摘要： In order to allocate frequency channels to transmitter units, the transmitter units are grouped in zones, each zone having one or more transmitter units (10, 20, 30) therein. A system controller (40) calculates a zone priority value which is a function of the zone's message traffic level and message latency. The zone priority value determines the order in which a zone is assigned a frequency channel. A channel priority value is calculated for each channel or sub-channel that can be accessed by the transmitter units (10, 20, 10) in the zone based on a probability of success and a mean quality margin value wherein the priority value of a channel determines the order in which an available channel is considered for assignment to a zone. A proposed channel is assigned to a given zone only if the proposed channel passes a channel quality check. The channel quality check may be based on co-channel and adjacent channel interference values. Alternatively, the channel quality check may be based on a determination of whether a channel proposed for assignment to a given zone is currently in use by another zone that is correlated with the given zone. Zones are merged and divided in order to provide increasing system capacity and better channel quality as the customer demands grow.

摘要： 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 bandwidth to determine whether (124) a frequency channel is free or 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.

摘要： A communication system includes a plurality of organizational layers, a plurality of portable communication units, and a plurality of base stations. Each layer comprises a plurality of nodes. The plurality of nodes includes a plurality of base stations in the first layer, and a plurality of communication services nodes organized into higher layers. Each communication services node includes a database possibly containing information on the locations of one or more portable communication units. The databases constitute a distributed database containing the necessary and sufficient information on the locations of some of the portable communication units within the system, such that any active portable communication unit in its service area will be located using the most direct route. A tracing strategy is realized by the transmission of control messages informing the system of a moving portable communication unit's location. The system tries to set up a connection to the home address of the called portable communication unit, unless some information is found along the path to the home address of the called unit. In case there is information on the called unit its location is indicated by the address chain in the distributed database.

摘要： A non-real time messaging system (200) for targeting messages to a subscriber unit (222) comprises a synchronized profile of where a subscriber unit should be located (a predetermined base transmission area for transmission of messages to the subscriber unit) maintained between a controller (212) and the subscriber unit. The subscriber unit detects when the subscriber unit is not within the receiving range of a predetermined base transmission area, informs the controller and the controller directs subsequent transmissions to an area identified by the subscriber unit and otherwise transmits subsequent messages to the predetermined base transmission area. The system further includes a plurality of base receivers (217) coupled to the controller for receiving transmissions from the subscriber units and allowing the controller to detect when the subscriber unit is not within the receiving range of a predetermined base transmission area.

摘要： A base station (21, 22, 23) in a radio communication system (20) comprises a channel allocator (62) for allocating communication channels in accordance with a fully distributed dynamic channel allocation method. The channel allocator accesses a Preferred Channel List (PCL) (64) to allocate the communication channels. The PCL ranks channels (116) in accordance with the occurrence of prior events on the channels (112), such as interrupted calls (122), blocked call setup requests (118), and calls successfully completed (106) and in regards to the mean quality margin (110) and the current channel quality (114). The channel allocator (62) allocates (140) the first available channel (128) in the PCL having a free timeslot (132) and with good current channel quality (136). Alternatively, the channel allocator (62) allocates communication channels in accordance with an optimal dynamic channel allocation method. A list of channels assigned to the base station is updated by removing channels (372) that are locally heavy loaded (366) and in poor quality (370) and by adding channels (390) if the channels are locally heavy loaded (384), and in good quality (394) for a period of time (392). Unassigned channels may be borrowed (388) if they are in good quality (382), are in a locally lightly loaded period (384), and have been idle for a predetermined period of time (386). The assigned channels of the base station (340) are allocated first (356, 360), with the borrowed channels being allocated (350) when no assigned channels are available (340).

摘要： A selective call receiving device (10) such as a pager is controlled to dynamically change a base frame assigned to the device and subsequent control frames derived therefrom. The time that the device is operative to look for its address in a received signal can thus be dynamically changed to improve the efficiencies of a mixed systems environment without substantially reducing the battery life of the selective call receiving device (10). In two embodiments of the invention a new base frame for the device is derived from an originally assigned base frame that is stored in the selective call receiving device. In another embodiment, a new base frame for the device is derived from the device's address along with frame management information that is received by the selective call receiving device.

摘要： A system and method are shown 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 registers. An inbound preferred home subsystem list is also stored in the memory (77). In order to register to the integrated system, the subscriber unit identifies the most preferred outbound subsystem that covers the current location of the subscriber unit as its outbound home subsystem. If the outbound home subsystem is a two-way subsystem having an inbound channel accessible by the subscriber unit, the subscriber unit uses the inbound channel of the outbound home subsystem to communicate the registration information to the integrated system. If the outbound home subsystem is a one-way subsystem, the subscriber unit utilizes the inbound preferred home subsystem list to identify the most preferred inbound subsystem covering the current location of the subscriber for use in communicating the new registration information to the integrated subsystem.
