Embodiment 1

[0027] A satellite system network access method, the method is used when the satellite terminal equipment performs network registration after starting up, restarting or network connection interruption, comprising the following steps:

[0028] A. To determine the validity of the SIM card;

[0029] B. Select the service beam: read the network access channel from the storage module, the network access channel includes the preferred network access channel and / or prior network access channel, if the service beam can be determined from these beams, then perform network registration and registration from the service beam Residing; if the service beam cannot be determined from these beams, determine the service beam from the network access channel other than the above-mentioned network access channel and perform network registration and residence.

[0030] The network access channel may be one or both of the preferred network access channel and the prior network access channel. When ...

Embodiment 2

[0032] Based on the principle of Embodiment 1, this embodiment discloses a detailed implementation manner in which the network access channel may be a preferred network access channel and a priori network access channel.

[0033] The validity of the judgment of the SIM card is specifically the following method: read the IMSI information in the SIM card, the SIM card and the PLMN mapping table stored in the terminal storage module, and judge the validity of the SIM card. If the SIM card is valid, then perform Step B, in this step, the method of judging is that if the IMSI information is in the mapping table between the SIM card and the PLMN, then the SIM is valid, otherwise it is invalid. If the SIM card is valid, the information that the SIM card is invalid will be fed back to the user, so as to prevent the user from waiting for a long time for network registration and being unable to use the device.

[0034] When selecting the service beam, first search for the beam in the pr...

Embodiment 3

[0038] Based on the above embodiments, this embodiment discloses a device for implementing the above method.

[0039] A satellite system network access device, comprising:

[0040] Storage module: used to store the preferred network access channel table and / or the prior network access channel table;

[0041] Satellite network beam search module: when performing beam speed selection, first search according to the network access channels stored in the storage module; if the service beam cannot be determined in the network access channels stored in the storage module, then search for other than the network access channels stored in the storage module Incoming channels to determine serving beams;

[0042] Satellite network resident module: used for network registration and resident according to the service beam determined by the satellite network beam search module.

[0043] When the satellite network beam search module selects the service beam, the scheme in Embodiment 2 can be...

Abstract

The invention discloses a network access method and device of a satellite system. The method comprises the following steps of: A. determining validity of an SIM card; and B. selecting a service beam:reading network access channels from a storage module, wherein the network access channels comprise an optimal network access channel and / or a prior network access channel, if a service beam can be determined among beams, performing network access registering and residing through the service beam; if a service beam cannot be determined among beams, determining a service beam in other network access channels except the mentioned network access channel, and performing network access registering and residing. Through adoption of the network access method, network access time is shortened to a great extent, power consumption of a terminal device is lowered, and user experience is enhanced.

Description

technical field [0001] The invention relates to the field of communication methods, in particular to a satellite system network access method. Background technique [0002] At present, mobile cellular communication is very popular, and 2G / 3G / 4G mobile phone communication has become the main means of daily communication, but it still cannot achieve global coverage. Wired communication is not only expensive but also difficult to operate and maintain. Moreover, mobile cellular communication equipment relies on the services of ground stations and is greatly affected by the environment. In oceans, mountains, grasslands, deserts and many remote areas, mobile cellular communication cannot be realized, and mobile phones have almost lost their communication capabilities. [0003] Satellite communication has the characteristics of wide coverage, not affected by natural environment and geological disasters, etc. It has high security and reliability, and can be used as an effective sup...
