Abstract: A two-way wireless selective call communication system (20) using a synchronous time division multiplex communication protocol transmits messages divided into a plurality of data units (120, 126, and 128) from a plurality of selective call transceivers (32) to a paging terminal (33) during time slots (78), the number of data units and the time slots are set by the paging terminal controller (26) based on information, including size of the message information, received in an unscheduled transmission from each of the plurality of selective call transceivers. The paging terminal transmits to a selective call transceiver a multi-bit acknowledgement message having a one-bit acknowledgement for each of the plurality of data units. A selective call transceiver re-transmits data units not recovered by the terminal based upon content of the acknowledgement message. More than one selective call transceiver transmit during a one-time slot set by the terminal.

Abstract: A method for re-establishing communication between a base station (102) that transmits on a forward channel, and a subscriber unit (108) that has temporarily lost the forward channel, uses the concept of a re-registration interval. The base station (102) transmits, to subscriber units (106, 108) in its area, a signal indicating the duration of a re-registration interval. A subscriber unit that has temporarily lost the forward channel determines whether the duration of such loss exceeds the re-registration interval. If the interval is exceeded, the subscriber unit sends a re-registration signal to the base station on a reverse channel. A selective call transceiver (400) is programmed to operate as a subscriber unit that uses the re-registration interval.

Abstract: A communication system (100) provides minimum transmission delay for message delivery to communication transceivers (510) includes a plurality of transmission cells (102, 104) which include one or more receivers (512) and a transmitter (506) and which define geographical transmission areas. The transmitter (506) transmits an address identifying the communication transceiver (510) for which a message is intended and a color code signal identifying the transmitter (506) during a first scheduled transmission time interval (212). At least one receiver (512) located within the transmission cells (102, 104) receives an acknowledgment signal including the address and color code signal generated by the communication transceiver (510) during a second scheduled transmission time interval (216). The transmitter (506) identified by the color code signal transmits the address and message during a transmission frame (110) designated by the color code signal during which time the address and message are received by the communication transceiver (510).

Abstract: A system controller (102) is used in a communication system (100) which has a set of inbound channels. The system controller (102) includes a processing system (204) for generating a first message which is transmitted to selective call devices (106). The first message includes a subset identifier which identifies an ALOHA subset of the set of inbound channels for use by a set of the selective call devices (106). A selective call device (106) includes a transmitter (708) and a processing system (710). The processing system (710) identifies the ALOHA subset of the set of inbound channels, and generates a second message and couples the second message to the transmitter (708) using an ALOHA protocol on an inbound channel which is in the ALOHA subset of the set of inbound channels when the second message is a first type. The transmitter (708) transmits the second message.
