Example Embodiment

[0029] Earth integrated structure of the embodiment of the present embodiment as converged network figure 1 Indicated. Refer figure 1 One or more communication satellites (base space) space satellite terminal connected to the same or another base station via one or more spatial gateway station (satellite ground station signal) and a core network (Core Network, CN) connected , inter-satellite communications can be performed between the base station spaces, where the core network may be 4G, 5G more advanced communication network or a core network of a communication network. Among them, the satellite terminal can be mobile phones, automotive instrumentation, shipboard equipment, aircraft communications equipment, ground base stations. Refer figure 1 The core network can also be connected to a data network (Data Network, DN).

[0030] In this embodiment, the satellite terminal via GPS, other positioning technology Beidou periodically determine their real-time location, and upload thei...

Abstract

The invention discloses a space-ground integrated fusion network, which comprises a core network and communication satellites. The space-ground integrated fusion network comprises the core network and the plurality of communication satellites, wherein the core network performs routing selection on a set formed by a first communication satellite group and a second communication satellite group, and the plurality of communication satellites determined by the routing selection initiate paging to a satellite terminal, the first communication satellite group and the second communication satellite group respectively comprise at least one communication satellite, an elevation angle of the communication satellite in the first communication satellite group relative to the core network is maximum, and an elevation angle of the communication satellite in the second communication satellite group relative to the satellite terminal is maximum. According to the space-ground integrated fusion network, the reliability of all available communication satellites is considered globally, on one hand, the advantages of acquiring the shortest topological path and the like of a routing selection algorithm can be played, and the properties of channel bandwidth, average communication traffic, communication overhead, queue length, propagation delay and the like of routing can be improved. The space-ground integrated fusion network is widely applied to the technical field of satellite communication.

Description

Technical field [0001] The present invention relates to satellite communication technology, and in particular an earth integrated converged network, and core network paging method. Background technique [0002] Currently experiencing technical concept "6G = 5G + satellite network", that is, to achieve 6G network through a mobile satellite network and 5G mobile networks, the technical idea is to take advantage of mobile LEO satellite networks compensate for the lack 5G and other mobile networks, such as let mobile communication signal coverage the air, oceans, forests, deserts and other sparsely populated areas, to achieve a truly global communication. However, the mobile satellite network are also some shortcomings column, such as the communication distance, the power density, multiple antenna deployment, which makes a satellite mobile communications have a more limited network, satellite communication spectrum efficiency is much lower than the cellular mobile communication syste...
