On the other hand, the traditional wireless resource management and allocation strategy does not consider the quality and actual usage of each channel in the current system, but only allocates the current idle channel or time slot to the user who initiated the application through a certain allocation strategy
Such an allocation strategy will cause some channels or time slots with poor quality to be allocated to the current application, while some channels / time slots with better quality will be idle, and the spectrum resources of the entire system will not be effectively utilized.

Embodiment Construction
[0025] The present invention includes: service application to multi-priority service queue mapping, multi-priority service queue scheduling, wireless resource management and allocation based on spectrum detection, spectrum resource dynamic assignment combined with spectrum quality assessment and interference level and period characteristic analysis components.
[0026] Such as figure 1 , Table 1, and Table 2, according to the division of business types shown in Table 1 and their real-time performance and QoS requirements, the system queues to be processed are first divided into: real-time business queues (highest priority), non-real-time business queues (high Priority) and BoD service queue (low priority); secondly, complete service mapping in the manner specified in Table 2: (1) constant bit rate service (CBR), real-time variable bit rate service (RT-VBR) is mapped to real-time service Queue; (2) non-real-time variable bit rate service (NRT-VBR), available bit rate service (...

A space-borne wireless resource management distribution method comprises the following steps: firstly, mapping different service applications to a real time service queue, a non real-time service queue and a BoD service queue; determining a proportion of processing time of each priority service queue occupying the service processing time according to a service volume and determining a number of service data packets processed at a time in the different priority queues according to the proportion; dividing quality grades of frequency spectrum resources according to a space frequency spectrum detection result, respectively updating and maintaining resource configuration tables corresponding to the different quality grades; distributing the frequency spectrum resources with the different quality grades to the service applications according to the priorities and the types of the service applications; when wireless resource management and distribution are performed to a MF-TDMA system, completing dynamic assignment of the frequency spectrum resources according to interference magnitude and interference time characteristics. By using the method of the invention, the frequency spectrum resources of the system can be used effectively; space-borne dynamic wireless resource management and distribution of a GEO satellite broadband multimedia application can be satisfied.
Description
technical field [0001] The invention relates to a method for managing and allocating satellite-borne wireless resources, which can be widely used in broadband multimedia satellites. Background technique [0002] Broadband multimedia communication satellite is a new generation of communication satellite system that my country focuses on. As one of the key technologies, system wireless resource management and allocation are directly related to system performance and user experience. The requirements for real-time and QoS guarantees of different service types in broadband multimedia satellite applications are very different. The wireless resource management and allocation process of the system needs to reflect the priority of different services and meet the changes in real-time bandwidth requirements of specific services. On the other hand, the traditional radio resource management and allocation strategy does not consider the quality and actual usage of each channel in the cur...
