Abstract

An Intelligent Transport System enabled cellular mobile network, comprising an infrastructure including a number of base stations (5), and a number of vehicles (4) being equipped with both vehicle-to-vehicle and vehicle-to-infrastructure communication facilities, wherein particular events function as trigger for said vehicles (4) to send event specific warning messages to their serving base station (5a) within said infrastructure, is characterized in that said base stations (5) comprise an evaluation module being configured to analyze and categorize warning messages received from any of said vehicles (4) according to predefinable criteria, and to estimate the number of vehicles (4) that may be affected by the event related to a warning message, and a control module for performing uplink radio resource adaptation dependent on said warning message's category and said estimated number of affected vehicles (4).
