Abstract

The invention provides a ground-air communication method and device, relates to the field of communication, and can solve the security problem when aircraft sensor equipment transmits data. The method includes: the ground base station receives the data service request message sent by the terminal on the aircraft, and sends a QOS configuration request message to the PCRF; the ground base station receives the QOS configuration response message sent by the PCRF, and the QOS configuration response message includes the QCI corresponding to the APN, and according to The QCI corresponding to the APN determines whether the data service of the terminal is an aircraft sensor device data service or a common terminal data service; if the terminal's data service is an aircraft sensor device data service, the ground base station sends the data packet of the aircraft sensor device data service to the MEC gateway ; If the data service of the terminal is a common terminal data service, the ground base station sends the data packet of the common terminal data service to the core network gateway. The invention is applicable to the process of ground-air communication.

Description

technical field [0001] The present invention relates to the communication field, in particular to a ground-air communication method and device. Background technique [0002] Aviation is an important means of transportation for people to travel quickly. In recent years, the aviation field has developed rapidly, but compared with its leading position in the high integration of materials, control and machinery technologies, airborne wireless communication methods are far behind the rapid development of the information age. footsteps. [0003] With the rapid development of mobile Internet and the increasingly strong demand of users to access the Internet, most airlines hope to rely on ground wireless communication base stations and use ground mobile networks to provide passengers with cheap voice and data broadband services. [0004] During the flight of the aircraft, if the massive data generated by a large number of sensor devices on the aircraft needs to be transmitted in re...
