Abstract

An architecture, system and associated method for dynamic coordination of radio resource usage in a network environment. In one aspect, a relay communication method comprises detecting, by a first wireless mobile device, sensory data associated with multiple radio channels relative to at least one radio element in a sensing area of the first wireless mobile device. If the first wireless mobile device is out of range of a wide area cellular network, a short-range wireless communication path is established with a second wireless mobile device having a wide area cellular communication connection. The sensory data is transmitted by the first wireless mobile device to the second wireless mobile device for reporting to a network element via a wide area cellular network serving the second wireless mobile device.
