Patent attributes
A computer server receives messages from a computer device located in proximity to the computer server. The messages are generated by at least one vehicle and translated into IP packets using an N2 control plane interface and an N3 user plane interface implemented in the computer device. A message can include a direction of operation of a vehicle. From a mobile device, information is received describing motion of a user of the mobile device. The information includes a trajectory of the user. The mobile device and the vehicle are located at less than a threshold distance from the computer device. A potential collision is determined between the vehicle and the user based on the direction of operation of the vehicle and the trajectory of the user. An alert is sent to the mobile device indicating the potential collision.
