Abstract:
A battery-powered selective call transceiver (20), operating in two-way communication with an RF communication system (10), can be put in a power saving state. A user control (62) on the transceiver (20) allows a user to select the duration of a power saving interval. The transceiver (20) sends to the communication system (10) a signal requesting that the transceiver enter a power saving state for the selected interval. Upon receipt of an acknowledgment signal from the system, the transceiver enters the power saving state.
Abstract:
A system and method for registering a subscriber unit (10) in an integrated communication system having a number of subsystems (30, 50) that are capable of operating independently. The subscriber unit (10) stores in a memory (77) a list of outbound subsystems ordered according to the subscriber unit's preference for using the subsystem as a outbound home subsystem to which the subscriber unit (10) registers. An inbound preferred home subsystem list is also stored in the memory (77). In order to register to the integrated communicaton system, the subscriber unit (10) identifies the most preferred outbound subsystem that covers the current location of the subscriber unit (10) as its outbound home subsystem.
Abstract:
An etiquette controller (112) in a transmitter (14) in a first radio frequency (RF) communications system (10) enables radio frequency communications in a frequency bandwidth shared with heterogeneous RF communication systems (15). The etiquette controller (112) monitors the first RF signals in an isochronous frequency channel in a sub-band of the shared frequency badwidth to determine whether (124) a frequency channel is free of whether (130, 136) the frequency channel comprises a communication channel which is free. In addition, the etiquette controller (112) causes the RF transceiver (102) to transmit (148) a channel relinquishment signal, monitors (150) the isochronous frequency channel for a predetermined monitoring time, and determines (152) whether the isochronous frequency channel is then free for the channel access.
Abstract:
A system and method for selecting an outbound subsystem and an inbound subsystem to communicate between a subscriber unit (10) and an integrated communication system having a number of independently operating subsystems (30, 50). The subscriber unit (10) stores in memory (77) each of the different types of messages that it can handle, a list of the subsystems that can be used to communicate the message type wherein each list is ordered according to the subscriber unit's preference. When the subscriber unit receives control information identifying a particular type of message, the subscriber unit identifies at least one outbound subsystem for the received message type covering the area in which the subscriber unit is located. The subscriber unit then communicates this information to the integrated subsystem using an inbound channel of the most preferred identified subsystem. If none of the identified subsystems includes an inbound channel the subscriber unit identifies the most preferred inbound subsystem that the subscriber unit can access regardless of message type.
