A method and system for adaptively allocating shared communication resources in response to an emergency event are disclosed herein. In one embodiment, the method includes identifying a response zoneassociated with an emergency event and dispatching emergency responders, andhaving communication devices-to the response zone. The dispatching procedure includes adjusting access of the emergency responder communication devices to shared communications resources. Adjusting access to shared communication resources includes identifying one or more of the emergency responder communication devices to be dispatched to the identified response zone and specifying a quality of service (QoS) priority level of at least one of the identified emergency responder communication devices. Adjusting access to shared communication resources further includes specifying a QoS priority level for communication devices located within the identified response zone.

Emergency dispatch management and prioritization of communication resources

A communication device (), communication node (), and method for transmitting a message are disclosed. The method includes calculating number of frames () in a message to be transmitted from the communication device. The method further includes determining transmission power () for the message based on the number of frames. The method further includes transmitting each frame of the message () using the determined transmission power.

Communication device, communication node, and method for transmitting a message

This method () adaptively sends control messages and a predetermined number of fast repeats of the control messages on the traffic channel of a mobile communication system. For a control message which has already been lost (), the system sends the control message again with a first number of fast repeats () if the traffic channel is operating at a full rate; and the system sends the control message with a second number of fast repeats if the traffic channel is operating at a subrate. The number of fast repeats is selectable. If the control message has not been previously sent and the traffic channel is operating at a subrate (), the system will send the control message with a third number of fast repeats ().

Method for adaptive channel signaling

An RF power fairness method () receives a request for supplemental channel resources (). If sufficient supplemental channel resources (time slots and data rates) are not available, the original request is modified (). If there is multiple call activity on the supplemental channel, RF power is calculated for each of the simultaneous calls on the shared channel (). If successful time slots and data rates are found, a grant message is returned from the time slot manager () to the base station (). If insufficient time slots and data rate power are determined, a deny request message is transmitted to the base station ().

Fairness method for supplemental channel resources

A method () schedules the utilization of the supplemental channel of a base station transceiver (-). This scheduling includes time slot assignment as well as data transfer rate per time slot. One method simply selects the next time slot with a maximum rate for the primary base station transceiver (). The method then selects the same time slot for each of the secondary links with the secondary base stations (). The data is then simply sent to each of the BTSs (-) for transmission to the mobile station (). In another alternative, a request is made for a supplemental channel usage for the primary link (). Then secondary links are selected for transmission to the mobile station () only if they provide additional diversity gain () and resources are available at the secondary link BTSs.

Scheduling method for supplemental channel resource

A method of selective need-based control message augmentation may include a network unit of a mobile communication system () generating a control message () for communication to a mobile unit (), determining a handoff state transition of the mobile unit, and determining a set of signal conditions for one or more legs of an active set associated with the mobile unit. Further, the network unit at least one of selectively fast repeating the control message and selectively increasing the power gain for the control message based on the handoff state transition and the set of signal conditions.

Method of selective need-based control message augmentation

A method for adaptive power control in a mobile communication system () determines () whether an RF loading factor () is greater than a threshold value. If the RF loading factor is above the threshold value, the method reduces call quality (). Next, a determination is made whether the RF loading factor is below a second threshold value (). If the RF loading factor is below the second threshold value, the call quality of the mobile communication system is increased ().

Adaptive power control method for cellular systems

A communications platform () assigns communication channels () to users based on a power level associated with the individual users. An available bandwidth for use by the communications platform () in segmented into a number of sub-bands using a bank of filters (). A number of independent communication channels () are then provided within each of the sub-bands using an appropriate multiple access scheme (e.g., code division multiple access). A power range is then specified for each of the sub-bands. When a communication connection is to be established, a power level associated with the connection is determined. One or more sub-bands are then identified that have power ranges encompassing the determined power level. A channel is then assigned to the communication connection from one of the identified sub-bands.

A satellite communications system ( ) provides for digital beamforming acquisition. The communications system ( ) has an antenna configuration ( ) for maintaining communications links with satellite networking equipment, and a signal processing system ( ) for processing signals resulting from the communications links. A beamforming subsystem ( ) dynamically forms traffic beams and overhead beams, wherein the overhead beams scan overhead areas of the satellite footprint. Overhead areas are defined by areas of the satellite footprint without active traffic channels. The beamforming subsystem ( ) includes a channel database configuration ( ) containing traffic channel input data and overhead channel input data. A beamforming processor ( ) converts the input data contained in the channel database configuration ( ) into traffic beams schedules and overhead beam schedules.

A communications unit determines that a wireless link between itself and a first communications network has degraded beyond acceptable limits (FIG. 2, ). The communications unit signals a second, unsynchronized, communications network during a pause in outgoing voice ( ) in order to acquire a channel and continue the call using the second network. When the second communications network indicates that sufficient resources are available, the communications unit transmits a Handover Trigger to the second network (FIG. 4, ). In response to the Handover Trigger, the first and second communications network establish a connection between each other ( ). When the connection has been established, the communications unit receives a channel assignment ( ) and continues the call using the resources of the second communications network.

A narrowband communication system provides wideband data services in a secondary service band. This limits the impact on primary services in peak traffic regions in that the primary service band is not required to download wideband data from a communication node (e.g., a satellite) to a mobile terminal. The narrowband communication system implements a handoff protocol ( ) that rate negotiates a channel bandwidth of an active connection ( ) to the amount of channels that are available in a new cell. The narrowband communication system preempts ( ) lower priority subscribers when a higher priority ( ) high-speed data terminal requires access to the system and a requested channel assignment is not available ( ). The complexity of a high-speed data terminal communication chipset is reduced by a receiver design that minimizes the range of frequencies that are required to be demodulated.
