An LTE wireless communication system includes an LTE base station, and mobile wireless communications devices. Each mobile wireless communications device exchanges video data with another mobile wireless communications device via the LTE base station and by sending at least one of a PTV request and an RTV request to the LTE base station. The LTE base station is configured, when network traffic is below a threshold value, to allocate bandwidth for a PTV connection between a given mobile wireless communications device and a given other mobile wireless communications device, and, when the network traffic exceeds the threshold value, to allocate bandwidth for an RTV connection between the given mobile wireless communications device and the given other mobile wireless communications device.
