Embodiment

[0043] Such as figure 1 As shown, the small circle area where the connected user is located in the figure indicates that the small circle contains a number of connected users, and the part of the large circle area except the small circle area indicates that it contains a number of idle users. A method for designing a satellite user side beam applied to a satellite mobile communication system, comprising the following steps:

[0044] Step 1: Set up at least 1 service beam and at least 1 signaling beam on the satellite user side. In the idle state, the user resides in the signaling beam, broadcasts and monitors paging in the signaling beam receiving system; after the user enters the connection state Transfer to the business beam, and the business data transmission is realized by the business beam;

[0045] Step 2: Divide the service area of ​​the satellite into M business wave positions and N signaling wave positions, M>=N, where the value of M is based on the signal-to-noise rat...

Abstract

The invention discloses a satellite user side beam design method applied to a satellite mobile communication system, and the method comprises the following steps: 1, arranging at least one service beam and at least one signaling beam on a satellite user side, and in an idle state, enabling a user to reside in the signaling beam and receive system broadcast and monitoring paging at the signaling beam; after the user enters the connection state, switching to a service beam, and realizing transmission of service data by the service beam; 2, dividing a service area of the satellite into M service wave positions and N signaling wave positions, wherein M>=N, and the value of M is based on the signal-to-noise ratio of a satellite user side link to ensure that the service transmission rate of the connected state user meets the requirement; and the value of N is determined according to the overhead time of the satellite service area, so that the beam switching and reselection of the user are not too frequent. According to the invention, the resource utilization rate of the system can be improved, the service transmission rate is improved, the full coverage of the satellite service area is realized, and the beam switching and reselection times are reduced.

Description

technical field [0001] The invention relates to the field of satellite mobile communication, in particular to a satellite user side beam design method applied to a satellite mobile communication system. Background technique [0002] After the vigorous development of 2G, 3G and 4G, the terrestrial mobile communication system currently serves more than 8 billion users worldwide. However, due to technical and economic factors, it only covers about 20% of the land area. The satellite mobile communication system can solve communication problems in remote areas, oceans, deserts, polar regions and other areas that cannot be solved by ground mobile communication, and has become a useful supplement to the ground mobile communication system. At present, 3GPP has set up a non-terrestrial network (NTN) working group to study the optimization of the technical system of 5G NR and support satellite mobile communication. It can be generally understood that the ground base station is moved ...
