Abstract
A mobility management method includes: obtain a terminal a first position of a terminal from a geo-synchronous orbit (GEO) positioning satellite; the terminal searches for a first communication calendar according to the first position, and determines a network connection mode of the terminal; when it is determined that the network connection mode is an NGSO satellite connection, the terminal accesses a network by means of a first NGSO satellite and sends, by means of the first NGSO satellite, a first request message carrying the first position to the network.
Claims19
A mobility management method, applied to a terminal in an integration network, wherein access networks of the integration network comprise a satellite access network and a terrestrial access network, the satellite access network comprises a plurality of Non-Geostationary Orbit (NGSO) satellites, and the method comprises:
- obtaining a first position of the terminal from a Geo-synchronous Earth Orbit (GEO) positioning satellite;
- looking up, by the terminal according to the first position, a first communication calendar to determine a network connection mode of the terminal, the first communication calendar comprising an NGSO satellite ephemeris and/or a terrestrial communication calendar;
- when determining that the network connection mode is NGSO satellite connection, accessing, by the terminal, a network through a first NGSO satellite and sending, by the terminal, a first request message carrying the first position to the network through the first NGSO satellite.
A mobility management method applied to a core network in an integration network, wherein access networks of the integration network comprise a satellite access network and a terrestrial access network, and the satellite access network comprises a plurality of Non-Geostationary Orbit (NGSO) satellites, the method comprises:
- receiving, by the core network, a request message sent by a first NGSO satellite, the request message carrying a position of a terminal, and an identifier and beam identifier of the first NGSO satellite;
- and
- in a case that the terminal is a trusted terminal, performing position update for the terminal according to the position of the terminal, and the identifier and beam identifier of the first NGSO satellite carried in the request message,
- wherein the request message is any one of following messages:
- an initial communication request message for requesting to access for a first time;
- a connection update request message for requesting to update a network connection mode;
- a position update request message for requesting to perform position update;
- and
- a satellite switch request message for requesting to switch NGSO satellite.
A terminal in an integration network, comprising:
- a processor, configured to obtain a first position of the terminal from a Geo-synchronous Earth Orbit (GEO) positioning satellite, and look up a first communication calendar according to the first position to determine a network connection mode of the terminal, the first communication calendar comprising a Non-Geostationary Orbit (NGSO) satellite ephemeris and/or a terrestrial communication calendar;
- and
- a transceiver, configured to access a network through a first NGSO satellite and send a first request message carrying the first position to the network through the first NGSO satellite when determining that the network connection mode is NGSO satellite connection;
- wherein, access networks of the integration network comprise a satellite access network and a terrestrial access network, and the satellite access network comprises a plurality of NGSO satellites.
