Abstract

Abstract A two-way communication system is used for performing dynamic channel control. The two-way communication system comprises a base transceiver (102) and a plurality of selective call transceivers (122). The base transceiver (102) includes a plurality of base stations (116) controlled by a controller (112). The base transceiver (102) transmits query signals to the selective call transceivers (122) to prompt communication. The selective call transceivers (122) measure the signal quality of signals transmitted by the two-way communication system and transmit in return signal quality measurement data to the base transceiver (102) for analysis. The base transceiver (102) dynamically adjusts the signal quality of signals to be received by the selective call transceivers (122) in order to substantially reduce the noise interference that the selective call transceivers (122) experience.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 231 words
A two-way communication system comprising: a plurality of base transmitters for transmitting signals; at least one base receiver for receiving signals; a controller coupled to the at least one base receiver and the plurality of base transmitters for coordinating communication by the at least one base receiver and at least one base transmitter, the controller comprising a memory; at least one selective call transceiver comprising a transmitter, a receiver and a processor, the processor programmed for measuring signal quality of signals transmitted by the at least one base transmitter and received by the receiver of the at least one selective call transceiver and generating a signal quality measurement thereof for transmission via the transmitter of the at least one selective call transceiver to the at least one base receiver, said signal quality measurement identifying a cause and degree of signal interference; and wherein the at least one base receiver receives the signal quality, measurement for storage in the memory of the controller, and wherein the controller is programmed to adjust a frequency reuse plan affecting those base transmitters of the plurality of base transmitters that contribute to co-channel interference of the at least one selective call transceiver, thus the controller dynamically adjusts signal quality of signals to be received by the receiver of the at least one selective call transceiver in accordance with the signal quality measurement stored in the memory.
Claim 2
Dependent Claim 231 words
A two-way communication system comprising: a plurality of base transmitters for transmitting signals; at least one base receiver for receiving signals; a controller coupled to the at least one base receiver and the plurality of base transmitters for coordinating communication by the at least one base receiver and at least one base transmitter, the controller comprising a memory; at least one selective call transceiver comprising a transmitter, a receiver and a processor, the processor programmed for measuring signal quality of signals transmitted by the at least one base transmitter and received by the receiver of the at least one selective call transceiver and generating a signal quality measurement thereof for transmission via the transmitter of the at least one selective call transceiver to the at least one base receiver, said signal quality measurement identifying a cause and degree of signal interference; and wherein the at least one base receiver receives the signal quality, measurement for storage in the memory of the controller, and wherein the controller is programmed to adjust a frequency reuse plan affecting those base transmitters of the plurality of base transmitters that contribute to co-channel interference of the at least one selective call transceiver, thus the controller dynamically adjusts signal quality of signals to be received by the receiver of the at least one selective call transceiver in accordance with the signal quality measurement stored in the memory.
Claim 3
Dependent Claim 39 words
The two-way communication system of claim 1, wherein the controller is programmed to adjust a power plan transmitted by at least one of the plurality of base transmitters in accordance with the signal quality measurement stored in the memory.
Claim 4
Dependent Claim 169 words
A base transceiver comprising: at least one base transmitter for transmitting signals; at least one base receiver for receiving signals; a controller coupled to the at least one base receiver and a plurality of base transmitters including the at least one base transmitter for coordinating communication by the at least one base receiver and the at least one base transmitter, the controller comprising a memory; and wherein the at least one base receiver receives a signal quality measurement from at least one selective call transceiver for storage in the memory of the controller, said signal quality measurement identifying a cause and degree of signal interference, and wherein the controller is programmed to adjust a frequency reuse plan affecting those base transmitters of the plurality of base transmitters that contribute to co-channel interference of the at least one selective call transceiver, thus dynamically adjusting signal quality of signals to be received by the at least one selective call transceiver in accordance with the signal quality measurement stored in the memory.
Claim 5
Dependent Claim 169 words
A base transceiver comprising: at least one base transmitter for transmitting signals; at least one base receiver for receiving signals; a controller coupled to the at least one base receiver and a plurality of base transmitters including the at least one base transmitter for coordinating communication by the at least one base receiver and the at least one base transmitter, the controller comprising a memory; and wherein the at least one base receiver receives a signal quality measurement from at least one selective call transceiver for storage in the memory of the controller, said signal quality measurement identifying a cause and degree of signal interference, and wherein the controller is programmed to adjust a frequency reuse plan affecting those base transmitters of the plurality of base transmitters that contribute to co-channel interference of the at least one selective call transceiver, thus dynamically adjusting signal quality of signals to be received by the at least one selective call transceiver in accordance with the signal quality measurement stored in the memory.
Claim 6
Dependent Claim 38 words
The base transceiver of claim 3, wherein the controller is programmed to adjust a power plan transmitted by at least one of the plurality of base transmitters in accordance with the signal quality measurement stored in the memory.
