Problems solved by technology

[0004] At present, ACeS or Inmarsat terminal products on the market can only choose to use one network as the service network, and cannot be compatible with two network systems at the same time, and the terminal network access speed is slow. According to the usual practice, it will first search all 170 RF channels of the satellite network, and read the received signal strength on each RF channel, and calculate the average level. The whole measurement process will last for 3~5s. In a certain period of time, at least 5 measurement samples will be taken from different RF channels. In this way, it will take about 850 seconds to find the channel with the highest power, which will cause the terminal to start up too long.

Embodiment 1

[0041] Such as figure 1 As shown, the satellite terminal network selection and fast access method include the following steps:

[0042] S1: When the satellite terminal is turned on, read the stored resident network parameters, and judge whether the read resident network parameters are valid, if valid, jump to step S2, and if invalid, jump to step S4; the resident network parameters Parameters of the resident network and resident beam when the satellite terminal was powered off last time;

[0043] S2: According to the parameters of the resident network, it is judged whether the last resident network is the Asiastar network or the maritime network; if it is the maritime network, then skip to step S3, and if it is the Asiastar network, then skip to step S5;

[0044] S3: Select the maritime network as the service network, perform network access according to the maritime network parameters, and jump to step S4; in this step, the network access according to the maritime network par...

Embodiment 2

[0062] On the basis of Embodiment 1, in this embodiment, after the satellite terminal starts up, registers on the network, and resides there, it also performs service network switching in the idle state during use. The service network switching process is as follows: figure 2 As shown, specifically: the satellite terminal also periodically measures the adjacent beams of the current serving network in the idle state after starting up, and selects the best beam as the serving beam. If neither the serving beam nor the adjacent beam of the current serving network satisfies When the residency condition is met, judge the current network service type and switch to another network to reside on the network.

[0063] For example, when idle, if the network selected for network access is the Asia-Star network, the adjacent beams of the service beam of the Asia-Star network are periodically measured, and the best beam is selected as the service beam. If neither the service beam nor the ne...

Abstract

The invention relates to the technical field of satellite communication and particularly discloses a satellite terminal network selection and fast network access method and device. The method includes the steps of storing a fast network access channel list of Inmarsat and a fast network access channel list of ACeS in a satellite terminal; only searching beams of the fast network access channel list of Inmarsat or ACeS, determining a service beam among the beams and performing network access registration and residing in the step of starting selection and residing in the satellite network beam of the satellite terminal. The satellite terminal network selection and fast network access method and device can improve the network access efficiency of the satellite terminal, reduce the power consumption of the satellite terminal and enhance the user experience by storing the fast network access channel lists in the satellite terminal and only searching the beams of the fast network access channel lists for network access residing during starting network selection and network access of the satellite terminal.

Description

technical field [0001] The present invention relates to the technical field of satellite communication, in particular to a satellite terminal network selection and fast network access method and device. Background technique [0002] The International Maritime Satellite Communication System (Inmarsat) is a global satellite mobile communication system operated by the International Maritime Organization. Since its operation in 1982, more than 160 countries around the world have used the system, and the users have grown from more than 900 maritime users in the initial stage to Today, there are more than 500,000 users including land and aviation, and the current Inmarsat system has developed to the fourth generation. Asia Cellular Satellite System (ACeS) is a satellite mobile communication system covering East Asia, Southeast Asia and South Asia. The ACeS satellite system is the first system in the world that integrates satellites with terrestrial mobile communication systems. ...
