Method and device for collecting and updating perception pilot frequency channel information

The invention provides a method and a device for collecting and updating perception pilot frequency channel information, relating to the perception pilot frequency channel technology. The method for collecting perception pilot frequency channel information comprises steps that: a perception pilot frequency channel management system sends a request for reporting network information of an area covered by the perception pilot frequency channel management system to a radio network controller; the radio network controller collects the network information according to the request of the perception pilot frequency channel management system and feeds back the network information to the perception pilot frequency channel management system; and the perception pilot frequency channel management system carries out meshing planning on the area covered by the perception pilot frequency channel management system by a meshing algorithm according to the obtained network information and stores the network information in a database of the perception pilot frequency channel management system by gridding. The invention continuously collects and updates the stored network information by real-time perception of the radio environment, thereby improving the accuracy of the perception pilot frequency channel information.
