Method, equipment and system for scheduling and distributing wireless resources of aeronautical mobile communication system

Abstract

The invention discloses a method, equipment and a system for scheduling and distributing wireless resources of an aeronautical mobile communication system, wherein the method for scheduling and distributing the wireless resources of the aeronautical mobile communication system comprises the following steps of: acquiring a reverse chain path resource request of each terminal of the aeronautical mobile communication system; triggering to acquire the channel quality estimation of each terminal according to the corresponding reverse chain path resource request; self-adaptively selecting a new modulation-demodulation coding-decoding mode for the corresponding terminal according to the corresponding channel quality estimation; redetermining the new resource request quantity of the corresponding terminal according to the new modulation-demodulation coding-decoding mode; and distributing the wireless resources for each terminal according to the redetermined new resource request quantity of each terminal. The method, the equipment and the system disclosed by the invention can effectively enhance the channel utilization ratio of aeronautical mobile communication and can ensure the communication property of the aeronautical mobile communication system in a complex and changeable aeronautical channel environment.

Description

technical field [0001] The present invention relates to aeronautical communication technology, in particular to a method, equipment and system for scheduling and assigning radio resources in an aviation mobile communication system. Background technique [0002] With the development of aviation communication technology, the L-band Digital Aeronautical Communication System (LDACS) based on broadband technology, namely LDACS-1, has become one of the key technologies of the future digital aviation communication system. In -1, the scheduling and allocation method of wireless communication resources adopted by the communication system has an important impact on the fairness of resource usage, service quality, and communication performance by each user terminal. [0003] At present, one of the scheduling and allocation methods of wireless communication resources adopted by the aviation mobile communication system is: the base station in the communication system allocates wireless c...

Problems solved by technology

[0004] The above-mentioned polling-based method can only allocate channel resources for resource requests of user terminals. Since the channel quality environment of the communication system is complex and changeable, when the user terminal communicates using the channel resources allocated by the base station, due to channel quality changes, The performance of effectively transmitting data may have changed, so this resource allocation method cannot effectively guarantee the communication performance of the communication system in the complex and changeable air channel environment
