Abstract: A paging system which provides both individual and information services includes a transmitter for transmitting page call address and data periodically in batches, and a population of battery saver paging receivers for receiving the transmitted call information. Each transmission batch comprises a synchronization code followed by a predetermined plurality of sequential frames. Each subscribing receiver searches for its individual service address in a first designated frame of each batch of a transmission period, and in addition, searches for its information service address in a second designated frame of a designated batch of a transmission period. Individual and information service data messages are obtained from frames subsequent the frame at which their respective address is found.

Abstract: A receive signal quality estimate is produced in a subscriber unit (SU) located in a given geographic area (26) covered by a wireless communication system (10) wherein a base station (12) transmits downlink signals in a group of successive time frames to a set of geographic areas (24) including the area (26) in which the SU is located, and each of the time frames has signals aimed at a corresponding one of the areas (26). A receiver in the SU is activated to listen over a determined listening interval that at least partly coincides with the group of successive time frames. A signal strength of at least one downlink signal received by the SU receiver during the listening interval is measured, and a receive signal quality estimate is indicated at the SU based on a result of the measuring step. In one embodiment, during a signal strength measurement, received data bits are reproduced as audible clicks the volume of which varies in proportion to received signal quality conditions.

Abstract: A portable communication device (150, 170, 175, 200) is responsive to an uplink change to determine whether the uplink change is practicable (305, 405, 505). If the uplink change is determined by the device to be practicable, the uplink change will be permitted by the device. If the uplink change is determined by the device to not be practicable, alternatives are evaluated (320, 420, 520). A network (102) upon determining that a portable communication device (150, 170, 175, 200) requires an uplink power change, transmits (630) the power change request to the portable device. Responsive to the power change request, the network receives from the device a data allocation change (640) associated with said power change request. The network transmits an updated uplink channel allocation assignment if available.

Abstract: A selective call receiver (5) has a programmable baud detector (12, 14) which is programmed (30) to test (33) for an absence of a paging signal having a predetermined baud rate at a first falsing rate and then programmed (36) to test (38) for either the presence or absence of the signal at a second baud rate lower than the first falsing rate, wherein samples from the first test (33) are also used in the determination made by the second test (38).

Abstract: A paging system which provides both individual and information services includes a transmitter (2) which transmits page call address and data periodically in batches to subscribing paging receivers (4). Each batch comprising a synchronization code followed by a predetermined plurality of sequential frames. Each paging receiver (4) searches for both its individual service address and a first information service address in its corresponding assigned frame of each batch of a transmission period, and in response to reception of the first information service address, searches for a second information service address in a designated common frame of each batch of a transmission period. Individual and information service data messages are obtained from frames immediately subsequent the frame in which the respective individual and second information service addresses are found.

Abstract: A radio communication system (5) includes a transmitting unit (1) coupled to at least one controller (6). The controller (6) is adapted to subdivide the SCR's (selective call receivers) (2) into SCR groups, assign the SCR groups to supergroups, and assign a selected number of message frames (216) and message intervals (208) to each SCR group in each supergroup. A supergroup is then selected, and included in an acquisition group message. The supergroup is for directing SCR's (2) targeted to receive the acquisition group message to monitor messages during the message reception interval (203) according to the supergroup. The controller (6) then invokes the transmitting unit (1) to transmit the acquisition group message to the SCR's (2). Messages target for specific SCR's (2) are then generated, and transmitted by way of the transmitting unit (1) according to the supergroup selected. The targeted SCR's (2) receive the messages according to the supergroup received.
