Satellite network and ground network hybrid use method

Abstract

The invention relates to a satellite network and ground network hybrid use method. In the power-on state, equipment continuously detects satellite network and ground network signals and continuously judges whether the equipment can be connected with the satellite network and the ground network or not, when the equipment is judged to be connected with the satellite network and the ground network, one network is selected to be connected with the equipment, and otherwise, the equipment keeps the original state unchanged; the selection principle is that when only the satellite network can be connected, the satellite network is selected; under other conditions, selecting a ground network, and keeping the satellite network in a standby state when a satellite network signal can be detected; whenthe networks selected through two adjacent judgments are the same, the original network connection state is kept unchanged; otherwise, switching the network. According to the method, the switching time is shortened, long-time network interruption caused in the network switching process is avoided, and the user experience is improved.

Description

technical field [0001] The invention belongs to the technical field of satellite communication, and relates to a mixed use method of a satellite network and a ground network. Background technique [0002] Satellite communication technology refers to the processing and transmission of voice, data and images through satellites. At present, it is more and more applied to fields such as exploration, rescue, front-line interviews, navigation and live TV. The satellite network built using this technology does not need ground base stations, and is very suitable for use in remote areas, oceans, and disaster areas. [0003] However, due to the extremely high cost of satellite traffic, the current application range is still relatively narrow. Excessively high traffic costs will hinder the popularization of satellite communication technology, so it is becoming more and more important to save traffic costs as much as possible. Such as figure 1 As shown, the existing satellite communic...
