Embodiment Construction

[0067] 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.

[0068] The technical scheme that the present invention solves the problems of the technologies described above is:

[0069] 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 claims to protect a method for automatically sensing the quality of experience of Chinese users on satellite constellations, which belongs to the field of wireless communication technology, and includes the following steps: using STK to divide China's land area into several areas, and using STK to obtain the area coverage performance parameter V (i); determine whether the satellite covers the target area, and if so, obtain the IoT device density in each area; calculate the communication blocking rate B(i) and communication quality Q(i); calculate the demand capacity C(i) for each area; Regional communication cost and revenue performance W(i); use the weighted overall evaluation formula to automatically generate the quality of experience performance indicators in each grid area in China; use the above QoE factors as optimization target indicators, establish a quality of experience evaluation model, through multiple Layer tabu search algorithm MTLS solves the best quality of experience E. The invention improves the user's experience of using satellite communication, and realizes the quantitative evaluation of the experience quality.

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...
