  • Method for transmitting collision-free messages in a digital selective call signaling protocol
    Patent number: 6469997
    Abstract: A plurality of transceivers (114) each include a transceiver circuit (409), and a processing system (412) coupled to the transceiver circuit. A periodic communication cycle is divided into a plurality of frames, each frame having a predetermined interval. Each of the plurality of frames in turn is subdivided into first and second portions (301, 303), whereby the second portion is used by the transceivers for requesting access to a communication medium (113). The second portion is further subdivided into a plurality of time slots, each time slot having a duration equal to or greater than a predetermined propagation delay of a signal transmitted between transceivers. Each of the transceivers is assigned to a corresponding one or more of the time slots.

  • Method in a selective call radio for ensuring reception of advertisement messages
    Patent number: 6031467
    Abstract: An SCR (122) that receives personal messages and corresponding advertisement messages, includes a receiver (304), memory (310), presentation circuit (313) and processor (308). The processor is adapted to cause the receiver to receive a personal message (402), to determine whether a corresponding advertisement message has been previously stored in the memory (404), and in the event the corresponding advertisement message is not found, cause (406, 410) the presentation circuit to present the personal message to a user of the SCR. Additionally, the processor causes the presentation circuit to present a warning (412) to the user that the SCR must receive the corresponding advertisement message within a predetermined time.

  • Communication transceiver providing unscheduled acknowledge back responses and method therefor
    Patent number: 5691709
    Abstract: A communication transceiver (510) having a receiver (704), a controller (714) and a transmitter (710), is used for generating an unscheduled acknowledge back response. The receiver (704) receives an address and a color code identifying the cell transmitter (506) transmitting the address during a first scheduled time interval (212). The controller (714) selects, in accordance with the address received, a reserved response time slot from a predetermined number of reserved response time slots occurring during a second scheduled time interval. The transmitter (710) then transmits the unscheduled acknowledge back response during the reserved response time slot (224) selected.
