Abstract

Methods, systems, and computer-readable media provide for adapting a quality of service mechanism based on feedback. A condition that affects quality of service of a communications network is monitored. An adaptation of the quality of service mechanism is determined based on a change to the condition. The adaptation is implemented on the communications network to improve the quality of service.

Claims

1. A method for adapting a quality of service mechanism based on feedback, comprising:

monitoring a condition that affects quality of service of a cellular network, the condition comprising a radio frequency link condition of a first radio frequency link between a cellular tower and a first cellular device in the cellular network;

identifying a change to the radio frequency link condition that decreases a first quality of service associated with the first cellular device;

determining whether the change to the radio frequency link condition falls below a threshold; and

in response to determining that the change to the radio frequency link condition falls below the threshold, terminating a second radio frequency link between the cellular tower and a second cellular device in the cellular network to free a cellular resource and allocating the cellular resource to the first cellular device, wherein terminating the second radio frequency link decreases a second quality of service associated with the second cellular device and reallocating the cellular resource from the second cellular device to the first cellular device increases the first quality of service associated with the first cellular device;

wherein monitoring a condition that affects quality of service of a cellular network comprises monitoring signal level between the cellular tower and the first cellular device, a noise level between the cellular tower and the first cellular device, and a data loss level between the cellular tower and the first cellular device.

2. A system for adapting a quality of service mechanism based on feedback, comprising:

a memory for storing a program containing code for adapting a quality of service mechanism based on feedback;

a processor functionally coupled to the memory, the processor being responsive to computer-executable instructions contained in the program and operative at least to;

monitor a condition that affects quality of service of a cellular network, the condition comprising a radio frequency link condition of a first radio frequency link between a cellular tower and a first cellular device in the cellular network,

identify a change to the radio frequency link condition that decreases a first quality of service associated with the first cellular device,

determine whether the change to the radio frequency link condition falls below a threshold, and

in response to determining that the change to the radio frequency link condition falls below the threshold, terminate a second radio frequency link between the cellular tower and a second cellular device in the cellular network to free a cellular resource and allocate the cellular resource to the first cellular device, wherein termination of the second radio frequency link decreases a second quality of service associated with the second cellular device and reallocation of the cellular resource from the second cellular device to the first cellular device increases the first quality of service associated with the first cellular device;

wherein to monitor a condition that affects quality of service of a cellular network, the processor is further operative at least to monitor a signal level between the cellular tower and the first cellular device, a noise level between the cellular tower and the first cellular device, and a data loss level between the cellular tower and the first cellular device.

3. A non-transitory computer-readable medium having instructions stored thereon for execution by a processor to provide a method for adapting a quality of service mechanism based on feedback, the method comprising:

monitoring a condition that affects quality of service of a cellular network, the condition comprising a radio frequency link condition of a first radio frequency link between a cellular tower and a first cellular device in the cellular network;

identifying a change to the radio frequency link condition that decreases a first quality of service associated with the first cellular device;

determining whether the change to the radio frequency link condition falls below a threshold; and

in response to determining that the change to the radio frequency link condition falls below the threshold, terminating a second radio frequency link between the cellular tower and a second cellular device in the cellular network to free a cellular resource and allocating the cellular resource to the first cellular device, wherein terminating the second radio frequency link decreases a second quality of service associated with the second cellular device and reallocating the cellular resource from the second cellular device to the first cellular device increases the first quality of service associated with the first cellular device;

wherein monitoring a condition that affects quality of service of a cellular network comprises monitoring signal level between the cellular tower and the first cellular device, a noise level between the cellular tower and the first cellular device, and a data loss level between the cellular tower and the first cellular device.
