Abstract:
The present invention addresses a method, apparatus and computer program product for vehicle gateway access in cellular network for vehicle communications. A dedicated Vehicle gateway random preamble is defined to serve the vehicle gateway access to the network in order to resolve the contention during the initial access and thus decrease access latency. In addition to that, a new cause value Vehicle gateway originated data/signaling for the RRC connection establishment request is defined to inform the network that the coming data traffic is from the vehicle communication.
