPD communication system using a CDPD “sleep mode” while performing activities on the AMPS system. Another aspect of the present invention facilitates the automatic switching of subscriber unit displays to correspond to the communication system with which the unit is presently communicating.

  • Patent number: 6816736
    Abstract: In a unique paging time slot format, each of the allocated paging time slots occurs periodically and is split into several prescribed paging time slots including at least one first type paging time slot having a relatively short duration and at least one second type paging time slot having a longer duration. The at least one first type paging time slots is of relatively short duration and transports an indication whether a particular associated wireless terminal was paged. The second type paging time slot is of longer duration than the first type time slot and transports the entire paging message. Specifically, a wireless terminal that is normally in a standby mode only has to enter a monitor mode, i.e., “wake up”, to monitor the relatively short first type paging time slot to determine whether it has been paged.
