Embodiment Construction

[0033] The present invention will be further introduced below in conjunction with the accompanying drawings.

[0034] like figure 1 As shown, the satellite communication system of the present invention includes a satellite access part and a 3G core network. The satellite access part includes a satellite terminal, a satellite and a main station, wherein the satellite terminal is used to connect to a local area network, and each satellite terminal can be connected to at least one local area network, and forwards packet data belonging to the local area network. The satellite is used to forward the packet data between the satellite terminal and the main station, and the main station is used to manage the satellite terminal, and the scale of the satellite terminal is generally hundreds of thousands.

[0035] The 3G core network includes SGSN (Serving GPRS Support Node; GPRS: General Packet Radio Service), GGSN (GGSN: Gateway GPRS Support Node), HLR (HLR: Home Location Register) an...

Abstract

The invention discloses a satellite communication system of large-scale satellite terminals. The system comprises a satellite connection part and a 3G (The 3rd Generation Telecommunication) core network. A master station at the satellite connection part is connected with the 3G core network through an Iu interface, and used for forwarding request signaling and grouping service attached by certified satellite terminals to the 3G core network; and the 3G core network processes the request signaling attached by the certified satellite terminals and distributes a service channel used for transmitting the grouping service to a satellite terminal of which attachment is successful. According to the invention, the satellite connection part is accessed into the 3G core network to achieve the management of the large-scale satellite terminals at the satellite connection part by the 3G core network. The invention further discloses a satellite terminal access method for the satellite terminals in the satellite communication system, and the problem caused when the satellite terminals access into the 3G core network is solved by adopting the method.

Description

technical field [0001] The invention belongs to the technical field of satellite communication, and relates to a satellite communication system of a large-scale satellite terminal and an access method for the satellite terminal to access a 3G core network. Background technique [0002] Compared with other communication technologies, satellite communication has unique advantages, especially it is not affected by geographical environment, location distance and other factors. At present, satellite communication technology is developing rapidly, and the emergence of large-capacity broadband communication satellites makes it possible for satellite communication to carry various multimedia services. With the wide application of satellite communication, the scale of its network continues to expand, and the number of terminals connected to the satellite communication system is also increasing. In the past, the management and control of satellite terminals in the satellite communica...
