Paging method, positioning information sending method, core network node and base station

Abstract

The invention provides a paging method, a positioning information sending method, a core network node and a base station, and relates to the technical field of communication. The paging method is applied to a core network node in a satellite Internet communication system, and comprises the following steps: obtaining a setting mode of a tracking area TA in the satellite Internet communication system; determining a base station for paging the terminal according to the setting mode; sending a paging message to the base station, wherein the setting mode comprises one of the following modes: dividing the satellite Internet communication system into a TA; setting at least two fixed TAs; and setting at least two non-fixed TAs. According to the scheme, the base station used for paging the terminalwhen the terminal needs to be paged is determined according to the setting mode of the TA in the satellite Internet communication system, so the paging process in the satellite Internet communicationsystem is perfected, and the communication reliability of the satellite Internet communication system can be ensured.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a paging method, a positioning information sending method, a core network node and a base station. Background technique [0002] Satellite Internet has the advantages of wide coverage and little impact from natural disasters and physical attacks. It can be deeply integrated with the terrestrial mobile communication network (5G) network to make up for the lack of coverage of the terrestrial mobile network, and form a converged network system with complementary advantages, close integration, and three-dimensional layering with the terrestrial network to realize information transmission and communication on a global scale. interact. [0003] The satellites in the satellite Internet are divided into geostationary satellites, medium-orbit satellites and low-orbit satellites; the distance of low-orbit satellites is characterized by being relatively close to the ground, and the c...
