The invention discloses an internet service system using a satellite. In order to form downlink between the satellite and mobile object through marine or land base station, and form uplink between the mobile object and internet, the internet service system comprises an internet, in which the Internet Service Provider access to the internet and provide internet service; a satellite, a satellite base station for transmitting internet service data of internet to the satellite; a PSTN for working mutually with the internet; a marine mobile switch center for managing a plurality of marine base station and working mutually with PSTN; a wireless communication network for managing a plurality of wireless communication base station and working mutually with the internet; and an emitter / receiver mounted on the mobile object for forming downlink with the satellite and forming selectively uplink with marine base station or wireless communication base station, therefore the users can receive internet service.
Description
technical field [0001] The present invention relates to an Internet service system, in particular to an Internet service system using satellites, which can form a downlink between a satellite and a mobile object, and an uplink between a mobile object and the Internet through an ocean or land base station. Background technique [0002] Currently, various Internet services are widely used. Internet service is provided to users who access the Internet through cable networks, such as dial-up modems, ADSL modems, and so on. [0003] In the case of a dial-up modem, an Internet service provider provides Internet service to subscribers connected to the Public Switched Telephone Network (PSTN) through a special telephone number using a Remote Access Server (RAS). Compared with dial-up modems, ADSL modems allow users to receive Internet services quickly. [0004] When a user wants to receive Internet service, he or she must be in a location with access to the cable network. Therefo...
