Embodiment Construction

[0059] The technical solutions in the embodiments of the present invention will be described clearly and in detail below with reference to the drawings in the embodiments of the present invention. The described embodiments are only some of the embodiments of the invention.

[0060] The technical scheme that the present invention solves the problems of the technologies described above is:

[0061] A satellite constellation design scheme that automatically perceives user quality of experience, and obtains the best QoE performance index through information processing of QoE factors and intelligent algorithm calculation. Among them, the coverage performance V(i) corresponding to the communication connection rate is the prerequisite, the blocking rate reflects the communication quality Q(i), the communication rate is affected by the channel capacity C(i), and the communication cost depends on the revenue performance W of commercial satellites (i). According to different QoE indic...

Abstract

The invention relates to a method for automatically sensing the experience quality of a China user on a satellite constellation, which belongs to the technical field of wireless communication and comprises the following steps of: dividing the land area of China into a plurality of regions by using STK, and acquiring a region coverage performance parameter V (i) by using the STK; determining whether the satellite covers the target region or not, and if so, obtaining the Internet of Things equipment density of each region; calculating a communication blocking rate B (i) and communication qualityQ (i); calculating the required capacity C (i) of each region; calculating the communication cost and income performance W (i) of each region; automatically generating experience quality performanceindexes in each grid region of China by using a weighted overall evaluation formula; and taking the QoE factors as optimization target indexes, establishing an experience quality evaluation model, andsolving the optimal experience quality E through a multi-layer tabu search algorithm MTLS. According to the invention, the experience degree of using satellite communication by a user is improved, and the quantitative evaluation of the experience quality is realized.

Description

technical field [0001] The invention belongs to the technical field of wireless communication. Specifically, it relates to a method for automatically sensing the quality of experience of Chinese users on satellite constellations. Background technique [0002] Compared with traditional communication methods, satellite communication has become an important part of the next generation network due to its advantages such as wide coverage, large communication capacity, and high communication quality. However, a single satellite can only cover a part of the Earth's surface, and to achieve full coverage of China requires multiple low-orbit satellites to be placed in different orbits according to certain phase requirements, and to improve the satellite space through reasonable orbit design and constellation configuration. Overall performance of the communication system. Therefore, the primary task of satellite communication system design is satellite constellation design. Reasonab...
