A method of controlling a network, for example a 5G network, including a subject user equipment, UE, and a target UE, the method comprising: obtaining respective operational information, for example a location, a speed, an acceleration and/or a heading and optionally, a size class, of the subject UE and of the target UE; calculating a time to collision, TTC, between the subject UE and the target UE; controlling the network, based on the calculated TTC. The method may comprise determining a safety focused UE mobility related key performance indicator, KPI. Obtaining the respective operational information may comprise sharing the respective operational information via one or more V2X messages. The method may comprise calculating respective trajectories using the respective operational information. Calculating the TTC comprises deriving a collision risk distance and calculating the TTC using the derived collision risk distance. The method may comprise estimating a TTC accuracy and/or a TTC confidence. Obtaining the respective operational information may comprise obtaining the respective operational information via one or more VRU Awareness Messages. The method may comprise identifying and/or prioritising a collision avoidance action, optionally using the calculated TTC.
